This System of Surgery is intended to meet a growing want created by the great progress which Surgery has made during the past few years. It is with a view to i'ulfil this object tliat men of recognized authority in their respective branches have consented to contribute in order to present to the profession a comjilcte review of the domain of modern Surgery — a domain whicli has so wonderfully enlarged its bound- aries through the achievements rendered possible by the systematic employment of antiseptic and aseptic methods of procedure. The task has been most onerous, but the labors of an eminent corps of contribu- tors have enabled the Editor to oiFer to the profession a concise and complete work, presenting the most advanced opinions upon the new problems involved in modern surgery, as well as the practical details which conduce to success in treatment. In accomplishing this it is gratifying to be able to announce that the whole has been the work of American surgeons, and that it may be fairly said to represent the most advanced condition of American Surgery. The Editor takes this occasion to acknowledge his obligations to the contributors, each one of whom is a teacher of Surgery or a director in some large surgical clinic or hospital, and who, for this reason, is capable of speaking with clinical authority from an experience based on the study and observation of a large number of cases. Each department is thus treated by an acknowledged master of the subject, who is able to present the most modern and advanced views in the most cogent and demonstrative way. The Editor trusts that he will be found to have succeeded in the endeavor to present a work of the scope and breadth that this great subject demands, and that an appreciative reception will be accorded to the results given by the contributors, who, though busy men, have con- sented to offer the fruits of their labors for the benefit of the medical profession. The Editor especially, desires to acknowledge, with sincere thanks, the great assistance accoi'ded to him by Dr. John S. Billings, through whose valuable services and co-operation he has been enabled to bring before the profession this work in its present comprehensive and at the same time compact form.

THE HISTORY AND LITERATURE OF SURGERY. By JOHN S. BILLINGS, M. D. In this sketdi of the development of Surgery during the last three thousand years a brief account is given, mainly in chronological order, of the chief discoverers, improvers, and inventors in the art, and also of the principal teachers of it. The original in\-entor may or may not have been a lecturer or author, and the date of the first improvement in a method of treatment or in the performance of a new operation was often long prior to that general knowledge of such improvement which is necessary to constitute true development. Some account is also given of the trade, guild, or craft associations or corporations of surgeons, and of their relations to education and to legislation. A few illustrations of the state of the art at diflFerent periods, in the shape of the recommenda- tions of different writers with regard to methods of treatment of certain injuries or diseases, are presented ; but no attempt is made to trace the history of the growth of knowledge with regard to each particular form of disease or oj:)eration, this being left to the writers of monographs on these particular subjects. It requires leisure, patience, and access to a large library to make historical studies really interesting, and the most I can hope to accom- plish in this paper is to furnish to the physician who has little time, taste, or opportunity for consulting the original documents the means of ascertaining the periods and places in which the leading surgeons of the world have done their work. The jirinted literature of surgery is vast in quantity, and the great majority of it is obsolete and practically use- less : even for statistical ])urposes the records of operations performed prior to 1870 have now lost much of the value which they possessed at that date ; yet in many respects the old surgical monographs, col- lections of cases, and systems are the most definite and interesting of all ancient medical literature. To really enjoy the history of surgery it is necessary to consult the original documents — to get the flavor of the quaint phraseology of the older writers. No discourse about the surgical kno\\ledge of Hippoc- rates, however eloquent" and eulogistic it may be, can give such an idea of his teachings as is to be obtained from a perusal of his writings. It is not to be expected that a man who is familiar with the resources of the surgery of the present day will he al)le to discover in the ancient records anything of much practical utility in his daily work which will be new to him ; nevertheless, if he desires to compare his experience in a particular case or class of cases with tliat of his predecessors — to obtain, Vol,. I.— 2 17 18 THE HISTORY AM) UTKnATrUK OF SUltOKRY. as it were, a sort of "parallax in time" of the views wliieli liave been held on tlie subject whieia occupies him — he will often not be able to do this from the (current text-books. It will be neeessarv that he should go back to the old masters, road, comi)are, and think ; and whenever he does this it is safe to say that his eonclusions will be broader, wiser, estal)lished on a firmer foundation, and more interesting to those to whom he imparts them, than they ^\■ill be if derived solely from his own experience. In the history of the development in civilization of nations and peoples, surgery almost necessarily precedes internal medicine with regard to accurate observation of lesions of the human body and of their results. Speculations about humors and fluxes, Idack bile and medical constitu- tions, vital spirits and the doctrine of signatures, did not much occupy the minds of the men of old in their attempts to note and describe the signs of different forms of fractures and dislocations, the danger of wovmds in diti'erent localities, the different varieties of tumors, or the treatment of a calculus in the bladder or of a hernia. Of the many remedies in the form of drugs, sahes, embrocations, and jjlasters M'hich are described at length in the ancient medical books which have come down to us, hardly more than twenty are now in ordinary use ; the ancient physiology and pathology are, for the most part, now considered as being merely curious illustrations of human error; and it is only a portion of the anatomy and siu'gery of the ancients that remains as an essential part of the foundation of the art cif medicine as it exists to-day. The history of surgery is inextricably mingled with that of medicine, and the best literature on the subject is to be found in some of the larger formal treatises on the history of medicine. It has, however, been treated of as a special branch of the art in a goodly number of Ijooks and essays, the titles of a portion of which fill se\'en pages of volume xiii. of the Index Catalogue of the Librarv of the Surgeon-General's Office at Wash- ington. The earliest records in our possession which relate to surgical opera- tions come from Egypt. It is true that human skulls have been found belonging to the Neolithic or Polished Stone Age, which have had por- tions removed — being examples of the so-called jjrehistoric trephining which is suj)posed to have been performed in cases of headache, epilepsy, etc. — and the age of these relics is unknown ; but it is not at all probable that it extends to the time of the pyramid-builders in the valley of the Nile, when circumcision had been established as a religious rite and an official system of medicine was in process of construction. The Papyrus Ebers, written 1552 b. c. — that is, at least a century bef(Sre the exodus of the Israelites — is a comj)ilation of receipts and directions for the treatment of various diseases, many of which formulae it refers to as being then ancient. Among these is a short section on tumors near the surface of the body, in which it is said : " If this tumor goes and comes under your finger, trembling even when your hand is still, say, ' it is a fatty tumor,' and ti'eat it with the knife, after which treat it as an open wound." From the Papyrus Ebcrs we learn that there were physicians in Egypt who were not priests, and the same may be iiiferred from the statement in Genesis (eh. 1. 2) that " Joseph com- manded his servants the physicians to embalm his father, and the phy- THE HISTORY AM) LITERATURE OF SURGERY. 19 sicians embalmed Israel." The word in this text wliieh is translated "phvsieians" is rephaiin, and it is sometimes translated as "dressers of wounds " — /. c. surueons. The embalmers probably had a little more anatomical knowledge than the physicians of the time ; but the Egyjit- ians had a treatise on anatomy which, according to Manetho, was attrib- uted to Ath(itliis, the son of Menes, who reigned 5241 B. c. The few allusions to medicine scattered through the books of the Old Testament indicate that the general belief was in accord with that usually found prevailing among savage tribes — viz. that most diseases are punishments intlicted by divine power, and to be removed by sacri- fices and special ceremonies ; whence it follows that the priests were the chief medicine-men. That there were other physicians is probable from the grimly sarcastic account of King Asa, who " in his disease sought not to the Lord, but to the physicians. And Asa slept with his fathers ;" and also, perhaps, from Exodus xxi. 19 : "And if men strive together, and one smite another with a stone, or with his fist, and he die not, .... then shall he that smote him pay for the loss of his time, and shall cause him to be thoroughly healed ; " or, as the Sef)tuagint has it, " and shall pay the physician's fees." The medicine of the Bible has been the subject of several learned essays, but it does not appear that medicine was regularly studied among the Jews as a separate profession until the rise of the Alexandrian School, nor does either the science or the art of medicine owe anything to this nation until after this period. The often-quoted chapter xxxviii. of Ecclesiasticus about the physician is of late date, and was probably written under Greek influence. Some specimens of Jewish surgery prior to 200 A. d. are to be found in the Talmud. The ralibis were acquainted with sutures for wounds, with the method of freshening the edges of an old wound to obtain reunion, with the employment of the uterine sound to learn whether the blood came from the uterus or vagina, the operation for imperforate anus, and also with an;esthctic substances with which they used to diminish the jwin of a surgical operation or capital jtunishment.' Thev understood the application to the body of artificial jjarts, as for supplying the loss of substance of the trachea and replacing the loss of substance of the cranial bone ; they knew artificial teeth, wooden legs, as also various forms of apparatus for the unfortunates who were deprived of the use of their lo«er exti'emities. The first allusions to surgical subjects in Greek literature are found in the poems of Homer, which may be accepted as dating from about 1000 B. c, whatever may be thought as to the reality of the siege of Troy or the identity of Homer himself. In these poems mention is made of ^Escnlapius, not as a god, but as a well-known and distinguished physician, and of his sons INIaciiaon and Podalirius as surgeons and war- riors. The works of Homer have been carefully examined and analyzed by ^lalgaigne and Darcmberg with reference to medical and surgical matters, and their conclusions may be briefly stated as follows:^ ' Rabbinowicz : Ixi Medecine {hi Thdhnu/l, etc., Paris, 1880, p. xliii. ^ " Essai sur I'Histoire et rOrganisation de la Chirurgie et de la M^decme grecqiies avant Hipjiocrate,'' par M. Malgaigiie, Jour, de Med., iv. 303, Paris, 1846 ; La Medecine dans HomSre, par Ch. Daremberg, 8°, Paris, 1865. 20 THE HISTORY AND LITKRATVRE OF SUIiGERY. Among tlie Greeks were certain surgeons whose knowledge and skill were highly esteemed ; many of the warriors knew how to dress and bandage wounds, and some of the Grecian women had the same skill, corresponding to that possessed by the wives of tlie noi)ility in Western Europe in feudal times. The dressings aj)plied to the wounds a|)pcar to have been for the most part simple emollients : the effused blood was pressed out, the surface was washed with warm water, certain crushed roots or bruised leaves were applied to check hemorrhage. Over forty Mounds in different parts of the body are described with more or less detail, and in such a way as to indicate that Homer gav(> the residts of actual observation and experience ; and in the course of these descriptions a nomenclature is used which, anatomically, is much the same as that employed by Hippocrates. The different effects of Avounds in different parts of the body are referred to, and a curious illustration of this occurs in the description of the injury of one of the horses of Nestor by an arrow from the bow of Paris (viii. 81-86). The wound was on the top of the head, penetrating to the brain, and it is said that the injured animal was convulsed and turned round and round the pole. This, as INIalgaigne points out, corresponds to the modern discovery that such movements of rotation are produced by an injury of the cerebellum. The anatomical terms used by Homer relate mainly to the exterior of the body, and do not imply any greater knowledge of internal struc- ture tlian is possessed by every butcher ; but his allusions to the fatality of certain wounds embody tlie results of considerable experience. There is nothing of surgical interest in Greek literature between the time of Homer and that of the Hippocratic Writings, unless it be the passage in Aristophanes in which the slave of Lamachus calls for hot-water com- presses, etc. with which to dress the sprained ankle of his master. In the fifth and sixth centuries B. c. there were in Greece and Great Greece between fifty and sixty temples of ^sculapius, all of which were probably resorted to by the sick, but those which became specially cele- brated were those of Rhodes, Cyrene, Cnidos, and Cos. Those at Ciiidos and Cos gradually became the most famous, and their so-called " schools " occupy a prominent jjlace in the history of medicine. By the term "medical schools" as applied to Cos and Cnidos it is not meant that these were places for the jiublic teaching of medicine, but rather that they Avere j)laces where certain medical families had settled, and in each of which certain peculiar theories and methods of treatment prevailed, the phrase " school " being used nuich as we Mould noM' speak of the "French" or the "Munich" school in painting. In the vicinity of these temj)les there seem to have collected physi- cians M'ho Mere not priests, and M'ho belonged to an association or bro- therhood, the members of which either claimed to be descendants of ^sculapius or M'ere admitted to the guild by ad()ption M'ith sjjecial cere- monies. These were knoM'n collectively as the "^Esclepiadje," and much confusion has arisen from the erroneous ajjplication of this term in later times to those M-ho ministered in the temple. There is no doubt that the ]iricsts of the temj^le gave medical ad\ice, but, if Me are to judge from the specimens preserved to us in the forms of inscriptions and memorial tablets, it M'as not the sort of advice of Mhich any use is made in the medical treatises of the Hippocratic school. THE HISTORY AND LITKRATVEE OF SURGERY. 21 It is probable that the real or lay physicians kept records which were handed down from father to son, and were jireserved as a valnable family heritage. That medicine was thus hereditary we know from the ilip- pocratic oath, and from the genealogies which are given of many of the celebrated physicians of Greece. According to Bertrand, this custom has come down to the present time. On one of the slopes of Pindus there are still five or six villages the inhabitants of which are supposed to be born phvsicians and surgeons, each family having its own specialty and its inherited tradition. If a son is wanting, the child of a stranger is adopted. There is no evidence that those who visited the temples seeking mirac- ulous cures were examined or treated by lay physicians, but there were certain attendants called zacoroi who received the patients and assigned them to ])laces beneath the porticos; and from tlie information collected by them it is possible that the priest who impersonated the god, appearing in the night-watches, may sometimes have formulated his prophecies and instructions. The doctrines of the schools of Cos and Cnidos were committed to writing, the first work of the kind coming from the school of Cnidos, being what is known as the " Cnidian Sentences." Of this treatise there were at least two editions, and it was in existence in the time of Galen. A portion of it has been preserved to us in what are known as the Second and Third Books of Diseases, and in the Treatises on Internal Affections contained in the Hippocratic collections. In this portion four diseases of the kidneys are described. In the first there is acute ])ain in the loins, groin, and the testicle of the affected side (renal colic) ; there is frequent urination, with gradual suppression of urine and passage of .sand, causing pain in the urethra. A2>ply warmth and purge with scammony. If the pain is great, use large euemata of warm ■water ; if a tumor forms, make an incision over the kidney and evacuate the pus. Such incision gives a chance of recovery ; without it death will follow. In the second form of disease of the kidney there are violent pains, as in the preceding form. The patient passes blood with his urine at the commencement of the disease, which is followed, after a time, by pus. If he preserves a strict rest, he will be cured rapidly, but if he makes effort, the pains will become sharper. When the kidney is filled with pus it swells out near the spine ; in this case make, over the swelling, an incision, generally deep, into the kidney. If you succeed in the incision, you will cure the patient at once ; if you fail, it is to be feared that the wound will not close, and the borders of the wound will contract and the cavity of the kidney will be filled with pus ; if this passes inward and is evacuated by the rectum, there is a chance of health ; but if it affects the other kiduev, death is to be feared. Evacuants are to be used, and the same regimen as for the preceding case. Very often this disease termi- nates by a renal phthisis. The school of Cos followed with its collection of maxims, the " Prse- notiones CoaciB." Its doctrines will be best considered in the work of its most illustrious disciple, Ilipiiocrates, who was born at Cos about 460 B. c. His father, Heraclidcs, and his grandfather were physicians, and he received his earlv education at tlie school of Cos, after which he went 22 THE HISTORY AND LITERATURE OF SURGERY. to Athens and continued lii.s studios, re(rivin<:, the liest echication which the Golden Age of Greek civilization could furnish. The collection known as tiie "Hippocratic Writiuirs" dates from a period about the time of Aristotle. Only a jxd'tion of these writinj^s are the works of Hippocrates himself; several are probablv of more ancient date — two at least appear to belong to the Cnidian School, and some are by his disciples. On the otlier iiand, some of those which once belonged to this collection have been lost. The books in the Hijjpocratic collection which treat more especially of surgical affections and o]x'rations, and which are accc2)ted bv most commentators as having been written eitiier by Hippocrates himself or by one of his immediate pupils, are those on injuries of the head, on fraetui'es, on the articulations (/. e. on dislocations), Mochlicns (on the bones and their injuries and displacements, and on apparatus), on M'ounds and ulcers, on fistulfe, on hemorrhoids, and on the latrium or the Physi- cian's Establishment, or the Surgery. The book on injuries of the head liegins witli a description of the sutures of the cranium and of the bones ol" the skull, in which it is stated that the number and position of the sutures varies with the form of the head ; that the coronal suture is wanting when there is no anterior pro- tuberance of the skull, and the lambdoid suture is wanting when there is no posterior protuljerance. As this does not agree with the oI)serva- tions of modern anatomists, the commentators have much troul^le to explain it, since they are unwilling to atlmit that Hippocrates made a mistake in observation, or even that he generalized from insufticicnt data ; which last is the most probable explanation. He divides injuries of the bones of the skull into five classes — viz. simple fissures, contusions without fracture or depression, fractures with depression, indentations of the outer tabic, and fractures at a distance from the place of injury, or fracture l)y coutrc-coup. AVith regard to this last he says : " There is no remedy, for vhen this mischief takes place there is no means of ascertaining by any examination whether or not it has occurred, or on what part of the head." He then goes on to say : " Of these modes of fracture the following require trepanning : the contusion, whether the bone be laid bare or not ; and tiie fissure, \\hether apparent or not ^V bone depressed from its natural jiosition rarely requires trepanning, and those which are most jjressed and broken require trepanning the least." It will be seen that this is quite different from the rules of modern practice. For wounds of the head he forbids the application of any liquors or cataplasms or tents, unless the wound is on the forehead or the part which is bare of hairs or about the eyebrow and eye. The wound is to be extended by incisions for the purpose of examining tiie bone when- ever it is suspected that this is injured ; and it is remarked that these incisions may be practised with impunity except on the temjile and the parts above it, where there is a vein that runs across the temple, in which region an incision is not to be made ; " for convulsions seize on a person who has been thus treated ; and if the incision be on the left temple, the convulsions seize on the right side ; and if the incision be on the right side, tlie convulsions take place on the left side." THE HISTORY AXD LITERATURE OF SURGERY. 23 Tho books on fractures and on the articulations, together with the book called " Mochlicus," contain sketches of the anatomy of the bones and of the joints, and accoiuits of various forms of dislocations of the diti'erent joints, with detailed instructions as to reduction and as to the mode of bandaging in cases of fracture. Special attention is given to the subject of injuries affecting the knee-, the elbow-, and the ankle-joints. The paragraph on disk)cations of the knee does not correspond to the experience of modern surgeons. It is as follows : " Luxations and sub- luxatitins at the knee are much milder accidents than subluxations and luxations at the elbow ; for the knee-joint, in proportion to its size, is more compact than that of the arm, and has a more even conformation, and is rounded, while the joint of the arm is large and has many cavities " Owing to their configuration, the bones of the knee are indeed fre- quently dislocated, but they are easily reduced, for no great inflanniiation follows nor any constriction of the joint They are displaced for the most part to the inside, sometimes to the outside, and occasion- ally into the ham. The reduction in all these cases iS not difficult, but in the dislocations inward and outward the patient should be placed on a low seat, and the thigh should be elevated, but not much. Moderate extension for the most part sufficeth, extension being made at the leg and counter-extension at the thigh. " Dislocations at the elbow are more troublesome than those at the knee, and, owing to the inflammation which comes on and the config- uration of the joint, are more difficult to reduce if the bones are not inuuediatcly replaced. For the bones at the elbow are less subject to dislocation than those of the knee, but are more difficult to reduce and keep in their position, and are more apt to become inflamed and ankylosed." Some of the older surgeons concur with Hippocrates in speaking of dislocations of the knee as comparatively fre(pient, whereas at present they are very rare. Dr. Adams supposes that the wrestlers at the public games, who furnished Hippocrates with a Uu'ge proportion of his cases of fractures and dislocations, may have been especially liable to this accident. Hippocrates says that he knows of but one way in which the shoulder-joint is dislocated — namely, that into the armpit ; but he does not deny that the head of the humerus might be dislocated upward, out^ ward, or forward. The methods of reduction are fairly described, and are substantially those which are used at the ])reseut day. He has much to say in various places about congenital dislocations, some of which may be reduced to their natural condition, and especially those at the ankle-joint. In cases of compound dislocations he forbids reduction, as a general rule. For example, in" speaking of dislocation at the ankle-joint com- plicated with an external wound, he says you are not to reduce the parts, but let any other physician reduce them if he choose ; " for this you should know for certain, that the patient will die if the parts are allowed to remain reduced, and that he will not survive more than a few days, for few of them pass the seventh day, lieing cut off" by convulsions ; but sometimes the leg and foot are seized witii gangrene But if not reduced nor any attempts first made to ri'(hice them, most of such cases 24 THE HISTORY AND lATERATURE OF SURGERY. recover. The leg and foot are to lie arranged as the patient wishes, only they must not be ])iit in a dependent jiosition nor moved ahout." In speaking of these eomj^nnnd dislocations he makes no allnsidii to cutting ofl' the protruding end of the bone, but in another section he remarks that " complete resections of bones at the joints, whether the foot, the hand, the leg, the ankle, the forearm, the wrist, for the most part are not attended with danger, unless one be cut oif at once by de- li([uiiun animi or if eontiiuial fevers supervene on the fourth day." Hippocrates knew nothing about amputation of lindjs as an o])eration through living parts or with a view to forming a stump of a particular shape. In cases of gangrene due to the crushing of the blood-vessels, or following fractures when the bandages have been applied too tightly, he remarks that the most of such patients recover, even when a portion of the thigh conies away or of the arm, and when the forearm and leg drop oif the patients rapidly recover. The sui'gical part of the Hippocratic collection is much more in accordance with modern views than the medical part ; but there are certain characteristics of all the books generally considered to have been written by Hippocrates himself which are worthy of special attention in connection with the high repute in -which they ha\e been held by med- ical men for over two thousand years. In the first place, it is evident that one of his special aims was to be entirely honest and truthful in his statements. He reports no marvellous cures, no sjiecimens of extraor- dinary success in diagnosis where others had failed; fatal cases are given as well as recoveries, and there are no hints that the former were not seen in time or that they had been improperly treated by others. He seems to have written mainly for the purpose of telling what he himself knew ; and this motive — i-ai-e among all writers — is especially rare among writers on medicine. A second characteristic of the Hijipocratic Writings is the special attention given to those symptoms which indicate the effect which the disease is producing upon the body as a whole, including such phenomena as fever, debility, delirium, restlessness, and so-called critical discharges of various kinds ; while the special diagnostic signs of particidar forms of disease of particular organs are given much less attention. The aphorism of Hippocrates concerning the efficiency of fire — namely, " that diseases which are not cured by medicines are cured by iron ; those which are not cured by iron are cured by fire ; those not cured by fire are incurable " — has been the cause of an enormous amount of suifering and of bad surgery to nearly the present centuiy. Surgery of India and China. In the literature of India the first definite hymns, invocations, and charms connected with medicine are foiuid in the fourth (or Atharva) Veda. The oldest existing medical work is the Charaka-samhita, of which the Sanscrit text has been published in 1877, and of which an English translation is now in course of publication. Somewhat later, probably, is the Susruta, of which two Sanscrit editions have been pub- lished ; also a Latin translation by Dr. F. Hessler, published at Elrlangen in 1844. English translations are in progress of publication, and a sum- THE HISTORY AXD LITERATURE OF SURGERY. 25 marv is given bv Dr. Wise in his history of Indian medicine. Botli Charaka and Susruta profess to be, and are commonly said to be, commen- taries on the Aynr-Veda — /. e. the Veda of Life — but, in tact, there is no such work as the Ayur-Veda distinct from and preceding Charaka and Susi'uta. The date of composition of these works is unknown, and is variously estimated at from 1000 B. c. to 700 A. D. Recent authorities consider that the later date is the more probable one, and that the work took its jiresent form under the influence of ideas derived from the Alexandrian School and the early Arab writers. It was certainly known in tiie ninth century A. D. Nevertheless, it shows little trace of a knowledge Iw the author of the Hippocratic Writings or of the discoveries of the Alexandrian anato- mists and surgeons, and it contains a number of things peculiar to itself and probably derived from ancient Indian traditions. The translation of Susruta by Anna Moreshvar Kunte, of which the first numbers were published in Bombay in 1877, begins as follows : "Salutation to Brahma, Prajapati, the twin Asvins, Iiulra, Dhan- vantari, Susruta, and others. " Now, hereafter, we .shall narrate the chapter named the descent of knowledge (of medicine) just as it was taught to Susruta by the \enerable Dhanvantari. Aupadhenava, Vaitarana, Aurabhra, Paushkalavata, Kara- virya, Gopura, Rakshita, Susruta, and his other friends in earnest addressed the venerable Dhanvantari, the respected of gods (then known by the name of Divodasa), the descendant of Kasiraja, who was leading the life of a hermit, surrounded by a number of sages : ' Sire ! we arc moved with compassion, seeing human beings, though protected (by their kings), yet quite helpless, being afflicted with numerous bodily, mental, natural, and accidental maladies. We wish to be instructed in the Science of jNIedicine for the sake of jiublic good, for earning our livelihood, and for allaying the sufferings of mankind desirous of health. Earthly and heavenly bliss depends upon it. Hence, Sire, we have come to you to become your pupils.' " To them said the venerable man : ' Ye are welcome. All of you, my lads, shall be taught and made to meditate. Ayur-Veda is an Upanga of the Atharva-Veda. The Self-born, after creating the universe, com- posed it in a thousand chapters, containing a hundred thousand verses. But, knowing the brevity of human life and the limitedness of human understanding, he reduced it to eight divisions. These are : 1.

Ayur-Veda is so called hecaiise Ijy it health is gained or it hrin', which he did not complete, although he lived until about 1318. This treatise, of which several manuscripts exist, was finally edited and printed by Dr. Julius Leopold Pagel of Berlin in 1892, forming an octavo volume of 660 pages having the title of Die Chinoyir (h\<^ Heinrich von Mondeville {Hennondaville), etc., and has been translated into French and published in 1893 by Professor Nicaise of the Faculty of Medicine of Paris. His practice is much the same as that of Lanfranc, and of his successor, Guy de Chauliac, who often quotes him. He describes the method of ligating a wounded artery, recommending a peculiar kind of slipknot, but says nothing of ligating the vessel in amputations, and refers to the use of the ansesthetic sponge described by Guy. Here may also be mentioned the Surgery of Master Jean Yperman, a native of Flanders, who was born in the latter part of the thirteenth century and studied under Lanfranc in Paris. The manuscript of his book, dated 1351, Ayas first described, and in part published, by Dr. Carolus in the Annales de la Sociefe de Medecine de Gand (vol. xxxii. THE HISTORY ASD LITERATURE OF SVRGERY. 41 1854) ; also jniblished separately as a re])rint. He refers to Roger and Roland and the Four Masters, and frequently to Lanfranc, beyond \vh(ise teaehings he seldom ventures to go, although he does give some cases of his own. The great French surgical author of the fourteenth century was Gui (or, as it is more usually given, Guy) de Chauliac, " Guido de Chauliaco," born aliout 1300 A. D. He received the university training of the cler- ical profession and studied medicine at Paris, after wliich he continued this study at Montpellier and Bologna, so that he had tlie lienelit of the three greatest universities of that time — Paris being especially celebrated for its surgery after Lanfranc had reached it ; Montpellier being the centre for medicine ; and Bologna for anatomy, of which Bertrucius was then professor. After extensive travels, and practice in different places, including Lyons and Montpellier, he ^\•ent to Avignon and became the physician of Pope Clement VI. and of liis successors. Innocent VI. and Urban V. His chief literary work was liis Chinur/in, written at Avi- gnon in 1363, and first published at Lyons by Nicholas Panis in 1478. The " Great Surgery " begins with a special introductory chapter, the chapilrc singuUer. He says : " Up to the time of Avicenna all writers were both physicians and surgeons (/. e. well-educated men), but since that time, either because of the fastidiousness or the excessive occupation of the clerics, surgery has become a separate branch and has fallen into the hands of the mechanics. " The sects which have existed in my time among the operators of this art, besides the two general ones of the Logicians and the Empirics, have l)een five. " The first was the school of Roger, Roland, and the Four Masters, who treat all wounds and abscesses alike with cataplasms and poultices, on the ground of the fifth aphorism, ' Lax things are good, and crude bad.' " The second was the school of Bruno and Theodoric, which treated all wounds alike with wine, basing their practice exclusively upon the maxim, ' The dry is nearest to that which is sound, and the moist to that which is not sound.' " The third sect was that of William of Salicet and of Lanfranc, who wished to pursue the middle course, covering and dressing all wounds with ointments and soft plasters, founding this practice on the fourteenth maxim of the Therapeutics — that curation has one sole method ; tliat the treatment should be gentle and without pain. " The fourth sect is composed of all the military men, or German chevaliers and others following the army, who, with conjurations and potions, oil, wool, and cabbage-leaves, dress all wounds, basing their practice on the maxim that God has given his virtue to herbs and to stones. " The fifth sect is of women and of many fools, who refer the sick of all diseases to the saints solely, saying, ' Le Seigneur me I'a donnee ainsi qu'il luy a plfl ; le Seigneur me I'ostera quand il luy plaira ; le noni du Seigneur soit benit. Amen.' " It will be seen that Guy is quite trenchant in his summaries and crit- icisms, which, however, appear to be on tlie whole fair and justifialile. The teachings of Guy were the chief authority in surgical matters 42 THE HISTORY AXD LITERATURE OE SURGERY. for over two litiiulri'd years, iuul wcri' tl:i' basis df iHiiiicrous abstracts, odinpemls, and commentaries. He contributed little that was orij^inal, although he gives some of his own observations. Follin remarks that a sort of canulated sound, the dressing of ulc^ers with sheet lead, and some jM'culiarly-shajx'd cauteries are his chief inventions ; l)ut his book is one of the monuments of surgical literature. The tSermo ■■^cjitiiiiiis dc cyruryla et dc dn'orafionc of Nicholas Faleu- tiiis, of which the Washington Library has an edition printed at Florence in 1507, is a huge folio volume compiled from the works of Arab writers, with references to Roger and Roland, but not to Guy de Chauliac, so far as I have found. His formula of words is " Dixit Haly," or " Avicen," or "Albucasis," witliout attempt at conuneiit. In the days of J^anfranc and (tuv de Chauliac surgery in AVestcrn Europe was distinct from medicine, and was looked upon as a trade or handicraft degrading to and unworthy of physicians, who claimed to belong to the nobility. The physicians \vere of the priestly class and abhorred the shedding of blood, and their traditions were adhered to long after medical teaching in the universities had passed into the hands of laymen. The barl)erswerc the ordinary surgical operators, and the reason for this is given by Dr. Gardner ' as follows : " The monks, as all the Avorld knows, recpxired to have their heads regularly shaved, but it is not by any means so well known that they had to be bled at stated ]icriods. 3Iinu(u>i ed was the form of words descriptive of one who had undergone the operation, the meaning being that he had been minntus xidu/uine — i. e. deprived of blood. In the monastery of St. Victor at Paris there was an order which prescribed such minution five times a year : ' Prima, est Scptembri ; secunda, ante Adventum ; tertia, ante Quadrigesimum ; quarta, post Pascha ; quinta, post Pentacosta.' The monks, therefore, required to have about them those mIio could lioth shave and bleed, and it was very natural that they should prefer that one antl the smne person should ])erform both these operations." In France, however, at an early date there were a few persons whose business was the performance of surgical operations, and who were not ordinary barbers, although they may have served an ajiprenticeship as such. The Cor]ioration of Barbt'rs in the middle of the thirteenth cen- tury was divided into two classes — the ordinary or lay barbers, afterward known as "barber surgeons" or "surgeons of the short robe," and the " clerk barbers " or " surgeon barbers," " the surgeons of St. Come," or " surgeons of the long robe ; " and these last sought to be independent of the ordinary barbers, to monopolize surgical operations, and to raise their association from the position of a trade guild to that of a profes- sional oryanization. The Guild of the Snry-eon Barbers was organized in 1268 by an order of the provost of Paris, selecting six surgeons who were to examine and license those who wished to practise, more esjiecially the barbers. Possibly one of these masters was the celebrated Jean Pitard, but if so he must have been very young, for he was still living in 1326. In 1311, Pitard obtained a decree from King Phili]) the Fair, in which, after reciting that all sorts of quacks are infesting the city, it is ordered that " no male or female shall practise surgery in Paris who has not been ^ Gardner (John) : Sketch of the Early Ilislonj of the Medical Profession in Edinburgh, Edinb., 1864, p. 6. THE HISTORY AND LITERATURE OF SURGERY. 43 exaniinod liy our sworn surgeons of Paris named and called togetlior for tliat purpose by Jean Pitard, our sworn surgeon of the C'liiitelet, or his successors." It was evidently impossible to enforce this order, for it was repeated in 1352, and again in 1364, with penalties of Hues on the erring barbers, half of the fines to go to the surgeons' guild, the Brotherhood of 8t. Come. The organization of tiiis brotherhood was by no means pleasing to the medical faculty, the memljcrs of which desired to retain control of all branches of the art, and discredited surgery as a mere mechanical handi- craft only to be exercised under the direction of a physician, whose dig- nity forbade him to soil his hands. The statutes of the facidty in 1360 recpiirc the candidates to make oath that they will not practise surgeiy in the sense of performing operations or' making applications by the hands, including the treatment of five classes of affections — viz. wounds, ulcers, fractures, dislocations, and tumors. The lay barbers were employed by the physicians, and also sometimes as assistants by the surgeons, and at last, in 1372, the barber of the king, being the master of the guild of barbers by virtue of his position, induced Charles V. to issue an edict which permitted them to treat wounds 'and sores and forbade the surgeons to interfere \vith them. The relative standing in the eyes of the public of the three kinds of practitioners — viz. the physicians, the surgeons, and the barbers — may be inferred from an order issued during an epidemic of the pest in 1383, which directed that there shall be selected to visit the sick four physicians, two sur- geons, and six barbers, and the fees of tii(^ doctors shall be three hundred livres, of the surgeons one lunidred and twenty livres, and of the barbers eighty livres. The so-called College of Surgeons of Paris was not in the least a surgical school or an association for mutual discussion and improvement : it was })urely a trade guild, and the students were simply apprentices to the master surgeons, becoming, after 1370, bachelors, licentiates, and finally masters. The surgeons had a free dispensary, where they treated the poor once a week, and perhaps the apprentices saw there something of the jtractice of other masters besides their own. The medical faculty, thinking that its rights, privileges, and monopoly of treating the sick were being encroached upon by the surgeons, encouraged the barbers in their controversies, and as one means of doing this undertook to teach them anatomy. As the barbers did not understand Latin, which was the only dignified and proper language to be used in teaching in those days, a compromise was necessary, and this was effected partly by the use of a sort of dog-Latin, of French words with I^atin terminations, and partly by reading Guy de Chauliac in Ijatin, but with comments in French, wiiile the assistant barber made tlu' incisions in the cadaver and pointed out the ])arts as tiie reader named them. In 1505 the bai'bers came moi-e formally under the protection and jurisdiction of the faculty, and assumed the name of the Guild of the Barber Surgeons, and a few years later the surgeons of the long robe, having opposed this movement with very little success, and luu'ing failed to become a separate faculty in the university, submitted to also receive instructions from the physicians. Almost all the medical officers attached to the French armies came from tlie Corporation of Barber 44 THE HISTORY AND LITERATURE OF SURGERY.

Nevertheless, he was a ])artisan of the aneients, and two of iiis sayings have l)econie historical as illustrating the university sjjirit of tile age— viz. " It is more honorable to err with (Jalen and Avicenna tiian to at'cjuire glory with others ;" and, " It is better to die l)y a regular j)hysieian than to live by a quack." One of the most celebrated Italian surgeons of the sixteenth century was Gaspar Tagliacozzi, l)etter known as Tagliaeotius (.1546-09), who was professor of anatomy and surgery in tiic University of Bologna, and wrote tlie hrst special ti'eatise on ])lastie surgery, and more particularly on the o])eratiou of rhinoplasty, with which his name is especiall)' asso- ciated. The title of his book is De Curtorum Chirurgia per insiiionem, libri duo, of which two editions wei'e published at Venice in 1597. One of these, a large folio jiulilished by Ga.sjiar Bindonus, is celebrated for the beauty of its plates,- the quality of the paper, and its typography, being a splendid specimen of book-making ; the other edition of the same date and place, jiublished by Robert Meiettus, is also a folio, but a much poorer specimen of the printer's and engraver's art. There is also a small octavo edition of Frankfort (1598), and one was published in Berlin so late as 18.'U. He does not name the iierson from whom he had learned his method, but it was probably from some one of the Inc-isors of his day who had ac([uired his knowledge from a jnipil of one of the Sicilian Brancas, who were celebrated for operations of this kind in the middle of the fifteenth century. The elder Branca took his flaps for a new nose from the skin of the face, being the Indian method ; his son made use of the skin of the arm, and extended the method to repair of nuitilated lips and ears, as we are informed by Bartholomeo Fazia. The first notice of Tagliacozzi's method is givi'n by H. Mercurialis in his Dc decorafione liber (4°, Venet., 1585, fol. 23). Two of his pupils describe the methods and the results obtained, and acquired repute by their performance of the operation — viz. Thomas Fienus of Antwerp, and Jo. Bapt. Cortesius, who succeeded Tagliacozzi as pro- fessor at Bologna ; but the practice fell into disuse among surgeons, and little was heard of it until the beginning of the nineteenth century. A curious use of plastic surgery is mentioned by Fortunatus Licetus — viz. the making of double mon.sters for show purposes by grafting two boys together by the back, nates, or arms, upon which he says : " Aver- runcct Deus e severe puniant principes tales sicophantes." Victor Hugo refers to the work of these " monster-makers" in his L' Homme (jni rit. Marianus Sanctus Barolitanus (1490-154?), a native of Naples and a special pupil of John de Vigo, wrote a treatise entitled Compendium in Chyrurgia Utilissimum Volentibuti ipsas exercere, which was first pub- lished at Rome in 1516, and subsequently appeared in connection with the works of De Vigo. It is also in the Gesner Collection of 1555. Neither Haller nor Malgaigne knew the date of the first edition, which is jirobablv rare. The copy in the Washington Libi'ai'v is a small quarto of fifty leaves, unnuml)ered and unpaged, and is a fine specimen of black- letter printing. It contains three small rude figures of cauterizing irons, and the last nine pages are occupied with his Traetatus de Capite. Mari- THE HISTORY ASD LITERATURE OF SURGERY. 47 anus Sanctus is best known by his treatise Dc LaphJc c.v resica per iiicis- ionem e.vtrahenda, in which was, tor the tirst time, pulilished the method of John de Romanes for lithotomy with a grooved staff, upon which an incision was made into the membranous portion of the urethra, after Mhich instruments were introduced to dihite or rupture tlie prostatic portion. This is ivnown as " the metliod ^vith the great apparatus," from the num- ber of instruments required, and also as the " Marian operation," from the name of the person ^\•\\o tirst pul)lished the description. The first edition of this treatise appeared at Venice in 1535. It is contained in the Gesner Collection of 1555 and in Uflenbach's Thesaurus of 1610. The " Gesner Collection," also known as the " Geneva Collection," is a beautifully printed folio with the title Chiruryin. De chirurf/ia licriptoreti optiini < & autres e.rcellentes parties de la chirurgie, assavoir de la pierre, des cataractes des yeux, & autres maladies, desquelles comme la cure est perilleuse, aussi est elle de peu d'hommes bien excrcee. This is a small octavo of 16 preliminary leaves, 554 pages, and 1 leaf of errata. It contains all the matter of the preceding book, and much more, with figures of new instruments, and is really a small manual of surgery. The part relating to lithotomy remains substantially the same. Next to the works of Pare, this is the most valuable contribution of the century to surgical literature. The history of the Colot famil}' is curious and interesting, but is wrongly given by most of the biographers : the best is that given by Dr. E. "Turner in the Gaz. Hebd. de MM. et de Chir. (Paris, 1880, xvii. 2' ser. pp. 33, 49). The story that a certain Germain Colot, a French surgeon, learned the details of the methods of some of the Incisors about 1460, and then, returning to Paris, operated on an archer who had been condemned to be hung, but whose sentence was changed by the king to be operated on by Coli>t, is probably without foundation. The original account, given in the Chronique scandaleuse, does not mention the name of the operator, and Malgaigne says that there is not even a presumption that there ever was a surgeon named Germain Colot. There was, however, a Laurent Colot or Collot, who lived at Tresnel, near Troyes, in the middle of the sixteenth century, and who learned the method of John de Romanes — or what is called the IMarian opera- tion — from an itinerant lithotomist named Octavien da Villa. He kept the method a secret and had great success, being called to Paris in 1556, and was appointed lithotomist of the Hotel Dieu. The secret and the THE HISTORY AND LITERATURE OF SURGERY. 49 office remaiiK'fl in the family, the grandson Piiilijjpe (1593-1650) lieing called to all parts of Europe to operate. His son Fran(,-ois (1630-1706) wrote an aeeount of the niethoil, which was published after his death under the title Traitii dc rope rat ion de la taillr, etc. (Paris, 1727). In it he refers to the above-mentioned story about Germain C'ohrt, but does not give his name, and asserts tiiat the operation ])erformed on the archer was a nephrotomy and not a lithotomy. That the so-called family secret could have been preserved until the beginning of the eighteenth century, after the publication of the method by Marianus Sanctus in 1535 and by Franco in 1556, illustrates tlie education of the surgeons of those days. We now come to an epoch-making surgeon, Ambrose Pare (1517-90), who was apprenticed to a provincial barl>er when he was about nine years old. In 1532 he came to Paris, where he was probably again ap- prenticed to a barber surgeon and attended the lectures of the doctor of the Faculty of Medicine of Paris, whose business it was to explain to the voung Ijarber surgeons those parts of the surgery of Guy de Chauliac which relate to tumors, wounds, and ulcers. Very soon after his arrival at Paris he had the good fortune to obtain a position as resident a})pren- tice and dresser in the great hospital of the Hotel Dieu. Here he had opportunities for dissections, for making post-mortem examinations, and for the study of disease, of which he was not slow to avail himself. In his preface to the reader he says : " You must know that for the space of tliree j-ears I have lived in the Hotel Dieu of Paris, where I had the means of seeing and knowing (in consequence of the great variety of diseases brought there) all which can be of alteraticm and disease in the human body, and to learn from an infinite number of dead all that can be said of anatomy." At the end of this service, when he was but nineteen years old, he became body-surgeon to Mareschal Monte Jan, and went with him in the army which Francis I. opposed to that of Charles V. in the invasion of Provence in 1536. Gunshot wounds were supposed to be poisoned, and the recognized means of destroying the venom was that prescribed by John de Vigo — namely, cauterization by boiling oil. But in one battle the supply of oil was insufficient, and our conscientious youth could not sleep that night for thinking of the horril)le fate that was in store for the poor fellows who had not been cauterized, (jreat was his astonishment and delight the next day on finding that those who had not been burnt were much more comfortable than those who had been treated sceundam artem, and that recovery was prompter and more certain in their case. But, while Pare had the sense and the independence to refuse to give unnecessary pain, although commanded to do so by the highest surgical authority of his day, he could not free himself from the notion that some special treatment was recpiired for gunshot wounds, nor accept the plain teaching of his own experience. He decided that the best thing to be done was to use a secret remedy which- was the stock in trade of a certain surgeon in Turin, and to learn the composition of this remedy he assidu- ously courted the good graces of this surgeon for over two vears and a half, and finally obtained the se(>ret for a round price, ])romising not to divulge it. It was an oil of ])uppies, not much different from lard— a simple protecting soothing application. No sooner had Pare learned the secret than he hastened to publish it, deliberately breaking his promise Vol. I.— t 50 Tllf': HISTORY AXI) LITERATURE OF SURGERY. on the crniind tliat siioli nn important matter should not be one man's priviletic The areat ini])rovem(iit made l)y Pare in snrti^erv was the use of" the ligature to close bleeding arteries after amputation in place of scaring them with red-hot irons, as had been done down to his time. In the edition of his works published in 15(34, Dix Hvreft ck Chlni/r/ic, he first describes and recommends the application of a ligature to lilccd- ing vessels in amputations, and abandons the use of the cauteiy. His account is as follows: After alluding to the j)assage in Galen which states that "the vessels must be tied toward their roots, which are the liver and the heart, to staunch the great flow of blood," he says : " But having many times used this means of closing the veins and arteries in recent wounds where there was a hemorrhage, I thought it might also be done in amputating a member. Therefore, having conferred with Esti- ennc de la Iviviere and Francois Kasse, both surgeons at Paris" [in later editions the name of Rasse is struck out and in place is read " other sworn surgeons of Paris "], " we agreed that we would make the trial upon the first patient which offered, although we would have the cau- teries all ready to use if the ligature failed." A few days afterward the ligature was applied with success in a case of amputation of the leg. Pare was a good anatomist, by far tlie greatest surgeon of his time, the confidential friend of four successive kings, and is said to have been the only Protestant in I'aris v.\w was spared the massacre of St. Bar- tholomew, which was due to the direct action of the king. Malgaigne's argument against the truth of this story cannot outweigh the direct state- ments of Sully and of Brantome. Catherine de Medici one day asked Pare whether he hoped to be saved in the next world. " Yes, certcs, madame," said he, " because I do what I can to be a brave man in this world, and because the mercifid God understands all languages, and is as well satisfied with a French prayer as with a Latin one." To properly appreciate the \\ritings of Pare, they should be compai'ed with those of other teachers of, or writers on, surgery of his day. His treatise upon gunshot wounds may be compared with several small trea- tises on surgery pul)lished in the latter half of the century, thirty or forty years after the appearance of his treatise on this subject, and written in French for the benefit of the barber surgeons. Take, for example, the Traitte des arcbumdes of Joubert, published at Lyons in 1574. Laurens Joubert (1529-83) was a distinguished physician of Mont])ellier, ]>ro- fessor of medicine in the university and dean of the faculty. He had served in the royal army in the campaign of 1569, where he ought to have heard something of Pare's methods of treatment, but he makes no allu- sion to them, unless it be where he speaks of the oil of puppies as an anodyne. His Surgery is that of John de Vigo, written in a diffuse, pedantic style, which was probably impressive to the barbers in jiropor- tion to their inability to understand the meaning of his words. At one time he was called in as an uni))ire in an argument between a physician (Veyras) and the surgeon of the king of Navarre (Guilhemct) as to whether gunshot wounds are contused and should be treated by poultices, etc. or by desiccatives, as by washing with wine. The arguments on both sides and Joubert's decision were published in a curious little book THE HISTORY AND LITERATURE OF SURGERY. 51 entitled Tracite dv Vhiinirgie, contcnant i-raye methode de r/ucrir plai/es d\irquebumde, etc., par ]M. Jaeqiies Vtyras, docteur en Medecine, & M. Tannequin Guilhemet, Chirurgien du Eoy de Navarre (Lyon, 1581, 8°). Jonbert's decision was, upon the whole, in favor of the views of the plu'sician, as was to be expected. He refers to Pare as " homme digne foy," not with reference to his treatment of wounds, but to his statement that bones may be fractured by the wind of a cannon-ljall — this lieiug precisely one of the points on which Pare was wrong. The lirst teaching in French given to the barbers and surgeons was by a physician, Jean Canape of Lyons, physician of Francis I., who in the first half of the century gave public lectures to them, and for the same purpose translated into French a compend by Guy de Chauliac (Lyons, 1538, 12° ; also 1563-71), some anatomical treatises of Galen (Lyons, 1541), and several other small treatises. Pierre Tolet (1502-8?), a surgeon of Lyons, in 1540 published a translation into French of the sixth Book of Paulus ^gineta. In his prefatory letter to this, addressed to the French surgeons, he refers to Jean Canape as a man to whom surgery owes more than to any man who has written since (Jalen. In 1570, .Taeipies Dalechamps, pliysician and reader in surgery at Lyons, published Vhlrurgie Framjoise as a manual for the barber sur- geons. It consists of the sixth book of Paul of ^Egina, Hippocrates on fractures and dislocations, and extracts from Celsus, Albucasis, etc., witii the annotations of Dalecliamps, and a brief treatise on operations by Jean Girault, master surgeon in Paris. In 1583, Esaie le Lievre, surgeon, published a little book entitled Ojfieinne et Jurdin de Chirurc/ie mUitaire contenant les instrumentz et pinnies tves necessaires a tous Chinur/ieiw, etc. The general style of this work may be seen in the following sentence : " Nous disons I'har- quebnzade on jilaye faicte par harqucbuze ou canom ; estre une aiFection contrc nature, portant de foy plusienrs especes d'accidens ; a scavoir extreme contusion, combustion, diruption, dilaceratio, concution, frac- tion, fracation, j)uis repercution, abolitions, destructions, extinctions, ou mortifications, selon plus ou moings, des espritz tant vitaux, animaux, que naturels : de laquelle complication assemblee, selon la nature tt noblesse des parties offensees, se forme une indisjiosition tendant a reudre ladite partie, consequement tout le subiect en cadaver." The Sclopetarim of Quereetanus (Du Chesne) (Lyon, 1576) is a wortliless book by a notorious charlatan. It was translated into Eng- lish and published at London in 1590 by a certain John Hester, who offered for sale the Arcana prescribed therein. Care is taken to give two sets of remedies — one for the injuries of the common soldiers, the other " to be used for the rich." For advertising purposes the same John Hester published .1 .S7(o/-/ TH.^cmirs of the e.rccUent Doctour and Kiiif/lit, ma'ifiter Leonardo Fhiorcircuiti, Bolognese, uppoii Chirurgerie (London, 1580), advertising at the end that he is pi'epared to furnish various salves, philosoj)hical oils, and other preparations recommended in it. Phioravanti explains that "the reason why white of egg is to be used in mixing ajiplications for wounds is because the white is that ])art which produces the flesh, the skin, and the feathers of the hen, while the yolk engendereth only the intestines. Therefore the white is like 62 THE THSTORY AND LITERATURE OF SURGERY. unto flcsli, aiKl its special business is to produce it." He says also that the most perfect remedy for a great flux of blood from a wound is to stitcli it close, and then take dry human blood-[)o\\dcr and lay it upon the wound. This is tiie same as the mummy of I'aracelsus. Tiic reference made by Pare as to the value of the instruction whicli he obtained in the Hotel Dieu is perhaps the tirst allusion to the imi)urt- anee of hospitals as a means of furnishing instruction in surgery. Hos- pitals had existed since before the Christian era in India, and those in Persia under the Nestorians were really used for educational purposes in connection with their medical schools. The foundations of many European hospices and hosjiitals date from the tenth and twelfth cen- turies, such, for example, as the San Spirito at Rome and St. Bartholo- mew's and St. Thomas's in London, some of the impulse to the forming of such institutions apparently having come from the need of providing them for lejiers. No surgical instruction appears to have been given in the hospitals of the Middle Ages, exccjit that the surgeons connected witii them may have employed some of their apprentices to assist them in the bandaging and in the dressing of wounds ; but what we know as " clinical surgery " was an aifair of nuich later date. Of the immediate j)upils and followers of Pare, the most important were Pierre Pigray (15o.j-161.j), whose published works are mainly abstracts and translations of Pare; and Jacques Guillemeau (1550-1012), surgeon of Charles IX., Henry III., and Henry IV., and surgeon of the Hotel Dieu, who accjuired tame as a writer and teacher in surgery, obstetrics, and ophthalmology. His La chirurgic fmnqolse (Paris, 1594, folio) was translated into Dutch, and thence into English, and published at Dort in lo!t7 under the title of The French < 'hin(r(/ci-ifc, i'orimng a, beautifully printed and illustrated foliii, winch was much the best work on this subject which had then appeared in English. Guillemeau Avas unusually well educated for a surgeon of those days, having studied under Riolan as well as under Pare, and he tried to harmonize the statements of the latter and those of his op])onent, Gourmelin, by saying that Galen recommends the cautery in amputation for gangrene, and aji- proves the use of the ligature for hemorrhage when there is no corruption. Par4 in advising the ajiplication of the ligature says it does not matter if some other tissue besides the vessel is included in it ; but Guillemeau says that a portion of such tissue is to be included : " prenant quelquc portion de chair ensemble," evidently thinking that this is an important feature of the o})eration. His chapter on aneurism contains an account of a case of traumatic aneurism at the bend of the elbow in which he applied a single ligature above the swelling M'ith success. In this case the aneurism had ruptured, and after ligating the artery he opened it further and turned out the clots. This one ligature A\as j)laced three fingers'-breadth aliove the tumor. Park's description of the operation also refers to the use of but one ligature, and not to tlie operation of Antyllus. There were no surgeons of repute in Germany prior to the middle of the fifteenth century ; they were almost all barbers, who could neither read nor write. In 1868 there Avas for the first time pub- lished a manuscript treatise on surgery Avritten in German about 1460 THE HISTORY AND LITERATURE OF SURGERY. 53 by Hc'inricli Pfolzju-iuidt, and entitled BiiinHh-Ertznei. This, the oldest German work on surgery at present known, relates mainly to the treat- ment of wounds, but it contains a remarkable chapter on the making of a new nose from the skin of the arm after the method of Branca. There is an allusion to the burning t)f wounds by powder, but no refer- ence is made to lithotomy or to operations for hernia. It gives a receipt for a narcotic mixture to be inhaled from a sponge similar to that men- tioned by Guy de Chaidiac. The first German surgeons of repute whose works have come down to us are Hieronymus Bnmschwig, and Hans von Gersdorff, called Schylhans or Schieliians, both being surgeons at Straslinrg in the last half of the fifteenth century. Erunschwig was born about the middle of the fifteenth century, and published at Stras- burg in 1497 a folio volume with the title Din id da-s biwh dcr Viruryki, Ilmdwirck der Wundartzny von Hyeronimo brunschwig. Of this there were eight other editions, the last at Augsburg (1539, quarto). The Washington Library has the folio editions of 1508 and 1513 and the quarto editions of 1533 and 1539 ; also the English translation of 1525, and a Dutch translation in folio printed at Utrecht in 1535. The Eng- lish translation is the first book on surgery in English, and its title-page is a curiosity in itself. It begins as follows : " The noble experyence of the vertuons handywarke of surgeri prac- tysyd & compyled by the nioost expertc ]Mayster Jherome of Bruyns- wyke borne in Stracsborowe in Almayne yi' whiciie hath it fyrst proved and trewly foiuide by his awnc dayly exercysynge." This title is the work of the unknown translator, who has also given a short })rcfaci', in which he siiys that "it is oftentymes sene and dayly chaunceth in small townes, borowghs and villages that dyverse people hurt or dyseased for lacke of connynge men be taken in hande of them tliat lie barbers or yonge maisters to whome this sciens was never dys- closed, not thynkynge on the wordes of the olde lernyd men that say, It is not wel possible to man that he sholde bryngt' well to a good end the thynge wliiche ho never or hath but lytell seen." Brunschwig's book was the first in which any definite statement is made about gunshot wounds, or, as the English translation has it, " of woundis sliot with a gone whereas the venym of the powder abydyth in." To remove the venom he advises to pass a small cord of hair through the wound and draw it back and forth, after which a tent is to lie placed in the womid. In amputation he advises either the actual cautery or boiling oil to cheek hemorrhage. He has nothing to say about lithotomy, herniotomy, aneurism, or tumors — the book biMug, in fact, a treatise on the military surgery of those days. It is illustrated with large quaint wood-cuts which are anifiiig the earliest sjiecimens of the art. Haeser says there were two English translations — one published at London, and the other at Soutliwark, but these are the same work. Hans von Gersdorff was an army surgeon in 1476-77, and published his book, Fcldthuch der Wundtarzucfi (in folio), at Strasburg in 1517. Of this there were eight later editions and translations into Latin and Dutch. The Washington Lil)rarv contains the first edition, and also the Strasliurg editions of 1527 and 1540 and the Erankfort edition of 1551. Gersdorll" treats more fully of shot-wounds than docs Brunschwig. 54 THE HISTORY ANT) LITERATURE OF SURGERY. He docs not consider them to be poisonous, but gives detailed directions for findiiiu' and extracting the bullet, with figures of instruments, and advises tliat tiie powder be removed, after wliieh warm linseed oil is to be poured int() the wound. He says: " I do not know of any l^etter or milder remedy than this, which 1 have learned from Master Nicolaus, called the Maulartzt, surgeon to Duke Sigmund of Austria." If ampu- tation becomes necessary, he says : " First of all advise the jiatient to resign himself to God, to confess his sins, to remember the suffering of our Lord witli thanks, and the surgeon the same ; tJuis will God grant him good foi'tune in his work. And when you will cut him have ready by each other all your instruments and ap])aratus, such as scissors, knife, saw, styptics, bands (lassbendel), bandages, pads, tow, eggs, and what belongs to it, so that one follows the other in the order of the operation, since there is need of this. And when you are ready to cut let some one draw back the skin strongly and tie a band firmly around it, and place another band in front so tliat a space of a finger-breadth be left between the two bands that you may cut between them with tiie knife ; then this cut is quite sui'e, easily made and makes a good stump. When j'on have made the cut take a saw and divide the bone, and then remove the band and tell some one to draw the skin over the Ijone and flesh and hold it tight in front ; and you should have a bandage two fingers limad and well wetted that it may lie smooth, and witli it bandage the thigh down to the cut that the flesh may go in front of the bone, and leave it thus bound. And you need not fear bleeding if you have done as above described. Bind now over the styptic a good thick pad, take the bladder of a bull, ox, or hog, one which is strong, cut the neck open so that it will go over the pad and stumj), and the bladder should be wet but not too soft ; draw it tlien over all, tie it hard with a band and you need have no care about the bleeding." The following is the styptic referred to : " Take of unslacked lime two ounces, vitriol, alum, each, one ounce, of aloes to be calcined, gall- nuts, colophony each a quarter of an ounce ; of the residuum in the retort when you make aquafortis two and a half ounces, and the white hair of the belly of a hare or deer chopped up, and mix all together thoroughly. When you use it mix it with white of eggs But if an artery rages and will not be staunched then burn it with a cautery." Although he used no ligature in am]iutation, he does advise a double ligature on a wounded blood-vessel. He has a chapter on leprosy, but says nothing definite about syphilis. The plates in Gersdortf 's book are especially interesting. Walter Hermann Ryif was also a Strasburg surgeon of the first part of the sixteenth century, and published a number of treatises in German, his Gross Ckirurgci appearing in 1545, and his Kleiner C'hirurr/i in 1551. This tendency to depart from scholastic methods received a strong impulse from the sayings, doings, and writings of Philippe Aureole Theophrastus Bombastes de Hohenlieini, lietter known as Paracelsus (1493-1541). He was born in the village of Einsiedeln, near Zurich, studied medicine with his father, travelled extensively, studied chemistry and alchemy \\ith Sigismund Fugger, and served as an army surgeon in eam]>aigns in Italy and the Netherlands. Of unbounded self-assurance and ha\ ing a knowledge of some new rcme- THE HISTORY AND LITERATURE OF SURGERY. 55 dies, such as antimony, arsenic, and mercury, he soon acquired a great reputation, and in 1526 was appointed professor of medicine in the University of Basle. He is eliaraeterized by Dalton as "a rampant, blatant, boasting, ignorant vagalionil, with a face of bi'ass and a tongue like a race-horse," and, if the word " ignorant " be omitted, it is a true picture. But he \v"as also a sort of genius, in a way a poet ; and, knave and charlatan, and in his latter days drnidvard, though he was, his doctrines were accepted by such men as Frobenius, Erasmus, and Van Helmont, anil had a powerful influence throughout Europe for a century or more, some of his pecidiar theories still surviving as the essence of modern homceopathy. He wrote or dictated many works, of which the only one that need be mentioned here is Der grotmen Wundartzney (15.36-37), of which there were several editions, besides Latin and French transla- tions. The second chapter begins as follows : " It is necessary to know in the first place what is the efficient cause of the curing of wounds, because this may of itself indicate the proper treatment. Know then that the human body contains in itself its own proper radical lialsam, born in it, and with it, and not only the body as a \vhole contains it, but all its parts, such as flesh, bones and nerves, have each its own peculiar juice competent to cure wounds It is not the surgeon who cures wounds, it is the natural balsam (or juice) in the part itself." Hence he inveighs against what he calls " the damnable precept which teaches that it is necessary to make wounds suppurate." Elsewhere he calls this animal juiee " la mumie," but he also meant by this a special preparation made from certain parts of the human body — something like the animal juices and extracts whicli have been re- cently recommended as remedies, and which are quite Paracelsian in character. The ideas of Paracelsus were accepted by Felix Wurtz (1514-74) of Basle, who studied under Ryft' at Nureml)erg, and was on terms of inti- macy with Paracelsus and with Conrad Gesner, the most learned man of his time. He acquired great reputation, and published his Practka (ler Wauflarziiet/ in 1563. Of this about fifteen editions appeared during the next hundred years, including an Euglisli translation by Fox, pub- lished in 1656. He remarks that "skill in surgery is obtained with great painfulness, for it is not gotten witii sitting on a cushion at home and by reading and writing ; .... it is not enough to be full of talk, and to say such and such and write so and so, — a patient is little the better for it if the surgeon hath no skill to dress his wounds." The work is almost entirely devoted to wounds and fractures and their consequences, and contains nothing as to the teehni(]ue of surgical operations. The treatment advocated is in the main sinqjle and sensible. Styptic powders are condemned fi)r general use, as is also the cautery to suppress hemor- rhage, except in amputation of the thigh. No allusion is made to the ligature, and it is not probable that he had ever seen the works of Pare. He objects to the probing of wounds, declaring tiiat it is filly to feel and grope about them, and tliat some surgeons use the ]n'obe merely because tiuy have seen it used and to show that they are doing something. Cat- aplasms and poultices for fresh wounds are condemned, and the blood is not to be washed or squeezed out, " for it is a right flesh glue and hasteneth the healinar." He often refers to the conservative surgeons 56 THE HISTORY AND LITERATURE OF SURGERY. who say, "Old customs should not be abandoned," and says, " ThcrcCore in sonic places the books of 'J'lieophrastus Paracelsus (to whom the best and most fiuiious sur};-eons must give place) ai'c prohibited to be read ; but in my simple judgment it is done vi'iy tbolishly." He objects to drawing a cord through a gunshot wound, or to using hot oil, or to treating such injuries otherwise than as simple wounds. The third part of his book, being on the symptoms and complications of wounds, including a description of the wound-fever or pyaemia, is the most original and valuable part of the work. The instruction of the barber surgeons' apprentices at the end of the sixteenth century appears to have been based on the views of Jerome of Brunswick, if we may judge from a little manual by Julius Holder, pub- lished at Frankfort in 1592, entitled DialoguH, em Niltzliche niicl Warh- (iff'tif/c Bcurlircihinu) dnes rcchtc Wundiniztti mind seiner Jleixferschtiff. This is in the form of ijuestions and answers, Latin terms being curiously intermixed with the (rerman. Another good specimen of the sort of instruction given to apprentices of German barber surgeons in the sixteenth century is the Wundartzney zu alien gebrechen des gantzen Leibs, etc. of Joannes Charethanus (or C'liaretanns), of which five editions appeared between 1530 and 155'5. The edition of 15411, printed at Frankfort, is a small quarto of 20 leaves, giving directions for Itloodletting and tootli-pulling, and various formula for salves and potions. It directs that wounds should be dressed twice a day; that he who i.s wounded in the head shall not walk about or move much ; that he shall avoid perspiring and talking, which inflame or disturb the brain and make him insensible ; above all, he shall avoid strong wine, which ])uts him in deadly peril; likewise the rays of the sun and light and heat and indigestiljle meat and the society of woman, whom he shall not even look upon. If a large ai'tery is cut or opened, first secure the same carefully with a silk thread to stop the bleeding ; then lay on the red powder and cover with a red plaster. Let it remain for four days and heal it like other wounds. The Seventeenth Century. The seventeenth century is more remarkable for the advances which were made in jihysics and in physiology than it is for improvements in surgery. It was the age of Francis Bacon (1561-l<)2(j), of (Jalileo (15(54— 1642), of Rene Descartes (1596-1650), of Pascal (1623-62), of Sir Isaac Newton (1642-1727), and of Robert Boyle (1626-91), all of whom had a powerful influence in developing the iatro-chemical and iatro-mechan- ical theories which prevailed about the end of the ccnturv. This was also the ago of Borelli (1608-79), of Thomas Sydenham (1624-89), and, above all, of William Harvey (1578-1657), the pupil of Fabricius d'Aquapendente, whose celebrated work, E.rercitatio Andtoniica de Jlofu Cordis et Havgidnis, appeared in 1628. At the commencement of this century the most distinguished Italian surgeon was Hieronymus Fabricius d'Aquapendente (1537-1619), who was a pupil of Fallopius and succeeded him as professor of anatomy at Padua. He was the discoverer of the valves of the veins anil the teacher of Harvey. His principal discoveries and writings relate to anatomy THE HISTORY ASD LITEEATURE OF SURGERY. 57 and embryology, Init lio was also professor of surgery, and his Pcniatcu- chos Chinitr/icnm (f'rancof., 1582) and his Opera Chirurgka (Paris, 1613, in folio, and later editions) were important works of reference during tiie next century. Fabrieius was learned and elocpient, and made the University of Padua the nKjst important school for anatomy and sur- gery in Europe. His surgery is mainly tiiat of Celsus, Paul of JEgina, and Albucasis, to whom he gives full credit, carefully noting the sources of his ([notations. No great advance in the art is due to him, but his works contain manv accounts of cases and references to tiie metliods of other surgeons, making them valuable historically, and they are far more interesting as a piece of literature tiian is the corresponding work of John de Vigo. In speaking of wounds of the intestines he refers to animal sutures and to the insertion of a piece of the trachea of an animal to preserve the lumen of the gut. He describes tracheotomy and urges its performance in certain eases, and says tliat lie has seen one case of cancer of the breast cured by excision, but has never performed the operation himself. Next to him came Cesare Magati (1579-1647), who became professor at Ferrara in 1612 (or 1621?), and who gained much repute by his book, De rara mcdieatlone rulnenim, fieu de vulnerihua raro fracfcaul ix (\\hr\ ii., Venet., 1616, folio). In this he urged a simpler mode of treating wounds tlian was then fasliionahlc, advising less fre()3) being nierely a manual. There is an English translation of this (London, 1717). Hendrik van Roonhuyscn (1625-6?), a surgeon of Amsterdam, also well known as an obstetrician, published his Genees-en Heelkonstuje aanmerfcingen in 1672. He operated for wry-neck and hare-lip, advised Caesarean section, removed tumors, and seems to have been specially skilled in his art. Cornelis Solingen (1641-87), a surgeon at the Hague, wrote 3Ianuale Operatien der Chirurgie (Amst., 1684), which Haller says is full of original observations. Peter A. Verduyn (162?-?), a surgeon of Amsterdam, is celebrated for his treatise on the flap method of amputation. Diss, de nora artuidii decitrtandonuii ratiorie {Am^t., 16i»6). He seems to have known nothing of the similar methods of Lowdliam. (Sec p. ()7.) Joannes Muys of Arnhcm and Leyden jniblished the first two parts of his Pra.vis Chirurgiae rationalis in 1683, and the complete work in 1695. This contains accounts of one hundred and twenty cases, some of which are curious and interesting. Fabricius Hildanus (1560-1624) is sometimes called the "Father of German Surgery," althougli this title belongs more properly to Hcister. He was a Swiss by birth, and for the last twenty years of his life was the city physician of Berne. He was a surgeon's apprentice who man- aged to acquire a good classical education, and probably obtained good practical training under Griffon, a surgeon of Geneva. He travelled much, resided for some time at Cologne, and became widely known as a bold and skilful i)]W'rator, and especially as a lithotomist. He was a strong opponent of Paracelsus and his friend Wurtz, and was a volu- minous writer, but his monographs are, for the most part, of little interest, the best being his Lithotomia Vesicae (Basle, 1626), translated into English and published at London in 1640. His most important ])ublieation for readers of the present day is his Obserrationnin et Curn- tioiiiiiii Vhirurgienrum Venfuriac, in wiiich he relates his experience in a large number of siu'gical cases of the most varied character. He advised amputation at an early stage in gangrene, and that the incision should be made in the sound and not in the decayed flesh. He used the cautery, and not the ligature, in wounds of the arteries, and devised a number of complicated instruments, none of which are of practical interest. His chief influence on surgery was through his correspondence with German physicians and surgeons, and through his urging u])on the German surgeons the necessity for the study of anat- omy. His Opera omnia, of which several editions were published, appears to have been a favorite book of reference for surgeons for many years. John Schultes, better known as "Scultetus" (1595-1645), a pupil of 60 THE IITSTOnr AM) UTEUATVriE OF SURGERY. Fal)riciiis (rA(|ii:ii)i'ii(lc'iit(', hccaiiu' city physician at Uini. His tjrcat M'oriv, the AniKiiiKnitdriiun L'hirurgkmvi (Uhii, l()"j.'3, folio), passed thi'oiigh many editions and was translated into many languages. Joseph Schmidt (KiOl-?), an army surgeon, published Spenilmn ( 'lilruri/lcinii (IJlin, KJTjfJ, quarto) and Kxatiwii C/iiriirf/icujii (Franeof., The most celebrated (icrnum surgeon of tiie hitter part of this j)eriod was Mattha'us Gottfried Purmann (l(j4'j-1711 ?), who was apprenticed as a barber surgeon, became a medical oificer in the Brandenlnirg armv in 1675, and city physician at Breslau in 1685. He was a voluminous writer, and his (r/'o.s.scr vnd f/cuitz neu-f/ewuinJciier Lorbcer-Krantz, oder Wi'i nd-Artsuci/ [Franc(){., 1692, 4to; also 1722), his Chirurgiii Curiosa (Franeof., 1694, 4to; translated into English, Ivondon, 1706, fob), and his Funftziy nondcr- uiid iruiidcrbahre /Schustswunden Curen (Franeof., 1721) are valuable works in the history of the art. He was a strong advocate of the cure by the M'ea]ion-salve and the sympathetic powder, and tells several stories of the successful use of these remedies. He used styptics and bandages to control hemorrhages after amputations, objecting to the eauterv, l)ut savs nothintr about the ligature. Here may also be mentioned John von Muralt (1 645-1 7;33), a dis- tinguished Swiss anatomist and surgeon, who was one of a celebrated family of physicians of Zurich. He studied at Basle, Leyden, Oxford, and Paris, and in 1761 returned to Zurich, where he soon became dis- tinguished as an anatomist and surgeon. In 1677 he announced jjublic lessons in anatomy, M'ith demonstrations on the bodies of criminals and of persons dying of remarkable diseases in the hospitals, and in the same year published his Vade Mecmn Anatomicmn, giving the date by the enlarged letters in the motto of the book, " LVX et faX IMcDICi"- nse." In the second edition of his surgical writings, published in 1711, he describes a method of amputation by fla]> devised by Saborian in Geneva, who first performed it in 1701, and this is by some claimed to be the first mention of that method of operation, but it had already been described by Yonge in 1679. (See p. 67.) Other German surgeons of this period were Mathias Ludwig Glandorp (1595-1636), whose iSpecidum Vhlrun/icitm appeared in 1619 ; Jessenius a Jessen (1566-1621), author of Tnxfitutioncx Vhinirgicac (1601); Paul Ammann (1634-91), author of Pntxix vuincrum lethaliiim (Franeof., 1690); Joh. Agricola (1589-164?), author of Chirurgia parva (Nurn- bei-g, 1643); and John H. Jungken (1648-1726), author of Compendium Chinur/icac Mantndix ahuofutum (Franeof., 1692). The oldest English medical book -which we have is perhaps the Leech- book, written about 970 A. d., and printed in 1865 as volume ii. of the Lecehdoins, Worfeiinning, ((»d l-itarcraff of Early England. This is maiidy the receipt-book of a herbalist, giving the uses of common herbs, and among other things the composition of various " wound-salves." But it also contains matters taken from Paul of ^Fgina, and directs : " If thou must carve off or cut off an unhealthy limb off from a healthy body, tlien carve thou not it on the limit of the healthy body, Init much more cut or carve in the hole and (juick body." The following is the best surgery in the book : " For hare-lip, pountl mastic very small, add the white of an egg, and mingle as thou dost vermillion ; cut with a knife the false THE HISTORY AND LITERATURE OF SURGERY. 61 edges of the lip, sew fast witli silk, then smear without and within with the salve, ere the silk rot. If it draw together, arrange it with the hand ; anoint again soon." In the hook of The Pht/siciaiifs of Myddrni, which dates from about tlie thirteenth century, there are a few references to surgical opera- tions. Tile autlior says (page 40) : "A wounded lung is the physician's third tlitiiculty, for he cannot control it ; but he must wait for the will of God. By means of herbs a medicine may be prepared for any one who lias a pulmonary abscess [empyema]. He should let out [the matter] and support [the patient] as in the case of a wounded lung, till lie is recovered. But most usually he will have died within eleven years [or one year]." Page 44 : " A hard vesical calculus is thus extracted by operation : Take a .staff and place it in the bend of the knee ; then fix both arras within the knees, doubling them over the staff, and securing both wrists with a fillet over the nape of the neck, the patient (being placed on the back), his stomacii \\\^, witli some supjiort under both thighs, and the calculus cut for on tlie left side of the urethra. Let him subsequently be jnit in a water-bath that same day, also the day follow- ing early, and after this he should be put in the kyfteitii. Then he should be removed to his bed, and laid tiiere on his back, his wound being cleaned and dressed with flax and salt butter. He should be kept in the same temperature until it be known wliethcr he shall escape [effects of the operation]. He should be kept without food or drink for a day and a night previous to the operation, and should iiave a bath." The following is the direction for an antesthetic (page 423) : " Take the juice of orpine, eringo, poppy, mandrake, ground-ivy, hemlock, and lettuce, of each equal parts. Let clean earth be mi.xed with them and a potion prepared, tlieii without doubt the patient will sleep. When you are prepared to t)perate upon the jjatient, direct tliat he shall avoid sleep as long as he can, and then let some of the potion be poured into his nostrils, and he will sleep without fail. " When you wish to awake him, let a sponge be pounded in vinegar and put in his nostrils. " If you wish tliat he should not wake for four days, get a penny- weight of the wax from a dog's ear, and the same quantity of pitch ; administer it to the patient and lie will sleep. " Wiien you would that he should awake, take an onion, compounded with vinegar, and pour some into his mouth, and he will awake. Take care that you keep him quiet, and warned of the operation, lest he should be disturljed." The first surgeon in England of whom we have any definite account, and wliose writings still exist, was John of Arderne (or Arden), born about l."]08, who practised in Newark until about 1370, when he went to London. He wrote a treatise on surgery of which several manu- script copies are in existence, but the- only work of his which has been printed is ^1 trcuthc of the fixfuld in the fumhimenf, or other placet of the bodt/, etc., which is included witli the translation of Arcffius on wounds of the head, etc., printed in London in lo8S, liciiig a translation by John Read. His operation itself consisted either of slitting up the fistula or of passing a thread tlirough it, ^\•llich is to be drawn so as to cut through the flesh graduallv. 62 THE HISTORY AND LITERATURE OF SURGERY. His dcscriptiiiii of caiu'cr of tlic rcctiini is a graphic one, and begins as follows : " Bubo is an Apostunie breding within the fundament in the longa- tion with great hardness, but with little paine. This before his ulcera- tion is nothing but a hid Cancer, which cannot in the beginning be knowne by sight of the eye, for it is hid within the fundament, and therefore it is called Bulio. For as an Owle hidctii her self in the dai'ke places, so this griefe lurketh within in the beginning. " Bnt after processe of time it is ulcerat and frettith and goeth out, and oftentimes it frettith and ulcerith all the circumference of the funda- ment, so that the excrements goeth out contimiallie without retencion, and may never be staied unto the death, nor cured by the healpe of man. And it is thus knowen. " Put your finger within the fundament of the pacient, and if ye finde within a thinge very harde, sometime on the one side, and sometime on both, which hindreth egestion, than it is Bubo. " And the manifest signs are these. The patient cannot abstaine from stoole, for aking and priking, and that twise or thrise within an lionre, and the excrementes seeme as it were mingled with watrie blond, and it stinkcth very strongly, so that all the nnskilfull surgions and the patient also thinketh they have Dissenterium, when truel}' it is nothing so, for Dissenterium is with flux of the belly, but in Bubo there goeth foorth hard egestion and sometime they may not goe out for straightnesse of the Bubo, but are reteyned within the fundament straiglitly so that ye may feele them with your finger and drawe them out, and in this case glisters availeth much. "And when they bee nigh their ende, they beginne to have lynger- ing fevers, and to loose their appetite, tlie_y forsake all, and covet wine, they eate little and covet everieday lesse and lesse, they sleepe bnt little and unquietly, they are heavie as well in niinde as in body, and as they waxe weaker and weaker, they covet their bedde and above all thinges to drinke water, neverthelesse they can speake and move themselves to the last breath. " From these (I say) wash your handes if you have care of j'our credit, unlesse it be in glisters as aforesaide to ease him." At the beginning of the fifteenth century there was a great dearth of surgeons in England, as it appears from Rymer's Fcedera that in 1417 Henry authorized " John Morstede to press as many surgeons as he thought necessary for the French expedition, together with persons to make their instruments.' With the army which won the day at Agin- court there had landed only one surgeon, the same John Morstede, who indeed did engage to find fifteen more for the army, three of whom were to act as archers." Of the English surgeons of the fifteenth and sixteenth centuries, those whose names are best known are Vicary, Gale, Clowes, and Lowe. Thomas Vicary (149?-1561), the first master of the Amalgamated Bar- bers and Surgeons in 1541, and one of the first governors of St. Bar- tholomew's, published in 1548 a work on anatomy in English. No copy of this edition is known to exist, but the edition of 1577 was reprinted by the Early English Text Society in 1888. Thomas Gale (1607-86), a ' The Antiquary's Portfolio, by J. S. Forsyth, vol. i., London, 1835, p. 80. THE HISTORY AND LITERATVRE OF SURGERY. 63 native of London, served in the army of Henry VIII. in France in 1 544, and nnder Piiilip II. of Sjmin in 1577, succeeded Vicary as master of the Barber Surgeons Company in 1561, and in 1563 published \\is, Lwti- tui'ion of Chirurfferie, with other treatises, one of whicii is Of icounds made with Gonuetihof, in whicii lie opposes the views of Brunswiclv, De Vigo, and Fcrrius as to the venomous nature of such wounds, and quotes Maggius approvingly. He advises styptics in amputations — says that his method is used in St. Thomas's Hospital, and gives cases to prove that bullets may be left in the body without danger. William Clowes (1540-1624) was at first a naval surgeon, and became surgeon of St. Bartholomew's in 1581. He wrote A proved practise for all young C'hirurcjions concerning buniingn with Gnnpowder and Woundes made with Gunshot, etc. (London, 1 SOI ,'.S° ; 3d ed. 1637,4°). He refers to Pare as a man worthy of admiration, and, like Gale, comments severely on the ignorance of the so-called surgeons of his time. Peter Lowe (155?-161?), a Scotch surgeon, practised for a long time in France and Flanders and as an army surgeon. In 159(5 he \\as in London, where he published his works on the Spanish Sickness and The Mliole Course of Vhirurgerie. In 1598 he returned to Glasgow, and founded the Fac- ultv of Phvsicians and Surgeons of Glasgow, which was chartered by King James VI. in 1599. His book on surgery passed through four editions, and is a good manual for its time. In amputation for gangrene he used the actual cautery, but says : " In amputation without putrefac- tion I finde the ligature reasonal)le sure ]irii\i(ling it be quickly done." This is perhaps the first mention in Kuglisli of the ligation of arteries in amputation. In hernia he advised the pricking of the intestines with a needle to discharge the wind and lessen the bulk of the tumor. About the middle of the sixteenth century there lived at JMaidstone, Kent, a surgeon named John Halle, who published in 1565 a translation of the ( 'hirurr/ia parva of Lanfranc, with some remarksof his own, entitled An Historical Expostulation cdso against the beastly abusers, both of Vhy~ rurgerie and Physiche in our tymc : With a goodly doctrine, and instruc- tions necessary to be marked and followed of all true Chirurgies. The history of surgical corporations in England begins with the bar- bers' guild, which was at first a meeting for social and religious purposes, originating probalily in the thirteenth century. These barbers soon began to call themselves barber surgeons. There were, however, sur- geons who were not barbers, some of whom had served in the army, and in 1368 these surgeons formed a separate guild, which about 1421 com- bined with the physicians.' The barbers obtained a eliarter of incorpora- tion from King Edward IV. in 1462. There is notiilng in the charter about bnrl)cry — that is, shaving and hair-cutting — Iiut a good deal about the regulation of surgery. In 1492 arms were granted to the " Guild of Surgeons," whicii appears to have been a small body of eight or ten men superior in social position to the ' The details of the quarrels between the barbers and the surgeons, and of the organ- ization and ])rogress of the guilds, will lie found in The Annals of the Barber Siirgeonx of London, compiled by l^idney Young (a thick quarto volume published in 1S90), and in The Ch-aft of Siirf/ery, by J, Flint South (published in 1886). The act of Parliament passed in 1540, allowing the United Companies of Barbers and Surgeons to have yearly four bodies of criminals, was the first law in the country for promoting the study of anatomv. 64 THE HISTORY AM) MTEUATURE OF SVIWKRY. l)arber.s. In 1540, uikUt the rcitrn of Hciirv VIII., tlie barbers and the surgeons were united and incorjiorated In- act of Parliament as the Company of tiie Barber Surgeons, tiie first inastei' Ijeing Thomas Vieary. lu the year 1542 an act was j)assed regulating the j)raetiee of surgery, stating that "the Company and Fellowship of Surgeons of London, minding their owne lucres, and nothing the profit or ease of the diseased or patient, have sued, troubled, and vexed divers honest persons, as well men as women, whom God hath endueed with the knowledge of the nature, kind and operation of certain herbs, roots and waters, and the using and ministering of them, to such as have been ]iained «ith custum- able diseases, as women's breasts being sore, a pin and the web in the eye, uncomes of the hands, scaldings, burnings, sore mouths, the stone, stran- guary, saucelin, and morphew, and such other like diseases And yet the said persons have not taken anything for their jiains or cunning. .... In consideration whereof, and for the ease, comfort, succour, help, relief, and health of the King's poor subjects, inhabitants of this his realm, now pained or diseased. Be it ordained, etc. that at all time from henceforth it shall be lawful to every person being the King's subject, having knowledge and experience of the nature of herbs, roots and waters, etc., to use and minister according to their cunning, experience and knowledge, .... the tiforesaid statute .... or any other Act notwithstanding." The Barber Surgeons had public demonstrations of anatomy and dis- sections in their hall, but it was forbidden that any of them should make dissections or give lectures on anatomy at any place fithcr than said hall. The reader in anatomy was for many years a ])hysician. In l(i()4 the comjwmy was presented with five hundred copies of the Tables (if Surf/er}! of Horatius Morns, a Florentine physician, translated by Kichard Caldwell' (London, 1585, .32 pp. 8°). These books were given by j\Ir. Caldwell to be distributed among the surgeons who were freemen of the company. In 1643, Edward Arris gave to the corporation the sum of two hun- dred and fifty pounds for the pur^iose of having one human body pub- licly dissected and six lectures thereupon read each year. The Gale Lectureship was tbunded by Dr. Gale, the order being issued in l(i98. These two bequests are now combined and the lectures in con- nection with them are known as the Arris and Gale Lectures. One of the lecturers before the Barber Surgeons was Alexander Read (or Rhead), a Scotchman, who graduated in 1620 at Oxford. His Lec- turei< on wounds were published in 1(534, those on tSiirc/ical operations in 1637, and all his works in 1650. Read taught that a bullet may be so made that it will make a poisonous wound, quoting as authority Querce- tanus. Speaking of ligature of the artery, he says : " Ambrose Parrey ■would have this mean to be used after the amputation of a member, whom you may read ; but in my judgment his practice is but a troublesome and dangerous toy ; as he shall finde who shall go to make trial of it." An important part of the business of the Corporation of Surgeons was ' The Dr. Caldwell referred to was Richard Caldwell, a graduate of O.xford and a physician, and president of the college in loT(l. Through his intlnence Lord Luniley founded and endowed a lectureship on surgery, which is still known as the Lumleian Bequest. THE HISTORY AXD LITERATURE OF SURGERY. 65 the examining and licensing of naval snrgcons, both for the royal navy and for merchant ships. An account of such an examination is given by Smollett in his novel Boderick Bandom. Oliver Goldsmith also pre- sented himself for examination in 1758, and the minutes of the court of examiners read as follows : " James Bernard, mate to an hospital ; Oliver Goldsmith, found not qualified for dito." In Scotland the University of Aberdeen was founded in 1494, and in 1505 had a professor of medicine. King James III. is reported to have been "ane singular gude chirurgian, and there was none of that profession if he had any danger- ous cure in hand but would have craved his adwyse." His method of obtaining practice must have been effectual, although it was an unusual one. \ie find in the accounts of the treasurer for 1511 an entry as fol- lows : " Item to one fallow, because tiie King pullit forth his tootht, xiiii. 5." The first charter of the Royal College of Surgeons of Edinburgh is dated July 1, 1505. It directs that no person shall make use of the craft of surgerv or of barber craft within this burgh unless he is freeman and burgess of the same, and that he must be examined by the masters of the same craft upon the following points — namely : The anatomy, nature, and complexion of every member in man's body, and all the veins of the same. Every year one executed criminal was to be given to the college for anatomical purposes. No master of the craft shall take any apprentice who cannot write and read. Probably the most important provision was, that no person -within the burgli shall make or sell any aqua vite except the masters, mcml)ers, and freemen of the corporation. By 1589 it had become the custom to admit barbers at a lower rate, but tiiey had only the right to act as barbers, being specially forbidden to practise surgery, and were to have " na signe of chirurgie in their bughts or houses oppcnlie or privatlie." In the early part of the seventeenth century the leading British sur- geons were Clowes and Lowe, already referred to, and John ^^\)odall (156?-164?), who had served as an army surgeon, and about 1612 was elected surgeon to St. Bartholomew's Hospital and likewise surgeon-gen- eral to the East India Com])any, which last gave him the ap])ointing of surgeons and mates to all the company's ships. In 1G17 he published a work entitled T/ir Suir/eoiifi Mate or Milifari/ i{- Doincstiquc Surgery. Discoursing faithfully & plainly the method and order of the Surgeons chest, the uses of the instruments, the vertues and Operations of the Medicines, and the exact Cures of Wounds made by Gun-shott, etc. In 1628 he published a work entitled Viatknim, Being fhe Bafh-Wcnj to The Surgeotitt Chefit. Containing, Chirurgical Instructions for the yongcr sort of Surgeons, imployed in the Service of his Majestic, or for the Common-Wealth upon anjt occasion whatsoever. Intended chiefly for the better curing of Wounds made by Gunshot.' His ' These works were afterward pnblisheil together in folio in l()o9, 1G53, and 1658, a separate tille-p.age being given to each work, but the pagination being oontinnons. The second title-page is often transferred in place of the lirst one, which has been lost, lead- ing, on careless examination, to the erroneous supposition that tliey are two entirely dis- tinct works of the same date. Vol. I.— a 66 THE HISTORY AND LITERATURE OF SURGERY. works arc not specially instructive, hut are in parts very good reading. In ani|)utatiou he recommends tying large vessels, especially those of the thigli, if it can be done, but he seems to think that the surgeon will often fail, in which case, as well as for the smaller vessels, he recommends buttons of astringent and caustic powders. In gangrene Woodall urged amputation in the mortified instead of the sound part — an old treatment which had then fallen into disuse. He also' suggests amputating as low as the ankle for disease of the foot, instead of just below the knee, as was usually the case. He had never seen the actual cautery used in amjnitation. In 1648, James Cook of Warwick published his MrUififliim Cliirur- giae, or the Harrow of Surgery, a manual which seems to have been j)opular, the sixth edition in 1717 being "licensed by the College of Physicians and fitted for the use of all sea-surgeons." In his descrip- tion of amputation no mention is made of the ligature of arteries. The greatest English surgeon of the seventeenth century was Eichard Wiseman (1622-76), sometimes called the English Pare. He was apprenticed to a barber surgeon in 1637, served in the Dutch navy until about 1644, when he joined the army under Charles I., and was admitted to the Company of Barber Surgeons in 1651. He was a surgeon in the Spanish navy for three or four years, and in 166(1 joined King Charles II. and was appointed one of his surgeons. In 1672 he ])ublished A Treatise of VVoundx in an octavo of 277 pages. In 1676 this was enlarged and printed in a large folio volume under the title Severall Chirurgieall Treatm's. There were eight of these treatises — viz. I. Of tumors ; II. Of ulcers ; III. Of the diseases of the anus ; IV. Of the King's evil ; V. Of wounds ; VI. Of gunshot wounds ; VII. Of frac- tures and luxations; VIII. Of lues venerea. In 1686 this was pub- lished in folio, having the words " the second edition " on the title-page, although it was really the third, and the so-called " third edition " (folio, 1796), \vith the title Eight Chirurgieal Treatises, etc., was really the fourth. Other editions appeared in 1705, 1719, and 1734, and there is a spurious edition of 1692, which is really the original edition of 1676 Avith a new title-])age. ^V^iseman used the complex dressings of the period, but knew that simple measures produced equally good results. He used styptics and cauteries, and not the ligature, but he included the end of the cut vessel in one of the stitches through the lips of the Avonnd. Being a personal friend of the king, he used his influence with him to promote the inter- ests of the Barber Surgeon's Company. His Avorks Avere ncAcr trans- lated, and Ayere A'cry little known on the Continent, lint they had a decided influence on the improA'ement of the art in Englantl. James Yonge (or Young) (1646-1721), a natiA'e of Plymouth and a naval surgeon, published in 1679 a little book of 120 pages entitled Currus Triumphalis, e Terebintho. Or an account of the many admirable Vertues of Oleum Terebinthinae. 3Iore 'particularly, of the good effects produced by its application to recent Wounds." .... And lastly, A new Way of Amputation, etc. He objected to Pare's method of liga- tures in amputations, saying that it is " a Avay ahyays tedious, often successless ; and AvhateA'er A'aunts the Author makes of it, it cannot be so secure as he pretends ; it being liable (sometimes from the slackness, THE HISTORY AND LITERATVUE OF SURGERY. 67 otherwise from the too great straightness of the thred ; sometimes from its sinalhiess, cutting- through, or from its weakness, giving way) to a new flux when not so tolerable to the Patient, or so easily cured by the Artist as at first; moreover,, where two Vessels or more bleed in one Wound (whit'h is very frequent), the one must be neglected, while the Ligature is making on the other." But he says : " The ligation of an Artery on other accounts, as in the Toothach, Epiphora, Aneurisma, &c., is not hereby impugned." On page 30 is to be found, perhaps, the first printed description of a tourniquet — "very useful in iVmputations, espe- cially above the knee ; that is to say a wadd of hard linnen cloth, or the like, inside the Thigh a little below the Inr/iicn, then ])assing a Towel round the member ; knit the ends of it together, and with a Eattoon, a Bedstalf, or the like ; twist it, till it compress the Wadd or Boulster so very strait in the crural vessels that (the circulation being stopped in them) their bleeding when divided by the Excision, shall be scarce large enough to let him see where to apply his Restrictives." A similar tour- niquet had, however, been used l)y John Morell in 1674 at the siege of Besaiifon. The " new way of amputation " is by a single flap, and is the first printed description of this method, which he says he learned from Mr. C. D. Lowdhara of Exeter. The Complmt Discourse of Wounds, . ... as also a Treatise on Gunshot Wounds in General, by John Brown (surgeon to the king) (London, 1678, 4to), is a pompous, diffuse, tedious book, containing nothing of any impcu'tance. Some curious illustrations of the English surgery of the middle of the seventeenth century are to be found in the Diary of the Rev. John Ward, Hear of Strntford-upon-Avon, extending from 16^8 to 1679, edited by Charles Severn (London, 1839, 8vo). For example: "A cancer in ]\Irs. Townsend's breast, of Alverston, taken off by two sur- geons First they cutt the skin cross and laid itt Iwick, then they workt their hands in ytt, one above and the other below, and so till their hands mett, and so brought itt out There came out a gush of a great quantitie of waterish substance, as much as would fill a flag- gon.

" Gill told mee of a woman that had an apostheme about the side, and his master intended to trc])an her on one of the ribs ; whether it canne be ; — I suspected itt to Ix' a ly." " The mountebank that cutt wry necks, cutt three tendons in one child's neck, and hee did itt thus ; first by making a small orifice with his launcet, and lifting upp the tendon, for fear of the jugular veins, then by putting in his incision knife, and cutting them U])wards ; they give a great snaj)p when cutt. The orifice of his wounds are small, and scarce any blood fiillows." " Gill said Jiis Mr. Day hath amputated five armes, three leggs and somewhat else since he came to Oxford, and but two of all these died, and one was a person of sixty years att least."

A curious episode in the history of surgery in the iirst ludf of the seventeenth century is the controversy on the sympathetic or magnetic cure of wounds. This was a doctrine of Paraeeksus, and in 1(508 one of his foUovyers, (ioclenius, professor of medicine at ^larhurg, called special attention to it by iiis \york, Trdddtun ur/iae, .... libri sex, and in 1582 his De vidneribus capitis. Juan Fragosa, surgeon to Philip II., published Erotemas quirurgicos (Madrid, 1570, 4to), De la Cirur/ia, etc. (Madrid, 1581, fob), Tratado de cirtKjia saeado de la cirugia unieersid, a little manual of questions and answers for students (1692), and Cirujia universal, ....

Cristobal ]\Iontcmayor, surgeon of Kings Phili]) II. and III., wrote Medici nia y cirur/ia de rulnerihus co^;///.s' (Valladolid, 1613; Saragossa, 1664). Pedro Griigo de Vadillo, a .surgeon of Lima, published at Madrid, in 1632, Discursos de verdadera cirugia y censura de ambar vias, y eleccion de 1(1 primera intcncion curatira, y unicion de las heridas, of which a third edition appeared in 1692. Eighteenth Century. At the beginning of the eighteenth century the only city in which there were any special o])portunities for the study of surgery was Paris. There was no place for the barbers or the barber surgeons in the univer- sities of P^urope, and they had no institutions of their own in which any teaching worthy of the name could be obtained. Many of them had learned something in the camp or on the battle-field, which was the great practice school for the surgeons, as it had been for three centuries, 70 THE HISTORY AND LITEUATURE OF SURGERY. and there were hut few surgeons of the time in Enghind, I*' ranee, or Germany wlio failed to gain experience therein. Nevertheless, this military experience contributed little to the advancement of surgery. Haeser says that tlie cliief cause of tiie supremacy of French surgery in the seventeenth and eighteenth centuries was the wars undertaken by Louis XIV. and his successors, and that streams of German blood con- tributed in some degree to the foundation of the mastt-i'ship of the French in tlie i)is /cs niftinx Irx (llfforiiiiih du corps (Paris, ] 741), being tlie first work in wiiicli tiic word (irtlidpu'ilia is used. It is a ])i)j)- idar treatise on the eare of children, and has very little to do with oi-tlio- piedia as that word is now understood. The most distinguished surgeon of the first half of the eighteenth century was Jean Louis Petit (1674-1750), who entered the army at the age of eighteen. In 1700 he settled at Paris and commeneed giving a private eourse of lectures in anatomy and surgery. He invented tiie screw toui'niquet, an appliance of ahnost as nuicii importance as tlie liga- ture to tlie surgeon who iias to ani[)utate with unskilled assistance, devised herniotomy without opening the sac, and made an improvement in tiie circular method of amputation l)y cutting successively the skin and tiie muscles, instead of dividing them at (jne stroke according to the old method. This was carried still further by Desault, who divided the muscles on two levels. To Petit also is due the credit of having first demonstrated the mechanism of the occlusion of arteries in wounds, showing the chief process to be the formation of a clot, a part of which surrounds the end of the vessel and a jiart of which is a plug oceujjying the cavity ; and of giving the first account of moUities ossium. After the triumph of the medical faculty over the surgeons and l)ar- ber surgeons in tiie middle of the seventeenth century, the College of St. Come continued to give instruction, although it could not grant degrees, and in 1690 the number of the students was greater than the number of students in medicine, being over seven hundred. It was by no means poor, and in 1691 it began the construction of a new amphitheatre, which was completed in 1694.' In it were given lessons on anatomy and sur- gical operations, and similar teaching was given by a few ambitious young surgeons as a private enterprise. To lieconie a member of St. Come the aspirant must have been an apprentice for at least six years before he could present himself to perform his " grand chef d'ceuvre," which, if successful, would make him a master surgeon. This "grand chef d'teuvre" was a long process of examination. The Washington I^ibrary contains a manual of preparation for it, in the form of a neatly-written manuscript, bound in four volumes, 8vo, " par C. Caulay, recu chirurgien jure le 24 judlet, 1737." Fran9ois de Lapeyronie (1678-1747) was a surgeon of Montpellier and demonstrator of anatomy in the School of Medicine. He came to Paris in 1714, soon became surgeon of the Charite, and first surgeon of the king in 1736. He was wealthy, and spent his money freely for the benefit of the Royal Academy of Surgery, which was organized in 1731, increasing in fame and jjrosperity for the next forty years, and through the agency of which, to a considerable extent, Paris became the great surgical centi-e of the world. J. L. Petit became the first director of theacademy, and Sauveur-Francois Morand (1697-1773) its first secre- tary. Morand was an ingenious surgeon. He proposed amputation at the hi])-joint and ovariotomy, and performed the high o])eration for stone, but he was an uneducated man, and Mas unable satisfactorily to perform the duties of secretary of the academy, which post he resigned in 1739. He was succeeded' by Autoine Louis (1723-92), to Avhom the success of the academy and its marked influence on the progress of ' Corlieii : La France Med., 1878, xxv. p. 481. THE HISTORY AND LITERATURE OF SURGERY. 73 surgery are to a great extent due. He was professor of physiology, and in 1757 became surgeon of tlie Ciiarite, l>ut he was not so much an •operator or inventor as he was a learned historian, editor, and critie. An indispensable work for the student of the history of surgery in France at this period is the collection of eulogies pronounced by Louis upon deceased members of the academy, published with notes and appendices by E. F. Dubois in 1859. These so-called Mo(/cs are judi- cial, critical, historical essays whicli are unt'cpiallcd in surgical luograjiiiy. .A.t the conuneucement of liis eulogy on Le Cat lie remarks that tiiese memoirs will form a part of the liistory of the ^^cademy to be read in years to come, and tliat the truth must be told ; and in this he was a true prophet. His (EVcre.s diccrM's de chlrurgic were published in 1788. Of the earlier members of the academy, besides those already named, the most distinguisiied were Le Dran and Le Cat. Henry Fran9ois le Dran (1685-1773), the son of a surgeon, was educated in Paris, and became a master in surgery at the age of twenty-two. In 1724 he was appointed one of the four surgeons of the Charite, and established an anatomical school there, and in 1730 published his Parallele des diffe- rentf'K mnni^re de tirer la pierre hors de la vessie, which gaye him much reputation. In 1734 he was sent as chief surgeon to the army, and pub- lished the result of his obseryatious in 1737 in his Traitc .... ■mr Ics j)l(ii/cn d'armcft a feu, which went througii several editions. In 1742 he j)ublishcd a treatise on operative surgery. Le Dran made no great con- tribution to surgery, but he was a celebrated teacher and had many ])upils from Germany, through whom his method became popular in that country. Claude Nicolas le Cat (1700-68) was a surgeon of Rouen, wiio l)ei'ame surgeon-in-chief of tlie Hotel Dieu of that city as the result of concoiu's in 1729. He won many prizes from the Academy of Sur- gery in Paris, being specially skilled in " prize-essay writing," became professor of anatomy and surgery in the school established at Rouen in 1736, and attracted many students. He was a voluminous ^vriter, l)ut his papers wiiich relate to litiiotomy are tiie only ones of any special A'alue. His rejnitation was greater abroad than it \vas at home. Otlier surgical writers of this period are (Tuillanmc Mauquest de la Motte (1655-1737), whose Trade complet de chirurr/ie (3 vols., Paris, 1 722) was a very popular text-book ; Georges de la Faye (1699-1781), whose Priiicipes de rhirure/ie (Paris, 1739), an elementary handbook, passed through many editions and translations; and Elie Col de Villars (1675- 1747), whose ('ours de ehirun/ie a])peared in 173.S. Dominicjue Anel (1678-1725 ?), a native of Toulouse, was a pupil of J. L. Petit, a surgeon in the French and Austrian armies, and a wan- derer over Europe. In 1710 he ligated the brachial artery of a priest in Rome for traumatic aneurism, and tliis is claimed as a triumph of Frencli surgery preceding the metiiod of John Hunter. In fict, it was tiie operation performed and dcscril)ed long bef )re by Guillemeau. In Genoa, in 1712, he devised his operation for lachrymal fistula and the syringe \vhich still bears his name. In 1716 he was practising as an eye surgeon in Paris. George Arnaud de Ronsil, a French surgeon, went to London prior to 1748, and remained there until his deatii in 1774. His Dissertation 74 THE HISTORY AND LITEUATUBE OF SURGERY. on Hernia (London, 1748) was a ])a))t'r of niiioli importance. His Memoires de chirurf/le (London, 1702, 2 vols. 4to) cdntains matter of permanent value, and a curious paper, " Inconveniens des Descentes par- ticuliers aux Pretres de l'£glise Komaine," with reference to Leviticus xxi. 20. In 1732 he excised the caecum and a part of the colon and ileum in a case of hernia. Jean Baseilhac (1703-81), better known as Frere Come, was the son of a surt;eon and was educated as such. In 1729 he became a monk, but continued to practise surgery among the poor, and invented the lithotome cache. He published anonymously in 1751 an account of his operation, and in 1779 published a paper on the high operation. He was a skilful surgeon, and obtained greater success with his instru- ment than any other person has been able to do. Pierre Brasdor (1721-97) was professor of anatomy and operative surgery in the College of Surgeons of Paris, and contril)uted to the Memoirs of the Academy of Surgery. His name is remembered in con- nection with his suggestion to treat certain aneurisms by ligation of the artery on the distal side of the tumor ; which was first done by Wardrop. Francis G. Ijcvacher published in the Memoirs of the Academy of Surgery, in 17(j9, a paper on gunshot wounds, in which lie, for the tirst time, showed that what were sujiposed to be the effects of the wind of a ball were really due to the ball itself. Hugues Ravaton, a surgeon of the French army, published in 1750 the best treatise on gunshot wounds which had yet appeared. His Chinirgie rVarm^e was issued in 17(j7, and his Pratique moderne de la ehintrgie in 1770. He was the first to practise amputation by the double-flap method. Jean Joseph Sue (1710-92), son of a Paris surgeon, and often men- tioned as "Sue le jeune," was a teacher of anatomy, and in 1761 one of the surgeons of the Charite. He published £lemenh de chirurgie (Paris, 1755), Traite des bandages (Paris, 1761), and Dictionnaire posifif de chirurgie (Paris, 1779). Jean Louis Belloq (1730-1807), a professor of anatomy in Paris, devised a number of instruments, among which was the canula for plugging the posterior nares still known by his name. In the latter part of the century the leading surgeon in Paris was Pierre Joseph Desault (1744-95), who became surgeon of the Hotel Dieu in 1788, and soon had a crowd of students following his public clinic, the like of which had never been seen before. He was a pupil of Louis and of Morand, and surgeon of the Charite in 1782. He ■was the first teacher of surgical anatomy in the modern sense of the term, made many improvements in the treatment of fractures, and con- tributed largely to the perfecting of surgical technique. He wrote almost nothing, but his pupil, Bichat, gave the substance of his teach- ings in the CEuvres chirurgimles (3 vols., 1798-1803). In 1792, Desault was arrested on the charge of having poisoned the wounds of some of the revolutionists who had been brought to the Hotel Dieu. It was then but a step from the prison to the scaffold, and his pupils formed themselves into a deputation to defend him before the tribunal, their spokesman being Jean Pierre Maunoir, a young Swiss, afterward a celebrated sur- geon in Geneva, whose pleadings prevailed and Desault was released. THE HISTORY AND LITERATURE OF SURGERY. 75 The Hotel Dieu of Paris was the " oldest, largest, richest, and worst hospital in Europe." In the latter part of the eighteenth century it con- tained over twelve hundred l>eds, and sometimes over three thousand patients, having four or five in one bed. The first distinct mention of surgeons in the Hotel Dieu occurs in the records of the year 1539, in which it is ordex-ed that the surgeon Jocot la Normand shall be retained to serve as surgeon in the Hotel Dieu in place of George Barbas at a salary of about one hunilred antl eighty francs. By declai'ation of the managers in 1(505 the surgeon nuist call a physician to see all the opera- tions of surgery which he shall make witliin the Hotel Dieu. In 165-1, Jacques Petit, master of surgery in Paris, was named sur- geon of the Hotel Dieu. This was an invasion, for up to that time the surgeons had been chosen from among tlie surgeons of the hospital. This Jacques Petit gave a course of anatomy to the pupils in the hos- pital, commenced the collection of instruments of surgery, and gave a sort of course of surgery at the liedside. Tliis was tiie beginning of clinical surgery in this hospital and in France. He entered the hotel at the age of thirteen, studied sui'gery there, and filled the place of sur- geon-in-chief until 1705. The story was that he was more than sixty years in the house without putting his foot outside of it. He was succeeded in 1 705 by Mery, one of the most celebrated of the surgeons of this period. Mery was succeeded in 1722 by Thibault, he by Pierre Boudou, and he by Moreau, who was succeeded by Desault in 1786. Desault was succeeded by Pelletan in 1795. The records of the Hotel Dieu which escaped the fire of 1871 have been published by the Bureau of Public Assistance under the title Col- lection ill' ilocHincnis pour acvrir <), I'hixfoire des hopitaii.v de Paris (Paris, 18S1-S7). In the second of these volumes, pul)lished in 1883, are given the deliberations of the governors of this hospital for the years 1768 to 1791, at the time when the hospital was badly overcrowded and com- plaints were being made by the surgeons of the management of the institution. Among other things, it contains a copy of the memoir of the Sisters in charge of the hospital, who in 1 789 made a complaint against Desault to the effect that he was bringing pupils from tiie out- side into the amphitheatre, which should be reserved for the pupils of the hospital alone, that the dressing of wounds was being interfered with, and that from two to three hundred strangers were admitted every day to hear iiis lectures. To this there is a long reply by Desault, show- ing that tlie complaints were in part ill founded, and urging that it is contrary to the public good to confine clinical instruction to the pu))ils resident in the house. The matter was investigated and the decision was given in favor of Desault. A very interesting description of the old Hotel Dieu, showing the arrangement and character of the beds and furniture, overcrowding, etc., is given by Dr. J. B. Tenon (1724-1816) in his Mciiwires stir les hopitau.v dc Pari.i (1788, 4to). Francois Chopart (1743-95) became professor in 1771, and in 1780 published, with Desault, the Traite de.s maladies chirurgicales et des operations, etc., which contains some of Desault's views, but which was wholly written by Chopart. His name remains connected with a form of partial amputation of the foot first described in 1792. Raphael Bicnvenu Sabatier (1732-1811) was a pupil of Petit, and 76 THE HISTOllY AM) LITERATURE OF SURGERY. hceanie professor of anatomy in the Royal College of Surgery. His princi])al work was his Dc hi m/'rhrinc ojjeratoire (ti voh., 1 7!).S-1S10). J. Fr. l>('S('hanip.'< ( 1740-1X24), a ])M|)il of Moreau and surgeon of till' diarite, l)rought tiie Hunterian ojteration for aneurism into notiee in France, and published an interesting historical treatise on lithotomy in 1796. Francois Quesnay (l(;fl4-1774), secretary of the Academy of Surgery, wrote a work on the iiistorv of surgery in I'^'auce wliich is full of errors. Antoine Portal (1742-18;52), professor of anatomy in the Royal Col- lege of France, is the author of Hidoire dc P anntomie et de la chirurgie, etc. (7 vols., Paris, 177()-7o), which is a useful book of reference. Jean Rene Sigault studied surgery at Paris, and was received as mas- ter in the school in 1770. In 1768 he presented a memoir to the Royal Academy of Surgery proposing to substitute the section of the symphysis of tiie pubis for the Ctesarian section. The proposal was not aj)j)roved, but he performed the operation in 1777 with success, and, as he had become a doctor of the Faculty of Medicine, his new operation was received with great enthusiasm by the members of the faculty. He ])ublislied his Memoire [xur la section de la sipnphyse des os pubis, pratiqia'c sur la femme Soiu-hot'\, lu aii.r assemblees dii 3 d du 6 decembre, 1777 (16 pp. 4to, Paris, 1777), and Discours sur les avanfar/cs de la section de la symj^lujse (8vo, Paris, 1778). Georg Fischer, in his Chirurgie vor 100 Jahrcn (Leipzig, 1876), has given a graphic picture of the condition of surgery and surgeons in Germany in the eighteenth century. The great mass of the ]>eople ermitted all executioners, Init only the skilful ones, to practise, and if tlie surgeons THE HISTORY AND LITERATURE OF SURGERY. 77 are as skilful as they pretend to be, every one will rather trust them than go to an executioner ; but if the surgeons are ignoramuses, the public must not sutfer, but must submit to be treated by the executioner rather than to remain lame and crippled. In Germany the first surgeon of importance in the eighteenth century was Lorenz Heister (1683-1758), a native of P'rankfort-on-the-Maiu. After studying medicine for four years at Giesseu and other German universities, he went to Amsterdam in 1706 to study anatomy and sur- gery under Ruysch and Ran, and took his degree at Leydcn in 1708. He gained experience in the army hos])itals at Brabant and Flanders, made a tour into Great Britain, and in 1710 became professor of anatomy and surgery in tiie University of Altdorf Here he lectured in Latin, l)ut found the students and young surgeons so ignorant that he determined to print his system of surgery first in German, which he did at Nuremberg in 1718, as he states in his preface to later editions, and as given in bibli- ographies. I have, however, never been able to see a copy of this date, the earliest edition in the Washington Library having the imprint " Niirn- berg, bey .loluuin Hoffmanns seel. Erbeu, im Jahr nidcexix." The work was a very ])i)pular one, and M'as translated into Latin, and thence into English under the title of A general Hystem of surgery (1743; 7th ed. 1759), forming a thick quarto which is still excellent reading for a surgeon. Sharp saj^s, in the preface of his Critical enquiry (1750), " Heister's Surgery is in every body's hands, and the character of Heister is so well established in England, that any account of that work is needless." The other German university professors of surgery in the first half of the eighteenth century who are worthy of note are Haller, Platner, Mauchart, and Bass. xVlbrecht von Haller (1708-77), a native of Bern, a pupil of Boer- haave, and one of the greatest physicians wlio ever lived, was professor of anatomy and surger}' in the University of Gottingen from 17.36 to 1753, and exerted a powerful influence on the development of anatomy, jihysiology, and surgery through his \vritings and his pupils, who came to him from all parts of Europe. He never performed a surgical opera- tion on the living body, and his teaching in stu'gery was therefore purely theoretical. His Bihliofbcca chirurgica (2 vols., Berne, 1774-75) is the most valual)le work on the history and literature of surgery that has ever been published. He placed on a firm foundation the experimental method in dealing with surgical problems wdiich was a little later so successfully employed by .Tohu Hunter, and which has contributed so much to our kno\vle(lge during the present century. Johann Zacharias Platner (l()!t4-1747) was ])rofessor of auatomv and surgery in the University of Leipzig from 1724 until his death. His Iniiiitutiones chirurgice rationales turn medica', etc. (Leipzig, 1745) jiassed through several editions and was trn-islatcd into German and Dutch. Burchard David Mauchart (1696-1 751) studied at Tiibingen, Altdorf, and Paris, and became professor of auatoiuv and surgcrv in the Univer- sity of Tiibingen in 1726. He devoted himself chiefly to the anatomy and diseases of the eye, and left no systematic treatise, but published a nund)er of dissertations, which were collected after his death and pub- lished in three volumes (Tubingen, 1783-86). 78 THE IIISTORY AND LITERATURE OE SUROERY. Hi'inric'li Bass (1670-1754) bccamo professor of surgery in the Uni- versity of Halle in 1718, and in 1720 ])ul)lislK'(l his (irihullirlier Bfrivht von Jiiniere, and was devoted exclusively to the education of medical offic'ers for the army, retaining a special connection with the Charite.' An institution similar to the Pepiniere, and for the same pur- pose, was organized in Dresden in 1748 as the "Collegium Medico- chirurgicum." - The three German military surgeons of chief repute during this period were Schmuckor, Bilguer, and Theden. Johann Lebrecht Schmucker (1712-86) was educated at the Pepiniere, and sent to Paris for two years by the king to study under Le Dran. He became the surgeon-general of the army, and pnljlished the results of his experience in his Chirurgischc Wahntchmungcn (2 parts, 1774) and Vermisohte chirurgische Schriften (3 vols., Berlin, 1776-82). His observations on wounds of the head and trephining and on amputations are the most valuable of his writings. Joh. Ulrich Bilguer (1720-96) studied at Strasburg and Paris, and entered the army in 1741. In 1757 he became the second surgeon- general. In 1761 he published his />(■ mernhrorum ampufatione rarissime administranda, etc., which passed through numerous editions. In this he opposed the excessive tendency to amputation of his time, which was rather encouraged by Schmucker, and went to the other extreme. His Chinirglsche Wahrnehinungrn (Berlin, 1763; translated into English, London, 1764) is his most important work. Joh. Christ. Anton Theden (1714-97) was educated as a barber sur- geon, entered the army in 1737, and became third surgeon-general in 1758 and first surgeon-general in 1786. His Neue Bemerkungen mid Erfahrungen zur Bcrcichcriing der Wundarzneykunst mid 3Icdicin (pub- lished in 1771 and later editions, also in a French translation) contains accounts of some remarkable cases and surgical methods — so remarkable, ' For details consult Das Konigl. preus.

For tlie ligature of arteries in am- putation he substituted graduated compresses and tiie use of a certain wonderful lotion, the " arquebusade," composed of vinegar, alcohol, sugar, and dilute sulphuric acid, with some salt of lead. He strongly advocated methodical bandaging of the extremities, claiming by its use to have cured aneurism, varix, etc' In the last half of the century the two chief German surgeons were Von Siel)old and Richter. Carl Casper von Siebold (1736-1807), the son and apprentice of a surgeon, served for a time in French hospitals, and studied in Paris under Morand and in I^ondon under Pott and Bromfield. In 1769 lie became professor of anatomy, surgery, and obstetrics at AViirzljurg, and soon acquired great reputation as an operator and clinical teacher. He was succeeded as professor and as surgeon of the Julian Hospital by his son. Job. Barth. Siebold (1774-1814), who founded a journal called Chiron, devoted to surgery. August Gottlieb Richter (1742-1812) became professor of surgery in Gottingen in 1766, and gave a new impulse to the study of that art in Germany, l)eing the tirst to jilace it on a scientific basis. He was the best teacher of surgery in Germany in his day, had travelled extensively, was familiar with the good work then going on in France and England, and was an excellent writer. His Ahhandhmg von den Bruehcn (1777-79) was the best book on hernia up to that date, and is still a classic. His history of surgery, Anfaiu/.'^;/ri'in<1e den WundarzncifkiDist (7 vols., 1782-1804), is a model in arrangement and style, but is not complete. His journal, the Chirurgische Bibliothck (15 vols., 1771-96), did more to develop surgery in Germany than any previous agency. In Austria there is little worthy of note in the history of surgery until the latter part of the century. Gerard van Swieten (1700-72), a pui>il and friend of Boerhaave, went to Vienna in 1745 and introduced clinical instruction, but the only surgeon of repute there in 1780 was Ferdinand von Leber, who is principally known by the investigation which he made upon the use of torture in jurisi)rudenee. In 1785 the Military Medico-Chirurgical Akademie was founded by the emperor Joseph II. and placed under the direction of Brambilla, the object being the «nne as that of tlie Berlin Pepiniere. It was connected with a hos- pital of twelve hundred Ix'ds, and received one hundred pupils, of whom twenty-four were residents in the house. The course of study was two years, and after passing the examination the student received the degree of doctor in surgery and the first vacant position in a regiment. Giovanni Alessandro Brambilla (1728-1800) was an Italian who had studied in Pavia, and liecame a surgeon in the Austrian army and a special favorite of the emperor. He pi-epared the Insfnikiion fur die Profes- soren der k. h. chirurf/isriioi Militurakademie (Wien, 1784, 4to) and the Instrukfiun fur das k. k. Jlilitdrnpital zu Wicn (Wien, 1784, 4to), which are curiosities in literature. The subjects and the order of the subjects to be taught are scheduled for each professor. He also published a large atlas of engravings of surgical instruments and a history of dis- coveries made by Italian anatomists and physicians, and exerted a power- ' For details as to the military surgery of these times see Die Krieys-Chiruryie der letzcn ISO Jahre in Preussen, von Dr. E.

A proteg6 of Branil)illa was Joh. Nejionuik Ilunezovsky (1752-98), a barber's apprentice, who in 1781 was ap])(>inted professor in the military medical school at (iumpendorf, and published a compendium of surgical operations in 178'), of which there were three later editions. iVt the commencement of the eiffhteenth century Holland was a great centre of medical instruction : Boerhaave had introduced clinical teach- ing at Leyden, where Bidloo was also lecturing ; Ruysch and Rau were teaching in Amsterdam, and all who desired a complete education in surgery visited these schools. Frederik Ruysch (Ki.'^iS-l 731 ) commi'nceil teaching anatomy in Ley- den in l()(j(), and became famous for the jicrfection of his anatomical preparations, and especially for his injected prejiarations. His collection was purchased by the czar, Peter the Great, but a part of it was lost before it reached St. Petersburg. His numerous essays relate chiefly to anatomy, iiut contain some surgical observations. Joh. Jac. Rau (l()(iS-1719), a native of Baden and an a])])rentic.e of a barber surgeon in Strasburg, studied at Leyden and Paris and settled in Amsterdam, where he gave lessons in anatomy and surgery, to the great dissatisfactiou of Ruysch. Having learned from Frere Jacques his method, he improved ujion it and acquired great fame as a lithoto- mist, but kept secret the details of his method, which was p7-ol)ably the lateral o]teration. He wrote nothing of importance, but had many dis- tinguisiied pupils. To this period belong Abram Titsingh (1685-?) of Amsterdam, city surgeon, surgeon of the admiralty, and master of the Surgeons' Guild, who wrote works on lithotomy, spina l)itida, venereal diseases, etc. which were valuable in their day; Joh. Daniel Schlichting (1703-?), a lecturer on anatomy and surgery in Amsterdam in the middle of the century, said to have been the first to perform neurotomy for neuralgia of the fifth pair; Jos. Monnikhof (1707-87), appointed herniotomist of Am- sterdam in 1752, who in 1775 published statistics of one thousand cases of hernia, the first collection of this kind which had appeared ; and Charles Faudacc] (1691-175 ?) of Namur, who studied in Paris under Petit, and published Rtlftcxiom sur lex ]j/ai/cx, etc. (Nanuir, 1735), and Noarcau traite dcs pinics crarmcs-d-fci( (Namur, 174(i). In Ghent the leading surgeon was Joh. Palfyn (l(i5O-1730), educated in Paris, master of the Barber-Surgeons' Comj^any in Ghent in 1698, and professor of anatomy and surgery in 1708. He is best known by his Anatomic Chirun/ienlc, first published at Paris in 1726, and the first treatise with the title of " Surgical Anatomy." In the last half of the century the most celebrated teacher in Hol- land was Peter Camper (1722-89), a native of Ijeyden, who became pro- fessor of anatomy and surgery in Amsterdam in 1755 and professor in Groningen in 17(33. He was one of the most learned men of his time, and a voluminous writer on anatomy, pathology, and medical jurispru- dence. His treatise on calculus (1782), his dissertation on fracture of the patella and olecranon (1789), and his Irones hcrniarum, ])ublished after his death by Soemmering, are valuable contributions to surgical literature. Among the Italian surgeons of the eighteenth century the best THE HISTORY AXD LITERATURE OF SUROERV. SI known are Benovoli, tlu' two Xannonis, Lancisi, A^alsalva, Tacconi, ami Bertrandi. Antonio Jiencvoli (1(385-1756), a surgeon of Florence, discovered in 1722 that eataract is an opacity of the lens, and published his I>l-tcorsi (U chirurr/id in 1750. He discovered the principle of treating stricture of the urethra by dilatation. Angelo Xannoni (1715-90) studied in Florence under Bcnevoli, and afterward in Paris and Rouen, and became chief surgeon of the hos- pital Santa Maria Xuova in Florence, attaining great rejiutation. His principal works are Trattafo chirtdr/ico sopru la ficiDpHcita del iiiedicnre i malt d'aftenenza della chirurgia (1770) imd Jlemorie sopra aleani ca-d rnri di chirurqia (1776). Lorenzo Nannoni (1749-1812), son of Angelo, studied under his father, and became surgeon to the Hospital of the Innocents in Flor- ence, where he g-ave clinical teaching. His ])rincipal work is Trattafo delle malcric cliirinr/ichc, tie. (2d ed. •'} vols., 1793-94). Giovanni ilaria Lancisi (1654-1720), professor of anatomy at Rome and physician to Popes Innocent XL and XII., is best known as an anatomist, but in his De molu cordis et aneurt/smatihiis, first published after his death in 1728, and in four later editions, he first clearly pointed out the difference between true and false aneurism. Antonio Maria Valsalva (1666-1723) studied at Bologna, graduating in 1687, and became professor of anatomy in the university and sur- geon to the Hospital of the Incurables in 1697. His chief work was De awe humana tractatus (1705). Gaetano Tacconi (1689-1782), a native of Bologna, succeeded Val- salva as professor, and was surgeon to the hospital Santa Maria. He wrote Kofizia dclla fcrifa e della ciira chlrurglca seguita, etc. (1738), and De rarls qnihuftdatn hcrniis, etc. (1751). Giovanni Ambrogio Bertrandi (1723-65), son of a surgeon, studied at Turin and Paris, and in 1758 succeeded Lotteri as professor of surgery at Turin. His principal work is his Trattato delle operazioni di chi- rurgia (2 vols., 176."?), which ]iassed through several editions and was translated into French and German. His collected works, Opere an(doiiiiche e ccrusiche, w'ere published after his death in fourteen volumes (1786-1802). At the beginning of the eighteenth century there were few edticated surgeons in London, and still fewer in the provincial towns ; there was no special instruction in siirgerv to be obtained except through appren- ticeship ; and the facilities for studying anatomy were extremely limited.' When the monasteries were broken up by Henry VIII. the hospitals, which had previously liclongcd to the Church, became the proj)erty of the government. St. Bartholomew's was refounded in 1544, and placed under the superintendence of Thomas Vieary. This hospital had one physician and three surgeons, and these allowed tlieir pupils and appren- tices to attend and witness the practice. In 1()62 there is mention of the presence of such students, hut no formal system of lectures or teacli- ing seems to have existed until after 1734, when leave was granted for ' See The present state nf chyrurgeri/, by T.

At St. Thomas's Hospital tlie first mention of an ap])rentiee in the books is in 1561. The Barber Surgeons' Company was diss;itisfied with the teaching in St. Bartholomew's and St. Thomas's hospitals, as it was losing money thereby, and in 1695 it made a special investigation into the complaints as to the manner of teaching in these hosjMtals, tlie sur- geons to which declared that they had never taken an ajjprentice for a less term than seven years, but that some of the apj)rentices of other sur- geons were allowed at times to witness their practice. In 1702 the gov- ernors of St. Thomas's Hospital took the matter of teaching into their own hands, and passed a law forbidding ])U])ils or surgeons to dissect without permission of the treasurer. In 1703 it was resolved that no surgeon should have more than three " Cubbs ;" in 1758 this term was altered to that of " Dressers." Lectures on anatomy and surgery began with C'heselden about 1720, and the Anatomical School may be said to have been fairly established about 1780.' At the London Hospital the entry of the first student was in 1742, two years after the commencement of the hospital, and the Medical School was fully organized upon the model of the Edinburgh Faculty in 1785. In the Orders of St. Bartholomew, dated 1633, it is directed " that no cliirurgeon, or his man, doe trepan the head, dismember, or j)erform any great oper'con, but with the approbation or by the direction of the doc- tor." Special operators were appointed to cut for the stone at the hos- pitals, a Mr. Mullins doing this for St. Bartholomew's and St. Thomas's. The ^ledical School of Guy's Hospital dates from 1769, in which year a resolution was jiassed by the governors that all surgeons of the hospital should occasionally give lectures to tlie pupils. It is also noted : " No persons are to be entertained as pupils but such as have served five years to a regular Surgeon or Apothecary." At this time the schools of Guy's and of St. Thomas's were united, the surgical lectures being given at St. Thomas's and the medical at Guv's, and the two M-ere known as the "United Hospitals." ^ The ill-assorted union of sury-eons and barl)ers formed by the act of 1540 was by no means harmonious, but the surgeons were unable to get rid of the barbers imtil 1745, when they agreed with Mr. Ranby, Serjeant surgeon to the king, that he should procure the act of Parliament desired, and that in return lie should be made a member and be elected as master. The act of 1745, incorporating the "Masters, Governors, and G(aiinion- alty of the Art and Science of Surgeons of London," pro^•ided that it should be governed by a " court of assistants, composed of twenty-one members, whose office was for life, and who filled their own vacancies by election from the freemen of the comjiany." Ten of this court of assistants were to be " examiners," whose office was also for life, and it was a penal offence for any one to practise surgery in London or within seven miles of the same without having been duly examined and licensed, ' See Prospectus, 1877-78, p. 11.

THE HISTORY AXD LITERATURE OF SURGERY. 83 except tliat the rights of members of the College of Physicians to do so were not to be interfered with. The surgeons on their separation from the barbers took nothing witii tliem except the Arris and Gale becpiests ; tiie iiall, HItrary, and plate remained with the barbers, and the new com- pany had to i)rovide a building lor itself. The condition of the company in 1790, as stated by ISIr. Gunning, the master of the company, in his address at the close of his term of office, was as follows : " You have a theatre for your lectures, a room for a Library, a connnittee-room for your Court, a large room for the recep- tion of your committees, together with the necessary accommodation for your Clerk Your theatre is \\ithout lectures, your library room without books is converted into an office for your clerk, and your com- mittee room is become his parlour, and is not always used even in your common business, and when it is thus made use of it is seldom in a fit and proper state." The next thing tliat appears in its history is a charter by George III., dated 1800, for consolidating tlie Royal College of iSur- geons of London, in the preamble of which it is stated that "we are informed tiiat the said Corporation of Masters, Governors, and Com- monalty of the Art and Science of Surgery of London hath become and is now dissolved." This charter of 1800 simply reiterates the act of 1745. Turning now to Scotland, we find tiiat, in 1694, Dr. Archibald Pit- cairn returned to Edinburgh from Leyden and endeavored to establish a medical scliool, which lie intended, if possible, should surpass tiiat of Leyden ; and his first step was to induce a surgeon named Monteith to apply to the town council for a grant of dead bodies. As soon as the other surgeons heard of this, tiiey also applied for tiie .same privilege. The privilege granted to the surgeons had a clause to the eftect " that the petitioners shall before the term Michaelmas, 1697, build, repair, and have in readiness one anatomical theatre, M'here tiiev shall once a year (a subject ottering) have one public anatomical dissection, as much as can be shown upon one body, and if the ftulzie, this presents to be void and null." This condition was complied witli, and as the grant required that the body should be buried within ten days, tiie surgeons selected ten of their number, termed " operators," each of wiiom lectured one day on certain specified parts. In 1705 this .system was changed, and one surgeon performed the duty, wiiile the town council made this same sur- geon professor of anatomy in the university. This was the commence- ment of the Medical School, altliough it was not until 1726 that it was fully formed througli the influence of John Monro, an army surgeon who had settled in Edinl)urgli in 1700. The leading surgeon in England in the first half of the eighteenth century was William Cheselden (1688-1752), a pupil of William Cowper, who began to lecture on anatomy in 1711 in his own house, and continued his teaching afterwairl at St. Thomas's Hospital, to which he was ap[)ointed assistant surgeon in 1718 and surgeon in 1719. In 1723 he published his Treatise on the high operation for the fitoiie. Soon after he gave up this and perfected liis "lateral operation for the stone," an improvement on tiie method of Frere Jacques and Ran, whicii soon became famous. He publisiied a paper in the Philosophical Transactions on the formation of artificial pujiil, wiiicli operation he was the first to 84 THE HISTORY AND LITERATUltK OF SURGERY. ]icrf()rm. In 1733 he became surgeon to St. George's Hospital at its loiiiidation, retired from St. Thomas's in 1738, and was one of the hist wardt'Ms of tlie 15arher 8ui'geoiis' ('ompany immediately before the sepa- ration of the surgeons and liaiiiei-s, whieii took place in 1744-45. His pupil, Sanuiel Sharp (1700-78), was elected surgeon to Guy's Hospital in 1733. His Treatise on the ojxrations of surgery (London, 1739 ; lOtli ed., 1782) and his Critical inquiry into the present state of sinyery (London, 1750 and 1761, and translated into French, S])anish, and German) were celeljrated in tiieir day, and the Critical iia/niry is still a most interesting book to the surgeon. He devised the cylindrical form of the crown of the trephine at jiresent used, and contributed to the knowledge of the anatomy of hernia. William Bromfield (1712-92), surgeon to St. George's Hospital and surgeon to the king, published his L'hirurgical observations and cases, in two volumes, in 1773. These contain a number of valuable improvements in surgical methods, particularly as to bilateral lithotomy and the com- pression of the subclavian artery above the clavicle on the first rib. He also clearly points out the proper manner of ligating the artery in ampu- tations, using the tenaculum to draw out the vessel, so that the nerve and other tissues should not be included, but he used a flat ligature. That he was a cool operator is shown in a case of lithotomy which he reports in the second volume at ])age 266, in which the intestines protruded into the bladder, and in which he first extracted three stones and then returned the intestines, with result of a perfect cure. William Beckett (1684-1738), a London surgeon, wrote Practical surgery illustrated and improved : being chirurc/ical observations .... made at St. Thomas's Hospital (London, 1740, 8vo), also A collection of chirur- gical tracts (London, 1740, 8vo), including a paper on new discoveries relating to the cure of cancers, published by him in 1711. Benjamin Gooch, a surgeon of the Norfolk and Norwich Hospital in 1771, published a volume of Cases and praciical remarks in surgery (London, 1758), and a collective edition of his works appeared in three volumes (London, 1792). He taught that in case of a wound of an artei'v ligatures must lie apjilied both aliovc and below the wt)und. John Douglas (?-1743) was a Scotch surgeon who gave private lec- tures on surgery and anatomy in London about 1720, and in the same year published an account of the performance of the high opera- tion for the stone under the title of Lithotoniia Donglas-fiana. He was conceited and quarrelsome, and jniblished two alnisive pamphlets on Cheselden, by whom he was com])letely overshadowed. His l)rother, James Douglas (1675-1742), was a jihysician who settled in London about 1700, and was a distinguished anatomist and obstetrician. He puljlished a Description of the peritoneum (London, 1730, 4to), in which he described the fold of the peritoneum which is still known by his name. To the first half of this century lielongs one of the greatest itinerant quacks known to history — viz. .John Taylor (1708-67), who styled him- self " Chevalier, ophthalmiater pontifical, imperial, and royal." He was born in Norwich, and in 1727 published a pamphlet on the mechanism of the eye and on cataract. This he dedicated to Cheselden, from whom he acknowledges that he had learned all that he knew about the matter, and, THE HISTORY AND LITERATURE OF SURGERY. 85 ■while tlie work was boastful, yet it was not more so than some otluT jmlj- lieations of that day. Soon after this period lie ai)pears to haye giyen up all idea of respectable practice, and tnvyelled far and wide oyer Europe, advertisinrtant, especially those on hernia, injuries to the head, hydrocele, and the disease of the spine still known l)y his name as " Pott's disease." His Treatise on ruptures was pub- lished in 175(3, his Practical remarks on the hi/drocelc, in 1762, and his Beniark.s on that kind of palst/ of the hirer linihs irliich is frequentljj found to accompany a curvature of the spine, in 1779. His Chirurgical works appeared in 1771, and there were four later editions, besides German, French, and Italian translations. Alexander Monro (1697-1767), a pupil of Cheselden and of Boer- haaye, became the first professor of anatomy in the Uniyersity of Edin- burgh in 1725; he also lectured on surgery and made great use of com- paratiye anatomy. He founded the Royal Infirmary and gaye clinical lectures on surgery, and was one of the best surgeons of his time. His writings relate chiefly to anatomy, but he also wrote important papers on aneurism, cataract, hernia, etc. He first tried to cure hydrocele by the injection of wine. His son, Alexander Monro [secundus] (1733-1817), succeeded him as professor of surgery, and held the chair until 1810, when he gaye it oyer to his son of the same name, Alexander Monro [tertius] (1773-1859), who resigned in 1846, the professorship haying thus been held by the three Monros for one hundred and twenty-one years. Although the chair was thus, after a fashion, hereditary, the talent did not descend to the third generation. The next name to be mentir)ued is that of a man whose works mark an epoch in the deyelopment of surgery — -John Hunter (1728-93), the yiituigest son of a Scotch fjirmer. His brother William, ten years older than himself, haying receiyed an excellent education according to the l)attern of that time, settled in London and began to lecture on anatomy •and surgery in 1746. In 1748, John Hunter, a rough, ignorant youth, decidedly addicted to low company and amusements, and not haying shown the slightest taste for study, joined his brotiier, and was employed by him as an assistant in the dissecting-room which he had just estab- lished. He soon showed that he had found his proper field of actiyity, and after one year's experience was able to take charge of the pupils and to direct their work. William Hunter was a good classical scholar and a cultiyated and 'polished mm of the world, being in all these respects a complete contrast to his brother, who decided in fayor of -surgery as a career, and studied under Cheselden and Perciyal Pi on amputation and the after-treedment (London, 1779), in which he recommended a method for obtaining a more complete covering for the end of the bone by cutting the mus- cles from below upward. Henry Park (1744-1831) was a student of Pott and Le Cat, and was THE HISTORY AND LITERATURE OF SURGERY. 89 surgeon of the Royal Intinnary at Liverpool from 17(17 to 1798. His name i^ connected with the histurv of resection of the knee and elbow. Charles White of Manchester pul)lished his Caneiiiii SitrtjiTt/ in 1770, and first excised the head of tiie luuncrus in 1768. Robert Mynors (17oy-18U6), a surgeon of Bmningham, published his Practical observations on amputation in 1783, and his History of the practice of trephining the skull, etc. in 1785. William Hey (1736-1819), a distinguished surgeon of Leeds, pub- lished in 181)3 his Practical Observations in Sure/eri/, which passed through two later editions, and is still worthy of consultation. He described and named fungwi hamatodes. His name is connected with the form of saw devised by him for use in case of fracture of the skull, and with a mode of partial amputation of the foot. At tlie end of the century the leading surgeons in Edinburgh were Benjamin and John Bell. Benjamin Bell (1 749-1 8()()) was a \m\)\\ of Monro, and l)ecame a sur- geon of the Royal Infirmary in 1772. In 1778 he publislied A treatise on the theory and management of idcers, etc., which went through nume- rous editions and translations. His System of surgery (6 vols., Edin- burgh, 1783-87) also passed through many editions, and was trans- lated into German and French, being the favorite systematic treatise for the next twenty years. He insisted strongly on the im])ortance of saving skin in amputations and operations for the removal of tumors, in order to leave as little as possible of the surface of the wound exposed. John Bell (1765-1820) graduated in medicine in Edinburgh in 1779, and in 1790 opened ii private school for anatomy, surgery, and obstetrics. He was ambitious and energetic, and unsjiaving in his criticisms of his seniors, Monro and Benjamin Bell, thus causing o])])osition to his school, which, however, was popular and successful. His brother Charles was of great assistance to him in this enterprise. He published a treatise on anatomy which went through many editions : Discourse on the nature and cure of wounds (Edinburgh, 1795, with several editions and trans- lations) and The Principles of surgery (3 vols., London, 1801-08, 4to), remarkable for the beauty of its engravings. He was the leading ope- rating siu'geon in Edinburgh for nearly twenty years. As the result of a bitter controyersy with Gregory the number of surgeons at the Royal Infirmary was in 1800 limited to six, and Bell, with others, was excluded, and thus lost the opportunity for clinical teaching. The story of the rise and progress of surgery in Ireland is told in the History of the Royal College of Surgeons in Ireland and the Irish Schools of Medicine, by Charles A. Cameron (Dublin, 1886). In 1446, King Henry VI. established, by royal charter, a fraternity or guild of barbers for the ])romotion and exercise of the art of chirurgerv. In 1572, Queen Elizabeth granted a second charter to the l)arbers and surgeons, ordering that they should be called the " Master Wardens and Fraternity of Barbers and Cliirurgeons of the Guild of Saint Mary or Magdalene in our city of Dublin," and a third charter was grante(l in 1687 by James II., giving them full power of the guild over barbers within six miles of Dublin. There were, iiowever, a certain number of surgeons m4io had no connection of any kind with the company, being army surgeons, or men of liberal education who had studied in the uni- 90 THE HISTORY AM) LITERATVnE OF SURGERY. versities. In 1745 the company hcfi;an to disintofrrate, and in 1784 the union between the harbcr.s and tlie surgeons was praetieally dissolved by the creation of the Royal College of Surgeons in Ireland. The beginning of teaching in I)ul)lin is due to Sir Patrick Dun (1642-171."}), president of the College of Physicians in Ireland, who left a becpiest for "one or two Professors of Physiek to read ])ul>lick Lectures and make publick Anatomical dissections of the several ])arts of the human Body or Body's of other animals, to read Lectures of Osteolog}*, Bandages, and operations of Chirurgery, to read Botanic Lectures, Demonstrate Plants puhlickly, and to read Publick Lectures on Materia Medica, for the Instruction of Students of Physiek, Surgery, and Pharmacy." The teaching did not actually liegin until 1744. The first surgical work pulilished in Ireland apj)ears to be A Concise and Impartial Account of the Advan- tages avisiitg to the Public from the general use of a New Method of Am- putcdion (DuhWn, 1703, pp. 13). The second was Ohserixdions on Wounds of the Head (Dublin, 1776, pp. 177). This was published anonymously, but a])peared in a second edition in 1778 under the name of the author, AVilliam Dease (1752-98), who was one of the most energetic founders of the Royal College of Surgeons, and one of the first to lecture in it. He was a very successful teacher, and in addition to his work on wounds of the head he published An Introduction to the Theory and Practice of Surgery (London, 1780, 8vo) and a work on midwifery ^\hich became a popular text-book. In 1765, Sylvester O'Halloran (1728-1807), a surgeon of Limerick, Avho had studied in Paris, London, and Leyden, jiublished at London A Complete Treatise on Gangrene and Sphacelus ; vitlt. a new Method of Amputation, which was a valuable contribution to the literature of these subjects. The Nineteenth Centuky. The salient points in the history of surgery in the nineteenth century are the discovery of anassthetics ; the establishment of aseptic and anti- septic surgery upon the scientific foundation of the new science c)f bacteri- ology ; the development of conservative surgery in the treatment of diseases and injuries of the extremities and of plastic and orthopicdic surgery into a specialt}' ; the rise and progress of abdominal and intracranial surgery; the entrance of two new nations, the United States and Russia, into the field of surgical discovery, literature, and teaching ; the change in the methods of educating surgeons ; the formation of surgical societies and associations ; and the cosmopolitan character of the art developed by rapid international communication and liy periodicals. The founding of nuiseums like those of Hunter and Dupuytren, the removal of restrictions on the study of anatomy, the great advances made in pathological anatomy and ex])eri- raental pathology, and the development of oi)hthalmology, otology, gynsecology, dermatology, and laryngology into their present highly specialized forms, have also exerted a strong influence upon surgery and the work of the general surgeon. With the increasing accunuilation of the people in cities have come increased demands and o|)portHnities for surgeons, for increase of hospi- tals and medical schools, for skilled nursing, ingenious mechanics for the making of instruments and apparatus, and, in short, for many means of THE HISTORY AND LITERATURE OF SURGERY. 91 carrj-ing out suggestions for improvcnieuts through tlic aid of competent assistants. More progress in the art has been made since liSUO than iiad been made in the two thousand years preceding that date, and this has been largely due to work done in the dissecting-room and in the laboratory. Consider for a moment some of the differences between the resources of the surgeon of ISOO and those of the surgeon of tlu' present day. The surgeon of 1800 had little more knowledge than had ilippocrates of the chief causes of danger after operations, such as suppuration, pya^nia, or tetanus, and groped wildly for means to avoid them. He had no clinical thermometer, and could only guess at temperature and fever ; no hypoder- mic syringe ; no anaesthetic ; no definite knowledge of the imjKirtanee of blood-saving or of the best means of doing it. He knew nothing of plastic surgery, of tenotomy, of the ophthalmoscope, or of the use of the niicro- .scope in diagnosis, and had only just learned how to ligate arteries and to treat ordinary wounds in a simple and sensible way. The really great surgeon of that day who was bold, cool, and skilful could perform most of the great oi)erations, such as amputation, ligature of hirgo arteries, removal of tumors, Csesarean section, and the like, but such men were few and far between. At the beginning of the century London was the centre of surgical improvement and of surgical teaching, and the leading siu'geons at that time were Abernethy, Cline, Blizard, Home, Astley Cooper, Lawrence, and Wardrop. The first four of these have been referred to in a pre- vious section. Astley Paston Cooper (17(38-1841), a native of Norfolk, was appren- ticed in 1784 to his uncle, William Cooper, surgeon to Guy's Hospital, and was soon transferred to Cline, then surgeon at St. Thomas's. He attended John Hunter's lectures and spent one winter at the Edinburgh Medical School, was appointed demonstrator of anatomy at St. Thomas's in 17851, and two years later became joint lecturer with Cline in anatomy and surgery. In 1800 he was appointed surgeon to Guy's on the resig- nation of his uncle. In 1805 he ligated the common carotid for aneurism, and in 1817 the abdominal aorta. In 1820 he performed a simple opera- tion on King George IV., which resulted in his being made a liaronet. In 182.5 he resigned his lectureship at St. Thomas's and induced the for- mation of a separate medical seliool at Guy's, in which his pupil, Aston Key, lectured on surgery, and his ne]iiiew, Bransby Cooper, on anatomy. He was an extremely skilled anatomist, and some of his most valuable contributions are connected with his work in this direction. Among them may be mentioned his treatises on hernia (in two parts, 1804—07), the second edition of which ap])eared in 1827, the illustrations to which are said to have been so expensive that he lost a thousand pounds by the publication. His book on Dislocations and Fractures of the Joints was published in 182"J; his Lccfures on the Principles and Practice of 8urf/eri/, with additions by Tyrrell, in three volumes, in 1824—27 : the eighth edition of this appeared in 18;17 ; and his Illustrations of Dis- eases of the Breast, Part I., in 1829; his observations on the Structure and Diseaiies of the Testes in 1830; and his work on the Anatomy of the Breast in 1840. He seems to have read little, his books contain few references to the work of other men, and his reputation and iuHuence 92 THE HISTORY AND LITERATURE OF SURGERY. were due more to his personality and his great skill as an operator tiiaii to his ('ontril)iiti()ns to science or practice. William Lawrence (17S.')-1.S()7), tlie son of'a surfruoii, was a pupil of Abernethy and liis demonstrator of anatomy for twelve years. He became a member of tiie Collejic of Surgeons in 1805, won its prize for an essay on hernia in 18()(), was ai)pointed assistant surgeon to St. Bar- tholomew's Hospital in 181.3, and in 1815 became professor of anatomy and physiology at the College of Surgeons. His lectures were considered to flavor of infidelity, and led to a sharp controversy, which ended by his recanting the objectional)le opinions and withdrawing his l)ook, On the Hixtory of Man, from sale as far as he could. He was connected with the Aldersgate ]\Iedieal School, and in 1823 succeeded Aliernethy as lecturer on surgery at St. Bartholomew's. His principal contributions to surgical literature are his Trcafii^e on Diseases of the Et/e (1833) and his Lectures on Suiyeri/, jtublished in 18rotiier of John Bell of Edinburgh, under whom he studied and whom he soon began to assist in the teaching of anatomy. In 1804 he went to London, where he began to teach in his own house in 1807, after which he associated himself with Mr. Wilson in the Great Windmill Street School, where he came into com- petition as a teacher with Cline, Cooper, and Abcrncthy, and met with great success. In 1812 he began to deliver clinical lectures in the INIid- dlesex Hospital, to whi<'h he was appointed surgeon in 1814. In 1836 he accepted the chair of surgery in the University of E(linl)urgh, wliich he held until his death. His publications were voluminous, and include his System of Operative Surgery (2 vols., 1807-09), his paper on Gunshot Wounds (in 1814), his Surgical Observations (2 vols., London, 1816-18), and his Illustrations of the Great Operations in Surgery, etc. {in 1821). His fame, however, is 'mainly due to his ])a]K'rs relating to the ner- vous system, the result of careful and long-continued experimental work. His Idea of a JVew Anatomy of the Brain, printed in 1811, is a pamphlet of 36 pages Avhich forms an epoch in the history of discoveries relating to the structure and functions of that organ. He was a skilled artist, a dexterous operator, and a conscientious and popular teacher, whose fame has increased instead of diminishing; since his death. 94 THE HISTORY AND LITKHATUIiE OF SURGERY. Bcnjaiuin Travel's (ITSS-LSoS) was a pupil of Astlcy Cooper, pro- sector of" anatomy at (Jiiy's Hos])ital, and surgeon of St. Tliomas's Hos- pital in 1815. He was a skille(l oplitlialniolof^ist, and liis tS}/iioj)xin of the Diseases of tlie ]'Ji/c (1X20) was tlie hest systematic treatise on that subject which had yet appeared in Eni;lish. His tastes led him to the scientific rather than to the practical aspect of surgery, and his treatises on C'on-\ dituflonal Irritation (1824), A further Inquiry concerninr/ Constitutional Irritation and the J\ifhologi/ of the Nervous Si/stetn (18.34), and The Phi/sioloffi/ of Inflainination (1844) are specimens of physiologico-])atli- ological investigation of the highest order of merit. He contributed some valuable papers on aneurism and the ligature of arteries to the Medieo-chirurgieal. Transactioyis, and one on wounds of the veins in the 8urf/ieal Essai/s, ])ul)lished by Astley Cooper and himself in 1818-19. He introduced tiie use of mercury in non-specific iritis and in other forms of inflammation. Of all the English surgeons of this period, there are none wiiose writings are more interesting to-day than are those of Travers. In Edinburgli there was no surgeon of special note engaged in teach- ing after John Bell was excluded from the infirmary and gave up his school. No separate chair of surgery was established in the university until 1831, owing to the persistent opposition of the second Monro, who claimed to be professor of surgery as well as of anatomy. A chair of surgery was instituted in the College of Surgeons in 1804, which was maintained until the chair was created in the university in 1831, and this was filled by Dr. John Thomson (1765-1846), who became surgeon of the Royal Infirmary in ISDO, and began to give clinical lectures therein on surgery in the private theatre in 1801, this being then the only sejiarate course on this subject given in the city. In 1806 a chair of military surgery was instituted in the university, to which Dr. Thomson was appointed. His Lectures on Infiammation, etc. (Edinburgh, 1813) passed through several editions and translations, and his Report of Ob- servations made in the British Military Hospitals in Belgium after the Battle of Waterloo, etc. is of interest to army surgeons. A chair of clinical surgery was created in the university in 1803, Avhich was filled by the appointment of James Russell, a surgeon of the Royal Infirmary, who published in 1794 A Practical Essay on a certain Disease of the Bones termed Necrosis (Edinburgh, 8vo), and in 1833, after his retirement, Observedions on the Ti'sticlcs. Sir George Ballingall (1780-1855) entered the army in 1806, and became professor of military surgery in the university in 1823. His principal work is his Outlines of the course of lectures on Military Sur- gery, etc., published in 1833, which reached a fifth edition in 1855. Here also may be mentioned John Hennen (1779-1828), a distin- guished English military surgeou, a native of Ireland, who studied in Dublin and Edinburgh, and entered the army in 1800. His chief work is Observations on .sy>//;<' important poiids in the practice of 3Iilifary Sur- gery, etc. (Edinburgh, 1818), and subsequent editions, called Principles of Military Surgery (Edinburgh, 1820). In Glasgow at the beginning of the century the leading surgeon was John Burns (1775-1850), M'ho was the first lecturer on anatomy who was unconnected with tlie university. His Principles of Surgery (2 vols., THE HISTORY ASD LITERATURE OF SURGERY. 95 Loiiilon, 1829-38) was dry ami lunl no success, but his Principles on 3Ii(ltrif('ri/ reached a tenth edition. In I8I0 he was appointed Regius professor of surgery in the University of Ghisgo\\-, and held this position until his death. Allan liurns (1781-181o) was a brother of John, whose demonstrator he became in the anatomical school. He first described the falciform process of the fascia lata in its relations to femoral hernia in a pa])er wliich he puljlished in the Edinliuiyh Mviliail Journal in 180(5. His Observationn on the Surr/ieal Anatomi/ of the J [cad and Neck (Glasgow, 1811) is a valuable surgical work, which contains, in addition to the anatomy, accounts of numerous cases of tumors in this region, a discus- sion on the treatment of aneurism, etc. He suggested the ligature of the innominate artery, and it was this suggestion which led to the first performance of the operation by INIott in 1821. Between 1825 and 1840 four surgeons in Edinburgh became distin- guished, and two of them were transferred to London to take high places there. These four were Lizars, Liston, Fergusson, and Svme. John Lizars (1783—1860) was a pupil of John Bell, and began to teach anatomy in a private school in 1815. In 1831 he became pro- fessor of surgery in the Royal College of Surgeons. He was the first in Scotland to ligate the innominate, and the second to perform ovariot- omy, an operation which became known maiidy through his Obsermtions on Extirpation of Disea> this teaching in favor of Syme and devoted himself entirely to surgery. He became surgeon of the North London Hospital and professor of clinical surgery in University College, Loudon, in 1834, and rapidly achieved a great success. He was possessed of great per- sonal strength and was a brilliant operator, having the reputation of being the most dexterous surgeon of his time. His method of fiap- amputatiou became very popular, and he made numerous contributions to the surgery of ani])utation, aneurism, lithotomy, and lithotrity. He would amputate the thigh with only the aid of one person to hold the limb and tie the ligatures, compressing the artery with his left hand, using no tourniquet, and doing all the cutting and sawing witli the right. A large part of his skill and success was due to his knowledge of anatomy, wliich he kept up by dissections throughout his life. He excised the upper jaw for a formidable tumor in 1836, and the success in this instance brought to him a crowd of cases. His rashness is exempli- fied in the celebrated case in which he punctured an aneurism of the carotid, su])])()sing it to'be an abscess, although his house-surgeon had told iiim that the tumor ])uls;ited. His principal ])ublications were his Elcnient.s of ,S»;Y/f/v/, published in l.S;51,and his Practie(d Surgery, in 1837, both of which works went through several editions. William Fergusson (1808-77), a native of Scotland, was educated at Edinburgh, being a ])upil of Robert Knox. In 1831 he was elected surgeon to the Edinburgh Royal I)ispens;iry, being at this time lectur- 96 THE msTonr am) liticrature of simnEnr. ing on surgical anatomy in association with Knox, and was tiic first to ligate the subclavian in Scotland. In 1840 he accepted the professor- ship of surgery at King's College, London. In ISo;") he was a|)pointed surgeon extraordinary, and in LSIw serjeant surgeon to tiie queen. For many years he was tiie leading surgical operator in London. He resigned his professorship of surgery in 1870, but remained clinical ])rofessor of surgery and senior surgeon at King's College Hospital until his death. He was created a baronet in 1866. His special contributions to the art were largely in the line of what he called "conservative surgery," a term which he first apjilied in 1852 to the avoidance of anqintation l)y means of resections and to the removal of no more than is alisolutely necessary in cases of diseases of the bones. His name is especially asso- ciated with operations of hare-lip and cleft palate, \\'itli operations on the jaws, the excisicm of joints, and with lithotomy and lithotrity. His principal contribution to literature is his System of Practical Siirf/crt/ (London, 1842; 5th ed. 1870). He also contrilnited many valuable papers to the periodicals. His lectures on the Pror/rcss of Aiuitomj/ and Surgery during the Present Century (1867) are extremely interesting to the student of the history of surgery. James Syme (1799-1870) was a jiupil of Dr. Barclay, and when only nineteen years old was entrusted with the charge of his cousin Listen's anatomical rooms, in which he began to teach in 1S22. In 1825 he began to teach surgery, but, having quarelled with Liston, he had no chance to obtain an appointment in the Royal Infirmary, and therefore started a private hospital. When he succeeded Kussell in the clinical chair in the university, he became one of the surgeons of the infirmary in 1833, and after Liston went to London in 1834 the greater part of the operative surgery of Scotland fell into his hands. In 1831 he pub- lished his treatise on the Excision of Diseased Joints, which was the fir.st systematic attempt to show that excision ought, in most cases, to super- sede amputation, and it had the greatest influence in bringing about this change in practice. The first edition of his Principles of Surgery was published in 1822 ; the fifth edition in 1863. This is an extremely con- cise work, and the fifth and last edition is smaller than the first. In 1847 he pul)lished his Contributions to the Pathology and Practice of Sur- gery, in which he gives an account of the first eight cases of amputation at the ankle-joint by the method which is still known by his name. The date of his first case of this kind is September 8, 1842. In 1847 he accepted a call as surgeon to LTniversity College, London, on the tleath of Liston, but he did not find the place satisfactory, and four months later he returned to Edinburgh. He was a bold, cool, and skilful operator, but not a rash one. Among his most remarkable operations may be mentioned those for aneurism by incision of the tumor and ligations above and below, M'hich operation he performed in cases of aneurism of the carotid, the axillary artery, and the iliac artery. In 1835 the greater part of the medical teaching in London was still given in private schools having no connection with hospitals, the oldest and best known In'ing the Windmill Street and Aldersgate Street Schools. The Great Windmill Street School was established by William Hunter about 1746, and numbered among its teachers the two Hunters, Baillie, Cruikshank, ^\'ilson, ]Mayo, Shaw, Brodic, Charles Bell, Carpue, and THE HISTORY AM) LITERATURE OF SUROERY. 97 Cffisar Hawkins, hut was linally destroyed by the estahlishment of tlie I^oiidon University in the vicinity of the Middlesex Hospital in LS3G. The Aldersgate School was also of old date, and nnnihered ainono- its teachers ^^'ardrop and Lawrence. The hospital schools of Guy's and St. Thomas's, which had been nnited in 17upil of Sir William Lawrence, l)ccame demonstrator of anatomy at St. Bartholomew's in 1846, assistant surgeon to the hos])ital in 1852, and surgeon and lecturer on surgery in 1863. He contributed many ])aj)ers to journals and transactions, and is best known by his treatise On joint (Jiseascx, jjublished in 1867. John Marshall (1818-91), a student and assistant of Liston, became siu-geon of University College Hospital and professor of surgery, in which position he gave sjiecial attention to physiology and pathology and to the views of Virchow, C'ohnheim, and other German authorities. During the latter part of his life he was president of the General Medical Council. His principal published work was his Outlines of phymology (2 vols., 1867). Alfred Poland (1822-72), a pupil of ]\Ir. Aston Key, became dem- onstrator of anatomy at Guy's Hos])ital in 1845, assistant surgeon of the hospital in 1849, and full surgeon in 1861. His Essay on gunshot wounds and their treatment received the Jacksonian prize at the College of Surgeons, and his paper, Tlie injuries and wounds of the abdomen, gained for him the Fotherg-illian medal of the Medical Society of Lon- don. He contributed many papt'rs to Guy's Hospital Reports and also to the weekly medical journals, but wrote no important separate work. John Cooper Forster (1823-86), the son of a medical man, studied at Guy's, where in 1850 he was ap])ointed demonstrator of anatomy, in 1855 assistant surgeon, and in 1870 surgeon, which latter position he resigned in 1880. He performed the first gastrostomy in England in 1858. His only pul)lished separate work was on The sun/ieal diseases ofrhifdren (1860). George William Callender (1830-79) studied at St. Bartholomew's, where he became assistant surgeon in- 1861, surgeon in 1871, and lec- turer on surgery in 1873. He contril)uted largely to St. Bartholomew's Hospittd Beports, o{ which he was surgical editor from 1865 to 1873, and also furnished many papers and notes of clinical lectures to journals and transactions. The Transactious of the Royal iSoeiety i'or 1869 con- tain an important i)aper by him on " The formation and growth of the bones of the human face." He \\as one of the first to carry out in detail asepsis in surgery, as contradistinguished from antisepsis. His only separate work was Anatomy of the parts concerned in femoral rupAure (1863). Peter Charles Price (1832-64), the son of a physician, studied at King's College, and became assistant to Mr. Fergusson in 1854. He was appointed assistant surgeon to King's College Hospital in 1861. He paid special attention to the pathology and surgery of the joints, and more THE HISTORY AXH LITERATURE OF SURGERY. 103 espt'c'ially to tlie diseases of the knee and their treatment hy excision. His principal M-ork is .4 Description of the diseased conditiuim of the knee- joint wltieh require amputation of the limb, and those conditions u^hich are favorable to excision of the joint, etc., pnl)lisiied after his death in 18(55. Charles Frederick Maunder (18:32-7!l) studied in Bristol, London, Edinburgli, and Paris, served in the army dnrino- tlie Crimean War, and was appointed assistant surgeon to the London Hospital in l!S()(), and surgeon in 1869. He was a bold and skilful operator, and his text-book on operative surgery (1860; 2d ed. 1873) was an excellent manual. "William Frederick Teevan (1833-87) was educated at University College, and was elected assistant surgeon of the West Ijondon Hos- pital for Urinary Diseases in 1866, after which he devoted himself more especially to the surgery of the genito-urinary organs. He is best known by his work. Inquiry into the cuus(dion, diagnosis, and treatment of fractures of the internal table of the skidl (1864), which is a classical work of reference on this subject. Marcus Beck (1843-93) studied at Glasgow under Mr. Joseph Lister, his cousin, and at University College, Ijondon, and in 1873 was a])pointed assistant surgeon to University College Hospital, becoming surgeon in 1885 and lecturer on surgery in the same year. He was one of the first to introduce antiseptic methods in surgery in London, and, though not a voluminous writer, made some valualile contriliutions to surgical litera- ture, including a paper on " Consecutive nephritis," or surgical kidney, in Reynolds's Si/.stem of medicine, and a jjart of the report on pvitmia and septicemia in the Transactions of the Patholof/icul Society for 1879. Frederick LeGros Clark (1811-92), an apprentice of Travers, stud- ied at St. Thomas's Hospital, beginning in 1.S27, and was appointed assistant demonstrator of anatomy in 1830. In 1839 he became lec- turer on anatomy and ])hysiology, in 184.'> assistant surgeon to the hos- pital, and in 1853 full surgeon, which office he retained for twenty years. When ^Ir. St)utli resigned the chair of surgery Mr. Clark succeeded him, and retained the office until he retired from the hospital in 1873. His principal work was his Lectures on the jvinciples of surgical diagnosis : e.speci(dfy in relation to sitock and visceral lesions (London, ]S7t); 2d ed. 1872). A numlier of his papers in journals and addresses were collected and printed under the title of Papers on surgery, pathology, and allied subjects (8vo, London, 1889). The two greatest advances in surgery in the nineteenth century are the introduction of aniesthetics, which was due to American surgeons, and will l)e referred to hereafter, and the introduction of systematic and scientific antisepsis and asepsis in the treatment of wounds and the per- formance of surgical operations, which is due to an P]nglish surgeon. Sir Joseph Lister, who brought it into notice in 1867-68. Antiseptics <3f variinis kinds had been proposed and used by others prior to this date. Kiichenmeistcr 'of Dresden had reported good results from the use of carbolic acid in 1860 ; Lemaire's work on carbolic acid ap])eared in 1863; Cam|)bell de Morgan used chloride of zinc in 1866; but it was Mr. Lister who established the method on the basis of Pasteur's ex|K'riments showing that putrefaction is due to the action of micro- orgiuiisms, and who systematically sought for, and found, means to jire- vent the access of these micro-organisms to wounds or to destroy their 104 THE insTonr and litehatt're of ST'naEnY. vitality if tliov had already j^aiiicd adiiiissidti, and to do tliis with tlie least po8sil)le injuiy to tlic li\iii<;' tissues. The aetual eauterv and tiie boiling oil of the surgeons of the tifteenth and prior centuries were antiseptic, no doubt, as were also some of the multifarious wound-dress- ings in use since the days of Hippocrates ; but antiseptic surgery began with Mr. Lister, and its progress has lieen largely due to the scientific manner in which he ileveloped and expounded it. A\'ith tlie introduc- tion of Koch's method of t'lilturcs on solid or scnii-solid media, wliich is the fcnindation of the new bacteriology, has come a knowledge of the mode of development and of the results of the growth of some of these organisms which has already revolutionized operative surgery, and made obsolete and com])aratively useless a vast amount of surgical literature and statistics. An illustration of this is given in a compari- son of the results obtained by Liston in 1S44 with those olitained in the University College Hos])ital forty years later, contained in an address on surgery by John Marshall in the British Medical Journal (August 8, 1885, p. 235). He concludes that "injuries not involving a breach of the surface of the body, simple intlammations consecutive to these, or so- called idiopathic local intlanuuations whicli come under the care of the surgeon, such as sprains, simple dislocations, synovitis, orchitis, and other cases, were not less satisfactorily treated in 1844-45 than in 1883, and the progress of the patients toward recovery was quite as rapid, but that in eases of wounds and operations the diifcrence in fa\-or of the latter period is very striking." After the abolition of the medical faculties and societies iri France by the decrees of 1792 and 1703 the evil results of want of means for giv- ing proper medical instruction soon became evident from the fact that properly-qualified medical officers could not be found to supply the jilaces of those who died in the service of the armies of the Rejiublic. By direction of the National Convention a report was prejiared by the celebrated chemist, Fourcroy, on the best plan of organizing medical schools to meet this want, and in accordance with this report a law was passed in 1794 establishing medical schools at Paris, ]\Iontpellier, and Strasburg. The method taken to secure students was peculiar and effec- tual. From each district in France a young man between seventeen and twenty-six years of age, whose name had not been drawn in the first conscription, was selected Ijy the governmental authorities and forwarded at the expense of the State to one of these schools, three hundred being assigned to Paris, one hundred and fifty to Montpellier, and one hundred to Strasburg. Three years was the period of instruction alkiwed, and as soon as they were considered qualified they were sent to join the troops. These were really military medical schools analogous to that established at Berlin. They did not confer the doctor's degree, the object being simply to manufacture medical officers as soon as possible. After several changes the Paris school was definitely organized in 1804, and became a medical society as well as a teaching body, the object of the government being to obtain not only a medical faculty, but a scientific body which should be capable of giving advice to the government. The society part of this arrangement was dissolved in 1821 by the formation of the Academy of ]\Iedicine. In 1806 the Imperial University was created, and in 1808 the med- THE HISTORY ASD LITERATURE OF SURGERY. 105 ical school became its faculty of medicine. In 1822, owing to political trouljles, the Faculty of Medicine was suppressed, but it was re-estal)- lished in 182;^ with a change in a number of the professoi's, A. Duljois and Pelletan losing their chairs. In 1830 the Faculty of IMedieine was again reorganized, the acts of 1822 and 1823 being abolished and the old professors being again placed in their chairs, while at the same time the concours was again estal)lished as a means of tilling the professorships. Jules Rochard, in his Hisfnirc fJc la ehinnyic fraiujatse an .rl.v' siec/c (Paris, 1875), gives the most complete and satisfactory account of French surgery of the century, and his division of it into four periods will be followed in tliis sketch. At the beginning of the century the leading surgeons in Paris were Sabatier, Deschamjis, Lassus, Boyer, Dubois, Pelletan, and Lallement. Sabatier and Deschamps have already been referred to in speaking of French surgeons in tiie latter part of the eighteenth century. Pierre Lassus (1741-1807), pi'ofessor of surgery in the £cole de Sant6 and consulting surgeon of Napoleon I., was a learned surgeon who was the author of a good history of anatomy, of a manual of operative surgerv (2 vols., Paris, 1794), and of Pathologic clururf/ica/e (2 vols., Paris," 1805-0(3). Alexis Boyer (1757-1 833) was a pupil of Desault and surgeon of the Charite, a modest, quiet, studious, hard-working man, without much originality or brilliancy either in his clinical work or his lectures and writings, but a careful compiler and a thoroughly reliable teacher. His Traite den iiudarJien chirun/icalcs (11 vols., l.S14-2(j) is a practical svs- tem of surgerv, the must complete of its kind then in existence, and for many years it remained the highest authority in this branch of medical literature. His chief contributions to practical surgery were his descrip- tions of the painful crepitation of tendons, of translucency of the tumor as diagnostic in hydrocele, of bleeding fungous tumors, and of the com- plications of fissure of the anus. His system is ciiaracterized by Mal- gaigne as a sununary of the works and opinions of the French Academv of Surgery, which is no doubt correct. It is a resume of French sur- gery which he gives, and he has little or nothing to say of the surgery of Germany, of England, or of America. Antoine Dubois (1756-1837), a pupil of Desault, professor of anat- omy in the ftcole de Sante, was a skilful surgeon and a good clinical teacher, but wrote nothing of imj)ortance. Philippe Jean Pelletan (1747-1829), a pupil of Louis and of Sabatier, succeeded Des;udt as chief surgeon at the Hotel Dieu, became professor of clinical surgery at the founding of the Medical Faculty of Paris, and consulting surgeon to the emperor. In 1815 he was professor of o])era- tive surgerv, and retired from ])ractice in 1823. He was an eloquent lecturer, but made no valuable contributions to the art. His C Unique chirurr/irafe ('■'> vols.) was pul>lislied in 1810-11. Andre Marie Lallement (1750-1830), a pupil of Desault, was surgeon to the Salpetriere anil professor of surgery in the Medical Faculty. He wrote only a few papers for periodicals. To these should be added the names of Larrey, Percy, Dufouart, and Siuicerotte. 10() THE HISTORY AND LITERATURE OF SURGERY. Dominique Jean Larrey (17(50-1842), the most distinguishod military surgeon at the end of tiio last an< fJe cliirtiiyie (Paris, 1821). Pierre Francois Percy (1754—1825) was professor in the military medical school in 1820. At his suggestion a battalion of litter-bearers, or a hospital corps, was created in the Italian war. To the second period (1814-;}5) belong Dupuytren, Richerand, Roux, Marjolin, Lisfranc, Sanson, and Jules (_'lo(|uet. erat(U- or teacher, but he had nothing of the impartial spirit of the true critic, and the man whom he praised one year he would denounce the next. He made no special contributions to surgery with the exception of a case of resection of the fifth and sixth ril)s on the left side, being the first instance in which such an ojieration had been performeil to this extent. Philibert Joseph Koux (1780-1854) was a student and warm i)ersonal friend of Bichat, \\hom he succeeded as a teacher. He became surgeon at the Charite in 1810, professor of surgery in the faculty in 1820, and succeeded Dupuytren at the Hotel Dieu in 1835. He first became cele- THE inSTOEV AND LITERATURE OF SURGERY. 107 brated by the publication, in 1815, of his Bekttion d'nn voyage fait a Londres oi I8I4.; ou parall^le de la chinuyic aiKjloinc arcc la chirurc/ie franqoise — a book which had considerable influence in dilfusing in each country a knowledge of what had been done in the other, in spite of the crude and superficial views on many points which it presented. His most important contributions to the art were in plastic surgery, partic- idarlv in staphylorrhaphy, which he first performed in 181!l, and in suture of the ruj)tured perineimi, which he first performed in 1832. He gave the first distinct course of lectures on surgical anatomy in 1812. His most important literary work was his Quarante annecs de pratique chirurgicale, of which but two volumes were published, the first, relating to plastic surgery, appearing in 1854, and the second, on diseases of the arteries, in 1855. Jeau Nicolas Marjolin (1780-1850) was prosector of anatomy in 1800, and in 1816 became second surgeon of the Hotel Dieu, but soon retired to avoid unpleasant association with Dupuytren. In 1819 he became professor of surgical pathology. He was a good surgeon and extremely popular as a teacher, but was not distinguished as an operator. His name remains connected with the form of malignant degeneration of chronic ulcer of tlie leg known as the " Marty ulcer of Marjolin." Jacques Lisfranc (1790-1847) studied at Lyons and Paris and gradu- ated iu 1813, after which he served for a short time in the army and then settled in Paris. In 1825 he became second surgeon at La Pitie, and a short time afterward, on the death of B^clard, he became the chief surgeon at this hospital. He sought to reduce ojicrative surgery to mathenuitical rules, and his name is connected with methods of par- tial amjjutation of the foot, of amputation at the wrist, the shoulder-joint, and the hi]), and with methods of resection of the head of the humerus, for removal of the lower jaw, for excision of the rectum, and for ampu- tation of the neck of tlie uterus. He was an excellent operator and clinical teacher, liut envious of the greater success of some of his contem- poraries, particularly Dupuytren and Velpeau, and died dissatisfied with himself and witii every one around him. His principal publications are — Clinique chirurgicale de I'hopital de la Fitie (3 vols. 8vo, Paris, 1841-43) and Precis de raedecine op^raioire (3 vols. 8vo, Paris, 1845—48). Louis Joseph Sanson (1790-1841) was a pupil and friend of Dupuy- tren. After serving in the army from 1812 to 1.S15, he returned to Paris, and in 1825 became the second surgeon of the Hotel Dieu. In 1836 he succeeded Dupuytren as professor of clinical surgery, winning the place by concours. The first forty years of his life were a continued struggle with ])overty, and his subordination to Dujniytren prevented him from obtaining tlie re|)utation to which his skill as a diagnostician and operator entitled him. His jjrincipal work was the Nourraux elements de patho- logic medieo-chirurgicalc, par Roche et Sanson (4 vols., 1824 ; 3d ed. 1833), of which he wrote all the surgical part. Jules Germain Cloquet (1790-1883) came to Paris in 1810 and be- came preparer for the museum of the School of Medicine. He published a valuable scries of anatomical observations on hernia in 1817, and a magnificent work on human anatomy, containing a large number of plates, Mhich is still classic; in 1831 he l)ecamc ])rofessor of surgical jiathoiogy, and succeeded Dubois in the chair of clinical surgery iu 1833, which lOS THE HISTOKY AND LITERATURE OF SURGERY. position he retained until ISTjO. He eontrihutcd a larjije number of papers on anatomical and surgical subjects to the journals, and devised a number of new instruments. Joseph Souberbielle (1754-1846) studied at Paris under Desault and entered the army. He took his degree in 1813, after \v]ii<']i he remained in Paris, devoting himself chiefly to litiiotomy, and especially to the supraj)ubic method. He was a relative of Frere Come and of his nephew Baseilhac, and inherited their instruments and reputation. He is said to have performed the suprapubic operation over twelve hundred times. To this period l)elongs the introduction of lithotritv, with mIucIi are especially connected the names of Civiale, Leroy (d'lLtiollcs), and Hcur- teloup. Jean Civiale (1792-1867) studied at Paris, graduating in 1820, and made a specialty of the diseases of the urinary organs, and especially of lithotrity, which he successfully performed on a living human subject in January, 1824. In 1828 a special section for those afflicted with calculus was set apart for him in the Hospital Necker, and his practice became enormous. He had much mechanical ingenuity and dexterity, but he was neither a speaker nor a writer, and the greater part of the numerous publications which appeared under his name were really written by Jourdan, Boisseau, Begin, and others. In his first book, Xouirlles con- siderations SUV la retention (F urine, etc. (1823, p. 115), he referred to a report of Pouteau that " haricots blancs " had passed from the stomach into the urinary bladder, etc., and said : " Si les faits rapportes sont exacts, ccs corps suivent-ils le torrent de la circulation?" Some kind friend pointed out the blunder to him before the edition was put on the market, and he cancelled the greater part, but a few had been sent out as pres- entation copies, and these are now regarded as curiosities in medical literature. Jean Jacques Joseph Leroy (d'fitiolles) (1798-1860) studied at Paris, graduating in 1824, prior to which he had devised a three-pronged instrument for seizing and perforating a stone in the bladder, and his whole life was mainly devoted to this branch of surgery and to bitter contests as to priority of invention. He was not, however, a pure specialist, and was a much more scientific man than Civiale. The list of his publications is a long one, but they are comparatively brief papers. Charles Louis Stanislaus Heurteloup (1793-1864), son of Baron Nicolas Heurteloup, a distinguished French army surgeon, studied in Paris, graduating in 1823, and almost inniiediatcly turned liis attention to the suliject of lithotripsy and to criticism of the work of Civiale and Leroy (d'Etiolles). He greatly improved the instruments used in lith- otripsy, and is said to have spent one hundred and fifty thousand francs in perfecting his inventions. From 1828 to 1832 he was in London, and published there hh Principles of Lifliofriti/ {18SI). To this period also belong Delpecli and Lallemand of INIontpellier. Jacques Mathieu Delpech (1777-1832), a native of Toulouse, gradu- ated at :Montpellier in 1801, after which he studied in Paris. In 1812 he obtained, by concours, the chair of surgery at Montpellier, and soon became celebrated as an operator and as a clinical teacher. In the height THE HISTORY AND LITERATURE OF SURGERY. ]09 of liis fame he was assassinated by a patient wlioni lie liad treated for some disease of tlie genitals. His principal contributions to snrgery relate to hospital gangrene and to ortiiopivdia. He tirst j)i)inted out that tubercular disease of the vertebrte was the frequent origin of Pott's dis- ease of the spine, insisted on the importance of the tilirous tissues in con- nection with deformities, and in 181(3 performed subcutaneous section of the tcndo Achillis with the avowed intention of thus excluding the air and obtaining union by tirst intention. The successor of IX'lpech in the chair of clinical surgery was Michel Serre (1799-1849), who gradu- ated at ^Nlontpellier in 1825, and who published his Trniie de la reunion immediate, etc., in 1830, and his Traite sur Part de re.staurcr les difform- ifes de la face, etc., in 1842. Claude Fraufois Lallemand (1790-1853), a native of Metz, studied at the jNIilitary Medical School of that j)lace, and at the age of thirteen entered the army medical service. In 1811 he went to Paris and became an assistant to Dupuytren ; in 1819 he was appointed professor of clinical surgery at Montpellier ; and after the death of Delpech he was the chief surgeon in the south of France. In 1823 he lost his jdace for ten months through clerical intrigues, but M'as repliiced by the Council of Public Instruction. He is best known as the author of T>ei< jiertes m'miiudes inrolontaires (.3 vols., 183*3-42), of which several English translatiiins were published. He devised the method of autoplasty by bending with- out twisting the flap, and the method of treating erectile tumors by the insertion of needles. In the third period (1835-47) come Gerdy, Velpeau, Blandin, A. Berard, I^augier, Jobert, Amussat, and Vidal. Pierre Nicolas Gerdy (1797-185(3) studied in Paris under the most adverse circumstances of poverty and sickness, and in 1828 became second surgeon to La Piti6, where he was under the orders of Lisfranc, who gave him very few opportunities. In 1831 the surgeons of the hospitals were placed on an ecpial footing, the position of surgeon-in- chief being abolished. In 1833, as the result of an intrigue of r)u])uv- tren to suppress Velpeau, Gerdy became professor of the princij)k's of surgery in the faculty, and in 1839 was appointed surgeon to La Charite, taking the place of Guerbois. The list of Gerdy's works is a long one, but he was a physiologist rather than a surgeon, and his most important surgical publication was his Traite de.^ bandages et de.H ^Jonseinoit.t (2 vols., 1837-39). Alfred Armand Louis Marie Velpeau (1795-18(37), the son of a blacksmith, whose trade he learued, studied at Tours, ^\•here he received the diploma of officier de sante, and in 1820 came to Paris, and soon became assistant preparer for Cloquet. He graduated in 1823, and pub- lished his Traite d'anatomie chirurgicule, the first complete and syste- matic work in which the details of regional anatoniv were throughout considered with reference to tlieir surgical relations. In 1828 he Ijecame surgeon to the Hosj)ital St. Antoine, and in 1830 to La Pitie, where ho remained until 1834, when he was elected to the chair of clinical sur- gery in the faculty left vacant by the death of Boycr. In 1832 he ])ub- lished his Noiircaux elements de medecine oprndoire (3 vols, and atlas), the largest and most complete work on this subject which liad vet appeared. The English translation of this by Townsend, with notes 110 THE HISTORY AND LITERATURE OF SURGERY. of Valentine Mott (New York, 1847), and especially the latest edition, with additions by G. C. Blackman (New York, ISofi, 3 vols, and atlas), is a ^reat storehouse of liistorical data relating- to the prineipal Oj)ei-a- tions of surgery up to that date. In 18o4 he pul)lishcd his Traitf dcx maladies du .sehi, a large hook, eharai'terized by Trelat as the most orig- inal, personal, and probably the most durable of his works, and whicli must not be confounded with his Petit traite des maladies du sein, pub- lished in 1838 as a reprint of his article in the Dictionnaire de medecinr, and which was translated into English by Parkman in 1840. He made no great discoveries or improvements, yet he contril)uted grcatlv to the progress of surgery Ix'tween 1825 and 1855, and especially in surgical anatomy, the pathology of pysemia, the diagnosis of tumors, and the diseases of the breast. A man of strong common sense, an indefatigable M'orker, a conscientious and conservative critic, an excellent teacher and operator, his lessons were followed by crowds of pupils, including mam- \\'h() became distinguished surgeons in other countries as well as in France. Philipp Frederic Blandin (1798-1849) graduated at Paris in 1824, in 1828 became a surgeon to the Hosj)ital Bcaujon under Marjolin, and in 1841 succeeded Richerand in the chair of ojierative surgery. He also became surgeon to the Hotel Dicu. Blandin was not a great surgeon nor a great teacher, and there is little in his writings which is of interest at the present day, but he was a sensible, practical, honest man who did good Avork in iiis time. Augusta Berard (1802-46) studied at Paris, graduating in 1829, became a surgeon of the Central Bureau by eoncours in 1831, and, sul)- sequently, surgeon to the hosjiitals St. Antoine, Salpetriere, Nccker, and La Pitie, and in 1842 succeeded Sanson as professor of clinical surgery in the faculty. The student part of his life was one of great poverty, shared by his brother, P. Berard, who devoted himself to physiology. A. Berard wrote some excellent eoncours theses, many articles in the Dictionnaire de medecine, and began, with Denonvilliers, a Compendium dc chirur8 — 11 ), which was a popular manual and reached a fifth edition in 1860. He invented serres-tines, was the first to inject a solution of nitrate (if silver into the uterine cavity, and conti'ibuted largely to our knowledge of syphilis, successfully opposing Ricord, the great authority of the day, in some important points relating to this disease. Joseph (tcusouI (1797-1858) studied at Ijvous and Paris, graduating in 1824, and in 1826 became chief surgeon of the Hotel Dieu of Lyons, where he soon accjuired celebrity as a bold and skilful operator. He first (in 1826) excised the entire upper jaw, in 1827 he removed the parotid gland, and, first in France, excised half of the lower jaw, and he first treated varices with caustic. He M'rote very little, his chief publication being hia Lcffre chiriirf/icale sitr (pwltpies iii(dadicii r/ravcs du sinus ma.v- illaire et de I'os ma.riUaire inferieiir (1833). Amedce Bonnet (1802-58) studied at Paris, where he graduated in 1832, and in 1833 obtained the position of surgeon to the Hotel Dieu at Lj'ons by concours, after which he Ijccame a professor in the school, and was soon celebrated as a teac-her. His principal publications are — Traite des sections tendine.uses et mnscidaircs dans la strabisme, la mjinpie, etc. (1841), Traite des maladies des articidations (2 vols., 1845), and Traite de therapentiqne dcs mrdadies a rticidcdrcs (1853), which latter remain as valualile contributions to the surgery of the joints. Charles Gabriel Pravaz (1791-1853) studied at Paris, graduated in 1824, and devoted himself to ortho]);rdic surgery, associating himself with Jules Guerin in a private orthupicdic hospital. In 1835 he settled in Lyons. His principal contribiuions to surgery relate to orthopiedia 112 THE HISTORY AND LITERATURE OF SURGERY. — which he was one of the first to ])lace on a scientific fonndation — to the use of percliloride of iron, to tiie use of fine liollow needles for the injection of varices or erectile tumors, etc. Raoul Henri Joseph Scontettin (1799-1871), a native of Lille, entei'ed the army, and i!;raduated at Paris in 1822. He liecame one of the most distiniiiiisiied of Freneli military surgeons, was professor in the school at Metz in 18;i(i, and in 184U held the same position in the mili- tary hospital at Strasburg. In 1854 he was in charge of the military liosjiital in Constantinople and Pera, after which he returned to Metz, and was in charge of the military hospital until his death. He was a voluminous writer on matters connected with military medicine and surgery, and an excellent operator. He successfully performed traciie- otomy on liis infant daughter six weeks old. Jean Baptiste Lucien Baudens (1804-57) studied in Paris, entered the army medical service in 1823, and graduated in 1829. He served in Africa from 18.'50 to 1837, in 1838 became professor in the hospital at Lille, and in 1842 professor at Val de Grace. He M'as a distin- guished military officer, and made numerous contriljutions to military surgery, among which may be mentioned his ttuuque des pluies d'armes fl feu (1836) and his La guerre de Crimee, les campements, les abris, les mnbulances, les hopitaux, etc., first published in the Revue des deux- moiides in 1857, and in separate form in 1858. Jean Gaspard ]?laise Goyrand {lS()3-6(j) studied at Paris, graduated in 1828, and, returning to his native city Aix, became chief surgeon to the hospital, and one of the most distinguished of the French provincial surgeons of his day. He made important contributions to the literature of am])utations, fractures of the hnver end of the radius, operations for h)ose l)odies in the joints, extirpation of the tongue, urethral fistula, etc. His principal work is his ('Unique cldruryicule ; viemoires et obser- vations de ehirurgie, etc: (Paris, 1870), published after his death by Dr. Silbert. Jules Roux (1807-77), a native of Aix, studied at Toulon, entered the naval medical service in 1828, and became professor in the school of Toulon in 1842. He was distinguished as an operator and clinical teacher, devised a useful modification for disarticulation of the foot, made improvements in the ojteration of trephining, and was the first to make use of iodine injections in disease of the shoulder-joint. He made numerous contributions to the journals and learned societies, but jiwb- lished no important separate M'ork. To the fourth period (from 1847 to the present time) belong, in addi- tion to those already referred to and those who are still li\'ing and do not yet belong to history, a nundjer of well-known surgeons, of whom the most prominent at Paris were Malgaigne, Nelaton, Denonvilliers, Chassaignac, Richet, Follin, Broca, Dolbeau, Gosselin, and Tr^lat. Joseph Fraufois Malgaigne (1806-65), a native of the Vosges, son of an officier de sante, studied at l^u'is, graduating in 1831, and after a short term of military service in Poland settled in Paris, where he became a surgeon of the Central Bureau in 1835, and began to teach surgical anatomy. He was successively surgeon to the Hospital St. Louis and to La Charite, and in 1850 won by concours the chair of operative sur- gery vacated by Blandin. THE HISTORY AND LITERATURE OF SURGERY. 113 Malgaigne was the greatest surgical historian and critic which the worUl has yet seen, a brilliant speaker and writer, whose native genins, joined to incessant labor, brought about a new mode of judging of the merits of surgical procedures — the mode of statistical comj)arison joined to experiment. He was not a great operator, and although he made some improvement in the art, such as his hooks for the treatment of fractures of the patella, his suggestion of suprathyroid laryngotomy, etc., these are of small importance as compared with his work of explod- ing errors, exposing fallacies in reasoning, and bringing to bear upon tlie work of the present day the light of tlie experience of the past, of which his treatise on fractures and dislocations affords many excellent examples. The reports of his spci'clics in the Bulletins of the Academy of ^Medicine are among the most delightful reading in surgical literature. Auguste Nelaton (1807-73), the son of a French soldier, a native of Paris, studied at the Hotel Dieu under Du])uytren and at the Found- ling Hospital, graduating in 1836. He became professor of clinical surgery in 1851, was for many years a colleague of Malgaigne at the Hospital St. Louis, and for' the last fifteen years of his life was the most popular surgeon in Paris. He was, in fact, in many respects, the best sur- geon whom France has produced during the century, being unsurpassed as a diagnostician, as an ojierator, and as a clinical teacher, and was a modest, quiet gentleman who attacked no one and befriended many. He made mnnv improvements in surgical tccluiiquc, among which was tlie porcelain-headed prol^e wliich he devised for demonstrating the presence of the bullet in Garibaldi's ankle-joint. He brought into French prac- tice the principle, so strongly insisted on by Guthrie, of ligating both ends of a wounded artery within the ^v()und for either primary or secondarv hemorrhage, improved tlie methods of treatment of naso- jiharvngeal tumors, first clearly demonstrated retro-uterine hsematocele, and brought ovariotomy into good repute in France. He wrote com- paratively little, his chief publication being his Elements cle pafhologie chirurcjicale (5 vols., 1844—59, of which the last two volumes were pub- lished by A. Jamain). The only publication of his clinical lectures is that made in 1855 by Dr. ^y. F. Atlee of Philan he held until his death ; and Francesco Rizzoli (1809-80), professor of surgery and obstetrics in Bologna in 1840, who was distin- guished as an operator and teacher. The scheme of medical studies adopted in Austria in 1810 prescribed a five years' course in medicine or the higher surgery, and a two years' course tVn- country doctors. In 1822 tiie course at the Military Medieo- chirurgical Academy, or Josephinum, was extended to five years, and this college had the right to grant degrees. In 1849 much more power was given to the professors in the various universities as to the arrange- ment of studies, but a complete separation between the faculties and the medical associations was not made until 1873. In 1872 separate diplo- mas for surgery were abolished. In Prussia a system of medical study was arranged in 1825. It pro- vided for physicians who studied at the universities, and for what were called surgeons of the first and second class. The surgeons of the second class were surgeons' apprentices who served for a short time in a military hospital or attended a few lectures at a medico-chirurgical college ; their examination was a very easy one, but demanded some knowledge of anatomy, and they were mostly comparatively uneducated men of an inferior class. The surgeons of the first class had to study at a university or a medico-chirurgical school for three years, and were not required to know Latin, as were the physicians, showing that sur- gery was still considered inferior to medicine. In 1852 it ^^•as ordered that there should be but one class of doctors, but the obtaining a med- ical degree did not give the right to ]tractise. At present the education and the standing of physicians and of surgeons are the same throughout the empire. During the first fourteen years of the nineteenth century the Xapo- leonic wars produced an urgent demand for army surgeons, esjiecially in Austria, which was often the field of conflict. Vienna had the leading surgical schools in Germany at that time, founded by Leber in connec- tion with the university, and In- Braml)illa in connection with the Mili- tary Medical School, and the princijial surgeons in Southern Germany after Leber were von Kern, Rudtorffer, ^^'attmann, and Zang. Vincenz Sebastian von Kern (1760-1829), professor of surgery at Laibach in 1797, became professor of practical and clinical surgery in the Vienna University in 1805, and exercised a powerful influence on 118 THE HISTORY AND LITERATURE OF SURGERY. tile (lovclopnicnt of siirjierv iiiiil suru'ical teachini; in (u'niiany and Xorthurn Italy nntil his resif^nation in 1824. He groatly .simplified the prevailing treatment of wounds, returning to the water-dressings of Magatus and I'ejecting plasters and salves, and was a skilful operator and an exeellent teacher. Franz Xav. Riidtorffcr (1 TfiO-ls;].')) commenced teaching in tlic great Vienna Hospital in ISO], .nid in ISIO succeeded Ijel)cr as ])rofessi)r of surgery, which position lie lield until he retired in 18121. Joseph von Wattniann (177!)-18(j(i), son of a surgeon and })upil of von Kern, became ])rofessor at Laibach in 1816, at Innsbruck in 1818, and at Vienna in 1S24, retiring in 1848. He was a celebrated operator, and gained great re])utation as a teacher. Cliristoph B. Zang (1 772-1 S."]")) graduated at Vienna, entered the Austrian army, and in 18U6 became professor of surgery in the Josephi- num. He published Darstclhtng hlutiger hcilkunstleri.^eher Operationen (4to, 181.3-21) — an excellent manual of operative surgery, which reached a third edition and was translated into Italian. In North Germany the principal surgeons of this period were Mnrsinna, Rust, C. J. M. Langenl)eck, v. Walther, Hesselbach, and Briinninghausen. Christian Ludwig Mursinna (1744-1823), a barbei-'s apprentice, en- tered the Prussian army in 1701 under Theden. In 1787 he became sur- geon-genei'al, and professor of surgery in the military medical school at Berlin, which jiosition, in connection with that of surgeon to the C'harite, he retained after his retirement from military service in 1809. He was a skilful operator and a good administratoi", who greatly im- proved the medical service in the Prussian army, but wrote little except occasional addresses and papers for journals. Joh. Xeponudv Rust (1775-1840) studied in Vienna and Prague, and became professor of surgery at Cracow in 1803. From 1810 to 18ir) he was one of the surgeons of the General Hospital in A'ienna, and in 1816 he succeeded Mursinna in the army medical school at Berlin, becoming professor in the University of Berlin in 1824. Conrad Joh. M. Langenbeck (1776-1851) studied at Jena, Vienna, and Wiirzburg, and in 1802 settled in Gottingen, where he soon began to teach anatomy and surgery. In 1.S14 he became professor of anatomy and surgery and surgeon-general of tiie Hanoverian army. In 1802 he published a treatise on litliotomy ; in 1806 the first volume of his Biblio- thck fiir die Chii-urgie, of which the eighth and last volume appeared in 1828 ; and in 1822 the first volume of his Nono/or/ic inif, Busch, Linhart, Wagner, and Baum. Bernard Kudolph Konrad von Langenbeck (1810-87), the most dis- tinguished German surgeon of the nineteenth century, took his doctor's degree at Gottingen in 1835, became ])rofessor of surgery at Kiel in 1842, and succeeded I)ictl'cnl)ach in the chair of surgery at Berlin in 1847. In conjunction with his pupils, Billroth and Gurlt, he established the Arohiv fur klinische Chirurgie in 1861, a journal which has con- tained the most important contributions tt) surgery made by German surgeons since that date, and he was the founder of the Dcidschc Gescll- schuft fur Chirurgic in 1872.

His operations and improvements of the teehnieal methods of surgical o|)erations are too numerous to mention. Some of tiie most im])ortant of tiiem relate to plastic surgery of tlie nose and of tlie liard palate, and to o})eration8 for tumors at the base of the cranium, for removal of tiie tongue, etc. His greatest con- tril)ution to surgery, however, has been his pupils, among whom may be numbered nearly every prominent surgeon in Germany of the present day. Georg Friedrich Louis Stromeyer (1804-7(1), son of Chr. Fr. Stro- meyer, surgeon to the king of Hannover, studied at Hannover, Gottin- gen, and Berlin, and graduated in 182G. In 1829 he Ix'gan to teach in the surgical school at Hannover, in 1838 succ'ceded Jaeger as pro- fessor of surgery at Erlangen, in 1842 accepted the same chair in Frei- burg, and in 1847 succeeded Jjangenbeck at Kiel. He became surgeon- general of the Schleswig-Holstein army, serving in the war of 1849, and surgeon-general of the Hannoverian army in 1854, serving in tlie war of 18(i(J. His chief contributions to the art were connected with orthoptedic surgery and tenotomy, and especially with resections in military surgery. He performed subcutaneous section of the tendo Achillis in 1831, being the first after Delpech to do so. His ])rinci])al pul)lications were Beit rage znr ojicrdfircu Orlhojiadik (1838), Jldiidhiich lis Acatleniy in Vienna, re-estalilished for the purpose of training medical officers for tiie Austrian army. His name is best known in connection with the Handbuch der aUgemeineu %md speciellen Chirurgic, edited by Billroth and himself (1865-82). He was a skilful diagnostician and operator and a cultured and polished gentleman. Franz Schuh (1804-65) studied in Vienna, graduating in 1831, became surgeon to the General Hospital in A'ienna in 1837, and pro- fessor of surgery in 1842. He was an excellent practical teacher and writer, aided much in increasing the reputation of the school, and con- THE HISTORY ASD LITERATURE OF SUR(JERY. 123 tributed niinuTous papers to tlie journals.

Gustav Biedermann Giinther (1801-66) studied at Ijeipzig, graduat- ing in 1824, and in the following year became an assistant to Frioke in the General Hospital at Hamburg. In 1831 he was appointed professor of surgery in Kiel, and in 1841 accepted the same position at Leipzig. He was a good anatomist and a careful, jjainstaking teacher, but was not distinguished as an operator. His principal work is his Lvhre von den blutigen Opendionen uin menseh/irhen Korper (4to, 1859-65). Albrecht Theodor Middeldorpf (1824-68) studied at Breslau and Berlin, graduating in 1846, and in 1856 became professor of surgery at Breslau. He introduced the use of the galvano-cautery, made improve- ments in the treatment of fractures and of gastric fistula, and was one of the best clinical teachers of his time. His principal publications are — Beiirdge .sar Lehre von den Knochcnbriiohen (1853), Die Galvano- caustik (1854), Ueberblick iiber die Akidopeiradik (1856), and Co)n- mentatio de fiatulin nentriculi externis, etc. (1859). Carl David Wilhelm Busch (1826-81), son of the cclclirated obstet- rician Dietrich Willi. Heinr. Busch, studied in Bei-lin, graduating in 1848, and after extensive travels became an assistant in Langenbeck's clinic in 1851. In 1854 he accepted a call to Bonn as professor of clinical surgery, and remained there until his death. He was a volu- minous writer and made valuable contributions to the literature of gun- shot wounds, fractures and dishjcations, diseases of the joints, plastic sur- gery, and hernia, the majority ajipearing in periodicals and transactions. His Lehrbueh der Chirurgie (2 vols., 1857-69) was his princij)al work. Wenzel von Ijinhart (1821-77), the son of a surgeon, studied in Vienna, graduating in 1844 ; became an assistant of Dumreicher, and in 1856 accepted a call to Wiirzburg as professor of clinical surgery. He was a skilled anatomist and ojicrator and an excellent teacher.

Carl Ernst Albrecht Wagner (1827-70), son of a celebrated physi- cian, studied in Berlin, graduating in 1848; became an assistant in Langenbeck's clinic, surgeon to tiie hospital in Dantzig in 1853, and in 1858 professor of surgery in Kiinigsberg, where he acquired great re])u- tation as a teacher. Wilhelm Bauni (1799-1883) studied at Konigsberg and Berlin, 124 titt: msroRY and literature of surgery. graduatino- in 1822; contiiiiu'd liis studies in Vienna, Ijdiidon, and Pariy ; iu I80O became surgeon in charge of the municipal liospitid at Dantzig ; in 1842 accepted the position of professor of surgery at Greifswald ; and in 1849 tooiv the same chair at GiJttingen, from wliich he retired in 1867. He was a learned man and a good teacliw', but published nothing. To this period also belong Zeis, Stilling, and Heine. Edward Zeis (1807-68), a native of Dresden, studied at Leipzig, Bonn, and Munich, graduating at Leipzig in 1832, after which he settled in Dresden. From 1844 to 1850 he was professor of surgery at Marburg, at the end of which ])eriod he returned to Dresden and i)ecame surgeon to the city hospital. His principal publications are — HdmUmck (ler plastischcii Chtrutr/ie (1838) and Die Literatur unci Geschichte der plastlachcn Chirurgie (1863-64). Benedict Stilling (1810-79) studied at Marburg, graduating in 1833, and became assistant in the surgical clinic. Soon after he settled in Cassel, where he remained for the rest of his life. He is much better known as a physiologist and investigator of the nervous system than lie is as a surgeon, but he M^as the first ovariotomist in Germany, and Ix'tween 1856 and 1870 published several papers on stricture and on internal urethrotomy. Jacob von Heine (1800-79), of a liimily of instrument-makers and orthopaedists, student at Wiirzbui-g, graduated in 1827, and established an orthopaedic hospital in Cannstatt which became celebrated. His principal publications are — Bcob(ichti(iif/en iihcr Ldhvmiir/sziwtdiHje der untcru Extremitdten und deren BchamUung (1840), Ueber spontane und congenitale Luxationen, etc. (1842), and Spinale Kinderldhmung (1860).

Between 1850 and the present time the leading surgeons of Ger- many, besides those already mentioned, and those who, being yet living, do not come within the scope of this paper, were LoetHcr, AA'ilms, Simon, Thaden, Lijcke, Hueter, Maas, Leisrink, Vogt, Volkmann, and Billroth. THE HISTORY AXD LITERATURE OF SURGERY. 125 Gottfried Friedricli Franz Loefflor (1815-74) studied at tlie Fried- rich A\'illu'lin Institut in Bei'lin, and became one of the most distin- guished of the German army surgeons. His principal works are — Lirundsatze unci Regeln fur die Behandlmig der tichusswunden im Kr'iege (1859) and Das preussische Militar Sanitdtswesen und seine Reform (1868-<50). Robert Ferdinand Wihiis (1824-80) studied at Berlin, graduating in 1846, and in 1848 became an assistant of Eartels in the Bethanien Hospital, of which he was placed in charge in 1862. He M^as one of the leading surgeons in Berlin, and was popular as a teacher, but wrote little beyond the rejiorts of his hospital. Johann Dumreichcr (1815-80) graduated at Vienna in 1838, became assistant to ^Yattraann, and took charge of .one of the surgical clinics in 1849. He wrote very little. Christoph Jac. Fried. Ludw. Gustav Simon (1824-76) studied at Giessen and Heidelberg, graduating in 1848, and at once entered the Hessian army, in which he became medical director in 1861, in the same year was appointed to the chair of surgery at Rostock, and in 1867 accepted a call to the same position in Heidellierg. His first jiublication was Ucber Schussumuden, etc. (1851), soon after which, on a visit to Paris, he became accpiainted with Jobert's method of operating for vesico-vaginal fistula, and on his return established a small hos|)ital, acquired great reputation as an operator for such affections, and published a number of pajiers on the surgery of the female genitals. After going to Heidelberg he performed the first operation for nephrectomy in 1869, and published his C'hirurf/ie der Nieren in 1871, the second part appear- ing after his death, in 1876. He was a bold and skilful surgeon, and made numerous improvements in methods of investigating and treating surgical affections. He Avas also a voluminous writer, but his publica- tions were concise monographs, and not large, systematic treatises. Adolf Georg Jacob von Tliaden, a native of Holstein, studied in Heidellierg and Kiel, graduating in 185.'!, after which he was for two years an assistant of Esmarch, and in 1861 became surgeon of the new city hospital at Altona. He was a skilful, scientific surgeon. George Albert Liicke (1827-94), a native of Magdeburg, studied at Heidellierg, Halle, and Gottingen. He became assistant to Blasius at Halle in 1854, and soon after became assistant to von Langenbeck in Berlin, and jirivatdocent. In 1865 he became professor of surgery at Berne, and in 1872 accepted the same position at Strasburg, where he remained until his death. Carl Hueter (1838-82), son of a well-known obstetrician of Mar- burg, graduated in 1859, after which he studied in Vienna, I^ondon, and Paris, and became a privatdocent in Berlin and an assistant of Langen- beck. In 1868 he succeeded Simon as professor of surgcrv at Rostock, and in 1869 accepted a call to the same chair at Greifswald. Hueter was a scientific surgeon, giving great attention to pathology and bacteri- ology ; he was also a skilful operator, made many improvements in method in resections, tracheotomy, excision of the rectum, etc., and \vas a voluminous writer. His jirincipal works are — Klinik der Gelenk- krankheiten (^1870-71 ; 2d ed. 1876-78), Die ulhjeiimite Chirurgie (1873), and (Trundriss der Chirurgie (1880-82). 12() THE HISTORY AXf) LITKHATVRE OF SVRGEBY.

Franz Lcisrink (1845-85) studiiMl in Gottingen and Kiel, graduating in 18()8, and settled in Hamburg, where lie beeanie distinguisheil as a surgeon and I'ontribnted some valuable papers to perioilieals. His most important work was Die inodcnie Radikal- Opcmtion der Uiitcrkilmbruche, einc statistlsche Arbeit (1885). Paul Fried. Immanuel Vogt (1849-85) studied at Greifswald, grad- uating in 1865, and in 1882 succeeded Hueter as professor of surgery. PI is principal works M'cre — TJie ehirurgixchcn Krcaiklicitcn der oberen Ed'treiiiiti'iten (1881) and Mittheilungen aus der Chirurc/ischen Klinik in Greifm-ald (1884). Eichard von Volkmann (1830-89), son of Alfred Wilhelm Volk- mann, professor of anatomy and physiology in the University of Halle, was educated at Halle, Giessen, and Berlin, and obtained his medical degree in 1854. He was an assistant in the surgical clinic of Professor Blasius, in 1857 became privatdocent, and in 18(j7 ])rofessor of surgery at Halle. With Langenlx'ck and Simon he founded the German Sur- gical Association, and in 1874 s;iid before this society: "There is no such thing as luck in surgery : for every case of pyaemia, erysipelas, and necrosis after amputation the surgeon who treats it nuist be hclil respon- sible." His contributions to surgery and to surgical literature were numerous and important, and he was the first German carefully to study Lister's methods and to ui-ge their adoi>tion upon German surgeons. Volkmann was a poet as well as a surgeon, but issued his poems under another name, and few persons know that Richard Leander, the German poet, is the same person as Richard Volkmann, the famous surgeon of Halle. Theodor Billroth (1829-94), a native of Bergen on the island of Riigen, studied at Greifswald, Gottingen, and Berlin, graduating at the latter university in 1852. He became assistant to von Langeubeek, privatdocent in 1856, professor of clinical surgery at Zurich in 1860, and ])rofessor of surgery in the University of Vienna in 1867, succeed- ing Franz Schuh. During the last twenty-five years he has lieen one of the most celebrated surgeons in the world as an investigator in sui'gi- eal pathology, a bold and successful operator, a voluminous writer, and a clinical teacher. He first excised the larynx for cancer in 1873, first successfully excised a large portion of the stomach in 1881, and gave a strong impetus to the progress of operative surgery of the intestinal tract. His lectiu'cs on surgical pathology and therapeutics have passed through many editions and translations; his reports on clinical surgery were translated into English in 1881, and the total number of his pub- lished books and papers was about one hundred and forty. The history of surgery in Denmark is merely the old story of the barbers and barber surgeons until near the end of the eighteenth century. The T^niversity of Copenhagen was founded in 1479, and possessed a nominal medical faculty consisting of two or three physicians who read the works of Galen and Avicenna. In 1559 some attempt was made to introduce anatomical studies, and the young physicians had to travel in THE HISTORY AND LITER ATUBE OF SURGERr. 127 foreign countries before completing their studies and ohtaining their degree. In 1577, Frederick II. issued statutes for the Collegium Chi- rurgicum of Copenhagen, in which it was ordered, seeing that fnmi ancient time there had been only si.x barbers in the city — i. e. barber surgeons — tiiat tlie term of apprenticeshij) should be three years, and tlien the apprentice was to travel in foreign countries for fiiur consecutive years. Ti-avclling lithotomists had to olitain the a])pnival of tiie cor- poration bcf ire thev were allowed to operate. Controversies between the pliysicians and the barbers occurred as a matter of course. In 17-'!(i, Simon Krueger (1687-1760), a barber surgeon, with others, founded tlie "Theatrum Anatomieo-chirurgicum," a school for teaching anatomy and surgery, which ]>rospered for the next twenty-four years, but was sup- pressed in 1772. In 17S.3 the Academia Chirurgica was created. Krueger was an excellent teacher, but wrote very little. Heinrich von Moinichen, a surgeon of Copenhagen, published in 1665 his Observatioiies Jlledico-chirurgica', of which there were three later editions. Georg Heuermann (1722-GS), professor of medicine in the Uni- versity of Copenhagen, pulilished in 1754-57 his Abhandlunr/ dcr rornfhinxfcn cliiriirf/i.iclicn Ojicrdtioiien am ■menschUchen Korjjer, a well- arranged and illustrated work. Alexander K. Koelpin (1731-1801) graduated in 1763, after which he studied under Hunter in Ijondon and Le C-at in Kouen, and returned to Copenhagen and became chief surgeon of the Friedrichs Hospital in 1766. In 1785 he became professor of the newly-organized surgical academy. Henry Callisen (1740-1824), a native of Holstein and a pupil of Simon Krueger, passed his preliminary examination in 1767, after which he studied at Paris and under William Hunter in London. Returning to Copenhagen, he became chief surgeon of marines, and took his degree as doctor in 1772, and in 1773 succeeded Burger as professor of surgery. His Inntitufloncs cJiirurf/icir hodlcrnw (1777) and his Si/stcma cliinir(/lie hodierna', etc. (1778) passed through several editions and translations, and were popular text-books until the beginning of the nineteenth century. Adolf Carl Peter Callisen (1787-1866), a nephew of Henry Callisen, graduated at Kiel in 1809, and became a professor in the Surgical Academy in Copenhagen in 1817. In 1842 he was professor of sur- gery in the university. His best-known work is his Medici iiIucIk's SchriftsfeUer-Lc.vicon der jvtzt kbend.cn Acvzte, etc. (in 33 vols. 8vo, 1830-45). ■ The iirst distinguished surgeon in Sweden was Olaf Acrel (1717-1 806), who was chief surgeon of the Sera])him Hosjiital in Stockholm after its foundation in 1752. ' He becanic jirolessor of surgery in 1755, and his teachings had great influence in the development of surgery in Sweden. His princii)al work is Kirnrgiskn Hnndelner (Stockholm, 1759), which was translated into Dutch in 1771, and into German in 1772 and 1777. Peter af Bjerkin (1755-1818), a pupil of John Hunter and a sur- geon in the Finnish army, became chief surgeon of Stockholm in 1809. He was the greatest Swedish surgeon in the early part of this century, but wrote nothing of importance. t^ 128 Till-: HISTORY AND LITERATURE OF SURGERY. The first professoi' of .surgery and obstetrics at the University of Christiania was Magnus Andreas Tiudstrup (17(39-1844), a native of Copenhagen, who entered the Norwegian military niedieal service, became sui'geon-gcneral, and in 1814 professor. He wrote very little. Jacob Christian Johan HenriU (Jundelach ]Moeller (1797-1845), a native of Jutland, studied in Copenhagen, and in 1842 became professor of surgery, and was a distinguished clinical teacher. Joh. August Liborius (1802-187U), a surgeon of Gothenburg, was well known in his day as a skilled practitioner, and wrote on the starched bandage, on hemorrhoids, and on herniotomy. The leading surgeon of Sweden in recent years was Carl Gustav Santesson (1819-8()), a native of Gothenburg, who graduated at Upsala in 184(j, and became ])rofessor of surgery in the ytockholm school in 1849, retiring in LSS."). He contributed a number of papers to the journals, and published Ojii hoftlcdcn och ledbrosken iifi anatomiskt por])at, in 1840, he was appointed ])rofcssor of surgery in the Medico-chirurgical Academy of St. Petersburg. His attempts to improve the sanitar}- condition of the military hospital connected \vith the academy created much ill-feel- ing, and for a time he was considered and treated as insane. During the Crimean War he was active at Sevastopol, and incurred ill-^\•ill by his deHunciation of the abuses connected with the Russian military administration during the siege, the rcsidt of which was that he was compelled to resign his professorship in the academy at St. Petersburg. His contributions to surgery ^\•ere numerous in relation to gunshot THE HISTORY AND LITERATURE OF SURGERY. 129 wounds, amputations, and the surgery of bones, and his name is con- nected with a method of ostcophistic amputation through the foot devised by him in 1854. The list of his publications is a long one, the most important being his Rcchcrohes prutlques ct physioloffiques sur F etherisa- tion (1847); I'cqijjort medical d'Kii voyage au Caueasr, contenant fa statiftfiqiie compuraiiee des ainputatioiiit, etc. (1849) ; Anatome fopne/rapliica^ •sectionibus per corpus huinaiium conyelatxim , etc. (fob, 1852-59) ; Chirur- ffische Anatomie der Arterien-staemvie und Fascien (1861); and Grund- ziiffe der allgemeinen Kriegsclnrnrgie (1864). Little is known of the Russian surgeons who wrote only in Russian, for veiy few of their worlds have been considered worth translating. Ivan Rklizky (1805-61), professor of clinical surgery at St. Peters- burg, in 1847 jniblished a treatise on operative sui'gery in Russian, of which there were two later editions. Peter Dubovizki (1815-67), professor of surgery at Kasan, in 1837 published a treatise on hemorrhage, and one on litliotinpsy in 1838. Sablozky-Desjatovski (1816-82), professor of surgery at the Medical Academy of St. Petersburg in 1842, wrote on hernia, diseases of the testicle, and venereal diseases. Polycarp Girsztowt (1827-77) studied in St. Petersburg, was an army surgeon in the Crimea in 1853-56, and became professor of surgery in Warsaw in 1860. He contributed to periodical literature, but wrote no special work of any importance. Hippolyt Korzeniowski (1827-79) studied at St. Petersburg, became professor of surgery in Warsaw in 1868, and professor of surgery in St. Petersburg in 1871. Karl Daniel von Haartman (1792-1877) was professor of surgery and obstetrics in the University of Hclsingfors from its foundatiou in 1833. He published Casus chirurgici in 1815. One of the most distinguished and best known of modern Russian surgeons was Julius Szymanowsky (1829-68), a native of Riga, who studied at Dorpat, graduating in 1856. In 1858 he went to Helsingfors as assistant professor of surgery, and in 1861 accepted a call to Kicw, where he acquired a great reputation. He was a skilful operator and an excellent teacher. His principal publications are Der Gypsverband init besonderer Beriicksichfiguug der Militiirchirurgie (1857) and a treatise on operative surgery in Russian (1864-65), of which the first part was translated into German and published in 1872. Carl Reyher (1846-90), a native of Riga, studied at Dorpat, gradu- ating in 1871, became an assistant of von Bergmanu, and privatdoccnt, entered the Russian army medical service, and became a distinguished surgeon and teacher in St. Petersl)ui-g. His principal pulilications relate to antiseptic methods, diseases of the joints, laryngotomy, and gunshot wounds. Upon the establishment of the Spanish rule in Mexico the medical system of Spain was estal)Iished with it, including the barbers and the barljcr surgeons. The first provision for the examination of physicians and surgeons appears to have been made in 1646, being a l)oard com- jxised of three persons, two of whom were physicians connected with the university. From this date to 1700 it is reported that forty-seven physicians, one surgeon, three apothecaries, and eighteen barbers were Vol. I.— 9 130 THE HISTOJRY AND LITEBATUEE OF SURGERY. examined and .iiitlioiized to ])ractise.

Tii 1742 it was ordered that no surgeon siiould inidertake to ])raetise niedieine iKir to give [)nrgatives or emetics or diaphoretics or other drugs, and tiuit no apotiiecary siiduid put up prescriptions of a surgeon for sucli drugs. In short, it is the old story of an attempt by the physicians to suppress the surgeons. In 1719 it Mas ordered that in the examination of the surgeons no one should be approvef this century whose name is now best known to fame was Dr. Ephraim McDowell (1771-1830), a native of A^irginia, who studied in IOdinl)urgh in 179.'! under John Bell, who was then giving special attention to diseases of the ovaries. In 1795 he commenced practice at Danville, Kentucky, and soon became the lead- ing pliysician of the West. In 1809 he performed the first methodical excision of the ovary fin* the cure of tumor of that organ, and published an account of it, and of two other similar cases, in the Eelcetie Repertory of Philadelphia in 1817. His reports of the operation attracted little attention at the time, and the few pul)lished comments on them were mostly expressions of doul)t as to the accuracy of his statements ; but the paper of Mr. Lizars, " Observations on the extirpation of the ova- ria," in the Edlnhtirf/h Mrdiral (mil Siuyieal Journal in 1824, made them generally known, and altiiough it was long after that date before ova- riotomy became recognized as a jn-oper surgical operation, yet the credit due to McDowell for originating it has never since been seriously dis- puted. He wrote very little and very reluctantly, and was not a teacher 134 THE HISTORY AND LITEIiATURE OF SURGERY. in any sciiool, but his luinic stands hioh in tlie list of the great surgeons of America. Another distinguislied surgeon of tliis period was Dr. Nathan Smith (1 7(32-1 829), a native of Massaehusetts, wlio studied in the Harvard Medi- eal Seiiool, in Edinlturgii, and in Li)ii(h)n, and in 171)7 founded a medical sciiodl in connection witli Dartmouth Cullege. In 181.3 he l)ecame pro- fessor of medicine and surgery in Yale College. He was tlie second person to perform ovariotomy in this country, which ho did in July, 1821, without any knowledge of the work of McDowell. He performed the first amputatiim at the knee-joint in the United States in 1824, first used the trejihine in loealizeil inflammation and al)seess of the shafts of the long bones, and introduced the manipulation method in the treatment of dislocations of the hip-joint. He wrote little, but an account of his methods and practice is given in a little book entitled 2IaJical and sur- gical memoirs, edited by his son, Nathan R. Smith (published at Balti- more in 1831). It contains an excellent paper on necrosis, a description of an improved apparatus for the treatment of fractures of the femur, remarks on dislocations of the hip, etc. Some bold operations were performed in these early days Vjy men who wrote nothing and of whom little is known ; for example, abdom- inal section for extra-uterine pregnancy in 1759 by John Bard of New York, and in 1791 by William Baynham ; the ligation of the common carotid in 1803 by Mason Fitch Cogswell, and in 1807 by Dr. Amos Twitchell of New Hampshire ; the complete excision of the clavicle in LSll by Dr. Charles McCreary of Kentucky ; and the excision of a part of the lower jaw by Dr. Wm. H. Deadrick of Tennessee in 1810. In 1819, Dr. Wm. C Daniel of Savannah first employed extension by means of a weight in the treatment of fracture of the femur, but did not pul)lish the method until 1.S29 (Am. J. Med. Sc, 1829, iv. 330). In 1823, McGill of Maryland successfully ligated both carotids; in 1824, Dr. D. L. Rodgcrs removed nearly the whole of both upper jaws. Between 1820 and 1850 the prominent surgeons in the large cities were John C. Warren and George Hayward in Boston ; Valentine Mott, J. Kearny Rodgers, Willard Parker, Alfred C. Post, and John Watson in New Y'ork ; W. Gibson (above referred to), J. R. Barton, George IMcClellan, George W. Norris, and Thomas D. flutter in Phila- delphia ; Nathan R. Smith in Baltimore; R. D. Mussey in Cincinnati; and Daniel Brainard in Chicago. Valentine Mott (1785-1865), a native of Long Island, the son of a physician, studied medicine at Columliia College, obtaining his degree in 1806. He then A\'ent to London, became a pupil of Astley Cooper, returned in 1810, and was appointed ])rofessor of surgery in Columbia College, and in 1813, when this school was merged in the faculty oi' the College of Physicians and Surgeons, he retained the chair of surgery. In 1826, with the other professors of the College of Physicians and Surgeons, he resigned his chair, and then M'ith several of his associates founded the Rutgers ]\Iedical College ; he took the chair of operative surgery in the College of Physicians and Surgeons, which he resigned in 1834 on account of his health. In 1840 he was appointed to the jirofessorship of surgery in the Medical Department of the University of New Y'ork. For the next ten years his reputation drew crowds of students from all THE HISTORY AND LITERATURE OF SURGERY. 135 parts of the United States. In 1850 he resigned the chair, making anotlier visit to Europe. In the spring of 1852 he was appointed emeritus professor of surgery in tiie IMedical Department of the Uni- versity of the City of New York, and from that time until liis death he delivered an annual course of lectures. ]\Iott's first contribution to operative surgery was the ligature of the iiHiominate artery in 1818, the patient surviving for a long time, but finally dying of secondary hemorrhage. The case established the prac- ticability, and the propriety in certain cases, of the operation. It was finally successfully performed by Dr. A. W. Smythe of New Orleans in 1864, in which case repeated hemorrhages also occurred, and the verte- bral arteiy was ligated fifty-four days after the first operation. Mott first applied a ligature to the primitive iliac in 1827; in 1828 he entirely removed the clavicle for osteosarcoma; in 1812 he made an original operation for the relief of ankylosis of the lower jaw. At the time when, in 1821, he excised the right half of the lower jaw in a case of tumor he was not aware that a similar oiieration had been jierformed in 1810 bv Dr. W. H. Deadrick of Tennessee, since no history of the operation was published until 1828. Dupuytren in 1812 had removed a large part of the lower jaw for cancer. Amputation of the hip-joint was performed by Dr. Mott in 1824, and it was for some time supposed that it was the first operation of the kind in America, but it is now known that it was ]ierformed by Dr. Walter Brashear of Kentucky in 180(3, but no aeeount of liis case had ever l)een publislied. Speaking of his excision of tiie clavicle, Dr. Mott called it his " ^\'aterlo(^ opera- tion," since it was performed on the 17th of June, the day before the anniversai-y of that battle. In 1813, Dr. Charles McCreaiy had removed the right clavicle for disease of the bone, but it was little enlarged, com- paratively isolated, and the operation was a very simple one, being entirely different from the extremely difficult operation performed ])y Dr. Mott. The patient rapidly recovered. Besides the innominate artery, he tied the subclavian eight times, the primitive carotid fifty-one times, the carotid twice, the common iliac once, the external iliac six times, the internal iliac twice, the femoral fifty-seven times, and the jiopliteal ten times. His writings consist mainly of reports of cases and operations for periodicals. J. Kearny Kodgers (1793-1851), a native of New York, was a pupil of Dr. Wright Post and graduated at the College of Physicians and Surgeons in 1816. He studied in London under Astley Cooper, became surgeon of the New Yt)rk Hospital in 1822, and tied the left subclavian artery within the scaleni for aneurism in 1845, the first time this opera- tion had l)een perfiirmed : it was unsuccessful. The first successful operation of this kind was by Dr. Halsted of Baltimore in 1892. Dr. Kodgers successfully wired an ununited fracture of the humerus in 1827 after excision had been unsuccessfully performed, perhaps the first ope- ration of this kind, and made a cuneiform osteotomy in ankylosis of the hip in 1840. He wrote only a few pajiers for periodicals. Willard Parker (1800-84), a native of New Hampshire, studied under John C. Warren, and graduated at Harvard in 1X30. He was for a short time professor of surgery in Berkshire Medical College, and was a colleague of Gross in Cincinnati. In 1839 he became professor 136 THE HISTORY ASD LITERATURE OF SURGERY. of siivficiy in tlic College of Ph\>iciiuis and Surgeons, surgeon of Bellevue Hospital in 1845, and surgeon of the New York Hospital in 1856. He was an excellent teacher and operator and greatly beloved by his pupils, M'ho constituted his best contributions to surgery. He was the first operator for strabismus in this country. Alfred C. Post (l«(.)5-85), a native of New YorU'and a nepliew of J)y. \\ right Post, graduated in medicine at the (.'ollege of Physicians and Surgeons in New York in 1827, and continued his studies in Paris, Berlin, and Edinburgh. He was one of the founders of the Medical Department of the University of the City of New York in 1851, in which he was professor of surgery and pathological anatomy. He wrote no systematic treatise, but contributed numerous cases to the journals, and was sjiecially skilled in plastic surgery. John Watson (1807-63), a native of Ireland, came with liis pa- rents to America in 1810, and graduated in 1832. He became sur- geon of the New York Hospital in 1838, where he first introduced regular clinical instruction in surgery, though Dr. Alexander H. Stevens had previously delivered occasional clinical lectures. He contributed many cases to journals, but wrote no systematic treatises. He collected what was at that time the most valuable private medical library in this country, the greater part of ^vhich, after his death, ^\•as left to the New York Hos])ital Library. John lihca Bai-ton (1794-1871), a native of Lancaster, Pa., grad- uated at the Univei-sity of Pennsylvania in 181.S, and became surgeon of the Pennsylvania Hospital. His name is asst)ciated with a form of fracture of the lower end of the radius, with a special form of bandage for fraetin-e of the jaw, and with osteotomy for ankylosis, which he first performed in 1826. In 1834 he wired a fractured patella. George McClellan (1796-1847) M-as a native of Connecticut and a pupil of Dr. Dorsev, graduating at ttie University of Pennsylvania in 1819. He founded the Jeti'erson ^Medical College in 1824, in which he was professor of surgery until 1838. He excised the body of the lower jaw in 1823, excised the parotid gland for tumors, and was a bold and showy operator. After his death liis Ixiok on Principles and practice of surr/crj/ was published in 1848 : it is note«'orthy only for the very excellent description of shock which it contains. George Washington Norris (1808-75) was a native of Philadelphia, and graduated at the University of Pennsylvania in 1830. After two years' service in the Pennsylvania Hospital he went to Paris, and stud- ied under Dupuytren, A^eljjeau, and Roux. He became surgeon to the Pennsylvania Hospital and professor of clinical surgery in the Uni- versity of Pennsylvania. His name is well known in medical literature from the extremely valuable statistical contributions to practical surgery which he published in the American Journal of the Medical Sciences be- tween 1828 and 1854. They rank among the best work of this kind which has ever been done in any country, and his results are quoted in all subse(]uent treatises ujion the subjects upon which he wrote. Thomas Dent Miitter (1811-59),'a native of Virginia, graduated at the L'f^niversity of Pennsylvania, after which he studied medicine in Paris. He became professor of medicine in the Jefferson INIedical Col- lege in 1841, and is celebrated for his plastic operations for the cure of THE HISTORY AXD LITERATURE OF SURGERY. 137 deformities resulting from burns. He gave liis nuiscum to the College of Physicians of Pliila(leli)hia, with thirty thousand dollars for its main- teuauce and the endowment of a leeturesliip. In this connection may be mentioned : William E. Horner (1793-1853), a native of Virginia, who became a surgeon in the hospital department of the army in 1813, when he was twentv vears old and before he had graduated. He iiecame professor of anatomy in the University of Pennsylvania in 1831, succeeding Dr. Borscy. His name is connected with the Wistar and Horner Museum, which he bequeathed to the university, and also with tlie muscle \\hieh lie named the " tensor tarsi." His contributions to surgery are to be found in papers in the American Journal of the 3ferlieal tSciences. R. D. Mussey (17SO-1806), a native of New Hampshire, studied medicine under Dr. Nathan Smith, and graduated at the University of Pennsvlvania in 1809. He was professor of the theory and practice of medicine at Dartmouth, 1814; professor of anatomy and surgery in the .same school, 1819 ; professor of surgery in the ]\Iedieal College of Ohio at Cincinnati in 1838 ; and professor of surgery in tlie Miami Medical College in Cincinnati in 1852. He was a bold operator, and first tied both carotid arteries in 1S27 for a large bleeding tumor of the head, and removed the scapula and clavit'lc for tumor following amputation at the shoulder-joint. His only contributions to surgical literature were in the shape of re})orts of cases in the journals. Daniel Brainard (1812-()R), a native of Western New York, graduated at the Jeifcrson ^Medical College, Piiiladcliihia, in 1834. He successfully amputated at the hip-joint in Chicago in 183.S, which established his reputation, and in 1.S54 ])iiblished an excellent essay on the treatment of ununited fractures. He was the founder of Rush jMedieal College. One of the most celebrated surgeons of the West of this period was Benjamin W. Dudley (1785-1870), a native of Virginia, who graduated at the University of Pennsylvania in 1806, after wliich he studied in Paris and Jjoudon, returning to Lexington in 1814, and became pro- fessor of anatomy and surgery in the Medical Department of the Transylvania University in 1817. His reputation rested mainly upon his operations for lithotomy, which he performed two hundred and tM'enty-five times with almost unparalleled success. He wrote nothing except a few short essays, the first of which. Observations on injuriei< of the head [ineluecame professor of anatomy, and then of surgery. He was surgeon to the Bellevue and New York Hospitals and to the Roosevelt Hospital, and in the latter j)art of his life was the leading surgeon in New York City. He was the first to operate in peritonitis due to perforation of the appendix. Here also may be mentioned J. Marion Sims (1813-83), a native of South Carolina, who connnenced practice in Montgomery, Alabama, and there devised his mode of operating for vesico-vaginal fistula; he came to New York in 1853, and became the founder of modern gyna'cology. The Philadelphia surgeons of this period who have finished their work are Gross (father and son), Agnew, Pancoast, and Smith. Samuel D. Gross (1805-84), a native of Pennsylvania and a grad- uate of the .Jeiferstm Medical College in 1828, after tilling various chairs in Western schools and in New York accepted the chair of surgery in the Jefferson INIedical School in 1865, from which he retired in 1882. He was a man of strong personality and great influence, an incessant worker, a voluminous writer, an excellent teacher, and one of tlie most distinguished surgeons of his time. He wrote the first .systematic treatise on pathological anatomy by an American author, made original experiments on wounds of the intestines, published 140 THE HISTORY AND LITERATURE OF SURGERY. valuahle monographs on diseases of the bladder (1851; 2d ed. 1855), on foreign bodies in the air-])assages (1854), and a system of surgery in two hirge vokimes (1859 ; (Jth ed. 1882), wliieli is an imjiortaut book of reference. His son, Samuel W. Gross (1837-89), graduated at the Jefferson IVIedieal College in 1857. (Jn the oiitlircak of tjie Civil War he beeanie a surgeon of volunteers, acting as medical director in various depart- ments until 18()5. In 1882, on the retirement of his father, he was elected one of the professors of surgery in Jefferson Medical College. Pie made numerous contributions to surgical literature in the journals, published a treatise on Tumors of the manuiiary glands in 1882, a treatise on Impotence and sterility in 18X1, and assisted his father in the j)re])aration of the various editions of his System of Surgery. He was a bold yet careful operator and an earnest and eloc|uent lecturer. Joseph Pancoast (1805-82), a native of New Jersey, gradu;ited at the University of Pennsylvania in 1828. He began teaching ])ractical anatomy and surgery in 1881. In 18.j8 he was elected professor of .surgery in the Jefferson Medical College ; in 1847, professor of anatomy in the same college. He published his Trrntine on operative surgery in 1844 (3d ed. 1852). He was distinguished for his operations in plastic surgery, especially for exstro|)hy of the bladder ; devised the operation of section of the tliird branch of the fifth pair of nerves at its issue from the base of the skull, and of the second branch of the fifth pair at the same place ; was a skilled anatomist, a dexterous 0])e- rator, and a popular clinical teacher. Henry H. Smith (1815-90), a native of Philadelphia, graduated at the University of Pennsylvania in 1837, after which he studied in London and Paris. He became professor of surgery in the Uni\'ersity of Pennsylvania in 1855, and resigned in 1871. His Si/sfcm of opera- tive siirgeri/, published in 1853 (2d ed. in 1856), contains a valuable history of surgery in the United States, with an index of the princij)al contributions of American writers on subjects connected wuth operative surgery down to the year 1854. Francis Fontaine Maury (1840-79), a native of Kentucky, grad- uated at Jefferson Medical College in 18G2; jierformed the first opera- tion of gastrotomy in this country, excision of the brachial plexus for painful neuroma, operation for exstrophy of the bladder, and two opera- tions for extirpation of the thyroid gland. He was surgeon of the Philadelphia Hospital. Dr. I). Hayes Agnew (1818-92), a native of Pennsylvania, grad- uated at the University of Pennsylvania in 1838. In 1852 he became the head of the Philadelphia School of Anatomy, to which he soon added a school of operative surgcrj' ; in 1863 he left this to become demonstrator of anatomy in the University of Pennsylvania, in which he became professor of clinical surgery in 1878 and professor of surgery in 1871. A highly-skilled anatomist, an unusually dexterous o])erator, and a keen, shrewd diagnostician, he acquired an immense ])ractical experience in all forms of siu-gical affections and treatment, which he embodied in his treatise on the Principles and practice of .mrgcri/, pub- lished in three large volumes in 1878-83, and again in a second edition in 1889. He was one of the few great surgeons who have continued to THE HISTORY ASD LITERATURE OF SURGERY. 141 practise medicine as well as surgery until the end of their career, and he did tliis liecause he believed it made him a better surgeon. J. L. Atleo (1799-1885), a native of Lancaster, Pa., graduated at the University of Pennsylvania in 1820, and practised at Lancaster through- out liis life. In 1843 he revived the operation of ovariotomy, and with his In-other established it on a firm basis. He was the first successfully to remove both ovaries at one operation. Washington L. Atlec, his Iirotlier (1808-78), was a pupil of George McClellan, and performed liis first operations for ovariotomy in 1844. Tiiis operation he performed three hundred and eighty-seven times, and had more influence in popularizing it than any other man in this country. His most imjKirtant contribution to literature is on the diagnosis of ovarian tumors, ])ublished in 1873. He was also celebrated as an ope- rator for the removal of uterine tumors. Jonathan Knight (1789-18()4) studied at the University of Pennsyl- vania, and became professor of anatomy and physiology in the Medical Institution of Yale College when it was organized in 1813. In 1838 he became professor of surgery, and held the chair to the end of his life. Paul F. Eve (1806-77), a native of Georgia, graduated from the University of Pemisylvania in 1828. He studied several years in Europe, was a volunteer surgeon in the Polish Rebellion of 1831, and became professor of surgery in the Medical College of Georgia in 1832, in Louisville University in 1849, in the Nashville University in 1850, in the Missouri INIedical College of St. Louis in 1868, and professor of operative and clinical surgery in the University of Nashville from 1870 to the date of his death. He published ^4 collvcHon of rcmarbihlc w.sc.s- in tiurr/eri/ (Philadelj)hia, 1857) — a most useful and interesting work, and it is highly desirable that a similar collection should be made for the lat- ter half of this century. George C. Blackman (1819-71), a native of Connecticut, graduated in medicine at the College of Physicians and Surgeons, New York, in 1840, and for the next ten or fifteen years was engaged in study in Great Britain and in France, and as surgeon of an Atlantic packet-ship ; in 1855 he liecame professor of surgery in the jNIedieal College t)f Ohio. He was a skilful diagnostician and anatomist, a bold surgeon, an excellent clinical teacher, and thoroughly at home in surgical literature. He contril)uted largely to periodicals, re-edited Mott's edition of Velpeau, and translated the work of Vieneath and licliind the heart, and which had remained there over two months. His contributions to the literature of surgery are found entirely in periodicals. Robei't Nelson (1794-1873), a native of Canada, became distinguished as a surgeon in Montreal, and especially as a lithotomist ; implicated in tlie rebellion of 1837, he came to the United States, for a short time filled the chair of anatomy and surgery at Castleton, A^t., and Pittsfield, Mass. ; went to California in 1849, and finally settled in New York. He is the author of a pamplilet, Gastrotoiiii/ for the removal of non-malig- nant tumors from the abdominal cavity (New York, 1864), and of jiapers in the journals, especially in the Northern Lancet, of which he was the editor 'from 1850 to LSbo. John T. Hodgen (1824-82), a native of Illinois, professor of anatomy in the Missouri Medical College in 1852, and professor of clinical and military surgery in 1872, made valuable contributions to methods of treatment of fractures, and his splint is well known. George Alexander Otis (1830-81) was a native of Boston, and gradu- ated in medicine at the University of Pennsylvania in 1851. He studied in Paris, entered the army in 1861, was curator of the Army ]\Iedical Museum, and wrote the first two surgical volumes of the Medical and surgical history of the war of the rebellion, using the vast material in a thoroughly scientitic manner. Moses Gunn (1822-87), a native of New York, of Scotch descent, settled at Ann ^Vrlior, Mich., became jirofessor of anatomy and surgery in 1850, and ])rofessor of surgery in Rush ^Medical College in 1867, succeeding Brainard. He was a skilled anatomist, a ])opular teacher, and wrote a valuable paper on reduction of dislocations liy manipulation. John M. Carnochan (1817-87), a native of Savannah, (ia., a pupil of Valentine Mott, a surgeon in New York City, was a daring ojx'rator. He excised the entire lower jaw in 1851 and in 1864, removed IMeckel's ganglion and the superior maxillary nerve in 1856, and ligated the fem- oral for elephantiasis in 1851. Besides journal articles he was the author of A treatise on .... congenital dislocations of the head of the femur (New York, 1850, 8vo) and Contributions to opercdive surgery and sur- gical jxdhology (New York, 1877-83, 4to). Robert Alexander Kinloch (1826-91), a native of Charleston, gradu- ated in medicine from the University of Pcmisylvania in 1848, after which lie studied in London, Paris, and Edinburgh. During the Civil War he was medical director on the staffs of Generals Lee, Pemberton, and Beauregard. In 1867 he became professor of materia niediea and therapeutics in the Medical College of the State of South C'arolina, and soon afterward jirofessor of surgery, which position he held to the time of his death. He was the most prominent surgeon in his State, and Avas the first in this country successfully to excise the knee-joint for chronic disease and to treat fracture of the lower jaw by wiring the fragments. He was also the first surgeon to open the abdomen in cases of gunshot wounds in which there is no protrusion of the viscera. His contributions to surgical literature were entirely to medical periodicals. THE HISTORY AND LITERATURE OF SURGERY. 143 Other surgeons well known in their own States were George Hayward (1791-lSG.S), professor of surgery in the Harvard Medieal School, who published some valuable surgical reports in journals and in a volume in 1865; Jacob Randolph (1796-1848), surgeon of the Pennsylvania Hospital, who introduced lithotrity in America ; Horace A. Ackley (1812-59), professor of surgery at Cleveland, Ohio, 1843-56 ; Ely Ged- dings (1799-1878), professor of surgery in Charleston, S. C, the outlines of whose lectures were published in 1858; John Neill (1819-80), pro- fessor of surgery in the Philadelphia College; Ernst Krackowizer (1821-75), a native of Upper Austria, who came to New York in 1850, and was surgeon of the Brooklyn City Hospital ; Julius F. Miner (1823-86), professor of surgery in Buffalo ; Joseph C. Hutchinson (1827-87), professor of surgery in Brooklyn ; and Josiah C. Nott (1804-73), professor of surgery at Mobile, but better known as a writer on ethnology. The history of surgery in the United States has been told by Gross (Am. Jour. 3'led. Sc, N.'S., Ixxi. 1876, 431), and its triumphs in the way of first operations have been set forth by Dr. Dennis {3Icdical Record of New York, 1892, xlii. 637-648), and to these papers the reader is referred for details \\liich there is not space here to give. In addition to anajsthesia, ovariotomy, and the foundation of modern gyntccology, American surgeons have contributed much to the art in the way of perfecting apparatus for the treatment of fractures by extension ; of reduction of (lisloeations by manipidation ; of the treatment of dis- eases of the liip and spine ; of tlie ligation of large blood-vessels ; of the removal of tumors ; of the surgery of the brain, spinal cord, mouth, jaws, kidney, liver, and urinary organs. It is true tliat the scattered, um-eported "first cases" of some of the great operations by early American physicians must be considered as entitling the individual to praise for his boldness or ingenuity rather than as "contributions to surgery," because it is not until such procedures have been made known to the profession and become a part of surgical literature or teaching that they have become useful ; but from the beginning of the history of the art we find that the majority of the " first operations " of all kinds have been made, not by distinguished professors and famous authors, but by men who were neither teachers nor authors, and the names of many of whom are unknown to this day. This is true of amputations, lithotomy, herniotomy, trephining, excision of the breast, ligation of a wounded artery, C;esarean section, hysterectomy, ovari- otomy, and of the invention of many of the primitive forms of some of the most important instruments of the present day. " Les petits pro- phets," as Verneuil styles them, are worthy of all honor, and one of the objects of a history of surgery is to keep their names at least from being forgotten. American surgeons have contributed at least a fair share to tlie common stock of knowledge in the past, and it seems prob- able that they will do still more in the near future. They have been, for the most part, " practical men :" it is only within the last twenty years tiiat the scientific problems of surgical pathology have been the subject of experiment and study in this country, but it is quite prob- al)]e that the John Hunter or Josej)h Lister of America is now busy Avith his preliminary work. 144 THE HISTORY AND LITERATURE OF SURGERY. A most imi>ortaiit stc']> in the })rogress of medicme was made when physicians and surgeons began to form associations and societies for the purpose of mutual improvement and for the piil)lication of papers read befiire them, rather tiian for guariHng trade interests; and the trans- actions of such societies form a most vakiable section of medical litera- ture. The first of these societies Avhich was devoted specially to sur- gery, and whose jiublications were im])ortant, was the Academic royale de chirurgie, the memoirs of which appeared in o quarto volumes (Paris, 174.3-74, and again in 15 vols. 12mo, Paris, 1771-87, in 5 vols. 8vo, Paris, LS19, and in 3 vols. 8vo, Paris, 18.38). The MemoireH and Bulletins of the Societe de Chirurgie de Paris, j)ublished from 1847 to the present time, and forming -52 volumes; the VerhcnuUunr/cn of the Deutsche Gcsellschaft fiir Chirurgie, in 35 vol- umes, 1872-93 ; tlie TranKoetions of the American Surgical Association, in 10 volumes, 188.3-92; and the Proccs-nrboiix, mcmoirefi, etc. of the Oingres fraacais de Cliirurgie, — are the most important of the purely sui'gical publications of this class in the present century. No surgical association ])ublishing professional reports has existed in Great Britain, the Royal Colleges of Surgeons of Edinbui-gh, of England, and in Ire- land not having undei'taken this line of work. The following is a list of the most imjioi-tant journals devoted especially to general surgery, arranged in order of date : Chirnrr/ischc Bihliotliek, von August Gottlieb Richter, 1771-96, 8vo, Gtittingen u.

Inflammation is one of the most inij)oi-t;iiit subjects in medicine and surgery, and one of the most difficult to comprehend. It ha.s played an important part in the history of medicine, and most of the theories of disease formerly held were more or less based on conceptions of its nature. It is only in comparatively recent years, when patient observation and experiment have taken the place of theory, that the true nature of inflammation has been better understood. ^\'ere we to take up all the phenomena of inflammation and stud}' each process fully, it would ^practically include all pathology. So exten- ■sive is the subject, and so intimately is it related to other pathological processes, that it has recently been proposed to abolish the term " inflam- mation" entirely, and to consider the various jilienomena under other divisions of pathology where they naturally belong. The phenomena of inflammation are closely connected with the i)athology of the circula- tion, with the degeneration and regeneration of tissue, with the action of bacteria, with injuries, etc. Still, it is well to have some one term to include the tissue-changes following an injury, and we may define inflam- mation as the sum of the phenomena which take place in the tissue as the effect of an injury. The object of these various jihenomena is to over- come or to diminish the eifects of the injury. The study of inflammatory processes may be well begun with the changes which take place in the blood-vessels, and in the connective tissue, which everywhere stands in close connection with these. It will be well to consider the character of the normal coimective tissue and the relations which it has \\ith the circulation. The con- nective tissue in the body serves the important function of binding together the various parts, and acts as a support to the blood-vessels, which, with this tissue, grow into the various structures in the course of development. The connective tissue varies in its structure. It is composed of cells and of fibres which differ in their physical and chem- ical (lualities. In places the filn-es are loosely connected together, as in the areolar tissues, and in places they are compacted in close bundles, as in the tendon. The number of blood-vessels in this tissue varies greatly in the different parts of the body, the number standing in exact relation to the importance of the adjacent epithelial structures. Most of the blood-vessels in the connective tissue do not serve the purpose of its Vol. I. — 10 ]45 146 SURGICAL PA TlKiLOG Y. nutrition, (lie tissue simply serving as a bed for their support. Where the blood-vessels in the connective tissue are for the nutrition of this alone, they are not found in such large luunbers. The nutrition of the tissue is carried on by means of tlie lymph -which passes through the walls of the vessels and circulates through the tissue. In some places there are no definite tracks taken by the lymph. In the subcutaneous areolar tissue there is a loose meshwork of fibres containing a variable number of cells, and the tissue is simply saturated M'ith the fluids. In other places, aa in the cornea, the fibres of the tissue are compacted into a dense mass containing channels and spaces in which the cells lie and in which the lymph circulates. In still other plac(^s the nutrition seems to take place through the cells alone. In the cartilage, for instance, there is a compact intercellular suljstance, with no spaces either around or be- tween the cells, so that the nutrition of this tissue is j)robably kept up from cell to cell. The vascular ])henonicna which take place in inflammation can be directly studied under the microscope in a transparent part, as in the web of the frog's foot or in the mesentery (Fig. 1). The mesentery of Fig. 1. Portion of the mesentery of a froa, showing normal circulation : a, a, small arteries just breaking up into capillaries ; o, b, small veins ; c, c, wandering cells (leucocytes in connective tissue). the frog is a thin tissue which is covered on the outside by a single layer of flat endothelial cells, beneath wliich is a layer of rather firmly-inter- woven connective-tissue fibres, with numerous blood-vessels, nerves, and lymphatics. The arteries and veins in the mesentery are relatively more numerous than the capillaries, because the tissue mainly serves to support the vessels passing from its root to the inte.stine. Under the microscope the INFLAMMA TION. 147 normal circulation can be studied and the gradual development of inflam- matory changes observed. In the various sorts of vessels ditferences in the character of the circulation may be recognized. In the arteries there is an evident pulsating stream. At each contraction of the heart the blood is swept along so rapidly tiiat it is not possible to recognize tiie individual coriniscles. In the diastole tlie stream becomes slower and we can see the individual corpuscles. In tlie veins the movement of tiie blood is a continuous one, and is slower than in the arteries. In the capillaries the movement of the blood is slow and regular. Neither in the veins nt)r in the arteries do the red blood-corpuscles completely fill the vessel. We recognize a central core composed entirely of masses of red blood-corpuscles, and between this and the wall of the vessel is a colorless zone which contains no red blood-corpuscles, and in which here and there single wiiite corpuscles roll along. In the frog's web it is necessary to injure the tissue either by chemical or mechanical violence to produce inflammation, while the mere exposure of the mesentery to the air produces sufficient injury to bring about all of the phenomena. Fig. 2. The same vascular territory as shown in Fig. 1, two hours after exposure. All of the vessels arc (lilatetl. The leucocytes aje more numerous ; they have eoUectea alonp the walls of the vessels, and in several places are passing; ihrouph : at d diapedesis of the red corpuscles is shtiwn, and at e emigration of leucocytes. Tlicre are large numbers of leucocytes in the connective tissue. If care be taken in placing the mesentery beneath the micrf)seope to pi-oduee as little injury as possible, all of tlie phenomena will take place so gradually that the single steps can be easily followed. At first no changes at all are seen in the circulation. Under some circumstances the first change seen is a contraction of the small arteries. This is always tem- 148 SURGICAL PATHOLOGY. porarv, and is often not observed, and in any case it quickly iijives ])lace to dilatation. The dilatation of" the arteries is acconijianied hy a great rapidity of circulation. The Mood tiows throut>h all of the vessels with increased speed. P^ven in the capillaries the tlow is sometimes so rajiid tliat the individual corpuscles cannot be seen. Vessels appear which were jireviously invisible from their small size. The veins take part in the dilatation, and the flow in them is also more rapid. This is the stage of active arterial hypenemia. There is more blood brought to the part by the dilated arteries ; more passes through and is carried oif by the veins. This condition of the circulation soon gives place to another (Fig. 2). The dilatation of the blood-vessels continues, but the current becomes slower. The circulation in the dilated capillaries may become so slow that they become filled with red blood-eorpuscles, and appear as red lines running through the tissue. The slowing of the current and dila- tation of the vessels are much more evident in the veins than in the capillaries, and a marked change takes place in the plasma-zone of the veins. In the normal circulation the white corpuscles are confined to this zone, and they roll along the wall in the clear fluid. These cor- puscles gradually increase in number, and the entire plasma-zone of the vein becomes filled with them. Although the blood-current of the vein is slow, the progress of the white corpuscles in the plasma-zone does not keep pace with that of the red corpuscles in the centre. They will fre- quently cling for a time to the wall of the vessel, and then again be swept away by the current. Numbers of them remain, and finally the wall of the vessel becomes lined \\ith them. These corpuscles in the j)lasma-zone undergo ra])id anueboid changes, and may move from place to place along the vessel. Some of them become apparently fixed to the wall of the vessel, and then a striking phenomenon takes place. A small bud appears on the outside of the vessel opposite the point at which a white corpuscle adheres. This projecting bud gradually becomes larger, and at the same time that part of the corpuscle inside the vessel becomes smaller, and after a variable length of time the corpuscle passes entirely through the wall of the vessel. This passage of the white cor- puscles through the walls of the vessels is spoken of as emigration, and when it once begins it goes on witli considerable rapidity, until finally the tissue outside of the blood-vessels becomes filled with these cor- puscles. They accumulate in the tissue and lie in the meshes between the fibrils and in the lymph-spaces (Figs. 3 and 4). The emigration is not always easily observed. To see it under the best circumstances vigorous frogs should be selected and care taken in spreading the mem- brane out to produce as little injury as possible. It is much more easily seen in the vessels of the bladder than in those of the mesentery. The l)ladder can be filled with salt solution, turned out through the rectum, and directly observed. Sometimes it takes more than an hour for the corpuscle to pass through the \\all of the vessel. The white corpuscles accumulate in the dilated capillaries, but to a much greater extent in the veins. Both the red and the white corpuscles pass through the walls of the capillaries. The red corpuscles may also pass through the walls of the veins, but this is comparatively rare. This passage of the red corpuscles through the walls of the vessels is called diapedesis. They pass through mFLAMMA HON. 149 Diagrammatic view of inflammatory changes in a small vein : a, normal circulation, showing plasma-zone ; b, c, d, successive changes, showing dilatation, accumulation of leucocytes, ana emigration. the walls of the capillaries in nuich ear in their most typical form in acute inflammations of the skin. If we take for example the furuncle or the infectious infiannnation which develops in the skin around the IXFLA MM A TIOX. 155 hair-follicle or glands, we find at the height of the process that the in- flamed area is retlder than the surronnding skin. It is warmer to the toneh, and if the temperature be taken with a surface tiiermometer, it may be several degrees warmer than the neighboring skin. It is swollen, appears as an elevation, and is painful. The redness is due to the greater amount t)f blood which is contained either in the vessels or, in the form of hemorrhage, in the tissues of the part. The character of the redness varies. In the early stages of the inflammation and at the periphery it is a bright red, almost approaeiiing the color of arterial blood. As the inflammation advances, and in the centre of the furuncle, it changes to the dark color of venous blood. When the blood is contained in the vessels alone, the redness may be made to disappear tjy pressure, the blood in the dilated vessels being driven out of them. Tlie redness is also due to hcmorrhagt' in the tis- sue. The areas of hemorrhage generally appear as circumscribeil spots, distinguished from the hyperajmia by the more intense color. They are easily seen in the inflamed ear of the rabbit, and are most marked where the action of the injurious agent has been most intense. By varying the dilution of the croton oil which is applied to the ear the amount of the hemorrhage in the tissue varies, and is always greatest when the less diluted oil is used. There is no tissue in the body so well adajtted to show inflammatory hypersemia and hemorrhage as the acutely in- flamed pleura. When this is stripped off and held to the light, it is of a bright-red color, a beautiful network of dilated vessels can be seen, and between these the tissue has a general diffuse redness due to injec- tion of the capillaries. Here and there in the tissue can be seen red splotches varying in size from 1 to 10 mm. in diameter, which are due to hemorrhage. More blood is brought to the inflamed part by the dilated arteries, and more flows from it. This increased passage of blood through the inflamed area takes place in spite of the slowness of the circulation in the dilated veins. In the early stages of inflamma- tion, in wliieh tliere is dilatation with increased rapidity of the circula- tion, it is evident that this must be the case, and in the later stages, in which there may be almost complete stagnation in the central portion of the area, in the periphery there is an active circulation in dilated vessels. Lawrence long ago showed that there was a greater flow of blood from an inflamed part by opening corresponding veins coming from an inflamed and from a normal part. There have been various theories advanced to account for the inflam- matory liyperiBmia. After Bernard showed the effect of cutting the sympathetic on the circulation of the rabbit's ear, the idea arose that the inflammatory hyperemia might be due to paralysis of the vaso- motor nerves. It' can be shown that this is not the case. After sec- tion of the sympathetic the hypenemia develops at once ; in inflannna- tion it comes on slowly and extends slowly. Furtlier, the hyperivmia produced by section of the sympathetic never reaches the intensity of the inflammatory hypertemia. If the ear is inflamed after section of the sympathetic, an intense hypersemia develops — more intense, as a rule, than the inflannnatory hyperreniia of the car with a normal nervous supply. Then the opposite idea was held, that the effect of the injury was to produce a spasmodic contraction of the arteries, so tiiat there 156 SURGICAL PATHOLOGY. was really a diminished supply of arterial blood to the jiart ; tlie hyper- {emia then was supposed to be due to the entry of blood into the intlanied part from surrtpundin<; ])arts by the eollateral eirculatioii. There is usually in inflammation a temporary eontraetion of the arteries, but this may be entirely absent, and it quit^kly gives place to dilataticin. The theory of stasis has also been used to account for the hyperemia. This theory was intimately connected with the humoral patholoyy and was advocated by Boerhaave. It was supposed that in inflannnation the character of the blood was altered, tiie corpuscles becoming more adhe- sive, and in consequence flowed tlu-ough the vessels with more difficulty and accumulated in the inflamed part. These views with regard to the hypersemia of inflammation have l)een given nj), and the two theories at present used to explain it are that of Cohnheim and that of Yirchow. Cohnheim explains all the vascular phenomena of inflammation by an alteration of the walls of tiie blood-vessels produced by the action on them of the agent causing the inflannnation. Virehow explains tlie congestion by an alteration in the attraction between the blood and the tissues. Cohnheim supi)Osed that the changes in the vessels were passive in character, and were due to the effect of the injury on them, and he attempted to prove this in various ways. He showed that when the blood was cut off from the vessels for varying periods, and then again turned into them, all the phenomena of inflammation could be produced, the degree depending on the length of the ansemic period. By cutting off^ the blood from them he supposed the nutrition of their walls was affected, and tlnis an injury limited to the blood-vessels was produced. He does not attempt to deflne the character of the altera- tions which the vessels undergo, and supposed that there might be either chemical or physical changes produced in them which were so delicate that they could not be detected by our metiiods of investigation, and which manifested themselves only by their effects. Almost all that we know about pathological alterations in blood-vessels relates to the various degenerations of their walls. It is certain tiiat there can be no altera- tion of the walls of the blood-vessels without affecting the tissues at the same time. The effects of the anaimia produced by shutting off the circulation from the ear will be felt by the tissues as well as by the walls of the vessels, and the inflammation which follows will be due to the injury produced in the tissue. There is nuich which is opposed to the theory of Cohnheim. The dilatiition of the vessels extends far beyond the area immediately acted on by the trauma. Sanniel has shown that if the upper portion of a rabbit's ear be inflamed Ijy ex- posing it for a few minutes to water of the temperature of 54° C, an intense congestion is produced which affects not only the vessels in the part which has been directly acted on by the heat, Init extends to the main artery of the ear. The central artery is dilated in its entire course and pulsates strongly. When tile artery is cut a considerable dis- tance below the inflamed area, more blood flows from it than from the artery of the normal ear at the same point. In the case of the cornea it is dii!lcult to assume that the action of the injury producing the inflannnation could have extended to the vessels of the sclera. It may probably be assumed for a chemical injury, but in the case where an inflammation is excited by passing a thread through the centre of the INFLAMMA TIOX. 1 57 cornea it is impossiI)le to suppose that tlie meclianieal trauma enuld have affected vessels so remote. If one hand be acutel}' inflamed, the arteries on the inflamed side are dilated and jjulsate more strongly than on the normal side. In vascular tissues the inflammatory phenomena, the dilata- tion, the emigration, etc., do not take place so far away from the injured tissue as the sclera is from the centre of the cornea. Only those vessels which are immediately concerned in the nutrition of the tissue will be affected. All the more recent work on the circulation has renioved the blood-vessels more and more from a passive role in nutrition. The increased transudation is not due to the vessels becoming simply more permeable, but is due to active changes in the vessels brought about by influences acting uj)on them. The view of Virchow that the hyper- aemia is the result of an alteration in tlie attraction l:)etween the blood and the tissues is pnjbably more nearly correct than that of Cohuheim. The blood-supply of an organ is regulated entirely by the need of the organ. An increase of function is accompanied by hypersemia. The hypei'temia is not the cause of the increased function, but it is demanded by the greater needs of a tissue for blood when its functional activity is increased. In the case of a gland more blood must be brought to the part, not only to nourish the cells in their increased activity, but to sup- ply a greater amount of material from which the specific substances secreted can be drawn. We know from the work of Heidenhain that in the ordinary jirocess of secretion the capillaries do not play a passive part, allowing indefinitely all the fluids of the blood to pass through, from which the cells may take uj) certain speciflc elements, but the cap- illaries themselves may be regarded as true secreting structures, and they allow only the substances necessary for each particular tissue to pass through them. Wiien a portion of an organ undergoes atrophy or when there is a i)ermanent loss of substance, however brought aliout, not only will tlie su]iply of blood be diminished by a reduction of the calibre of the blood-vessels brought about by coutraetion of the muscles, but it will be permanently lessened by the formation of a tissue inside of the artery which brings about a permanent diminution of its calibre. On the other hand, when a tissue calls for a greater amount of blood than can be supplied by the artery, as in the case of collateral circulation when one of a series of small arteries takes the place of a larger, the calibre of the artery will not only be increased by a relaxation of its walls, but it will be permanently increased; it will, in fact, become larger by growth. The hyperemia in inflammation is apparently called forth by the needs of the tissue for repairing, and for in other ways setting aside the consequences of the injury. The temperature of the inflamed part is increased. It is due solely to the fact that more heat is br juglit to the part by the increased afflux of arterial blood, and the rapitlity of the circulation does not allow suf- ficient time for its dissipation. When active hypersemia is produced in the rabbit's ear by section of the symjjathetic, it can easily be sho\vn by folding the ear over an ordinary thermometer that the temperature of the inflamed car is four or five degrees above that of the normal. The first exact experiments with regard to the temperature in inflamed parts were made by John Hunter. Hunter showed tiiat the fluid con- 158 SUBGICAL PATHOLOGY. tained in a hydrocele liad a temperature when it was tapped of .'53.3° C, and on the next day, after actual intlaniniation had taken ])lace, the introduction of a thermometer into the sac showed a temperature of 37.8°. He showed further that when an acute inflammation w^as produced in internal parts, as in the pleura, the peritoneum, the peri- cardium, or the deep muscles in the back and legs, the tem])eratnr(> of the inflamed part not only did not exceed, but it freipiently did not reach, the normal temjjcrature at the same place. As a result of his experiments Hunter taught that in local inflammation the tempera- ture does not exceed that of the interior of the body. The correctness of Hunter's conclusion was ojiposcd later l)y Simf)n and Weber, who found in peripheral inflaniinations produced l)y fracture of bones or by the injection of croton oil into an extremity that the temperature of the inflamed part was greater than that of the blood in the artery going to the part. This was in accord with the theory of Zimmerman which afterward appeared. It is known that a general systemic affection in which the temperature of the entire body is increased frequently accompanies a local inflammation. This is the inflammatory or traumatic fever. Zimmerman advanced t\w theory that the inflamed ])art repre- sented a local production of heat which led to increased temjierature in the entire body, the increased tem]icrature of the body being due to the heating of the blood in the inflamed part. A repetition of all of these experiments \\'ith more exact methods of measuring the temperature bv the use of the thermopyle and the galvanometer, which were carried out by Jacobson and his scholars, showed that the temperature of the rabbit's ear in the course of inflammation produced by croton oil is higher than that of the normal ear, but considerably lower than that of the rectum or vagina of the animal ; and further, that in inflamma- tion of the deep muscles of the leg there is very slight or even no increase of temperature over that of the sound leg. In acute jsleurisy and peritonitis the temperature of the inflamed cavity is the same as, or sometimes less than, that of the blood inside of the heart. The degree of heat in the inflamed part will difl'er materially according to the character of the inflammation. In the early stages of inflammation, when there is an active arterial hyperiemia, the temperature will be greater than in the later stages, when the active hyperannia has given place to stagnation. Also, in an intense inflammation ju-oduced in the rabljit's ear, in which there is stagnation and a great deal of hemon-hage in the tissue, the temperature, instead of being greater, may be considerably less than that of the opposite ear. In any experiments with regard to tem- perature in inflammation the temperature of the inflamed part must always be compared M'ith the temperature of the interior of the body of the same animal. A considerable amount of fever may be produced by even a comparatively slight degree of inflanunation, and if the tenijiera- ture of the inflamed part were simply compared with that of the usual normal temjierature of the animal, erroneous conclusions might be drawn. Pain in inflammation is due to the distention of the part and the ]iressure which is produced on the nerves, or by the direct action of the inflammatory cause on the nerves. The character of the pain will differ in different tissues of the body and in the various sorts of inflammation. In very acute inflammations, when the swelling has taken place rapidly, INFLAMMATION. 159 the pain frequently lias a marked pulsiiting eliaracter, because every addition of blood which is bi'ougiit to the part by the systole of the heart will temporarily increase the pressure on the nerves, and consequently the pain. It is evident that the pain in tissues poorly supplied with nerves will be less severe than in parts which are extremely sensitive. The anatomical character of a tissue will also have an influence on the degree and character of the pain, which may be entirely disproportionate to the abundanc^e of nerves. In inflammation of dense fibi'ous tissues, which are incapable of much distention, greater pressure and injury of nerves are brought altout than in a part where the tissues are more lax. Inflammations of the periosteum or of the fibrous tissues about joints are intensely painful. Not only do these local conditions iufluence the degree and the character of the pain, but general conditions of the body may also exert an influence. A condition of hypcraisthesia may be brought about either by local changes in the nerves of the inflamed part or by the efl'cct of fever on the nervous centres. The swelling of the inflametl part is due to an increase of material in the part. There is utit only an increased amount of fluid in the inflamed part, but the cellular elements are also increased. The volume of a part in the state of inflammation is also slightly increased by the increased amount of blood in the vessels, but this has so slight an influence that it may l)e left out of consideration. We know that hyperemia will produce an increase of volume. The fluid which is present in the in- flanuuatory tumor comes from the blood-vessels ; the transudation is increased. Not only does the fluid accumulate in the tissues in this way, but there is an increased flow in the lymphatics going from the part. Cohnheim showed that when a canula is placed in a main lymphatic of the leg after an acute inflaunnation has been produced in the foot by the action of crotou oil or hot water, tiiere is a greatly increased flow of lym})h as compared with the other side. On dissecting out the lym])iiatics coming from an inflamed part they are found full and turgid. Chemical analysis of the lymph in inflammation has shown that it is much more concentrated than the normal lymph. A solid residue of 6 or 7 per cent, has frequently been foimd in the inflammatory exudation in man, and Lasser has shown that tin- lymph from the inflamed foot contains 6| to 8 per cent, of solid constituents. The salts are not increased. All inves- tigators are agreed that they are found in almost the same proportions in the inflammatory transudations as in the normal lymph. The increased concentration depends entirely upon an increase in the amount of albumin. Tliere is a mai-ked ditf'crcnco lietwcen the character of the cedematous fluid in inflanuuation as compared with tliat of tiic ordinary dropsy from chronic passive <'ougestiou. The dropsical accumulations contain but little albumin, and the normal lympii has an intermediate relation between the two in the projiortion of albumin. In inflam- matoiy lym])h there is a greater tendency to coagulation than in normal lympii. Dropsical accumulations either do not coagulate at all or very slowly, and a soft clot is produced. Lasser found ditticulty in obtaining lymph from the lymphatics of an inflamed part on account of its great tendency to coagulation, the canula becoming in a short time filled with the clot. The increased coagulability of the lymph is due in great part to the increased number of colorless corpuscles. 160 SVIiaiCAL I'ATIKJLOGV. Cohnheim regards this altcratidii in the character of the transiulation as due entirely to alterations in tiie walls of the blood-vessels. The character of the filtrate is altered, because the character of the tilter, the wall of the blood-vessel, is altered. He rightly supposed that the increased transudation in inflammation is not due to a simple increase of jircssure within the vessels, because the character of the fluid is difl'erent from that in chronic passive congestion, which is due to such increase. It is impossible to compare exactly the character of the transudation in the two cases by observation of the fluid in the lympiiatic vessels. In chronic passive congestion the lymph as it escapes from the vessels comes in contact ^vith a tissue which is unaltei'ed. In inflammation the lymph comes in contact w'ith abnormal tissues. In the tissue of the jiart in which there is inflammation there are various changes taking place, ^•arious degenerations have been produced by the injury which has caused the inflammation, and all of these factors may exert an influence on the character of lymph flowing through it. It is probably true that in in- flammation the character of the transudation passing through the vessel- walls is diflei'ent from the normal, and difl'erent from that in chronic passive congestion. But its character is not due to changes which have taken place in the walls of the blood-vessels, in consequence of which they f)assively allow a ditt'erent fluid to pass through them, l)ut the vessels actively secrete a difl'erent fluid. The character of the transuda- tion may difier also in the various sorts of inflammation. A difl'erent fluid is needed by the tissues, and there will be a diiference in the tran- sudation, just as there is a difl'erent lymph secreted by the blood-vessels of the kidney as compared with that secreted by the blood-vessels of the pancreas. This increased flow of lym])h in inflammation has a ])urpose- ful character independent of afl'ording a greater degree of nutriment to the tissues. By it soluble chemical substances — substances either pro- ducing the inflammation of the tissue in the first place or substances which are produced in the inflamed area by the action of bacteria which may be there — are diluted or washed away. In the inflamed part the lymph will accumulate in the interstices of the tissue, in the lymjjhatic vessels and lymph-spaces, and give rise to oedema of the part. By pressure it may be pushed from one place into another, just as by pressure the blood can be removed from the ves- sels of a part. A deep dei)ression or pit remains at the seat of pressure, which w'ill disappear when the fluid returns. There may be inflam- mations in which the swelling is due entirely or almost entirely to the increased fluid transudations. Such inflanmiations may be spoken of as cedematous inflammations, and they generally represent a milder degree of inflammation. One of the most marked examples of a simple cedema- tous inflammation is that produced by the action of the sun. We may have here a very mild degree of inflammation in which there is only hypersiemia with increased fluid transudation. Samuel, in his work on inflanunation, has very properly separated the cedema in an inflamed part due to the inflammatory cause from the a?dema in adjacent parts which frequently supervenes on inflammation. Thus, when the extremity of a rabbit's ear is inflamed there will be cedema not only in the inflamed portion of the ear, but also lower down in the ear, where no injury of the tissue has been produced. This INFLAMMATION. 161 Samuel distinguishes as inflammatory oedema in contradistinction to the cedematous inflammation. It is due merely to an extension of the a?dema from the inflametl territory, and is sometimes spoken of as collateral cedema. The same thing can be seen in tiic sulicntaneous (edema of the chest-walls which sometimes accompanies inflammation of the pleura. This oedema was also studied fully by John Hunter, who speaks of it as being s([ueezed from the inflamed part into adjacent parts. The tumor contains, in addition to tlie fluid, a certain portion of solid material. In the first place, it contains a varial)le amount of fibrin. Not only is the lymph which passes from the inflamed part richer in fibrin than the normal lymph, but in many inflammations tliere is formation of fibrin, a certain amount of coagulation, in the inflamed part itself In the inflannnatory exudation all the necessary elements for the formation of fibrin are present. P^ibrin is due to the action of a ferment, usually spoken of as the fibrin-ferment, on certain substances in the blood. This fibrin-ferment, there is every reason to believe, is formed from the disintegration of cells. In the ordinary process of coagulation it is probable that the leucocytes of the blood form the source of the ferment, l)ut it may be ]iroduced by the disintegration of the cells of the tissue. In the inflamed part there is an abundance of fibrinogen in the exudation, and tlie fibrin-ferment is produced by the disintegration of cells. Fibrin is present in almost any acute inflam- mation. On examination of the inflamed car of the rabbit after suit- able hardening a varying amount of fibrin is found in the exudation, the amount depending largely on the intensity of the inflammation. In some (;ases there are only a few fibrillte scattei'ed through the tissue, and in other cases there are large masses of it. In many cases the fibrin may be seen radiating out from the ni'crotic cells. The hardness of the inflamed part, especially the so-called brawny induration which is found in certain sorts of inflammation, is due to the presence of fibrin. In certain forms of inflammation the fibrin may be present in excessive amounts. In any inflamed part in which there is an increased number of cells in the tissues a certain number of red cor})uscles will nearly always be found. With regard to these we know that they could only come from the blood-vessels, and they are found in vai'ving numbers, dependent on the character and intensity of the inflammation. In some cases they are present in such excessive numbers that the inflammation is spoken of as hemorrhagic. These corpuscles escape into the tissues from tlie capillary vessels, and can easily be seen to pass tlu'ougli tlie M'alls of these vessels when the inflammation is directly observed under the microscope. A large jiroportion of the cells — and in some inflammations nearly all — are white corpuscles which have emigrated from the vessels. With the increased knowledge of the corpuscles of the blood which has come from its more careful study in recent years we know that the white cor- puscles ditt'cr materially fr(im one another in form, and that they have difl'erent values and diflerent origins. Tlie most numerous corpuscles are tlie so-called polynuclear leucocytes. These form between 80 and 85 per cent, of the entire number of leucocytes, and are cha- racterized by an irregular nucleus. This nucleus stains brightly, and, although spoken of as a multiple nucleus, it is in most cases a single Vol. I.— 11 162 SURGICAL PATHOLOGY. nucleus divided into several masses wliieli are connected together by fine tilaments. These corpuscles also differ from one another in the chem- ical composition of their protoplasm. This is shown by their reaction to staining agents. In the great majority of them the protoplasm con- tains very fine granules which are stained with the neutral or basic aniline colors. In a certain proportion of them the granules in the pro- toplasm are larger and stain brightly with eosin. Next to these in number and importiuice are the so-i:alled leucocytes of the blood. In these two sorts can be distinguished. The most numerous arc corpuscles which are about the size of the cells contained in the lymph-glands, and which have a large round nucleus, and a very small amount of proto- plasm around this. There are a certain number of larger cells of the same character. Although other cells have been described in the blood, these are the only ones which need concern us in the study of inflamma- tion. In the corpuscles first described the nucleus frequently takes the shape of a horseshoe. The polynuclear leucocytes are the most numerous of the cells found in the swollen tissue in acute inflammation. In some cases they are ap- parently the only new cells found iu the tissue. In the inflamed cornea in the early stages of inflanmiation the cells found in the lymph-spaces are exclusively those. There have been many theories advanced to explain how these cells pass through the walls of the vessels. The first idea held by Cohnheim was that the passage was effected by means of their amoeboid movements — that they crawled through the walls. The corpuscles when adhering to the walls before the emigration has begun show active amceboid movements, and when in the act of passing through, both the part outside of tlie vessels and that inside show active amceboid motion. Cohnheim afterward gave up this idea, and con- sidered that the white corpuscles, like the red, did not pass through by means of their own activity, but l\v passive filtration. He was chiefly led to this view from the fact that when the blood-current ceased in the dilated veins the process of emigration ceased. There may be another explanation of this. The leucocytes are probably kept against the wall of the vessel by means of the blood-current, and probably by the con- tinuance of the circulation they are excited to moi'e active amoeboid movements. Their collection in the vessels of the inflamed part is partly due to the slowness of the circulation, but more to a voluntary action on their part. The inflamed tissue exerts an attraction for them. Substances which have the power of stopping the amceboid movements of the corpuscles also stop the emigration. Thoma has shown that when salt solution of the strength of 1 : 12 is injected into the blood the amoeboid movements of the leucocytes cease, and the process of emi- gration ceases in inflammation. If the frog is completely chloroformed, the action of the chloroform may extend to the leucocytes and stop any amceboid movements, and emigration will not take place. Cohnheim supposed that the filtration of the corpuscles through the vessels was due to an alteration in the vessel's wall, together with the increased pressure. He did not attempt to define the character of this alteration, Ijut supposed it might be physical or chemical. The most accurate observations on this subject seem to show that the leucocytes pass between the endothelial cells of the vessels. There are small openings IXFLAMMATIOX. 163 between these cells in the normal condition of the vessel, and these V)jienini;s prol)ably become laraer when the vessel is dilated. lionciiard thinks tiiat the endothelial cells in the vessels may contract and assnnie a round form, leaving large openings between them through which the corpuscles pass. The emigration of the leucocytes is due to active amoeboid movements on their part, possibly assisted by a more porous condition of the walls of the vessel. It is known that eheniii'al substances liave the power of attracting or rc])elling cells capable of indciiendcnt motion. This \vas shown first by Engelman in certain of the myxomycetes. It is seen in a marked degree in bacteria. The phenomenon was carefully observed in the leucocytes bv Gabrischweisky. He found that when capillar}- tubes were partly filled with certain substances and placed in the tissues of animals, the tubes became filled up with leucocytes. When they were filled witii indifferent substances, only a small number of leucocytes entered into them, and other substances exerted a repellant action. Necrotic tissue of all sorts attracts tiie leucocytes to it. No better proof can be given of this than the collection of leucocytes around a lesion in the centre of the cornea. Althougli they pass from the vessels of tiie sclera, tliey do not wander into the tissue at random, but march directly to tlie inflamed focus. Wiiat the nature of the chemical substance is which exerts tiiis attraction for the leucocytes we do not know. It is jjroduced in necrotic tissue everywhere. Although most of the bacteria have a decided action in attracting leucocytes, this attrac- tion is more strongly exerted when they are dead than when they are living. It is prol)able tliat substances are produced in the necrotic tissues whicli by diffusion extend tiieir action to the vessels, producing in these the inflammatory phenomena. Not only is the influence felt on tiie vessels, but it extends to the cells within them, causing these to pass through the walls and to accumulate around tiie necrotic tissue. Tiie cells in some inflammations, ami in tlie early stages of all, are composed entirely of tliese polynuclear leucocytes. Along with them in other cases cells similar to the lympliocytcs in the blood appear. Usually they appear somewhat later than the polynuclear leucocytes, and in inflammations of a less active chai-acter. They are principally formed in the outermost zone of the inflammatory area, and usually are seen in small groujjs around the vessels. There is mucli dispute about their origin. While all observers are agi'eed that tlie polynuclear leuco- cytes come from tlie blood, it is held by some that the small lymphocytes have the same origin. Others iiold tliat they are formed by prolifera- tion of the tissue-cells. Baumgarten especially holds the former view. His studies of the cells in inflammation were «iade on the histogenesis of tubercle. Tlie round ]ym])liocytes enter largely into the structure of this, and lie believed tliat they come from the l)lood and enter into the tubercle, which is at first formed of large cells derived from the tissue. Ribbert and Marchand also believe that these cells arc leucocytes. In the more chronic inflammations the new cells may be almost exclusively of this character. There are many objections to these views. Although we are not able to study the course of inflammation so thoroughly in man aii])mcnt observed by killing the animals at successive periods after the injection. Sucli foci will serve as general types of acute inflammation. The micrococci are found in a small vessel, either a capillary or a small vein, wliicli tliey entirely occlude. They are ])roI)ab!y not lodged here as an emliojus filling up at once tlie entire vessel, but one or more lodge in tlic endothelium and the vessel becomes filled by their gro\\th. In tlie older foci tlieir growth extends beyond the vessel, and clumps of tliem may be found in the tissue. Around tlie group of bacteria tliere is a distinct necrosis of the tissue. In the necrotic mass the cells may sometimes be recognized, Init more generally the whole is converted into a granular mass. In the periphery of the necrosis the tissue is infiltrati'd witli polvnuclear leucocvtes. Tliese form a wall aronnd and extend into the necrotic tissue. It is probable that the necrotic tissue is formed, to some extent at least, by the leucocytes which have wandered into it so far that they have fallen victims to the same cause which jirodueed the necrosis of the tissue. Although the wall of cells formed around the necrosis is, on 166 SURGICAL PATHOLOGY. the inside, composed entirely of" leucocytes, on the outside these gradu- ally give place to mononuclear cells similar to the indifferent cells of granulation tissue and to the lymphoid cells of the blood. The more advanced the inflaniniatiun, the more numerous arc they in the tissue. If tlie animal be killeroperties than as a swelling. In cartilage, in which tiiere are no distensible meshes or canals, the exudation-fluid or corpuscles cannot enter into the tissue ; therefore in inflammation of the cartilage of joints the exudation is found in the cavity of the joint, except in the immediate periphery, tiiere under certain circumstances a few corpuscles apparently eat tlicir way directly into the tissue. When the wall of a large cavity is inflamed the inflammatory exudation accumulates in tlie cavity. That is the case in the serous membranes, also in the dura mater. In the inflammation of periosteum the exudation cannot accu- mulate in tlie dense tissues, but it presses in beneatii the periosteum, ele- vating it from the bone. The inflammatory exudation always accu- mulates where it finds tiie least resistance ; thus in ])neunionia it enters tiie alveoli of the lungs and fills up these, because it finds no place in the alveolar sejita. In the same way, it is easily understood that in places where a dense covering prevents the exudation reaching the free surface this covering will be elevated in tiie form of a bladder or vesicle. Tiiis is seen in tlie example we have given in the inflammation of the peri- osteum, but a l)ettcr example is given in the inflammation of the skin. In all forms of acute inflammation of the skin one of the most common of all phenomena is to find the epidermis over the inflamed area elevated in the form of a vesicle. In organs which freely communicate with the outside, and an open way is given for the exudation, it is sinijily poured out on the surface and escapes. This is the case with all mucous mem- 168 SURGICAL PATirOLOdV. hi'iUK's, beoausc their cpitlielial cdvcriiiL!; is loose ami docs not hold tlie exiidation within it as does tiie epidermis. In consequence of this a formation of vesicles does not take place, but the exudation passes freely tin-ough to tiie surface. This is also tlie case in the kidneys, where tiie exudation in ))art passes otl' in the urine and ajijjcars in the form of albumin. Inflammation lias l)een divided into two varieties, depending upon the special involvement of certain elements of an organ. In a glandular organ we can recognize the secreting cells and the connective-tissue framework supporting the cells and carrying the blood-vessels. Accord- ing as the special seat of the inflammation was supj)Osed to inv(dve the specific glandular cells, the j)arent'hyina, or the interstitial tissue, the division has been made of parenchymatous and interstitial inflamma- tion. This division is a false one. If we regard inflammation as the sum of the processes which take place in the tissues on receipt of an injury, it is obvious that we cannot have inflannnations so divided. It is hardly possible to conceive of an injury which will affect exclusively one or the other of these constituents of an organ. There is no doubt that under certain circumstances there may be accunndations of cells in the interstices of an organ due to growth of the intercellular tissue, as in some of the pathological conditions met with in the kidneys in scarlet fever. It cannot be held that all growth in connective tissue is due to regeneration following a primary lesion. In such kidneys there are few or no lesions of the epithelium of the tubules. In certain liver diseases a similar ])r(>liferation of the connective tissue may take place. AVe have generally been accustomed to speak of such ct)ntlitions, in which we find a cellular infiltration of the tissue, as inflammation, but there is no reason why they should be so considered. The ])rolif'eration of the connective tissue may be due to the direct action of Iwcteria or their chemical jirod- ucts on the tissue, or to other influences producing it without any jire- ceding injury. Inflanmiation of a mucous membrane is spoken of as "catarrhal inflammation." Virchow used the name to denote increase of func- tional activity of a mucous surface. The word "catarrhal" is used so loosely that it is difficult to define it. AVe may use it to designate mild degrees of infianunation of mucous surfaces in which there is neither idceration nor any distinctly characteristic exudation, sucli as a fibrinous or a purulent one. In inflammation of the intestinal canal the word is generally used to include inflammations the etiology of which is un- known. The increased amount of fluid which comes from an inflamed mucous surface has two sources. In the first ])lace, the mucous mem- brane has not a dense tissue on the surface impervious to fluids, like the horny layers of the skin, and an increased amount of exudation in the subcutaneous tissue readily finds its way to the surface instead of accu- mulating in the interstices of the tissues. A mucous surface is like a serous surface in this respect. In the next place, the jjroper secretion of the mucous surface is increased. This is in part due to the hyj)cr- semia of vessels su])plying the glands, and possibly in ])art to a direct stimulation of the glands by the inflammatory cause. The cells may be influenced to increased action in the .same way as the blood-vessels are. In most cases the serous exudation from the vessels of the tissue lyPLAMMATIOy. 169 is accoiiipanicfl bv emigration, ami the leucocytes pass as readily through the epithelial layer as does the serum, and api)ear in the Huid on the surface. A more suitable classification of inflammation is one based on the character of the exudation. The character of the exudation is largely determined by the cause of the inflammation and the intensity of its action. The causes are so manifold that it would be impossible to give an etiological classification. Tlie exudation in inflammation may be almost entirely serous, and such inflanmiations arc sjioken of as edema- tous or serous inflammations. In any inflammation the (piantity of serous exudation is increased. The tissue in serous inflanunation is infiltrated with fluid. The increased transudation represents the reaction of the tissue to a mild injury. One of the best examples of it is the inflam- mation of tile skin which follows prolonged exposure to the sun. The injection of tlie vessels is extreme and the skin is swollen and pits on pressure. Most of tlie exudation accumulates in the meshes of the tissue, but a certain portion passes to the surface and elevates the epider- mis in the form of smaller or larger vesicles. The vesicles are filled with a clear transparent fluid which on microscopic examination shows few cellular elements. If the cause be removed, the contents of the vesicles will be absorbed. The action of the sun has probaljly been to produce sliglit injury of tlii' upper layers of the epidermis, in some cases extending more or less deeply into the tissues below. In some cases extensive necroses e.xtendiiig through the skin, which are followed by all the phenomena of intense inflammation, may be produced. There is increased serous transudation in the beginning of every inflammation. In pneumonia, congestion and i)a((ue fluid of varying degrees of density. It may acquire a reddisii tinge from an aihnixture of red corpuscles ; in some cases it has a distinctly j'ellowish or bluish tinge, the latter being due to certain of the bacteria which cause suppuration. The exudation may infiltrate in the tissues — that is, it may be contained in the meshes of the tissues, as in the serous exudation — or it may be contained in cavities which are hollowed out in the tissues. 8uch a cavity containing pus is called an abscess. Or, again, there may be a loss of substance on the surface from which such a fluid exudes. In all other forms of inflammation, particularly in the more severe forms, there is more or less fil)rin in the exudation. In the purulent inflammation the exudation contains either no fibrin at all or only a small amount of it. Moreover, the exudation differs in the eftect which it has on the tissues of the inflamed part. In the serous and fibrinous inflammations the exudation either accumulates in the interstices of the tissue, or, if it cannot be con- tained in this, it passes to the surface or into the natural cavities of the body, always following the path of least resistance. The exudation in itself seems to produce no injury to the tissue. The tissue, of course, may be injured by having its nutrition interfered with by compression of vessels produced by the exudation, and very extensive necrosis may be produced in this way ; but the exudation in itself produces no injurious action on the tissues with which it comes in contact. The purulent inflammation is different. In this there is not only destruction of cells by the exudation surrounding them, l)ut the intercellular substance itself is destroyed and dissolved by the exudation. The exudation and the softening and destruction of the tissue combine to form the abscess. The dissokition of the intercellular substance takes place more easily in the loose areolar tissue. Not only is this solvent action of the exudation exerted on the intercellular substance, but the fibrin also, when any is present, is dissolved in it. "We can easily follow the course of development of an abscess by injecting some of the bacteria, which from their specific action are spoken of as the pus-organisms, into the ear-vein of a rabbit. The organisms are carried into various tissues, and by their growth form small masses in these. The first ett'ect of the presence of the organisms is the production of necrosis in the tissue innnediately surrounding them. This is accompanied by an enormous emigration of leucocytes extending into the necrotic tissue, and the leucocytes to a great extent undergo the same necrosis as the tissue. In the pcri]ihery they form a more or less distinct wall around the necrotic tissue. In the necrotic area itself there is of coui-se no inflammation. Not only are the cells destroyed, but the blood-vessels as well, and no circulation takes place within the jiart. The next stage in the formation of the abscess is the liquefiiction of the tissue. The bacteria or their chemical products appear to exert an actual dissolv- ing power on the tissue. First, apjiarently, the intercellular substance is dissolved, and all of the cells, both those of the tissue and the leucocytes, come together to form a single mass. Sometimes the tissue-cells more or less retain their fcn-m and can be recognized, but more often they are broken up into fragments or granules. In some cases the suppuration INFLAMMATION. 173 does not spread from a single point in tliis way, but from several adjacent points. Then the various foci of softening come together, forming a single cavity, which may contain not only the individual cells which have been set free by the dissolution of the intercellular substance, but larger masses of tissue into which the softening has not fully extended, and which are set i'ree by the various foci of softening meeting one anotiicr. The various tissues show a varying resistance to this softening power of the exudation. In a glandular organ the comiective-tissue septa in the gland offer the least resistance. The suppuration may extend along these, and an abscess be formed which will ct)ntain large necrotic masses of the glandular substance. Such masses are spoken of as sloughs. The pus varies in consistence. Sometimes it is thick and creamy, at others it is thin and similar to a serous exudation. The cells are to a large extent the white corpuscles of the blood. Of course along with these cells there will be otlier cells and fragments of cells which come from the tissues. When the pus-cells are examined on the warm stage of a iuicrosco]ic many of them show acti\-o amreboid movements. The fluid portion of the pus is simply the serous exudation. The pus con- tiiined in a definite abscess-cavity is frequently under considerable ten- sion, sometimes apjiarently much higher than the blood-pressure. On Fig. 6. m c b '.■■■>.:.

When the abscess-cavity has remained for some time a definite wall is formed around it, which prevents its further extension (Fig. 6). As the abscess is forming there is constantly going on outside of the necrosis antl outside of the wall of leucocytes a gro\\th of the tissue. All of the cells of the tissue, the connective-tissue cells, those forming the walls of the blood-vessels, and ]>robal)ly also the specific cells of the tissue, proliferate. In consequence of this proliferation there is produced a dense tissue consisting to a large extent of cells 174 SURGICAL PATHOLOGY. ■similar to the lymphoid cells of the hlood. This is the sjime tissue which forms the small projeeting granules seen on the surface of an ulcer, and from this it has received tlic general name of granulation tissue. Sometimes softening does not take place until such a definite wall is formed around the focus. This action on the part of the tissue varies in different cases. Sometimes it is almost entirely absent, and there is nothing oj)posed to the extension of the ])rocess. In some cases it would a])pear as tiiough there were a direct excitation of cell-]MX)lifcr- ation of the tissues produced by the bacteria. Such a membrane lining an abscess is called a "pyogenic membrane." It is a soft reddish mem- brane having a slight similarity to a mucous surface. It was formerly supposed that pus could be directly secreted by such a membrane. It always contains, along with the cells derived from the tissue, a large number of leucocytes, which are constantly passing through it into the abscess, and in the vessels not only of the membrane itself, but in those of the surrounding tissues, there are quantities of leucocytes. In many cases the membrane does not -offer sufficient opposition to the advance of the suppurative pi'ocess. The cells composing it may become necrotic, soften, and form part of the contents of the abscess, and its formation gradually recedes as it is gradually destroyed. There is no sharp limit to the membrane-f(jrmation, but it gradually fades off' into the surrountl- ing tissues. For a considerable distance around, the formation of gran- ulation tissue continues, appearing as an infiltration of the interstitial tissue with small round cells. Sometimes the purulent inflammation is preceded by a fibrinous or serous inflammation. The fibrinous inflam- mation of a serous surface may become changed into a purulent, and the fibrin which has been formed becomes dissolved in the pus. There may be a large amount of fibrin in the tissue surrounding an abscess which may become softened by the advance of the suppuration. We may distinguish various sorts of abscesses, depending on the cha- racter of the pus and the character of the tissue in which it is formed. When an abscess forms rapidly and is accompanied by a considerable amount of jiain and evidences of acute inflammation, it is spoken of as an acute or a hot abscess. On the other hand, the abscess-formation may take place slowly, the pus may accunudate slowly, and, if this takes place in an organ poorly supplied with nerves, it may not give rise to any special symptoms. Again, the pus may be formed in one portion of the body, and may by gravity extend into a jiortion lower down, gradually dissolving the tissue as it passes along. Such an abscess is called a cold or gravity abscess. One of the best examples of this is the abscess which appears in the inguinal region, the pus being formed in the vertebra? and descending along the psoas muscle. The amount of pain in purulent inflammation differs greatly. In feome cases it is intense ; it others it may be entirely al>sent. This depends largely upon the character of the tissue and the amount of nerves in the part. In an abscess of the subcutaneous tissue, where pressure is exerted on the nerves of the skin, the pain may be intense. In abscesses in internal organs poorly supplied with nerves, as in the liver, a large abscess may be formed without any pain accompanying it. The pain will also, as in an ordinary inflanunation, depend upon the amount of pressure which is exerted on the nerves. In a tissue capable INFLAMMA TION. 1 7 5 of distention there will be less pain than in a firm, dense tissue. Ab- scesses of bone and of the periosteum are accompanied by intense jiain. The amount of i)ain will also depend upon the rapidity with which the abscess is formed. If the pus accumulates rapidly, the pain will 1)C more intense ; if it accunuilatcs slowly, the tissues can gradually become accustomed to the ihstcntion. Inflammation produced by Bacteria. The action of almost all pathogenic bacteria is closely related to intlammation, because such bacteria in general produce an injury to the tissue where they are present. The inflannnations which arc produced by bacteria are also in some ways ditferent from the chemical or mechan- ical inflammations. Bacteria may act on the body in a vai'iety of ways. In the first place, the organisms may enter directly into the blood, and there find suitable conditions for their growth, or, without growing in the blood, may be deposited by it in the ditferent organs. In most cases there is a primary lesion produced, and the infection of the blood follows from this. In consequence of this the bacteria may be deposited in the various organs of the body, and foci similar in their general nature to the primary focus of infection may be formed. A distinction must be made between the cases in which the organisms grow in the blood and the cases in which they may enter the blood, l)ut do not find there suitable conditions for their growth, and the blood simply acts as a carrier, depositing them in various organs, where they exert a local action. When the organisms enter into the blood the condition of septi- cemia is produced. Many of the pus-organisms have the power of infect- ing the blood, and septicemia is most frequently found as an accompani- ment to some one of the purulent affections. In many cases the danger of septicfemia seems to stand in inverse relati(jn io the extent of the pri- mary infection. The more develojjed the local infection, the less apt the septicemia is to take place. Frequently the same organism which causes a typical local disease in one animal will produce septicemia in another. In man inoculation with the anthrax bacillus will always produce an intense local inflammation at the point of inoculation, the anthrax pustule, which is only exceptionally followed by septicemia. Most of the local lesions produced by bacteria are distinctly infianuna- tory in character. This is eminently the case in most of the acute infectious diseases ; for instance, in anthrax, in diphtheria, in pneu- monia. ]\Iany of the inflammations so jiroduced are j>urulent in cha- racter. In other cases lesions very closely related to inflammation, or which at scmie period of their course arc accomiianicd by inflammatinn, will be produced. The lesions which arc produced by the tubercle bacillus and by the typhoid ba^'ilhis arc at first not inflammatory in character. The lesions consist in a new formation of tissue of a definite type, which arises from proliferation of the fixed cells of the tissue. In the bi'ginning of these formations then; may be n(j emigration of leuco- cytes and no inflammatory lesions in the tissue. At a later period, however, in each, necrosis and degeneration take place in this newly- formed tissue, and with this the inflammatory phenomena begin. In ty])hoid fever the lesions, in the first place, consist of a new formation 17G SURGICAL PATHOLOGY. of lym])lioid tissue arisinti; from tliu lyiiiplioid tissue of the iutestiual canal. lu this lymphoid tissue there are no leueoeytes, and, althdugli tliere may be hyperceniia of the surrounding biood-vessels, there is no emigration of leucocytes and no increased exudation. It is only when necrosis takes place in the hyperplastic tissue that the invasion of leuco- cytes begins. The .same is true in tubercle. Emigration only begins and leucocytes are only found in the tuberculous tissue when caseation appears. The necrosis whicli arises in a specific tissue in this way appar- ently has the same attraction for the leucocytes as has necrosis of normal tissue. The same thing is true of the new formations not caused by bacteria. Many of the tumors are accompanied by intlanmiation in the surrounding tissues, and even in the tumor itself there may be emi- gration, an increased exudation from the blood-vessels ; and this is closely connected witli processes of degeneration in the tumor. These processes may be related to inflammation in another way. Thus the tubercle may excite inflanunation merely by its presence. It may pro- duce by its presence injuries in the ti.ssue which will be followed by inflammation, and which may not be immediately connected with the bacteria. The character of the inflammations produced by bacteria will be largely influenced by the manner in A\hieh these gain entry into the system. This may take place in various ways. They may enter into the tissues, producing an inflammation at the point at which they enter, or they may produce no local lesions at the point of entry, and be carried by the blood to various tissues of the body and deposited there, only producing lesions in the tissues for which they have a specific aflinity, which is probably due to tlie fact that certain tissues offer them the mo.st suitable conditions for their growth. This is the case in small- pox and in scarlet fever. Although we do not know anything about the virus of small-pox or of scarlet fever, it is exceedingly improbable that the lesions of the disease could be produced by bacteria finding entry through the skin. The same bacteria do not always act in the same way. In general we are able to surmise from the character of an infiannnation what is the s{)ecific organism which has caused it ; but there are exceptions to this. The .same organism whicli causes a typical fibrinous inflammation in the lungs may under some circumstances produce a distinctly purulent inflammation Mithout any formation of fibrin at all. One of the ])us-urganisms, the streptococcus, may pro- duce in the pharynx as typical a fibrinous infiannnation as is produced by the diphtheritic bacillus, while under other conditions it may form an abscess. The bacteria may also be related to inflammation in another way. They may produce local lesions, and there may be ]>roduccd in these local lesions chemical poisons which will ]n'oduce necrosis and degeneration in distant organs, and these may be followed by inflammatory phenomena. The most typical inflannnations are ])ro- duced by a group of organisms which are so closely related to sup])uration that they are called the pyogenic or " pus-organisms." Suppuration may under certain circumstances al.so be produced by a nimiber of other organisms. The essential pus-organisms are the staplu/lococcus aureus, the streptococcus pyogenes, the sfapht/lococcus cpklermidis albus, the bacillus pyogenics fcetidus, and the bdci/lus pyocyaneus. In addition to INF LA MM A TION. Ill these suppuration has frequently been found to be pi'oduced by other organisms ; for instance, by the colon bacillus, by the tubercle bacillus, by the clip/ococcus lanceolatus, l)y the baci/hui proteus, and by various others. The most typical purulent inflammations are those produced by the staphylococcus and the streptococcus. In the case of the staphylo- coccus its action has been thoroughly investigated by experiments both on man and animals. The most typical influnnuation in man produced by it is the ordinary boil or furuncle. In this it is evident that the bacteria find their way into the skin along the hair-follicles or the sebaceous glands. It has been found that the mere application of the organisms to the surface of the skin is not followed by any results. When they are rubbed into the skin the typical furuncle may be produced. They apparently do not enter into the skin by means of the sweat-glands, and furuncles do not appear on the parts of the body where there are no hair-follicles or sebaceous glands, as ou the jialni of the hands or the soles of the feet. They are most apt to a])pear on portions of the body which are subjected to the rubbing of clothing, as at the back of the neck and the waist-line. There is first produced a necrosis of the tissue in the neighborhood of the hair-follicles or gland, and around this suppuration. The necrotic tissue which produces this does not always li([uefy, but remains as the so-called core of the furuncle which is cast out with the pus. The pus produced by the staphylococcus, as a rule, is thick and creamy, fi'equently M'ith a distinctly yellowish color, probably due to the pigment produced by the organisms in their growth. The streptococcus has a greater variety in its action than the staphyhjcoccus. The streptococcus may produce on the surface of mucous membranes a typical fibrinous exudation, or it may produce suppuration of the tissues. Its action, even in producing suppuration, is not circumscribed, as is the action of the staphylococcus. Typical suppuration with liquefaction of the tissues is not so apt to be produced, and the pus has not the thick creamy character of that of the staphylococcus. In many cases no suppuration at all is produced, but simply an infiltration of the tissue with serum and leucocytes. When suppuration is produced by the streptococcus ]\i/ogencs it usually takes the form of purulent infiltration. Strciptococci may be found in the tissues even outside of the line of leucocytes, and they do not produce so much necrosis, nor do they themselves exert such a positive chemotaxis, as do the staphylococci. Both the streptococci and staphylococci may produce on serous surfaces extensive suppuration. On both serous and mucous surfaces the inflammation produced by the streptococci is accompanied by a greater formation of fibrin. The inflammations produced by the streptococci are, as a rule, far more dangerous in their local and in their general eflects than those produced by the staphylococci. Inflammation of the uterus in puerperal fever is almost alwaj-s due to the action of the streptococci. Inflammations produced by bacteria show in one way a vast differ- ence from those produced by the action of chemical and mechanical causes. In inflammation produced by mechanical causes the action of the cause ceases with the inflannnation. It is impossible that it should extend to other parts of the body. Tlie bacteria may be in various wavs carried from one portion of tiie body to another, and wherever they Vol.. I.— 12 178 SURGICAL PATHOLOGY. come tliey produce tlie same character of inflammation as in the primary focus. Those inflammations wiiich apj)ear in the dift'erent portions of tiie body following a primary focus of inflammation are called second- ary or metastatic inflammations. The organisms may jjass along the course of the lymphatics, either producing inflammations in places ooiniected immediately with the primary focus by means of the lym- pliatics, as the lymphatic glands, or they may be carried by the lymphatics into the blood and then into other organs. They are most apt to be retained in the nearest lymphatic glands and excite these to inflamma- tion and sui)paratit)n. As an example of this we have the buboes in the groin which follow local processes in the external genitals. The lymphatic glands may also be excited to inflammation by other products than the bacteria. The chemical products which are produced in the inflammatoiy focus are washed out by the exudation and carried by the lymphatics to the lymph-gland, where they may excite inflammation. Such inflammations are rarely followed by suppuration, anil the changes in the gland more generally consist in hyperplasia and the formation of a new lymphoid tissue. When the organisms enter into the blood they are carried into all of the organs and tissues of the body. But there is a decided difference in their action in the different tissues. Certain of the tis,sues are more lial>le to have these secondary abscesses following on blood-infection than others. When the staphylococcus aureus is injected into the ear- vein of a rabbit, the metastatic abscesses take ])lace in diflerent organs. The organisms of course first find their way into the blood-vessels of the lungs, but here it is extremely rare that we ever find any lesions pro- duced by them. The secondary foci of inflammation, the abscesses, are generally limited to the kidney and to the myocardium. They may also develop in the muscles of the body, but here, again, the preference is shown for certain regions. The muscles most frequently attacked are the abdominal muscles. It is difficult to explain this. The frequency with which certain organs are attacked may be due in large part to special diflerences in the circulation of these organs. In both the kidney and the heart the arteries are terminal ; that is, each porti(in of the tissue is snpjjlied by a distinct artery without anastomoses. The same condition obtains in the spleen and in the brain, but altscesses only rarely develop in these parts. It cannot be due to the greater facility with which the organisms are deposited in certain organs. All sorts of very finely-divided foreign bodies entering into the blood are deposited with greater facility in the liver than in any other organ, because here there is an enormous system of cajiillaries with very slow circulation. It is probable that the organisms find in the tissues of certain organs more favorable conditions for development than in others. The organ- isms appear to be rarely carrietl as large embolic masses plugging up blood-vessels. In the kidney there is little doubt but that they do act partly in this way, and the effect of their sjiecific presence may be accom- panied by the mechanical effects of infarction. They are not carried as embolic masses, because, even if they were injected as such into the veins, they would not be able to pass through the blood-vessels of the pulmonary circulation. In the kidney their action has been closely studied by Ribbert. It is probable that they lodge in or are taken up INFLAMMATION. 179 at some point in the circulation by the endothelial cells of the small arteries, and by their continuous growth they may plug up the vessel, and from this primary focus they may be carried as masses into smaller branches of the same artery. The secondary inflanuuation may be pnjduced in another way. The bacteria may lind entry into the tissue along various ducts or canals which lead from the j)rimary focus into other poi'tions of the body. The most typical example of this is given in the secondary abscesses which develop in the kidney following a primary purulent inflammation of the bladder or of the urethra. The organisms make their way from the bladder into the kidney in a direction opposed to the flow of the urine. It is probable that their progression is due to a gradual gi-owth along the wall of the urethra and of the pelvis of the kidney. They may do this without producing any inflammation of the urethra, but most often there is a general inflammation of this ; or it may be that they find suitable conditions for growth in the urine in the urethra, and infection may follow in this way. Rinne includes among the metastatic abscesses those produced by the action of bacteria which enter the body without producing any lesions at the point of entry, and are often carried into remote organs, where their action takes place. There is the greatest diversity in the effects produced by the pyogenic organisms. This is due to a number of factors, and, although much light has been thrown on the matter by experiments on animals, there remains much which is not at all or imperfectly understood. As a result of the entry of the same organism into the system there may be no effect produced ; or there may be a slight inflammation not leading to suppuration or more or less extensive abscess-formation ; or without deflnite abscess-formation an extensive and difi'use purulent infiltration of the connective tissue; or without the production of any local lesions there may be a general infection of the blood, and death may take place in two or three days with the phenomena of an acute intoxication. I saw during the last year a case in which a surgeon died several days after an operation on a case of peritonitis. There was no history of a wound received at the time of operation, and no definite point of entry for the organisms could be found at the autopsy. The most extensive lesions were in the right thigh and extended from this up to the buttocks. Over these parts there were large blebs and ])artial desquamation of the epidermis. The subcutaneous tissue and the adjacent muscles Avere necrotic and contained masses of streptococci. The same organisms were obtained in pure culture from the Idood and from every organ of the body. The infection very probably took place from the thigh, and the organisms possibly entered from a scratch with the nail or in some such way. There was no definite suppuration, and in the necrotic tissue of the muscle there were but few leucocytes. In any attempt to explain such variation in action the resistance of the tissue must he considered. This resistance is due to a number of things. The blood-serum is directl)' destructive to a number of organ- isms, and when they are subjected to its action, in some cases for a few hours only, they are destroyed. Also, there is no doubt that the leucocytes play a most important part in destroying the bacteria, in pre- venting their absorption, and in warding off their action from the sur- 180 SURGICAL rATHOLOar. rdiiiKlino; tissue-cells. It is probable that this action of the leucocytes is not the only way that tiie body has ul" combating tlie organisms, but it plays an important part. Ditiferent animals have ditt'er(>nt degrees of susceptiljility to the action of bacteria. It is probable that this is largely due to differences in the destructive powers of their serum. The number of organisms which are introduced into tlie body has an im])ortant influ- ence. This is shown by the results of the injection of tiie staphylo- coccus into the ear-vein of a rabbit. If the organisms injected are of the same degree of virulence, the effect produced is lai'gely dependent upon the amount of the culture which is injected. Very small doses may produce no effects. The tissue into Mhicli the organisms are intro- duced is of importance. After the injection of the staphylococci into the car-vein of a rabbit abscesses are tlcveloped in certain organs only, and this cannot be explained by the organisms entering these organs only, for other organs are equally exposed to their action. The same thing is seen in the direct injection of the organisms into the tissue. The smallest drop of a pure culture of the staphylococcus injected into the anterior chamlier of the eye of a rabbit is sufficient to develo]i an exten- sive supjiuration, with loss of the eye. A much greater quantity is neces- sary to produce an abscess when the injection is made into the loose subcutaneous tissue of the back than is required when the injection is made into the dense tissue of the ear or into the muscles. This is probably in part due to the greater ease of absorption in the several places. When the absorption is ra])id the bacteria can be taken into the blood, and thci-e be destroyed by the serum without time being given for their local action in producing necrosis of the tissue and chemical poisons. Grawitz has shown the importance of absorption in his work on the production of peritonitis in the dog. This animal possesses to a high degree immunity to the action of the sta})hylococcus. Large quan- tities of the organisms may be injected into the peritoneal cavity with- out any effect, provided the tissues are normal. If the po^^'er of al)sorp- tion be in any way interfered with, or if the serous surface be stripped off over a small area, general purulent peritonitis results. Halsted has shown that the same thing is true when, instead of a fluid culture, a piece of potato with a growth of the organism on its surface is placed in the cavity. In this case a fatal peritonitis is always produced. The potato has nothing to do with the result beyond affVjrding a suitable ])lace for the development of the organisms and allowing them to produce their chemical poisons. The jjotato without the organisms becomes rolled up in the omentum and encaj^sulated. If an emulsion of agar with the organisms growing in it be injected beneath the skin, it is more surely foli(>\\-ed l)y sujipuration than when the culture is injected in a fluid medium. One of the main elements seems to be the action of the sol- uble chemical poisons produced by the organisms. If the injection is made into a dense tissue, the organisms may find a suitable soil for their development, or they may create it by the production of necrosis in the surrounding tissue. The poison which they create may not only inhibit the local resistance of the tissue, but when it is gradually absorbed it may destroy the germicidal power of the entire blood-current. In any case it is of the utmost importance to oppose to the action of bacteria as normal tissues as possible. It is probable that a great deal of the INFLAMMA TION. 1 8 1 result of modern methods of surgical technique is due as much to the greater care bestowed upon wounds as to the care exercised in excluding bajteria. Differences in the virulence of the organisms play an imjiortant jiart in their effects on the tissues. The pus-organisms are not definite clicin- ical conijiounds, and they vary enormously in their virulence. This virulence is gradually lost in the cultures. It remains longer in the staphylococci than in the streptococci. A few generations of cultures may suffice to destroy the virulence of the streptococci completely. In the staphylococcus aureus we can to some extent estimate the degree of virulence by the intensity of the color which is produced. The source from wiiich the organisms are derived is also of importance, as is also the fact whether the organisms are injected alone or accompanied with toxic sulistanccs. The various accompanying toxic substances must play a great part in the purulent infections as they occur under natural con- ditions. In natui'al infection we have to do, not with pure cultures of the pyogenic cocci, but with organisms which have come from all sorts of sources and have been growing in various conditions, and which are frequently mixed with many kinds of bacteria. There is proof that under some of these conditions the infectious material may acquire a degree of virulence Avhich we ai'e not familiar with in artificial cultures. Bumm found that injection into the peritoneal cavity of a rabbit of a fraction of a drop of the fluid from a case of acute puerperal peritonitis produced acute peritonitis in the animal, whereas pure cultures of the same organism were nothing like so virulent. Fehleisen found that a pure culture of the staplti/Iococcus aureus to which he had added a little of the clear fluid from the inflammatory cedema of a spreading cellulitis was far more virulent than the ordinary culture. Any condition of the system which lowers its general resistance will increase the action of the pus-organisms. It has been found that sup- puration is more easily excited and is more intense in animals which have been rendered aiifemic. Even when local ansemia is produced by tying or constricting an artery, the suppuration following inoculation with the same amounts of tlie organisms is more severe on the anaemic side than on tiie normal. If the blood is rendered hydremic, the effects of inoculation ai'e increased.' Some of the infectious diseases render the tissues more liable to the effects of the pyogenic organisms. This has been shown in typhoid fever. An old focus of inflammation may become purulent when the resistance of tiie tissues is lowered by disease. Not oidy may the gen- eral resistance of th^ body be overcome, but the local resistance as \vell. Various local injuries of the tissjes have been produced, and then organ- isms injected into the circulation, and it has been shown that in many cases the organisms have settled in the injured tissues and have there produced a purulent inflammation. Sometimes the presence of other bacteria increases the action of the pus-organisms. Trombetta lias sliown that when cultures of the staphylococcus were mixed with tiie prodigiosus the effects were increased. The tubercle bacilli and the typhoid and other organisms when mixed with the staphylococci have ' Welch : Conditions underlying the infection of wounds. 182 SURGICAL PATHOLOGY. the same effect. The resistance of tlie tissues is undoubteclly lowered wlu'ii cliemical ])ro(lucts of tlie liactcria are introduced along- with tlicni. In any case it is probable tiiat tlie diminished resistance of the tissues is due to changes in the blood, and consists chiefly in destruction or diminu- tion of the germicidal power. The presence of such chemical products of bacteria may also prevent the establishment of leucocytosis. While it is ]ir()bal)le that in man tlie injection of even a large number of pus- organisms in tile normal blood would have little or no effect, the con- dition is different when the organisms enter into the blood after its germicidal jiower has been weakened by absorption of poisons from the local snpjiuration. Metastatic abscesses do not develop early in the course of a suppuration, but at a late period when the blood has been poisoned by absorption. They are not due alone to the organisms. Even dead organisms when injected into the tissues in sufficient quantities may excite suppuration, for the protoplasm of the dead bacteria is a powerful agent in attracting the leucocytes. In speaking of suppuration, so far, we have only considered it in relation to the bacteria. For all practical purposes that is the only way in which it need be considered. All of the sujipuratlve processes whicli we meet with in man are due to bacteria, and they may be obtained either in cultures made from the pus or on microscopic examination of the tissues. If the cultures made from an abscess are sterile, that is no proof that the suppuration was not produced by bacteria. The organisms may be dead or they may not grow on the medium which was used for culture. Other organisms than the bacteria may excite suppuration. It is known that some of the protozoa have this action. The amaha coll when it enters into the liver from the large intestine will produce abscesses, and it has been found to be the cause of abscess-formation in other places. Flexner has reported a case in whicli an abscess of the jaw was produced by this organism. It is certain that typical suppuration may be produced Ijy chemical substances, but abscesses so produced are not often met with. There has been a great deal of experimenting tlone on this question, and it may be regarded as established in the affirmative. Croton oil is one of the most certain substances to produce suppuration when injected into the tissues. In a series of experiments croton oil was enclosed in thin glass capsules which were pi'eviously thorougldy sterilized. These were placed beneath the skin of rabliits, and after several days, in every case after the wound was thoroughly healed, they were broken from without. In every case a typical focus of supjiuration was produced. It has long been known that when croton oil is rubbed into the skin a crop of small pustules will result. Turpentine and a few other substances will pro- duce supjiuration, but not so certainly as will croton oil. There is no reason why some of these substances may iKit do this. They are caustics, and when they come in contact \\ith the tissues they will produce necro- sis ; and they probably have in themselves, or they assist in forming in the tissues, substances which have the power of dissolving the necrotic tissue and the fibrin. Not only the purulent inflammations, Ijut inflammations of any sort, are affected by the condition of the liody, and especially by local or gen- eral pathological conditions of the cii\-iilation. For the preservation of IXFLAMMATWN. 183 the normal coiKlition of tlie tissues a normal circulation is necessary. The l^lootl must How tlirougii the tissues in the proper amount, with the proper pressure, ?ind the quality of the blood must not be altered. A change in any one of these conditions or all of them has an imjjortant influence in modifying the course of inflammation. We have already spoken somewhat of the influence of auiemia in modifying the purulent inflanunation. When the central artery of the ear of a rabbit is ligated, sufficient blood will enter the ear by the small arteries on the edge of the ear to preserve the integrity of the tissues. If, however, after liga- ting the central artery the ear be exposed to influences which in normal circidation would result only in a minor degree of inflammation, a much more severe tvpe, frequently ending in necrosis of the entire tissue, M'ill be produced. Samuel has sliown tliat tlie exposure of the ligated ear to water at a temperature which would only slightly atfect the part in a normal circulation will be followed by necrosis. In a more extensive series of experiments in parts subjected to various degrees of vascular disturbances he found that in aufemic parts all the phenomena of inflam- mation developed more slowly and ran their course in a much longer time. The congestion of the tissues comes on more slowly, is more extensive, and there is a tendency to coagulation of the blood in the dilated vessels, producing complete cessation of the circulation. The course of inflammation is also modified by active arterial hyper- semia. Danilewski first studied this by exposing both ears of a rabbit to the same injurious influence after section of the sympathetic on one side. He found there was a marked difference in the course of inflam- mation in the hyperiBinic ear as compared with the other, and the pro- cess took a more rapid and ran a more favorable course. He, however, made the mistake of regarding the ear not operated on as being in a normal condition. It is now known that after section of the sympathetic the hyperiemia of the ear on the side which is cut is acconqianied by anaemia of tlie ear on the uninjured side ; so that he really compared inflammation in a hyperKmic part witli inflanunation in a somewhat anaemic part. Samuel afterward studied tlie same subject more carefully, and found that in a hypercemic part a more severe type of inflannnation followed the same degree of injury and lasted longer. The exudation is more abundant, the swelling is greater, and all of the phenomena are more active. After the inflannnatory dilatation of the artery it does not so quickly return to the normal calibre in the hypcra?mic car as in the normal. Still more unfavorable are the conditions when inflammation takes place in a part in which there is chronic congestion. Here the quantity of the blood is increased, but, owing to the slowness of the circulation, the tissues are placed in an abncrmal condition. The part can, as in the anaemic ])art, preserve its integrity under tlie ordinary conditions of life, but slight influences will be more easily felt. The blood flows nwre slowly through the part, the blood-vessels themselves are dilated, and the tissue lives on a lower plane. Its reserve force, its capacity for rcjiair, is diminished. Not only will a slight cause produce a more severe type of inflammation, but tlie inflammation will run a mucii longer course and repair take place more slowly. Inflammation of this character is spoken of as hypostatic inflammation, and a good example 184 SURGICAL PATHOLOGY. of" it is seen in the inflammation of the posterior part of the hing which comes on in the conrse of various diseases when the patient iias lain for a long time on the hac'iv. The ordinary effects of liypostasis in such cases are increased l)y weakness of the circulation due to diminished force of the heart's contraction, and the blood itself is also altered. The cause of the inflammation in such cases is usually the stagnating secretion of the bronchi, in which infection may take place. Another example is seen in the inflammation of the leg in chi-onic jjassive congestion due to local or general impairment of the circulation. In this condition a slight blow or other form of injury whicli would not be felt, or only slightly, under normal conditions, will l)e followed by extensive inflammation, «hich may not heal until the part be placed in a condition more nearly approaching normal. This can be done by eleva- ting the leg and removing the influence of gravity. Not only will purulent inflammation take place more readily, but any inflannnation will run a more severe course in a person wlio is the sub- ject of general ana'mia. Other conditions — as diabetes, for instance — have a marked influence on inflammation. In diabetes the inflammation tends to assume a necrotic character. It is probable that in diabetes the germicidal powers of the blood-serum are greatly diminished. Infec- tion witli the pus-organisms takes place more readily and is more severe. The primary cause of inflannnation being injury to the tissue, however brought about, we can see that a tissue placed in an abnormal condition (•aunot so easily guard against an injury, and a slight cause will be fol- lowed by a greater effect. The inflammation will persist until the integ- rity of the tissue is restored, and this will take longer when the condi- tions for the nntrition of the tissues are not so favorable. Sometimes a tendency to certain sorts of inflannnation seems to be inherited. In some persons, even when the circulation and nutrition seem to be pei- fectly normal, inflannnation is more easily excited in certain organs and takes a more severe course. Thus an individual may be predis- l)osed to inflammation of the air-passages and other parts of the body. In this case it is not the inflammation itself which is inlierited, but a weakness or lack of resistance of the Ixidy. AVhat this is we are unal)le to define. It may be, as Cohnheim suggests, an abnormal condition of the blood-vessels of the part. It seems in many cases to be local and not general. In some cases there appears to be a general weakness of the tissues inherited. There may be an inherited lack of resistance to certain causes of inflammation or to inflannnation generally. Individ- uals with an inherited tendency to tuljereulosis frequently show a general lack of resistance to all sorts of inflammatory causes. Rejieated attacks of inflammation in the same part render it more liable to inflammation. This is due to an abnormal condition of the part caused by the repeated attacks of inflammation. At each attack of inflammation the tissue may not be completely restored, and finally an abnormal tissue, one of lower resistance, is established. The tissue is then jjlaced in the same condition as when subject to antemia or any other disturbing influence. It can only preserve its normal condition under ordinary circumstances. The tissues are more vulnerable, and a cause which would not be felt in a normal tissue may produce a degree of injury in this ^vllicll cannot be overcome without inflammation. IXFLA .V.V.I TIOX. 185 It is not necessary to consider at oreat icnsith the diifercnces between acute and clu'onic intlamnuitiun. The phenomena of inflammation vary in duration and last until the tissue is brought to a normal state. In general, the difference is due to the length of time that the cause of inflam- mation continues. A sudden injury of the tissue, in which the cause is rcmoyed as soon as tlic injury is effected, is followed by active inflam- matiiry phenomena, wliicli will also sul)sidc when the cause — that is, the injury which has been produced on the tissues — is removed. In some cases" the injury may take place more slowly, and the injurious agent, whatever its character, may act continously, and the phenomena of inflam- mation develop more slowly and continue for a longer time. In those cases we have the process of repair, the attempt o( the tissues to return to a normal condition, going on at the same time that the injurious cause is still acting, and the phenomena wliich we are accustomed to regard as typical of inflammation — i. e. heat, redness, swelling, and pain — develop so slowly or mav be so slight as to escape our attention entirely. These chronic inflanmiations are frequently due to bacteria, which may extend their action not only to the tissues into which they first enter, but may continously affect the new tissue wiiich is produced in the repair. Another variety of inflannnation is the so-called tro])liic inflammation suj>})osed to be due to trophic disturbances. It is assumed by those believing in this that there is a direct nervous influence acting on the nutrition of the tissues, independent of the influence of the vasomotor ncryes. The nutrition of each cell is sup])osed to be directly influenced l)v the nervous system, and the nerves governing this nutrition are spoken of as trophic nerves. Physiologists in general and pathologists do not believe much in this, and the arguments advanced in favor of the view have generally come from clinicians. As an example of such so-called trophic inflammations we may cite the inflannnation of the cornea which follows section of the trigeminus. INIagcndie first observed that after section of this nerve inflannnation of the cornea, with ulceration and jical rcoeneration of tissue differs materiallv from the ph\siolo"ical. It is frequently not confined to a simple restoration of the tissue lost, but the amount jJi'oduced widely exceeds this. In inflammation of the skin there is often an excessive epithelial growth, and scars may be ]irodaced from the connective-tissue regeneration which at first pro- ject beyond the level of the skin and appear as red elevations. In the inflammatory regeneration of bone more callus is produced than is neces- siiry for the supply of the portions of bone which have been lost. The power of regeneration is different not only in the different tissues of the body, but also in different animals. The higher the organization and the greater the differentiation of tissue, the less is the power of regen- eration, which is greater the younger the animal and tlie nearer it comes to an emljryt)nic ccmdition. In some of the lower animals, as the Crus- tacea, an entire part may be removed, and it may be completely re-formed. In the frog the power of regeneration is much more marked in the tad- pole than in the adult. When the tail of the tadjiole is removed an entire new production of tissue will take place. The different tissues also show different powers of regeneration after loss. The more C(im- pletely diflerentiated the tissue and the farther it is removed from an em- bryonic condition, the less is the power of regeneration. In some tissues it is probable that there is no new formation of cells, and only the portions of the cells which have l)e(>n used u]) by tlie physiological ])ro- cesses will be restored. After injury in the central nervous svstem there is no new formation of nerve-cells. The same thing is true to a more limited extent in the striated muscles. Any loss in these tissues is sup- plied by a gro^vth of connective-tissue elements. In certain of the glandular organs the power of regeneration is greatly limited. The new formaticjn of connective tissue in inflammation does not always take the form of a pure regeneration. In the place of the nor- mal connective tissue a somewhat different tissue is formed, which is designated as cicatricial tissue. This cicatricial tissue differs from the normal connective tissue in the paucity of its cells and blood-vessels and in the density of .its intercellular substance (Fig. 7). The charac- ter of the intercellular substance seems to be similar in general to white fibrous tissue, but its exact character has never been fully made out. The fihrillie are more firmly interwoven together, and cannot be sepa- rated so easily as they can in white fibrous tissue. In some inflammations, especially in the more chronic, the new formation of connective tissue may so greatly exceed the necessary amount to su])ply the defect, and form so ])rominent a part of the inflammatory process, that inflamma- tions of this character have received a different name and are known as Vol. I.— 13 194 SURGICAL PATHOLOGY. productive inflammations. The excessive amount of connective tissue wliich is formed may often exert a deleterious influence ou the future life and the functions of the inflamed part. In order tliat any new formation of tissue may take place new blood- vessels are necessary. TJie okl l)lood-vessels of the part wiiere tiie new tissue is to be formed have been destroyed to a great extent, and multi- plication of cells will not take place except under tlic Ijest conditions of nutrition. If I'cgeneration to any extent takes place in non-vascular parts, these become vascular. In any extensive injury of the cornea new blood-vessels grow into the tissue from the sclera in a comparatively short time. In man ulceration of the cornea is always followed by a vascularization of the portion of the cornea between the ulcer and the sclera. These new blood-vessels are formed from the old. The for- mation takes place by direct outgrowth from the old vessels. In this formation both tiie endothelium of the vessels and the connective-tissue cells in the neighborhood of the vessels take part. The process is the same as in the new formation of blood-vessels in the embryo. It can be well studied in the regeneration of tissue which takes place after cut- ting otf the end of a tadpole's tail. The first thing which seems to take place is an enlargement of the endothelial cells of tiie vessels. These become large, filled with protoplasm, and long projections extend into the neighl)oring tissue. The nucleus of the cells divides, and nuclei pass up into the projection in very nuich the same way as in the regen- eration of the cells of the cornea. Tlie connective-tissue cells in the vicinity enlarge, and arrange themselves cither alongside of the projec- tion from the endothelium or as a continuation of this. In this way pointed processes of some length are formed. These meet with similar processes from the same vessel or from neighboring vessels, and in this way loops are formed which are at first solid. These solid processes are gradually iiollowed out and l)ccome continuous with the lumen of the vessel. In some cases the lumen of the vessel gradually follows the formation of the sprout. In other cases loops are formed before the communication with the lumen of the vessel takes place. In this new formation of blood-vessels there must be a process somewhat similar to chemotaxis. In the cornea the blood-vessels are always formed from that portion of the sclera which is nearest the ulcer, and they show no tendency at all to extend anywhere but into the cornea. In the fonna- tion of the loops there must be also a mutual attraction for the cells, because the meeting of the pointed process from the same or from neighboring vessels, and the resulting formation of loops, cannot be regarded as a matter of chance. This new formation of vessels always proceeds from the capillaries, and the newly-formed vessels are always of this character. They function as the old vessels. When the inflam- mation continues emigration takes place from them as readily as, or more readily than, from the old vessels. They are more easily dilated, and when dilated the dilatation frequently persists for some time. Later, these vessels may become differentiated into Iroth arteries and veins, but the manner in which this differentiation is ])roduced has not been fully made out. Other modes of new formation of the vessels have Ijcen described. According to some authors, the cells in the inflamed part, the cells of the tissue, may collect together in rows and may become REPAIR AND REGENERATION. 195 changed into enclothelial cells, and a communication be established be- tween the old vessel and the newly-formed ; or large cells of the tissue may become holIo\\cd out and "in this way new cells are formed. Fig. 9. :9, ^& ^>,^;^,g ^'Ojo.: i:.-v.-.,--u. ';^/^r£.r^..:-'D. Hi^iiiiSi a Section through a portion of a suture which had remained in the tissue eleven months. The suture first becomes infiltrated with leucocytes, and the formation of connective tissue takes place as in Fig. 8. The section represents only a fragment of the suture : a, a, silk flbrillse surrounded by dense connective tissue; 6, 6, giant-cells enclosing iibrillae. Strieker believes tliat not only are new vessels formed from the cells in this way, but that there may be a new formation of red corpuscles in the.se vascular cells in the same way as in the embryo. The essential cause of the new formation of blood-vessels and the influence which leads to it are obscure. We know only, in general, that they are formed in accordance with the law of nutrition — that where more blood is required for a part it will be given, either by a dilatation of the old vessels or, if this be hot sufficient, by a new formation of vessels. There has been considerable controversy with regard to the participa- tion of the leucocytes in the new formation of tissue. Cohnheim be- lieved that not only were all the cells found in an inflamed part leuco- cytes, but that any new formation of tissue takes place from leucocytes. He was led to this belief by a number of experiments. He showed that there could be a new formation of tissue in parts in which all the living cells were destroyed by boiling and which were afterward placed in the peritoneal cavity of animals. The tissues became filled with 196 SURGICAL PATHOLOGY. leucocytes which ■wuiidcn'd into tiicm, and, as a iiewly-foriuecl connec- tive tissue witli blotxl-vessels was afterward found in the tissue, he believed that this new formation must take place from leucocytes. Some experiments which Ziegler made on this siihject seemed to \w at first con- clusive. He enclosed two thin jtlatcs of li'lass with a ca])illary space be- tween them in the siibcntancous tissue or in the peritoneum of an animal, and found that a thin laniclla of connective tissue was formed l)etw('cn the plates (Fig. 9). The first thing seen in such conditions is a filling up of the spaces between the plates with leucocytes and fibrin. After- ward large cells with a round nucleus and a large amount of protoplasm appeared, and from these large cells the formation of connective tissue takes place, either by a diflt'erentiation of the body of the cell into fibrous tissue or by a sort of secretion from the cell. The exact method in which this formation takes place has not been fully made out. Ziegler supposed that these large cells were produced directly from the leuco- cytes, but a repetition of his work by other observers has shown that they, like the leucocytes, wandered into the glass cell from without. In any ease the new foriuation of tissue seems to take place from the large protoplasmic epithelioid cells (Fig. 8). The leucocytes probably take a part in the process, but only a passive one. Many of these large cells are phagocytic in character, and it is probable that the leuco- cytes play a distinct part in furnishing them nutrition, being taken up and devoured by these large connective-tissue cells. Sometimes there is in this way new formation of cells from the old, which simply supplies the tissue which has been lost. In this new for- mation of cells all of the tissues can take part. It is proliable that the cells most actively concerned in it are the cells of the small blood-ves- sels. In other cases there is not an immediate formation of cells from the cells of the old tissue, but tliere are intermediate steps. The new tissue is not formed directly from the old, Init tliere is a formation of granula- tion tissue first. In the cornea, for instance, if the loss of substance is extremely small, it may be supplied by a simple new formation of cells ; if larger, there will be a ])receding formation of granulation tissue. Some of the granulation cells will afterward ditferentiate themselves into tissue-forming cells. The tissue which is formed in this way from the granulation tissue is never so perfect as that formed directly. It always approaches the character of cicatricial tissue. The ])rocess of regeneration of tissue can also be studied on the ulcer, and in the ulcer we can also study the local conditions which may interfere with this regeneration. In the ulcer the regeneration of tissue nuist take place in two directions. There is not only a new formation of necessary tissue from the connective tissue, but a new f\)rniatioii of epithelium must also take place. Until the surface is covered over Avith epithelium it nuist be constantly subjected to various trau- matic influences wliich will keep up the inflammation. If the ulcer is small and the local conditions favorable, the epithelium will grow in from the edges, cover over the surface, and the inflammation will sul)side. This new formation of epithelium takes place solely from the surround- ing epithelium. It has been supposed by many that a new formation of epithelium may take place from the granulating surface of the ulcer. The proof of this was supposed to be shown in the fact that the growth IXFLAMMATION. 197 of cpitlielium does not always prow't'd oveiily from the edges, but small islands of epitlielliim are sometimes formed in the middle of the uleer, and from these a growth extends upward to the edges. These small islands which are formed in the centre of an ulcer do not represent a new formation of epithelium from the edges of the ulcer, but are the remains of epithelial tissues, such as sweat-glands or the sebaceous glands of the skin, wliich were not entirely destroyed by the injury whicii produced the ulcer. An ulcer never heals by a simple process of tissue-formation, such as is seen in the cornea, but there is always a formation of granulation tissue, and from this the regeneration proceeds, leading to the production of cicatricial tissue. The amount of cicatri- cial tissue varies with the extent and duration of the ulcer. It is exceedingly dense, firm, and contains few bhiod-vessels. It may extend into the surrounding tissues for a considerable distance beyond the actual seat of the ulcer. In the most common seat of ulceration, the anterior surface of the lower leg and ankle, there are numerous local conditions wiiich interfere with the process of healing. In the first place, the ulceration is constantly repeated at the same spot. The tissue is not normal, it has not the normal vascular supply, and it reacts to injuries more easily. Not only is there this abnormal tissue with weak vascular- ization, but the ulcers usually arise in persons who have a local passive congestion. In the process of healing the new formation of blood-ves- .sels does not so readily take place. As we have seen, in spite of the apparent vascularization of the tissue of the nicer, it is really poorer in blood-vessels. Frequently, healing will not take place until the dense cicatricial tissue resulting from a series of old ulcers is removed in toto, or until incisions be made through it so as to allow vascularization to take place from the deeper and more healthy tissues beneath it. The Effect of Inflammation on the Body as a Whole. The objection was early made to the theor}' of inflammation of Cohnheim that all of the cells found in the inflamed part could not come from the blood, because there were not enough cells in the blood to produce these. In an acute fibrinous pneumonia one entire lung and a portion of the other may lie so filled uj) with tJie inflanunatory exudation as to resemble a .solid mass and to sink in water. The consolidation of the lung is due in large part to an accumulation of leucocytes, and in a case of advanced pneumonia the number of leucocytes in the lung could not be estimated by numbers, but by pounds. The same thing is true in the large puru- lent exudation which we find in empyema or in peritonitis. There are at no time enough leucocytes in the blood to form such masses even if all of them could be tpken u]). It was supposed also that after the leucocytes had emigrated from the vessels they multiplied, and that many of them could he newly formed from those whicli at first emigrated. In speaking of this Cohnheim says that in general we can form little idea of the number of leucocytes in the blood from microscopic observation, because large luunbers of leucocytes break up and disajipear the moment the blood is taken on the slide for examina- tion. He also suggests that there may be a new formation of leuco- cytes in the blood, and an increase in their number due to this. He 198 SURGICAL PATHOLOGY. called attention to the enlargement of the lymphatic glands and spleen frecjuently seen in acute inflammation, and supposes that this may in some way stand in relation to the number of leucocytes found in the exudation. Cohnheini, however, made no estimate of the supposed increased number of leucocytes in the blood. As early as 1842, Gul- liver called attention to the similarity between the pus-eells and the leucocytes, and thought that in inflammation the white corpuscles of the blood were increased ; and he instances a case in which, in a stallion which had a large abscess, the white corpuscles of the blood were almost as numerous as the red. Virchow also, in his study of the blood in Icu- cicmia, recognized the fixct that in most acute inflannnatioiis, especially if they were at all extensiv'e, the white corpuscles of the blood increased in number. He supposes that this is due to the fact that the lymph- glands and other blood-forming organs undergo a stimulation which excites them to an increased activity. We know now that in any inflam- mation, and especially in an infectious inflammation characterized by extensive exudation and emigration, the white corjiuscles arc increased. It is only recently, when the study of the corpuscular elements of the blood has received great attention, that the extent and importance of this leueocytosis have been recognized. The leucocytosis keeps almost an exact pace with the fever and the extent of the exudation. In croupous jineu- monia we liave the greatest extent of leucocytosis, and the number of leucocytes in the blood may be double or treble that of normal. The leucocytes which are found in increased number are exclusively of the polynuclear variety. The feet that in inflammations uncomplicated with hyperplasia of the lymphatic glands there is no increase in the mono- nuclear leucocytes speaks against the emigration of these and their taking part in the exudation. The uKinonuclear leucocytes are increased in tyjihoid fever and in other processes connected with a lymphatic hyper- ])lasia. The recognition of a ]>olynui-lear leucocytosis in the blood is frequently of great importance in determining the character and extent of inflammation. Wc find other changes in the blood in addition to the leucocytosis, but they jirobably depend in large measure ujion this. If the inflammation is suiticiently extensive and lasts long enough to inter- fere M'ith the general nutrition of the liody, a diminution in the number of red corpuscles may take ])lace. In acute inflammations, especially when connected with an extensive leucocytosis, there is an increase in the fibrin of the blood. This has long been known, and M'as formerly used as a diagnostic means for recognizing the extent and character of an inflammation. Although the fibrin is increased in the Idood in inflammation, it coagulates more slowly. Tliis slow coagulation of the blood allows the red corpuscles to sink from the surface of the blood before coagulation takes place. As a result of this, on the surface of the clot there is a layer of coagulation which has a buify or straw color. This is known as the buify coat of the blood, and in the old days of bloodletting a great deal of imjiortance was attached to it. Fever is a frequent accompaniment of inflammation. FEVER. 199 II. FEVER. Fever can well be considered in connection witii inflammation, for it is an almost constant accom])animeut of it, and the etfect on the general organism of a local inflammation is shown first of all in the production of fever. In fever the normal temperature of the body is increased. Usually this increased temperature is accompanied by other abnormal conditions, but these are not necessary to the condition. Observations on normal individuals sIkjw that the temperature of the body, in spite of variation in the surroiniding temperature and in spite of all sorts of changes in the external conditions of life, has a medium value of 37.2° to 37.4° C. The absolute variations in the course of the day may be from 1° to 2.5° C. The body is able to maintain such a temperature, far above tliat of the surrounding medium, only by the production of heat by means of chemical processes taking ]ih\ce in the tissues. The produc- tion of heat is oftset by a discharge of heat, which takes place by means of the skin, the lungs, and the various excreta of the body. Ordinarily, the production of heat and the discharge of heat are so evenly balanced that the temperature of the body remains the same in all conditions. The Production of Heat. The various chemical processes which take place in the body are accompanied by the production of heat. At every muscular contraction, in all the processes of glandular secretion, heat is produced. Of all the tissues of the body, the muscles, not only from their bulk, forming as they do a large part of the whole frame, but also from the character of their metabolism, must be regarded as the ciiief source of heat. Not only is heat produced in the contractions of the muscles, but during their quiescent period metabolic changes are taking place in them by which heat is produced. Next in importance to the muscles are the various secreting glands. Tlie secreting elements of the glands in the periods of secretion, and pi'obably in the cpiiescent period, are in a state of meta- bolic activity which must give rise to heat. In the case of the salivary gland the temperature of the saliva secreted during stimulation of the chorda tympani is 1° to 1.5° higher than that of the blood in the carotid artery. The blood in the hepatic vein is the warmest in the body. In the dog a temperature of 40.73° has been observed in the hepatic vein, while tiiat of the vena cava was 38.35° and tliat of the right lieart 37.7°. The brain, too, may be regarded as a source of heat, since its temjierature is higher than that of the arterial blood with which it is supplied. The other tissues of the body also serve as sources of heat, but the part they play is insignificant as compared with the muscles and glands. The increase of temperatui-e of the bfxly in fever may I)e due to either of two conditions : There may be increased production of heat, the discharge being the same or even increased, or, the production being the same, the discharge of heat may be reduced. One of the best known of the theories of fever was that advocated by Traube. Accord- ing to his views, there was no increased production of heat, but the increased temperature was due to a decrease in the discharge of heat. The discharge of heat lie supposed to be least in the earlier period of 200 SURGICAL PATHOLOGY. fevor and increased in tiic (icf'crv<'8eence. A great deal of work lias been done to determine wlietlier there is increase of heat in fever, and its degree. Various methoils have been used to determine this. The heat being the residt of eheniieal elianges in the body, it was sought to deter- mine if these chemical ciianges were more active in fever. It is known tiiat most fever patients lose weight and that there is increased consumji- tion of tissue. Tiic urea is increased, and for a long time it was believed that the increased excretion of urea att'ordcd satisfactory evidence of increased oxidation and incrmscd production of heat. Of late years investigations have been made upon the consumption of oxygen and the ])roduction of carbonic acid in fever, and it is found that there is an increase in the amount of oxygen consumed and in the carbonic acid given off. In the Ix'ginning of fever, when the temperature is con- .stantly rising, both of these processes are most active ; during the stage of defervescence the consumption of oxygen may fall below the normal. It has been claimed that the increased oxidation was not the cause of the fever, but simply resulted from the increased temperature of the body. Although it is true that there is an increase of oxidation in increased temperature, the elevation of the temperature 1° C. would only increase the oxidation 3.3 per cent., while in fever the oxidation may be increased l."J-15 per cent. Although it has been generally accepted that in fever there is increased oxidation of tissues and increased production of heat, this alone would not be sufficient to explain the high tem])crature. The increase in heat-production in fever is far less than would take ])lace in an individual making active muscular movements in a cold environment. In health the increased heat-production is met by a correspontling dis- charge of heat, so that it has no effect on the body temperature. The loss of heat in fever has been investigated by direct calorimetry. The discharge of heat is least during the initial stage of fever, and increases during the stage of defervescence. During the hot stage the discharge of heat exceeds the normal, but usually, on account of the dryness of the skin, is not so great as might be inferred from placing the hand on the surface. In the febrile chill not only is the discharge of heat by the contraction of the vessels of the skin reduced to a minimum, but heat- production is excited to the utmost. As the result of the work of most investigators it may be said that in fever both heat-jjroduction and heat- discharge are increased. Recently, Rosenthal, %\hi) has investigated this question by means of a specially constructed air-calorimeter, using animals in whom fever was produced by the injection of various substances into the circulation, has returned to the view of Traube. He finds that in the initial stage of fever and in the stage of gradual increase of temperature the discharge of heat is diminished and there is no increased production of heat. When the fever has lasted a considerable time there is a return to the normal discharge of heat. The diminution in the discharge of heat he thiidis is due to sudden changes in the circulation of the skin brought about by vasomotor influences. In the stage of defervescence the dis- charge of heat is greatly increased, and al)out corresponds to the decrease in the temperature. If the regulatory mechanism were normal, the discharge of heat in fever would be increased in proportion to the increased production and the FEVER. 201 temperature would he unaltered. The regulating mechanism, although jjrofoiindly disturhcd, is not jjaralyzed in fever. External cold in f'e\er to some extent stimulates the heat-produetiun, but not nearly to the same extent as in health. A person in te\-er is not able to maintain his tem- perature under the influence of heat and cold to the same extent as a person in health. It is not merely, as some have sujiposed, that the regulatory mechanism is set for a higher degree (jf heat, but that it is disturbed. In both health and fever tlie regulatory mechanism is under the control of nervous inHueni'c. This acts through the vasomotor nerves jiresiding over the sujjerticial parts of the body, and Ijy producing variations in the calibre of the cutaneous vessels controls in great meas- ure the discharge of heat. The jiersjjiration which plays so great a part in the discharge of heat by evaporation is also under the influence of the nervous system. Heat-regulation is effected not only by means of varia- tions in heat-discharge, but heat-production is also under the influence of the nervous system. In a cold atmosi)here more heat is produced, and in a warm less heat, provided the external temperature is not so high or so low as to make it impossible to preserve the body tempera- ture. To regulate the temperature simply by the discharge of heat would be like regulating the temperature of a room by opening the doors and windows and paying no attention to the furnace. There is every reason to believe that nervous impulses control chemical changes which result in the production of heat independently of visible altera- tions of the tissues, so that heat-production is in considerable part under the control of the nervous system. The nerves controlling the produc- tion of heat are known as thermic nerves, and they ai'c controlled by cen- tres in the brain. The chief of these centres is in the nucleus caudatus, and if this centre is stimulated by puncture with a needle or by electri- cal stimulation, fever, often reaching several degrees above the normal, will result. A number of cases have been collected in which fever re- sulted in man from injuries involving these centres in the brain. It is very probaljle that fever may lie the result of the stimulation of these centres in the brain by pyrogenic substances in the blood. Opposed to this is the hiemic thecny, which assumes that the increased temperature is due to the direct action on the tissues of pyrogenic substances con- tained in the blood. After puncture or stimulation of the caudate nucleus of animals they present all the phenomena of fever. There is increased heat-production, with increased consumption of oxygen, and the heat-regulaticin is also interfered with. Liebermeister regarded all tlie phenomena of fever, the changes in the pulse, respiration, etc., as due simply to the eftect of the increased tem- perature. He urged that the weakness of the heart, which is undoubt- edly one of the most -serious dangers in fever, was due to the increased tem])erature, which caused parenchymatous and fatty degeneration of the cardiac muscle. According to his views, the one great indication in treatment was to lower the temperature of the body. Of late there has l)een a reaction against these \iews of Liebermeister, which reaction has in part been brought about by the fact that antipyretic drugs may reduce the temperature, but may not affect the other phenomena of" fever. Some authors have gone to the extent of not only denying that there is danger in temperatures whidi do not exceed a very high point, 202 SURGICAL PATHOLOGY. hut of" stating that the elevation of temperature in itself may be a benef- ieent provision of nature in warding off the effects of disease. It is obvious that the effects of high temperature cannot be studied in the fevers of man nor in the artificial fevers produced by the injection of various substances into the blood. The effects of the temperature must be separated from the effects produced on the tissues by the agents wiiich cause the increase in temperature. The eflects of temperature alone have been studied by subjecting animals to a high temj)erature. Some of the earlier experiments have seemed to bear out Liebermcister's view of fever. It was found that animals whose temperatures were artificially raised to 40.-5° or 41.7° C showed evidences of illness. All experi- menters agree that a mammalian animal dies when its temperature is raised to 44° or 45° C. Death is preceded by convulsions, and rigor mortis develops almost immediately after death. Death in these cases has been attributed to heart-paralysis due to lieat-rigor, but it is known that heat-rigor does not take place at such tenijieratures. In all of the cases in Mhich death took place after keeping the animal for some time at a temperature of 40.5°-41° fatty degeneration of the heart was found. The most complete set of experiments on the influence of high tem- perature alone was made by Welch at the Johns Hopkins Hospital. In all the jirevious experiments the animals were kejit in small, dark, badly- ventilated boxes, and the influence of the high temperature was assisted by the bad surroundings of the animals. In Welch's experiments the animals were kept in a large box partially closetl at tiie top by a blanket. The box was surrounded, except at the top, by a layer of water. The animals were supplied with an abundance of green food and water, which they took greedily. He succeeded in keeping two large black rabbits for two weeks with an average rectal temperature in one of 41.4° C. and in the other 41.8°. The animals lost weight while in the box in spite of their abundant food, but otiicrwise seemed perfectly well. He found considerable differences in different individuals in their capacity of withstanding high temperatures, and thinks, in gen- eral, that black rabbits are more resistant than white. In all cases, after keeping the animals for some time, extensive fatty degeneration of the heart, liver, and kidneys was found. He is not inclined to attach so much clinical imi)ortance to the fatty degeneration of the heart as some have done. In a series of experiments which he made on animals in whom fsitty degeneration of the heart had been produced by heat he found that the blood-jjressure was kej)t at the usual height, and the heart reacted to nervous stimulation in the usual way. In one case he observed tlie contraction under the microscope of some fibres of heart-muscle in which the fatty degeneration was so advanced that no striation could be seen. He thinks from this that the effect of fever on blood-pressure is not due to increased temperature alone, but to other factors. Animals which had been rendered ana?mic by bleeding were more affected by increased temperature than normal animals. Animals with an artificially increased temperature had their cajiacity for temper- ature regulation disturbed, so that they were more suscej)tilile to the effects of heat and cold than normal animals. The various fevers differ materially in the eflects jiroduced. In rclajjsing fever temperatures can be withstood which in typhoid fever or pneumonia would be fatal. FEVER. 203 In fever the frequency of respiration is increased. This has been atti'ibuted to tlie direct etJ'ect of tlie heated l)lood ii])on tlie respiratory centres in the meduHa. The experiments of Goklstein made in Fick's laboratiny are able of causing it, and to which the name pyrogcuic has been given. A great deal of work has lieen done of late in the investigation of these substances. Most of the normal fer- ments of the body, particularly fibrin-ferment, may give rise to fever when injected into the blood. Of great interest in this connection is the aseptic fever which was described by Volkmann. It follows injuries to the tissue in which there is no ])ossible infection. Nothing shows more clearly the line which should l>e drawn between the high temperature and the other phenomena of fever. Tiiis aseptic fever has no prognostic importance. In a case of subcutaneous fracture, with extravasation of blood into the tissues, temperatures of 40° C. or over may be seen without any other phenomena of fever save slightly increased pulse and resjii- ration. Absorption of perfectly ase|)tic products of tissue-necrosis will give 204 SURGICAL PATHOLOGY. rise to fever. Gaiifrolplie and C'onmiont have sliown that the injection of the fjerm-free tissue-jiiiee from j^anijrenous tissues is in a hiu;h dcg'ree pyrojrenic. They also prixhiced net^-osis in the testicle by means of a IJiiatMre, and fonnd tliat the fluid of tlie necrotic tissue produced fever. Tile jMiwer of filiiiu-fcrnient in producing fever is well known. Any sulistance which will give rise to it acts as a pyrogenic agent. Thus water injected into the blood will give rise to fever. It lias been clainicd that most of the substances which produce fever act by producing coag- ulation in the capillaries and small blood-vessels, and so giving rise to tibrin-ferment. Hildenbrandt found that after the injection of various ferments into the blood there was extensive thrombosis of the small vessels in the liver, intestine, lungs, and kidney. The presence of fibrin- ferment cannot be regarded as the sole cause of the fever, for the highest temperatures are not found in the diseases in which the greatest quantity of ferment is found in the blood, and fever may be present in cases in which this ferment is entirely absent. It is questionable whether fever may be the result of irritation of the peripheral nerves. The cases usually cited as e.\am|)les of this are the fever of children during teething and the fever which sometimes follows the introduction of a catheter. It does not seem reasonable that all eases of catheterization fever should be ascribed to the introduction of bacteria or to injury of the urethra. There are numbers of eases in which the careful introduction of an aseptic catheter has been followed by a chill and fever lasting a short time. The chill may follow so shortly after the introduction of the catheter that time is not given for the in- crease of Ijacteria should any have been brought with it, and it is not probable that the pyrogenic substances produced by bacteria elsew^here are on the catheter. Nor is time given for the development of sufficient iuHanunation to cause fever even if an injury was produced by the catheter. In many cases a temporary increased tenqierature is the only phenomenon. The case is different when fever follows the introduction of a catheter into an inflamed urethra or bladder. In regard to the question of pro- duction of fever from peripheral irritation, a strong argument against it is that it is only in certain ])arts of the body that such irritation is followed by fever. No irritation of the skin in general which is not followed by inflammation will produce fever. In the inflamed bladder or urethra the pvrogenic material is already jircsent, and sufficient injury may lie pro- duced to cause its absorption. Most of the chemical products of bacteria are pyrogenic. These may be absorbed into the circulation from a local lesion of some sort, or they may be absorbed from the alimentary canal without any local lesions being present. There is no doui)t that abnormal processes of fermentation in the alimentary canal may ])roduce chemical substances which when al)sorl)ed may give rise to increased temperature and the other phenomena of fever. It is easy to see why inflammation should be so constantly accom- panied by fever. In the inflammatory exudation, whether of an aseptic eratures. A\'hile there were apparently no symptoms produced in the heated animals, poisoning rapidly developed when they were exposed to ordinary temperatures. He further calls attention to the fact that all infectious diseases accompanied by fever have a tendency to recover, while the afebrile infectious diseases, such as leprosy and rabies, have no tendency to recover. From all we have seen of inflammation it seems evident that its ])lienomena are essentially conservative in their action on the organism, and it cannot be assumed that so marked a phenomena as the lever should have the opposite tendency.' m. THROMBOSIS AND EMBOLISM. Thrombosis. Thrombosls is the coagulation of the blood in the vessels during life. When blood is taken from the vessels during life, after standing some time it undergoes coagulation, changing from a fluid to a solid form, and the vessel containing it can be inverted without spilling tlu' I'ontents. We owe the most of our knowledge of the process of coagulation and the factors concerned in it to the work of Alex. Schmidt and his pupils. Schmidt was able to separate from the blood two substances, each with definite chemical ])roperties, to one of which he gave the name of paraglobulin and ti> the other the name of filn-inogcn. The fibrin of the blood does not exist pre-formed in the blood, but is due to ' In these remarks on fever extensive use has been made of the Cartwright Lectures on fever by Prof. W. H. Welch. 20(5 SURGICAL rATHOLOGY. the union of thoso two sulistanccs, tlie union licinfj; iironfjlit about l)y tiie presence of a thinl .suii.stanee ^\•llieil lias all the characters of a fei'nient, and which is called fibrin-ferment. This ferment is destroyed or ren- dered inoperative at the death-jjoint of protoplasm and of the other fer- ment-substances of the body ; that is, at about 58° C. If the blood be heated to 58° C. before any coagulation has taken place, the power of undergoing' coagulati()n is lost. The ferment appears to be principally contained in the white corpuscles and is set free by their disintegration. Other tissues of the body may contain this substance, or substances M'hich are analogous to it and which act in the same way. A proteid substance may be obtained from the thymus gland whic^li when injected into the circulation pi-oduces extensive coagulation in all the vessels and leads to the death of the animal. The disintegration of other tissues of the body also produces fibrin-ferment. In necrosis, sul)stances are pro- duced which cause coagulation in the blood-serum which comes in contact with the necrotic tissue. A new theory of coagulation has been advanced by Arthur and Pages. These observers found that if a certain proi>ortion of oxalate ' &^ of potash be added to freshly-drawn blood, it loses its jiower of coagula- tion. They attribute the action of the oxalate to the precipitation from the blood of the soluble lime-salts which it contains. If a solution of chloride of lime be added to the blood containing the oxalate, coagula- tion will take place. No matter how long the oxalatcd blood may be kept, it will remain fluid, and coagulation will take ])lace as soon as the lime-salts are driven from their connection with the oxalate and again set free in the fluid. The fibrin-ferment only acts on the filirinogen, converting it into fibrin when lime is present. In coagulation the fibrinogen undergoes a chemical change by M'hich it is converted into fibrin, the fibrin being a union of lime-salts and albumin. The coagulation of the blood in the vessels during life is jirevcnted by some action exerted on the blood by the living endothelium of the blood-vessels. The blood contains the necessary element for coagula- tion, and a certain amount of fibrin-ferment must be constantly pro- duced by the disintegration of leucocytes and other cells, which to some extent is always going on. In inflammatory exudations and in the necrosis of the tissues fibrin-ferment is certain!}- present, and being soluljle it must enter into the circulation. If a large vein of an animal be carefully ligated and removed from the body while filled with blood, coagulation of the blood contained in this receptacle does not take place for a long time, and when it does the clot is always thinner than when formed under ordinary circumstances. The serous tissues act in the same way in preventing coagulation. If small vessels are included between doul^le ligatures, care being taken to pre\'ent any injury to the vessel by the ligature, tlie blood in the vessels will not coagulate. Stag- nation of the blood in the absence of other factors will not produce coagidation in the vessels, but it will fiivor it. If the wall of the blood- vessel is injured in any way, thrombi will be formed on the injured sur- face. It is not known to what this action of the living endothelium in preventing coagulation of the lilood is due. It is not due to the smooth- ness of the surface alone, for N'irciiow has shown that thrombi will foi'm around globules of quicksilver when they are brought into the THROMBOSIS AND EMBOLISM. 207 circulation. It is probable that the prevention of coagulation is a property of the living endothelial cells. The endothelial cells do not simply provide a physical lining to the vessels, but have as definite prop- erties as gland-cells, and they may produce substances which oppose the action of the fibrin-ferment. Coagulation of the lilood takes place in the vessels a few hours after death. Certain conditions favor or oppose the post-mortem coagu- lation. An excess of carbonic acid in the blood retards the coagula- tion, and in death after sufibcation the blood is usually found fiuid. The l)]ood is fluid, or clots feebly, after death from certain poisons and from a number of infectious diseases, especially those due to the absorjjtion of chemical bacterial poisons. The blood is firmly clotted after death from pneumonia, in which disease the fibrin-ferment in the blood is increased. The clot found in the vessels may resemble the clot formed outside of the body, or in certain places, notably in the heart, clots are formed wliich are colorless and transparent, and resemlde the clot obtained by whipping the blood and gatiiering tiie fibrin. Clots of this sort are not strictly ])ost-mortcm. For their formation a certain amount of motion in the blood is necessary, and it is probable that tliey form in the last minutes of life, especially under circumstances in which the power of coagulation is increased, as in crou])ous pneumonia. Three principal varieties of thrombi may be distinguished, and there are various intermediate stages. The white thrombus is of firm con- sistency and has a grayish, and sometimes a yellowish-white, appearance. On microscopic examination it is principally composed of white corpus- cles and fibrin. Many of the white corpuscles are apparently normal and their nuclei stain clearly ; others show every stage of disintegration. The fil)rin appears either in the form of very minute filaments, forming a meshwork and enclosing the leucocytes in its meshes, or the filaments may be large and coarse. At times the thrombus has a hj-aline, more transparent appearance, and this is due to the presence in it of large masses of hyaline material which stain in the same way as fibrin, and which probal)ly result from a hyaline metamorphosis of the fibrin. In many cases the fibrin is arranged in definite layers which may be stripped off. This is especially the case in the large thrombi formed in aneurisms. The whole space of the aneurism is frequently filled with lamelhe of fibrin. Along with the leucocytes and fibrin a certain nunilier of red corpuscles are generally found, and a quantity of granular material, which may result from disintegration of the fii)rin or white corpuscles, or may have another origin. The red thrombus is less firm than the white. The red color is due to a greater numlier of red corpuscles, or pigment resulting from their disintegration, entangled in the meshes of the fibrin. The red thrombus shows various degrees of color, depending upon the amount of blood- pigment in it, and is formed more rapidly than the white. In the mixed thrombus there is a combination of both forms. It frequently has an excjuisitely lamellated structure, a red lamella follow- ing a white in regular order. This mixture of the two colors is due to an alternation of rapid and slo«- coagulation on the surface. The consistency of the thrombus may differ in different parts. We can frequently distinguish a firmer portion of tiie thrombus to which 208 SURGICAL PATHOLOGY. tlie romaiiuler is loosely attai-liwl. Tlio firm jwrtion is the true tlironi- I)iis, which is clue to the loeal ciuise, and tiie other is simply a eoa<;ulum fdrmed on this. The soft red cnaLiidmii may extend t'nun tlie thrombus a considerable distance in tiie blood-current, and is called the sec(m(lary or continued thrombus. When a vessel is completely occluded the thrombus extends up to the next branch entering or given oif from the thrombosed vessel. True thrombi may l)e distinguished from post-mortem coagula in a number of ways. Thrombi are more consistent than post-mortem clots; they are more adherent to the walls of the vessels. The adhesion is due to several causes. If the thrombus be sufficiently old and if organization has taken place in it, there is a definite tissue-union between the thrombus and the vessel-wall. Even if there is not formation of tissue extending from the wall of the vessel into the thrombus, there is frequently a formation of fibrin in the wall of the vessel which unites with the fibrin of the thrombus. The thrombus may occupy various relations to the lumen of the vessel. It may fill up the entire vessel or occupy only a small portion of the wall, allowing the blood-current to flow past it. As a rule, thrombi are formed by coagulation over a small area of the wall of the vessel, and then successive coagula are formed on the first. In the heart these successive coagula may be formed until a large mass ]irojecting like a polypus into one of the cavities of the heart is produced. Another variety of thrombus is due to aggregations of the blood- plates. There is still much contention about these blood-plates and the part which they play in coagulation and thrombus-formation. It is held, on the one hand, that they are essential constituents of the l)lood, and on the other that they result from the disintegration of white cor- puscles. Eberth and Schimmclbusch, in studying the experimental formation of thrombi, found that the first appearance of the white thrombus was due to a collection of these blood-plates. They form with the greatest rapidity just at the point where the vessel is injured. They call the thrombus so formed the blood-plate thrombus. Welch has also found that thrombi which at first are entirely composed of blood-plates can be produced exjjerimcntally by slight injuries of the wall of a blood-vessel, and it hardly seems probable that all the leuco- cytes which had collected at such a place could have broken down. Weigert does not consider these aggregations of l)lood-plates as true thrombi. He considers the thrombus a true coagulation of the blood, and not an aggregation of some of its constituents. A consitlerable amount of granular material which is found in the thrombus may be composed of these blood-plates. Zahn studied the formation of thrombi in the veins of the mesentery of a curarized frog directly under the microscope. He found that -when a crystal of salt was placed in con- tact with the vein the first change noticed was a collection of leucocytes at the point. Finally, the entire lumen of the vessel was occluded by the leucocytes. In the course of some hours the thrombus underwent important changes. The white corpuscles lost their form and regular contours, and became changed into a more or less finely granular mass, and then fibi'in-filaments appeared. Both local and general conditions favor the formation of thrombi. THROMBOSIS AND EMBOLISM. 209 The local conditions favoring their formation are stagnation of the blood and changes or injuries in the lining membranes of the vessels. Exper- imentally, it seems to be shown that when the l)lood is enclosed in a vessel between double ligatures coagulation will not take place if the vessels be ligated so carefully that all injury to the wall is prevented. Even if \ve suppose that a lesion of the endothelium is necessary for coagu- lation, such a lesion may be produced by stagnation of the blood. The endcjthelium of the blood-vessels is nourished by the blood, and not only the blood, but its constant renewal, is necessary, and a loss of function of the endothelium due to lack of nutrition would suffice to produce coagulation. As a rule, the smaller the blood-vessel in which stagnation takes place, the less likelihood is there of coagulation. The larger the area of blood relatively to its mass ^vhich comes in contact Avitli the endothelium, the less readily will coagulation take place. In a small vessel degeneration of the endothelium would not be so likely to take place, because it could more readily be nourished by imbibition from the surrounding tissues. The thrombi produced by stagnation of the blood are formed first in the pockets behind the valves, where the stagnation is most complete. Thrombi may form around foreign bodies, but there is little opportunity given for this mode of formation in man. Virchow first called attention to the jiart which alterations in the walls of the blood-vessels play in tlie formation of thrombi, and regarded the coagulation as the result of altered molecular attraction between the wall of the vessel and the blood. Ulceration, inflammation, necrosis, and various other pathological conditions in the neighborhood of blood-vessels may so atfect their walls as to lead to thrombosis. Frequently the coagula- tion which takes place under such circumstances is essentially a con- servative process, and the hemorrhage which would otherwise follow the extension of the ulceration into a large vessel is avoided. Dilata- tions of vessels favor the formation of thrombi. The thrombus forms the more easily the more sharply circumscribed and the more partial the dilatations are. In such conditions, of which the best type is given in aneurism, the thrombosis is further assisted l)y calcification and various degenerations of the lining wall of the aneurism. Various conditions of the system favor the formation of thrombi. They are frequently found in ^veak marantic individuals, particularly when they have had long-continued supjiuration. In such individuals thrombi are frequently found in the pockets behind the valves of the veins, in the sinuses of the dura mater, and in tlic auricular appendages and between the muscular trabccuhe of tlie licart. Virchow considered the essential factor in the production of sucli thrombi the weakness of the heart and circulation. Even in such conditions the thrombosis may be favored by local .degenerations of the endothelium. The nutrition of the vessels will suffer in consequence of the diminution in the gen- eral nutritive power of the blood and the diminution in its rapidity of flow. Tiiese conditions will be felt most where local conditions favoring stagnation are present. There may be certain chemical alterations in the blood which increase its coagulability. The injection into the blood of the extracts of certain glands, especially of the thymus gland, increases its coagulability. Extracts of htemoglobin, especially the hsemoglobin derived from Vol. I.— U 210 SURGICAL PATirOLOGY. a different animal, lias the same effeet. There were numennis ex- amj)l(>s of this when the blood of different animals was used for trans- fusion. Under such circumstances death frequently occurred shortly after tlie transfusion, and at the autopsy extensive thrombosis was found. In certain cases tlicre may be such extensive thrombosis in the vessels that the existence of substances in the blood \\hich materially increase its power of coagulation must be assumed. These are cases in M'hich in a very short time, and apparently without any lesions in the walls of the vessels, there is extensive formation of thrombi. It is possible that substances may be formed in certain organs of the body, and may have a local influence in assisting thrombosis. There mav be extensive thrombosis, especially in the very smallest veins and capillaries, which occurs in the course of certain infectious diseases. The thrombi formed under these circumstances are different from the ordinary thrombi, being composed almost entirely of hyaline material. Such thrombi are fre- quently found in vessels of thi' kidney and the lungs. The thromlius when once formed nndergoes various changes. It contracts and l)ecomes firmer and harder. Softening frequently takes place, especially in large thrombi formed in the heart and large vessels. The thrombus becomes converted into a soft pulpy mass of an opaque granular appearance closely resembling pus. The softening most fre- quently takes place in the centre of the thnmibus. In the softened material of the thrombus there is a quantity of fatty granular material M'hich is derived from tlie breaking dt)wn of Ijoth the cells and the fibrin. The fluid in the centre is frequently surrounded by a dense outside wall. The fluid results both from the absorjrtion of fluid from the blood and the contraction of the thrombus. This softening may take place until the thrombus resembles a cyst filled with fluid. The thrombus may become organized and converted into a mass of connec- tive tissue. The manner in which the organization of the thrombus takes place has been the subject of a great deal of dispute among path- ologists, and the study of the jirocess has led to a material increase of our knowledge about this and tiie formation of pathological connective tissue in general. It was at first supposed that tlie connective tissue in the thrombus was formed by a direct conversion of the constituents of the thrombus into connective tissue. It is now known that the organ- ization of the thrombus is due to a growth of connective tissue into it from the wall of the blood-vessel. It is not probable that the white corpuscles in the thrombus itself take any part at all in the organization. In the first stages of the organization of the thromlius it becomes filled with leucocytes which are derived from the wall of the blood-vessels. In some cases it seems probable that there may l)e an invasion of the thrombus by leucocytes Avhicli are derived from the blood itself. After the leucocytes, and along with them, large epithelioid cells appear which are derived from the M'alls of the vessels. These cells are accompa- nied by a new formation of blood-vessels proceeding from the adjacent blood-vessels of the tissue, and a new formation of connective tissue takes place from the large epithelioid cells. The leucocytes ajipear to prejiare the way for the after-formation of tissue, and, as in the connec- tive-tissue formation in inflammation, it is jirobable that they to some extent furnish food for the growing cells. The thrombus in the course THROMBOSIS AND EMBOLISM. 211 of organization becomes filled with large dilated blood-vessels that fre- quently conmuinieate with one another. Under favorable circumstances communications may be formed between the blood-vessels of the throm- bus and the lumen of the vessel, and in this way the continuity of the lumen of the vessel may be again accomplished. The red thrombus in the course of time becomes decolorized and converted into a yellowish or yellowish-brown material. The thrombus may become calcified, and, in consequence of this, becomes converted into a hard, calcareous mass. The so-called vein-stones, or phleboliths, are due to calcification of thrombi. The calcification is due to the deposition of lime-salts in the thrombus. All of these changes in the thrombus are relatively favor- able. Other changes are not so favoralile. There may be an actual purulent softening of the thrombus. When there is purulent inflam- mation in the tissues around the tin-oml)osed vessel the suppuration may extend to the blood-vessel and into the thrombus. Not onl\- may the pus-cells M'ander from the vasa vasorum and enter the blood-vessel and thrombus, Init the pyogenic bacteria may also be carried by these. Under such circumstances no organization of the thrombus takes place, and it becomes converted into a soft friable mass. Embolism. Although the thrombi may produce both local and general effects on the circulation, these are not the chief dangers which result from them. In many cases the thrombus docs not entirely obstruct the wall of the vessel, and the blood circulates in the vessel beyond the thrombus. Even when the thrombus completely occludes the vessel, it extends up to the next collateral branch, and frequently beyond this, so that a por- tion extends into a vessel where the circulation is still taking place. The tin'ombi, further, are more frequently found in the \'enous side of the circulation than in the arterial. The chief danger from the thrombi is that portions may be Mashed off, carried into the circulating blood, and finally occlude arteries. The thi'ombi being more frequent in the venous system, the particles Mhich are washed off from them occlude the ves- sels of the lungs. When thrombi are formed in the left side of the lieart and in the arterial system generally, they M'ill be carried into some other part of the circulation. The particles of the thrombus which nray be broken off and enter into the blood-stream vary in size. The largest pieces come from the thrombi formed in aneurisms, from the heart-cavities, and from the large veins. These portions of the throm- bus which are carried by the blood-current to another portion of the body arc called I'lnholi. Where they will lodge depends upon the posi- tion of the thrombus. If they come from the veins, they will enter into the pulmonary a'rteries. Those from the arterial side — that is, from the left heart, the systemic arteries, and the lung-veins — are carried into the systemic arterial system, and those from branches of the jiortal vein into the branches of the portal vein within the liver. These emboli will be carried along by the blood-stream, and finally stop where the calibre of the blood-vessels is smaller than the diameter of the emboli. Virchow, and especially Recklinghausen, have called attention to the fact that there may be a transportation of thrombi in a direction contrary to 212 SURGICAL PATHOLOGY. tilt' blood-stream. It is difficult to sec liow this takes place. It may be assisted by gravity, and it can only take place in parts where the circu- lation is exceedingly feeble and the ])lood-pressure in the veins very low. Large emboli can occlude the chief branches of the pulmonary arteries, or on the arterial side may occlude large arteries, such as the renal or iliac, or even the descending aorta. The smallest emboli may enter into the capillaries, and where the cajiillaries are relatively wide, as in the lungs, they may pass through tlicsc, and afterward plug up the narrower capillaries of the systemic circulation. It is evident tliat solid particles whose diameter is smaller than the capillaries can pass unliindercd tiirough all parts of the circulation. The emboli are apt to bo found in places where the lumen of the vessel undergoes a sudden diminution in size, especially where large branches are given off. It is not uncommon to find emboli entering into each l)ranch of an artery at the place of its bifurcation. Such emboli are sj)oken of as riding emboli, situated as they are at the place of bifurcation, as in a saddle, with one leg in each division of the artery. The emboli almost always produce total occlusion of the vessel where they are found. They are carried with some force into the vessel, and being comparatively soft they will lie pressed into it mitil they totally occlude it. The emboli may undergo the same changes as thrombi. They can become softened or they may organize. There may be special varieties of emboli ^\'liich arc not due to thrombi, but which are due to substances accidentally introduced into the vessels. Under certain conditions either air or a fluid which will not readily pass through the ca])illarics, such as oil, may be introduced into the circulation. A large number of cases have been reported of death in human beings attributed to the entrance of air into the veins. This accident has generally happened in surgical cases where operations have been done about the neck, shoulders, and skull. Further, death has occurred in cases in which air has entered the sinuses of the puer- peral uterus, generally in cases of criminal abortion in which air has been injected into the uterine cavity. In some of these cases death has been instantaneous, and in these there seems to be no reason to doubt that it has been due to the entrance of air into the circulation and the stoppage of large areas of the vascular territory of the lungs. A con- siderable amount of doubt, however, has been thrown on such cases by the result of experiment. It has been shown that the amount of air which is required to kill a dog if the air is directly injected into the vessels is much greater than could possibly enter the vessels in a sur- gical o]>eration. If the air is injected slowly, enormous amounts can be injected without producing anything more than slight disturbances of the respiration and the action of the heart. In the cases in Avhich death has been attributed to the entrance of air into the veins a large quan- tity of air or gas is found in the blood-vessels after death. Welch has shown that this is frequently due to the growth of an aeroliic gas-pro- ducing bacillus in the blood. There is no doubt that a number of the cases which have been reported of death from air-embolism, in which death has taken place some time after the supposed entrance of air, have been due to infection with this bacillus, but there is equally no doubt that there have been cases of sudden death due to the entrance of not THROMBOSIS AND EMBOLISM. 213 very large quantities of air into the circulation. The air is especially apt to enter into the veins if there is an inspiration at the same moment when a largo vein, such as the jugular, is opened. When a large amount of air enters the heart at one time, death may ([uickly take place with evidences of sutfocation. This is due to collection of air in the heart. The air is not forced out of the heart at each contraction of the ven- tricle, but is simply compressed. When a small amount of air enters slowly it will enter into the circulation, and may produce temporary occlusion of a number of the capillaries in the lungs. Unless the vas- cular territory so occluded is very large there will be little inconvenience, because the air will gradually be forced through the capillaries by sub- sequent contraction of the heart, and in a short while most of it will become absorbed. The presence of fat-emboli in the vessels of the lung has attracted considerable attention, but the importance of these emboli has been very greatly over-estimated. The fat of tlie l)ody is in a fluid condition dur- ing life, the fat-cell representing a drop of fluid oil enclosed in a vesicle. Wiien a number of these vesicles are broken, as in extensive crushing injuries, and the veins are ruptured at the same time, a certain amount of this fluid fat can enter into the circulation. It is especially apt to do this in injuries of the bones where there is not only a large amount of fat in the marrow, but where the veins are large and do not collapse. The fat entering the circulation in this way is nearly all stopped in the capillaries of the lungs, and may be found there at autopsies. It was at one time supposed that the shock after severe surgical injuries could be in large part explained by fat-embolism. It is rare, however, that the fat is jireseut in sufficient amount to produce any serious results by occlusion of the capillaries. The collateral circulation in the capillaries is so abundant that no result can take place from the occlusion of a few. It is only when all of the capillaries of a very large area are occluded that any results will follow. The General and Local Effects of Thrombi and Emboli. An occluding thrombus in any portion of the venous system will lead to congestion and increased venous pressure in the vein behind the thrombus. The severity of the changes produced will depend upon the local conditions of the circulation in the part and the size of the vessel. If a large vein be occluded, it is evident that the consequences will be more serious than if the vein l^e a small one. Local conditions of the circulation aftecting the results produced by a thrombus are due to the abundanc.e or absence of collaterals. When there are two veins leading from a part with "an abundant anastomosis between their branches, the occlusion of one of tliem will have no eifect. The rapidity witli wiiich the thrombus is formed will also influence the result. If the renal vein be ligated, intense passive congestion of the kidney with hem- orrhage and necrosis results. Com])lete occlusion of the renal vein by a thrombus is sometimes seen without producing any results. The thrombus is formed slowly, and time is given for the dilatation of the vessels of the collateral venous circulation, so that by the time the occlu- sion is complete these vessels are sufficiently dilated to carry off all the 214 SURGICAL PATHOLOGY. blood fnini the kidney. Tlic same tiling is true of the portal vein. AVhen thi.s is ligated death results from the enormous distention of its branc^hes. When it is slowly oeeluded by means of thrombus-forma- tion the few collateral brancdies dilate sufficiently to carry off the main portion of the blood, although the collateral circulation is rarely suf- ficient to prevent ascites and passive congestion. Sudden occlusion of the femoral vein in the neighboriiood of Poupart's ligament is usually fiital. Intense congestion, eedema, and gangrene of the entire leg- develop. When the occlusion takes 2)lace gradually by the slow forma- tion of a thrombus or by pressure of a tumor, no unfavorable conditions other than oedema to a greater or less degree may develop. The local effects of an embolus will depend to a certain degree upon the physical character of the emljolus. Virchow found that when hard substances, especially those with irregular walls, were introduced into the cii'culation, they produced intense inflammation, frequently with rup- ture of the vessel at the point where they were arrested. Wherev^er an embolus lodges and whatever its character, it Avill al\\ays ])roduce ciianges in the wall of the vessel in contact with it. The endothelium will become necrotic, and the necrosis may extend some distance into the surrounding tissue. Other local changes may be produced which do not depend upon the physical characters of the embolus, but upon its biologi- cal characters. The embolus may consist of living tissue, which may grow where it lodges. Particles of tumor are frequently carried by the circulation from a primary focus to a distant organ, and develop, forming secondary tumors where they lodge. Not only particles of living tissue, but living organisms, may be contained in the embolus, and these will produce the same lesions as in the place from which they were derived. This is especially seen in the emboli which come from the purulent soft- ening of a thrombus. In this way a secondary abscess may be formed around an embolus. The occlusion of an artery will jtroduce effects in the tissue supplied by it. Here the effects produced will depend upon the presence or absence of collateral branches going to the same tissue. In certain parts of the body definite areas of tissue are supplied by definite arteries without anastomoses. Such terminal arteries are found in the kidneys, heart, and other organs. Tiie effect produced will also dci)end upon the size of the artery. " The collateral circulation may suffice for a small area, but not for a large one. There may be prculuccd by the occlusion of an artery two conditions which are apparently widely dif- ferent. If the artery be a terminal one, the tissue supplied by it becomes necrotic. The form of necrosis produced is that described by Weigert as coagulation-necrosis, in which there is necrosis of the cells with coagulation. The anremic part has a whitish, opaque character, and is generally triangular in shape, the ajiex of the triangle being formed by the occluded artery. Or a hemorrhagic infarction may be produced. In some cases hemorrhage takes place into the previous anajmic territory. The source of the blood in this case has been a matter of dispute. Cohnheim supposed that it was due to a backward flow from tlie veins, but this can be shown to be erroneous, because the infiirction takes place Avhen the veins are tied at the same time \\ith the artery. The blood may have various sources. It is impossible by arterial occlusion to shut HYPERTROPHY AND REGENERATION. 215 oft' all blood from a part. There are always anastomoses with the capil- laries of a neighboring part, and if the ansemic area be very small the capillary anastomoses will be sufficient to preserve the life of the tissues. The first effect of arterial occlusion must be to lower the pressure in the circulation distal to the occlusion. The pressure will be lower in all the vessels of the part, and the blood will ffow into it from all the adjacent vessels. The blood-vessels become distended and diapedesis of red cor- puscles takes place. If the amount of Idood entering the vessels of the part is not sufficient to provide ibr a regular circulation, all of the tissue becomes necrotic. The diapedesis is generally supposed to be due to nutritive changes in the walls of the vessels, but it may Ite the result of changes which ha\'e taken place in the character of the blood. A comljina- tion is frequently seen between hemorrhagic and ansemic infarctions. The centre of the infarction may be white and anremic and be surrounded by a hemorrliagic zone. In this case sufficient Ithiod ddcs not enter the vessels to penetrate to the centre, or necrosis with coagulation may take place before it has sufficient time to do so. Various conditions of the body may influence the effects jjroduccd by an embolism. If the circu- lation is feeble and the general state of nutrition poor, the effect will be more disastrous. Embolism of the pulmonary arteries, unless the vessel be of considerable size, may not produce any effects. In the ordinary conditions of the pulmonary circulation there is sufficient ca])illary anastomosis, assisted by the anastomoses of the bronchial artery, to pre- serve the life of the tissue. In any embarrassment of the pulmonary cir- culation, especially in chronic passive congestion, infarction alwaj'S results. That a part is able to retain its vitality after the occlusion of a large artery supplying it with blood is due to the development of the collateral circulation. After the ligation of the femoral artery below the point ■where tlie jirofunda is given off, the leg not only retains its vitality, but in a short time it will be able to perform all its functions as well as before. It must receive the same quantity of blood, and it cannot do this unless the other arteries dilate. No adequate explanation has been given for the dilatation whicli takes place. It cannot be explained on physical grounds, ijecause tying the artery does not produce any increase of pressure in the branches given off' above the ligature. Tlie dilatation of the collaterals in this case is more complicated. Every tissue receives just the amount of blood which it needs for its nutrition and function, but no more. The varying amount is provided for by varying degrees of contraction of the muscular walls of the arteries. Where a small artery has to supply a large part with blood, it not only dilates to the fullest extent, but the calilire of the vessel actually grows larger. The dilatation is the result of the close relation between the calibre of the arteries and the needs of the tissue — a relation probably directly under nervous control. IV. HYPERTROPHY AND REGENERATION. Ix hypertroijhv there is an increase in the size of an organ or part of the body, with retention of the normal structure. In regeneration a loss of substance in an organ or part of the body is restored by a tissue similar to that which is lost or M'hich contains the same constituents. 216 SURGICAL PATHOLOGY. A tissue ran cnlargo either by ;iii increased power of assimilation or growth, or hycliniiniition of the consumption of the tissue. Sucli a con- dition is physiological during the entire period of growth. When a part is growing, more tissue is formed than is used up. The normal size of organs and the general conditions of growth depend upon causes which are inherent in the germ. In order that growth may take place an abundant nutrition is necessary, which is provided in the intra-uterine life by the mother and in extra-uterine life by alimentation. The growth of the individual tissues and organs is dependent also on the activity of the blood- and the lymph-circulation. An extremity of a child ceases to grow, or it may even diminish in size, when for any reason the blood- supply is diminished. If all the conditions of nutrition are favorable, and if there are no general disturbing iuHuences acting on the tissues, such as abnormal temperature, for instance, the development and growth of every individual take place at a rate corresponding to the age. The influence of the nervous system for such growtli as this is not absolutely necessary. Examples of this are given in the monstrosities in which children are born without either brain or spinal cord. In these cases the body may sometimes show a develo[)ment even in excess of the normal. The cells apparently from the beginning have the {>ower of excessive reproduction — that is, reproduction in excess of the material used up — for a certain length of time, which differs in different animals. This ceases in man at about the twenty-second year, and nothing can again excite it. This does not hold for certain tissues ; as, for instance, for muscles, for glands, and for the ejiithelial tissues generally. In these the power of forming new substance does not cease with the end of the period of growth. Every muscular contraction and every secretion of a gland takes place at the expense of the substance of tlie muscle and the gland ; and in order to supply this continual loss there must constantly be a new formation of contractile substance or of gland-cells. Even in the adult there may be an increase in the size of certain parts brought about by exercise and good alimentation. Arterial congestion, however, no matter how excessive, will not of itself produce an increased growth. Apparently the cells of the muscles and glands will only assimilate when they are stimulated, and congestion alone will not produce contraction in the muscle nor increased secretion in a gland. In other tissues assimila- tion and new formation apparently only depend upon conditions which govern the growth ; that is, the inherent power of reproduction and the degree of congestion. In all of these tissues an excess of production may take place when they are subjected to constant hypersemia. Cohn- heim thinks that the growth of these tissues is due alone to the regula- tion of the blood-supply. He says that the bones and epidermis cease to grow at the end of the growth period, merely because if all the other organs of the body are supplied with blood in the proper measure, the quantity of blood which they receive will not be sutiicient to excite growth. The increase of size of organs due to increased functional activity with inci'eased blood-supply is familiar to us in the muscles and in the glands. When more ^^'ork is thrown on the heart in conserjuence of increased pressure which has to be overcome, or in consequence of lesions of the valves, that portion of the heart which is called upon to do HYPERTROPHY AND REGENERATION. 217 an increased amount of work beeomcs cnlartjcd. An enlargement of the muscular walls of tiie bladder, wliich relatively can exceed tliat of tiie heart, takes place when, because of stricture of the urethra or enlarged prostate, it is forced to do a greater amount of work in expelling its contents. The same thing may be seen in the glands. AVhen one kidney is destroyed, the other can undergo such an increase in size and weight that it will correspond to both kidneys and properly perform the func- tions of two. In other glands wliich are not necessary for the life of the individual, but only for the jtreservation of the species, as the testicles in man and the ovaries and nianimarv glands in the female, such a com- 2:)ensatory hypertrophy does not take place at all or only to a very limited degree. Hypertrophy only occurs when in consequence of the loss of one organ a gi-eater amount of work is thrown upon another organ ; and this will not be the case for the testicle or the ovary. Extirpation of a jiart of the thvroid gland will lead to an increased size of the part which remains ; not only that, but other glandular structures whicli probaljly have the same function will also undergo an increase of size after extir- pation of a part of the thyroid An increase in the functional activity of one portion of one lung in consequence of inactivity in other portions will simply produce a distention of the alveoli of the lung which may lead to atro})liv instead of hypertrophy. In general, the younger the tissue the more readily will compensatory hy[)ertrt)j)hy take place. In tissues which are constantly being used up a diminished consumption may also produce hypertrophy. For instance, in the epidermis and the nails there is constant consumption of the horny layer, and anything which interferes with this constant rubbing off may lead to pathological thick- ening. The removal of pressure from tissues can also lead to new form- ation of tissue. The inner surface of tlie skull can become thickened when the growth of the brain in childhood is inhibited. Frequently- repeated mechanical and chemical irritation of the tissue may lead to liypertrophy. Repeated irritation of the skin can lead to the production of callosities and corns. The continuous inhalation of dust can lead to development of connective tissue in the lungs, but this cannot be consid- ered as hyjiertrophy in the true sense of the word. It is rather a repro- duction of tissue to take the place of that which was lost, and the new tissue has not the same structure and function. The cause of hyper- trophy in many cases is entirely unknown. Formerly a sharp distinction was made between hypertrophy and hyperplasia. By hypertrophv, strictly speaking, we understand an in- crease in the size of an organ due to an increased size of its constituent elements, without any new formation. In hyperplasia there is a new formation of tissue. These terms can be used interchangeably, for in hypertroj)hy there is-always hyj)erj)lasia. It cannot be always assumed that \\hen an organ is increased ni size there is at the same time increased functional capacity, because the liyjiertmiihy may not concern all parts of tlie organ. When a gland is increased in size, this may be due to an increase in all of the elements of the gland, or only the connective tissue may be increased in amount. This imperfect new formation of tissue can reach such an extent that hy]iertrophy may take place in one tissue of the gland while the other part undergoes atrophy. In such cases it is generally the specific constituents of the tissue, the ganglion-cells, the 218 SURGICAL PATHOLOGY. nerves, the gland-cells, etc., that are atrophied, while the connective tissue increases in amount. One of the most striking examples of this is seen in the pseudo-hypcrtrojjhy of the muscles. Although the muscles appear to l)e enormously increased in size, this is not due to an increase in the contractile substance. Hypcrtrojjhy may also take place in the jicriod of embryonic development or during the period of extra-uterine growth without our being able to assign any cause whatever for the increased growth of the tissue. The power of regeneration in tissues is always more or less limited. Tlie more highly develo])cd tiie tissue, the more its elements are differ- entiated for particular functions, the less complete is the regeneration. In the lower animals the power of regeneration exists to a very much greater extent than in man. Whole extremities of crabs and lobsters can be regenerated, and even in the lower vertelirates the same power exists. Tiie yotmger the animal the greater the jiower of regeneration. In man the power of regencrati the nucleus, and then the various changes in the nucleus take place. Divis- ion of the cell so brought about is known as the karyomitotic, or the indirect cell-division. It was at first supposed that this was the only way in which cell-division took jilace, but there is also a direct division of the nucleus. This form of cell-division is seen both in the leuco- cytes and in the lym]ihocytes. Tile formation of new cells is the first stage in regeneration. The new cells provide the formative tissue from which the typical tissue of the part is developed. In the regeneration of tissues the different embryonic tissues only produce the same tissue. The epithelial cells can under no circumstances produce cartilage or bone, nor is a connec- tive-tissue cell able to produce cither the surface or the glandular epi- tlielium. This law was formerly not so clearly known, and many authors believed that the most different tissues could be formed from connective tissue. In the formation of the epithelial tissues the cells become united to one another by intercellular substance, the structure conforming to the type of the normal tissue. In the formation of con- nective tissue the most prominent feature is the formation of intercellular sulistance from the cells, and the eharai'ter of this intercellular substance gives the various connective tissues their ])eculiar properties. In order that hypertrophy or regeneration of the tissue may take place the cells must have the power of multiplication. Most of the cells of the body possess this ])ower, but others seem to have apparently lost it. These are cells which in the course of development have undergone a marketl differentia- tion. The more the jirotoplasm of the cell departs from the t3'pe of the embryonic cell by differentiation for sjiccific purposes, the more does it lose its power of regeneration. The horny layers of the epidermis, the non-nucleated red blood-corpuscles, the ganglion-cells of the brain of an adult, all seem to have lost their power of multiplication. The more inilifferent cells, such as the connective-tissue cells, those of the bone- marrow, of the spleen, of the lympli-glands, and certain of the epithelial cells, have retained this power to a marked degree. The power of multiplication is one inherent in the cells themselves, and even when separated from their surroundings and placed in new localities they are still able to proliferate. On this power of groMiih depends the possibility of the successful transplantation of tissue ; that is, the transference of a piece of tissue from one place into another part of the body. Pieces of the periosteum or of the bone-marrow have been placed in various parts of the body or in blood-vessels, and have 220 SURGICAL PATHOLOGY. there grown and devclojjed normal tissue. The experiments which Jolin Hunter made in transplanting the spurs of young eocks into the comlj, where they grew more actively than in their normal situation, are well known. The tissue most frequently used for transplantation is the skin, and this method may be used to make up even large losses of substance. The great power of reproduction in embryonic tissues has been shown by experiments in the transplantation of tissue. The cartilage of an adult animal either does not grow at all or makes a very feeble growth when transplanted to new tissue. Portions of embryonic carti- lage so transplanted lead to an excessive growth. Leopold and Zahn transplanted pieces of embryonic cartilage into the anterior chamber of the eye and obtained a considerable new formation of cartilage. The transplantation of tissue must be done in animals of the same species, because the blood-serinn and tissue-juices of an animal of one species generally have a poisonous action on the cells of an animal of another species. The transplanted tissue must also have a certain amount of cohesion and firmness, otherwise tiie intercellular substance will be dis- solved out and the tissue destroyed. It is prol^able also that the cells need contact with the adjoining cells — that they derive mutual sup- port from each other in their efforts to live in strange surroundings. In general, the growth of the tissue transplanted is limited. This is especially the case with pieces of tissue wliich are implanted deeply in the body. Growth only goes on for a certain time ; it tiien ceases, and the cells may disappear by absorption. As a rule, transplantation of the skin is not only the most useful, but is the most successful. The transplantation of skin can be made both on fresh and granulating wounds, especially tm wounds \\inch are covered with vascular, actively- growing granulations. Large thin pieces of skin whirli have l)een cut off Avith a sliarp knife, and which consist of only the epitlermis with the cut ends of the papilhe or only the upper portion of the corium, may be placed on fresh granidating wounds and kept moist. The adhesion of the tissue takes place by means of the lymj)ii or blood. After about eight days the transplanted tissue becomes firmly united with the tissue beneath. Portions of the tissue may be kept for several hours in normal salt-solu- tion before they are used for transplantation. The nutrition of tiie trans- planted piece of tissue appears to take place first by means of the imbibi- tion of nutrient material from the juices of the tissue. Later, a germinal tissue bearing blood-vessels grows up into the transjilanted tissue. In some cases it appears to be e\'ident that a direct connection is formed between the blood-vessels of the transplanted tissue and those of the old tissue. It is hardly possible to suppose that the ti-ansplantation of large parts — such as the entire finger, for instance — would be successful were this not the case. It would appear impossible for an entire finger to receive sufficient nutriment l)y means of imljibition to keep alive. Before new blood-vessels could grow from the Ixise of the finger into the severed part necrosis would certainly take place, yet we Iviiow that portions of the finger, and even entire fingers, may be cut off and kept for some time, and then be successfully replaced. When the surface epithelium is transplanted the horny layer is cast off, and the adhering tissue at first consists only of the lower layer of germinal tissue, upon which a new horny layer is formed. HYPERTROPHY AND REGENERATION. 221 The process of pigmentation in the skin has been stndied by means of the transplantation of epithelium. It has been found that when the skin of a white man is transplanted on a negro the transplanted skin soon becomes pigmented, and the pigmented skin of the negro loses its pigment when transplanted on a white man. This e.\})erinient shows clearly that the skin-jjigmcnt is not formed in the epithelium, but is derived fr<;>m cells in the tissue lieneath, which have the physiological power of forming pigment. The question as to the cause of pathological new growth of tissue in regeneration and the conditions necessary for it to take place is quite obscure. One of the theories with regard to this, and «hicli appears to be very plausiljle, is that the cells of the tissue have an inherent jwwer of growth wiiich is held in check by their relations to the surrounding tissues. When this relation is altered in any way, as when a loss of substance takes place, the cells in the vicinity, having the inhibitory influence of the surrounding tissues removed, proliferate actively. Other observers believe that the cells have a certain irritability, a power of action which may take the form of growth, and under the influence of certain conditions of irritation they may be excited to growth. Among the influences which increase the capacity of proliferation of the cells, and which lead to a new formation of cells, increased nutri- tion brought about by hypcrremia has an important place. It is certain that this congestive hypenemia makes possible an increase in the nutri- tion of the cells. It is prol)aljly necessary for cell-proliferation, but it is not probable that this ah)ne leads to proliferation. The cells are not nourished, Ijut they nourish themselves. In general, it is probable that proliferation of the tissue in regeneration should be regarded as a second- ary process which in most cases depends upon a removal of the restric- tions of growth. In various attempts which have been made to excite growth by chemical and mechanical irritation a lesion of the tissue, a trauma of some sort, is always produced. It may take the form of a direct loss of substance or of necrosis. The regenerative changes whi(^li take place in the epithelium are relatively simple. Division of cells takes ])lace by means of karyokinesis, and may be easily studied. In epithelium composed of several layers cell-division appears to take place only in the cells of the deepest layers near the lilood-vessels. These cells are always younger than the others, and their protoplasm has undergone no differentiation. The formation of keratin, represent- ing a differentiation of the cells of the skin, only takes place after the cells have been produced a certain length of time and are removed a certain distance from the centre of growth. In the regeneration of any tissue the new formation of cells does not seem to take jilace from any part of the tissue at random, but onlv from certain porticjus of the tissue". This was first studied by Flenniiing in the lymph-gland, and he found that in the gland there are certain cen- tres of growth which he described as the " keimcentren." In the liver such places are seen in the periphery of the lol)ule, and in the skin in the lower layers of the e]iithelitnn. It is very ]irobable that this is due to more favorable conditions of nutrition of the cells in these centres of growth, but it may be that in these places certain cells retain their embryonic power of growth. The newly-formed cells frequently have 222 SURGICAL PATHOLOGY. not the same morphologicuil and functional character as the old, and may approach the embryonic type. In tlic new formation of epithelium in the lungs which takes place in chronic inflammation accompanied with extensive loss of epithelium lining tlic alveoli, the newly-formed cells iu the alveoli frequently have the character of columnar cells. On sur- faces which are lined with ciliated epithelium the newly-formed cells do not acquire cilia for some time, and in the place of ciliated epithelium pavement epithelium may be formed. This is frequently seen in the healing of ulcers of tlie larynx and trachea. Small losses of sul^stance in the surface cpitlielium are usually (piickly replaced by growth of tiie epithelium in the neighborliood. Loss of substance in the glandular epithelium is quickly replaced in case the structure of the gland is not altered. Thus in the kidney the loss of single cells in the epitiielial tul)ules after intiannnation accom- panied by desquamation is cpiickly restored by regeneration jiroceeding from neighboring cells without any permanent lesion being produced. If, however, the structure of the tissue is destroyed and the relation ■with the surrounding tissues altered, complete regeneration is not apt to take place, and the site of the loss of substance is occupied by cicatricial tissue. In glands in wiiich two sorts of epithelium are found — as the liver, for instance, in which we find both liver-cells and bile-ducts — in cases of loss of substance, regeneration takes place more readily and more extensively from the bile-duets than from the liver-cells. The ejiithelium lining the bile-ducts is of the same character as that of the liver-cells, and represents a condition more nearly approaching the embryonic state. In some cases after loss of substance in glands a new formation of gland-tissue takes j>lace in the same way as in the embryo. In the compensatory hypertrophy of one gland which follows the loss of a gland of similar structure and function there may be both an increase in the size and function of the epithelium of the remaining gland and also a new formation of tissue. This has been studied in the growth of one kidney which follows after removal of the other, but it is riot yet fully understood. It is not certain whether there is a new for- mation of complex structures in the kidney, such as the glomeruli, or whether these simply increase in size and in functional capacity. If new glomeruli are formed, this could only take place by a general return of tlie tissues to the embryonic condition. New tubules must be formed, and at the end of these glomeruli must be produced in the same manner as in the embryo. In the growtii of tlie kidney which takes place before the adult size of the organ is reached there does not seem to be any new formation of glomeruli, wiiich simply undergo an increase of size. The younger the kidney, the smaller the glomeruli. In the epitliclium lining the intestinal canal extensive processes of regeneration may take place." In the healing of large typhoid ulcers of the intestine, ju&"t as in the healing of ulcers of the skin, there is a new growth of epithelium which extends from the edges and covers over the loss of substance. In the newly-formed epithelium the simple glandular crypts are produced, but the more highly differentiated structures, such as tiie villi, are not. The newly-formed glands are not so numerous nor do they have the same typical structure as in the normal intestine. Sometimes in the process of epithelial regeneration the new forma- HYPERTROPHY AND REGENERATION. ' 223 tion of tissue may be far in excess of that ueccssary to supply the defect. The epithelium in every part of the body, especially the surface epithe- lium, has an almost unlimited power of growth. If there is a definite chaut;e in the character of the connective tissue beneath it — if the nor- mal connective tissue, for instance, is replaced by a tissue containing great numbers of cells with a small amount of loose intercellular sub- stances — the epitlielium grows downward into such a tissue. At the edges of ulcers of the skin this atypical growth of epithelium may take place to such an extent that the structure of a typical epithelial carci- noma may lie produced. The growth of the epithelium only extends into the pathological connective tissue, and the normal tissues are not invaded bv it. In cases of intestinal suture tlie epithelium of the crvjits of Lieberkiihn grows downward through the suture, and an extensive growth, resembling an adenoma and extending even to the peritoneum, may take place. In all processes of regeneration new formation of blood-vessels plays an imjiortant part, because only by a new formation of blood-vessels can the excessive nutrition which is necessary for regeneration be brought about. New blood-vessels will be formed even in non-vascular parts, as in the cornea. The new formation of blood-vessels has been sufficiently considered in Inflammation. Tlie diffi'rent members of the connective-tissue group show a marked difference in their respective powers of regeneration, which are most active in the periosteum, the Ijonc-marrow, and the lymphoid tissue. The cartilage, on the other hand, is capable of only a slight power of regeneration. On the second day after fracture of bone the cells in the vicinity of the fracture enlarge and multiplication begins. In the physiological regenei'ation of tissue the newly-formed cells take the place of the old. It is simply a growth of tlie old tissue, without any intermediate steps and without any alterations of structure. When a large amount of young tissue is formetl in a short time, the character of the old tissue is not immediately reproduced, but the growing cells and the blood-vessels form a germinal tissue which is usually known as granulation tissue. The extent to which this is produced varies in dif- ferent cases, and depends upon the cajwcity of growth of the tissue on the one hand and the extent of the lesion on the other. After fracture of bones an excessive amount of this germinal tissue may be produced. The growing cells are larger and richer in protoplasm than the cells of the old tissue. They may have one or two nuclei, and sometimes cells with numerous nuclei, the so-called giant-cells, appear. All the cells may unite in the formation of the future tissue. Wlien connective tissue develops from sucli cells they arc known as fibroblasts or inoblasts. The formative cells of cartilage and bone have I'eceived the name of chondroblasts or osteoblasts. The most varying forms of cells are seen in the forming connective tissue. The first step in the formation of the definite tissue is seen in the appearance of fine fibrillar bundles between the cells, or a homogeneous intercellular substance may be formed which afterward l^ecomes differentiated into fibrillie. The for- mative cells increase in size, and finally lie in small spaces in the tissue. In the development of hyaline cartilage a hyaline ground substance appears between the cells, and the chondroblasts assume a round form. 224 SURGICAL PATHOLOGY. As tlie ground substaiicp increases tliese cells heconie smaller, and finally lie in round spaces, tiie wall of wiiicli forms tiie capsule of the curtilage- cell. The formation of new osseous tissue is a very complex process. In this a homogeneous or fibrinous substance forms between the cells, and afterward becomes infiltrated with lime-salts. The forming cells become smaller, and finally lie in small irregular cavities, and are designated as bi)iie-cells. When there is an abundant formation of germinal tissue tiiis direct change of the tissue into bone is limited. Within the ger- minal tissue an irregular meshwork of firmer tissue may apjiear, due to the formation of firm homogeneous tissue between the cells. This is at first not calcified, and is known us osteoid tissue. Afterward the inter- cellular substance becomes impregnated with lime-salts. The newly- formed osseous tissue is very extensive, being softer and looser in struct- ure than the old bone, and the gradual conversion of this newly-formed tissue into a tissue similar to that of bone is quite a slow process. Mucous tissue is formed from the germinal tissue by the formation of homogeneous, gelatinous, intercellular substance which contains mucin. Mucous tissue frecpiently represents a transitory stage of growing con- necti\e tissue, and it may be afterward converted either into fat or into fibrillar connective tissue. Adipose tissue may develop in places M'hich normally contain fat or it may form in any of the connective tissues. The regeneration of the blood is a process which is not well understood, in spite of the frequency with which it takes ])lace. The blood is a very complex tissue, containing a nimiber of elements of different origin. The formation of the round mononuclear cells of the blood takes |)lace in the lymphatic glands, and these cells are simply taken into the blood from these glands. We know very little about the for- mation of the polynuclear leucocytes. This takes place in the bone- marrow and in the spleen, Ijut the various steps connected with it are not known. There are cells in the blood which are regarded as pro- genitors of the polynuclear leucocytes, though the number is too small for us to regai'd them as the only progenitors of these cells. The new formation of red corpuscles is better understood. It is supposed that they are formed in the bone-marrow from certain cells which are called erythroblasts, by conversion of the protoplasm of the cells into the red corpuscle, the nucleus becoming extruded. New formation" of muscular tissue takes place only to a limited extent after loss of substance. The increase of size of the muscles in hypertrophy is principally due to increase in size of the muscular fibres. After injury or loss of substance in the muscle the muscle-nuclei become elongated and divide. The cells of the connective tissue and sarcolemma also show rapid proliferation. The substance of the muscle between the nuclei becomes broken up into larger and smaller masses, so that the muscle-cells lie in spaces between these fragments. The fragments are absorbed, and a new formation of muscular tissue takes place from the newly-formed cells. The process is quite a slow one, and is frequently not completed until two months after the injury. When the loss of substance is extensive there is never sufficient new formation to com- pletely supply the defect, and the gap is occupied by connective tissue. Regeneration of the cellular constituents of the central nervous system DEATH; XECBOSIS ; ATROPHY; DEGEXEBATION. 225 does not take place in man, or in the mammalia generally, in post-embry- onic life. When there is a small loss of substance in the central nervous system a formation of connective tissue takes place ; if the loss is large, a cyst is formed. New formation of nerve-fibres of the peripheral ner- vons system is frequently seen. It takes place in all cases when nerve- fibres are cut across or in any way jxTrtially destroyed. Degeneration always takes place in the iieriplieral part of the nerve-fibre after section or iiijurv of any sort. The central i)art, having a connection witli the nerve-cell, preserves its vitality, and from this growth takes place. Regeneration begins in the central stump of a nerve a very few days after section, taking place by a growth of the axis-cylinder of thecen- tral end of the nerve. When the peripheral degenerated nerve is in contact with the central end, the growing fibres will extend along the old ner\e to its muscular or sensory distrilnition. Tlie presence of the old nerve gives the proper direction to the growing fibres. If the grow- ing axis-cylinders do not reach the old nerve, they may extend for some distance iii the connective tissues, but more usually they either undergo atropliy or take various directions into the surrounding tissues and are finally lost. Regenerative processes may also take place in the central ends of the nerves after amputation. The regenerative gi'owth may be considerable, and large masses composed entirely of a convolution of rolled-np nerves may appear on the cut ends of the nerves. These are called " amputation "neuromas," and frequently give rise to a great deal of pain. V. DEATH; NECROSIS; ATROPHY; DEGENERATION. The tissues of the body are only capable of existing and preserving their function for a certain length of time. Their power of regenera- tion becomes less and less as age advances, and finally the regenerative processes are no longer able to keep jiace with the i-apidly-advancing processes of degeneration. Deatli from old age may be attributed to the gradual wearing out of the organs and the gradual loss of resistance which the diminution of the powers of regeneration entails upon them. Life ceases with the gradual destruction of the function of one organ after another. Destruction of the function of the heart, of the lungs, or of the nervous system produces death in a very short time. After desti-uction of the function of the intestinal canal, of the liver, or of the the kidneys the organism as a whole is just as certainly deprived of life, but some time may elapse befoi'e death takes place. In contradistinction to this general death of the organism the local death of a part, or of single cells or groups of cells, is called necrosis. Witii the api)earance of this' local death or necrosis, affecting groups of cells or an entire organ, changes of structure take jilace. These changes of structure occur so gradually that it is impossible to deter- mine the exact moment when the cells cease to live, and frequently in the early stage of necrosis neither the microscopic nor the macrosco])ic appearance is sufficient to tell us whether necrosis has taken place. The causes of necrosis of the tissue are various. The tissue may be destroyed by direct mechanical or chemical action. A finger can be crushed by Vol. I. — 16 2'2C) SUJROICAL I'ATJlOLOdY. external violence; a portion of the skin may he destroyed hv sulphuric acid ; and germs may destroy tissue in which they develop. The thermic death-point of protoplasm lies between 54° and 60° C. If tissues are exposed to this degree of heat ibr a short time, necrosis is ]iroduced. Lowering the temperature does not seem to exert the same uuliivorahle intlueuce. Even in niaunnals portions of the body may be (•om])Iet('ly frozen for a short time and afterward be restored to function. \\'hen the tissues do not receive the proper supply of blood their function and resistance may be impaired, and if the blood-supply be sufficiently reduced necrosis results. This form of necrosis is called anremic necrosis. Examples of it are given in the various infarctions due to artei'ial occlusion. The neuropathic necrosis is due to interference with, or inhil)ition of the function of, the trophic nerves. Regeneration of the tissue and nutrition generally are largely imder the control of the nervous system. Regeneration does not take place so completely when the nervous supply of a part is destroyed. Samuel found that when the long feathers of the wings of pigeons are pnlleil out they are only incompletely regenerated when the nerve of the wing has l)een cut. The supposed trophic influ- ence of the nerves, however, cannot be separated from the action of the vasomotor nerves which accompany them. As examples of necrosis due to interference with the functions of the trophic nerves the rapid and severe bed-sores which develop in the course of certain diseases, espe- cially after injury of the spinal cord, are cited. Any condition which in any way interferes with the circulation in a part, such as thrombosis, embolism, closure of vessels by continual tonic contraction, by lesions of the walls, by ligature, by pressure from with- out, inflammation, hemorrhage, etc., can ])roduce necrosis. In certain tissues temporary cessation of the circidation lasting but a short while may produce necrosis. The various tissues have varying powers of resist- ance to disturbances of the circulation. In general, the more highly organized the tissue is, the more rapidly does it succumb. The epithelial cells of the kidney will undergo necrosis when the circulation is shut off for only one or two hours. The ganglion-cells of the central nervous system are also very sensitive. Other tissues can withstand the shutting off of the circulation for a very much longer time. The skin, the bone, and the connective tissues generally may live for ten or twelve hours after the circulation has been cut off'. Cases have been known in which small portions of the body, such as the fingers, have united perfectly when replaced six hours after removal. If the circulation in the tissue is imperfect or its nutrition in any way interfered with, as in general marasmus or hydriemia, it undergoes necrosis much more easily than a perfectly normal tissue. Necrosis takes place much more readily in old peojile and in those in whom the action rm of hyaline material stains in the same way as fibrin, and it is probable that it is identical Avith it. The newly-formed connective tissue in chronic inflanmiations may be converted into a homogeneous, firm mass in which no cells are found. This is also spoken of as hyaline, but it must be regarded as entirely different from the other forms of hyaline. It is probable that we shall know little of these forms of degeneration until the chemistry of the process shall be in some way discovered. Amyloid Degeneration. Under certain conditions a peculiar albuminous substance, called amyloid, is deposited in the tissues. This deposition may take place in almost all the organs of the Ijody, but a]i]iears most often, in the order given, in the spleen, the liver, the kiody are those found in the urinary j)assages. They may form either in the kidney, in the ureter, or in the i)ladder. In tlie kidney they not infrequently foriii large irregular masses which may till up the entire pelvis of the kidne}' and extend into the calyces, or only small masses may be formed. Con- crements appear in the tissue of the kidney itself in the form of very small masses, which may either lie in necrotic epithelium or in the lumen of the tubules. In the so-called uric-acid infarction of the kid- ney, which is so common in children who die in the first week of life, there is sinij)ly a deposit of urinary sediment in the occluded tubules. The large calculi formed in the urinary l)ladder consist of an organic substance, jjrobably related to albumin, in which various salts are de- jiosited. What sort of material will lie dejiosited in these masses depends upon circumstances. If large amounts of uric acid are excreted, as in the uric-acid diathesis, calculi may form conijio^ed of this. A\nicn there is decomposition of the urine in the bladder, with the jiroduetion of triple phosphates, calculi can be formed of this substance. When a cal- culus has once been formed the irritation which it produces is favorable to its increase. All sorts of foreign bodies introduced into the bladder can serve as nuclei for the formation of calculi. Pigmentation. Many of the normal tissues of the body, both connective tissue and epithelium, contain a certain amount of pigment. The pigment is almost always contained in the cells, and consists of brown or dark amorphous granules. Examples of such pigmentation are found in the iiair and in the choroid of the eye. The nerve-cells in the central norv(nis system contain a small amount of pigment, and pigment is also contained in the cells of some of the glands. The skin may show a general pigmentation, or the pigment is seen only at certain places ; for instance, in the axilla and over the scrotum. During pregnancv the pigment of the skin, especially in brunettes, undergoes a considerable increase. Tiicre maybe a marked increase in the jiigment Ijrought about by certain diseases, as in Addison's disease, in which lesions may be found in the suprarenal capsules or in the semilunar ganglia. The pigment of the heart shcnvs considerable increase in certain forms of atrophv of the myocardium, especially in the atrojihy of old age. Pathological ])igmen- tatiou is also seen in the freckles of the skin and in the congenital pig- 238 SURGICAL PATHOLOGY. nicnted moles. Certain tumors belonging to the sarcomas also show a marked degree of pigmentation. The pigment may be brown or show every degree of transition up to perfectly black masses. It usually lies in the cells, and rarely in the intercellular substance. Wlicn it is found in tile intercellular substance, it is probably due to its being set free by rupture and destruction of cells. The formation of pigment seems to be, in the main, a property of cells belonging to the connective tissue. In the skin, although the pigment may be contained in or between the epithelial cells, it appears to be formed in large branched cells in tiie subcutaneous tissue. The source of the pigment has not been in all eases definitely ascertained. It is true tiiat pigment mav be formed from the blootl-eoloring matter, but hemorrhage is not generallv found in the areas where pigmentation is taking place. The pigment which is derived from the blood under ordinary conditions is usually brown or reddish- brown, and has not the deep-brown or black color found in other con- ditions. Chemical investigation has shown that some of the pigment contains iron, while other pigment is free from it. The blood-extrava- sation which takes j)lace in an ordinary bruise undergoes various changes of color. When the extravasation has taken place in a transparent tissue — for instance, in the pleura or in the peritoneum — a rusty-brown color may remain for a long time afterward. All these changes in color corres])ond to physical and chemical alterations of the hfemoglobin and the iron contained in this. A\'hen hemorrhage takes place in the tissues, the red blood-corpuscles may be takt'n up by the lymphatics in an un- changed condition, or the haemoglobin may be dissolved out of them and taken up by the circulation. It is this dissolved blood-coloring matter which produces the various changes of color in the neighborhood of blood- extravasations. Blood-crystals may bo formed from the exti-avasated blood, and they are frequently found in the remains of old hemorrhages. In cases of chronic passive congestion there is usually a certaiii amount of diapedesis, and a brownish color may be given the tissues by the presence of the blood-pigment. The best example of this is seen in the chronic passive congestion of the lung, the salmon-brown color in this being due to the presence of large cells in the alveoli of the lung, which are filled with brownish-red or brownish-yellow' jiigment. In jaundice or icterus the pigmentation is due to the coloring material of the bile. During life this is easily recognized in the skin and in the conjunctiva. When the jaundice first appears the tissues have a bright-yellow color, and after it has existed for some time this changes into an olive-green or a grayish-green color. Jaundice is usually due to some condition which interferes M'ith the passage of the bile and leads to its absorption into the lymphatics of the liver, and from this into the blood. Swelling of the mucous membrane of the bile-ducts, due to catarrhal inflam- mation, narro^ving or closure of the bile-ducts by cicatrices or by the ])resence of gall-stones, tumors develojied in the bile-duct, or the pressure of tumors outside of the ducts, may all be followed by jaundice. The com- mon bile-duct is comparatively large and thin-walled. The pressure of the bile within it is very low, and a ^•ery slight ilegree of distentii:>n will lead to the retention of the bile and its absorption. Accoi'ding to various authors, there is a form of jaundice, the so-called hsematogenous jaundice, which is produced by the conversion of the haemoglobin of the blood in TUBERCULOSIS AND TUBERCLE. 239 the blood-vessels into hile-coloring matter. The results of experiments have tended to show that a pure ha?matogenous jaundice does not exist, but there niav be a destruction of red blood-corpviscles in the l)lood, and the lueniatoiilin thus set free is converted in the liver into bilirubin and then absorbed. The tissues may also become pigmented from pigment which is taken into the liody from without and absorbed in the tissues. The pigment mav enter the bodv by means of the resjiiratory or intestinal tract and from wounds. In the operation of tattooing the skin is broken and in- soluble cdy. It was ft)und that wherever these nodules apjieared they were eom])osed essentially of the same sort of tissue, and that they were particularly prone to a form of degeneration by which they became; (;hanged into a substance resembling certain sorts of cheese. Tissue of the same general character as the tubercles was also found, not in circumscribed masses, but rather diffusely, and it was found that this tissue also underwent caseation. When inflammation accompanied the process the products also became caseous. There is no douI)t that althouo-h the form of dcgen- eration called caseation is not a specific process limited to the tuberculous tissue, it so commonly takes place in this that it has served more than any other morphological factor to nnite under one head the various manifestations of tiie disease. The conception of tuberculosis as an infectious disease was founded on the anatomical study of the disease and its mode of progression l>efore the discovery of the sj^ecific organ- ism. Even twenty years before the discovery of the bacillus it was found that a disease agreeing in all essential respects with the disease as found in man could be induced in rabbits by inoculating them with the products of the disease from man. It is now universally acknowledged that a bacillus is the cause of the disease. This was demonstrated by Koch in 1881, and all the work which has since been done has served to confirm the work of Koch. The bacillus tuberculosis is one of the .smallest of micro-organisms. It is from one-quarter to one-half the diameter of a red blood-corpuscle in length, and the length is usually five or six times the breadth. The bacilli are usually somewhat bent and the ends are roiuided. Special methods of staining are necessary to demonstrate them. A great many methods have been given, but they all consist in the use of fluids which stain intensely, followed by decolorizing solutions which remove the color from everything but the bacilli. When stained the bacilli may be of a homogeneous color, or they may show an alternation of intensely stained particles and clear spaces. These clear spaces were first sup- posed to represent spores, but it is doubtful whether they should be so considered. It is probable that there is no growth of the organisms outside of the body under ordinary circumstances. Special media and an elevated temperature are necessary for their growth, which is very slow, there being usually no indication of it for several weeks. There is a great difference in the susceptibility of different animals to the dis- ease. Guinea-pigs are among the most susceptible, and these succumb in from six weeks to three months after inoculation. For a long time no typical .structure was regarded as characteristic of tubercle. Virchow described the tubercle as a nodule composed of small round cells similar to those foimd in granulation tissue, and derived from multi])lication of the connective-tissue cells, and called attention to the tendency of the cells in the centre of the nodule to xmdergo necrosis. As the methods of histological investigation improved tubercle was studied more closely, and it was found to have a more or less typical structure. Langhaus gave a more detailed description of certain large multinucleated cells commonly found in tubercle ; a TUBERCULOSIS AND TUBERCLE. 241 peculiar reticulum betweeu the cells was described by other observers. AMieu a very young miliary tubercle is examined after suitable methods of hardening, a reticulum is seen, in the meshes of wliich the cells lie. The extent to which the reticulum is developed depends upon the age of tlic tubei'cle and the character of the tissue in which it develops. It may be as firm and definite as the reticulum of a lymphatic gland, and in other cases scarcely a trace of it may be seen. Tliere are various sorts of cells in the nodule, the most prominent of which from their number are the epithelioid cells. These are cells somewhat resemljling epithelial cells ; they have a pale, finely-granular or homogeneous protoplasm and large oval vesicular nuclei. The arrangement of these cells with refer- ence to the reticulum varies. Sometimes they appear to lie in the meshes of a more or less fibrous reticulum ; sometimes tiiey form the reticulum. The cell-outlines are never clear and distinct ; the cells are usually fused together. The epithelioid cells are also found, not as distinct groujis, but more or less scattered in the tissue. Among the epithelioid cells, lying bet\\"een them or in tlie meshes formed by their union, are round cells similar to those found in young granulation tissue. These cells vary in number, and are most abundant in the periphery of the nodule. The large, multinucleated giant-cells are a prominent feature of the tubercle. Sometimes one of them forms the centre of the nodule, and has long processes which communicate with the reticulum ; or they may be ]K'rfectly round, without processes, and lie in a space surrounded by epithelioid cells. In some cases they are situated in the periphery of the nodule. The nuclei of the giant-cells are either arranged around the periphery, with their long axis perpendicular to the centre, or they are grouped in masses at eitlier end of an elongated cell. The histogenesis of the tubercle has been carefully studied, but we are still far from com- pletely understanding it. Baumgarten considers the ej)ithelioid cells as the most important cells found, and that they are derived from the pre- existcnt cells of the tissue under the influence of the tubercle bacilli. They may be formed from the epithelial cells of glands, fi-oni the con- nective-tissue cells, or from the cells of the blood-vessels. According to Baumgarten, the first step in the formation of a tubercle is the presence of tubercle bacilli in the tissue. These enter into the fixed cells, no matter what the character of these may be, and ])roduce cellular pro- liferation, the newly-formed cells being the epithelioid cells. The pro- duction of the giant-cells is a more obscure process. Weigert thinks that they are prothuK'd by the proliferation of degenerated cells, the nucleus dividing without separation of the protoplasm. In some cases they appear to he produced by fusion of the epithelioid cells, and they are undoubtedly sometimes formed in blood-vessels, and may be traced in continuity with vessels. The}- are probably formed in a variety of ways. The small round cells, found in varying numbers in the tubercle, are derived, like the granulation-cells, from multiplication of the con- nective-tissue cells in tlie tissue in which the tubercle is formed. Little is known of the formation of the reticulum. It is probablj- in large part composed of the remains of the connective-tissue fibres which have been pressed apart by the proliferating cells. It may be in part newly formed by the cells of the tubercle, which for the most part are derived from the connective tissue and under ordinary circumstances would form such tissue. Vol. I.— 16 242 SURCICAL PATHOLOGY. The tubercle is a non-vaseular structure. Tlie blood-vessels wliich are present in the tissue where the tubercle develops become occluded l)y thrombosis or from the pressure of the numbers of cells, and no new blood-vessels make their way into it. This description of tubercle applies to very young nodules in which no ilcgeneration has taken place. The first evidence of such dcii'cu- eration is shown in hardened specimens by the nuclei of the cells in the interior staining less brilliantly. In sections of fresh tissue more or less extensive fatty degeneration of the cells in the centre is found. The nuclei cease to stain, and the cells fuse together in a solid homo- geneous mass in which no cell-outlines can be seen. The form of degen- eration is that described by W'cigert as coagulation-necrosis, and it is always preceded by fatty degeneration. A zone of closely-packed fat- molecules is always found around the necrotic centre. In the giant-cells the same process seems to take place. The centre is similar to the necrotic centre of the tubercle, and around this, just inside the nuclei, there is a zone of closely-packed fat-granules. Macrosco])ically, the tubercle when very young is pale, transparent, and with difficulty distinguished in the tissue. When degeneration begins it is white, opaque, and easily seen. The white color is not due to the absence of vessels alone, but rather to the presence of the fat- molecules. With the appearance of degeneration in the tubercle another cellular element enters into it. This is the polynnclear leucocyte. Necrotic tissue, however caused, exerts a positive attraction on the leucocytes, and the necrotic tissue in the tubercle has the same power. The polynnclear leucocytes may be recognized by their irregularity in form and by the brightness with which they stain. They enter into the tubercle and into the necrotic tissue, often forming a definite ring around the latter. In the degenerated area they seem to undergo the same fate as the other cells. The nuclei break up into fragments and form the small, brightly- staining granules seen in the tissue. Occasionally they may be found within the giant-cells. The fattv degeneration and caseation to which the tubercle is so ]nTinc has been attriliuted principally to tiie absence of blood-vessels. Although this may play a [)art, the degeneration of the tissue cannot be attributed solely to this cause. W'c find other structures in the body, of the same size as, or even larger than, the tubercle, in which there are no vessels and which do not show the same tendency to degeneration. The necrosis of the cells is due more to the influence of the bacilli or their chemical products on the tissue than to the absence of blood-vessels. The relation of the tnlierclc to the surrounding tissue differs. In most cases there is around it a well-marked zone of granulation tissue filled with round cells which become more abundant in the periphery of the tubercle, and finally merge into the surrounding granulation tissue without a sharp line of demarcation. As the tubercle increases in size the central caseation increases in extent and the granulation tissue changes into that of the tubercle, the round cells becoming epithelioid in character. The tubercle mav undergo other forms of degeneration than tlie case- ons. The entire mass may become converted into a perfectly smooth hyaline substance, or, before necrosis takes place, connective tissue may TUBERCULOSIS AND TUBERCLE. 243 be formed from the cells, and such tubercles, even after caseation, are nuieli firmer and harder than tliose in which tiie necrotic tissue is com- posed of cells alone. The number of tubercle bacilli in the tissue varies; they may be present in large numbers or may be absent altogether. As a general rule, thev are not so numerous in the youngest tubercles as they are in those in which degeneration is well advanced. In certain places they seem to be absent as a rule. In acute miliary tuberculosis of tlie liver I have frequently not been able to find a single bacillus in any of the numerous tubercles in the tissue. It is probable that under certain con- ditions thev are destroyed by the tissue, or they may become so changed as to be no longer recognizable. The bacilli occupy no constant position in the tissue.; they may be found within or lying between the epithelioid cells. Sometimes a mass of them may be seen in the centre of the case- ous mass, or the giant-cells may contain them in varying numbers. The miliary tubercles may appear alone, or in numbers forming the large conglomerate tubercles. Most of the tubercles which are visible to the naivcd eye are composed of several nodules united together. These larger conglomerate nodules are formed around a single tubercle which seems to serve as a focus of infection. The tubercle bacilli from this are carried, either by the lymph-stream or enchased in wandering cells, into the surrounding tissue, in which numbers of tubercles are thus, developed. As the caseation in the individual tubercles advances it affects also the tissue lying between them, so that finally a large caseous area is formed which is surrounded by a zone of miliary tubercles. The large solitarv tubercles which are frequently found in the lirain, and less frequenrly in the liver and other parts of the body, are formed in this wav. Although the miliary tubercle is the most characteristic of the lesions produced by the tubercle bacillus, it forms but a small part of the lesions of the disease. The formation of a tissue similar to that of the miliary tubercle, and wiiicii appears not as a nodule, but as a diffuse infiltration of the tissue, is a much more prominent part of the process. The formation of tliis tissue is closely related to inflammation. Where in an ordinary inflammation there would be a formation of granulation tissue, under the influence of the tubercle bacillus a tissue composed of epitlielioiil and giant-cells, and which is peculiarly prone to necrosis and caseation, is produced. In tuberculosis of the joints the pale masses of granulation tissue around tiie joints show on the outside a narrow rim of caseation, and back of this a tissue composed largely of cpitiielioid and giant-cells. In this tissue there are frequently circumscribed tubercles. Not only is the tubercle in its formation closely related to inflamma- tory new formations of tissue, but it is always accomj)anied by inflam- mation. The nodular tubercle as a foreign body excites inflammation around it. The zone of granulation tissue around a tubercle is the result of a reactive inflannnaticm of the tissue. The chemical sub- stances which aj'e produced by the bacilli and in the tuberculous tissue may exert a non-specific but simply injurious action on the surrounding tissue, which will l)c followed l)y infianniiation. The l)acilli themselves, instead of causing the more ty]iical tissue-formations, may excite inflam- mation. The form of inflanunation varies. In some cases an exuda- 244 SURdlCAL PATHOLOGY. tion containing fibrin in v:n ying amounts may 1^<' pnidiiccd ; in otliur cases a typical su]>pnratioii. In no otlicr tissue in tiie body is this inti- mate association witii intlammation so evident as in tiie lungs. Apart from the presence of miliary tubercles, whicii ordinarily ])!ay but a small part in the process, the lesions of pulnKinary tuberculosis are chiefly inflammatory. The gi-eater part of the lesions is due to tuber- culous pneumonia, in which there is consolidation of the lungs, due to exudation and ac(!Umulation of cells in the alveoli. The exudation in some cases contains nuich fibrin ; in otiiers it may be chiefly serous, or the alveoli may be filled witli a hyaline gelatinous substance. The cells witliin tlie alveoli arc chiefly large, jiale, epithelioid cells, mingled witli botli ^^■hite and red corpuscles. In some cases, especially on serous sur- faces, the exudation is chiefly hemorrhagic. Always, particularly in the lungs, along with the inflannnatory ]>roccsscs due directly to the action of the tubercle bacilli and their soluble cliemical products, tliere are inflammatory lesions due to conditions which the l)acilli create. The inflammatory tissue produced in the lungs l\y the l)acilli under- goes the same caseation as the tubercle. It becomes converted into a dry, homogeneous, necrotic mass. The fibrin becomes enclosed in it, and may still be recognized in the caseous tissue by appropriate methods of staining. On microscopic examination of the brittle caseous mass the , anatomical structure of the tissue comjiosing it may still be recognized. In the lung the walls of the alveoli ajipear, dividing the caseous tissue into small areas. The caseation follows the same course as in the tubercle, commencing in the centre and gradually extending to the periphery. An entire lobe, or even an entire lung, may be converted into a solid, necrotic mass of tissue. The caseous tissue docs not tend to remain, but after a variable length of time it undergoes softening. The cause of this is not fully iniderstood. The dry, caseous tissue becomes converted into a soft, fluid, puriform mass. On microscopic examination fragments and detritus of tissue and cells may be recognized, with here and there a few well-preserved leuco- cytes. The cause of the softening may be due t(i changes taking jjlace in the tissue spontaneously or to the action of influences from without. The necrotic tissue forms a favorable seat fi)r the action of otlier micro- organisms which can gain access to it by the bronchi. The softening may be distinctly purulent ; there may be a purulent inflammation in the tissue around it, and the caseous matter may be dissolved in the ])urulcnt exudation. As soon as softening takes place favorable conditions fiir further infection are produced. Not f)uly are the tubercle liacilli ])rcscnt in the softened material, but tliere arc other org-anisms. It is probable that even without the presence of organisms the chemical products pres- ent may exert a deleterious influence on the tissues. Bronchi always open into the softened area, and offer a direct route for infection of other parts of the lungs. To the specific action (if the various substances in the softened tissues must lie added the effects which may be produced by the mechanical action of solid ])articlcs occluding the small bronchi. It is easy to see why in such a tissue as that of the lungs tuberculosis should produce such a variety of lesions. There is probably no disease in which there is such a variety in the lesions as is found in tuberculosis. A careful study of the lung-lesions TUBEECVLOSTS AXD TUBERCLE. 245 iu a case of flirnnie tulicroulnsis would .show nearly all the patholow'ical processes. The course of the disease also varies. In some cases it may advance rapitlly and lead to death in a few months or even weeks ; in other cases it jiursues the most protracted course, may contmue during the entire life of the individual, and in the end only indirectly contribute to death. All of these differences in the effects of infection Avith the bacillus de|)end upon a number of factors. All individuals are not equally susceptible to the disease. It was formerly ii-eni'rally believed that the disease itself was mherited, bnt it is more jVrobable that not the disease itself, but a greater or less suscep- tibilitv to the disease, is inherited. Other things being equal, children of tul)erculous parents, especially if the disease has been in the family for a nund)er of generations, are more liable to be aflected with tulierculosis than the children of parents who were free from this disease. This S])ecial susceptibility or tendency may not be expressed in any other weakness or habit of the body : such children, born of parents in good circumstances of life, may develop strong and robust bodies with more than the average powers of endurance. One factor must always l)e considered — nam^'ly, that in general these children have greater opjior- tunities for infection if they are living in the house with tuberculous people. It is also probable that certain races show a greater susceptibility than others to this disease. In this country certainly the colored and the Celtic races seem to be m(n-e liable to the disease than any other, while the Jewish race appears to possess a certain degree of innnunity against it. The same thing is true of cattle. The cattle coming from the Channel Islands, the Alderney and Jersey stock, especially the pure breeds, have much more of the disease among tlieni than any other breeds. It is probable that there are also differences in the virulence of the bacilli iu different cases. Even inoculations on guinea-pigs of the same age with the same amounts of virus from different sources show differ- ences in the course of the disease. The course of the disease will further be influenced by the manner in which the organisms gain entrance into the tissue. They may enter it bv means of canals or ducts which commimicate with the outside, or by the blood- and lymphatic vessels. In this way either tuberculous iniiannnations or miliary tulierdes may be produced. It is probably not necessary to have an actual lesion of continuity for the bacilli to pass into the tissue. It has been shown that the disease can be produced by rubbing the organisms on the skin of a rabbit. Tuberculosis of the aiimentary canal in man probably takes place without any preceding lesion. The tubercles here a])])ear first in tlie lymj)h-glandular tissue of the gut, and no lesifm of the mucous surface may be visil)le. Not only is there a general difference in the susceptiliility of the tissue of different individuals, but there are differences in the different tissues of the same individual. Some tissues are almost exempt. In certain cases tubercle bacilli may be found in great quantities in the blood, and miliary tuber- cles be formed all over the body, except in the muscles. The ovary shows a relative immunity, and the ])ancreas and thyroid are rather rarely attacked. It canuot be tliat these organs are jirotected from the entrance of the bacilli, f )r in cases of infection by the l)lood they are 246 SURGICAL PATHOLOGY. equally liable to have the bacilli carried into them. None of the tissues enjoy an absolute immunity. Even the muscles may be invaded by the gradual extension of tuberculous foci into them. In a tuberculous uleer of the tongue tubercles are found in the nniscular tissue for :|uite a long distance l)cneath tlu' ulcer. In cases of joint tulicrculosis also the adjacent muscles may be involved by the extension of tiie disease. There is always some primary focus of the tlisease in the body. The primary seat of the disease in most eases is in the lungs, but it may com- mence in almost any other organ of the body. From the primary foens the infection extends, following various routes. There may be infection of the tissues in direct continuity. The bacilli may be carried enclosed in cells, or they may extend by growth into the tissue adjoining, and in this way large tubercuhms nodules may be formed. The bacilli may pass along the lymphatics, either into the surrounding tissue or into the lymphatic glands into which the lymph-vessels empty. The infection of the lymphatic glands almost surely takes place, and in many cases they may jn-esent the oidy evidence of the disease. In tiU)crculosis of the lungs the bronchial glands are always aifected : if the intestine be aflected, the mesentery glands are tul)erculous. In many eases the bacilli are probably carried directly to the lymph-glands from the seat of entry without producing any lesions where they have entered. It is probable that in many eases the bacilli gain entrance into the tissues through the nnicous membrane of the mouth or ])harynx, and the first evidence of the disease is in the cervical glands. The glands appear to protect the organism from further infection for some time. The tissue of the lymphatic glands offers a suitable locality for the growth of the bacilli. Extensive lesions are produced in them, a.nd tinally the glands serve as foci for further infection. The glands next in ordci» become affected, and in this way all the lym])hatics and lyinj)h-glaiids up to the thoracic duct may graduallv become tubercidous ; and finally the l)acilli are carried directly into the bk)od. In most cases the infection follows in the direction of the lymph-current, but it m'ay also proceed against the stream. Infection may also take place by the bacilli being carried along open canals or duets from one ])art of an organ to another or to various parts of the body. The lungs otfcr the most suitable conditions for this mode of infection. The jirimary seat of the disease in most eases is in the apices, and when softening of the caseous tissue takes j)lace the detritus, full of bacilli, may be carried by aspiration into every other part of the lungs. The bacilli are contained in the sputum, and further infection both of the air-passages and of the alimentary canal takes place from this. This mode of infection is seen also in the genito-urinary tuberculosis in the male. Here, in the majority of cases, the ])rimary seat of the dis- ease is in the epididymis. It may be confined to this, or the testicle may be affected by continuity. The e]iidi(lymis is converted into a more or less firm, caseous mass. From this the disease extends along the vas deferens, which becomes enlarged, and on section the interior is found to be lincil with a whitish caseous tissue. In both the vas deferens and epi- didymis the seat of the disease is primarily in the epithelium and takes the form of a tuberculous inflammation.

From the bladder the extension is in a direction opposite to the flow of the secretion. With or withont any involvement of the ureter infection of the pelvis of the kidney and of the adjoining kidney -tissue takes place. It is prolialde that the bacilli And suitable conditions for growth in the ureter, and grow along the walls, just as on the surface of a solid medium, until the pelvis of the kidney is reached. There is no other way for infection to take place from the bladder to the kidney than along the ureter. There is no lymphatic or vascular connection. The proof that this is the usual route of infection in genito-urinary tuberculosis is shown by the certainty with wliicli the lace without the production of a general miliary tul)er<'ulosis. In almost every case of extensive tuberculosis a few tubercle bacilli probably enter into the blood. These will be dcjwsited chiefly in those organs in which the conditions of the circulation are most favorable for the retention of fine solid particles. The liver offers the most suital)lc conditions for this, and in every case careful search will siiow the presence of a few tubercles in this organ. In some cases the bacilli may apparently gain access to the blood without j)rodncing any other lesions. From the primary infection they may in some way gain entrance into the blood and be dejjosited in various organs. In no other way are we able to explain the ]irimary tuberculosis of the bones and other organs into which tiiey could have been carried only by the blood. Of late the theory of congenital tuber'culosis, the result of intra- uterine infection, has received more credence than formerly. Bauni- garten particularly iqiholds tliis view, and explains in this way certain cases in which the infection ij otherwise obscure. In a few cases con- genital tuberculosis has been proven beyond doubt both in animals and in man. The first case in whicli this was siiown was in the organs of a fVetal calf, and careful investigation has shown that this condition is not so very uncommon. Baumgarten found a caseous tubcrcidous noilule in the cervical vertebra of a stillborn infant. Birch-Hirschfeld found tubercle bacilli in a seven months' fretus and placenta removed by Csesarcan sectioti from a mother affected with general miliary tuberculosis. The bacilli were demonstrated both by direct examination and by the inoculation of 248 SURGICAL PATHOLOGY. giiiiic'a-])if!;s. Cases of tuberculosis in infants dying the first few days or weeks after birtli are not so very uncommon, and many of tliese eases sliould be regarded as due to inti'a-uterine infection, (xiirtner lias found that transmission of tultercle bacilli from the inother to the fa^tus is not very uncommon in mice, canary birds, and rabbits. Nor is the infre- quency of tuberculosis in new-born children and infants a conclusive argument aga'nst intra-uterine infection. The infection may take place in intra-uterine life, and the disease remain latent for a number of years. The question as to the frequency of directly inherited or congenital tuberculosis must be consideri'd in connection witli the fact, referred to above (p. 245), that the children of a tuberculous jiarent usually live in a house or room which is more or less infected with the specific bacilli derived from the sputa of the parent, and hence are more than usually liable to contract the disease. GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. ^' By WILLIAM H. WELCH, M. D, INTEirBERS of each of the three groups of pathogenic micro-organisms — bacteria, fungi, and protoztia — may (;ause surgical infeotions. Fungi and protozoa, however, are far less commonly concerned in these infec- tions than are bacteria. In a general consideration of the conditions of surgical infection bacteria are the organisms which require chief atten- tion, so that the subjects to be considered in this article can be appro- priately inchuled under the designation " General Bacteriology of Surgi- cal Infections." Tlie term " general bacteriology " is here used in distinction from " special bacteriology " to designate the general relations of bacteria to surgical infections. It is not deemed necessary in this article to enter into a detailed consideration of the mor})iiological and cultural charac- ters of bacteria. This subject is fully treated in \\x)rks especially devoted to bacteriology. Infectious diseases which require especial consideration by the sur- geon include, on the one hand, many specific infections, such as tubercu- losis, tetanns, glanders, anthrax, and actinomycosis, and, on the other hand, traumatic and other inflammatory and septic infections caused by various widely-distributed bacterial sjiecies. The specific infectious diseases, such as tul)erculosis, tetanus, etc., are for the most part sliarply differentiated by their anatomical and clinical characters, and are caused by micro-organisms which are constantly and exclusively associated witli their respective diseases. On the other hand, the common traumatic infections and other sur- gical inflammations and septic processes do not jiresent eqtially sharp and dcfiniti' differential characters, and aj)parently identical or similar patho- logical processes belonging to this gi'onj) of affections may be caused by various micro-organisms. Thus we do not find in such diseases as septi- cemia, pyaemia, abscesses, osteomyelitis, puerperal fever, or other septic and localized inflammations, or, in general, in the infections of wounds, any single bacterial- species eunstantly and exclusively associated with eacii of tiiese affections, but each disease of this group may be caused by more tiian one species of micro-organism. The etiology of these common septic and inflammatorj' affections presents for our consideration many jiroblems quite distinct from tliose pertaining to the causation of the specific infections. The views now held as regards sources of infection, o])erative ])rocedurcs, and tlie manage- ment of wounds have been developed largely as the I'esult of investiga- tions concerning the relation of bacteria to traumatic infections. 249 250 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. It is important tliat the surgeon should become familiar with the various kinds of bacteria concerned in surgical infeotioris, with their distribution on exposed surfaces of the body and in the outer world, witli tlie ways by which they may cntci' and be (lisciiarge(l IVum the body, witli tile various conditions Mliich favor their invasion and uiulti- ])!ication in the body, with their jiathogenic manifestations, and with the means of combating them. It is proposed in this article to present the more important considerations pertaining to these .sub- jects so for as they do not fall more appropi'iately for their treatment to other sections of this ^\'oi-i<. We shall consider tirst the disti'il)ution of bacteria on ex])os('d sur- faces of the body, liaving especially in view its surgical l)earings. Knowledge of the distribution of pathogenic bacteria is of importance in the study of the causation of surgical infections, as indeed of all infectious diseases. Bacteria of the Skin. There are various questions of surgical interest relating to the bacteria of the skin. The destruction of the surface bacteria both on the hands of the operator and his assistants and over the field of operation in the patient is of fundamental importance in surgical techni(pie. It is important to determine the possibilities of danger from infection by bacteria commonly or occasionally found in or on the skin. Ignorance of the bacterial flora of the normal skin has led some investigators to erroneous interpretations of their observations as to the source of bacteria found in wounds treated aseptically or antiseptically, and as to the presence of supposed specific ]>athogenic bacteria in certain cutaneous diseases. The micro-organisms of the human skin have been studied by several investigators, of whom may be mentioned Bizzozero, Bordoni-Uffrcduzzi, Unna, IMaggiora, Mittmann, Fiirbringer, Preindlsberger, Robb and Ghriskey, and "Welch." As the skin is exposed to contamination from the air and all sorts of sources, it is evident that there is scarcely any limit to the number of species of bacteria which may possibly be found on the skin. Most investigators of this subject have not had the patience or have not thought it worth while to attempt to itlcntify or to describe all of the various kinds of bacteria developing in cultures from the surface of the skin. Mitt- mann mentions seventy-eight different species of cutaneous bacteria, of Avhich fifty-six were cocci. His descriptions, however, are so imperfect as scarcely to serve for the identification of the species. Preindlsberger describes thirty-two species, of which twenty-eight were cocci. Maggiora isolated twenty-nine micro-organisms, of which twenty-two were bacteria, thi'ee budding fungi, and four moulds. ]\Iost of these bacteria are such ' Bizzozero, Virchow's Archii; Bd. iKS ; Bordoni-Uffreduzzi, Fortxchnfte der Medk'm, 1886, p. 151 ; Unna, Monati:hefte J'ilr pnd-liselie Dermntnlogie, 1889, 1S90, 1891 ; Maggiora, Oiornalc delta R.Socktd d'Igiene, 1889; Mittm.inn, Vircliou^s Archil; Bd. 113; Fiirbringer, Desinfektion d.

BACTERIA OF THE SKTX 251 as arc often found in the air oi- on external objects. Cocci are usually found much more abundantly than bacilli in cidtures from the skin. (Jreat variations exist in different cases as to the kinds and the number of bacteria found on the skin. Sometimes one species prcxlomi- nates over the rest, indicating that it has multi})licil and overgrown other bacteria. The conditions in general are not favorable for the growth of bacteria on the surface of the skin, but under the nails and in situations where moisture collects, as in the axillie, the groins, and between the toes, there mav be abundant nudtiplication of certain species of micro- organisms. Altiiough Ixictcria [)rcdoniiuate, budding and mould fungi are often present. The large mmibcr of micro-organisms which accu- mulate beneath the nails is a matter of surgical importance. From a minute particle of material from this situation sometimes as many as two thousand to five thousand colonies develop in culture media, although Usually tlu- number is nuich less, anuration or any trouble. The source of this coccus in asejitic wounds does not seem to be kno\vn to many who have made bacteriological examinations of such wounds; thus.Budingerj^ who examined in 1892 twenty operative wounds which healed by first intention in Bilh-oth's clinic, could not sug- gest any other origin i'nr its presence than the air, and C. Fracnkel- sug- gests that it is lirought to the wound by the blood-current — suggestions W'hich were rendered <|uite unnt'ccssary I)y our previous researches. Although this white e])idermal staphylococcus is often found in w'ounds without any disturban(;e in the process of healing, it may be ' Biidinger, Wiener klin. Woehemidir., 1892, Nos. 22, 24, 25. ^ C. Fraenkel, Baumqarlen' s Jahresberichl, 1892, p. 28. 252 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. the cause of some disturbance, diaractcrized especially by elevation of temperature and moderate sn])puration. This is particularly likely to be the case when there is necrotic or stranjjulated tissue in the wound qv when foreio'ii bodies have been introduced into the wound. It is a com- mon, altiiough not the sole, cause of stitch-abscesses, and it is prone to travel down along the sides of a drainage-tube, and under these circinn- stances may cause the wound to sujipurate. It is often associated with other pyogenic cocci in cutaneous inflammations. We can now under- stand how, without any flaw in the antisejttic technique of the surgeon, tiiis micro-organism may be present in wounds, and we have a satis- factory explanation of the frequent occurrence of stitch-al)scesses. This white skin-coccus is often present in cultures from blood ob- tained by jjuncture of the human skin and in cultures from the sweat after complete disinfection of the surface of the skin. Some observers seem to have supposed that when the stapliylococcus albus is demon- strated under these conditions its presence in the circulating Idood or its excretion by the sweat-glands can be inferred. But it is evident that such an inference is unwarranted without additional proof. There are various other white cocci, and also several species of yel- low cocci, both liquefying and non-liquefying, which are frequently found in cultui'es from the skin. Some of the yellow cocci can readily be mistaken for the sta]diylococcus pyogenes aureus, unless they are carefully studied in culture m(>dia. Tlie staphylococcus pyogenes aureus may be found on the skin, as will be mentioned presently. The kinds and the number of bacteria found upon exposed parts of the skin vary considerably according to the habits and the occupation of the individual. Of especial interest in this connection are the results of the examination of the skin of surgeons and others who come into con- tact with infected persons either during life or at the autopsy-tal)le. We have found only exceptionally the Maph)iIococcux piior/ciics aureus upon the hands of those Mho do not come into proximity to surgical or infected cases, Avhereas we have many times found this micro-organism upon the hands of surgeons, their assistants, and surgical nurses. In examining the hands of those who use corrosive sublimate as a disinfectant it is necessary first to neutralize the sublimate with ammonium sulpiiide, as we have found that tiie sublimate may prevent the development of cuta- neous micro-organisms with which it has come into contact, although it has not killed them ; and this restraining influence may be manifest days, and even weeks, after the application of the sublimate. The length of time that the yellow pyogenic staphylococcus may persist upon the hands varies, and doubtless largely, according to the methods and extent of cleansing tiie skin. It certainly may i>crsist for several days, although it may disappear in a few hours. It does not seem usualh^ to grow down, as does the white epidermal coccus, into the deeper layers of the skin, so that ordinary methods of disinfection of the skin are likely to remove or destroy this organism. By rubbing or by the application of pressure the stajihylococcus aureus may, how- ever, be pressed into the deeper layers, jwrticularly into the liair-f()llicles, and there cause furuncles, as has lieen shown liy the experiments of Garre, Schimmelbusch, Wasmuth, and others. The view which has been advocated by some writers that it requires more thorough disinfection to BACTERIA OF THE SKIN. 253 remove or destroy patliogonie baeteria accidentally or intentionally ap- jilicd to the skin than tt) kill the ordinary liacteria of" the skin is not snpported liy ex])erinieiits. Tiie healthy skin in i^eneral is not a favor- able resting- or breeding-place to secure tlie long persistence of patho- genic bacteria, with the exception of the white epidermal coccus, which possesses relatively little pathogenic power under ordinary circumstances. The stirptocoecm pyogenes has been found less frequently than the staphylococcus aureus in cultures from the skin, and liere too chieHv in cultures from the skin of infected patients or of those who have been in jjroximity to them. It is well to bear in mind that these pvi)genic cocci are not necessarily limited to the immediate neighborhood of an infected wound or focus, but may occur on other parts of the body, as well as in the air or on objects which have been near the patient. Thus Preindls- berger found the aureus in the dirt beneatli tiu' finger-nails of a patient with fracture of tlie femur, and the streptococcus jiyogenes in the same situation in a patient with osteomyelitis femoris for which necrotomy had been performed. The complete disinfection of an infected wound, even if that were possible, would not therefore furnish a guarantee that pyogenic cocci were not present upon the surface of the patient's body in other situations. The hdciUii!^ pi/oeyaneuf! is a common parasite upon the human skin. Miihsam' found it in the axilla and in the anal and inguinal folds of hetdthy persons iu 50 per cent, of the cases examined. Probably local conditions were concerned in these observations, as others have not found this organism upon the healthy skin with such frequency. Al- though tliis organism may manifest importaTit pathogenic activities, its ])resc'uce in wounds is usually made evident chiefly by the green or blue discoloration of the dressings. It was formerly sujjposed to enter the wound from the air, but it doubtless is often derived also from the skin of the patient. The common intestinal bacterium, the hdciUiix co/i commnnls, is of course often present on the skin about the anus. In abscesses in this situation it is often found either alone or associated with otlier bacteria. The colon bacillus may also l)e found ujion the skin in other parts of the body. It is a widely-distributed bacterium outside of the animal body. It has repeatedly been found in wounds in different parts of the body. Skin contaminated with the soil, whicli, as is well known, contains in many situations abundant Itacilli of tetanus and of malignant cedema, is likely to present these micro-organisms. This contamination relates, of course, especially to the hands, and in the case of those who go bare- foot or have holes in their shoes also to the feet. Maggiora M'as able to demonstrate the bacillus of malignant cedema in scrapings from between the toes of a jierson who had walked for half an honr in a garden with a torn shoe. It is not therefore in all cases necessary to sujtpose that the tetanus I)acillus enters a wound from the object which causes the wound, for tiiis bacillus may previously have been attached to the skin. It may in this connection be mentioned that the fseces of herbivorous animals often contain the tetanus bacillus, and in a condition more ' Miihsam, cited by Schimmelbusch, Sainml. klinischer Vortrdge von Vothnann, Serie 3, Heft. ii. No. 62. 254 GENERAL BACTERIOLOGY OF SURGICAL INFECTIOyS. likely to produce tetanus than when tlio bucillus is obtained from the soil. Buday ' has reported a case of tetanus fatal in twentv-four liotu-s which followed the smearing of a wound v.itli fa'ces. The .sintyma /mu-I/Iks may l)e considered in connection with the cuta- neous bacteria. Tiiis l)acterium is usually present in the smegma, and may be found about the penis, scrotum, vulva, and anus. iVttention was first called to this bacillus by Alvarez and Tavel and \)y Mattei- stock in 1886, on account of its resemblance in morphology and staining reactions to Lustgarten's bacillus, which at that time was thftught by its discoverer to be tlie specific cause of syphilis. Greater practical impui-f- ance, however, belongs to the smegma Ixicillus at present on account of the possibility of mistaking it from its staining properties for the tuber- cle bacillus, and there is reason to believe that such mistakes liave been made in examinations of the urine and of secretions or exudates about the external genitals and the anus. The smegma bacillus resembles the tubercle bacillus in th(> ])niperty of rt'taiuing the staining dye after such application of acids and alciihul that all known bacteria except the tu- bercle bacillus, the smegma bacillus, and the leprosy bacillus ai'e decol- orized. This property probably does not inhere in the smegma bacilli as such, but is due to the presence of chemical constituents of the smegma, although this jioint is not positively settled. In the opinion of the writer this peculiar staining reaction does not belong to onlv a single species of bacillus in the smegma, but to several, so that it is more proper to speak of smegma bacilli with this reaction. Mistakes are particularly likely to occur when the handy and popular Gabbet's stain for the tubercle bacillus is emjiloyed. The usual statement is that the smegma bacilli can be distinguished from the tuljcrcle bacillus by less resistance to decolorizing agents, particularly to nitric acid, hydro- chloric acid, and alcohol, also to counter-stains; and tliis often holds true. Nevertheless, smegma l)acilli are sometimes encoinitered ^vhich are as resistant to these decolorizers as are tubercle bacilli. Especial attention should be given to the morphological appearances, as the size and shape of the bacilli often suflice for the distinction, although there is considerable diversity as regards this feature bet\\een the different smegma bacilli which resist decolorizntion. Although smegma bacilli may be present with pathogenic bacteria in lesions around the genitals and anus, they are not known to possess pathogenic capacity. Mau}^ bacteria are attached to the hairs of the body, and particles containing bacteria may readily be detached from the hair. luibb has studied the bacteria which fall off from the hair of the head by move- ment or by combing tiie hair. They are identical with those found on the skin, as might be expected. Haegler has cultivated pyogenic staph- ylococci from the hair of surgeons, and calls attention to the possi- bility of such cocci falling from the hair into a wound or upon objects coming into contact with the wound during an operation. AVriglit has found the diphtheria bacillus on tlie hair of nui'ses in attendance on cases of diphtheria. The cerumen is rich in bacteria. Kohrer - isolated sixteen sjiecies of micro-organisms from the cerumen of fifty cases, but he has not attempted ' Buday, Pester Med.-chir. Pressr, 1894, No. 19. ^ Eohrer, Archivf.

BACTERIA OF EXPOSED MUCOUS SURFACES. 25.5 to identify any of these with prcvious;ly-knowii Imcteria, and his .state- ments as U) tht' existence of patliogenic bacteria in the cerumen are not based upon conclusive observations. Bacteria of Exposed Mucous Surfaces. The wav is open for the access of micro-organisms to mucous mem- bi'anes wliich cover parts wliicii communicate with the outer world through the external oritices of the body. So far as temperature, moist- ure, and the presence of nutritive pabulum are concerned, the conditions are manifestly more favorable for the growth of bacteria upon mucous surfaces than upon the dry skin. These relatively favorable conditions for the develoiMiient of micro-organisms upon mucous membranes are, however, counteracted in large measure by various mechanical and chem- ical influences which prevent the prolonged survival of most of the bac- teria which may enter through the external orifices of the body. There are, however, many bacteria which may multiply, or persist for a long time or indefinitely, upon certain mucous membranes in health, partic- ularly those of the alimentary canal and of the upper respiratory tract, and there are some bacterial species which find their natural home here. Some pathogenic bacteria may live upon certain mucous membranes without doing harm. The study of the bacterial flora of exposed mucous membranes in health and in disease has brought to light many points of surgical interest. CoN.JUNCTiVA. — The bacteriology of the conjimctiva has been inves- tigated bv manv ophthalmologists, of whom may be especially mentioned Fick, Weeks, Leber, Felser, van Genderen Stort, Gombert, Bernheim, Hildebrandt, Franke, Marthen, and Bach.^ When one considers the cx])osed situation of the conjunctiva, it is surprising to find how small is tiie number of bacteria usually pre.sent in the conjunctix'al Sac. Fick found, by microscopical examination of fifty healtiiy coujunctivte, bacteria in only eighteen, aithougii in another series in which forty-nine healthy eyes of paupers were examined bacteria were missed in only six. A negative microscopical examination, however, indicates only that the number of bacteria is small, as then their presence may readily be overlooked without the aid of cultures. As a matter of fact, cultures from the healthy conjunctival sac usually furnish colonics of bacteria. Their number may be considerable, l)ut it oftt'n ha]ipens that not more than three or four colonies develop from a loopful of fluid from the conjunctiva, and it is not very unconmion for culture media inoculated in this way to remain sterile. It is to be assumed that the conjunctival sac ordinarily contains bacteria. The secretion within the lachrymal glands is sterile. Bach describes twenty-six species of bacteria isolated in pure culture from the healthy or diseased conjunctiva. Of these, ten are liipiefying cocci, nine non-liquefying cocci, five liquefying bacilli, one non-liquefying bacillus, and one cladothrix. Ten of the twenty-six bacteria were found to be more or less pathogenic when inoculated into the rabbit's cornea. ' L. Bacli, "Ueb. d. Keimgehalt ties Biiidchautsackes," Archiv f. Ophthalmoloyie, lid. xl. p. 130. This article contains the references to the other articles cited in the text. 256 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. Pink yeast and mould fungi liave also been cultivated fnmi the con- junctiva. Bach considers that of these various bacteria ovAy the staphylococcus pyogenes aureus and albas and tiie strejitococeus jn'ugenes are demon- strated to be pathogenie for man, although the possibility that others in the list maybe pathogenic for man must be admitted. In a few instances the staphylococcus pyogenes aureus, and in more the albus, have been cultivated from the healthy conjunctiva. Cultures of the staphylococcus j)vogenes aureus lune l)een introduced into the healthy conjunctival sac of man and animals withdut causing inflammation. Inasmuch as many micro-organisms must enter the conjunctival sac from the air, the edges of the eyelids, and from contact with the fingers and other objects, and as relatively few bacteria are found ordinarily in cultures from this jiart, it is evident that there must be some very efficient mechanism which rids the conjunctiva of most of the bacteria which enter. There are two principal agencies by which this may be accomplished — namely, mechanical removal through the naso-lachrymal duct, and the germicidal action of the lachrymal and conjunctival secretions. Some investigators have attached the greater importance to the former, others to the latter, of these agencies. Experiments have shown that each may be operative, but the mechanical removal has been shown to be especially efficient and prompt in its action. Van Genderen Stort has made experiments upon raliliits, and Bach upon man, by dropping pure liquid cultures of easily-identified bacteria, such as the Kielwater bacillus, the bacillus coli communis, the staphylo- coccus aureus, into the conjunctival sac, and then determining by cultures the length of time during which they can be demonstrated. Van Gen- deren Stort found after fifteen minutes the inoculated bacteria reduced to a small number, and at the end of an hour they had nearly or entirely disappeai'ed from the conjmictival sac. Cultures from the nose showed that they had been carried down the naso-lachrymal duct, and that after five minutes they were abundant in the cultures from the nasal cavity. Identical results were obtained by Bach in his experiments on human beings. In the experiment of Bach with the staphylococcus aureus, however, which was introduced in such munber that the innnediate plates from the conjunctiva contained countless colonies, there were still seventy-four colonies in the plates made after twenty-four hours. The same experiments' were made after ligation of the naso-lachrymal duct. Under these circumstances the inoculated bacteria also disappeared from the conjunctival sac, but more slowly than when the duct was open. Still, after an hour most of the bacteria had been removed. It was found that they had been carried away by the lachrymal secretion which flowed over the eyelids. If the eyelids were closed by a bandage, the bacteria, with open nasal duct, rapidly passed down into the nose, and they did not appear to pass out between the closed eyelids. When, however, the duct was closed, they appeared aljiindantly in the bandage. Bernheim has demonstrated that the tears possess considerable bacteri- cidal jjower over certain species of bacteria, and his results have been in part confirmed by the experiments of IMarthen, Bach, and others. The staphylococcus pyogenes aureus is killed in moderate number, and the typhoid bacillus in larger number, by the lachiymal secretion. We BACTERIA OF EXPOSED MUCOUS SURFACES. ,257 must therefore assign im|)(irt;uu'e to this chemical action, as well as to the mechanical removal, in ridding the conjunctiva of invading bacteria. Neither of these agencies suffices to remove all of the bacteria. Some bacteria grow reatlily in the fluid of the conjunctiva. As has already been mentioned, the coujuctiva nearly always contains some bacteria. The orifices of tlie Mciliomian glands, the cilia, and tlie edges of the eye- lids usually contain many bacteria, and tliese of course may readily enter the conjunctival sac. Bach was unable to demonstrate that liacteria introduced into the nasal cavity ever make their way up the nasal duct to the eye. It is difficult to obtain complete disinfection of the conjunctival sac. The number of bacteria may be greatly reduced, either by the ai)plieation of antiseptics or bv simple mechanical cleansing, ct)mbined with irriga- tion by an iuditferent fluid, sucli as sterilized salt-solution. Bach obtained the best results by the latter procedure, by which in sixteen outof ibrty- two cases he rendered the conjunctiva sterile. The importance of familiarity with the saprophytes to be found on exposed mucous membranes is illustrated by the history of the so-called xerosis bacillus. Tliis bacillus was discovered by Neisser in 1882 in xerosis of the conjunctiva, and was I'cgarded by liim as the cause of this disease. This C(jnclusiou was adopted by several subsequent investigators, who found this bacillus constantly present in xerophthalmia. This same bacillus has, however, been demonstrated by Schreiber, working under Neissor's direction, in various other affections of the eye, and also, although in small numbei', in the normal conjunctival sac. Neisser has therefore given his assent to the conclusi()n expi'essed by Schreiber:' " Tlie so-called xerosis bacilli are to be regarded as saprophytes whidi ai'e often present in the conjunctiva and its secretion, both in diseased and healthy eyes, and they play no special r6le either in xerosis or in other diseases of the eye." The xerosis bacillus belongs to an interesting group of bacteria which are characterized l)y ri'markal)lc irregularities in size and shape — so-called involution fcjrms — and l)y irregularities in staining, especially by the presence of deeply-staining isolated granules. It is not positively proven to form spores, although some of the isolated granules are interpreted as such by Ernst and by Xeisser. To this same group belong the diphtheria bacillus of Lijffler and the so-called pseudo-diphtheria bacilli. Mouth and Pharynx.^ — All of tlie micro-organisms which may be present in the air, food, and ingested fluids may appear temj)orarily in the mouth. The number of bacteria which have been cultivated ft-om the human mouth is very large. Miller has isolated over one hundred species. Freund has' cultivated eighteen ditterent chromogenic micro- organisms fnim the mouth. It is important to distinguish between the countless bacteria which may appear as transient visitors in the moutli and those which find their permanent home there. \ remarkable peculiarity of the constant inhabit- ' Schreiber, Forlschrilte chr Medichi, 1888, p. 656. ■ Miller, Die Mikro-orijanismen der MundhShle, Leipzig, 1889; David, Les Slicrobes de la linuche, Paris, 1890. These valuable works present the most important results hitherto obtained by the investigators of the micro-organisms of the mouth. Vol. I— 17 258 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. ants of the saliva is that most of tlicm will not t;ru\v in unr artiticial cnlturc nu'dia. This produces often a strikinji' discrepaney between the results of niicroscopieal examination of tiie huceal secretions and those ol)tain((l by cultures. Cover-slip specimens may show an enormous number of bacteria, when cultures made from the same material may show very few or even no colonies. Miller enumerates the following as the constant buccal bacteria : leptothrix buccalin innominata, bacillm buccalw ma.vimus, Upfofhrix Imc- calis 'maxima, iodococcu.s rar/inatuK, xpirUIuut sjiufir/cmnii, xjiirochaic (Jcnlhmi. Xone of these have been artificially cultivated. Uacillus buc- calis maximus and iodococcus vaginatus are stained violet by iodine solution. These bacteria are often present, with others, in carious teeth, in abscesses communicating with the mouth and pharynx, and in exudates on the nuicous membranes of these parts, but they have not been proven to be j)atliogenie. The frequent presence of j)athogenic bacteria in the healthy mouth is of great practical importance. The following patliogenic bacteria have been found repeatedly in this situation : micvococcMS lanceolatm, strepto- coccus pyogenes, staphy/oeorcus pyogenes aureus and albus, micrococcus tctrageuus, bacillus pneituionia: of Friedliinder, bacillus crassus sputigenus of Kreibohm, bacillus coli comnmnis. Biondi, Miller, Kreibohm, Galij)pe, and others have found in the mouth additional pathogenic bacteria in isolated cases, mostly, however, with some morbid condition. The micrococcus lanceolatus was discovered by Sternberg in his saliva in 1880. Many names have been given to this bacterium, the more common svnonvms being di]doeoeeus pneumoni;e, pneumococcus of Fraenkel and M'eichselbaum, diploeoccns lanceolatus, micrococcus of sputum septiciemia, and micrococcus pncumoni;e erujiosa' (Sternberg). This micro-organism was found by Netter in a virulent condition in 15 to 20 per cent., of the healthy persons whom he examined. It varies markedly in virulence, and it is probably present in a non-virulent condition in many eases. Indeed, Kruse and Pansini believe that the micrococcus lanceolatus is a regular inhabitant of the human mouth, although it is present in a virulent state in only alxint one out of five or six persons. As the lanceolate coccus, especially when its virulence is weak or absent, may grow in chains and present cultural characters of the streptococcus pyogenes, it is often difficult, if not impossible, to distinguish between these bacteria. The chief interest attacliing to the frequent presence of the micro- coccus lanceolatus in the healtjiy mouth is that this bacterium is the cause of lobar pneumonia and of many cases of broncho-pneumonia. It may also be concerned in local inflammations of the throat, and as a primary or secondary invader may cause serositis and localized inflam- mations in various parts of the body ; but the streptococcus pyogenes is a more common cause of these lesions. Various virulent and non-virulent streptococci have been foiuid in the mouth, both shoi't-ehained streptococci and long-chained forms, corre- sponding to the two varieties, streptococcus brevis and strejitococcus longus. The distinctions upon which these varieties were established by Von Lingelsheim are often inconstant, and do not serve for a slmrj) differentiation. The chief interest belongs to the presence in the mouth BACTERIA OF EXPOSED MUCOUS SURFACES. 259 and pliaryux of the streptococcus ])yogcnos. Netter found the strepto- coccus p\ogenes in seven out of one hundred and twenty-seven healtliy mouths examined; that is, in 5.0 per cent, of the cases. Dornberger found streptococci iu the mouths of iiealtiiy cliildren in 45 per cent, of the ninety-four cases examined. Widal and Besanjon found streptococci constantly and in large number in the mouths of twenty healthy persons, and still more abundantly in the mouth and pharynx of forty-nine persons aiibcted with varii)us diseases. It often requires a painstaking examination to detect this strcptn- coccus. The colonies are minute and pale gray, and iu a plate crowded with other more striking colonies the former may escape recognition unless es])ecial attention is given to them. If the secretions of the hcalthv mouth and throat be carefully examined both by cover-slip preparations and by agar plate-cultures, streptococci will be found with great frei[uency, if not reguhirly, although, as already mentioned, it is by no means easy to distinguish some of the streptococci from chain forms of the micrococcus lanceolatus. The number of streptococci is increased and their detection is much easier in most inflammatory conditions of the tonsils and pharynx. They are commonly associated with the di]ihtlieria bacillus in dij)litlie- ria, and they are capable of causing all grades of tonsillitis and pharyn- gitis, from slight erythematous forms to pseudo-membranous antl necrotic inflannnations. Streptococci cultivated from the healthy mouth usually have little or no virulence as tested upon animals, and the same is often true of strcji- tococci cultivated from the throat in various infections, local and gen- eral, although in these cases they are more likely to be pathogenic for animals. The stre])tococcus pyogenes is a common and dangerous invader of the deeper air-passages and lungs and of the internal parts of the body. The portal of entry is often the tonsils and throat, and predisposing causes are inflammations and other lesions of these parts, particularly when combined with other infectious diseases and constitutional disturli- ances. Under conditions little understood the mouth-streptococci may acquire enhanced virulence. The influence of predisposing causes as a factor in the etiology of infections is well exemplified by the fact that healthy mucous membranes harl)or very frequently sucli pathogenic germs as the micrococcus lanceo- latus and the streptococcus j)yog<'nes. These bactei'ia often, moreover, cause no serious disturbance in the repair of wounds and injuries involv- ing the mouth and naso-pharynx, although they must gain access to such wounds. Theyare, however, a standing menace in surgical ope- rations involving these parts, a'i.d they may seriously interfere with the healing of such wounds, or may under these circumstances set up pneu- monia and general infection. Staphylococci are found often in the healthy mouth and the throat, but the genuine pyogenic staphylococci do not appear to be present Mitli great fre(juency. Vignal, Netter, and Miller met the staphylococcus pyogenes, aureus only in a com])aratively small number of cases in their bacteriological examinations of the healthy mouth. It is found more frcfpiently in various inflanunations of the nuicous membranes of this 260 GENERAL BACTEIilOLOGY OF SURGICAL INFECTIONS. region, but it plays no such importnut role in these as does the strepto- coccus pyogenes. Wliite liquefying cocci, often described as the staphylococcus pyog- enes albus, are l'(nind oftener than the staphylococcus aureus in the mouth and throat. Some of these have been shown to possess j)yogenic power, and may be accepted as the staphylococcus pyogenes albus, but others are devoid of such power. According to the statements of Biondi, Miller, and others, the micro- coccus tctragenus, which was discovered l)y Koch and Gatfky in a phthisical cavity, is often present in the mouth. In a considerable number of cases examined by the writer it was absent. The frequency with which certain bacteria are present in the mouth probably varies considerably in different regions and according to the class of cases selected for examination. There are various species of tetragenous cocci. The jiathogenic form of Koch and GafFky is designated by Boutron as micrococcus tctragenus septicus. This organism is present more fre- quently in abscesses in the neighliorhood of the mouth and throat, par- ticularly those connected with carious teeth, than in abscesses in other parts of the body, although even in the former it is rarely present. The virulent di])htheria liacillus was found by Park and Beebe ' in the healthy throats of eight out of three iumdred and thirty ])ersons in New York who gave no history of direct contact witli cases of acilhis of Abel" resembles closely the Pricdliinder liacillus, l)ut is believed by him not to be identical with it. AVhcther or not this l)acillus is ever found in the healthy nose is not established. The Friedliinder bacillus and the lanceolate coccus have repeatedly been found in the nose, especially in inflammatory conditions. The rhino- scleroma bacillus is a eapsulated bacillus much liki' the Friedliinder liacil- lus, but differing from it l:>y staining -with (ii'am's method. ^A'e do not at present possess an entirely satisfactory differentiation of a grou]) of eapsulated bacilli to which Fricdliindcr's l)acillus, the ozrena bacillus, the rhinoscleroma bacillus, the eapsulated bacillus of Pfeiffer, and some others belong. The diphtheria bacillus is constantly found in fibrinous rhinitis. Various bacteria, especially dijilococci, have been found in the secretion of corvza. When this secretion is abundantly ]>oured out, it often happens that cultures from several drops of it contain very few colonies or are sterile. Straus has recently made the imjiortant observation that the tubercle bacillus is often present in the nasal cavities of healthy pei'sons who spend much of their time in proximity to tuberculous patients. He examined for tubercle bacilli the contents of the nasal cavities of those engaged about hospital wards containing consumjiti\cs. Twenty-nine such examinations were made by the inoculation of guinea-pigs. In nine cases the guinea-pig developed tuberculosis. Of these nine persons, six were healthy attendants occupied in such work as sweejiing the floor and shaking bed-linen, one was a patient with a chronic nou-tul)erculous ailment, and two were medical students who spent several hours daily in the hospital. None of these individuals presented the slightest evidence of tuberculosis. These observations are even more significant than those of Cornet as to the abundance and wide distribution of tubercle bacilli in the neighborhood of consumptives. Wurtz and Lermoyez have found that the nasal mucus possesses con- siderable bactericidal capacity. Von Besser found bacteria abundantly in the larynx and bronchi of human corpses, but he demonstrated that after death the fluids from the mouth and naso-pharynx may readily penetrate even into the smaller bronchi, and moreover in his cases the lungs and air-passages Mere dis- ' Paulsen, Cenlrolhl. f. Bitkter., Bd. viii. p. 344. '^ Abel, ibid., Bd. xiii. )i. 161. BACTERIA OF EXPOSED MUCOUS SURFACES. 2G3 eased ; so tliat lie attaches no importance to his observations as hearing upon the question of tlie presence of bacteria in tlicse parts in iiealtli. Hihli'!)ran(lt ' found tiiat culture media inocuhited witli l)its of the huig- and of traelieal mucus from recently-killed rabl)its usually remained sterile, and he concludes that practically all bacteria which enter with the air are retained in the upper air-passages and do not penetrate below the larynx. This protection, however, has its limits, as when the inspired air was loaded with fungus-spores these could l)c demonstrated after half an hour in the lungs. That foreign particles in the air may be conveyed into the lungs is evidenced by the coal particles regularly found in the lungs. Wargunin, in opposition to Hildebrandt, isolated nine different kinds of bacteria from the trachea, bronchi, and lungs of recently-killed healthy animals. The observations of the writer are in harmony with Hildebrandt's results as to the usual absence of Ijacteria, at least in sntticient number to be demonstrable by ordinary culture metliods, in the bronchi and lungs of healthy animals. At autopsies on human beings bacteria, including the micrococcus lanceolatus and the streptococcus pyogenes, may be found in tlic lungs withiiut notie(>able lesion of this organ. The action of the ciliated epitlielium and coughing would tend to drive out bacteria which may have entered the trachea and bronchi. The expired air is free from micro-organisms, except as these may be mechanically detached, as in sneezing or coughing. ^\'e are not informed as to the frequency with which bacteria are ])resent in tiie healthy tymjianic cavity. That bacteria may pass up the p]ustacliian tube into the middle ear is shown by the presence in otitis media of various micro-organisms often finuid in the mouth and naso- ])harynx, notably the micrococcus lanceolatus, the streptococcus jiyogenes, the Friedliinder bacillus, and the pyogenic staphylococci. There are of course other paths by which micro-organisms may be carried into the middle ear, as the lymphatic and l)lood-currents, and in meningitis from the cranial cavity. Netter found constantly in the middle ear of new-born infants, at au- topsy, bacteria, and among these were pathogenic forms to which he attrib- utes the frequent occurrence of middle-ear inflammations in infants. In autojisies upon one hundred and eight infants less than one year old H. Kossel found otitis media in eighty-five cases. The most common organism in these cases was a delicate bacillus, apparently identical with Pfeifl'er's pseudo-influenza bacillus (38 cases). In addition were found the diplococcus pneumonia (10), streptococci (4), thick bacilli (2), staphy- lococci (2), and the bacillus pyocyaneus (once). One case was tubercu- lous otitis. Some writei's are of the opinion that changes often found in the middle ear of the new-born are jjost-mortem alterations. Stomach and Intestine. — The study of the micro-organisms present in the stomach and intestine presents many jjoints of physi- ological and jKVthological interest, but we must confine our attention chiefly to those of surgical interest. When we consider the relations of intestinal bacteria to various surgical aflections, suc'h as perforative and ' Hikleljrandt, Zieyler's Beitrdgc, Bd. ii. 264 CKXERAL BACTERIOLOGY OF SURGICAL INFECTIONS. ((tlier forms of peritonitis, apjjciidicitis, and even infections remote from tlu' intestinal canal, it is apparent tiiat this sulyect claims the attention of the snrgeon. The main sonrces of the micro-organisms of the stomach and intes- tine are the inu^esta and the air. From tliese sonrces cc^nntlcss bacteria and ftuiii'i of all kinds arc introduced into the alimentary canal, l)nt, as is tnic of other exposed mucous surfaces, only a limited number of species are capable of prolonged existence in this situation. The meconium of the new-born infant is sterile, but within twenty- four liours after birth it usually contains abundant bacteria. Although many varieties of bacteria may be found, Eschcricii has demonstrated a constant bacterial flora in the lleccs of milk-fed infants. These con- stantly-present intestinal bacteria are the bacillus lactis aerogenes, pre- dominating in the small intestine, and the bacillus coli communis, pre- dominating in the large intestine. These bacteria remain throughout lite as the obligatory and characteristic intestinal bacteria of man in health, and as tiiey are frequent seccmdary invaders of the body in disease, and may be concerned in various surgical and other diseases, much practical interest attaches to them. The bacterial flora of the small intestine, particularly in its upper part, is more varied, as tested by jilate cultures, than that of the large intestine. In fact, the comparison of the results of microscopical exam- ination and of cultures from the stools indicates that a large number of the bacteria in the fseces are dead. As there is very little free oxygen in the intestinal canal, the con- ditions are not favorable for the multiplication of obligatory aerobes. Most of the bacteria found in the intestine are strict anaerobes or facul- tative anaerobes, but anthrax sjiores, which re(juire oxygen for their germination, develop into l)acilli in the intestinal canal. It is certain that patliogenic l)acteria of many kinds often find their way into the intestinal canal ; in fact, there is ])robably no pathogenic germ which may not in certain individuals and in certain times and. places be present in the intestine. It is true that the acid gastric juice may kill many of the micro- organisms which enter the stomach, but there are many which resist its action. If we were to rely exclusively ujjon the results of experiments in the test-tube on the germicidal action of the acid gastric juice, particu- larly the very acid juice of some animals, we should consider this action a formidable obstacle to the passage of living bacteria into the intestine. But when we consider the insusceptibility of many bacteria to weak acids, the relatively slight and varying acidity of the human gastric juice, the absence at times of any acid in the stomach, the withdrawal in large measure from the direct and concentrated action of the gastric juice f>f bacteria contained in ingested masses of food and large volumes of fluid, and the I'apidity with which the gastric contents may pass into the duo- denum, we can understand how micro-organisms, even those very sus- ceptible to acids, may find fre(]ucnt ojiportunity to enter the intestine. Only a fraction, usually not more than .05 to .1 per cent., of the total acidity of the stomach is due to free hydrochloric acid, and the proteid hydrochlorides possess very little bactericidal power. Many organisms can grow in the human stomach even when it is very BACTERIA OF EXPOSED MUCOUS SURFACES. 265 jiciil, as has been shown by Gillespie.' The nunil)er and variety of niicro-org-anisins whieh have been isolated from tiie luinian stoniacli by Maefadyen, Al)elons, Ojipler, (Jillespie, and others are very great, but it wonld serve no useful purpose to enumerate them liei'e. The liaeilhis lactis aerogenes, tlie baeillus coli eommunis, and the pyogenic cocci may be specified as having been repeatedly found in the healthy stomach. The list of pathogenic bacteria which have been found in the intes- tinal contents is a long one. Many are present only accidentally and as a transient phenomenon. Some are f()und with such frecpicncy as to merit special notice. In general, the conditions are not favorable for exten- sive multiplication of most pathogenic micro-organisms in the healthy intestine. Pyogenic cocci are rarely absent from the intestine. They are often present in such small number as to escape detection, but the great frcqueni'y with which these cocci, particularly the strcj)tococcus jivogenes, are found in the exuilate of perforative jjeritonitis, where they can rapidly multiply, shows that they are common inhabitants of the intestine. Gessner found a pathogenic streptococcus, probably identical with the streptococcus pyogenes, in large numbers in the duodemnn of six persons out of eighteen examined at autopsy. The bacillus pyocyaneus and the proteus bacilli are also often jm'sent in the intestine. The tetanus bacillus and the bacillus of malignant cedcma are regidar inhabitants of the intestine of herbivorous animals. The micrococcus lant'eolatus has been found repeatedly in the human intestine, likewise the bacillus pyogenes foetidus. The bacillus aerogenes capsulatus has been found l)y the writer in the intestine in two cases of perf)rative peritonitis with |)rodnction of gas. The occurrence of intes- tinal actinomycosis and of perityphlitis actinomycotica shows that the actinomyces may find its way into the intestine. There are various other pathogenic bacteria which have been occa- sionally found in the intestine, but those which have been mentioned ai'e the ones of chief surgical interest. The specific intestinal infections of typhoid fever, cholera, tuberculosis, and antiirax are not considered here. The amceba dysenteri;e, on account of its relation to abscess of the liver and lungs, deserves mention. In this connection it may be stated that the bile in the normal bile- ducts and gall-bladder is to be regarded as free from bacteria. Under various conditions, however, the colon bacillus and other Ijactcria, par- ticularly the ]>yogenic cocci, often wander into the biliary passages. The M'riter has found very frequently the colon liaeillus in cultures made from the interior of gall-stones. It is not uncommon at autopsies to find the colon bacillus, less .frequently pyogenic cocci, particularly streptococci, in the bile without any alteration in the bile or evident lesion to exjdain the migration of these bacteria. Contrary to an old idea, the bile has not been found to possess any decided germii'idal property, at least as regards most bacteria.

These are abundant and varied in the fossa navi('uhiris, and raetically sterile, but that if the bullets become contaminated with pathogenic bacteria, the latter are not destroyed in the discharge and transit of the bullet, and are capable of infecting wounds. He was able to infect rab- bits with the streptococcus pyogenes and other jiathogenic bacteria by firing infected bullets through the ear. As compared with contact infection, infection of wounds from the air is of minor importance, but surgeons are not agreed as to whether or not the dangers of air infection are so slight under ordinary conditions that they need not be taken into consideration at all. In the early days of antiseptic surgery bacteria of the air Mere thought to be frequent agents of wound-infection and the carbolic s]iray was introduced Ijy Lister with the intention of destroying them. There followed a period when sur- geons considered that the air bacteria could be wholly neglected as a source of traumatic infection, and this is probably still the opinion of the majority of surgeons. At present there is a tendency again to pay more attention to the possibilities of infection from this source, and some sur- geons have even gone back to the use of the spray. Bacteria are always present in the air over the ground and around human habitations, whereas sea-air at a considerable distance from land ' La Garde, New York Medical Journal, Oct. 22, 1892. SOURCES OF THE BACTERIA IN SURGICAL INFECTIONS. 277 and the air at high altitudes is nearly or quite free from micro-organisms. Bacteria do not usually occur in the air as single, detached cells, but ratiicr as clumps attached to particles of dust, so that in a perfectly quiet atmosphere, as in a closed room, these particles containing bacteria rapidly settle upon underlying objects. Bacteria, being thus attaclied to particles of dust, are readily filtered out from the air by passing it through porous substances, such as cotton-wool. The bacteria are car- ried down by drops of rain, and the air of a room may be freed from floating bacteria by producing an artificial rain by some form of douche or s|)ray a[)paratus. Whatever creates dust, such as tlie entrance or exit of a body of students, and other movements in a room, brings bacteria into the air. It is a fact of fundamental hygienic importance that fine particles, including bacteria, are not detaciied from moist surfaces even by strong currents of air. Hence conies the iiygienic value of using moist cloths in removing dust and in cleansing a room. Substances containing infected material sliould not be allowed to dry under conditions in whii'h dust therefrom can be conveyed into the air. In the present era of dry dressings for wounds there is frequent opportunity for the scatter- ing of dust from the discharges dried on the dressings in the removal and snbsecpient handling of these dressings, unless especial care be tid^en to pi-event this in all cases where pathogenic bacteria may be present. Tlie number of bacteria in the air varies greatly under different con- ditions. In general it may be said that living micro-organisms are less abiuulant in the air than was formerly supposed. They cannot multiply in the air, and only those whose vitality is not destroyed by drying can exist in the air. Desiccation may lessen the virulence of pathogenic bac- teria without actually destroying them. Wiiat interests us chiefly in this connection is to know whether patho- genic bacteria, and more particularly tiie pyogenic cocci, occur in the air, and, if so, how frequently and under what conditions. Pyogenic staphylococci and strejitococci have been repeatedly found in the air, althougli generally only in small number. Olttaincd from this .source, these cocci are often of only sligiit virulence, but highly virulent sta])hylococci and streptococci have been isolated from the air. Among those \vho have isolated pyogenic cocci from the air may be especially mentioned von Eiselsberg, Emmerich, Neumann, Prudden, Ullmann, Ilaegler, C. Fraenkel. Haegler ' demonstrated that streptococci may j)reserve their vitality and power of development for at least thirty- six days, and staphylococci for one hundred days, in pus dried on bandages. Pyogenic staphylococci and streptococci have been found far more frec|uently in hospital wards and operating amphitheatres than else- whei'c. Haegler found stajihylococci and streptococci in the majority of his examinations of the air in the wards antl operating-rooms of the hospital in Basle, and tlie number of such cocci present was in general proportionate to the opportunity for entrance into the air of cocci from dry material and to the amount of stirring uji of dust by movement in the room. He also detected in a number of instances the bacillus pyo- ' Haegler, Beiirdge zur klinischen Chirurgie, Bd. ix. p. 496. 278 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. cyaneu.s in tlic air. Streptococci have been found frequently in the air of rooms containing cases of erysipekis. Haegler foiUKl the pyogenic cocci on the hair antl coats of surgeons, and in cobwebs in hospital rooms, as well as on other objects. He con- cludes from his investigations that the danger of infection from (he air is greater than is assumed by many surgeons. Schimmelbusch and some other investigators have found pyogenic cocci very rarely in surgical wards and operating-rooms. It is suf- ficiently apparent that various circumstances, such as the care exercised in the destruction or sterilization of material infected witli discharges, the use of disinfectants, the isolation of infected cases, and the observ- ance of strict cleanliness, must influence the results of these examina- tions of the air of hospitals, and that tlie danger of air infection may be cousideral:)le in one place and reduced to a minimum in others. Air infection may readily become contact infection by bacteria from the air being deposited upon the hands of the operator or his assistants, upon instruments, dressings, or other objects which are brought into contact with the wound. jMicro-organisms which are capable of develojinient only within the living body are called obligatory parasites. A facultati\'e parasite is one whose or'dinary mode of life is .saprojjhytic, but which is capable of a parasitic existence, and a facultative saprophyte is one whose ordi- nary existence is parasitic, but which can grow outside of a living host. These distiuotions, however, cannot always be sharply carried out in practice. Although we can cultivate the gonococcus outside of the body in specially prepared artificial media, there is no reason to suppose that it multiplies, or even long survives, in the outer world under ordinary conditions, and immediate contact with the infected person is the princijial source of infection. The tubercle bacillus also can he cultivated arti- ficially, but conditions must be excejitional which permit its nudtiplica- tion outside of the body. Unlike the gonococcus, the tubercle bacillus is capable of prolonged survival outside of the body, and, as is well known, it is a widely-distributed organism. The leprosy bacillus has not been cultivated artificially, and it is ranked among the obligatory parasites. Intimate contact with an infected person seems to lie the usual source of infection, although opinions are divided as to the mode of transmission of this disease. The micro-organisms causing syphilis and hydrophobia are unknown, but they are doubtle.ss obligatory para- sites. The bacteria causing anthrax, tetanus, malignant oedema, and actino- mycosis are facultative parasites. The jiyogenic cocci find the best con- ditions for their multiplication in the living body or material rich in organic matter, but these ubi(|uitous bacteria can often find natural opportunity for multiplication outside of the body. The only bacteria infectious for human beings which are positively known to develop spores are the bacilli of tetanus, anthrax, and malig- nant oedema, all killed by exposure in a moist condition for a few minutes to boiling temjieraturc. It is generally stated that the tubercle bacillus forms spores, but this is not positively demonstrated. There is still greater doubt as to the formation of spoi'cs by the bacilli of gland- ers, typhoid fever, and lej)rosy. The tubercle bacillus, the pyogenic POBTALS OF ENTRY OF BACTERIA IN SURGICAL INFECTIONS. 279 cocci, and the typlioid bacillus are among the more resistant bacteria which are not proven to form spores. Portals of Entry of Bacteria in Surgical Infections. The portals of entry or atria of infection are the skin and the exposed mucous membranes of tlie respiratory, alimentary, and genito- urinary tract, and wounds of these surfaces. The fcctus may become infected either by germinal, or far more frequently by ])lacental, trans- mission of infectious micro-organisms. In our lalroratory experiments we rarely imitate the precise conditions of natural infection, but we malce fre(pient use of methods of inoculation which occur only excep- tionally or not at all under natural conditions, such as the injection of bacteria directly into the vessels, into the serous cavities, and beneath tile skin, and forced inhalations of large numbers of micro-organisms. Most of the hatttcria concerned in surgical infections are capable of entrance tlirougli any portal and of pniducing inl'ection in any part of the body, but there are some which are restricted to certain modes of entrance and to certain parts of the body. Examples of the latter group are the bacteria causing gonorrhea and tetanus. Let us consider briefly the defensive arrangements which exist nor- mally at the various pt»rtals of entry. These are jiartly mechanical, and due to the anatomical structure of the ])art. The thick epidermal cover- ing of tlie skin and orifices of the body is impenetrable to most bacteria. The thick layer of laminated flat epitlielium covering the mucous mem- branes of the mouth, esophagus, and vagina is a hardly less efficient mechanical protection. The more delicate raucous membranes covered by cylindrical epithelium are so situated as to be less exposed to injury, but even tiiese surfaces do not ordinarily permit the penetration of l^ac- teria witiiout the occurrence of some damage to their integritv. The ciliated epitlielium of the respiratory tract drives foreign particles toward the natural outlets. The tortuous arrangement of the upper air-passages filters out most of the bacteria which are inhaled. Bacteria which may iiappen to enter the bladder or uterus or the glandular ducts, such as the salivary, Ijiliarv, or pancreatic, which are normally free from bacteria, would be likely to be discliarged with the secretions. Obstruc- tion of these ducts predisposes to their infection. There are certain situations, particularly the tonsils and the lymphatic follicles of the intestine, M'liich, by the delicate nature of their covering, are especially exposed to tlie invasion of bacteria. These are vulnerable parts, as is sliown Iiy the frecpiency with which primary and secondary infections start froui them, but there is reason to believe that the Ivm- phatic tissue in these situatioi.s is richly endowed with vital jirojierties hostile to the development of bacteria. Of equal importance with these mechanical defences arc the anti- bacterial properties of the secretions on mucous membranes. These properties depend partly on the chemical reaction (gastric juice, vaginal secretion), jiartly on the antagonism offered to invaders bv the regular bacterial flora of the surface, but mainly upon bactericidal qualities at present little understood as to their cause, but unquestionable as to their existence. 280 GENERAL BACTERIOLOCrY OF SURGICAL INFECTIONS. Mi('ro-()i-i;aiiisins find at tlie fratos of entrance livin<>- cells and fluids which in healtJi are capable of destroying many of them, and if thcv pass these gates, it is usually only to be arrested and destroyeil at the nearest lymphatic glands. Xor are these j)rotective agenci(>s"liniited to the lymi)hatics or to any jiarticular organs : they are present in the blood and everywhere througjiout tiie living body, altliougli more highly devel- oped in some places than in others. Whether the battle against the invaders be within the cells, as is assumed in the phagocytic theory, or outside of the cells, the weapons of attack must be furnished bv" the cells. The living body is amply protected in health against all ordinary bacteria which may seek entrance, and the study of the etiologv of infec- tious diseases involves the consideration not oidy (if the characters of the specific agents of infection, but also of the ways in which the natural defences of the body have been overcome. There are infectious micro- organisms to which the healthiest and strongest body is able to offer no resistance, and there are other micro-organisms which are I'ajiable of doing harm only -h hen tlie vital resistance of the body has liecn lowered. Can micro-organisms penetrate the intact skin or mucous membranes, or must there always be some jtathological change or lesion of continuity of these parts to permit their entrance ? This question has been variously answered, but, at least as for as certain membranes and certain micro- organisms are eoncerned, the evidence must be regarded as conclusive for the affirmative answer. It cannot be doubted that the infectious agents causing malaria, relapsing fever, and the eruptive fevers may enter tlie body without any defect in the skin or mucous membranes, but our concern is not with this class of diseases. Garre,' in 1885, was the first to make a self-sacrificing experiment which has since been rejieated \\ith similar result In' several others. He rubbed into the skin of his fu-earm, in the same way as one \\-ould rub in an ointment, a large quantity of a virulent culture of the staphylo- coccus pyogenes aureus. The skin was left intact. After six hours a prickling sensation, associated ^ith redness and turgescence, developed, and in a few hours more about twenty pustules, each developing about a laimgo hair, had formed. In the course of four days an extensive carbuncle, which discharged pus through seventeen openings, formed, and the axillary glands were swollen. The largest numlicr of experiments of this character have been by Wasmuth.^ The experiment succeeds almost invariably when virulent staphylococci are thoroughly rubbed into the human skin, but fails almost constantly to give a positive result ujion the skin of animals (rabbits, guinea-pigs). The failure with animals is not due to greater impenetrability of their skin to bacteria, for anthrax bacilli and some other pathogenic bacteria when rubbed into the skin of animals are capable of causing infection. Animals are less susceptible than man to these pyogenic cocci — a fact which should not be lost sight of in draM'- ing inferences applicable to man from experiments upon animals with these organisms. Biidinger has shown that pyogenic cocci nearly devoid of virulence for animals may produce abscesses when rubbed into the human skin.

PORTALS OF EXTRY OF BACTERIA IN SURGICAL IXFECTIOyS. 281 The mere application of tlie ijaeteria to the siirflice of tlie skin i)ro- duccs no infection either in man or animal^;. The bacteria must be well rubbed in or pressed in to cause infection. Throuiiii wiiat channels do the bacteria penetrate the skin in these experiments? There are tlu'ce possil)ilities — namely, through the epi- dermis into the rete Malpighii, into tiie sweat-glands, or into the hair- follicles and sebaceous glands, yciununelbuscli, Machnoif, and Wasnnith have demonstrated that they enter by way of the hair-follicles, and the last-named author considers that they can enter the intact skin in no other way. He finds a principal support for this view in the fact that he was unable to produce any effect l)y rubbing the cultures into the skin of the ball of the thuml), where there are no hair-follicles, and in the actual demonstration liv himself and previous experimenters of the bac- teria in the hair-follicles. This conclusion is in accord witli the clinical fact that furuncles form almost exclusively in parts of the skin provided with hairs and sebaceous glands, and often begin as pustules around the hairs. The ol)jection mav be raised that these ex])eriments do not actually prove the possibility of infectious agents penetrating the intact skin, as microscopical lesions may be caused by tlie rubbing or the }3ressure. Macroscopical and microscopical examinations, however, failed to show any lesion of the epidermis. Still, a microscopical defect might be diffi- cult to detect, and Schimmelbusch considers it possible that in these experiments a minute Ijreach of continuity may be produced. As experiments uj)on rabbits with bacilli of anthrax and of rabliit septictemia have shown, general as well as local infection may follow the rubbing of certain pathogenic bacteria into the skin. These experiments simplv show that certain pathogenic organisms are capable of settling in the iiealthy skin and causing local infections, which may, however, be the starting-point of general infections. They do not show that micro- organisms can pass through the healthy skin and thence invade the body witliont jiroducing any damage at the point of entrance. It is a well- known clinical fact that in wounds this local damage may be very slight and readily overlooked. Indeed, there is a certain antagonism between the extent of the local infection at the point of invasion and the likeli- hood of general infection. We have no conclusive experimental evidence that bacteria can enter the circulation through an intact mucous membrane without causing any lesion whatever at their point of entry. There are, however, many ex- amples of ]iathogenic bacteria which are cajmble of attacking a healthy nuu'ous membrane and of ])roducing local and general infection through this cluuMiei. The lesion of tlie mucous membrane in some of these cases maybe slight and not. readily demonstrable. The gonococcus is certainly capable of infecting an intact mucous membrane. A large number of infectious diseases can be produced by feeding cultures or material con- taining certain pathogenic bacteria. Examples of such intestinal infec- tions are tuberculosis, anthrax, typhoid fever, Asiatic cholera, hog cholei'a, and chicken cholera. As has already been mentioned, the points in the alimentarv canal most vulnerable to infection are tlie tonsils and the lymphatic follicles. As is well known, indifferent foreign particles, such as coal-dust, may 282 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. be taken up from tlie air-cells ni' tlie liiiijis and eonveycd by the lymphatic current to the broneliial lym])liatie liiands, but under normal conditions these ])artieles do not enter tlie ti'eneral cireulation. It is ])robable that bacteria maybe disjiosed of in tlie same way. It is said that some of tlie bacteria of the septicsemias of animals — as, for example, the bacillus of rabbit septicaemia — may enter the circulation through the lungs without leaving behind any manifest lesion. We have no conclusive evidence that the mieroeoeeus lanceolatiis, the streptococcus pyogenes, or the other pyogenic bacteria can ])ass through the intact lungs into the general cir- culation without causing some intlammation of the lungs. The lungs possess the power of disposing of many pathogenic bacteria which have been introduced into tiiem. There have been many experi- ments made to determine the ]M)Ssibility of infection with anthrax bacilli bv way of the lungs, and the conclusions drawn from them hav(> been wiite of amputation of tiic tail ten mimites after the inocnlation. Nissen found anthrax bacilli in the neai-est Ivm- phatic glands within one hour and a half after peripheral inoculation of an extremity. The application to smooth fresh wounds by Schini- mclbusch of a moderate tjuantity of a culture of the anthrax bacillus or of a streptococcus lethal to mice was fatal, notwithstandinii- an innne- diate attempt at disinfection of the wonnd witii the strongest antiseptics, ychimmclbusch and IJicUer' were able to demonstrate in cultures from tiie internal organs (lung, liver, spleen, kidney) anthrax bacilli in an hour, or even half an hour, after the incjculation of fresh wounds of mice with this organism. They showed that this rapid absorption of bacteria from fresh bleeding wounds applies equally to pathogenic and sa]n-o])hytic bacteria. In cultures from the internal organs mad(> five mimites after the infection of a fresh wound of a rabbit's thigh with the bacillus jjyocyancus they found many colonies of this bacillus. In making the cultures it is necessary to use the whole organ finely divided. The significance for the individual of the rapid absor])tion of bacteria from fresh wounds depends, of course, primarily, uixm the character of the bacteria. If these in small or moderate number are cajjablc of causing fatal septicemia, as is the case with virulent anthrax bacilli in highly susceptible animals, the issue is necessarily fatal ; if, as is the case with the pyogenic cocci, the bacteria do not readily gain a foothold where they can multiply, their absorption is of little consequence in most cases, and, so far as the ordinary saprojihytes are concerned, their aljsorption from fresh wounds is a matter of indifference. The period during which this rapid absorption of bacteria from a fresh wound takes place is of short duration. As soon as a coagulum has formed on the surface of the wound and the open mouths of the lymjihatic and blood-vessels are plugged, the conditions are changed, and fine particles like bacteria are no longer (piickly transported into the lymj)hatic and blood circulation. The surface of a healthv granulating wound ofiiers great resistance to the invasion of bacteria, almost as nuich as an intact exposed surface of the body. Slight injuries, however, such as probing, the removal of dressings, and other manipulations, may con- vert a granulating surface into a fresh wound, with the accompanying dangers of infection. Elimination of Bacteria in the Secretions. In former times it M'as thought that the body gets rid of infectious agents chiefly by their excretion through the eniunctory channels. We now know that micro-organisms ai'e destroyed within the body by the living cells and fluids, and that this method of freeing the Ixidy from living bacteria is far more efficient and of much greater importance than that of their excretion by the cmiuictorics. Pathogenic bacteria often appear in the secretions in various infectious ' Schimmelbusch, Deutsche med. Wochemchrift, July 12, 1894. ELIMINATION OF BACTERIA IN THE SECRETIONS. 285 diseases, and it is of interest to know under what conditions they are excreted and in what secretions they occur. The mode of conveyance of infectious organisms from an infected individual to others, and the practical measures of prevention, are determined in large measure by tlie manner of elimination of these organisms from the infected body. Wyssokowitsch, as the result of a long series of experiments, came to the conclusion that bacteria in the circulation are never discharged from the body through the healthy organs, but escape only through some breach df continuity or other lesion in the excretory membrane. Hence those pathogenic bacteria which cause some damage to the excretory surflices — and there are many such bacteria — arc most likely to appear iu the excreta, although bacteria without this capacity may escajjc through lesions preforuied from other causes. Not all subsequent investigators of this subject have been able to con- firm this law of Wyssokowitsch, aud it is true tliat l)actcria may be elimi- nated from the circulation Ity way of tiic excretions without demonstral>le lesion of the organ tlirough whicli they liave passed. It is to be remem- bered, however, that the lesion may be difficult to detect, or may be of some such undemonstrable character as that of the vascular walls in inflammation which permits the passage of leucocytes and red blood- corpuscles. There ha\-e been many special and incidental investigations of the subject of the escape of bacteria ^vith the secretions. Of the experimental investigations relating to the subject in general the most important are those of Wyssokowitsch, Pernice and Scagliosi, and Sherrington.' Sherrington experimented on mice, rabbits, and guinea-pigs by the subcutaneous or intravenous iuoculation of eleven, mostly pathogenic, species of bacteria. In sixty-eight observations the presence of the .specific micro-organisui introduced was detected in the urine twenty- one times ; on eight of these twenty-one occasions the presence of blood in the urine was ascertained by the spectroscope ; and in a ninth case gross lesions (tubercle) were found in the kidney. Sometimes the urine contained much coagulable albumin. Of the bacteria of surgical im- jjortance tested, tlie stapliylococcus aureus, the bacillus pyocyaneus, the bacillus anthracis, and a bacillus jirobaljly identical with the Friedliinder bacillus were found frccpicutly in the urine. In Ibrty-nino experiments the specific bacilli were found in the bile in eighteen. The bacillus of mouse septicremia appeared in the conjunctiva, which became inflamed, under conditions making it probable that it did not enter from without. Among the points especially emphasized by Slierrington are tlie fol- lowing : "At a time when every drop of the circulating blood is teeming with micro-organisms there may not be the slightest transit of them into the urinary and biliary fluids then secreted, and they may be completely absent from the aqueous humor of the eye-ball." "When certain pathogenic s]iccies are employed, a number, often very consideral)lc, of tlie injected bacteria tend after a time to appear in the secretions of the kidney and liver, and their escape in the secreta is ' Sherrington, " Experiments on tlie Escape of Bacteria with the Secretions," The Joui-nal nf PalhtiUnjtj and Bacteriology, Feb., 1893. This vahiable article contains a full review of the literature. 286 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. sometimes accompanied by an escape of actual blood," although not infre- (juently there is no blood in the secreta. " The evidence is aoainst believing- tiiat when this transit of bacteria across the sccretinii; nienihrane occurs tiie membrane is still normal in condition, althougiiat the same time it need not be ruptured or pervious to red blood-corpuscles." " The fact that the escape of the bacteria tends to occur, not immedi- ately upon the introduction of them wholesale into the circulation, but in the late stages of the communicated disease, suggests that tiie healthy secreting membranes arc not pervious to bacteria, and that only after soluble jioisons j)roduced by the infection have had time to act upon them do the membranes became pervious to tlie germs. The fact that species which are innocuous did not in the experiments appear in tiie secreta at any time is in conformity with this conclusion." Pernice and iScagliosi experimented with stapiiylococcus aureus, bacillus prodigiosus, bacillus anthracis, bacillus pyticyaneus, and liacillus subtilis, and they found that these bacteria were constantly excreted through the urine and bile, and might escape through various mucous membranes. This excretion begins six to eight hours after their inti'o- duction. Virulent bacteria retain their virulence, as a rule, in the excreta. There are numerous observations in human beings of the escape of infectious bacteria tin-ough tiie excretions. The pyogenic cocci are par- ticularly prone to settle in the kidney and cause focal inflammations, but even witiiout actual foci of suppuration they often escape into tlie urine. Xannotti and Baciochi, Ijoth in grave suppurative processes and in slight ones, foimd the specific bacteria ■with great frequency and of customary virulence in the uriiK'. They disapjieared from the urine t^^■cnty-four to tiiirty-six hours after tlie evacuation of the pus. In experimental pyo- cyaneus infections the specific bacillus is found regularly in the urine. The micrococcus lanceolatus in pneumonia and other pnenmococcus infections, the tvj)hoid bacillus in typhoid fever, the streptococci in erysipelas and other streptococcus infections, are often present in the urine. The bacillus coli communis, tlie most common of all secondary invaders, often escapes through the kidney. Pathogenic bacteria are eliminated very often through the bile. One of the most common lesions in various infectious diseases is the presence of focal necroses, sometimes visible to the naked eye and sometimes seen only with the microscope, in tiie liver, and these jiermit the passage of bacteria into the bile. It is not, however, necessary that such necroses should be present in order to permit tlie escape of bacteria into the bile. Blachstein, in experiments made under the direction of the writer,^ demonstrated that the colon bacillus and the typhoid bacillus injected into the veins of rabbits often aji])eared in the bile, ^\•llere they frc(|uently remained alive and in large number wcel^s and months after they had disappeared from all of the internal organs. In many of these cases there were focal necroses in the liver. The passage from the circulation into the bile of the anthrax bacillns, of the micrococcus lanceolatus, the streptococcus pyogenes, the pyogenic stajihylococci, the bacillus pyocya- ueus, and of other bacteria has been repeatedly demonstrated. Patho- ELIMINATION OF BACTERIA IN THE SECRETIONS. 287 gcnic bacteria arc quite as frequently discharged through the bile as through the urine. Of course bacteria iu the bile will enter the intestine with this secre- tion, and it is therefore not always easy to determine whether specific pathogenic bacteria found in the intestine in infectious diseases have been discharged through the wall of the intestine or through the liver. ]\Iost of the observations recorded concerning the transit of bacteria through the intestinal wall from the circulation have not been made so as to determine whether or not the escape is really through the intestinal mucosa or by way of the bile. Nevertheless, the frequency with which hemorrhages, necroses, inflanunations, and ulcers of the hitestinal nuicous membrane occur in various infectious diseases makes it highly probable that pathogenic bacteria may be eliminated through this channel. Cer- tain it is that the specific infectious bacteria, not only of diseases like typhoid fever, cholera, and tuberculosis, characterized by definite intes- tinal lesions, but of many other diseases, such as croupous pneumonia, septieiemia, py;emia, are often found in the ffpces. Tuljercle l)acilli may be present in the milk of tnljcrculous cows even when there is no demonstrable tuberculosis of the udder. The state- ments as to the frequency of this occurrence vary. Ernst demonstrated by the microscope tubercle bacilli in the milk of 28.5 per cent, of the thirty-five tuberculous cows examined, and by in(jculation experiments in 50 per cent, of fourteen cows. Bang by the inot'ulation test found tubercle bacilli in the milk of only nine out of sixty-three tuberculous cows without mammary tuberculosis. When the udder is tuberculous the bacilli are always in the milk. Numerous observations have been made to determine whether or not the pyogenic cocci are excreted with the milk in puerperal infections, but since we now know that the stajihylococcus albus is regularly, and the staphylococcus aureus is sometimes, present in the milk of healthy women, the demonstration of these cocci in the milk in eases of puer- peral fever has lost much of its diagnostic significance. There is, however, reason to believe that, although the ordinary source of the staphylococci found in the milk is from the skin, they may be excreted through the gland from the blood in pyogenics infections. The presence of streptococci in the milk is more significant of such ex- cretion than that of staphylococi'i. In several cases of puerjieral fever streptococci have been found in the milk, although more fre- quently they are missed in this secretion under these circumstances. There is evidence that the ]iyogenic cocci causing mastitis may enter either from without through the lacteal ducts or may have been depos- ited from the circulating blood. Karlinski claims to have demonstrated that the staphylococcus aureus injected into the blood of rabbits mav be excreted through the mammary gland. Foil and Bordoni-Ulfreduzzi and Bozzolo have found pneumococci in the milk of pregnant women affected with lobar pneumonia, and the former investigators demonstrated their presence in the milk of preg- nant rabbits inoculated with this organism, and noted j)neumococcus septicicmia in young rabbits which sucked the breast of their infected mothers. The typhoid bacillus has been fi)inid exceptionally in the milk in cases 288 GENERAL BACTERTOLOGY OF SURGICAL INFECTIOyS. of typhoid fever. In ex]icriin(iital imtlirax the specific bacillus appears in the milk only exoe|)tionally. Brunner found the staphylococcus all)us, von Eiselsberroducts : that of the niici'ococcus lanceolatus by combination with the proteus vulga'ris, the anthrax bacillus, or the diphtheria bacillus (Monti, Pane, Miihlmann, Mya) ; the streptococcus pyogenes with the proteus vulgaris, bacillus prodigiosus, bacillus coli communis (Klein, Monod, and Macaigne) ; the pyogenic sta|)]iyloc()cci with the bacillus pro- digiosus or its products and otiier bacterial ))r(iducts (Grawitz and De Bary and others) ; the diphtheria bacillus with the streptococcus ])vogenes or its products (Roux and Yersin and others) ; the typhoid bacillus with the streptococcus pyogenes, colon bacillus, and proteus, or their products (Vincent, Sanarelli) ; the bacillus coli communis M'ith the typhoid bacil- 292 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. lus and the streptococcus pyogenes (Pisenti and Hianclii-Mariotti) ; the bacillus of symptomatic; authrax with the liacillus jjrotligiosus (Roller). Mention has already been made oi' the pathological importance of tiic association of the tetanus bacillus with other bacteria. Of especial interest are the experiments of Prudtieu demonstrating that the intra- tracheal injection of cultures of the streptococcus pyogenes in tuber- culous rabbits leads to the formation of regular phthisical cavities in the lungs — a result which is not obtained by the inoculation of either micro- organism alone. Jiernheini has demonstrated that the dijilitln'ria bacillus grows more luxuriantly and with a larger production (jf toxin in the filtrate of streptococcus bouillon cultures than in ordinary bouillon. A most important group of infections, many of them of surgical importance, is furnished by the secondary invasion of pathogenic bacteria in the course of various infectious diseases, such as ty])hoid fever, tuber- culosis, diphtheria, scarlet fever, small-pox, and other exantliematous fevers. The streptococcus pyogenes is more frequently the infections agent in these secondary infections than any other organism, but the other pyogenic cocci are not uncommonly concerned. The primary infection increases susceptibility to these common pyogenic cocci, which often find the way open for their invasion by some lesion of an exposed surface of the body. It is also very jirolialtle that the primary infection may brine about conditions which enhance the virulence of the bacteria concerned in the secondary infection. Although it is not necessary to suppose that these common secondary invaders are always derived from tlu)se \\hich are present in health uj)on exposed mucous membranes, nevertheless they doubtless often have this origin. Pyogenic cocci obtained from these .■secondary infections ai-e usually, although by no means always, more virulent than when cultivated irom the healthy mucous membranes. Of especial frequency and importance among the mixed and second- ary infections here in consideration is the association of the tubercle bacillus with the streptococcus jn'ogenes, the tyj)hoid bacillus Avitli pyogenic cocci, and the diphtheria bacillus with streptococci. The characters of the various mixed infections are probably deter- mined less by a direct influence of one bacterial species or its products upon another, although this factor ajipears in some cases to be an import- ant one, than by the action exerted by one or both species upon the resisting powers of the fluids and cells of the body. Immunity and Pkedisposition. — In no class of infectious diseases is the influence of ])redis])osition as an etiological factor more a])parcnt than in many of the surgical infections. If a wound could be kept entirely free from pathogenic bacteria, it would not suppurate, no matter how favorable in other respects the local and general conditions for infec- tion might be. The occurrence of suppuration in human beings from sterile chemical irritants is so exceptional that we need not consider this form of suppuration here. It is not, however, possible in all, or even in most, cases to keep bacteria wholly out of a wound. The examina- tion of so-called aseptic wounds shows with great frequency the presence of bacteria, and notably of the white skin-coccus, but also sometimes of other pyogenic cocci, including the staphylococcus aureus. Although the cocci found under these circumstances are usually of -weakened viru- CONDITIOXS FAVORING THE DEVELOPMENT OF INFECTIONS. 293 lence, nevertheless, as shown bv Biidinger and others, they are of some virulence, and may be decidedly virulent. The frequency with which pyogenic bacteria enter wounds is by no means expressed by the fre- quency with which wounds suppurate. Every surgeon knows that in certain persons and in certain conditions of the body a wound is much more likely to suppurate than in others, altliough the same precautions are taken to guard against the entrance of micro-organisms. It is there- fore a matter of prime importance, no less of practical than of scientific interest, to learn, so far as we may, what are the conditions which jire- dispose an individual to infection. Unfortunately, we are at present only imperfectly informed as to many of these conditions. Predisposition is of most inqiortance in the etiology of those infec- tious diseases which are caused by micro-organisms to which the individ- ual or the species is not in the Iiigiiest degree susceptible. Tiie pyogenic cocci, in general, belong to this group of micro-organisms, although they may exist in a condition of such exalted virulence that predisposition becomes a factor of no significance. The degree of susceptibility to a specific micro-organism influences not only the capacity to acquire the infection, but also the course, severity, and character of the infection. In an individual of great susceptibility a micro-organism of attenuated virulence may produce effects which in a relatively insusceptible person can be accomplished only by a highly virulent micro-organism of the same species. The astonishing variety of affections which may under different cir- cumstances be caused by pyogenic cocci, from a simple epidermal pustule to tile gravest septicemia and pyarnia, from a serous to a suppurative inflammation, are to be explained in part by variations in the local or general susceptibility of the individual, although, as already explained, other factors, such as the degree of virulence of the organism, the manner of invasion, and the number of organisms introduced, are also inq)ortant. We possess aliundant experimental evidence of the fact that in the relatively insusceptible many patliogenic bacteria remain localized, causing inflauiniation, whereas tiie same bacteria in the highly susceptible invatle the blood and internal organs, causing general septictemia. Ijimuxity. — Our comprehension of the nature and importance of predisposition as a factor in the causation of infectious diseases has been facilitatt'd by the increase of our knowledge concerning the factors upon M'iiicii immunity from the invasion and nuiltiplication of bacteria depends; but our understanding of the nature of innnuuity is still most incom- plete. It is not necessary for our purjjoscs in this connection to enter into a detailed consideration of the various doctrines of immunity, important as are the results of recent investigations upon tliis subject. It will suffice to state briefly tlie more inqiortant facts and hypotheses so far as they bear upon the (piestion now under consideration.' We distinguish natural or hereditary imuuuiity from acquired immu- nity. Imnuinity may be acquired by recovery from an attack of a specific infectious disease, or may be artificially produced by vaccination with the specific micro-organism or its products, or by the injection of the ' The following statements concerning immunity are taken chiefly from the fuller article on this subject by the writer in Pepper's Teil-Iiook of the Theory and Practice of Medicine by American Teachers, vol. ii., Philadelphia, 1894. 294 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. hliHKl-.scrum or otlier fluids fmin individuals rcndorcd artificially iniiiiune. It is certain that the various kiniis of immunity do not all depend upon the same causes. The leading theories of immunity may be brought into two classes — one which attributes immunity to the direct and active intervention of the living cells of the body, and the other which explains immunity by the ])roperties of the extra-cellular fluids. In the last analysis these properties of the body fluids nnist dei)eud upon the activities of cells, so that we must have recourse either directly or indirectly to cellular functions in any adequate explanation of im- munity. The leading representative of the cellular theories is the phagocytic theory, so elaborately and charmingly developed by ^Nletschnikoff. This supposes that immunity depends u})on the seizure of invading micro- organisms by anitt'boitl cells, chiefly leucocytes and other mesodermic cells, and the subsequent destruction of these organisms in the interior of the cells. According to this view the leucocytes are charged with the defence of the l)ody and engage in a veritable conflict \\ith the parasites. The significance of inflammation, according to Metsclmikotf, is to bring the leucocytes to the seat of danger, to which they arc attracted by the j^ositivcly chemotactic substances furnished by the micro-organ- isms. Immunity is acquired when the phagocytes have gained tolerance of the poisons of the specific micro-organism and are no longer repelled by them. There exists in a very large number of cases unquestionably a paral- lelism between phagocytosis and immunity, but the action of phagocytosis is by no means always apparent. \ye know that micro-organisms may be destroyed by extra-cellular agencies as well as within the cells, and it is a fair question whether the micro-organisms before their reception by cells have not already been damaged by these other agencies. It is true that jNIetschnikofF has proven that phagocytes may take ujj li\-ing and virulent bacteria, and that these bacteria may degenerate and die in the interior of cells, but he has not shown that, as a rule, bacteria when taken up by cells have suft'ered no injury from extra-cellular agencies. We possess direct observations which prove that bacteria introduced into the body may degenerate and die not only within cells, but also outside of them in the humors. The humoral theories of naturid inuuunity have been based largely upon the demonstration by Nuttall, Buchner, and others of the bacteri- cidal properties of the blood and other fluids of the body. Buchner has given the name of " alexins," and Hankin that of " defensive protcids," to these bactericidal substances. The bactericidal alexins are believed by Kossell and Vaughan to be nucleins or nucleinic acid. Their action is not exerted equally ujjon all bacteria, and there is often no parallelism between the ])resence of this bactericidal property in the blood of the normal animal and the insusceptibility of the animal to a given micro- organism. The important observation has been made, however, that as the result of the introduction of certain micro-organisms the body fluids may acquire bactericidal proj)crties as regards the organism intro- duced. The search for the origin of the alexins has led to the view that they b CONDITIONS FAVORING THE DEVELOPMENT OF INFECTIONS. 295 are derived directly from the cells, and particularly from the leucocytes. This lias led to a partial reconciliation between the phagocytic and the most prominent humoral tiieories of immunity. The leucocytes and other cells are, indeed, tlie defenders of the body against intruding micro- organisms. I'hey furnisli the alexins, the weajions of attack. AVhere they accunudate the defensive material is concentrated, but it is not necessary that the bacteria should be actually incorporated in the body of the cells, although the germicidal properties may be more intense within than without tlie cells. Such is the explanation of natural inunu- nitv now adopted l)y Buchner and many others. There is a kind of acquired inununity wliich is not known to have a parallel in forms of natural imnuuiity. Tiiis is tlie so-called antitoxic immunity. Here, as the result of vaccination with the specific micro- organism or its products, tiie blood and fluids of the immunized animal have acquired the property of neutralizing the poison formed by the specific organism from which the individual has been immunized. The principles of antitoxic immunity liave been worked out for the toxic infections, tetanus and diphtheria. The same principle doubtless holds good for acquired immunity from some other diseases, but for how large a number we cannot say. A most important characteristic of this anti- toxic immunity is that by successive injections of increasing amounts of the ])oisonous substances into the animal the antitoxic or immunizing power of the fluids can be augmented to an astounding degree. It is in this way that the antitoxic power of the fluids may be rendered sufticiently high to exert curative effects when injected after the reception of the specific micro-organism or its ju'oducts. This so-called serum-therapy has thus far Ijcen apjilied with beneficial results only to cases of tetanus and of di[)litlicria, and, as regards human beings, it is more efficient in diphtiieria tiian in tetanus. Local Piiedisposition. — The term " predisposition " is often used in a loose sense to designate all sorts of conditions M'hich increase the chances of infection, or which augment susceptibility to infection, or which influence the localization, duration, character, or severity of infec- tions. A name which is used to refer to conditions belonging to such ditterent categories, having often nothing in common, is of course objec- tional)le, but common usage sanctions the term, and there appears to be no lietter one under which to include the various points here to be con- sidered. We distinguish racial and individual predisposition, inherited and acquired predisposition, local and general ])redisposition. Instances abound of diflerences in susceptibility to infectious diseases between ditt'erent species of animals, and tiiere are differences also between different races of nien ; but tho most important kind of predisposition, as regards those surgical infections which we are here considering, is individual predisposition. This iudividnal |)redisposition may be either inherited or acquired. It may pertain only to one part or to certain parts of the body, or it may belong to the body as a whole. A\'e cannot in many instances determine whether the predisposition is local or general, and, indeed, it is often imjiossible to draw any sharp dividing-line between local and general predisposition. 296 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. Local predisposition may be limited to one or more of the portals of entry for miero-(jriianisnis, or it may exist at some point within the Ixidy, constitiitint;- a so-called locus minoris resistcntiie. We shall consider first prcdisposinii' causes of infection at the portals of entry. We shall have in view under this headinj;- min'c pai'ticidarly causes which act locally, hut it is to be understood that general ])redis- posing factors to be described later may produce local predisposition. Under the heading of " Intlannnation produced by Bacteria" Dr. Councilman in the pre(;eding article has described the intluenec upon pyogenic infections of many local predisposing factors, such as the character of the tissue invaded, local ana-mia, passive hypera^mia, the withdrawal of nerve-impulses from a part, rapidity of absorption, the introduction of chemical bacterial jiroducts, the presence of foreign bodies, jirevious attacks of inflammation ; and the reader is referred to Dr. Councilman's article for these points. It has there been made clear that any interference with the integrity of the tissues and of the local blood- and lymph-circulation is likely to render them more susce]>tible to jiyogcnic agents, and to influence nnfiivorably the character and course of a subsequent inflammation. Wounds through a thick layer of adipose tissue or cicatricial tissue or other poorly-vasenlarized parts are less able to resist the action of jwogenic bacteria than wounds of such vascular parts as the face. To the predisposing conditions enumerated may be added redema of tlie tissues. How important this is may be inferred from the frequency with which erysipelas and suppuration follow so slight an injury as puncture of an a?dematons scrotum or leg. Biidinger found that ])vo- genic cocci so weakened in \-irulence as to produce no effect Mhen inoc- ulated into the normal ear of a rabbit set up local suppuration Mhen inoculated into an ear rendered hy2)er8emic and a?dematous by tempo- rary application of a rubber band around the root of the ear. The withdrawal of nerve-impulses from a part may increase its lia- bility to infection. The factors here concerned are various, the most apparent ones being anaesthesia, disturbances in the lymphatic and blood circulation, and nutritive changes. The question as to the exist- ence of special trojihic nerves, the interference with whose function pre- disposes the part to infectious inflammations, has been considered by Dr. Councilman. In a personal conmiunication Dr. Weir Mitchell has kindly favored the writer with the following expression of his views on this point : " I think it true that the withdrawal of nerve-im])nlses from a part favors infection ; that the withdrawal of nerve-influence with partial failure of circulation in some cases of injury still further favors infection ; that there is a condition of traumatic nerve-irritation which, probably by its abnormal influence on nutrition, favors infection. A partial injury of a nerve sets up local neuritis and may bring on idcers of a jiecnliar character.' It seems to me that if we injure a nerve-supply, the changes in muscular and nerve conditions which immediately take place would favor such chemical changes in the tissues as to make them more or less susceptible to infection." Abnormalities in the secretions on exposed mucous surfaces and in ' Interesting examples of sucli uleere nre here cited by Dr. Mitcliell from the forth- coming book of his son, Dr. Jolin H. Jlitcliell, on Nen-e-injuries and their Remote Results. CONDITIONS FAVORING THE DEVELOPMENT OF INFECTIONS. 297 the glands communicating with them may be a local predisposing cause of iuf't'ction. Obstruction to the outflow of secretions, and the presence of calculi or foreign Ijodies in cavities or glandular ducts opening upon exposed surfaces are important prcdisjiosing causes of infection, as is exem[)lificd by inflammations of the vermiform appendix, renal pelvis, urinary and gall-ldadders, urethra, the l)iliary, pancreatic, and salivary ducts. In general, all traumatic and pathological lesions of exposed surfaces of the I)ody, such as wounds, hemorrhages, necroses, waxy degeneration, inflammation, ulcers, stricture, strangulation, pcrfn'ation, increase in greater or less degree the opportunities for the entrance, lodgement, and multiplication of pyogenic and other micro-organisms. A suppurating surface, however, offers considerable resistance to the growth and invasion into the body of most jiathogenic bacteria. Pus is endowetl with marked bactericidal properties, both in its corpuscular elements and its fluid constituents, and tlie o]>portunities for absorjition from a suppurating surface are nuich less favorable than from a fresh wound. Scstini found that the bacilli of anthrax and of rabljit sejjtica- mia when applied to a suppurating wound of tlie rabbit's skin produced no infection, although they readily did so when introduced into a fresh wound. The existence of sujipui-ation, however, lowers the general resistance of the body to bacteria. The various lesions which interrupt the continuity and integrity of the exposed surfaces of the body become most dangerous channels of infection when the general resistance of the body to infectious agents is lowered, as in various infectious fevers and constitutional diseases. J^xperiments and clinical observations have been made with reference to tile amount of damage to the intestinal coats which is requisite in order to permit the passage of bacteria from the intestinal canal into the peritoneal cavity. Most observers have found the fluid in the sac of a strangulated intestinal hernia free from bacteria in the great majority of cases. Garre found bacteria only once in eight cases ; Rovsing did not find them at all in five eases ; nor did Ziegler in five cases ; Tavel and Lanz obtained a positive result only twice in seventeen cases of in- testinal strangulation ; in two out of three omental strangulations they found l)actcria ; Tietze found bacteria in four out of nine cases, with the possibility that in some of the four cases they were accidentally intro- duced from without. Sanguineous hernial fluids with bloody infiltration of the intestinal coats were observed without the presence of bacteria, and even the fluid in sacs containing necrotic intestine did not always contain bacteria. The presence of fibrinous peritonitis over strangulated intestine does not necessarily involve the presence of Iwctcria in the exudate, as this form of peritonitis may be caused by the absorption of the chemical products of bacteria from the intestine (chemical peritonitis). Definite relations lietween the condition of the intestine and the presence of bac- teria in the hernial sac were not ol)scrvcit septicsemia, intro- duced in large number into fresh wounds, could not be prevented by tlie irrigation of the wound with corrosive sublimate (1 : 1000) or carbolic acid (5 per cent.) or other antiseptics. But some of the bacteria thus introduced, as has already been ex])lained, are immediately or very soon al)sorlicd from fresh wounds, and if one bacillus or a very few bacilli of the kind used by Schimmelbuseh were thus absorbed, the death of the animal was sure to follow; whereas a similar absorption of a few ordinary pyogenic cocci is usually without significance. It is evident that these experiments are not conclusive as to the influence of antiseptics upon bacteria which remain in the wound, and are not applicable to the ordi- nary conditions of wound-infection during a surgical operation. Henle' in his experiments conformed more closely to conditions of wound-infection in man. He found that in wounds of the rab1)it's ear inoculated with streptococcus ])us the streptococci remained in tin' wound for six hours, after which the cocci began to occupy the neighboring lymph-spaces. He found that regularly up to the end of the second hour a complete disinfection of the M'ound with sublimate (1 : 1000) or ' Henle, Cenlralblalt /iir Chirurgie, 1894, No. 30, Beilage. CONDITIONS FA VOBING THE DEVELOPMENT OF INFECTIONS. 301 carbolic acid (4 per cent.) could be attained, and that even after six hours the disinfection sometimes })revented tiie development of the disease, and, if not completely successful, rendered the subsc(|Ui'nt infection milder than in the inoculated control ear wliicli was not disinfected. Loffler has shown bv his carcftd tests of the action of various anti- septic substances upon diphtheritic throats that it is possible to destroy the superficial bacteria by antiseptics without serious injury to the tissues. It is possible that disinfectants, without actually killing bacteria, may restrain their power of development or weaken their virulence. Messner' experimented by inocidating fresh wounds of rabbits with pus or with cultures eontaininji' pyogenic cocci, wiiich caused [)rogressive phlegmonous inflammation with fatal termination. He found that, with one exception, all of the ten wounds inoculated with the cocci, and then irrigated with sterile salt-solution and treated aseptically, suppurated, witli the development of progressive phlegmons which killed the animal Mithin two weeks. On the other hand, all of the ten wounds, with one exception, similarly inoculated and treated antiseptically with lysol or 3 per cent, carbolic-acid solution, healed and the animals survived. Two of the wounds treated antisejjtically healed without suppuration ; the remaining eight suppurated, showing that the cocci had not actually been destroyed, but the process remained localized. Pus from the wounds treated aseptically presei'ved its virulence, whereas pus from the wounds treated antiseptically was devoid of virulence when inoculated into animals. Hermann and others have shown that if carbolic acid, corrosive sub- limate, and various other chemical irritants be injected subcutaneously into the tissues and soon afterward pyogenic micro-organisms be injected into the same locality, the formation of an abscess is much more likely to follow than when the bacteria are injected into the healthy tissues. But, as Messner has shown, a similar favoring influence upon the devel- opment of suppuration under these circumstances is exerted by the injec- tion of common salt-solution into the subcutaneous tissues. These exper- iments are not a])])licable to the conditions existing in an open wound, Imt tliev confirm clinical observations as to the great danger of intro- ducing into tlie subcutaneous tissues of man, with a hypodermic syringe, fluids containing pyogenic l)acteria. Uncpiestionably, the presence of necroses, such as may be produced by strong chemical disinfectants, -jiredisposes to pyogenic infection. In some situations, as in a closed cavity like the jieritoneal, the jiresence of even superficial necroses, which may afl'ect oidy the endothelial cells, is an important ])redisposing cause of infection, but only experience can decide whetiier such slight sujierficial necrosis or other injury wliich the ordinary antiseptics may prodnce in an external wound is in itself an important predisposing factor in the pyogenic infection of wounds, or even if a predisposing factor is not more than counterbalanced by bene- ficial influences exerted by tlie a|)plication of antiseptics. Messner has reported experiments on rabl)its which seem to show that the irrigation of fresh wounds with 3 per cent, carbolic-acid solution does not lessen the \ital resistance of the tissues in a wound to subsequent inoculation with pyogenic cocci. ' Jlessner, Jhid. 302 GENERAL BACTEBIOLOaY OF SUROTCAL INFECTIONS. Experiments upon animals, tlicrcforc, favor ratlior than o])post' the antiseptic treatment of wounds, as distinguished from so-ealled asepsis. We turn now to the consideration of local predisposition existing at some jioint within the body, the so-called locus minoris resisteutise. After the infectious agents have passed through the portal of entry and entered the general circulation tluy may find local conditions favoring their lodge- ment and development. Without such local predisposition they are often incapable of doing any harm. Injury, inflammation, and other pre-existing disease of an internal part are important and common conditions favoring the lodgement and growth of micro-organisms. The classical experiment of Chauveau many years ago demonstrated the ])redisposition of injured internal parts to infection. He twisted off without ru])ture of the skin one of the testicles of a young ram from its vascular connections (bistournage), and observed that when he had injected shortly before the operation putrid fluid con- taining micro-organisms directly into the circulation the injured testicle became the seat of septic gangrene, while without such injection the tes- ticle became neci'otic and was absorbed without becoming infected. The experiments of Rosenbaeh, Orth and ^\ yssokowitch, Prudden, and others have shown that bacteria do not readily become attached to the smooth surface of the heart-valves, but that pyogenic cocci readily adhere and set up septic endocarditis when the valves have been jjre- viously torn by a sterile probe passed down the carotid artery. The predisposition of injured joints and Ijones to the settlement of pyogenic cocci and of tubercle bacilli is established both by clinical and exper- imental observations. Pyogenic cocci often invade foci of disease caused primarily by other organisms, as is exemplified in tuberculous and gonor- rhoeal arthritis, actinomycosis, echinococcus cysts, amoebic abscesses of the liver, etc. In some situations, particularly in the kidney and urinary tract, the colon bacillus often settles in pre-existing foci of disease. The ansemic and dry conditicin of the lung induced l)y pulmonary stenosis favors the development of pulmonary tuberculosis. The hypersemic and moist condition associated with mitral regurgitation is comjiaratively unfavorable to such development, although by no means excluding this disease. Pyogenic cocci not infrequently settle in the joint-lesions of locomotor ataxia and cause suppuration. The existence of a diseased or injured part within the body by no means involves, of necessity, the localization therein of infectious jjro- cesses which may be caused by pathogenic micro-organisms in the circu- lation. The damaged part may be spared and an apparently healthy part attacked. The endeavor to obtain experimentally in animals the localization of suppuration in a fractured bone or other injured or dis- eased part by pyogenic cocci injected into the circulation often fails, and in the hands of Rinne failed so regularly that he opposes, although without sufficient reason, the whole doctrine of locus minoris resistentise. By a different line of expei'imentation Gottstein came to the same con- clusion as Rinne. We are undoubtedly able in some cases to explain the localization of an infection by such apparent local predisposing causes as those which have been mentioned, but in many, indeed in the majority of, instances of localized infections of internal parts M'e are unable to give any satis- CONDITIONS FA VOEINO THE DEVELOPMENT OF INFECTIONS. 303 factory explanation of the localization. We know that many patho- genic micro-organisms have a decided preference for certain organs and tissues. Tlie injection of the staphylococcus aureus into the circulation of rabbits does not lead to the formation of abscesses in all parts of the body, althougli tlie cocci must be carried by the blood-current evcry- Avhere. The abscesses are found most freijuently in the kidneys and myocardium, sometimes in the muscles elsewhei-e, and in young ral)bits often in the bone-marrow and joints. To say that the tissues in one part of the body offer better conditions for the growth of the micro- organisms than in other parts is only another way of saying that the organisms jynxhice disease in one part and not in another. Such phrases offer no real explanation unless the nature of these Ijetter conditions can be defined. Sometimes we can explain the localization by the manner of recep- tion of the virus, the vascular relation of the part to infected areas, the size and number of the capillaries, the velocity of the circulation, and the readiness witli whicli foreign particles arc filtered out. We know that fine particles are deposited from the lymphatic current in the lymph- glands, and from the blood-circulation chiefly in the spleen, mari'ow of the bones, liver, and lymph-glands. More often we are unable to give any adequate exiilanation of the localization of an infectious process in internal parts of the body. General Predisposition. — Under this heading we shall consider predisposing causes wiiich act more or less generally upon the whole body. The effect of such causes may be to increase the susceptibility of the whole body or only of pai'ticular pai'ts of the body to infection. The factors here concerned are for the most part less tangible than the local causes of ])redisposition. Organs and parts of tlic body may inherit special vulnerability to certain infections. Susce[)til)ility to certain infectious diseases may be manifest in races and families. The negro race is less susceptible to yellow fever than the white. Algerian sheep are in large measure insus- ceptible to anthrax, which is very fatal to other sheep. Black rats are more resistant than gray, and gray rats more resistant than white, to anthrax (IMiillcr). Age intlueiK'es predisposition, as regards some infectious diseases favor- ably, as regards others unfavorably. Wounds in children, as a rule, heal more (juickly, and with less danger of suppuration should pyogenic bacteria enter, than in old jjcople. Certain infectious diseases are most common in infancy, otliers in adolescence or in maturity or in old age. Osteomyelitis is nuich more common in eiiildren than in adults. This has been attributed to the predisposing influence of injuries to which children are more liable. Doubtless injuries enter into the causation as a predisposing factor, but it has been shown experimentally that there is a special susceptibility of the bone-marrow of young growing animals to infection by jn'ogenic cocci injected into the circulation (Rodet, Colzi, Courmont and .Taboulay, Tvannclongue and Achard, Lexer). In labora- tory experiments young animals, as a rule, are found to be more suscept- ible to most pathogenic bacteria than old ones. There is a special insus- ceptibility of sucklings during the first months of life to certain infectious diseases, such as mumps, measles, scarlet fever. As will be explained 304 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. later, the embryo possesses remarkable insusceptibility to some infec- tions. There is no evidence that tiiore is any difFerence in predisposition to infection between males and females, except as regards infections directly related to sexual functions. General antemia, induced by loss of blood, has been shown experi- mentally to increase susceptibility to infection with various micro-organ- isms, including the pyogenic cocci, Friedliinder's bacillus, and the an- thrax bacillus (Rodet, Gartner, Ghauveau, and others). Operative and other wounds arc more likely to su]ij)urate when there has been much hemorrhage than when the loss of lilood is slight. In general, imjiaired vitality and nutrition of the body may predispose to certain infections, including wound-infection. More or less plausible predisposing causes operating in this May are bad and insufficient food, overwork, depressing emotions, exposure to heat or cold, overcrowding, bad air, and, in general, insanitary surroundings and all conditions of misery. A large number of experiments ha\e been made upon animals to determine the influence of various factors in increasing susceptibility to infection. The results of these experiments are interesting and suggest- ive in many ways. Some of them evidently correspond to conditions observed in man, but it is to lie remembered that without additional evi- dence we have no right to a])ply the results directly to human beings, or to any other bacteria or other animals than those ex]ierimented with. The more important results of these animal exjoeriments are the fol- lowing : Prolonged narcosis may imjjair resistance to some pathogenic micro- organisms. Klein and Goxwell made frogs and rats highly susceptible to anthrax by narcosis witli ether and chlorof )rm, and similar results have been obtained with curare, alcohol, chloral, morphine, and upon other animals and with other diseases. In speaking of the effect of antesthetics in predisposing to wound-infection Eoswell Park ' says : " There is good reason to think that chloroform and etlier administered for some time may produce such changes in the blood and tissues that vital processes of repair, cell-resistance, and chemotaxis may be so far interfered Mith as to facilitate subsequent infection." Feser, Hankin, and Miiller found that rats fed on bread are more susceptible to anthrax than those fed on meat. Miiller observed the same degree of insusceptibility when the extractive substances from meat were fed. Canalis and Morpurgo, and Sacchi rendered pigeons highly suscept- ible to anthrax by hunger, and Bouchard noted the lowering or disap- pearance of artificial immunity in rabbits from anthrax by starvation. Prolonged abstinence from water was observed by Pernice and Alessi to render relatively insusceptible animals more susceptible to anthrax. Charrin and Roger found in fatiy-ue induced bv working a treadwheel . . ... * a factor which increased the .suscc])tibility of rats to anthrax and symp- tomatic anthrax. Various chemical substances introduced into the body may increase susceptibility to certain infections. Gottstein and Mya and Sanarelli have shown that poisons, such as chlorates, pyrogallic acid, pyridin, ' Park, loc. cit. CONDITIONS FAVORING THE DEVELOPMENT OF INFECTIONS. 305 ■whifli destroy red blood-corpuscles, may render insusceptible animals highly susceptible to certain pathogenic micro-organisms, although hse- matolysis thus produced in the case of some animals and certain micro- organisms did not weaken natural immunity. Bonome found tliat luematolysis and hajmoglobinuria causeil by injection of water into the circulation of rabbits lessened the bactericidal power of the blood as regiirds the staphylococcus aureus. By feeding w'hite mice with phlor- idzin, which j)roduces glycosuria, Leo i-endered these animals highly susceptible to glanders, from whicli normally tliey are immune. Tlie most important class of experiments showing the predisposing influence of certain chemical substances upon infection are those in wliich various ferments and bacterial products have been used. In considering bacterial association (page 291) attention has already been called to the fact that the chemical products of some bacteria favor the development of infection with other bacteria. The susceptibility of an animal to infection witli a specific micro-organism can often be increased by the preliminary or simultaneous injection of the products of the organism. It is not only the products of jjathogenic bacteria which may thus increase susceptibility, but also those of certain saprophytic varieties, particularly of the ordinary putrefactive bacillus proteus. Nor is it necessary that tlie bacterial products in order to weaken resistance to infection sliould cause distinct toxic symptoms. We do not possess any satisfactory experimental evidence that the volatile and stinking products of putrefactive decomposition augment susceptibility to infection. Park, Bouchard, and others lay much emphasis upon auto-intoxication from absorption of fermentative products in the stomach and intestine as a [ircdisposiug cause of infection, ])articularly with the pyogenic cocci. Neumann and Canon, in order to test the predisposing influence of absorption of fermentative products from tlie intestine, ligated aseptically the small intestine of rabbits near the ileo-csecal valve and injected sub- cutaneously a streptococcus culture. The animals with intestinal obstruc- tion, with few exceptions, died with streptococcus septic£emia, whereas the streptococci injected into normal rabbits produced only local inflam- mation at the point of injection. The ligation of the intestine close to the stouiach was not followed by generalization of the stre]>tococcus infection. So deadly an operation as ligation of the intestine introduces so many other factors than the possible absorption of poisonous intestinal products that these experiments caimot be considered to prove what they were intended to demonstrate. Extirpation of the kidneys, with sub- cutaneous injection of streptococci, also leads to general streptococcus infection. That many acute and chronic diseases lower the resistance of the body to pathogenic micro-organisms has repeatedly been mentioned in the course of this article, and is universally admitted. The influence of certain infectious diseases in favoring the development of secondary and mixed infections has been sufficiently i-efcrred to. Diabetes mellitus is well known to increase in a marked degree the susceptibility to infection, particularly with pyogenic cocci and the tubercle bacillus. Among other diseases characterized by lessened resist- ance to infection may be especially mentioned acute and chronic Bright's disease, arterio-sclerosis, cardiac disease, alcoholism, syphilis, rickets, Vol. 1—20 306 GENERAL BACTERIOLOGY OF SURGICAL IXFECTIONS. sciu'vv, leucocythsemia, Hodgkin's disease. All (if these diseases are prone to lessen resistance to pyogenic cocci, and especially to the strep- tococcus pyogenes. A localized streptococcus infection is much more likely to become generalized when it develops in persons affected \\ith any of these diseases than when it appears in a previously healthy person. Here also attention may be called to the terminal strepto- coccus septicaemias occurring in Bright's disease, heart disease, and various chronic diseases. They may not be distinguished by character- istic symptoms during life, and are to be ranked among such events as terminal pneumonia and dysentery. The portal of entry is most fre- quently the lungs, skin, and intestine. Of 218 autopsies of chronic Bright's disease, general arterio-sclerosis, and chronic heart disease at the Johns Hopkins Hospital, in 154 there were definite infectious. Of .32 cases of local streptococcus infection, excluding perforative peritonitis, tabulated from the autopsy records of the hospital by the writer, chronic nephritis, general arterio-sclerosis, or chronic heart disease was present in 18. In 11 out of 14 cases of general streptococcus infection one or more of these diseases was present. We have observed several cases of general streptococcus infection in Icuco- cytha?mia and Hodgkin's disease. In a large number of cases we are able to find no explanation of the existence of individual predisposition. In conceding to predisposition its full importance as a factor in the etiology of surgical infections, we are not to forget that pyogenic cocci occur of such virulence that they can readily overcome the natural resist- ance of the most insusceptible human being. FcETAL Infection. The embr}-o may be infected by transmission of the specific micro- organism with the ovum or semen. The only example of this germinal infection in which the conditions are thoroughly understood is jiebrine of silkworms caused by sporozoa, which have been studied in all stages of transit through the ovum and si)ermatozoa to the infected offspring. The only infectious disease of human beings which has been proven to be capable of conveyance to the offspring through the ovum or spermatozoa is syphilis. Congenital syphilis is usually due to germinal infection, and it'may come from either a syphilitic father or a syphilitic mother. Intra-uterine or placental infection of the foetus may occur in many infectious diseases. Although the intact placenta is a perfect jihysiologi- cal filter, which does not permit the passage of inanimate particles from the blood of the mother to that of the foetus, nevertheless pathogenic micro-organisms are capable of breaking through this barrier. The conditions Avhich permit the passage of micro-organisms from mother to foetus can sometimes be demonstrated in the form of definite lesions of the placenta, either pre-existing or caused by the specific micro-organ- isms or their products. Circulatory disturbances, hemorrhages, defects in the epithelium covering the chorion villi, areas of necrosis, and tuber- cles in the placenta have been observed with more or less frequency in cases of fa?tal infection, but often no placental lesion could be detected. F(ETAL INFECTION. 307 In the later stages of pregnancy and during parturition the anatomical and physiological conditions would seem to be more favorable for the escape of micro-organisms from the mother's blood to the foetus than in the early stages. Some micro-organisms are much better adapted than others to pass through the placenta from mother to fcetus. In animals the bacilli of chicken cholera and of symptomatic anthrax and the pyogenic cocci frequently make this passage. Although there has been much contro- versy as to anthrax, it is now settled that anthrax bacilli often pass from mother to fa^tus, but generally in such small numbers and without sub- secpient multijilication in the fcetus as to require special methods and careful search for their detection. In human beings infection of the fwtus in utero has been observed in small-pox, measles, scarlet fever, relapsing fever, syphilis, tuberculosis, croupous pneumonia, typhoid fever, anthrax, and affections caused by pyogenic cocci. In general, such infection is exceptional, but in some diseases it is comparatively common. Surgical importance attaches to the fact that both experiments on animals and clinical observations show that the pyogenic cocci are frequently transmitted to the fcetus from an infected mother. Developed tuberculosis in the new-born infant is extremely rare, although it has been observed, but this rarity does not prove that tubercle bacilli may not often be transmitted from mother to foetus. It takes time and susceptibility for tubercle bacilli to produce recognizable lesions. Tubercle bacilli without developed tuberculosis have been repeatedly found in the fcetus of tuberculous mothers. Birch-Hirschfcld detected in a seven-months' fcetus, removed by Cfesarean section from a mother with acute miliary tuberculosis, tubercle bacilli both by micro- scopical examination and by inoculation of guinea-pigs. There were no tuberculous lesions in the fcetus. The failure to find tubercle bacilli in a large number of similar cases can hardly be regarded as proof of their absence, when one considers the difficulty of demonstrating tubercle bacilli in small number irregularly distributed through a large mass without any lesion to indicate where they are most likely to be found. Gartner finds that the transmission of tubercle bacilli from mother to fcetus is common in the experimental tuberculosis of mice, rabbits, and canary birds. There is reason to believe that the embryo offers great resistance to the growth of tubercle bacilli. Maffucci has found that tubercle bacilli inoculated into hens' eggs before incubation remained quiescent during the period of embryonic development, but caused the death of most of the chicks from tuberculosis in three weeks to four and a half months after birth. We have evidence tnat in human beings living and virulent tubercle bacilli may remain latent in the body a long time. As already mentioned, the chances of penetration of bacilli into the fcetus appear to be more favorable during the later period of pregnancy than earlier. The frequency of tuberculosis increases very rapidly with each succeeding ■week after birth, until during the second half of the first year and during the second year of life fotal tul)erculosis is very common, and then becomes less frc-quent until after jniberty. Infantile tuberculosis is far more commonly situated in internal organs, such as the lymphatic glands, 308 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. meninges, bones, and joints, without tiil)ercnions lesion on ;niv exposed surface of the body, tlian is tulxrcuiusis (if adults. Tiiese are the arguments wiiich are urged Ijy IJauingarten and others with great force in favor of frequent bacillar heritage. The majority of autiiorities, however, are rehictant to abandon the older views, and the final settlement of this important question involves great difficulties not likely to be soon overcome. The portal of entry to the fcetus is the umbilical vein, and therefore micro-ortjanisras wtiuld be carried first to the liver and the ritjht side of the heart. Corresponding to this, we find that lesions of the liver and of the right side of the heart are particularly common in congenital infections. Pyogenic cocci, as already mentioned, break through the placental barrier with comparative ease, and these are the bacteria most often associated with endocarditis, which is more common on the right side of the heart in the foetus and new-born than in the adult. Although the foetus may react to pathogenic micro-organisms in the same way as the mother, or even more severely, it possesses a remarkable insusceptibility to some infections, as has been proven experimentally and clinically. There are several instances in which the specific bacteria of cn)upous pneumonia and of typhoid fever have been found in the stillborn embryos of mothers affected with these diseases, but there is no satisfactory recorded instance of an infant born with the lesions of typhoid fever or those of lobar pneumonia caused by the pneumococcus. Some bacteria which cause localized infections in the mother may pro- duce in the toetus general septicemia without localizations. General Considerations concerning Pyogenic Bacteria. The pyogenic bacteria play such a predominant role in surgical in- fections, and their pathogenic (;haracters jjresent so many jieculiarities, that it is appropriate to consider here the general relations of pyogenic bacteria to surgical infections, although the consideration of the special diseases caused by these bacteria does not fall within the scope of this article. There are no specific bacteria of suppuration. On the one hand the number of bacteria which under special conditions are capable of causing suppurative inflannnation is large, and is not limited to any particular group, and on the other hand the bacteria which are most fre(|Uently the cause of suppuration are capable of causing other forms of infiammation and of producing infection without inflammation. Certain staphylococci and streptococci, however, are found in jnirulent inflammations in human beings so much more frequently than other micro-organisms that they are the ])yogenic bacteria par e.i-ccllence, and are the ones generally understood when the expression " micro-organisms of pus" or " pvogenic bacteria" is used without any qualification. These staphylococci and streptococci are endowed with pus-producing properties in larger measure than are other bacteria, and of all their pathogenic effects the production of suppurative inflammation is the most promi- nent. The most connnon pyogenic cocci are the staphylococcus pyogenes aureus, the streptococcus pyogenes, and the staphylococcus pyogenes CONSWERATIOXS CONCERNING PYOGENIC BACTERIA. 309 albus, including the staphylococcus epiderniidis albus. In the second rank, as regards both fretiuencv and virulence, arc tlic stapliylococcus pyogenes citreus, the staphylococcus cereus allnis, and the staphylococcus cereus flavus. More common and far more important than the cocci of the latter group are the micrococcus lanceolatus and the micrococcus gonorrhoese. Although these are not always ranked among the pyogenic cocci in the restricted sense, they are genuine pus-producers. The micrococcus tetragenus septicus is rarely the sole cause of suppuration. The status of the micrococcus pyogenes tenuis is uncertain. It is per- haps identical with the micrococcus lanceolatus. There is a long list of bacilli wdiich have been shown with greater or less certainty to be capable of producing suppurative inflammations in man. The principal ones arc bacillus pyogenes fietidus, bacillus coli communis, bacillus typhi abduniinalis, bacillus tuberculosis, bacillus pyocyaneus, bacillus pneumoni;e of Friedlander, bacillus proteus. Acti- nomyces belongs to the class of schizomycetes and is a pus-producer. Several anaerobic bacilli have been found both in pure culture and associated Avith other bacteria in closed abscesses. Of these may be especially mentioned bacillus ])hlcgmones emphysematosa; of E. Fraeidvcl, which is j)robably identical witli bacillus aerogenes capsulatus previously described by Welch and Xuttall, and which occurs in some phlegmons containing gas. The list of demonstrated pus-producing bacteria is by no means ex- hausted by those enumerated. In the experience of the writer bacilli are more common causes of spontaneous abscesses in laboratory animals than cocci. A very large number of bacteria are capable of jiroducing experimental abscesses in animals. It is fair to say that not all of the bacteria mentioned above are recognized as pyogenic for man by all authorities, and particularly that some do not so regard the typhoid bacillus and the tubercle bacillus ; but in the opinion of the writer their pyogenic capacity has been demon- strated. We have very little definite information as to the underlying condi- tions which control the pyogenic manifestations of such bacteria as the typhoid bacillus, the tubercle bacillus, and others which do not ordi- narily cause purulent inflammations. These conditions seem to pertain ]>artly to the degree of virulence of the micro-organism and jiartly to the local susceptibility of the tissues invaded and the general susceptibility of the iutlividual. We find in experiments upon animals that Ijactcria of weakened virulence in susceptible animals, or those of 'usual virulence in insusceptible animals, are prone to ])roduce localized abscesses. In an animal which has been rendered artificially immune from septicsemia caused by certain pathogenic bai teria immunity is not usually produced from the develojimcnt of local abscesses by tiie specific organism, in case this is capable of forming abscesses. Statistical statements as to the relative frcfiuency with which the dif- ferent pyogenic cocci occur in general in su])purative and septic aifections vary a(u;ording to the class of cases which preponderate. The staphylo- coccus aureus is by far the most conmion micro-organism in furuncles and osteomyelitis, and is common in circumscribed subcutaneous abscesses. The streptococcus pyogenes is by far the most ci>mraon organism in 310 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. spreading plegmonous cellulitis, inflammations of serous membranes, puerperal infeetions, and sojiticremia. It is the cause of erysijiclas in practically all cases of this disease. It is a frequent cause of all kinds of inflammations of the throat and of broncho-pneumonia. The staphylo- coccus albus is often associated with the other p^-ogenic cocci, espe- cially in inflammations involving the skin. It occurs most frequently in the same general class of cases as the staphylococcus aureus. Al- tliough capable of causing grave infections, the characters of the inflam- mations in which the white staphylococcus is found alone are usually mild. Two or more species of pyogenic cocci are often combined. The relative frequency of occurrence of the pyogenic cocci seems to vary somewhat according to the locality. Levy finds in Strassburg the staphylococcus aibus more frequently than the staphylococcus aureus in all suppurative aifections except furuncles, and he was unable to confirm the usual statement that the albus is less virulent than the aureus. The following table gives the results of the bacteriological examina- tion of 135 ambulatory and ojierative surgical cases by Dowd ' in the Vanderbilt Clinic and Cancer Hospital in New York. It affords a good idea of the relative frequency of the different pyogenic cocci in the chiss of cases which most frequently come to the attention of the surgeon : Streptococcus pyogenes alone Streptococcus pyogenes predominant Streptococcus pyogenes relatively few Staphylococcus pyogenes aureus alone Staphylococcus pyogenes aureus predominant .... Staphylococcus pyogenes aureus relatively lew .... Staphylococcus pyogenes or epidermidis albus alone . Staphylococcus pyogenes or epidermidis albus pre- dominant Staphylococcus pyogenes or epidermidis albus rela- tively few Staphylococcus cereus albus Staphylococcus citreus Bacillus pyocyaneus Bacillus coli communis Very few growths on agar No growths on agar Few undetermined colonies 9 23 3 11 S 13 1 10 3 1 12 Ha 6 1 1 3 3 3 11 6 The cases from which no growth occurred were tuberculous abscesses and buboes. 8 of the 51 cases of cellulitis showed a persistent tendency to spreading inflammation with undermining of the ti-ssues. In all of these 8 cases streptococci were foinid. In 2 cases of pysemia staphy- lococcus aureus and streptococci were present in the original woiuid, but onl}' streptococci in the metastases. It is interesting to contrast with these results of the examination ' Charles X. Dowd, "Some Considerations on Different Types of Exudative Inflam- mation," Medical Recurd, Xew York, Sept. S, 1894.

In about 500 autopsies at the Johns Hopkins Hospitiil there were found in 185 cases the follow- ing bacteria : Number of cases.

The cases with micrococcus lanceolatus are tliose in Avhich this organism was found without pneumonia or as the cause of some e.xtra-thoracic complicatioia of pneumonia. No cases are included in which the bacteria were found simply on e.xpo.sed surfaces of the body. Among the undetermined bac- teria are several interesting pathogenic forms which could not be posi- tively identified with species already described. Mention has already been made of the frequent invasion of the colon bacillus without any pathogen ic manifestations. The preceding table is inserted not with the intention of analyzing in this article the cases ' composing it, but to show the great differences l)ctween the results of the bacteriological study of living surgical cases and those of the antop.sy material of a general hospital, and especially to emphasize the preponderance of streptococcus cases over staphylo- coccus and all other pyogenic cases in such material. All of the affections caused by one species of the pyogenic cocci may l)e caused bv anv of the others. For example, the staphylococcus aureus may produce spreading phlegmons, infiaTumations of serous membranes, puerperal infections, general scptica^niia as well as the streptococcus pyo- genes, and the streptococcus pyogenes may cause circumscribed abscesses and osteomyelitis as well as the yellow or white staphylococcus. Jordan claims that the staphyh^coccus aureus may cause erysi jielas, but Petruschky does not regard his observations on this point as conclusive. J^^U'thermore, these pyogenic staphylococt'i and streptococci may cause all kinds of iuHammation besides tiie suppurative. Tiiey may, and often do, cause serous, sero-fibrinous, and fibrinous inflammations of serous membranes. The streptococcus pyogenes may cause catarrhal and fibrinous inflammations of mucous membranes. Pyogenic cocci may be the cause of simple inflanniiatory (edema or serous infiltration of the tissues. They are sometimes found in cutaneous vesicles and blebs containing clear serum. They may be the sole organisms present when ' The analysis of these cases was the sul'ject of the Middleton Goldsmith lecture by the writer in .Vpril, 1S94 {Tmiui. N. Y. I'athulwjical Society for 1894). 312 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. the inflammatory exudate is heinorrhajjic. Tlicy may produce exten- sive nocrosis of tlic tissues witli scarcely any infiammatory exudate. We find tlie same sta])hyl()C(K'ci and streptococci in tliose rarer forms of osteomyelitis which do not suppurate as in the ordinary sup]>nrative form. They are the usual cause of periostitis and ostitis alhuminosa, in A\hich the exudate is serous. A serous or sero-fibrinous inflannua- tion caused by pyogenic cocci may be transformed into a purulent one without the appearance of any new species of micro-organism. We cannot at present give any satisfact(jry explanation of these diverse effects produced by one and the same bacterial sjiecies. We seek to exjtlain these differences usually by referring to such factors as the degree of virulence of the organism, the manner of its invasion, the site of infection, and the condition of the patient. Variations in viru- lence and the general condition of the jiatieut cannot be the sole explan- ation, for these pyogenic cocci may in tiie same individual cause a sup- ])urative inflanunation in one part of the bodv and a serous or a sero-fibrinous inflammation in another part, without any bacteriological difference. We have observed this in some instances of multiple sero- sitis, and Schrank has reported a case in which periostitis ali)urainosa was associated with suppurative osteomyelitis in the same tibia. The same micro-organisms, staphylococci and streptococci, were jiresent in the exudate in both situations. They had produced pus in the bone- marrow and a simple serous exudate between the periosteum and bone. The deciding factor must have been in the tissues, and not in the micro- organisms or the general predisposition of the individual, and this same factor, the specific character of the tissues, little as we may comprehend its nature, is doubtless the explanation of their varying reactions to the same infectious agents in many other cases — a point which has been justly emphasized by Kurt Jliillcr. It might be inferred from what has been said as to the interchange- able effects produced by the different pyogenic cocci that no diagnostic or prognostic imjwrtance is to be attached to the determination of the particular species of pyogenic coccus present. If the streptococcus can do everything which the sta]>hylococci can do, if each s])ecies can pro- duce mild as well as grave infections, it is argued by some that it is of no practical importance to determine what particular micro-organism is present in a given case. It is more important for the surgeon to understand the general rela- tions of bacteria to traumatic and other jn'ogenie infections than to become familiar with the special characters of the individual micro-organisms which cause these infections, and therefore the principal part of this arti- cle has been devoted to a consideration of these general relations. But apart from the interest which pertains to the study of all asjiects of disease, even those without evident practical bearings, it would be a mistake to suppose that the bacteriological examination of infectious processes caused by pyogenic cocci is devoid of value for diagnosis, prog- nosis, or treatment. There are certain general rules as to the characters of the infections most likely to be produced by the different species of pyogenic cocci, and as to the probability of finding a given species in a certain kind of infec- tion. It would lead too far to attempt to consider here all the differ- COySIDEEATIOA^S CONCEBNmO PYOGENIC BACTERIA. 313 ent surgical infections with reference to these points. A few illustrative examples may be cited. The white staphylococcus causes severe local and general infections so infreiiueutly, at least in this country so far as we are informed, that the recognition of its exclusive presence in an inflamed external part of the body justifies the probable conclusion that the inflammation will pursue a mild course and bo readily amenable to treatment. The streptococcus pyogenes may possess all degrees of virulence. Although a streptococcus coming from a case of erysipelas or puerperal fever may not be distinguisiicd botanically from a streptococcus coming from a liealthy mucous membrane or caught from the air, it is a very different thing in its possibilities for infection. The streptococcus py- ogenes, for niore frequently than other bacteria, causes s.jjreading phleg- monous inflammations and grave forms of septicemia. The importance and the frc(picncy of streptococcus septicaemias accompanying tuberculosis, diphtheria, typhoid fever, scarlet fever, the jiuerperal state, erysipelas, cellulitis, and traumatic infections are probably not even yet sufficiently appreciated by physicians and surgeons, notwithstanding the rapid exten- sion of our knowledge of this subject in recent years. Septicemias pro- duced bv other pyogenic cocci under these circumstances, although they may be of equal "severity and similar character, are in a small minority. In view of the fearful pathogenic possil)ilities with which streptococci may be endowed, a surgeon cannot regard the presence of these micro- organisms in a wound or inflamed part with as little concern as he may the white or even the yellow staphylococcus, although it may be that the particular streptococcus in question is of relatively slight virulence. If his patient have chronic Bright's disease or general arterio-sclerosis or chronic cardiac insufficiency, tiie anxiety of the surgeon will be increased. Intlanunations of external parts produced by staphylococci are in general more amenable to treatment and rccpiire less vigorous interference than those caused by streptococci. Streptococcus cases are in general more dangerous to other surgical patients in their proximity than staphylo- coccus cases, and are therefore more likely to require isolation. The gravest staphylococcus infection with which the surgeon has commonly to deal is acute osteomyelitis. In this particular field the staphylococcus aureus takes rank over the streptococcus, although there is no specific micro-organism of osteomyelitis any more than there is of suppuration in general. Osteomyelitis may be caused by the strejito- ooccus pyogenes and other jnogenic bacteria, but, although these other bacteria not infrotpiently cause periostitis, they are very rarely the cause of tnicomplicated suppurative osteomyelitis. The especial conditions under which, in cases of infection caused by pyogenic cocci, the cocci apjiear in the blood in sufficient number to be demonstrable by our methods of examination are far from clear. We find tiiem far more frequently in the blood at autopsies, even very fresh ones, than we are able to do during life. Tiie ])yogenic cocci, like most l)athogenic bacteria, only excejitiniially are able to multi]dy in the cir- culating blood of human beings. The greater frc(picncy of their presence in demonstrable number at autopsy may be due in part to their multi- jjlication after death, but this cannot be the sole explanation, as the cocci are found in autopsies made very early after death more frequently than 814 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. they are found diirinii' lifV. T\w cxphiiiation is probably that during the last liours of life they often tind suitable conditions for their multiplica- tion in the blood. A similar phenomenon can often be observed in inoculated animals. All bacteria, includiufi; those of the typical septi- ctemias of animals, such as the bacillus of rabbit sejitica'mia, of anthrax, the micrococcus lanceolatus, injected into the blood (piickly disupjicar from the circulation. The pathogenic forms grow outsiile of the circula- ting blood, and often do not make their rca])pearancc in any considerable number in the circulation until shortly before death and after the mani- festation of grave constitutional syni|)toms. This is true of pneumo- coccus septiciemia, anthrax, and other typical septicicniias of animals. In examining the blood of living patients for pyogenic cocci a few drops of blood do not generally suffice, as the cocci are rarely so numer- ous as to be detected thus. The blood is obtained by wet cups by Petruschky, who has developed a special technique for these examina- tions. To the demonstrations of the white staphylococcus in blood with- drawn by cutting or pricking the skin, which have been made by a number of investigators, the writer attaches no diagnostic significance, for reasons which have been stated.

Staphylococci forming pigments intermediate in tint between the aureus and citreus occur, also cocci witli the production of only a very faint yellowish color, perhaps produced only after prolonged growth. This has led Lubinski and others to the view that these various pyo- genic staphylococci are only physiological varieties of one and the same species. 316 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. iSfaplii/lococcns Cereus Alhiix. — Cultivated from two abscesses by Passet (18o\voi- not considered to be demonstrated by Passet and Fliigge.

Kesenibles the aureus and albiis, but it does not liquefy gelatin and it forms no ])ignient. The staphylococcus cereus favus was isolated by Passet in ])ure culture from a chronic suppurative periostitis, but it does not appear to have been found again in abscesses. Passet was unaljle to cau.se abscess by inocadating it into animals. Diflfers from the staphylococcus cereus albus only by tlie formation of lemon-yellow pigment. Htreplococcas Pyogenes ; tStreptococras Erysipddtos (Plate I., Fig. 3). — Observed by Ogston in pus (1881); cultivated by Fehleisen from erysipelas (1883), by Rosenbach from pus (1884). The streptococcus of erysipelas does not ditfer in nu)rphology or cultural characters from the streptococcus jn'ogenes. The same pathogenic effects may be pro- duced by each in animals and in man, so that the weight of evidence is in favor of the identity of the streptococcus ervsipelatos with the streptococcus pyogenes, although opinions are still di\'ided on this question. The streptococcus pyogenes grows in chains of variable length. The individual cocci vary in size, .sometimes in the .same chain. They aver- age somewliat larger than the staphylococci. In pus they occur in chains, also in pairs. Stain readily with aniline dyes and by Gram's method. Grow Avith or without free oxygen in all ordinary culture media. Most stre])tococci grow at room temperature, but more slowly than at body tem- perature. The streptococcus pyogenes does not liquefy gelatin, or does so .slightly in some cases. Forms small, gray, granular colonies on gelatin and agar. Grows invisibly on potato, but may grow visibly. May or may not coagulate milk and cloud bouillon. Some cultures are short-lived, others may live several months. The streptococcus jiyogenes may survive in dried pus for fourteen to thirty-six days. Is killed in ten miiuites by €X])osure to 54° C. (Sternberg). Is killed in eight seconds by 3 per cent, carbolic-acid solution. Inoculated cutaneouslv into the rabliit's ear, viru- lent streptococci usually produce erysipelas, from which the animal recov- ers. The virulence is extremely varialde, and is best tested Ijy inoculating mice into the peritoneum, either with the first generation of a pure culture or directly with the blood or exudates containing the streptococci. Very virulent streptococci in small doses produce rapidly fatal septicjemia in mice ; less virulent ones, a more or less ])roti'acted sciUicicmia or local inflammations ; and the mou.se may die after a longer or shorter period from the eilcets of the inoculation without the presence of stre])tococci at the autopsy. Streptococci are often devoid of virulence for mice. The virulence for mice does not correspond definitely to the character and severity of the streptococcus infection in the patient from whom the streptococci were obtained, although it is a general rule, with many exceptions, that the most virulent streptococci come from grave strepto- coccus infections in man. The pathogenic properties of streptococci for man have already been mentioned so far as they relate to surgical infec- tions. (See pp. 258, 25fl, 292, and the preceding section, " General Con- siderations concerning Pj-ogenic Bacteria.") BACTERIA OF SURGICAL IXFECTIOXS. 317 Streptocdcei dhtaiiied from ditferent sources, and even those culti- vated from ditferent cases of tiie siuiie disease, vary greatly in morphology, cultural characters, and pathogenic properties. So far as virulence is concerned, this property alone cannot serve as a basis of distinction into species, as this is the most variable of all properties of pathogenic micro- organisms, and in the case of no micro-organism more vurial)le than with the streptococcus jiyogenes. The virulence of streptococci a])j)ears to vary not only in degree, but in kind, so that a streptococcus endowed with the projjerty of producing one kind of infection — as, for example, er^-sipelas — may not be qualified under ordinary conditions to produce another kind of infection — as, for example, an abscess. But avc observe such ready transformations in these varying degrees and qualities of virulence, and such modifications of the pathogenic eftects by other cir- cumstances than the virulence, such as the manner and site of invasion and the susceptibility of the individual, that it seems hopeless to attempt any division into physiological varieties on the basis of the quantity and quality of virulence, significant as this property is for our understanding of diverse streptococcus diseases in man. jNIany attempts have been made to establish different S](ecies or vari- eties of streptococci on the basis of morphological, cultural, and patho- genic differences. These attemjits have met with only ])artial success. They have tended to demonstrate the great variability of one and the same species, rather than to establish definite and constant distinctions between supposedly different species or varieties. So far, at least, as the streptococci which we ordinarily meet, and particularly those of interest for human pathology, are concerned, most authoritii's are of the opinion that no satisfactory division into separate species can at present be estab- lished, although it is convenient to classify streptococci according to certain jirominent but varying characteristics. The characteristics which ai-e most useful in this classification are those which appear in bouillon cultures. They are the length of the chains, the ]iresence or absence of cloudiness of the bouillon, and the kind of sediment jiroduccd by the growth of the cocci. We thus distinguish short-chained streptococci {streptococcus brevis), long-chained .streptococci (streptococcuti longus), streptococci which render Ijouillon cloudy and those which do not, streptococci which form Hoeculent or sandy or scaly or viscous sedi- ments. The uiimc strcpforoceus conf/fomcmtiis is given to a streptococcus which grows, without clouding the l)ouillon, in the form of dense, sep- arate particles, scales, or thin membranes at the bottom and sides of the tui)e, and on shaking the sediment it breaks up into little specks without producing unifiirm, diffuse cloudiness. On microscopical examination the chains in the latter case are long and interwoven in conglomerate masses. Streptococcus chains may be straight or wavy or twisted. These various distinctions are only of relative value. One firm may change into another. Virulent streptococci may be found among all the groujis mentioned. The streptococcus of erysipelas and most of the streptococci from abscesses and sejitica?mia grow in long chains in bouillon. MicrococcKs Tetragcnus. — Isolated by Koch and Gaffky (1S81) from phthisical cavities. Grows in tetrads enclosed in gelatinous capsules. Stains by Gi-am. Grows on all media at room temperature, with or 318 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. without oxygen. l<\irnis clovatcd, wliitc, n()ii-li(|iicf'vin(j colonics on gelatin. Pathogenic for mice, guinea-pigs, and, hy. intravenous and intra-jjcritoneal inoculation, also I'or ral)liits. Found not inf're(|Uently in ])lithisical cavities and sputum, oceasiouallv in association with ])yo- genic cocci in abscesses connected witli carious teeth and about the neck and jaws and middle ear, rarely in abscesses elsewhere. It has been considered to be non-pathogenic for man, but it has been found in pure culture in closed abscesses in man, and Yiquerat has proven experiment- ally that it is capable of causing stipjjuration in human l)eings. He considers that suppurations ])roduced by the tetragenus alone are mild in character, painless, with little reaction, easily cured. Boutron jjroposes the name " micrococcus tetragenus septicus" for the Koch-Gaii'ky micro- coccus to distinguish it from other similar tetragenous cocci. The latter are ncm-pathogcnic. Micrococcus Lanccolattis (Plate I., Fig. !j). — Synonyms : Diplococ- cus pneumoniffl, Pnoumococcus of Fraenkel and AVeichselbaum, Diplo- coccus lanceolatus. Micrococcus of sputum septieannia. Micrococcus pneu- moniiE cruposfe, etc. Discovered by Sternberg in his saliva in 1880. Demonstrated to be the cause of lobar pneumonia by Fraenkel and by Weichselbaum in 1886. Capsulatcd, lance-shaped coccus, occurring usually in ])airs and short chains, sometimes in long chains. Stains by Gram. Grows best at body tenijierature ; may grow at tempcratm-e of 18—22° C. Capable of cultivation on all ordinary alkaline media, but susceptible to slight variations in com]X)sition of culture medium. Colo- nies small, round, gray. Does not liquefy gelatin. Faculative anaerobe. Loses virulence and dies quickly in cultures. May survive in dried sputum or blood for four months. Killed in ten minutes at 52° C. A'^irulence and other properties extremely variable. Pathogenic for mice and rabbits, in less degree for guinea-pigs. Causes localized in- flammations and se])tic8emia. Present often in the mouth of healthy human beings (page 258). Next to the pyogenic staphylococci and streptococci, it is the most common cause of inflammations in human beings. It is probably the sole specific cause of genuine acute lobar pneumonia, and a frequent cause of broncho- pneumonia, otitis media, and meningitis. With or without pneumonia it may cause inflammation in any organ or part of the body. It can produce all kinds of inflammatory exudates — serous, sero-fibrinous, puru- lent. It most frequently invades the body from the bronchi or lungs, sometimes from the nose, nasal sinuses, and pharynx, and occasionally from the intestine. The list of diseases which it is capable of producing is a very long one, including inflammations of any of the mucous and serous memlji'anes, abscesses in an}- part of tJie body, mono- and jioly- arthritis, osteomyelitis, periostitis, parotitis, thyreoiditis, nephritis, acute ulcerative endocarditis, etc. It may cause septicsemia with single or multiple localizations. It is the most frequent cause of metapneumonic pleurisies, including empya-nia. Although it may cause the gravest dis- eases, it is ranked as a relatively lienign organism in comjtarison with the streptococcus pyogenes, particularly in pleurisies and suppurations. It may die quickly in inflammatory exudates, as well as in cultures, but it may also persist weeks and months. Micrococcus Pyogenes Tenuis. — Found by Rosenbach in pus (1884). BACTERIA OF SURGICAL INFECTIONS. 319 Has been described iu about twelve cases of suppurative inflammation. It is probably identical with the micrococcus lanceolatus (Neumann). Micrococcus Gonorrhoece or Gonococcuf! (Plate I., Fig. 4). — Discovered by Neisser in gonorrhcail pus in 1879. First cultivated by Bumm in 1885 on human blood-serum. Found constantly in gouorrJKval pus. The cocci are in jiairs, with tiie adjacent sides flattened against each other, with a clear interspace (biscuit shape). Grou{)s of four with adjacent sides flat- tened also occur. Particularly characteristic is the inclusion of the cocci ■within leucocytes, but they occur also free and attached to epithelial cells. Of diagnostic importance ii? failure to stain by Gram, which distinguishes the gonococcus from all the preceding cocci, but not from the so-called psendo-gouococci (pp. 2G6 and 207). Facultative anaerobe. Grows only at body temperature or neighboring temperature. Docs not grow on nu- trient gelatin or plain agar, or on the latter oidy with difficulty and occa- sionally. Grows best on a mixture of human blood-serum and nutrient agar (one to two or three parts) (Wertheim). The addition of sterile human urine improves the seruui-agar mixture (Steinschneider). Surface colonies pale, gravis]), translucent, finely granular, with finely notched borders. Forms a membrane in bouillon and Ijlood-serum mixed, leaving the fluid clear. Cultures on seriun-agar when prevented from drying may live forty-five days. Inocidation of pure cidtures into healthy human urethraj ])roduces typical gonorrhcea. The gonococcus is a strict human parasite. It dies (piickly in dried pus outside of the body. Virulence soon disap- pears, as a ride, in artificial eultiu'cs. The gonococcus is in general non-pathogenic for animals, but when inoculated witli bits of agar into the eye or into the peritoneal cavity of mice and guinca-jjigs it may cause suppurative inflannnation. In human beings its growth is usually superficial, and by preference on mucous membranes covered by cylindrical or transitional epithelium, but it may grow down deeply into connective tissue anil i)etween muscle-fibres, and may attack mucous membranes covered by Hat epithelium. It is the cause of most cases of salpingitis, pyosalpinx, and the accompanying peritonitis. It may produce genuine abscesses (ovarian, peri-urethral). It may be conveyed by the blood-current and cause inflammations in distant parts, most commonly arthritis, also endocarditis, pericarditis, pleiu'isy, and myocarditis. Every condition of rigid proof of the causation of artiiritis l)y the gonococcus (exclusive presence, isohition in pure culture, and experimental ])roductilump roils with roinided ends ])riivided with dis- tinct capsules in the animal body. Does not stain by Gram. Facultative anaerobe. Grows at room tem])(!raturc. Forms ])rominent, opacpie-white, non-liquefying colonies on gelatin. Grows on all media. Ferments glu- cose and lactose and produces gas-bubbles on jiotato. Pathogenic for mice, less s(» for guinea-pigs, and still less sn for rabl)its, which, however, may become infected by intra-peritoneal inoculation. Found occasionally 320 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. in tlie healthy human iiKnitli and nose, also outside of the hody. It is found most frecjuently in inilanunations of the mouth, nose, and middle car. It may cause broncho-])ucumonia, and has been observed in a very few cases of empyjema and of meningitis secondary to raiddlc-ear disease and to injury. It is a rare organism in this country. The badllus of rhinoaclerovut resembles closely the Friedliinder ba- cillus, and, according to some, there is no reliable differential character, not even the greater resistance to decolorization by Gram's method, which has been the point chietly emphasized. There is a group of capsulated bacilli, resembling the Friedlander bacillus/ some from human beings, others from animals, which have not been satisfactorily differentiated from each other (see page '2(J2). I>((ci/lus Pi/oci/anewi (Phite I., Fig. 2). — First cultivated by Gessard from blue pus (1882). A slender, motile, liquefying bacillus, decolorized by Gram, growing rapidly, even at ordinary temperatures, in all cul- ture media. In. the jircsence of oxygen forms bluish, fluorescent green and a whole scale of pigments. Interesting modifications of character, especially as to color production, can be produced artificially, and are observed under natural conditions, constituting, according to some writers, distinct varieties of the bacillus. Is widely distributed, occurring often on the human skin, in the fieces, and outside of the body. In wounds stains the dressings bluish green, and produces a somewhat characteristic offensive odor. Increases su])])uration of wounds, usually with little constitutional disturbance. I'atliogenic for animals. Is found not infrequently in perforative peritonitis and ap})endicitis, sometimes in piilegmons, otitis media, broncho-pneumonia, and inflammations of serous membranes, associated usually with other bacteria. It was found by Ernst in tuberculous pericarditis (Plate I., Fig. 2). Often found in diarrhoeal and dysenteric discharges. May cause general infections in human beings, ^yith or without general infection it may cause hemor- rhagic and necrotic enteritis, a form of ])yocyaneus infection in human beings which we have repeatedly observed at autopsy. Instances of invasion of the body from wounds by the bacillus pyocyaneus have not been observed. Bacll/i(f< Pi/or/enes Fa'ti(1i(.'<. — First cultivated by Passet from stinking pus of a perirectal abscess (1 885). Siiort bacilli with rounded ends. Cul- tures have a foul odor ; in other rcsj)ects they do not appear to differ from those of the bacillus coli communis. This bacillus probably belongs to the group of colon bacilli. It has been found in pure culture in closed abscesses, but more frequently is associated with other bacteria. Baeillm Coli Communis. — Isolated by Escherich from faces of infants (1886). There isS a group of bacilli, called the colon group, presenting similar characters, but with much variation in their cultural and other properties. Short rods with rounded ends, also longer forms. Either motile or non-motile. Do not stain by Gram in cultures or in the tissues, but do in normal stools. Grow at low as well as high temperatures on all media. Facultative anaerobes. Form large, spreading, grayish-white, non- li(iuefying colonies with notched borders on gelatin and agar, sometimes circumscribed, round, white colonics. On potato, brownish, yellowish, white, or even scarcely visible growtli. Coagulate milk, ferment glucose, lactose, and maltose." Constant inhabitants of the intestine, also widely PLATE 1.

The colon bacillus is a frequent invader of the internal organs in all sorts of diseases, especially when there are intestinal lesions. It manifests no evident i)atliogenie action in most of these cases, and is then \\itliout clinical signihcance. It occurs frequently associated with other bacteria iu infected wounds and other inflammations of exposed surfaces. Here also it does not usually appear to cause seri- ous disturbance. The fact that the colon bacillus is so common and widely distributed, and found so often as a harmless invader, should lead to mucii caution iit interpreting the significance of its presence when it occurs in definite lesions. There is no doubt, hiiwever, that it may be pathogenic for man. It plays an important role in inflammations of the urinary tract and biliary passages ; also, but usually with less independence, in peritonitis and appendicitis. The list of diseases in wJiich it may be found is a very long one, and includes inflannuations in all organs and parts of the body. Attention has already been called to its })atho- genic properties for man (page 274). In general these pro])erties are of a mild character. One of its leading roles is to invade territory already occupied by other bacteria or previously damaged. It may be concerned in the production of gall-stones, in the interior of which it has been found by the writer with great frequency. Its virulence as tested upon animals is variable, liut is generally manifest oidy after inoculation of large doses, which kill by intoxication rather than infection. Bacillus lactis ucrogenes is described by Esch-crich as shorter and plumper than the colon bacillus. Forms more circumscribed, elevated, Mdiite colonies, and coagulates milk and produces gas on ])otato more quickly and energetically than the latter. Predominates iu the upper part of the small intc^stine. Of late most writers include this bacillus iu the colon group, with which it corresponds in its general pathogenic characters. It is sometimes described as an opaque variety of the colon bacillus. Bacillus Typhi Abdominalis. — Mention is made of this bacillus, which is chiefly of medical interest, not to describe its characters, but to call attention to its capacity in rare instances to produce genuine sup])urative inflammations in man, and especially to cause periostitis and osteomye- litis as a sequel of typhoid fever. Most suppurations accompanying or following typhoid fever are due to the pyogenic cocci or are mixed infec- tions, but the tyjihoid bacillus may occur alone in abscesses. The most connnon post-typhoid osseous affection is periostitis with cortical ostitis. The exudate, when caused by the typhoid bacillus alone, may be dark and thin with much detritus, or syrupy in consistence, or genuine pus. The affection is oftener in the ribs than elsewhere, and may be obstinate toward treatment. ■ It may develop several months, and it has been claimed even years, after tyjihoid fever. Some observations indicate that the typhoid bacillus may cause meningitis and inflammations of serous memi)ranes. Bacillus Proteus. — In 1885, Hauser isolated from putrefying sub- stances the rapidly-liquefying profeus vulgaris, the slowly-liquefying proteus mirabilis, and the non-liquefying profeus Zenkeri, which he originally supposed to be three distinct species, but which he now regards on satisfactory evidence as three varieties of the same species, called bacillus jjroteus. The main characters of this bacillus are its Vol. 1—21 322 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. pleoniorphism, and especially movinjj, Avanderinii;, irregular projections and islands I'roni its colonies on gelatin and agar (swarming colonies). It is motile. This is one of the most widely-distributed bacteria, and is concerned in tiie decom]iosition of animal and vegetable material. It is not uncommon in the intestinal contents. Althougii repeatedly observed in iiiflanuiiations of exposed surfaces, in appendicitis, in ])er- forative peritonitis, and even in closed abscesses in association with other bacteria, it has been generally considered to be non-pathogenic for man, but our autopsy material has convinced us that it may be jiathogenic. It may be unassociated with other bacteria in abscesses and in periton- itis, and it may cause general infection l)y invading tlie blood and inter- nal organs (Flexner). In moderate and large doses it is pathogenic for animals. BaciUufi G^dcnudis Mulii/ni. — Long spore-forming l^acillus resembling the anthrax bacillus, but narrower and with rounded ends. Forms long threads. Strict anacrol>c. Ijicpiefies gelatin with gas-production and foul odor. Widely distributed in the soil and in the fjeces of animals. Pathogenic for animals. No instance is recorded of infection of a pre- viously healthy person with this bacillus, but Briegcr and Ehrlich have reported two cases of malignant oedema following the hypodermic injec- tion of musk in a typhoid patient. The bacilli were accidentally intro- duced l;)y the syringe. Bacillus Acrorioics ('apxiildfiis ; Bdcilbis Phlrf/mones EmpJii/scmafnsce. — An anaerobic bacillus first described by A\"elch and Nuttall in 1/i//ien"rt'.— Observed by Klebs (1883), first cultivated and accurately descrilied by Loffler (1884). Straight or slightly curved rods, averaging 1.2 to 2.6 /i in length, characterized especially by irreg- ularities in shape and staining. Particularly characteristic are swollen ends and deeply-staining chromatin-granules in the bacilli. Stains by BACTERIA OF SURGICAL INFECTIONS. 323 Gram. Not motile. Does not form spores. Facultative anaerobe. Optimum temperature for growth 33-37° C. Grows only slowly and slitriitly, if at all, below 20° C. Grows on all alkaline culture media, invisibly on potato, best on Loffler's blood-serum bouillon mixture. Does not liquefy gelatin. Forms on agar grayish-white, granular colonies with slightly irregular margins. In bouillon grows in the form of small grayish particles, with or without clouding of the medium, often with formation of surface membrane. Particularly important as a diagnostic critei'ion is the change of the alkaline to acid reaction by forty-eight hours' growth in bouillon containing carbohydrate. Thermal death-point, 58° C in ten minutes. May survive in some culture media eighteen months, but may die in three or four weeks. Lives longer in the dark than when exposed to light. Resistant to desiccation. jMay survive for three to five months in dry membranes, but usually dies sooner. Cultures dried on threads survive three to four weeks at room temperature. Both virulent and non-virulent diphtheria bacilli occur, the latter rarely in diphtheria. Pathogenic for many animals, and especially for guinea-pigs. By suhcutaneous inoculation there is pro- duced extensive local inflammation antl necrosis. The animal dies usually in thirty-six to sixty hours, with necrotic foci in various internal organs and serous transudates in the serous cavities. The bacilli are found only near the seat of inoculation or in very small number in the organs. With less virulent cultures or smaller doses subacute and chronic infections or intoxications ensue. Genuine pseudo-membranes, as a rule with little tendency to sjiread, follow inoculation of nuicous membranes superticially injured. The virulent diphtheria bacillus pro- duces by its growth in cultures or in the animal body a powerful poison, called the toxin or toxalbnmin of diphtheria, to which the constitutional symptoms, the lesions of internal organs, and the paralysis are due. The diphtheria bacillus is the cause of all cases of genuine diphtheria. Similar pseudo-mcml)ranous inflammations of the throat and air-passages may be caused by streptococci. The intensity of the affection caused by the dij)htlieria bacillus varies from a slight inflannnation without false membrane to the gravest pseudo-membranous inflanmiatious. The dipiitheria bacillus is incapable of attacking the intact skin. It may, however, produce pseudo-membranous inflannnations on excoriated, ulcerated, and wounded skin. Neisser has reported the case of a child five and a half years old with diphtheria of the throat in whom thick, firmly-adherent pseudo-membrane covered the skin alwut the anus over a sjiace 10 cm. long and 4 cm. broad. There was cedema of the scrotum and |)enis. L<)tfler bacilli were found in the false membrane and through- out the infiltrated corium. The localization of the diphtheria bacillus in cutaneous surfaces which have been deprived of the epithelial cover- ing by excoriation, eczema, ulceration, herjics, wounds, has been observed many times in persons afl'ected witli diphtheria of the throat, although it is not common. This localization may be attended by a pseudo- membrane, or by simple superficial necrosis, or by ordinary suppuration or inflannnation in no way suggesting diphtheritis. Park found diph- theria bacilli in two cases in wounds of the finger received by physicians in intubating children with di[)htlieria. They persisted for six weeks in one case. Wright has demonstrated the presence of this bacillus in 324 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. excoriated or ulcerated surfaces of the skin in 7 cases, in paronychia in 1, in mastoid abscess in 1, in ])urulc'nt ct)niunctivitis in 1, — all in cases of diphtheria. The dipjithcritic })rooess may extend by continuity to a tracheotomy wound. More freipiently the wciund is unatfected, even in cases where the diphtheria bacillus may be demonstrated upon its surface. Extensive necrotic and septic involvement of tracheotomy wounds is more frequently due to streptococci, with or without associ- ation with the diphtheria bacillus, than to the latter micro-organism alone. Brunner has reported three cases of infection of wounds with the diphtheria bacillus in association with pyogenic cocci in persons without demonstrable connection with other cases of diphtheria and Avithout any affection of the throat. In only one case was there pseudo- membrane. The presence of the diphtheria bacillus was not suspected in any of these cases before the bacteriological examination. In this connection a few words may be said regarding the general subject of wound diphtheritis, concerning which nuich confusion exists. Here, as well as in diphtheritis of mucous membrane, it is important to bear in mind that the term " diphtheritis " is a purely anatomical one, and implies nothing as to the causation of the affection. The term " diphtheria," on the other hand, should be restricted to the affection caused by the Loftier l)acillus wherever this may be localizi'd. There are three anatomical" conditions of a Mound to which the epithet " diph- tlieritic " has been applied — namely, first, the presence of an adherent fibrinous false membrane incorjiorated with underlying necrosis of the tissues ; second, the presence of a fibrinous pseudo-membrane loosely attached to the underlying tissues, which may present no distinctive alteration ; and, third, more or less extensive necrosis of the tissues of the wound without a distinct false membrane. Only the first condition is properly called diphtheritis ; the second may be called simple pseudo- membranous or croupous inflammation, and the third is necrotic inflam- mation. Wound diphtheria is infection of a M'ound by the Loffler bacillus. It may or may not be wound diphtheritis in the anatomical sense. Wound diphtheria may manifest itself as a simple inflammation, or inflammation with sujjerficial necrosis, or inflammation with more or less adlierent pseudo-membrane. Pyogenic cocci are usually associated with the L(')ffler bacillus in the diplitheria of wounds. Paralysis may follow wound di])htheria. As the same anatomical conditions in a wound may be produced by various causes, a positive diagnosis of wound diph- theria can be made only by bacteriological examination. The conditions as regards var'ying intensity and character of the infection, association with other bacteria, particularly streptococci, and the necessity of a bac- teriological examination to establish the diagnosis, are in no way differ- ent in the diphtheria of wounds from those in diphtlieria of mucous membranes. As has already been stated, wound dijihtheria may occur without demonstrable connection with cases of dijihtheria and without affection of the throat in the individual attacked, but such occurrences are rare. Diphtheritic, necrotic, and croupous inflammations of wounds are caused most frequently by other micro-organisms than the Lofiler bacillus. Here, as with similar inflanuuations of mucous membranes, BACTERIA OF SURGICAL INFECTIONS. 325 the streptococcus pyogenes appears to be an important causative agent, so far as can be judged from the small number of cases hitherto exam- ined bactcriologically. In this comparatively rare class of streptococcus infection of wounds the intensity and extent of the inflammation vary witiiin wide limits. It is not, or formerly was not, a particularly rare occurrence for coherent false membranes to develop upon granulating surfaces without notable disturbance in the process of repair and Mdthout constitutional disturbance. The membrane in these cases can be readily stripped off, after which another membrane is likely to form. It has been proposed to call tiiis relatively inoffensive wound complication " wound croup," in distinction from the more severe Avound diphtheritis. In two cases of croupous membranes on granulations Brunner found the streptococcus pyogenes in pure culture. In similar cases he and Tavel have found also the bacillus coli communis in pure culture. The condition may doubtless be associated with the presence of various micro-organisms, and is not, therefore, a specific one. In croupous inflammations of fresh wounds Brunner found the streptococcus pyogenes in association with other pyogenic cocci. How much the development of diphtheritic and necrotic inflamma- tions of wounds is influenced by the general condition of tlie patient is shown by the greater frccjuency of its occurnMice in persons pros- trated with typhoid fever, scarlet fever, septicaemia, pytemia, and other debilitating causes. Diphtiieritic inflammation of operative woimds involving the mouth and the bladder is more common than a similar affection of wounds in other parts of the body. The Loffler bacillus is not concerned, as a rule, with diphtheritis of these wounds, any more than it is with diph- theritic cystitis or enteritis. Much interest attaches to the question of the causation of hospital gangrene, that frightful sc(.)urge of pre-antiscptic surgery iu crowded hospitals, particularly in military hosjiitals. Hospital gangrene has been designated " wound diphtheritis," but it differs from the necrotic and diplitheritie inflanunatidus of wounds, which are now occasionally observed, in many features, particularly by its phagedenic eliaracter and its mortality. It has apparently disappeared, at least from civilized coiuitries, and there has been, therefore, no opportunity to make a bac- teriological examination by modern methods of any case of this disease. Although some of the older writers identified the cause of hos})ital gan- grene witli that of true diphtlieria, it seems, with our present Ivuowledge, highly im]irobal)le _that tliis is true. Our ol)servations of the effects produced by the diphtheria bacillus with or without association with other Ijacteria in wounds do not indicate that this orgtmism can have played any essential role in the causation of hospital gangrene. Some authorities are of the opinion that hospital gangrene is a s])ceific infec- tion tine to a specific micro-organism wliich has disappeared from civil- ized countries, as the micro-organism of tlic plague has disappeared. It seems to the writer more probable that it was due to pyogenic liacteria which still exist, l)ut whicli under the special conditions prevailing where hospital gangrene occurrcid had acquired a degree and kind of virulence with which we are no longer familiar. Thanks to antiseptic 326 (IKNERAL BACTERIOLOGY OF SURGICAL INFECTIONS. surgery, these special coiulitions aiv not likely to be repeated in civilized countries. BucaUus Tctuiii. — Observed by Nieolaier (1884) in wounds in cases of tetanus and demonstrated in garden eai'th, first obtained in pure culture by Kitasato (1889). Slender, straight bacilli, varying in length from sliort rods to long threads. iSluggishly motile. Splierical spores, tliirker than the rods, develop at one end of the bacilli, giving them a drumstick or pin shape, ytains by Gram. Anaerobic. Grows best at body temperature, slowly at 18-20° C, not at all below 14° C. Spores are formed in cultui'cs at body temperature in thirty hours, in cultures at 20° to 25° C, not until after a week. Grows in nutrient gelatin, whicli is slowly liquefied with slight gas production ; in agar and bouillon wJien free oxygen is excluded. Growth in gelatin is fuzzy, radiating, like a thistle. Dried spores live months and years. Cultures contain- ing spores dried on silk threads were found alive after several months by Kitasato. Henrijean demonstrated living, virulent tetanus spores on a j)iece of wood which had been extracted eleven years previously from the wound in a boy with fatal tetanus. The sjiores are killed in five minutes by moist heat at 100° C. They withstand in the moist con- dition for an hour a tem])erature of 80° G. — a jtrojierty ^\•hich \vas utilized by Kitasato to destroy other bacteria in obtaining pure cultures of the tetanus bacillus. The spores survive and jireserve their virulence for ten hours in 5 per cent, carbolic acid ; they are killed in fifteen hours. They are not killed by putrefactive Ijacteria. The tetanus bacillus is more or less pathogenic for nearly all warm- blooded and some col(l-l)looded animals. Infection takes place only through a wound. The period of incubation varies from a few hours to several days, according to the susceptibility of the animal and the dose. Experimental tetanus corresponds in all essential particulars to human tetanus. Tetanic s})asm appears first in the muscles nearest the seat of inoculation. Tetanus is a toxic infection. The bacilli multiply only in the imme- diate neighborhood of the wound, and do not invade the blood and organs. Inoculation with jiure cultures is a pure intoxication as a rule, with but little nuiltiplication of the bacilli, so that at the autopsy it may be difficult to find any bacilli. ^\nien imjnire cultures and foreign bodies are introduced into the wound the bacilli are more readily demonstrable at autopsy. There are no demonstrable lesions of internal organs in experimental tetanus. All of the symptoms of tetanus can be produced by the germ-free filtrate of tetanus cultures. It is the only infectious disease known every feature of which can be produced experimentally by injection of the poi- son without the micro-organisms. In the case of diphtheria all of the symptoms and lesions can be produced by the jjoison except the local false memlirane. This requires the presence of the liacilli. Brieger found in impure tetanus cultures foiu' crystallizable alkaloidal substances belonging to the class of ptomaines. Three of these he called tetanin, tetanotoxin, and spasmotoxin. He found also an unnamed base. As these ptomaines produced spasms by injection into animals, this residt was at first thought to indicate that the poison of tetanus had been iso- lated in a state of chemical purity. Subsequent investigations have BACTERIA OF SURGICAL INFECTIONS. 327 shown that these jitoinai'ne.s do not rci)ro(Uice all of tlic characteristic symptoms of tetanus. They are not the real tetanus poison, and no particular interest any longer attaches to them. The real poison of tetanus belongs to a different class of substances — namely, the so-called toxic proteids or toxalbumins, substances al)out ■which we know yery little chemically, but a great deal physiologically. We do not eyen know j)ositiyely tiiat the tetanus toxin is a proteid, but it is generally assumed to be. To this same class of substances belong the toxin of diphtheria, the venom of snakes, and certain poisonous sub- stances produced l)y vegetable cells, as ricin, abrin, robin. The specific tetanus toxin has been demonstrated both in cultures of the tetanus bacillus and in the bodies of animals. It has been found in the blood both during life and after death. It does not appear to be eliminated iu ap[)reciable amount by the urine unless very large doses are given. According to Kitasato, the poison is destroyed in the presence of water in five minutes at 65° C, in one and a half hours at 55° C ; it stands drying at ordinary temperatures ; is not injured by dilution with water or bouillon ; is sensitive to acids and alkalies. It is destroyed by the acid gastric juice. It is injured by exposure to light. So sensitiye is the tetanus poison to chemical reagents that Kitasato was unable to find any means of obtaining the poison in a condition approach- ing purity, and he expressed ignorance as to its real nature. Brieger and Cohn have, however, been more successful, and have isolated a substance possessing the properties of the tetanus poison in a condition approac^hing purity. As this sul>stance was found to be without most of- the proteid reactions, they consider that it is not an albumin in the ordinary sense of that term. The tetanus toxin is of appalling potency. Kitasato obtained liquid cultures of such virulence that 0.00001 ccm. of the germ-free filtrate, corresponding to 0.00023 mgm. of the dried filtrate, sufficed to kill a mouse with tetanus. ( )f course only a i)art of the dried substance is the real jxiison. Of tlie jiuritied substance obtained by Brieger and Cohn, who had at their tlisposal cultures of less primary virulence than those of Kitasato, 0.000,000,05 grm. killed a mouse of 15 grm. weight. As the fatal dose of the tetanus poison increases with much regularity in pro- portion to the weight of the animal, this would represent 0.23 mgm. as the fatal dose for a man weighing 70 kilo. When it is coiisidered that the minimal fatal dose of atropine for an adult is l.'>0 mgm. and of strychnine is 30-100 mgm., some conception of the terrible energy of this bacterial weapon can be obtained. The substance se])arated by Brieger and Cohn was not in a state of chemical j^urity. The tetanus poison, like the diphtheria poison, does not cause symptoms immediately after its introduction. With small doses it may he days before recog- nizable sym]>toms ap|)ear. This behavior is unlike that which we are accustomed to attril)ute to ciiemical poisons, and raises the question whether the poison may not be reproduced in the body, or whether the substance injected is itself the poison, and may not be in the nature of an enzyme which leads to the production of the real poison within the body. These (juestious cannot at present be answered. An interesting examjile of the effect of the pure tetanus toxin upon man is reported by Xicolar. In working with the filtrate of a tetanus 328 GENERAL BACTERIOLOGY OF SURGICAL INFECTIONS. culture he accidentally stuck the point of the needle of a hypodermic syringe containint;- some of the fluid into iiis left hand. Only the moist- ure adiiering to the needle was introduced into tiie puncture. After three and a half days the iirst symptoms of tetanus were manifested by contracture of the left thumb. There followed in succession contraction of the hand, the arm, then trismus, opisthotonos, general contractures, and convulsions. The treatment was by large doses of chloral. After three weeks improvement began, and recovery was comi)letc after forty- one days. In this uui(jue case the tetanus toxin was introduced in min- imal amount without the bacilli. Nicolar, in view of the fact that no symptoms were manifested until the third day, adopts the view that the culture fluid does not contain the real poison, but produces it by a kind of fermentation after introduction into the body. The distribution of the tetanus liacillus and the factors favoring infec- tion with tetanus have already been described (pj). 25.'j, 2(J5, 270, and 28!:l). Susceptible animals may be rendered immune from tetanus by the injection of the tetanus poison, at first weakened by chemical agents or heat, and then administered in full strength in constantly increasing doses. This is antitoxic inuniuiitv, already dcscrilicd, which has nothin<>: to do with natural imnuuiity. The hen is natui'ally immune from tetanus, but not by virtue of any antitoxic power of the blood. The blood-serum and other fluids of animals rendered artificially imnuuie from tetanus are capable, by virtue of their antitoxin, of rendering susceptible animals resistant to tetanus (passive immunity), or even of preventing the develop- ment of the disease or of curing the disease after reception of the virus. Bchring in 1.S92 reported that in the course of two years he had by suc- cessive injection of increasing doses of the tetanus toxin rendered a horse so highly immune that the immunizing value of its blood-serum was 1 to 10,000,000, by which is meant that TTiWoTrTTotli fcm. of serum will protect 1 grm. weight of mouse from the effects of the subsequent injection of the smallest fatal dose of the tetanus poison, or 1 ccm. of serum suffices to imnuuiize 5()0,(l()0 mice, weighing each 20 grams, or 200 shee]>, weighing each 50 kilo. When, however, the attempt is made to prevent the develop- ment of the disease immediately after the reception of the virus, a larger quantity of the serum is required to afford protection than a few hours previously, and as time elapses the amount of scrum required rajiidlv increases, until, as soon as the very first symptoms of the minimal fatal dose of tetanus poison appear in the mouse, one thousand times the quantity of serum necessary for simple preventive imnumization must be injected. After twenty-four hours the necessary quantity of serum possessing an immunizing value of 1 to 1,000,000 is too great to be intro- duced into the animal. To produce the same curative effects in large animals as in small it is necessary to inject jiroportionately larger amounts, the dose being in approximately direct ratio to the respective weights of the animals. These considerations manifestly suggest serious difficulties in the application of the antitoxic treatment of tetanus to human beings. But there is another difficulty of probably greater force — namely, that we have no indication that tetanus will result from a woimd in man until characteristic symptoms have appeared. By that time tetanus poison has accumulated in considerable amount in the system. Kitasato was unable to prevent the develojjment of tetanus in mice by the com- PLATE I I. ^ il // ■*^ v1" •# \ ^V 1\ lU' II I -}l V Tubercle bacillus and streptcicocci in s])Utum (p. 329). Abbott.

It is not positively proven that cura- tive antitoxic serum neutralizes poison which has already been received into the system before injection of the serum, although it is capable of neutralizing poison formed after its administration. \Ve stand in a much less favoral)le position for tiie successful treatment of human tetanus by antitoxin than is tiie case with diphtheria, where the conditions are more favorable both as regards progressive increase of dosage in proportion to the weight, and especially as regards the possibility of beginning treat- ment before the absorption of large quantities of the poison. These are the scientific considerations relating to the treatment of tetanus by anti- toxin. Its practical a]>plication and the results of treatment in human beings belong to the article on Tetanus in this work. Baci/las TiihciTulosis. — Discovered and first cultivated liy Koch (1882), independently and at about the same time demonstrated microscopically in tubercles by Baumgarten. Slender, straight, or slightly curved or bent, non-motile rods, 1.5 to 4 // in length, which averages live to six times the breadth. In unstained specimens glistening dots, in stained speci- mens clear spots, are often seen in the rods, which thereby j)resent a beaded appearance. Tiiese are interpreted by Kc)ch and others as spores, but this has not been proven. Xo greater resistance to heat and other injurious agencies has been demonstrated for bacilli containing these sus- pected spores than for l)acilli without them. Tubercle bacilli take up staining dyes with difficulty, Imt when once thoroughly stained by intense aniline dyes they retain the color after it has been extracted by acids, alcohol, and other dec9), and will be further considered in the articles treating of the various forms of surgical tuberculosis. The bacillus of avian tuberculosis is a different species, or at least a different variety, from that of human tulicreulosis. Bacilhis Lcpnr. — Discovered l)y Hansen (1879) in leprous tubercles. Morjiliologieally, the le])rosy liacillus resembles very closely the tubercle bacillus, from which it probably cannot be distinguished in size and shape. It presents clear, unstained dots like those observed in tubercle bacilli. It resembles the tubercle bacillus also in its staining reactions, the only important difference being that it is more readily stained by aniline dyes than the tubercle bacillus. It stains well by Gram's and A\'eigert's fibrin stain. It is non-motile. Although many observers claim to have cultivated the leprosy bacillus, none of these claims have been established, at least not to the satisfaction of most bacteriologists. Most experimenters have had only negative results from the inoculation of leprous material into animals. The positive results rejwrted by Damsch, Vossius and ]\Ielcher, and (Jrtman are o])en to criticism in their interjire- tation. The apparently successful inoculation of a condemned criminal in the Sandwich Islands by Arning has also been criticised as not con- clusive. The constant and exclusive presence of the bacillus lepra in leprosy cannot be reasonably interpreted otherwise than that the liacillus is the cause of the disease. The characteristic bacilli arc present in enor- mous number in the lejirous nodules, being chiefly enclosed within cells. They have also been found in the lesions of the disease in all parts of the body. They are very rarely in the blood. BacUliifi Mallei. — Discovered by Loffler and Schlitz (1882) in the lesions of glanders. Somewhat shorter and thicker than the tubercle bacillus. Presents often clear, unstained s]iaces in the rods. It probably does not form spores. Decolorized by (xram. Stains with the usual aniline dyes, but is so easily decolorized that its demonsti-ation in sections is somewhat difficult. Like the typhoid bacillus, it occurs in the tissues especially in clumps. Non-motile. Facultative anaerobe. Grows best at body temjierature, but is capable of growth at room tcmjierature. Grows on all culture media, but, as has been shown by Theobald Smith, far better on acid (non-neutralized) than on alkaline media. Particularly characteristic is the growth on potato, on which the glanders bacillus BACTERIA OF SURGICAL IXFECTIOyS. 331 forms at first a transliict'iit, amber-yellow layer, later a reddish-brown layer with discoloration of the potato. Growth on agar whitish, moist ; if the medium be acid, thick and abundant. The virulence diminishes in successive generations in artificial cultures. The glanders bacillus may survive in the dried condition for three and a half months, but usually dies within two or three weeks. There arc t)l)scrvations which indicate that it may survive for at least a year and a half in unoccupied, infected staliles. By inoculation of horses with pure cultures glanders is pro- duced. The bacillus is pathogenic for several species of animals. The guinea-pig and the field-mouse are particularly susceptible. White mice are resistant. The field-mouse dies from experimental inoculation usually in three or four days with acute infection and miiuite tubercle-like nodules in the spleen and liver. The lesions in the guinea-jiig arc most characteristic, consisting in a caseous ulceration at the scat of subcutaneous inoculation, which, however, is often absent; swelling and necrotic sup- puration of the testicles ; swelling and idceration of the joints ; and nodules in the spleen and liver, sometimes elsewhere. The best method of diagnosing a suspected case of glanders is to inoculate the material into the peritoneal cavity of a male guinea-pig. In four or five days, at the most in eight or ten days, the characteristic swelling and infiannnation t)f the testicles can be detected. The bacilli arc in the lesions, but scanty or absent in the blood. Mallcin is a product derived from cultures of the glanders bacillus, and is analogous in its properties and uses to tuberculin derived from the tubercle bacillus. It is used for the diagnosis of glan- ders in animals, as tuberculin is used for the diagnosis of tuberculosis. Bacil/itx Aiithrdcix. — Discovered in the blood of animals affected with anthrax by Pollender (1849) ; also observed by Davaine (1850), Eayer (1851), and Brauell (1857). The studies upon the anthrax bacillus laid the foundation-stone of modern bacteriology. The bacil- lus is 1 to 1.5 II broad and 3 to 10 // long. It grows out into long threads made up of bacilli, the adjacent ends of which are sharply cut and slightly concave. Not motile. Stains readily with aniline dyes, including Gram's stain. Forms spores in the presence of oxygen, but never within the animal body. Grows at room temjjerature, best at body temperature; does not grow below 12° C Grows on all culture media. Li(]Uefics gelatin with moderate rapidity. Colonies on gelatin are whit- ish, often with fuzzy, irregular, hair-like projections. Similar bristle-like projections often characterize the growth in the bne of i)nncture in gel- atin and agar. Desiccated spores may survive for years. Anthrax spores are usually killed in four minutes by boiling temperature, but they vary in their resistance, and may withstand boiling temperature for twelve minutes (von Esmarch). Some anthrax spores are killed by 5 per cent, carbolic acid in two days ; others survive for forty days. Various modifications of character of the anthrax bacillus can be ])ro- duced by cultivation at high temperatures (42—43° C.) or by the addi- tion of dilute antiseptics, the most Imjiortant modifications being the production of an as]iorogenic variety of the bacillus and the loss of virulence. Any degree of attenuation of virulence can be produced down to com]ilete loss. These attenuated cultures serve as vaccines to rcnr sanguinis, which stinudatc growth and excessive prolifcratiy pressure, or perhaps tender- ness only, is complained of, rather than acute pain. While slight increase of heat may be noted, often there is no local rise of temperature. Swell- ing is always well marked and detectable if the part be not too deeply seated. Constitutional symptoms, as fever, are sometimes alisent, espe- cially if no important organ is involved, but the patient is usually out of health, and may present evidences of syphilis, rheumatism, gout, or tubercle. The possible terminations of chronic inflammation are resolu- tion, sujipuration, or ulceration, chronic induration or thickening, casea- tion, and calcification. ULCERATION AND ABSCESS. 343 Treatment. — All secoiulary causes of irritati(in must he removed, the dilated vessels with their sluggish current promoting constant escape of leucocytes, and the formation of a low grade of interstitial connective tissue — *. e. scar-tissue — must be stimulated to contraction. The nutrition of the tissues should be ])rom(ited by the access of arterial blood and the free return of the venous blood, and means sliould be taken to promote the absorption of intlammatory exudates. Sup[)orting pressure will reduce the size of the vessels and induce atrophy of the poorly-organized exudate. Massage will break down exudates, force the cells into the sur- rounding lvmj>h-spaces, increase the arterial afflux, and favor the venous efflux. Aiteruatc hot and cold douches are also valuable vascular stimu- lants. Counter-irritation l)y l>listers, the actual cautery, etc. is of value if employed upon tiie contiguous vascular areas above or below the part, but can only jjro\'e harmful \vhen applied to the part itself. Improve- ment of the general health by appropriate remedies and attention to any goutv, rheumatic, tubercular, or syphilitic taint is essential to success. Gener.\l Considerations. — Ulceration and Abscess. These processes are always the result of microbic infection interfering with the normal processes of repair, the so-called " plastic inflammation," which results from the injury of aseptic tissues, provided their vitality be not at once destroyed. All su|)purative processes are essentially de- structive, resulting in loss of tissue. A\'hen such microbic inflammation takes place upon a free surfiicc, as a cutaneous or mucous membrane, loss of substance occurs by molecular destruction of tissue, the processes which produce this being called " ulceration," and the resultant area of inflamed tissue which has suffered loss of substance is called an " ulcer." All ulcers heal by the organization of granulations which become covered by epithelium. When primary iniion fails or when sloughing results from traumatism, tlie term "ulcer" is aj)p]ied to any granulating surface left, because healing takes place by the same proces.ses. Although the pathology of inflammation and suppuration will receive extended notice elsewhere, it is essential here to describe briefly certain portions . of these ]iroces.ses, that the reader may comprehend what follows. From the ))resence of microbes at the outset, or because of their sec- ondary implantation at the focus of inflammation, the tis.sues at this spot become so crowdcil with exudates that they are practically replaced by masses of young cells, anil the vessels are thrombosed, so that a return to the normal state is impossible unless a new vascular supply enables the cells of the exudate to develop into a permanent tissue. In the normal reparative processes- nutriment from the surrounding vascular areas reaches the most centrally located cells, passing from cell to cell or be- tween them, tile cells Ix'iug held in contact by the intercellular material until vascular loops interpenetrate the exudate. The presence of microbes changes all these processes. The resultant peptonizing ferments or the ptomaVnes cither attack the vitality of the cells, or, by disassociating tiicm t)y dissdlving the intercellular cement, })ut tlicm into condition to undergo fatty degeneration, to die, and to become suspended in a fluid, the /itjuai- puriK, composed of exuded serum, lique- fied intercellular cement, and exudate. When these processes are very 344 DIAGNOSIS AND TREATMENT OF ABSCESS. rapid small areas of tissue beeonio surrounded by others so tii<)roiii;hly infiltrated with cells that upon their st)lution into pus these conipara- ti\-ely unaltered fragments are seen floating as shreds in the ])us. \\'hen this occurs upon a free surface a variety of sloughing ulcer results. AVhile many forms of microlx's have at times proved to he j)yogenic, the most common varieties found in acute abscesses are the ytiijiliiilo- coccus pi/of/ciici aureus and a/bus. The fact that these germs tend to aggregate into clusters (hence their name) would seem to exjjlain the circumscribed chai'acter of the suppurations they initiate. A marked difference is usually noticeable in ]iurulent conditions induced by strep- tococci. These germs rapidly become diffused through the tissues by way of the lymphatics, and are therefore apt to originate diffused sup- puration. That microbes are the cause of suppuration would seem to be contra- dicted by the occasional failure to find them in cold abscesses, but the explanation of the ajjparent exception is twofold : either that they were present earlier, but died from lack of pabulum or self-poisoned bv their own excreta, or that in the given instance the tubercle l)aeillns acted as a pyogenic organism; which is unciuestionably, although rarely, true. Again, however closely it may resemble pus, the fluid contained in many cold abscesses is not pus, but liquefied caseated tubercle, no pus-cells being discernible. Local sujipuration can be promptly and certaiidy produced by the inoculation of ordinary pus-germs, as liy rubl)ing pure cultures into the intact skin. The fluid resulting from the injection of aseptic chemical substances, such as turpentine, croton oil, etc., is puruloid, but is not pus. It is merely a fibrinous exudate containing numerous cells ; is only seen when exceptionally favorable laboi'atory conditions are secured ; shows no tendency to spontaneous evacuation, as true pus does, because the solvent action of the peptonizing liacterial ferment is absent, which also prevents the coagulation of new exudate ; and finally, is never found clinically. Again, the injection of a jitomaine into the tissues merely reproduces the conditions which would be furnished if bacteria were present. Predisposing- Causes. — Abscess being a result either of primary or of secomlary microbic inflammation, those ccmditions which experience has .shown to predispose to this variety of inflammation nnist favor pus-j)ro- duction. Local conditions which lower the vitality of the tissues, and general impairment of nutrition, however effected, favor microbic inflam- mation. Temporary slowing of the circulation from accidental causes, especially when aided by anatomical conditions, favors localization of microbes. Thus a trivial contusion of the medulla of bone, rupturing a few vessels in which thrombi form, produces a collateral hyperemia which produces a slowing of the circulation, so that mechanically — being heavier than the blood-cells — the germs accumulate. The tortuosity of the medul- lary vessels, and in consequence the sluggish current flowing through them, favor microbic implantation, so that exjiosurc to cold, driving the blood from the surface, may cause such additional dilatation of the vessels as to determine an accumulation of germs if they have gained access to the circulation by any distant infection-atrium. General Symptoms of Abscess. — Pus-formation is so often pre- ceded by a chill or rigor that when this occurs during an attack of local- ACUTE ABSCESS. 345 ized inflammatioii it is too commonly vicwi'il as a oonelnsive symptom, es- pecially if the fever which results is followed by a second chill. This idea is erroneous, as in some individuals, especially when certain parts or organs are involved, the chill may he only indicative of the thorough establish- ment of the intlanimatory process or the sudden involvement of a new area : again, all malarial poisoning nuist be excluded. Fever will be present in varying degrees, witli its concurrent anorexia, coated tongue, dry skin, confined bowels, and scanty urine. In some individuals de- lirium may be present ; but all these symptoms, it must be remarked, are not those of abscess specially, but of the inflammatory process which is terminating in sujtpuration. As the thoroughly infiltrated focus dissolves into pus the peripheral area, just about to be converted into granulation tissue by the ingrowth of capillary loops, is attacked by the ingrowing germs and tlieir solvent ])roducts, and breaks down into pus, thus enlarging the abscess-area. This futile attempt at the formation of gramdations usually goes on until nature or art evacuates the abscess, when, the tension being relieved, the excessive vascularity disai)pears, the perijihcral layer of granulations becomes perfected, the cavit}' collapses, the apposed sur- faces fuse, and, epidermis forming over the skin-orifice, cicatrization is completed, the granulation tissue becoming converted into connective tissue ; i. e. a subcutaneous contracting xcar forms. When the jn-ocesses are slowcn-, or from any cause the ])vogenic organ- isms lose tiieir virulence, the peripheral layer of intiltratctl tissue becomes converted into granulation tissue, but from the non-evacuation of the pus is prevented from fulfilling its normal function — viz. conversion into fidly-formed but low-grade connective tissue ; this process stops halfway, the deeper layers undergoing this change, while the superficial remain here and tliere as scattered, ill-formed granulations : this mem- brane-like structure is the miscalled pyogenic membrane. Acute Abscess. The causation, pathology, and mcth(^d of healing must be sought in the section on Inflammation. Symptoms. — During an acute inflammation the process becomes more localized at one point. Throbbing ]iain is felt, and a chill often occurs when pus forms. If superficial, the inflammatory redness and swelling become more circumscribed ; palpation discovers central soften- ing and fluctuation : this spot becomes more ]5ronnnent — /. c. ])ointing takes place. The skin, becoming j)urplish, glazed, and thinned, gives way, either after the- sejiaration of a slough or by ulceration following the formation and rupture of a bleb of cuticle. A deep-seated absces.s is shown by oedema, mottling of the skin, tenderness, and localized induration, or a sense of resistance of the deeper parts, with obscure fluctuation ; fever, and probably rigors, having preceded these symptoms. When in doubt the grooved needle nnist be emjiloyed. Treatment. — Up to the time of incision or rupture warm jioultices will hasten the process and limit its extent, but when about to be spon- taneously evacuated moist antiseptic dressings must be substituted. Pus should always be early evacuated by incisions made at the mo.st depend- 346 BIAGNOSIS AND TREATMENT OF ULCERS. ent part to facilitate drainage if no important s^tructnrcs are in the way. Snch incisions must be free, and should l)e followed l)y the introduction of drainage-tubes. Sometimes counter-openings are advisable. Pus ought to be allowed to flow away, because pressure will rupture granulations, the only barrier against absorption of noxious })roduets. Subsequently, antiseptic dressings must be used— never a poultice. Pus is always de- structive, causing absorption of the tissues as it pursues the line of least resistance, and may open into joints, nnicous canals, etc. ; hence, when in the perineum, near the peritoneum, in a tendon-sheath, beneath tense fascia, or compressing a canal, as the trachea or urethra, especially prompt intervention is demanded. In exposed parts the sear of an incision is less unsightly than that following Nature's efforts. When pus deeply underlies important vessels or nerves a small incision through the skin and fascia should be made, the tissues bored through with a grooved director until pus is reached, along this instrument a pair of dressing-forceps be introduced, closed, and withdrawn partly opened, thus lacerating the structures without risk to arteries or nerves ; a drainage- tube can then be inserted. This is " Hilton's method." Rarely, from loss of support, severe venous hemorrhage follows ojjening an abscess, or later a large vessel — vein or artery — ulcerates. [So-called chronic or cold abscess, being really a tubercular process, will be treated of in another part of this work. Ulcers. As already stated, an ulcer is a solution of continuity, situated upon the skin or a mucous membrane, jtroduced by molecular loss of sub- stance, sometimes increased by sloughing, the result of microbic in- flammation : any granulating surface left after accident or operation is also called an " ulcer." Although ulcers may be described as belonging to one or other of certain classes, accidental conditions may cause them to change their characteristics. Ulcers are divided into those where the characteristic appearances are due to local conditions, and those resulting from specific or constitutional causes. In this section we arc concerned with the first class only. Simple Healthy or Healing Ulcer. — As every ulcer must attain this condition as it cicatrizes, the appearances of this form of ulcer must be carefully studied, all non-specific ulcers being mere varia- tions from this type, the result of ol)staeles to Nature's attempt to heal by the organization of granulations and their covering over by epi- dermis. The margins are smooth, shelving down to a level base, which is cov- ered by healthy granulations moistened -with a small quantity of creamy, inodorous pus. The surrounport to the circulation — /. e. pres- sure. Solutions of sulphate of cojipcr (gr. j-x to fsj), sulphate of zinc or nitrate of silver in the same strength, sterilized oxide-of-zinc oint^ ment, with occasional use of the solid stick of nitrate of silver, and sometimes compression effected by a roller bandage, usually suffice. The CEdematous Ulcer. — Employ wet dressings or prolonged ])oulticing, especially with a feeble venous circulation in the part, and, although the margins of a previously healing ulcer may remain fairly healthy, the granulations will become swollen, flabby, pale, semi-translu- cent, and friable from aKlema, and will extide much watery pus. Treatment. — Here more blood, and blood circulating at a proper iiite, is demanded ; hence stinudant ajjplications, as grs. v-x of chloral to .y of water, resin ointment, l>alsam of Peru, or some astringent, and meclianical support, are indicated. The Inflajimatory Ulcek. — Let certain individuals indulge freely in alcohol, especially if previously ill-nourished and improperly fed dur- ing their drinking-bout, and a traumatism which would in others, or even in them under more favorable circumstances, produce an ordinary ulcer, often will residt in a ra]Mdly-enlarging ulcer of irregular form, having sharp-cut or ragged margins, the Itase formed of the red, inflamed tissues freely secreting a sero-sanguinolent discharge, which often contains shreds of tissue. If the inflanmiation is hyperacute, the base of the ulcer may be covered with yellowish sloughs. The circumjacent skin is inflamed and cedematous. Inflamed Ulcer. — When a ])rcviously healthy ulcer is irritated, neglected, and dirty, especially in drinkers, inflanunation may attack the granulations, which become red and swollen, and slough ; the margins break down, the ulcer spreads, and the surrounding tissues present the ordinary phenomena 'of inflammation. Treatment. — Removal of all local irritation, elevation of the parts, warm, moist, unirritating antiseptic lotions, as of boric acid, or, better, when feasil)le, the continuous warm antiseptic bath, are indicated. Drinking should be stopped, more food and of a better quality must be provided, and the eliminative organs stinudated. This combined local and general treatment will usually soon convert either the inflanunatory or the inflamed ulcer into a simple one. The Sloughing Ulcer, except when this term is applied to the worst cases of the varieties just described, is rarely seen except in con- 348 DIAGNOSIS AND TREATMENT OF ULCERS. nection witli venereal disease in those broken-down by ak'ohol and sexual excesses. In such patients destruction of parts ])r()grcsses with great rapidity. The cellular tissue is more extensively dcstmyed than the skin ; hence the edges of the ulcer are undermined and inverted, and of a dusky-red hue, the base being covered with gray (ir black sloughs. Tliere is great pain, and severe constitutional disturbance is the rule. Treatment. — This docs not differ from that of the inflamed ulcer, except that anodynes will be required to relieve pain, and, as svpliilis is often present, mercury must be used with a sparing hand or be entirely withheld. Tonics, good food, and stinndants will often be requisite. The Phagedenic Ulcer is believed to result from the multipli- cation of a specific micro-organism in the tissues of those broken down by intemperance, bad food, etc., and is usually of venereal (chancroidal) origin. The surrounding skin is of a dusky-red or ])urplish hue. The margins of the ulcer are ragged and uudcrmiiUMl, tiie l)ase is covered with bloody discharge and sloughs, and when tiiis last condition is pro- nounced what is termed a " sloughing phagedena " results. The tissues melt away with astounding rapidity, the external genitals of the male or female sometimes being totally removed. Great pain and high fever are the rule. Treatment. — As infection by a virulent organism is the cause, thor- ough destruction of the surface and margins of the ulcer, with some of the adjacent tissues, must be effected by strong nitric acid, bromine, or the actual cautery. In the milder forms disinfection with a 1 : 1000 corrosive-sublimate solution, followed by the free use of iodoform, may suffice. The continuous warm antiseptic bath may supersede or supple- ment other methods. Opium, tonics, stimulants, and good food are imperatively demantled, with improvement of the patient's hygienic surroundings if these be poor. Indolent or Chronic Ulcer. — Let any granulating surface have its healing processes repeatedly interfered with bj' mechanical or other irritatiiin, and, while the formation of epidermis is prevented, the em- bryonic tissue forming the margins and base will develop into dense filn'ous tissue, fixing them to the subjacent fascia, periosteum, or lione. This is aided by a weak venous circulation, favoring congestion, which condition of the circulation may result either from a feeble heart, vari- cosity of the veins, the dependent position, or all combined. In addi- tion, the contracting cicatricial tissue cuts oft' much of the arterial supply, preventing the formation of healthy granulations. Healing is also seri- ously interfered with Ity cicatricial fixation of the margins and base of the ulcer, for, as will be explained (see p. 368), much of the healing of any granulating surface depends upon diminution of its superficial area by contraction of the deeper layers of granulation tissue, which fixation of the base to the deeper structures absolutely prevents. These points must be kept in view as governing thei'apeutics. Symptoms. — The lower third of the leg is the favorite position, and the poorer classes the victims. The edges are smooth, rounded, much elevated, insensitive, while the circumjacent skin is bronzed or purplish : eczema is quite common. The base has few if any granulations, and these are scattered, pale, and flabby, and covered with an oftentimes very ULCERS. .349 offensive thin, piiruloid, or sanious discharg'e. Usually hut little pain is experienced. When left untreated they last for ten, twenty, thirty, or forty years. Certain of these ulcers, if subjected to constant irritation, undergo an epithelioniatous change, and are then known as " jNIarjolin's ulcer.'' Treatment. — This must depend ujjon the conditions. If access of arterial lilood is prevented by the cicatricial margins, radiating incisions through these may be made, a fly blister may l)e applied covering base and margins, tincture of iodine may be similarly employed, or ati'ophy be induced by the pressure of an elastic l3anic'reing tlie bones "as if tlicy liad hecn drilled," their osseous walls are often unaft'ected with the degeneration, and that they open into single or multi|)le rounded cavities eontaining numerous granides, which latter are likewise scattered over the sinus-walls or arc free in their luniina. The lighter granules consist of a central close mycelial netw()rk "and a peri- peripheral fringe of more transparent, more or less glassy, rays." The black granules are chiefly formed of the inorganic constituents of the tissues, ]>igment, and the more or less altered fungus. Symptoms. — The j>art attacked is nearly always the foot or leg, next in frequency the hand or arm, ^'ery rarely the shoulder or scrotimi. The onset varies. Thus, a toe or finger, or the foot itself, may l)e attacked, very little swelling, redness, or circumscribed induration being noticeable. Again, either a superficial or deep ]ia])ule, pustule, or tubercle may ap- pear, moderately tender, which on rupturing discharges pus, but later the characteristic granules. Occasionally a subcutaneous mottling exists for some time before the skin gives way. Slowly, accom])anied by severe pains, the foot becomes enormously swollen, distorted, and useless ; the arch of the ibot gives way from destruction of the bones, so that even over-extension of the toes takes place. Scattered over the skin are small elevations, whose centres are the orifices of the sinuses leading into the cavities before mentioned. These latter may be near the surface or deeply seated, and sometimes involve the lower ends of the tibia and fibula as well as the bones of the foot. The discharge is sero-purulent, and con- tains the characteristic white, yellow, black, or very rarely pink or red granules resembling fish-roe. The granules also lie scattered on the sur- face around the orifices of the sinuses. It may take six to twelve years completely to disorganize the member, but the disease tends to a fiital termination. Diagnosis. — Commencing as a tubercle or pustule, until either rup- tures it might be difficult to decide between mycetoma and the Guinea- worm disease, but the absence of the worm and the roe-like material in the discharge would settle its nature. In advanced cases the fact of an extremity being concerned, the marked swelling, the numerous sinuses, and the characteristic granular discharge should suffice. Prognosis. — If left to nature, complete disorganization of the mem- ber will result. Treatment. — When superficial, early free curetting has proved effi?et- ual. If only a finger or toe is involved, its prompt removal will usually suffice. In more advanced cases amputation is the sole resort, and, as the leg-bones niay have undergone change much higher than external appearances would indicate, the bones must be removed well above any suspicious point. Pernio, or Chilblain. This is produced by the sudden ap])lication of cold to any exposed portion of the body where the circulation is impaired. The vascular condition maybe due to a weak heart or to the distance of the part from the centre of the circulation, as in the case of the ears or toes. In the latter instance the compression of the foot-gear also favors antemia. Sudden aj)proach to the fire after exposure is a common cause, owing to the change of tempei'ature causing intense congestion from vasomotor FROST-BITE. 355 paresis. Cliildren ^vhose power of g;enerating heat is feeble, and those adults who resemltle them in this particular, are most lialile to chilblain. Symptoms. — The mild form amounts only to a moderate redness of the skin and some swelling, with hi'at and itching of tiie parts, which dis- a])pear spontaneously. Another variety is evidenced l)v marked swelling and redness, the latter often assuming a purplish hue due to venous con- gestion. The heat, itching, and tingling pain are very marked, especially when the parts become warm after the slightest chilling. This form usuallv does well with proper treatment. In its worst form pernio closely rcsendiles frost-bite from the severity of the inflammation, blebs forming which on rupturing leave indolent ulcers, sometimes covered with sloughs, " yielding a thin ichorous or sanious discharge." Treatment. — Prophvlaxis is important, and consists in woollen cover- ings for the feet and appropriate ones for the hands and exjiosed parts. Local stimulation of the circulation by dry frictions or with alcohol, spirits of camphor, or soap liniment is useful as a i)rophylactic. Entei- ing a warm room or coming close to a fire, even after exposure to slight cold, must be avoided. When the milder form is threatened gentle fric- tion with snow or ice-water until reaction begins to be established, in a cold or only moderately warm room, is to be rcconnnendcd, followed by an alcohol dressing, or even tincture of iodine when no Idisters have formed. AMicre jjcrsistent congestion with tendency to swelling, attacks of itching, etc., repeatedly occur, the constant current and local applications' to produce contraction of the paretic vessels, coupled with tonics and measures calculated to invigorate the circulation, will usually give relief. If ulceration or sloughing occur, it must be treated ujjon general principles. Frost-bite. This term includes the more serious effects resulting locally from the abstraction of heat — miscalled " application of cold." Exposure to low temperatures causes destruction of jiarts in two ways — /. e. (1) directly, by freezing the tissues so thoroughly and for such a time that, even when most cai'efully treated, after thawing they are found to be dead ; and (2) more connnonly indirectly, gangrene resulting partly from the lowered vitality, but chiefly from the subsequent inflanmiation, causing strangu- lation and death of the enfeebled tissues by the exudates ; in other words, so-called " inflammatory gangrene " determines the sloughing or sphac- elus. The effect of cold being to promote adhesion of the leucocytes, cajiillary thromboses are readily formed, favoring and often determining gangrene. Symptoms. — First, numbness with loss of power is felt, usuall}' in peripheral parts, as the nose, ears, fingers, or toes ; then tingling and a sensation of weight are noticed. Inspection now shows that the parts are bleached white and icy cold to the touch, all sensation being lost. If ho])elessly frozen, discoloration and swelling follow the ]irimarv blanching ; the parts next shrivel and contract ; a line of separation fol- lows ; putrefactive changes ensue ; and the nose, ears, feet, or hands may 'Camphorated soap liniment, turpentine witli copaiba, lead-water, alum in solution, with numerous similar suhstances, have been all vaunted, but careful prophylaxis is requi- site to render any treatment of avail. 356 SYMPTOMS AND TREATMENT OF GANGRENE. be spontant'ou.sly amputated. When too rapid tliawing jw'ecipitates gan- grene, or judicious eif'orts fail to maintain the vitality of the part, the primary swelling and ah)iormal sensibility are followed by intense in- flanniiatory phenomena ; blebs form ; tiie pain ceases; the skin becomes mottle(l and discolored ; and finally the parts manifest all the phenomena of moist gangrene. Treatment. — This nnist secure a most gradual restoration of circula- tion, and with this the power of (calorification. Sudden increase of temperature will induce such a paretic condition of the vasomotor sys- tem as will produce stasis, coagulation-necrosis, and gangrene. Com- mencing by frictions with snow, then immersion of the part in water, all treatment being conducted in a cold apartment, the temperature of the ap])lications and of the room must be gradually raised nntil the somatic and local temperatures have nearly attained the normal, when applica- tions which tend to stimulate to action the paretic local vasomotor apparatus are indicated, such as diluted alcohol or diluted spirits of camphor. Elevation of the parts, which should be swathed in raw cot- ton, M'ill tend to relieve the venous stasis by favoring the return of blood. Warm stimulating drinks, as hot coffee, aromatic spirits of ammo- nia, or whiskey diluted with hot water, are now indicated. Should inflammation run high, threatening gangrene, antiseptic irrigations may be employed, and in any event asepsis and antisepsis must be maintained throughout. If gangrene results despite all efforts, the constitutional and local treatment advised on pages 358, 359 should be adopted. Gangrene. Sphacelus, gangrene, mortification,' and sloughing are all terms which indicate the death of tissues in greater or smaller masses. This condition is always the result of two factors combined in varying proportions — viz. an insufficient supply of nourishment to the cells, producing a lowering of tissue-cell vitality, and their mechanical destruction. The deprivation of pabulum may be induced in many ways. Thus, the main artery of tlie limb may be occluded suddenly or gradually ; the main veins may become thrombosed, preventing the return of blood, or both conditions may obtain : again, inflammation may lead to such free exudation that the blood-vessels, plasma-channels, and even the cells themselves, may be so compressed as to be unable to maintain their vitality. If to this last condition be added death of some of the cells by mechanical injury, or their lowered vitality brought about by other predisposing conditions, mortification still more readily occurs. In certain injuries of the cerebro- spinal axis or of the peripheral nerves, local gangrene often supervenes, precipitated by pressure, but probably predisposed to by interference with vasomotor equilibrium. Two types of gangrene exist — the moist and the drj' — the presence or absence of fluids in the tissues when gangrene occurs determining to which class the case belongs, the difference being purely a physical one. Dry Gangrene. — This is usually caused by a gradual diminution • Necrosis is a term which should be restricted to death of bone or to g.ingrene of the viscera where the absence of putrtifactive organisms admits of absorption of tlie dead tissues, a scar remaining. GANGREyE. 357 of the arterial supply, the venous blood having free egress. Occasionally dry gangrene follows embolism. Because atheroma leads to such arterial changes as interfere with tlic vascular supply, and as this disease is more common in the old, in whom the feeble heart also predisposes to malnu- trition of the peripheral tissues, dry gangrene is often called " senile gangrene ; " but with the same physical conditions, notably in chronic ergotism, typical gangrene of the feet, hands, nose, and tips of the ears mav occur in the young. Vasomotor spasm, a feeble heart, and ill- nourished tissues all result from living for long periods on spurred rye. Symptoms. — Coldness and numbness of the feet, with cramps in tliem or in the calf-nuisclcs, are fre(pient prodromes. After bruising a toe, trimming a corn too closely, or from the friction of the boot, congestion and inflammation occur. The blush deepens, becomes purplish ; the part is insensitive and cold, but oftentimes severe pain is experienced in the neighboring tissues. The dead parts dry, shrivel, and blacken, emit- ting the odor of decomposition. An inflammatory line of demarcation marks the boundary between the dead and living tissues, shifting upward as the disease progresses until it is arrested, when septic ulceration soon establishes a line of separation. The gangrene may be restricted to one toe or may gradually involve the whole foot and leg, but usually stops just below the knee — /. c. about the bifurcation of the popliteal artery. Little if any fever may attend upon destruction of one or two toes, but where much tissue dies septic fever becomes more or less pronounced. Pain varies from a mere burning sensation to such agony as to require the constant use of morphine. Moist Gangrene. — Sudden obstruction to the main arterial current, as by embolism or ligature, interference with the return of the venous blood, and cutting otf of the ultimate blood-supply to the tissues by the pressure of inflammatory exudates are the usual causes. Because moist gangrene so often follows traumatism it has been sometimes called "traumatic gangrene." The disease may occur either as a localized traumatic or a spreading traumatic gangrene. Localized Traumatic (Jaiif/rcne. — The injury unquestionably phj^sically devitalizes portions of the tissues, but the chief destruction results from the pniducts of the scjitic inflannnati(jn so compressing the vascular sup- ply (capillary and arterial) to the tissue-cells that they die : doubtless fer- ments and ptomaines also play a part. The damaged tissues perish with some of the surrounding parts from the inflammation, but the process docs not extend indefinitely. Symptoms. — Tiie liurning pain often preceding mortification entirely ceases ; the skin is cold, pale, insensitive, then becomes mottled green or red, and finally livid. Blebs form containing brownish serum. Wlien the blebs are ruptured they leave a dermis resembling moist smoked beef; moreover, before rujiture they can be slipped around over the dead derm, because the devitalized epithelium reatlily separates, thus being distinguishable from the lilisters forming after inflannnation. The sur- faces of the wound become puljiy, yellowish or grayish, and exude a profuse oifensive discharge, and the dead part undergoes putrefactive changes. The dead tissues contrast sharply M'ith the living, intensely reddened tissues, separation occurring from septic ulcerative inflammation unless the patient dies from sapriemia, which is unusual, and recovery 358 SYMPTOMS A\D TREATMENT OF GANGRENE. ensues. Hemorrhage is not common, bw^ause softening of" tiie tln-onihi wliieli form in the vessels by the action of the products of germ-growtii rarely occurs. The prognosis is better wheu the original injury has ])ro- duced either an extensive wound or many wounds of tiie soft parts, which allow vent for the poison-laden discharges. Spi'eadiiir/ Trauiiiaiic Gangfene. — This results from specific infection of tissues whose vitality has been lowered by severe traumatism, espe- cially if the main vessels are destroyed. Where the vessels are intact the rapidly-spreading infective inflannnatiou destroys the tissues, partly by strangulation of their minute lilood-supply, lint chiefly by the effects of the ptomaines, peptonizing ferments, etc. which are generated and confined under pressure. Hence severe crushes with but trivial division of the soft 2>arts are most dangerous. The infection is often a mixed one, but sometimes one only of the pathogenic germs is present. The cellular tissue is that which is chiefly attacked ; hence the disease is more extensive than external appearances would indicate. Symptoms. — Tiie linil) becomes tense and brawny, the skin of a dull reddish brown, variegated with streaks and spots of green or black. Emphysematous crackling can often be felt, which extends somewhat above the point of apparent skin-involvement, and usually higher upon the inner side of the limb. The gangrene extends witli lightning speed, sometimes in less than forty-eight hours involving a wliolc lower limb with half of the abdomen and trunk. So soon as the local condition is fairly started, owing to the absorption of enormous doses of ptomaines and toxines by the lymphatics of the cellular tissue, which are un- blocked by any exudate upon the proximal side, marked constitutional symptoms of saprremia develop, which soon terminates fatally unless art intervenes. VoriKfifidional St/mptoms. — If the process be extensive or involves an important organ, the heart acts feebly, the pulse is quick, compressible, and small, the tongue dry, brown, and covered with sordes which extends around the teeth and upon the lips ; in fact, a typhoid state exists. Treatment. — If possible, remove the determining cause, which can often be done by strict antisejjsis after injuries, especially in the aged, and, in threatened gangrene of a crushed limb, by incisions which will give exit to septic discharges and I'elieve strangulation of tissue. If obstruction of the main vessel has occurred, favor the establishment of the collateral circulation b}' moderate elevation of the limb, warmth, and cardiac stim- ulants. Thorough disinfection of gangrenous parts, followed by dry antiseptic dressing, such as iodoform or boric acid combined with ]30w- dered charcoal, often jn-cvents septic infection. Inflammatory products must be evacuated by incisions carried, when possible, through the dead tissues. When the process tends to self-limitation in senile gangrene, delay is advisable, removing the dead tissues from time to time ; second- ary amputation may be done later if the stump does not heal. When senile gangrene spreads, although an amputation lielow the knee may succeed, removal of the limb at the lower third of the tliigh is better, because the blood-supjily to the Haps comes from the profunda femoris. In embolic gangrene it is best to delay until a line of demarcation forms, otherwise an unnecessary sacrifice of parts may result. For localized gangrene — ;". e. sloughing of the skin and subjacent i? & GANGRENE. 359 tissues — nothing is requisite, except incisions through or partial removal of the dead tissue to evacuate pus, until the line of separation forms. Gangrene caused by crushing of a limb demands immediate amjnitation if the process is rapidly extending. If, however, it is localized, the general condition of the patient must decide what nuist be done — *. c. if septic absorption is producing marked constitutional eftects and the patient can stand the shock, am})utate ; if not, strive to improve the general condition, endeavoring to prevent further absorption of, and to eliminate, all ptomaines which have been already taken up. The only measure otfering any ]irosj>cct of success in spreading traumatic gangrene is prompt amputatimi far above the apparent external limits of the disease. Sometimes, as at the shoulder-joint, flaps may be successfully fashioned out of infiltrated, oedematous tissue. The flaps must be long, and if there be doubt if all infected tissue has been removed, primary suturing had better be avoided, antiseptic irrigation employed, and secondary suturing resorted to later. Alcohol and cardiac stinuilants, with quinine and opium to secure sleep, must be given. Large quantities of easily-assimilable food should be provided. Care must be taken to see that the kidneys and bowels eliminate properly. Hospital Gaxgrexe is an infective microbie disease which usually attacks an open wound, but has followed subcutaneous injuries. The disease is hardly known now, owing to the avoidance of overcrowding of patients and to antisepsis, the vii'us probably being a special micrococcus which may reacli the wound through the medium of the air, the nurse's or surgeon's hands, instruments— above all, sponges. The microbes, in both masses and chains, are jjresent in the slough and the surrounding tissues, but not in the blood. Three distinct forms have been described — viz. the dipiitheritic, tiie ulcerative, and the Jjulpv. The first variety — thought by some to be a mild form of hospital gangrene, but by otiiers to result from a diiferent and specific micrococcus — produces a coagula- tion-necrosis of the graiuilations, the wound-surface being covered Avith a yellowish or grayish-white, tenacious pseudo-membrane ; the discharge is at first scanty, but later becomes more almndant and watery. This form is but slightly contagious, and only j)r(jduces systemic results by jitomaVne absorption. When the sloughs sc])ai'ate a deep excavation is left, but during the whole process there is little inflammation in the sur- rounding tissues. The ulcerating vai'iety is characterized by a rapidly- spreading, rather superficial ulcer, covered by unhealthy grayish gran- idations, with inflamed, reddened, sharji-cut edges : the discharge is free and excessively offensive. The pulpy form is often epidemic, and when attacking an open wound causes gr(>at swelling of the granulations. Pultaceous, ash-gray, adherent sloughs soon form, extending rapidly in depth and extent,' with a profuse, thin, greenish or sanious offensive discharge. The surrounding tissues are dusky-red, swollen, (edematous, the margins of the ulcerated surface being sharp-ent, elevated, and excessively tender. The main vessels may l)ecome eroded, producing hemorrhage, and even large joints may be laid open. Profound consti- tutional symptoms, assuming a tyj)hiii(l character, due to ptomaine absorption, set in early, sometimes producing death in a few hours. Treatment. — Prompt isolation must be effected. Where numbers of patients, as soldiers, are attacked, tents or huts are preferable, even 360 SYMPTOMS AND TREATMENT OF GANGRENE. ill cold weather, to crowded wards. Tlie patient's strenijtli must he sus- tained hy food, stimulants, quinine, strychnia, and (lii;-italis, and opium given to ohtain sleep. The enuuictorics — hy which the ahsorhed jitoiuainos may he eliminated — should be stimulated. Locally, in the diphtheritic form, efficient disinfection, followed by the free use of iodoform, will often suffice, but in the more severe varieties the patient must be anies- thetizcd, all sloughs cleared away, and what still adheres of them, with the surrounding infected area, nuist l)e thoroughly destroyed with Ijromiiie, nitric acid, or the thermo-eautcry. After this, free dusting with ioiloform and the careful use of wet antiseptic dressings will bring about recovery if the systemic infection be not too great, provided all infected tissue has been destroyed; if recrudescence of the local symptoms occurs, a repetition of the caustic treatment is indicated. Bed-80RES, or Decubitus. — Tliis is a moist gangrene, produced by pressure mechanically interfering with the access of blood to the tissues of patients lying for a considerable time in one position. The weak heart and tissues of such individuals predispose to gangrene, bed-sores occurring most frequently during acute or chronic exhausting ailments or in ])arts deprived of nerve-influence, as after fracture of the spine. When the slough has separated the ulceration sometimes extends widely and deeply, and may end in death by j)y:emia, hectic, or exhausting (hs- charges. The most common sites for bed-sores are over the coccyx and sacrum, the great trochanters, the shoulder-blades, malleoli, and back of the heels. Treatment. — Bed-sores can usually be prevented by frequent bathing of parts subjected to pressure, covering the same with soap plaster spread upon wash-leather, removing pressure by padded or air rings, pillows, etc., and frequent change of position. Once formed, removal of pres- sure as far as possible, disinfection, and dry dressings must be tried. After separation of the sloughs the resultant ulcer must be treated as recommended elsewhere. White Gangrene. — The etiology is obscure, and it is said to be due to some general, not local, cause. It is a recurrent disease, and appears during early adult life in those who are feeble and ill-fed. It is probably due to some peculiar localized vasomotor condition producing a nearly perfect anaemia of the dead parts. Symptoms. — Although any part may be the seat of the disease, the extremities are the i)arts usually attacked, and by preference the lower ones. Pain, following the course of the main nerves if a limb is attacked, jjrecedes each attack, lasting for weeks or even months. Irregular menstruation and various nervous symptoms are observed in females. Locally, a circumscribed spot on the limb, usually circular in outline, or a toe, becomes dull A\'hite ; the skin soon dries and shrivels ; b}' a septic inflammation a red line of separation forms, and the slough comes away, leaving a granulating surface. When only the skin is involved, the disease is comparatively trivial, but when all the soft parts down to the bones are destroyed, it is a serious, and sometimes a fatal, atfection. Treatment. — This does not differ from what is recommended for the other forms, but the constant current is suggested, so as to modify the vasomotor condition of the parts. GANGRENE. 361 Glvcosttria. — Tlic relation borne by glycosnria to ganp;rene may be briefly stated thus : While patients whose urine contains sugar are more liable to sutler from gangrene whieii pursues a rapid course, because the tissues of diabetics are weak and prohalily attbrd favorable pabulum for the growth of germs, the mere presence of sugar does not cause the disease. Again, diabetics very frequently have arterio-sclerosis ' and a variety of peripheral neuritis closely resembling that produced by alcohol. The neuritis" attacks liy preference the nerves of the lower extremities, giving rise to perforating idcer, the knee-jerks being tem- porarily or permanently abolished, but the Argyll -Robertson pupil has not been observed. Gangrene occurs in patients with sugar in the urine wlio belong to three main classes, as pointed out by Godlee — viz. (!) simple dialectics ; (2) gouty persons with sugar in the urine ; and (3) diabetics who are also gontv. The determining causes are inflammation (perhaps very slight), coinciding with either arterio-sdcrosis or neuritis, the first variety usually being painful and spreading rapidly, the neurotic form being slower and comparatively painless. Treatment. — All operative interference has been opposed until re- cently, but numerous observers have shown that when painful and rap- idly spreading — /. c. when arterio-sdcrosis is present with plugging of the vessels — a prompt knee or thigh amputation often saves life, and the sugar sinks to a minimum after healing, when during the gangrenous inflammation neither medicine nor diet availed. The chief' causes of failure are a too low amputation through the area whose main vessels are thrombosed, including infected tissues in the flajis, after infection, and late operation, especially in those in whom the urine has become albu- minous. In the neurotic form, where one or two toes are involved, spontaneous separation and recovery sometimes occur, and in this variety, and in that starting from a perforating ulcer, delay with I'cmoval of the dead parts and antisepsis is permissible — nay, often advisable. Dietetic and medicinal treatment after operation is requisite, often con- verting the more acute into the chronic form of diabetes, and in the chronic form, where of course tlie prognosis is better, life may be pro- longed for many years.^ Symmetricai> Gangrene, or Raynaud's Disease, is a rare affection, believed to arise from a condition of the vasomotor apparatus in which it reacts abnormally to cold or other irritants, producing by reflex action persistent vaso-constrictor spasm. Although attacking any peripheral parts exposed to cold, the tip of the nose, an ear, the cheeks, and tlie tips of the fingers and toes are the parts usually involved. Children or young adults are those usually attacked. Symptoms. — Usually a varying period, marked by intermitting attacks of pallor, coldness, ard numbness of the parts, is noted — i. e. local sj/ncopc ; in many cases tlie next symptom is a bluish, congested appearance presented l)y the parts (local atlood-supply of the cerebral cortex has been observed : this is explainable by the reflex effects produced upon the vasomotor sys- tem or by thrombosis produced by disintegrated red corpuscles. Treatment. — First relieve pain and treat the shock. "Where mere erythema exists, unless much surface is involved, only local treatment is requisite, dressings such as will exclude the air or will neutralize the acidity of the secretions being indicated. Oil, fresh lard, or cosmoline, previously sterilized by heating, best fulfil the first indication, while a paste of bicarbonate of soda made with sterilized water will meet the second. In burns of the second and third degree, if much surface is damaged, two courses are open — viz. a preliminary thorough disinfec- tion with a weak mercuric-bichloride solution, followed by a moist dressing impregnated with some non-poisonous germicide, as boro- salicylic solution or hydronaphthol, the whole covered with oiled silk ; or, after the preliminary cleansing, all injured parts must be carefully covered with protective, outside which a wet sublimate or other poison- ous germicide may be safely applied, with abundance of cotton externally. When such a dressing requires changing — which should only be done at as long intervals as possible — any cleansing needed can be effected by BURNS AND SCALDS. 3G5 sterilized watei' or some non-poisonous, non-irritating antiseptic solntion. Irritating and readily-absorbed poisonous substances, lilie carbolic acid and corrosive sublimate, should be esciiewed if possible, and never kept in contact with large surfaces, lest constitutional effects result. The constant warm sterilized-water bath, when feasible, or antiseptic irriga- tion, is useful where much sloughing results, but is only apjjlicablc to extremities, and is not easy to manage effectively : moreover, absorption of poisonous substances readily occurs during irrigation or baths, and must be carefully guarded against. After separation of the sloughs healing of the granulating surface must be promoted, upon general principles. The granulations are apt to become either congested and fungous, bleeding readily, or (edematous. For the former condition soothing and slightly astringent ajiplications, such as sterilized zinc-oxide ointment, nnist be used ; for the latter moist dressings should be, as a rule, avoided : astringent and stimulating dress- ings, as resin cerate, a])])lications of solution of zinc sulphate (grs. j-x to f SJ) or of copper sulphate in similar pi'oportions with each dressing, with the occasional use of solid nitrate of silver to tlie margins, are about the best. Chloral hydrate, grs. x to f gj aquiB, applied by means of lint cov- ered with oiled silk, will often act admirably, but is apt to produce a con- gested, fungous state (if the granulati<:)ns if employed too long. It must be remembered that unless the whole thickness of the skin be destroyed the epithelium around the liair- and sebaceous follicles will proliferate, thus accounting for the epidermic islets appearing in the midst of tlie granulating surfaces left after burns. These centres of cicatrizati(jn must be carefully conserved. Skin-grafting, preferably by Tliiersch's method, and plastic operations, are often requisite to secure healing. Tiie deformities resulting from cicatricial contraction may to a certain extent be ob\'iated by positi(jn, s[)lints, etc. employed during the healing process, but when much skin and fascia have been destroyed some plastic procedure will become requisite. Such operations are in- advisable until all tendency to contraction has ceased — /. <;. usually in from six to nine months — unless the lower jaw is becoming curved down- Avard by the traction in the very young, when periiaps some operative interference may bo warranted earlier. SuxBtJRX. — While usually only annoying, causuig much burning pain, wiien a great extent of surface, as two-tiiirds, is involved, death has resulted from the severe dermatitis and subsequent gangrene. Exten- sive vesication is conunon. Erysipelas is closely simulated at times when the face and eyelids are involved, but there is no febrile disturb- ance.' Treatment. — It is that of a burn of the first degree. Brush Burn. — This variety of contused wound is caused by rapid friction, as that produced by the revoK'ing leather belts of machinery or tile dragging of a i)atient oxev the roadbed by a train of cars or by a run- away team. This painful condition may vary from a superficial abrasion to complete destruction of the skin and undcrl}ing tissues. It is rarely extensive enougli to be dangerous. ' See vol ii. p. 224, Intrnxit. Enci/. of Suir/. Longstreth here reports one case where tlie muscles and synovial teudinous sheaths of the forearm and wrist became secondarily involved. 3C() SYMPTOMS AND TREATMENT OF WOUNDS. Treatment. — This is identical with that of a contused wound which sloughs. IjK;htnixg-.sti!OKE. — Wliile it is true that the passage of a power- ful current of aerial electricity througji the human frame usually results in death, tliis is not invariable. \\ liat is commonly called "struck by lightning " means that air-indueed electrical shock occurs in the individ- ual when some contiguous object, as a tree or another person, receives the direct (>leetrical discharge. Symptoms. — In non-fatal cases the phenomena of shock are jiro- nounced, luicousciousness or coma lasting from a few hours to daj'S. Im})airment of one or more of the special senses is common, v.'ith paresis or paralysis of both upper and lower extremities. Localized aufesthesia is quite usual. These pareses or paralyses are usually transitory, except perhaps that of vision. Locally, burns of varying depths are not uncommon, while simple or compound and conuninuted fractures, and even partial or comj)lete avulsions of extremities, have been reported. A peculiar arborescent series of tracks, characterized bj- slightly cedema- tous, raised, bright-red lines, often diverge from the point where the current entered. Where death is delayed it results from shock, cerebral efiPusions — hemorrhagic or otherwise — or hemorrhages into some of the great cavities, with perha])s rupture of some of the contained organs, or the severe fractures already mentioned. Treatment. — This must be conducted upon the general principles governing the treatment of shock, burns, or paralysis of any nerve or nerves. Wounds. A wound is a solution of continuity suddenly effected by anything^ which cuts or tears. When this is effected without division of the skin, the term "subcutaneous" is employed, the injury giving rise to little or no constitutional symptoms, and healing taking place by simple adhesive inflammation. Wounds are usually classed, according to their causation, as incised, when resulting from a sharp-edged object ; contused, when produced by more diffused force, which divides the tissues, leaving the woiuid- edges bruised, as i'rom the blow of a bludgeon ; laeei-ated, when irregu- larly torn, as by the bite of a wild beast, entanglement in machinery, etc. ; punctured, when the depth much exceeds the superficial area, as bayonet, knife, and sword \vounds. Incased Wounds. — Because the injury cleanly divides the tissues, not dragging on or tearing contiguous sensitive parts, the pain is apt to be less in this variety of wound. The bleeding varies, but is much freer than in lacerated or contused wounds. Wounds of the face bleed very freely even if no considerable vessel be divided, the same being true of the seal]); but in this latter situation the hemorrhage occurs because the density of the scalp-structui'es interferes with the contrac- tion and retraction of the vessels. Retraction of the edges of incised wounds always occurs, dependent upon the position and subjacent structures. This point it is important to remember, because if incisions are properly planned few sutures will be requisite, and these will be efficient ; thus skin and fascial wounds made WOUNDS. 367 transverselv to the course of underlying muscular fitjrcs will gape widely, but if made parallel to the muscle their edges will either remain in contact or require but little artificial aid in maintaining this position. " Langer's investigations into the direction in which the skin splits show that the tension of the skin varies greatly in two different directions : two incisions vertical to each other exliibit a varying retraction of the wound-margins ; Avhile one gapes widely, the edges of the other remain in contact even without artificial means." . . . . " Fortunately, the course of the nerves and vessels largely coincides with the direction in which the skin shows the greater tension." ' Skin and muscle gape most widely when divided, the one across the line of cleavage, the otlicr at right angles to its fibres. Gaping is greater when there is much inHainmatory tension of the sub- jacent parts. Union of Incised Wounds. — The hemorrhage having been arrested, the wound, accurately closeil, drained if necessary, kept aseptic and at rest, unites without supjniration by simple adhesive inflammation. If the epithelial covering be thin, the edges may occasionally present for the first twenty-four to seventy-two hours a faint blush, Init this is often absent. They are ])erhaps slightly swelled, are hotter and tender on pressure, but are devoicl of pain : sometimes all these symptoms are absent. Even at the end of three days, although the union seems firm, the wound-edges can be pulled apart — the union is mechanical, not vital, resulting from the gluing together of parts Ijy cellular exudate and fibrin. If undis- turbed, in a few more days a narrow reddened -streak indicates the position of the former cut, the color fading in time into white until the scar almost disappears. This process is primary union, or " union by first intention," and an attempt to secure it should always be made. If perfect coaptation, drainage, and asepticism be impossible, the faintl}'-reddened margins soon show a decided inflammatory blush ; the edges become swollen and tense, throbbing pain is complained of, union fails to occur, and pus forms. A chill or rigor may occur, and headache, fever, anorexia, coated tongue, constipation, scanty high- colored urine, with nervous symptoms varying from mere restlessness to slight delirium, indicate that septic traumatic fever has supervened. If, now, effective drainage and antisepsis be instituted, all the symji- toms will decline: granulations form; the wound-margins ai'c no longer elevated, but rather depressed ; the masses of granulations level the inequalities of the depths of the wound ; the deeper layers become convertetl into young connective tissue, which contracts, thus lessening the superficial area of the \\ound ; epithelial cells extend inwai'd from the margins until cicatrization is completed, first a red, and finally a white, scar remaining. This process constitutes healing by granulations, or " healing by second intention." In brief, the process of repair l>y primary union is as follows : A small quantity of exudate, containing fibrin-forming constituents, coagu- lates, temporarily gluing together all surfaces which arc in apposition, the excess of exudate, if any, being drained off. Leucocytes collect along the line of the wound, gradually increasing in numbers until many of the original tissue-elements disappear, leaving only a mass of so-called " indifferent cells " lying in the meshes of a granular or fibril- ' Kocher's Operative Surf/ery, 1894, p. 29. 368 SYMPTOMS AND TREATMENT OF WOUNDS. lated reticular intercellular substance. At first these cells receive nutri- ment indirectly from the lilood-vessels through the plasma-eanais de- scribetl by Thiersch, whicli are themselves in direct connnunication with the blood-vessels. While granulation tissue contains leucocytes, the weight of evidence favors the view that the cells of granulation tissue result from the iiroliferation of the fixed connective-tissue cells and possibly those of the parencliyma of organs, the leucocytes serving as food for these cells. Soon capillary loops develop from pre-existing blood-vessels, penetrate the masses of cells, and pass across from one side of the wound to the other. Pari passu with this spindle-eells develop from the round-cells. Most of these spindle cells, in turn, disappear as the new fibrous tissue forms, either by conversion into this or by granular degeneration and absorj)tion. On the surface of the wound new epithelial cells are formed from the deeper layers of the rete mucosum, sometimes under a scab of dried blood and exudation-material, beneath which the young cells remain undisturbed until fully developed, when this portion of the process is essentially what has been termed " healing under a scab " or " by scabbing." If too much exudate, serous or primarily more solid, is allo^ved to accumulate iu a wound, the mechanical bond effected by the fibrin is broken down, thus delaying union ; if excessive congestion occur, much more if inflammation results from any cause, this mechanical disturbance from excess of exudate is probable. It also favors infec- tion and interferes witli the processes of repair. The same processes occur in wounds with loss of substance or where primary coaptation has been neglected. In lacerated and contused wounds the damaged tissues must, indeed, be first removed, which is effected — whether tliev be hard, as bone, or soft, as cellular tissue — by the accumulation, at the junction of the dead and living tissues, first of numerous leu- cocytes, then of cells gradually forming granulation tissue, substitut- ing the tissues at such points. Finally, the intercellular cement or reticulum of the boundary layer of cells dissolves, loosening the slough, which floats away in the liquid exudate, leaving a layer of healthy granulations beneath. When situated upon a free sui-face healthy granulations present a level, slightly granular surface, whicli does not project above the margins of the wound ; they are of a pink color, a small amount of creamy pus being secreted if infection has occurred, or an opaque serous or occasionally viscid fluid in aseptic cases. The mar- gins are smooth, shelving, uninflamed, and an advancing border of bluish-white new epithelium is present. Healing by Second Intention. — This is the normal method where loss of substance has occurred either from accident, operation, or where gaping results from failure of primary union. While it is usually stated that the wound " fills up," the fact is that, although this occurs to a lim- ited extent, the organization of the deeper portions of the gramdations causes a marked diminution in area of the surface and a drawing down of the margins, leaving a much smaller surface to be covered in by epi- dermis than is usually supposed. Upon this organization into scar- tissue of the granulations, and tiicir uninterrupted subsequent contrac- tion, depends the healing of many ulcers. Healing by granulation is then the rule in contused and lacerated wounds, and in incised wounds WOUNDS. 369 whose surfaces cannot be coaptated or where primary union lias failed. AVheu two surfaces covered by iieahhy granuhxtions are held in contact, fusion often occurs ; loops of blood-vessels pass from one side to the other, fibre-cells stretch across, and the wound promptly closes by seo- ondari/ (tdhcsion, or " by third intention." This process is purposely utilized in certain cases, " secondary suturing " being employed for coap- tation. Treatment of Incised Wounds. — First arrest the hemorrhage, then cleanse the jtarts In- a gentle stream of sterilized or antiseptic water. Ne\er distend a wound-cavity. Remove foreign bodies with forceps ; do not rub the surfaces with a sponge. If the dry method of operating be jjreferred, of course no water is employed, the wound being cleansed with pledgets of sterilized gauze, etc. Where the wound is irregular and deep, especially in not very vascular parts, one of two courses must be pursued — viz. either all spaces where blood and serum can collect must be effaced h\ buried sutures, or some means must be provided for the free escape of blood first, and scrum later ; which latter is exjjressed from the clots or exudes from the irritated surfaces : the coagulable mate- rial probably contains nucleins enough to destroy germs, but the serum does not. Drainage is not usually necessary for more than twenty-four to forty- eight hours. If, however, infection has occurred and disinfection cannot be assure'ilant form, with delusions, the patient seeing snakes, insects of all kinds, animals, or devils, constantly conversing with himself, and, while capable of answering rationally on other subjects than his delusions, when left to himself promptly becoming again incoherent. At times maniacal outbreaks occur, with suicidal and nunxlerous impulses, usually resulting from injury received during alcoholic excesses: this is true mania d potu. Such apparently suicidal acts as jumping from windows are often only eiforts to get away from pursuing de\-ils or imaginary per- sons threatening bodily injury. Unless restrained, the patient will not remain in bed, making efforts to get up despite a broken limb. The skin is moist, tlie hands siiaking ; the tongue when protruded is trenudous, coated witli creamy fur at first, later, in bad cases, dry, brown, and cov- ered with sordes ; the pulse is full, soft, and (juick ; and the temperature is about normal. The face and whole manner indicate suspicion and fear. Constipation is the rule ; comi)lete anorexia is present, although fluids may be greedily swallowed, and sleep is impossible. Prognosis. — If the patient is young and has sound kidneys, recovery is the rule, Init when the reverse olitains death by exhaustion is not un- conuuon. Treatment. — In drunkards attention to the bowels, anodynes to pro- duce sleep, proper food, and lessening (but not stopping) stimulants will often ward off an attack, which the experienced surgeon anticipates in those tremulous, sleepless individuals so often brought into our large hos]>itals. Traumatisms inflicted upon individuals who are only mod- crate drinkers often suffice to bring on delii-ium tremens, wliich other- wise would never have occurred. Sudden withdrawal of the accus- tomed stimulant sometimes ])recipitates an attack. During an attack two indications are imperative — viz. to induce sleep, thus jircvcnting fatal exiiaustion of the nerve-eeutres, and to maintain their nutrition l>v proper food. A laxative or an enema should be given, and, as liquids are usually acce})table, tlie patient can be induced to take beef-tea or meat-broths, which, in the case especially of old drunkards, will be rendered more palatable by considerable quantities of cayenne pe])per, this condiment acting as a stimulant of both digestion and the cirt'ulatiou. Occasionally forced feeding Mith the stomach-tube may be requisite. With the older patients, where the kidneys are apt to be dam- aged, opium is not advisal)Ie, but in young, sound patients the hypodermic use of morphia may prove useful. Chloral, in from 15- to 20-gr. dt)ses, combined with potassium bromide, every two hours until sleej) is induced, and carefully watched, is usually both safer and more prompt in action. AVhile it may be safe to at once withdraw all stiuudauts from the young anil robust, such practice is not wise in the old or in feeble patients. That stimulant which tlie individual is accustomed to should be given, but in smaller quantities than usual, and it should be gradually with- drawn. After securing prolonged sleep, tonics, good food, and gradual stoppage of stimulants will usually effect a cure. The judicious use of strychnia hypodermically will aid this, while supporting the heart aud nervous system. While it may be pt)ssible to secure to the bed a jiatient who has a fractured lind), it is exceedingly difficult to avoid further injury to this, a simple fracture often l)eing converted into a compoimd one.

If now the injury be rendered compound, no special harm will result. Securing patients to the bed by approi)riate ajjparatus will often be requisite, as they will get \\\) and walk even upon a broken liml). Traumatic Hysteria. This term is applied to tiie nervous symptoms often observed after severe physical shock, especially when combined with mental shock.' As such comliiuations are more fretjuent after railway accidents, tlic term "concussion of the sjiine " has been until recently often applied to the condition, or " railway spine," but similar cases result from other forms of accident. Physical injuries to the nervous system, or the re- sults of such, as inflammatory or degenerative changes ; the arousing of latent pathological conditions, with all distant injuries of peripheral nerves giving rise to reflex effects ; or an ascending neuritis causing central trouble, — must not be confounded with traumatic hysteria. Neurasthenia, arising as it does from " a general defect in tiie mitri- tion and action of the nervous system," must not be confoimded ^vith traumatic h3'steria. According to Thorburn, the following complexus of symptoms is, with slight variations, constant after many injuries, especially railway ones ; it follows tliose of shock, showing exhaustion of the nervous system, lint usually soon disappears under " time " treatment, and must be carefully distinguished from iiysteria. Symptoms of Neurasthenia. — Tiiese are "general debility, confusion of thought, loss of memory, mental irrital)ility, disturbed sleep, dreaming, headache (usually posterior), interference with visual accommodation, photophol)ia, palpitation, frequency of pulse, dyspeptic troubles (furred tongue, foul breath, constipation, and nausea or epigastric pain), sweat- ing, a concentrated condition of tlie urine, etc."" While neurasthenia is often associated with hysteria, and is nmch more frequent than the latter, it is probably a distinct condition, hysteria being due to " sug- gestion " or " auto-suggestion," and neurasthenia to mere exhaustion. Age predisposes to traumatic hysteria and neurasthenia, these affec- tions belonging chiefly to middle life. Hysteria is more likel}' to occur in females if injured, but as nu)re males are exposed to the causes of traumatic hysteria, more men actually suffer from it. A neurotic tempera- ment and chronic alcoholism both favor traumatic hysteria, as they do the ordinary form, but do not have so much influence as in the latter variety, especially the neurotic tenqierament. The exciting cause is 'Oppenheim calls these troubles traumatic neuropsychoses. Thorburn classifies functional neuroses following traumatisms as follows : 1. Acute effects : («) general nervous depression — "shock" or "collapse;" (b) a more localized and defined disturbance of cerebral (cortical) origin — "acute hysteria" or " hysterics." 2. Chronic after-effects: (o) general nervous depression — "neurasthenia;" (h) a more localized and defined disturb- ance of cerebral (cortical) origin — " chronic hysteria." Thorburn's definition of traumatic hysteria is: "A functional affection of the nervous system resulting from an injuiy, due probably to a change localized in some portion of the cerebral cortex, and manifested by correspondinglv well-defined and localized symptoms." — A Contribution to the Surgery of the Spinal Cord, Wm. Thorburn, B.S., B.Sc, M.D. (Lend.), p. 186 et seq. = Thorburn: Op. cit., p. 185. TRAUMATIC HYSTERIA. 377 some accident, but mental impressions Iiave a large share in tlie cansa- tion of" traumatic hysteria ; thus Thorburn insists that a previous period of terror, horrible surroundings, and the instantaneous occurrence of the accident have more effect tluui the physical injury. Direct injury to a nerve-trunk is a "potent cause" of hysteria. While the severity of the traumatism itself has no special tletermining influence, the locality has, "complete hemiantesthesia or double monoplegia" on the same side as that of the lesion often occurring after head-injuries. Surgical operations are traumatisms, and oft«n give rise to various functional neuroses. Symptoms. — While the ordinary screaming, laughter, crying, or possibly convulsions so often observed after accidents are evanescent and of no moment, leaving at most some temjxn'ary ner\'ous exhaustion, there are certain peculiarities observable at times, especially after railroad accidents. Thus patients will maintain that they have been unconscious for a longer or shorter period, yet investigation shows by the absence of vomiting, relaxation of the sphincters, etc. that this condition could not have been due to cerebral concussion. Such patients walk, travel long dis- tances, do many voluntary acts almost automatically, sometimes regaining their consciousness, astliey describe it, after a considerable interval of time and distance of space. They present a peculiar dazed appearance — in fact, resemble in many Avays those in the somnambulistic state. Exaggerated or purely imaginary statements are made pertaining to the accident. These illusions are ])robably the results of "auto-suggestion" during a state closely approximating that of the "minor degrees of hvpnotism."' These preceding conditions have been called acute hysteria, while those following belong to ciironic hysteria. It will be impossible to more than mention the chief manifestations of chronic hysteria. According to Thorburn, thev may be — (1) psychi- cal, including e[)ileptiform attacks and hysterical insanity ; (2) motor, including jiaralysis and contractures of the limbs and special effects upon the larynx and the bladder ; (3) sensory symptoms — anesthesia, hypersesthesia, and paraisthesise of the general or sensory nerves ; and (4) vasomotor, secretory, and trophic troubles." ^ In most eases symp- toms suggestive of combined neurasthenia are present. Prognosis. — Under f ivorable circumstances, with proper treatment, and when pecuniary comj^ensation is not sought or is promptlv granted, recovery seems frequently to take place. Chronic alcoholism, a distinct neurotic tendency, and the male sex are unfavorable. Marked changes in severity of the symptoms, transference from one side to the other, and temporary disappearance afford grounds for a favorable prognosis. Treatment. — Isolate from friends and relatives, encourage use of any paretic part, discountenance the idea that true paralysis exists, employ massage and faradism, secure prompt settlement of legal ques- tions, give tonics, possibly employ overfeeding, and eschew bromides unless necessitated by " nuich cerebral excitement," when " bromide of ammonium appears preferable to the potash salt."' Hypnotism and "transference" have been' claimed to be efficacious in some cases. ' Thorburn, op. cit, p. 194. ^ Op. cit., p. 194. » Op. cit, pp. 224, 225. 378 SYMPTOMS AND TREATMENT OF HEMOBBHAGE. Hemorrhage. Tliis may be arterial, venous, or eapillary, or may arise from all these sources. Unless arteries of a certain size are divided, bleedinj^ from them and from the veins sjiontancously ceases and (■a])il]arv oozinj^ alone persists. PI(iiiiirrliafi;e is called external when occurrinu- upon a free cutaneous or nuicous surface — internal \vlien the lilood is pnui'cd into sucli cavities as those of the abdomen, [)ericardiuni, pleura, or mediastiiunn. This term is sometimes also applied to hemorrliages into hollow viscera, as the stomach, intestines, or bladder. When blood is poured out in small amount into the cellular tissue ecehyraoses or bruises result, while if the anioiuit be large the term " extravasation " is employed. Traumatic hemorrhages are called " primary " when immediately following tiie injury; "inter- mediary " when they occur between the stage of shock and that marked by suppuration, tJie bleeding I'esulting either from the increased vascular tension of reaction or from coagula occluiling vessels becoming loosened by the premature removal of external ])i-essure ; " secondary" when they occur after supjturation has been established, lieing due to separation of sloughs in\ olving the vessels, or to septic or infective inflannuation of the vessels, leading to their ulceration or rupture or to the solution of the occluding thrombi ; " parenchymatous " when there is a general capillary oozing, due cither to inflammatory dilatation and canalization of the smaller vessels or to throniljosis of the principal vein or veins. Treatment of Heniorrhag-e. — Great losses of blood are dangerous because of the risk of fatal syncope. This must be combated by the retention of a functioning amount of blood in the l)rain, especially iu the respiratory centres. The head and shovdders should be promptly lowered, and this position maintained by elevating the foot of the bed some inches, neither ])illow nor bolster being left beneath the head. The limbs should be raised nearly to a right angle with the body, and thus held. Sometimes, instead of this, Ksmarch or ordinary nuislin bandages can be applied to one or all of the lindjs, or digital or instrumental com- pression of the arteries of the limbs may be substituted. Many lives would be saved if the more essential, if not all, of these measures were instituted \\here the accident has occurred, instead of waiting for removal to a hospital, house, or even to a couch. Next, stimulants by the mouth or rectum must be employed. Tur- pentine rectal euemata act well. Subcutancously, whiskey, ether, atropia, and strychnia will prove beneficial. Artificial heat by hot bottles, and a sinapism over the heart, are useful. Transfusion of a saline solution into the cellular tissue of the pectoral or abdominal region, by means of a hypodermic needle attached to a few feet of small rufjber tubing and a funnel, acts nearly as well as intravenous saline transfusion, and is nuich moi-e readily done : indeed, considerable quantities of sterilized normal salt solution may be injected in a .short time by the rapid use of an ordi- nary hypodermic syringe. As occasion permits, concentrated hot meat- essences, milk, hot coffee, etc. must be given — /. e. liquids which when absorbed will supply the heart with a bullv of fluid sufficient to carry on its functions. As the patient rallies the bandages nuist, one by one, be cautiously removed, the limbs then lowered, but the dejjcndent position of the head must be maintained until all risk of .syncope has passed away. HEMORRHAGE. 379 Later, iron, tonics, and nutritions food are indicated to snpply tlie loss of red cells. Ergot, snlplnn-ic acid, acetate of lead with opium, have all been occasional!}' useful in recurring hemorrhages where the bleeding points cannot be reached — /. c. in enterorrhagia, hseniatemesis, etc. H^EMosTASis. — Tiie local means for temporary hajmostasis are local pressure by lingers, com])resses, tourniquets, bandages, etc. over the wound or on the l)leeding vessel in the wound ; compression of the main vessel above or below the wound by similar measures ; and flexion, especially of the elbow or knee, for wounds of the arteries of the hand or foot. A compress should be placed in front of the elbow or behind the knee, and the limb bent until bleeding ceases, the member being thus maintained by a handkerchief or bandage. Only such styptics are permissibk' as imitate or hasten Nature's efforts, which are, in the case of arteries, lessening of calibre and retraction within their sheaths, with the formation of an external and an internal clot, and in veins their col- lapse and consequent thrombosis. Exposure of wounds to the air after removing all clots, a current of cold water flowing over their surfaces, or ice itself in the wounds or api>lied over tiie dressings by means of an ice-bag or an ice-bladder, are the best means of employing cold. Hot water (125°-130° F., roughly estimated as the greatest heat bear- al)lc for a few moments by the back of the hand), poured over or better applied by pressing a towel wrung out of the water on the wound, acts bet- ter tlian cold and docs not depress tlie vital powers. Alcohol or tincture of iodine pure or variously diluted has been successfully employed by some. Perchloride and subsulphate of iron are poj)ular but unreliable styptics ; moreover, they render asepsis and immediate union impossible. While Monsel's solution is useful for free bleeding from leech-bites, it is better even for such accidents to transfix tiie lips of the minute wounds with fine sewing-uecdles, around each of wiiich a figure-of-8 ligature should be cast. Tannic and gallic acids are less olijectionable than the iron salts, while alum apjjlied by means of cotton saturated in a hot solution has been much vaunted : probably pressure has much to do with its effi- cacy, and an iodoform-gauze tampon would be vastly better. These chemical styptics arc only mentioned to condemn them, excejjt where nothing else is available, as will sometimes occur.' The actual caatcrji, applied at a dull-red heat, is most efficient when primary union is not aimed at or in the peritoneal cavity, in the latter case no eschar being separated. The cautery is often the only resort in such operations as removal of the upper maxilla, where the vessels can- not be isolated. The thermo-cautery is the best form, but any metallic substance, as wire, knitting-needles, etc., can be heated in the fire or gas. Measures for the Permanent Arrest of Hemorrhag-e. — While the cautery for certain cases and the antiseptic tamponade may be employed for this purpose, certain otiier measures are more commonly employed. Torsion. — Only divided vessels can be twisted. Drawing out the whole cut end of the vessel with one pair of catch-forceps, grasp the vessel transversely close to the tissues with a second ]iair. The end of the vessel can then be twisted off, or three or four siiarp turns can be given until the inner and middle coats give way, resistance to further ' In bleeders, but here the thermo-cautery would be better. 380 SYMPTOMS AND TREATMENT OF HEMORRHAGE. torsion tlien suddenly diminishing. Sniallci" vessels which cannot be isolated can be seized with some of the surrounding tissues, all of which should be twisted off. Forcipre.ssure is effected by seizing the vessel or tissues with catt^h- forccps, which can be removed in from a few minutes to forty-eight hours. Ligature. — Properly-prepared silk, kangaroo tendon, and catgut form the best ligatures. If tying a divided vessel, draw its end out by for- ceps or a tenaculum just far enough to place the thread securely. If in dense tissues, the tenaculum sliould be used, and slightly Avithdrawn as the first half of the knot is tightened. A curved needle armed Avith tlie thread can sometimes be more conveniently employed, passing it around the vessels so as to include a little of the surrounding tissues, thus jire- venting the ligature from slipping. When tightening the knot the sur- geon's thumbs or forefingers must jiress somewhat down against the for- ceps or tenaculum, so as not to j)ull the instrument off the vessel or out of its sheath, this latter accident favoring secondary hemorrhage. When the ligatures are to be cut short, whetlier silk or catgut, tlic first half of the knot must be tied only so tight as th(n-oughly to occlude the vessel and maintain its position, damaging the coats as little as possible : when a ligature is to come away, the aim is to divide the inner and middle coats, so that only the external coat remains for the thread to ulcerate through : both modern surgical practice and theory condemn this. A " reef " or " square " knot must be employed to the exclusion of the " granny." An artery wounded in its continuity must be reached through the wound with the least damage to parts, the proximal and distal ends tied, and also any branch opening into the part included between the ligatures.' Mmmres for Recurrent or Secondary Hemorrhaf/e. — Ligature of the bleeding points, when feasible, followed by antiseptic tamponade when a cavity is concerned, is the best. As the bleeding from an artery tied in continuity usually comes from the distal extremity, especially when overlying a bone, a graduated comj)ress and bandage may suffice : this may be tried before religation or amputation. If methodic compression is to be employed, control the artery by pressure above, clear out the clots, apply the compress directly on the bleeding point, and secure it by bandages, which must support the circulation of the whole limb, below and above. Not much pi-essure must ho used, and this should be relaxed after twenty-four to thirty-six hours, to prevent the formation of a slough with renewed Ideeding ; l)ut the compress must be allowed to come away of itself. Where no room remains for the application of a ligature, the wound may be filled with shot or a shot-bag employed as a compress. When all means fail, if an extremity is involved, amputation should be done. ^ Aciipresmre may be used to occlude a vessel, thus: Pass a threaded needle through the tissues beneath a vessel, cast over its jioint a loop of metallic wire, and compress the vessel by securing the wire by a turn or two around the eye-end of the needle; traction of the thread removes the needle, freeing the wire loop. Again, a long, stout steel pin can be passed through the skin and tissues at one side of the vessel and over it, and be made to emerge through the skin on the opposite side. According to the size of the vessel the needle or pin can be removed in from thirty to sixty hours. HAEMOPHILIA. 381 HEMOPHILIA. This disease consists in a tendency to excessive and continnons hemor- rhages, occurring spontaneously or after traumatism. Swelling of the joints is frequently associated with the external hemorrhages. It is congenital, attacks males, and is usually inherited through the mother, who herself escapes. The first manifestations nearly invariably occur before the second year of life, the ])rimary bleeding rarely appearing after puberty. In fact, after this period the tendency to bleed dimin- ishes. The oozing, continuing for hours, days, or even weeks, is always capillary. Epistaxis is the most common form of spontaneous hemor- rhage : slight scratches of the skin, bites of the tongue, leeching, blisters, extraction of teeth, and circumcision are some of the tranmatic causes ; the last three seem especially dangerous. In the sligliter form petechia, €cchvmoses, and hiematomata may occur, either spontaneonsly or from trivial injury. Jcnner reports a hematoma extending from the knee to the trochanter produced by the fall of a rubber ball on the tliigh.^ The petechife, which occur chiefly beneath the skin of the extremities, although sometimes seen on mucous and serous membranes, may be accompanied by swelling and ]>ain in the joints. Either with or with- out these purpuric spots arthritic complications are very connnon. These vary from simple pain to suddenly-develoj^ed redness and intense inflam- mation accompanied by fever, thus closely simulating acute rheumatism. The knee-, elbow-, ankle-, and shoulder-joints are those most usually aifected. Repetition of the attacks commonly results in marked deform- ity and disability. With the exception of ordinary anfemia just after the bleeding the Iilood is normal, wounds healing as in other anemic patients. Histohjgical examination of the vessel-wall has only once afforded confirmation of the statement of Blagden, made in 1817," that the walls are unusually thin, Ividd ^ finding degeneration of the muscular tissue of the middle coat of the arteries and proliferation of the endo- thelium of the arterioles, veins, and capillaries. Hemorrhage into or around the capsules of the joints accounts for much of tlie articular swelling. Inflammation of the synovial fringes and ulceration and de- struction of the articular cartilages have also been reported. Pathology. — Although there must be some peculiar frangibility of the vessels and failure in prompt coagulation of the blood, there are no histological or chemical facts explaining what these abnormalities arc. Diagnosis. — In a lileeder family this is easy. If occurring in a member of a family hitlierto free, and not resulting fi'om slight pro- longed sepsis, reliance must be placed on these points : The spontaneous or tramnatic hemorrhages are multiple, joint complications are frequent, the tendency to bleed persists for years : this would constitute a congen- ital l)lceder, not an hereditary hicmophiliac, and if a male, he would be likely to found a "bleeder family" if he should have offspring. The differential diagnosis from simple hemorrhagic or infective purpura, peliosis rheumatica, etc., mu.st be sought elsewhere. Prognosis. — Few die from the first bleeding. The older the patient the better the chances, especially in girls, who do not seem specially ' Legg : On HminophUia, p. 68. ^ Medko-ckirurg. Trans., vol. xli. ' Loc. cil. 382 DTAGNOSIS AND TREATMENT OF HEMOPHILIA. prone to post-partum liemorrhages, although often menstruating early and profusely. Treatment. — Prophylaxis is imperative ; all operative injuries, ex- traction of teeth, and anything but life-saving (jperations must be inter- dicted. In the presence of hemorrhage cleansing of the \\(>inid, followed by pressure, should be employed. Antipyrine may do good, while repeated injections of cocaine into the gum has checked the oozing after pulling a tooth. Ergot by the stomach, purges of sodium sulphate — except in enterorrhagia — large doses of tincture of chloride of iron, have all seemed to do good. Tonics, iron, cod-liver oil, etc. are inllow)ng trivial as well as severe injuries — the mere prick of an infected lancet, the most indifferent scratch. I have in mind the prick of a wooden toothpick received in the hand in takijig it out of the pocket, necessi- tating subsequently the amputation of the arm to preserve life : medical literature reports similar cases in abundance. It is only necessary that Vol. I.— 25 386 SEPTICEMIA, PYJEMIA, AND POISONED WOUNDS. the bacteria be given access to tlio circulation in order that the disease may be set up ; an evident wound is not necessary. It must not be understood, liowever, tliat all persons thus injured, who are subjected to the same infection, respond ecjually and are su"scci)tible in a like degree to the deleterious effects. It would seem that all blood is not equally good soil for the growth of the germs, or tiiat the tissues of some persons resist their action, so that the general infection does not follow the exposure, and the individual escapes. The infection in septicaemia is shown botli locally and constitutionally, but not uniformly in either way. It depends largely on the character of the wound, but in some degree also upon tlu' virulence of the infection. In cases of open wounds, such as compound fractures or severe lacera- tions of the soft parts, including the skin, with I'ontaniiuatiou of the tis- sues, a class of wound most frequently followed by septicsmia running a typical course, the skin at the seat of injury becomes reddened, swollen, and painful, and the wounded surface becomes covered with a dirty- looking, somewhat thick secretion, which will jiartially wash off, but leaves the tissue underneath of a dull, more or less variegated gray color, -without distinction between different anatomical parts, with a superficial slough and an ajipreciable odor of decomj)osition. This last is an exceedingly important symptom, to be sought for early with great care; and it may be here stated that the great objection to iodoform as a dressing for fresh wounds is that Ijy its strong odor it masks the first positive evidences we have of putrefaction, anil in just so far increases the danger of acquiring the general condition of scpticiemia. At the time that these changes appear in the wound, or very soon afterward, the general system shows evidences of participation, in that the temperature rises — it may be a degree or two, it may l)e more — the pulse and resj)ira- tion are accelerated, the tongue becomes coated, and the })atient complains of a general sense of discomfort ; in other words, an active febrile move- FiG. 10. ment with some, but not severe, evidences of affection of the nervous system, inasmuch as stupor and aj)athy are not so prominent, in this respect differing from the condition of saprtemia or septic intoxication just described. The fever is continuous, but with morning remis- SEPTICEMIA. 387 sions and afternoon exacerbations, gradually on successive days rising higher and higher — the morning remission not reaching that of the previous day — until the acme is reached : this occurs about the fourth ■or fifth day, when, ^^•ith the appearance of suppuration in the wound, the constitutional symptoms abate and the fever sul)sides l)y a similar gradation of declining steps at each day, though more rapidly than it arose, so that, while it Avas from three to six days rising, it falls in from two to four days to a nearly or quite normal temperature. The temperature-chart of a typical case of septicaemia going on to recovery is sliDwn in tlie accompanying diagram (Fig. 10) of a case of com])ound comininuteil fracture of both Ijones of the leg by a railroad injury, occurring in an otherwise healthy man of about twenty-five years of age. The character of the wound, the method or al)sence of treatment em- ployed, the nature of the infective material with which it is contaminated, and the constitutional condition of the individual as to power of resisting the invasion of the infective micro-organisms and the develoj)ment of the toxines, arc, however, factors that modify the course of the disease, both locally and constitutionally, in a great variety of ways. It is of the highest interest to surgeons to know just how to meet the manifold phases. The septic process may spread locally along certain definite anatomical lines ; it may invade all the tissues of a limb or a part, attacking, perhaps ■destroying, every tissue that it meets. The most frequent anatomical site, however, is perhaps the connective tissue, where, owing to the loose arrangement of lymph-spaces, vessel-sheaths, and intermuscular planes, the development of the bacteria is given every facility, and where they do grow almost witliout limit. These are the cases of cellulitis so constantly met with in the hands, less fretpiently in the feet, of tradespeople and those who are exposed to infection from their occupation. Wo find them arising from the most trivial, many times undetected, injuries, usually spreading rapidly, with great pain and swelling. In other instances entrance is gained into the sheaths of the tendons, and tendo-vaginitis of an exceedingly severe character is excited, often going on to suppuration, extending into the palm of the hand, and so on up to the wrist, with the result of the impairment, if not absolute aboli- tion, of function by the destruction of the sheath from sloughing or from the necessary treatment in laying it fi'eely open, the subsequent cicatriza- tion producing adhesions obliterating the sheath, or so attaching it to neighboring ])arts as to prevent the normal play. These cases are intensely j>ainful, owing to the confinement of the swelling inside the fibrous sheatlis, and, while not so deforming as when the connective tissue alone is involved, the integrity of the hand is in greater danger even if am]>utation be avoided. The various distributions of the lymphatic system serve frequently, both in common with the connective tissue and alone, as media for the transmission of the micro-organisms : it may be as a simple lymph- angitis or lymphadenitis, and we may regard septic osteomyelitis as belonging here. These cases are always serious by reason of the very great facility with which they spread, either continuously along the course of the vessels, or more erratically, leaping from one set of glands to another, sometimes quite at a distance, each set serving as a 388 SEPTICEMIA, PYAEMIA, AND POISONED WOUNDS. focu.s for the storing up and further di.strihution of the bacteria. Occa- sionally they suppurate, though they usually do not, but where they do it simulates pyajmia, and tlie diagnosis is then difficult. The more acute course, coming on before supi)uration has appeared in the wound ; the character of the fever, being continuous instead of intermittent; the ab- sence of repeated chills and the torpor of the nervous system, — determine clinically the septic rather than the purulent character of the process, as is confirmed at the autopsy by the absence of abscesses in the parenchy- matous organs. The most virulent form of septic infection, however, appears in the immediate invasion of all the tissues of a part — skin, connective tissue, muscles, lymphatic vessels, and blood-vessels. This invasion is of great gravity, and comes on usually as the residt of extensive injuries to both soft parts and bones. A man of not very robust physique, but otherwise in good health, had his left foot causrht between an elevator-car and the floor above in such a way that most of the sole of the foot, including the tuberosity of the OS ealcis, was nearly crushed off. The ragged skin and enclosed pulpefied mass of bruised tissue were stitched together by an incompetent practitioner, bandaged firmly with cotton roller bandages halfway u]) to the knee, and left practically without further treatment. He was admitted to the New Haven Hospital on the fiiurth day after. There was an extremely offensive odor of putrefaction ; the foot was black and gangrenous; the whole injui'ed portion and the leg to just above the knee swollen, emphy- sematous, and of a peculiar shiny-brown or bronzed color — not reddish. This color had been noticed only on the day previous to admission, but had advanced rapidly after making its first appearance. The pulse was about 105, of good force; the intellect clear; there was considerable^ pain in the leg. The temperature was 100^° F. A free incision was made about halfway to the knee at the spot where the emphysema was most evident ; no pus was found, but the w^ound discharged a thin sani- ous fluid of a more or less yellowish color, mixed with gas, and gas could be pushed out of the wound in the foot from above ; the incision through the skin scarcely bled ; there was no undermining of the skin or opening of the muscle-planes, and it was impossible to get a drainage-tube in Avithout breaking through fresh tissue. An active system of antiseptic irrigation was instituted, but the infection of the tissues continued to advance, and the next morning the discoloration was two inches higher y the temperature a trifle higher, 100j*g°, the pulse 80, the mental conditiou Still good. That the foot would require amputation was without question, and the advancing infection of the leg made it appear as if it would be necessary to take the leg ofl' high up, above the knee, to save life, but the very rapid advancement left it uncertain just where. In the after- noon the discoloration had reached the irregular line shown in the illus- tration (Fig. 11) taken from a photograjjli. At this time the temperature was 101^°, the pulse 115 and more feeble, but there was no stupor or other disturbance of the nervous system other than could be accounted for by the natural anxiety of what the outcome was to be, for it now looked as if the thigh must be ami)utated in the upper third, if not at the hijJ-joint. During the next night there was no advancement of the discoloration, and the temperature had fallen to 101°, in the afternoon SEPTICAEMIA. 389 to 101 j^°, and from this time tliore was a steady subsidence of the un- toward symjttoms, Ijoth locally anil constitutionally, .so that on the ninth day after admission I was able to amj)utate at aliout the middle of the leg. The tissues at the site of the operation still showed evidences of Fio. 11. Bronzed discoloration of skin of leg and tliigh following traumatic gangrene of foot, appearing third day after injury— photograph taken second day thereafter. (From records of New Haveu Hospital.) the diseased condition in that they were infiltrated with serum and did not heal by first intention, but the course of the operation was almost aseptic throughout in that the rise in temperature on the afternoon of the day following the operation was lOOj^g-" F., falling at the next obser- vation to normal. The fortunate result in this case cannot be regarded as the rule, how- ever, in cases of general septic infection with traumatic gangrene, as is illustrated in another case, likewise under my care at the same hospital, where a woman of fifty-eight was subjected to the manipulations of a notorious "bone-setter" for a dislocation of the left shoulder-joint of two weeks' duration. After jirolonged and violent attempts at reduc- tion the arm was finally left with the elbow bound firmly to the side and a pad in the axilla. I saw it first three days afterward : the arm was then black and gangrenous to the elbow, with great swelling and a reddish discoloration of the arm above. The pain was severe, the pulse of the opposite arm rapid and feeble ; the temperature was 102° F. ; the patient was alert in mind, aware of her danger, and anxious to have the arm removed ; the tongue was already dry, and there had been some vomiting. Amputation was deferred to try — first, to improve the heai't's action by stimulants ; second, to try the eifect of anti.septic treatment in reilucing the fever ; third, to see if some line of demarcation would not show itself. The first only of these desiderata came about : the heart did gain strength, but the putrefaction inci'cased, the swelling and redness extended over the shoulder, and began to invade the neck. On the first day after admission the temperature was 103y\j-° F., falling the next morning to 100^*^° F., and rising in the after- noon to l()3/jy° F. ; the tongue continued dry. Incisions were made in the arm for the purpose of washing it out antiseptically. It being evi- 390 SEPTICEMIA, PYAEMIA, AND POISOXED WOUNDS. dent, however, that the sepsis was increasing, and the patient's general condition not improving, tiie arm was am])ntated at about the middle on the second day. At the operation it was found that, instead of a dislo- cation, there was a fracture of the sui-gieal neek (whether this was the original injury or was produced by the violent etforts made to reduce the tlisloeation could not bo told), and that all the tissues at the line of amputation were intiltratcd witii a foul-smelling serum, particularly in the intermuscular planes of connective tissue. The bone was removed at the seat of fracture, and the sinus thus left was mopped out with ])ure carbolic acid, and the wound freely irrigated with mercuric bichloride, 1 : 1000. There was a decided imjn'ovement in her condition immedi- ately and for a few days following the operation ; the temperature fell to iOO° F., but her heart failed ; she was soon after attacked with a septic gastro-enteritis, causing profuse watery discharges, \vhich became choleraic later and involuntary ; her stomach refused to retain anything j she became indifferent to her surroundings, and finally comatose, dying in this condition thirteen days after the injury, eight days after the amputation. This gastro-enteritis is not unusual in severe cases, and is regarded by Gussenbaur as directly due to the action of the products of the septic micro-organisms uixin the intestinal tract. While these two cases bear, in their local action, a marked resemblance to the ffcmgrene foudroyante of Maisonneuve, there is an imjJortant differ- ence in the symptomatology — viz. that the nervous symptoms were by no means so prominent. In the case of the wound of the foot, although the local progress was most rapid, to l)e seen advancing almost from hour to hour, the patient's mind was clear : he ap])reciated the danger of his situa- tion, was desirous to have whatever done that his medical adviser deemed best, and was in no way either apathetic or over-anxious as to his situa- tion. In the other case it was not until just before the arm was ampu- tated, five days after the injury, that the torpidity of the intellect as given by Maisonneuve became a prominent symptom. His cases are described as "being from the l)eginning in a condition of complete apathy ; the wound and its parts affected by the septic infection are almost painless; the patient does not ask for drink, though his dry tongue cleaves to his gums," though in other cases there is great rest- lessness, indeed manifest delirium, with unconsciousness of surround- ings and disposition to toss about in spite of the injuries ; the skin is bathed in perspiration ; the urine and tVeces are passed involuntarily ; the respiration is hurried and superficial, the jjulse weak and intermit- tent ; in other words, there is a condition of extreme collapse, in M'hich the fatal termination appears in from twenty-four to ninety-six hours. In the cases which last long an icteric hue to the skin becomes evident, showing the effect of the jioison on the liver, which on autopsy is usu- ally found swollen and soft. This description is very like that given of septic intoxication (sapraemia), but we are taught that in this the local changes are as nothing. It is therefore evident that the most active fulminating putre- factive local ]irocess may go on for days in an extremity, with no absorp- tion taking place of the products of decomposition to affect the cerebral functions, and finally recover; and, further, that symptoms identical M-ith this acute disease, saprsemia, may come on as a secondary fever SEPTICEMIA. 391 several days aftei" the reception of the injury, an intermediary, compar- atively afebrile, stage being passed through. The effect of the septic infei'ticin, as has been stated, is much the most marked in the systemic disturbances ; the tissue-changes, aside from tiie direct injury, are not very great. They consist in an interference with or a cessation of the proper process of repair, rather than in active destruction. There are cases, however, where the local destruction is excessive, as in tlie gangrenous stomatitis or cancrum oris of children. A characteristic instance of this occurred in my service at the New Haven Hospital.' We have here to deal with the invasion of the tissues by the bacteria to such an extent as to destroy them en masse. It is not a question of a cutting off of the blood-sujjply by an embolic process, as in gangrene of a limb, nor of the destruction of the vitality of the tissues by a violent force, as in railway injuries, nor, again, of the infec- tion of the system from a trivial injury, as in a dissecting wound, but the almost sinudtaneous destruction of all the tissues of the part Ity the apparent invasion of the wiiolc by countless myriads of bacteria of various kinds, staphylococci, streptococci, and micrococci all being found. These cases usually occur in children already reduced in vitality by some debilitating disease, as typhoid fever, but in whom access to the tissues by the micro-organisms is obtained by some slight abrasion — in this the picking at a tooth witli her tinger-nails produced a slight abra- sion which rapidly increased U) an area of iuHannnatiou, followed by Fig. 12, Gangrenous stomatitis following tvplidid fovor about twilfth day after beginning of ulceration.

In spite of energetic treatment the gangrene extended without the slightest check, and in two days the cavities of the nose and mouth were both, exposed and the palate was gone ; in another the lower o'velid had fallen away from the upper by the detachment of its inner eonuuissure ; a large part of both jaws was denuded of periosteum at the bottom of the ulceration, and the bones themselves were already necrotic. The pulse was about 140, the respiration about 40, the temperature varying from 101° to 104° F. On the fourth day after admission the morning temperature was 104j*o° F., the afternooii 9d^^° F. She died on the fifth day after admission, about the fourteenth day from the invasion of the tissues by the bacteria. This extensive destruction by gangrene of all the tissues, the blood-supply not beiaig cut off, is exceptional and only found in similar conditions ; it woidd seem that young tissues, especially when reduced by debilitating illness, afford the most favor- able soil possible for the growth of these micro-organisms ; or, jierhaps it is the same thing to sa}', have no power of resistance to their growth. Multiple peripheral neuritis has been mentioned as the result of sep- ticsemia. One well-marked case occurred under my observation in the person of a professional colleague who wounded himself in the hand at an operation for the opening of a phlegmonous cellulitis. The resulting inflammation was of decided severity, but not extreme, and after a|)parent recovery, having resumed practice, he exjierieneed a gradual loss of power with pain along the nerve-trunks, first in the arm which had been the seat of the injury, but gradually invading both upper and lower extremities. It lasted nearly a month, and gradually disappeared, the recovery being comjjlete.' Gussenbaur's definition of septicaemia, which I have adopted, fixes no definite period of time for the termination of the disease, but the course as described is essentially acute. It is usually a matter of l)ut a few days before death closes the scene or convalescence is established, or, pus forming, the subsequent course is claimed to transfer it into a pyaemia of one form or another. It has seemed to me, however, that if in a certain — and that not infrequent — number of cases the acute nervous symptoms subside and pus in moderate amount apjiears, the character and persistence of the febrile movement justify us in regarding the condition as chronic. It is a continuous fever, with about the diurnal variation that belongs to health, but is from one to two degrees higher. The tempera- ture, instead of running along between 98° and 99° F., runs between 99° and 100° F. or 100° and 101° F., with, occasionally, a rise of a degree or a fraction of a degree more, but seldom falling below ; not presenting the characteristic features of the pyaemic chart, of great diurnal varia- ' Consult Dr. J.

SEPTICEMIA. 393 tions, but keeping the surgeon always anxious lest this sh(iuld develop. This condition will sometimes last for weeks : every hosintal surgeon must recognize the clinical description. I am unaware of any i)ac- teriological observations having been made to establish the patiiological condition behind it, but when we recognize that the occasional sudden accessions of temperature are always to be referred to some circumstance having to do with an increase in the production of the jitomaines of putrefaction, as by a remission of strict antiseptic treatment, intentional or otherwise, and that when this is re-established the temperature returns to its former, but still abnormally elevated, degree, luitil recovery is brought about by the curative processes of nature, the inference seems justitied. It may be urged that I am here giving anotlu'r name to irritative fever. I prefer to give these cases a pathological rather than a purely theoretical classitication. The prognosis of scpticjemia, like that of other acute infectious dis- eases, depends more upon the strength of the individual than upon any- thing else. There are two points, however, to be considered in this relation : the power of resistance of the tissues to the invasion of the micro-organisms, as shown by the rajiidity of extension of the local process, and the amoiuit of systemic disturbance which the individual suifers, as shown in the force and frequency of the heart's action. Single observations of temperature, even though high, are not of much import- ance in a prognostic point of view, but a continuously high fever has^ a bad outlook always. Age is an imjjortant factor, the very young and the aged witlistanding the effects of septic fever and intoxication but poorly; and it goes without saying that any complicati(jn of septic infection occur- ring in ])ersons already reduced by organic affection of an internal organ, be it kidneys, lungs, or heart, is of the gravest prognosis. Other tilings being equal also, the prognosis is greatly influenced by the promptitude and thoroughness of the ti'catment. The inaugura- tion of an active antisejitic treatment, though the temperature be very high, M'ill usually i)e followed by a remission if undertaken before ner- vous symptoms become severe. The treatment of septicaemia must have I'clation to prophylaxis as well-as to the later manifestations shown in the general condition. In the early stages it is mainly local, and means the application of all the rules and remedies of the so-called autisejitic surgery of to-day ; in the later period, when the heart threatens to give out, or the intestinal tract becomes irritable, or the brain is oppressed by the presence of a poison, the specific treatment of the disease, the antisepsis, becomes subordinate to that directed to overcoming these c(mditions of the general system. The projihylaxis of septicsemia, however, belongs to another subject ; it is included in the treatment of all wounds, whether operative or otherwise ; it has to do with the jireparation of the patient for an operation — the operating-room, the instruments, dressings, the operating held, the per- sonal cleanliness and disinfection of the surgeon and attendants of every grade, or, when these are not at hand as in a well-regulated hospital, to aim for them as far as possible, supplementing them, however, with remedies having in view the destruction of infectious substances which may have gained access to the wound before the care of the surgeon is 394 SEPTICAEMIA, PYJEMIA, AND POISONED WOUNDS. given it. It would, however, involve a repetition if these matters were given at length here ; they will be treated of under the aseptic treat- ment of wounds. We have here to speak only of the treatment of wounds whieh have become infected : wliether this be from the fault of the surgeon in not having achieved the desired asepsis, or from the nature of the accident and its surroundings, is indifferent; its existence is determined when the conditions heretofore described are foinid. If the wound has become infected, the treatment is started antisep- tically at once. The two princijial methods are the dry and the moist. The first is founded on the well-known fact that the development of bacteria requires heat and moisture : if either of these be absent — /. e. if the temperature be near the freezing-jjoint or if the parts be absolutely dry — no putrefaction can take place. The first of these conditions is, for obvious reasons, impossible of fulfilment, but the latter, if the wound be not very large or ragged, may be approximately, often suf- ficiently, achieved by the employment of materials of various kinds which will absorb the discharges of the wound and A\ith that sterilize the soil in which the micro-organisms breed. Iodoform, l)oric acid, bis- muth, inditferent substances, as starch, lycopodium, have this in common, and when freely applied with a thick sterilized dressing, as gauze, dried moss, jute, oakum, or even absorbent cotton, over them, \\ill occasionally serve this })urpose. The application of this method is, however, limited : it requires that the wound shduld be fairly smooth, with a minimum of ragged edges or exposure of smiace, and that the secretion should not be very abundant : this occurs only in quite recent Avounds. When the wound is extensive, not capable of nearly complete closure, has a quantity of ragged edges and exposed muscles, with the intermus- cular spaces and connective tissue leading along the vessel-sheaths laid bare, in every one of \\hich the secretions of the wound collect and serve as fertile breeding-grounds for the bacteria, it is necessary that some means be employed either to remove them or to destroy the germs and their spores in situ. For this purpose various antiseptic solu- tions are employed in many different methods to suit exigencies and to meet mechanical difHculties of situation, etc. There are three princij)al methods of applying the moist dressings : first, intermittent washing of more or less frequency ; second, constant irrigation ; tiiird, application of dressings wrung out in various solutions or combinations of these solutions. Appreciating the importance of rest in every healing wound, as little disturbance as is consistent with the thorough removal of the infectious matter should be employed : we judge of the thoroughness of the removal by the effect on the temperature. The washing is done most conveniently with a so-called fountain syringe or irrigating bottle suspended above the level of the wound, to get the amount of force required to inject the washing fluid into all the interstices of the wound, using best a glass point for ct)ntact with the wound (in a hospital a sepa- rate point is kept for each patient), which in the intervals between use is kept in an antiseptic solution. As warm water is usually more grateful to the jiatient's feelings than cold, it is in most cases best to use it ; there are cases, however, when the j)utrefaction is active, in which the inhibiting efl^ects of cold on the devel- opment of the micro-organisms may be tried with advantage, especially SEPTICEMIA. 395 if the bodily temperature be high, inasmuch as by reducing this we are restricting the activity of their reproduction. Having regard, tlien, to the temperature, the wound may be washed off with simply sterilized water ; with a solution of carbolic acid from 1 to 5 per cent. ; with mer- curic bichloride of from 1 : 500 to 1 : 20,000 ; with potassium perman- ganate of from 1 to 10 per cent. ; with hydrogen peroxide of from 1 : 1 or from that to 1 : 15 ; with Tiiicrsch's solution ' — according to the effect to be produced as shown by the odor and the degree of temperature. This is but a small list of the remedies recommended : tliey are, lH)wever, those in principal use, having stood the test of practical applications in many different hands and under various conditions. As to a choice between them, one is guided by idiosyncrasies of individuals and the effect on the tissues. CJarbolic acid produces an unpleasant anses- thetic effect on the part if allowed to remain in contact witii it long or if used in sufficient strength to be a germicide. JMercurie bichloride is the best germicide, but acts unfavorably upon the tissues themselves, and there is always the further danger of sidivation if used freely. Potassium permanganate is expensive and stains everytliing with which it comes in contact, whereby the local process is hidden and one is at a loss to know what is going on in the wound ; indeed, later investigations seem to show also that its disinfectant properties at least have been over- rated. Hydi'ogen peroxide, which has been extensively advertised and lauded to an extent in some quarters that renders one suspicious, has very decided objections : it is expensive, is extremely uncertain in quality of manui'acturc, requires particular care for its preservation, and if used I'reely will salivate. For these reasons it is not adaptable for ordinary use. Taking it altogether, mercuric bichloride meets the indications for practical use the best, though it requires care about the sick- room in that tiiere is nothing in its appearance or smell to distinguish a solution of it from water. Pharmacists have met the demand for its use by preparing tal)lets combined witii ammonium (or sodium) cidoride of definite strength, one of which, dissolved in a ])int of water, makes a solution of 1 : 500, and with this as a standard the strength may be varied according to the indications. In order to identify the solution, tablets are occasionally colored with some indifferent coloring matter. In the hands of the laity this may be a wise precaution, but the solution is disagreeable to work witli, to say the least. In case of extensive laceration of skin and more or less exposure of underlying tissues, where a loss by slough is inevitable, and where, under ordinary circumstances, the slougiiing process would surely be accompanied by a septic process of considerable if not dangerous inten- sity, where the prac'tical indication is tlie apjdication of a poultice to hasten the process of separation, my practice is to ajiply a thick layer of cotton or jute or mixed tissue freely wetted \vith a hot solution of mercuric bichloride of about 1 : 4000, covered with a rubber clotii or oiled silk to keep it from drying ; this, which I call an antiseptic poultice, is changed every few iiours (dej)ending upon the urgency and the effect produced) by rinsing the dressing oil' by wringing it out once or twice with a fresh solution, and is again ajiplied hot. By this means I am frequently able to treat an extensive slougiiing process with little or no ^ Salicylic acid, 2 ; boric acid, 12 ; boiling water, 1000 : jiarts by weight. 396 SEPTICEMIA, PYJEMIA, AND POISONED WOUNDS. febrile movement. A cnsc! in point occurred in a man the bottom of whose foot had been ahnost torn oil' in a "planer," the injury being very similar to the one above cited of f/ciiif/rene fond roy ante, but in which I was able within a few hours to institute the treatment above described, and, although the suppurating process lasted several weeks, it was throughout its course absohitely odorless and afebrile. This ex- tremely favoral)le course, however, is jtossible only when tlie treatment is instituted early, bclbrc the septic j)roccss has l)egun : it is really asep- tic treatment, and not the treatment of sei)tic:cmia. It shows, however, what may be accomplished by that method of treatment, for frequently Avhen the septic process is already in full swing the ap|)lication of an antiscpti(> poultice as described will reduce the activity of the process or stop it altogether. If it does not, the dressing may be removed every two or three hours, the wound thorougldy ^vashed out in every part of the interstices with a solution of 1 : 2(J(X), and the poultice reapplied, carrying it well up to above the limit of the wound. In severe cases a more frequent change is required, and the solution should be allowed to drip constantly over the dressing, provision being made to carry it off: in aggravated cases a stream of the solution may be arranged to play constantiv over the wound, at once disinfecting it and washing the loose and soluble products of decomjjosition away. This constant irrigation, however, requires caution, as it may salivate, and it should therefore not be used in greater strength than 1 : 10,000 for any length of time. I sometimes alternate the washing off of the wound with the solution once in two or three hours, with irrigation of sterilized water to wash away whatever sublimate may have remained on the surface or in the interstices of the tissues. Depending, hence, upon the temperature and the local swellings, the strength and the length of time of the appli- cation are to be judged, varying from intermittent washings of sterilized water to constant irrigation with a sublimate solution. The entire submersion of an extremity in an antiseptic solution is practised in some cases when the laceration is extreme and the mechan- ical ditticidties in the way of a thorough irrigation cannot be otherwise overcome. Following the practice first observed at the Massachusetts General Hospital, I have used the coal-tar product of sulphonaphthol in the proportions of from 1 to 5 per cent., the usual strength being 2 per cent. The limb is kept innnersed in this solution for a few hours, the moist dressing sul)stitutcd, and, if the temperature rises, the limb is reimmersed : I have used this quite siitisfactorily in cases already septic when admitted to the hosjiital. The objection to it is a liability to pro- duce dermatitis of the healthy skin above the seat of the injury, and a shininess of the surfiice where the moisture, which bears a certain re- semblance to an emulsion, comes in contact with the raw surface. Patients, however, usually express themselves as relieved from pain in a short time. " Creolin " may be used in the same way. Incisions through the skin into the swollen tissues to allow the escape of the infiltrated serum serve also as avenues through which the solution may be injected into the tissues where the products of putrefaction are developing : these incisions often require to be numerous and deep, and are frequently the means of saving a limb or life that otherwise would be sacrificed. SEPTICEMIA. 397 In septic lymphangitis and adenitis it is sometimes also necessary to dissect out tlie contents of tlie axilla or groin, whicli have become foci from which the septic process is further distributed. Unfortunately, however, none of these precautions or remedies is suflticient to clieck the onward course of the disease : the piilegnionous process extends near and nearer the trunk ; more and more of the limb becomes gangrenous ; the fever becomes woi'se, the brain symptoms more pronounced ; it is evident that unless the patient is relieved from the continued absorption of the putrefactive products death will ensue. Under these circumstances the removal of the whole limb is an imperative necessity, and witli it comes the decision of the seat of the amputation. Will it do to operate through soft tissues already infiltrated witli the products of decomposi- tion, or must the whole limb be sacrificed, adding to the dangers of tlie operation, already very great? While such a thing is of course undesir- alilc per sc, and, other tilings being equal, is to be avoided, yet operation through infiltrated tissues is not absolutely forbidden. It depends upon the character and extent of tlie septic ])rocess. One cannot advise cutting through a gangrenous tissue or one in the immediate neighborhood thereof, but I have repeatedly, under stress of circumstances, amputated in regions where the tissues were infiltrated and discolored, and witli care have had recovery. I have in mind a man who was cut on the foot with an axe wliich passed deeply lietween tlie great and second metatarsal bones ^\'itll- out injuring either, but in whom the \vound b(!came infected : gangrene appeared in isolated spots on the leg above the ankle ; tiie jiatient's gen- eral condition became exceedingly bad — could hardly be worse ; pulse and temperature both high, and, quite incapable of appreciating his condition, he lay in a muttering delirium. The local a])pearances grew worse, tlie gangrenous spots appeared aliout the knee, and in desperation amputation was performed at about the junction of tiie middle and U])j)er thirds of the leg as the highest point at which it was believed he would survive the shock of operation. He was so torpid by the eifect of the poison on his brain that he required almost no ether ; he was unconscious of tiie operation for several days after it was over. The cut surface hardly bled ; it was discolored and dirty with sanguineous serum ; the arteries were occluded. There was no odor to the Jreshli/-cut surface or stump aftertcard. There was no union by first intention, the skin-flaps became gangrenous along their edges, and yet the patient in time got well with a useful stump. This was an extreme case, and very doubtful in progress for a long time, but the end justified the rislv ; and, as less severe cases have also recovered, it can be claimed that while the practise is not desirable as a rule, it is sometimes good surgery. An elevated position to the aftccted limb, if it be such, is most desira- ble, and the importance of rest in keeping the circulation as inactive as practicable is not to be forgotten ; therefore the suspension of an arm or leg is to be practised if possible. As to the treatment of the constitutional complications which occa- sionally arise, we are guided by general principles. The disease is from the beginning depressing, as shown in the lieart's action ; stimulants of all kinds are therefore allowable, the choice being left to the taste of the individual (surgeon). The necessity and the amount required are indicated quite as much by the dryness or otherwise of tlie tongue as by anything 398 SEPTICAEMIA, rV.EMIA, AXI> POISONED WOUNDS. else, thougli the state of the jHiLse of course is to be considered. Brandy, St. Croix rum, B(inrhon whiskey, in about the order mentioned, witii tiie bitter tonics of cinciiona and gentian, are the most desirabk'. If tiie patient can take milk, this in the form of millv-])uneh and egg-nog gives nourishment with the stimulation; if there l)e vomiting, "ginger ale," champagne, and carbonated water will frequently control it, and I have known fresh buttermilk to be retained wiien every other form of nourishment was rejected. Other forms of intestinal disturbance, as diar- rli(pa, are to be treated by the ordinaiy astringent and sedative remedies of acetate of lead, opium, catechu, tannin, etc. I iiave sometimes thought that good results in the beginning of an attack followed tiie admin- istration of a brisk saline cathartic, wiiich ap])ears to reliexe some of the toxic symptoms, and the opium is then better bcn'ne. When a diar- rhoea occurs, it is best to stop the use of the mercuric bichloride and substitute something ha^'ing less tendency toward intestinal irritation. If the diarriicea becomes dysenteric in ciiaracter, euemata of opium and starch and lead will frequently stop it. Great care must be taken in the nursing of patients in the severe cases, as the stupor is so great that the skin over prominent points becomes ulcerated, and bed-sores of great extent and obstinacy result. This is especially tiie case when the urine and freces are discharged involuntarily. Tiie patient should, if possible, lie upon an air- (or water-) bed, or, if that is unattainable, air-cushions and ring-pads, to take tlie pressure from the threatened jioints, and, above everything else, the most constant, unremitting attention must be given to keeping the patient clean and dry. Use frequent bathing with alco- hol or cologne, dusting zinc powder or starch or lycopodium upon the parts afterward, and ciiange the ])osition from back to side and from side to side as much as the proper treatment of the local disease will permit. It must be remembered that the disease is most exhausting, and convalescence is correspondingly slow. Pyemia. A secondary fever with certain constant characteristic diurnal feat- ures, coming on in tiie course of the healing of a wound by suppura- tion, has been known since the earliest medical writings. In the wars of the Middle Ages epidemics of such a fever attracted the attention of Ambrose Pare and of Paracelsus. The former noticed that fractures of the liones of the skull by sabre cuts, etc. were followed by abscesses of the liver ; Paracelsus, that the fever was intermittent, commenced with a chill, and was frequently accompanied by inflammation of, and purulent deposits in, the joints. Morgagni described the abscesses as metastatic, and stated that the pus was carried to various internal organs — tlie lungs, liver, spleen, etc. — and tliere dept)sited from the blood-ves- sels ; he described an exudation into tiie pleura also as the result of puru- lent absor]ition from a wound. Tiie intermittent tyjie of the fever and its epidemic ciiaracter led to the opinion that it was of miasmatic origin. Mod- ern research, however, especially Vircliow's investigations on embolism and thrombosis, the experiments of Billroth and Otto Weber, and finally those of Robert Koch on the traumatic infective fevers, demonstrated that we have to do with the absorption of pus infected with micro-organ- PY^JIIA. 399 isms ; and the definitiou of Gussenbaur is now regarded as correct — viz. pyismia, or purulent fever, is " a general infective disease which arises from the entrance into the blood of the constituents of infected pus. It is distinguished from other septic infective diseases by the development of multiple abscesses in various organs, and by an intermittent fever." ' A pre-existing supjjuration, which implies a process of several days' or weeks' duration as the source from which the infected pus is derived, is the almost constant rule in pyajmia, though there are exceptional cases in which the injury — not always an open wound, even — and the general infection run a sinudtaneous course, with the general symptoms of a septic;emia rather than those to be described as characterizing pytemia, but where the autopsy discloses the presence of metastatic abscesses and purulent exudations. There are others, again, in which the original wound has healed, but the general disease has afterward occurred, running to a fatal termination, mIicu the autopsy again shows multiple abscesses and purulent exudations in the serous cavities and joints. Making the post-mortem appearances the diagnostic criterion, we learn that pyffiuiia may occur as either a primary or a secondary fever — that there may also be a period of incubation after the reception of the injuiy, with no general or local symptoms, during which the infection is, so to speak, working like an exanthematous fever, the general disease breaking out subse((uently and running its course indejK'ndently of the original injury, ^\'hen venesection was a more frequent j)ractice such cases occurred more often than they now do. Pyaemia may run an acute or a chronic course, more frequently the former, death occurring in the course of from five to fifteen days ; it may, however, last many months. It must be understood, at the same time, that the division is principally clinical ; the pathology is the same — viz. the entrance into the blood of the elements of infected pus ; and this differentiation has to do, first, with the amount taken up at any one time, and, second, with the power of the individual to M'ithstand the in- fection. An attack of acute pyaemia may, though it is unusual, subside into a chronic course, and, rice i-ersd, one that has been pursuing a chronic course may quite unexpectedly become acute. The course of a typical case of pyaemia is, in general, that at a \'ari- able period after suppuration has been established, the wound granulating and the dischai'ge creamy, in all respects the M'ound pursuing a normal course, the patient has a chill — variable in intensity from a crawling along the back to the teeth chattering and the extremities shaking, in difi'crent cases also lasting variably from a few minutes to an hour or more. This is followed, sometimes accompanied, by an increase of temperature, which may rise two or three or even more degrees, fall- ing to normal or below the -next morning. This succession of chill and fever, with morning remission, may occur daily or every other day, and the likeness to malarial fever becomes marked. Along with the febrile movement there is a condition of general malaise — loss of ap])etite, thirst, and headache, with some sleeplessness ; the patient is quite aware that he is not so well, and, if he be from or in a malarial district, will himself insist that he is suffering from malaria, the sub- jective symptoms are so identical. At the same time, or perhaps ante- ' Op. cit., p. 158. 400 SEPTICEMIA, PYJEMIA, AND POISONED WOUNDS. cedent to the febrile movement, the wound indicates that something has taken place to interfere with the healing process. The suppuration ceases ; the granulations become ]iale and ilabby, and may break down entirely, leaving the wound with a thin, dirty, sanious discharge ; the edges of the wound becc>me swollen and (edematous ; frequently we are able to detect cord-like swellings along the course of the larger veins leading from the j^art : these are hard and tender to the touch, and may extend some distance up the limb toward the trunk. The limb will soon after swell in its whole extent, the prominences and depressions become obliterated, and the natural configuration of the limb quite lost. The repetition of the chills and febrile movement continues with greater intensity, frecpiency, and irregularity ; the alternations with subnormal temperature are more marked, falling sometimes to 95° F. or less, only to rise in a few hours to perhaps over 104° F. This great range, repeating itself for several days, irregular as to the time of day, is a striking feature found in almost no other condition. The patient emaciates rapidly, the tliirst increases, the appetite fails, the tongue becomes red and dry, the skin, alternately bathed in sweat or abnor- mally dry, is apt to become yellowish in color, due not so much to inter- ference with the function of the liver as to a change in the blood itself, the coloring matter being liberated [lufmator/enous ictcrua) by destruction of the red blood-corpuscles ; the pulse increases in frequency and be- comes weaker. In contradistinction to septicaemia, the mind is not often affected ; instead of Ijeing apathetic and somnolent, the patient is con- scious of his weakened condition, often wakeful, and annoyed by lights or sounds, and likely to be querulous and complaining. In cases which run a protracted course the breath frequently exhales a peculiar mawk- ishly sweet odor, compared sometimes to newly-mown hay, and the patient complains of a disagreeable taste always present. As the disease progresses secondary involvement of distant organs or parts becomes evident ; the patient complains of pain in moving some particular and usually distant joints : it simulates rheumatism at first, and is frequently mistaken for that disease. The joint is tender on pressure or movement, red and swollen, but in the course of a few days fluctuation appears, and on puncturing or incising it pus is found : this condition may occur in several joints if the patient lives long enough. Other situations in the extrem- ities — the subcutaneous connective tissue, the muscular interspaces, even the muscles themselves — are not infrequently the seat of the metastatic abscesses, and particular mention must be given to their occurrence in the medullary canals of the bones, where they may be undetected until they have made extensive ravages, or be only discovered at the autopsy. Their presence is to be suspected when the patient complains of severe pain in the bones with exquisite tenderness along the shafts : the slight- est movement is agony. At first the tenderness is usually located at distinct points, afterward, however, extending over the whole bone. At first there is not much else than the jiain, Init later the tissues over the bone become oedematous, and, if the patient lives long enough unrelieved, other evidences of pus in redness and fiuctuation become manifest, and by incision the involvement of the bone is shown in the loosening of the peri- osteum. Like the disease of the joints, the resemblance to rheumatism at the outset is considerable, in both the local and the constitutional symp- PY^3IIA. 401 tomatology ; it is not until latei* that tlie true condition becomes locally manifest. It is therefore necessary to be keenly on the alert in the case of a suppurating wound to detect these evidences of transference to distant parts, because if the treatment be initiated early there is a chance of saving- life or limb, which chance, however, grows rapidly less as the suppuration extends through the whole bone. In the beginning the abscesses, as in other situations, are single or isolated, but they increase in number and run together until the whole canal is occupied with pus. Of other accessible organs, the secondaiy abscesses are to be looked for in the jxirotid and thyroid glands, and exceptionally in the testicle. Metastatic deposits in the internal organs often go undetected, their presence being, of course, by no means so evident as in the situations mentioned. Indeed, the special symptomatology of abscesses in internal organs — and they may occur in almost any — is^ not characteristic : in the lungs there may be cough and expectoi'ation, with some dyspnoea, but so long as the abscesses are small there is little to judge from. With pleuritic exudation, however, the evidences of dyspnoea, with dulness on pressure, faintness or absence of respiration- and voice-sounds, indicate the con- dition ; sometimes there are the other evidences of pleurisy — the inabil- ity to take a long breath, difficulty in lying upon one side or the other, and increase in frequency of the respiration. Icterus is liable to l^e present in metastases into the liver, but, as this is also present as the result of the destructitin of the red blood-corpuscles in hajmatogenic icterus, tlie condition is not diagnostic of the metastases unless it be associated with increased area of liver-dulness and localized tenderness, with possibly a tumor if the abscess become very large. In splenic involvement the increased area of dulness is almost the only sign to indicate the local trouble, and it is a further source of confusion if the question of malaria comes up. The spleen is, however, one of the rarer seats of secondary deposits. The only case of secondary pysemic abscess in the muscular tissue of the heart that I have any knowledge of I saw at the autopsy of an Italian laborer who died in the New Haven Hospital after an illness of nearly two months. This case will be referred to again in speaking of the mixed form of pyosepticsemia. We have learned that a typical case of pyjemia consists clinically of — first, an open suppurating wound ; second, a chill; third, a fever and sweat, these occurring irregularly ; fourth, thrombosis ; fifth, metastatic abscess ; sixth, death in the course of two weeks ; but, except the meta- static abscess or serous exudations, nothing is constant. As stated in the beginning, an open suppurating wound is not an absolute or constant feature. Wunderlich reports that a young working-woman suffering with an ordinary 'coryza wet her clothes during a hard day's work in which she perspired freely. The next morning, on getting up, she became faint and fell, injuring her right hand. Recovering conscious- ness, she was seized with a heavy chill which lasted some time ; she had pain in her sternum, headache, vertigo, and diarrhcea. She died on the fourth day in collapse, having had a continuous higli fever with erythe- matous bulhe on both feet. The autopsy siiowed a slight effusion of blood in the injured hand ; the blebs on the feet were filled with hem- orrhagic pus; the joints of both hands and feet were normal, as also the Vol. 1.-26 402 SEPTICEMIA, PYJEMIA, AND POISONED WOUNDS. vessels of the extremities, but tlierc wei'e luiiltiplc abscesses in the thyroid gland, the liver, and the kidneys, fresh extravasation in the brain, purulent myocarditis, pleuritis, ledema of the lungs, and a softened spleen. Gussenbaur reports the case of a physician who iiad a boil following the examination of carcinoma of the uterus wliieh healed vp completely, and three weeks after h(> became ill with afternoon fever, bronchitis, double-sided empyema, and tedema of tiie lungs, from which he died on the fourteenth day. The autopsy revealed, besides the pleural implica- tion, multiple abscesses in the luugs, a large abscess in tiie liver, and a softened spleen. Although the ciiill is by far the most frequent inauguration of the proper pysemic process, every surgeon wiio has much to do witii tiie disease recognizes cases in which it is wanting or first appears after the fever ; and, further, while the repetition of the chill is the rule, it .some- times does not reappear at all. Tiiese variations, iiowever, have no appreciable effect on the course of the disease nor on the termination. Billroth remarked, iiowever, that disturl)anee of tiie wound was very apt to be followed liy a chill ; dressings of the wound, probings, and reposition of fragments of broken bones were followed by chills in the course of from two to six hours ; it was remarkable how frequently the morning and evening visits of the surgeon were followed by chills. While the type of pyemic fever is tiie intermittent, this is not abso- lute. The " pyiEuiic curve " of the temperature cliart lias liecii spoken of as though it were something positive and pathognomonic, but it has just been shown that the fever may be continuous, the fact being that it depends largely upon the severity and rapidity of the infection as to whether this variation in the height of the fever is marked or not. It also presents variations, even in its intermittence, wiiich are to be noted, and which make the diagnosis doubtful if we depend upon the chart alone to determine it. The fever will sometimes rise by gradual steps, as between morning and evening, in the course of two or three days, to a considerable degree, 103° F. or over, then fall either as grad- ually or suddenly to normal, giving rise to the hope that the infection has been eliminated, only, however, to repeat the process of elevation. At anotiier time in the same case tlie temperature will go suddenly up for a day, and in the next few hours fall again. Individual cases being liable to these striking variations from tlie type, little can be judgeil of a given case from the chart alone, except that great and repeated varia- tions from subnormal to very high tenqierature after a suppurating wound indicate that infected pus lias gained entrance into tlie circulation. As an instance of the great variations in the temperature occurring in a few hours, and also of the great irregularity in the course of the fever, take the accompanying chart of the course of an acute pyaemia in a child of about five years of age, paralyzed with a spina bifida, who was admitteil with a great bed-sore alongside of and exposing the sacrum and coccyx. In spite of the utmost care after admission, it extended deeper, and after several months her temperature was one day found to be 101° F. in the morning, and slie was feeling unwell. The child was too young to describe her sensations, and there was no olijcctive evidence of a chill until later, but the variations in the temperature began at once, for on the second day it swung from 2?>f^° to 102/^° (4°), and on the third PY^3IIA. 403 day from 97^° to 104° between 5 A. M. and 12 m. (6^°) ; at 4 p. m. it had fallen to 98°, only to rise to 105-;^° at 10 p. M. (7^°), to fall the next morning, the fonrth day of the attack, to hclow 95°. As the clinical thermometer was not graded below 95°, it was too low to register, but it Fig. 13. Duyuf 1 •i s 4 i* «> T s 11 10 " 1 AM. P.M. A.M CM ..» Ip. M. A.M.iP.M A.M. H-.M A.M. P.M. A.M. P.M.

On the fifth day it oscillated between 98° and 103° at 4 p. M. to 104y«^° at 9 P. M., and the next moniiu;/, tlie sixth day, it was 105^°, to fall in the afternoon (in opposition to the rule) to 98-fL°, continuing to fall in the morning of the seventii day to be again bcloir 95° ; it only rose that afternoon to 97^°. It continued to rise botli morning and afternoon on the two succeeding days to 104y\°, and without further remarkably abnormal variations siie died at the end of the eleventh day. At the autopsy it was found that the bed-sore had cau.sed a necrosis of the .sacrum — that pus had invaded the right sacro-iliac synchondrosis ; there were numerous non-suppurating infarcts in the lungs, and in the left pleural cavity was a large aniount of scro-purulent exudation. Chronic pysemia is characterized clinically by a ftdrlv regular liut excessive diurnal range in temperature, continuing for weeks or months; few or no striking exacerbations of this range are noted, but it varies from 98° F. or below to 102° or over almost daily. This condition, which has been described as hectic or irritable fever, is associated with slight and infrequent chills, with great loss of muscular vigor, emacia- tion, a red hut not necessarily dry tongue ; there is constant thirst. Usually the ajipetite is good, lint the frerpient attacks of diarrhoea and the emaciation show that the digestive tract does not assimilate the food taken ; the ansemia becomes marked, the skin jiale and even slightly 404 SEPTICEMIA, PYEMIA, AND POISONED WOUNDS. sallow or yellow. The intellect is clear, the sensibilities acute, but, owinw to the extreme weakness, the patient remains in one position, sunken down in the bed, and lied-sores are liable to form : tliese appear especially in those who liave diarrhiea, owing to the difficulty in keep- ing dry. The patient sweats botii sleeping aud waking, and trembles at the slightest exertion ; even the effort of" speaking exiiausts, the voice trembles, and he weeps readily. Tiie termination comes by exhaustion from the diarrhoea, or an exacerbation of the attack carries iiim off in a cou])lc of days. There are undoubted cases of infective fevers in which the symptoms are sufficiently marked to justify the opiuion that products of decom- position in the wound and infected pus may be present at the same time, producing a septic pya'mia, or pyosepticannia as one prefers to call it. The clinical course of such a condition is characterized by prom- inent symptoms of both diseases, and the autopsy reveals the presence of metastatic abscesses. An Italian laborer thirty-six years of age, who had been working in a sewer, was admitted to the New Haven Hospital on July 10th with a very incomplete history, but the distinct statement that he had had " chills and fever" for two M'eeks. He was assigned to the medical division and treated for malarial fever. On admission his temperature was 103° F., and under treatment it fell to 99^° in the evening of the second day. His countenance was dusky, and he M'as somnolent most of the time, or talking in his sleep and breathing irreg- ularly, sometimes stertorously : his temperature rose again, however, and for the next three days it was irregularly between 99° and 101 j^° F. He had several loose movements of his bowels — Mas occasionally delir- ious, with twitching of muscles cf face and tearing at the bed-clothes. He drank plentifully of milk ; on July 14th a large abscess was found upon his right thigh and another on his right forearm ; these were evacuated and found to contain 6 ounces and 1 ounce of pus, respec- tively. The mental condition remained about the same, and the temperature arose the next morning, July loth ; after opening the abscesses (which were washed with an antiseptic solution and drained) the temperature arose to 101.8° F. The temj^erature for the next thir- teen days fluctuated daily from about 99° to 101 j^° F., on one occasion going up to 103^° F. At first his general condition improved and his appetite was good, but on the seventeenth day he refused liis food, as it distressed his stomacii, and he vomited oecasionall}'. He got over this, and his general symi)toms were more satisfactory again in that he ate and slept fairly well, with occasional lapses of his bowels, and his mental hebetude disappeared. On July 28th his temperature arose to 105° F., falling the next morning to 99 jij-°, and on the 30th it arose to 103j&5-°, to fiill to 100.4° ; and tliis was the last marked fluctuation, for the fever now became continuous, ranging for the next three days just across the 100° F. line, then for a couple of days at the 101° F. line; from this time, August 6th to 12th, it ranged across tlie 102° line, and on the evening of the 12th it arose to 105y*„° F. During this time his general condition failed ; he became weaker, had from time to time vom- iting and diarrhoea, with appetite in the intervals ; there was no change in the condition of the abscesses on his thigh and arm, and no other devel- opment externally. On August 8th a yellowish color appeared on the PYEMIA. 405 skill ; on the 13tli the teraiieraturc was lower, ami continued to fall, until, on the nioruing of the 14th, it was at Q9^jf° F., as low as it had been for three weeks. He died the following day, the temperature having gone up to 106y*^° at the last. The course of the disease was therefore about fifty days, but during all this time he was acutely sick. The autopsy showed the liver large, fatty, of a light color and jjasty consistence ; the spleen large, soft, and pulpy, with embolic infarctions. In the wall of the left ventricle of the heart (auriculo-vcntricular valves) there was an abscess, the size of a walnut, which luul opened into the ventricle. Both kidneys were enlarged, the left the most, with a great number of small abscesses interspersed through it ; the right liad a large abscess in the lower por- tion, with smaller ones in numberless quantity throughout the whole organ. Those in both kidneys were undoubtedly metastatic, and when one appreciates the abscess of the wall of tlie heart opening into the cavitv of the left ventricle, pumping pus into the circulation with every pulsation, the source of the countless abscesses of the kidneys becomes evident. How long it had been doing this could not be determined from the symptoms. The urine was repeatedly examined, but beyond a "trace" of albumin showed nothing abnormal. The treatment of pyaemia resolves itself, like that of other septic infectious processes, into local and constitutional, and the local into prophylactic and symptomatic ; and of the latter it must be said our means of relief are very limitetained a large size or had served as secondary foci. The certainty that the chill was the evidence of a fresh dejjosit of pus was the incentive to more careful searching, and in almost no instance were we deceived, and the patient recovered from a condition that seemed at times hopeless. Suppurating joints are to be freely incised and carefully washed out ; if tiie suppuration has spread into the neighboring tissues, amputation is to be considered, and has been performed with the result of saving life otherMise doomed. Similar advice should be rendered in cases of pysemic osteomyelitis, with even more insistence than with joints, for the medulla is a lymph- channel, and, being hidden, is just so far a more dangerous situation from wliicli tlie infected i)us may be spread. It is a matter of saving life rather than of conservative surgery. When throml)osis occurs, with the j)ossible sequence of embolic meta- stasis of the infected clot, the proposition has been made to in some way check the current of the circulation l^etween the thrombosis and the heart, and in this way to ])revent the wider distribution of the disease. Compression, isolation, and ligation of the vein have fmm time to time been em])loyed, and iu some cases with success. These are, however, unusual cases, and the practice has not become general ; the fact that all thromboses do not lead to emboli, that a fairly large number get POISONED WOUNDS. 407 ■well, makes it iueumbent on the surgeon to hesitate before undertaking an oiJeration that might possibly hasten the very process it is intended 'to check, but instead to try, by warm, moist antiseptic applications, sus- pension or elevation of the limb, and complete rest, to obtain regressi(m. Besides the local treatment, the general condition of the patient demands attention : the indications are to suj)port the patient by stinui- lants and tonics and to nourish by food. Milk-punch and egg-nog made up with St. Croix rum or brandy fulfil the therapeutic indications. Cin- chona is also frequently of benefit — whether the bark or its alkaloid is not of esjiecial importance, exce])t for the smaller dosage of the latter. Too much stress cannot be placed on the absolute necessity of an abun- dance of fresh air in the treatment of pyiemia and septicaemia. Poisoned Wounds. In poisoned wounds there is introduced at the reception of the injury some substance having a deleterious influence either upon the tissues at the point of entrance or on the general system, or on both, it being dis- tributed to the general system through the circulation, the deleterious result being out of all proportion to the injury received. The influence is .sometliing more than that of a foreign body wliich excites local action in attempts to get rid of it, and if prolonged gives rise to fever. It is difi'crcut from the morbific action of the toxines of septicemia induced by micro-organisms of various kinds. It is differ- ent, again, from wounds in which the diseased secretions of animals are introduced into the circulation, giving rise to the phenomena of disease at a later dav, as hydrophobia. It is the direct action of the substance itself upon the tissues (using the term in its largest sense) with which it is brought in contact, and the ettect j)roduced depends, in a given case, entirely upon the amount introducetl into the circulation. The poisons are both vegetable and animal : the former are usually introduced on weapons of warf\irc liy the natiA'es of the islands of the Indian Archipelago and of South America ; the latter, by certain insects and reptiles. In the East Indian islands the jioison is procured from incisions made in the bark of the upas tree, of which there are two species, the Upcw aiitinr and the Upaa ticute, the poison of the latter being the more active of the two. Fabulous tales have been reported of the effect of poisonous exhalations from these trees; these are now known to be untrue. There exudes from the incision a gum-resin, which is poison- ous taken internally or introduced into the circulation. The arrow- or lance-points are smeared with this resin, and the effects of the poison are great prostration, a feeble ir'.-egular pulse, vomiting, involuntary evacua- tions, convulsions, and death from cardiac paralysis. I am unaware of any direct antidote to this poison, or indeed of any investigations looking to that end, but, judging from the symptoms as detailed, the indications are for active stinmlation, alcoholic and diffu- sible. Tlie South American Indians use a poison variously named woorari, urari, or curare, which is i)btained from various species of Strychnos growing in the Amazon and Omnoco regions and in British Guiana. 408 SEPTICEMIA, PYEMIA, AND POISONED WOUNDS. An extract is made from the bark and leaves, and in tliis tlie points of the arrows arc dipped. It is very powerful ; a small quantity introduced into the circulation acts by paralyzini>; the motor nerves, shown first in a feeling of weariness and disinclination to move, followed rajiidly by complete paralysis of all muscles, inciudinjjj those of respiration, by which death comes, the heart acting after the respiration has ceased. In larger doses the vagus nerve and heart become paralj'zed. The action is quite rajiid, death occurring in a few minutes Avith fatal dosage. If the amount introduced be not sufticicnt to kill at once, life may be saved by keeping up artificial respiration until the j)oison be eliminated by the kidneys, which occurs fairly raiiidly. There is no evidence that the North American Indians have ever used poisoned arrows as such. The traditions to that end are based on certain rites with which they intersperse their war-dances preparatory to a foray. They mix up a lot of stuff in which jnitrcfying animal matter obtained from snakes and other reptiles enters largely ; in this they dip the pciints of their arrows, using various incantations of a semi-religious kind, in order that the arrows may be more potent against their enemies. This mess of course contains a great number of microbes of decomposition, which, entering the tissues at the wound, may produce scpticaMuia, and be so far poisonous ; beyond this there is nothing. Animal poisons are introduced either as stings or as bites. Stings are usually made by insects carrying the A\'capon at the posterior extremity of the body, the venom being secreted by a gland, and emptied into the wound at the time of puncture by the sting, which is usually barbed or serrated along its edges. The sting is really an ovipositor, consequently only females sting. Exceptions to this are found in certain gnats and bugs, of which the common mosquito and bed-bug are familiar examples: these sting by a proboscis, and both sexes are venomous, as is also the case with biting insects, of which the spider is the most common. The venomous sting-carrying insects Avith which the physician has principally to do are wasps, hornets, bees, and some species of scorpions. This by no means exhausts the list of poisonous insects, and there are some venomous flies, but they are rare. Care must be taken, however, to difierentiate between venomous flies and those which serve simply as carriers of infective material. There are no known scavengers compar- able to the common house-fly : frequenting and living upon decomposing animal matter, it may, and frequently does, carry the microbes of putre- faction and of infection to minute wounds, and thereby excite a septic process which kills. The action of the venom upon the human subject is similar in all. A local irritation of varying intensity is excited, depending upon the amount of poison injected. If there be enough of it, constitutional symptoms are excited, but there are great differences in individuals as to the amount required to produce such effects. It is also well established that persons may become in time immune to the actit)n of the poison ])y repeated stings : this is the experience of most people living contimiously in mosquito- infested localities, and with those who work among bees the effect l)e- comes less and less with successive doses of the poison, so that finally in each case the sting excites no more action than the simple jiunctui-e. Usually the sting produces much more pain than can be ascribed POISOXED WOUyDS. 40ft to the puncture alone, lasting some hours. In a very short time, a few minutes, after the puncture an area of redness surrounds the point, which also rapidly becomes oedematous : with the appearance of the cedema the centre becomes white, and there is then a swollen, red areola with a white spot in the centre, which itches and burns. It is evident that the action of the poison is first to produce a paralysis of the vasomotor nerves, allowing the dilatation of the blood-vessels for a considerable area around the puncture, but whether the white spot in the centre be due to a cutting off of the circulation by the swelling around it (Van Buren), or to a constriction of the vessels themselves l)y the action of the poison emptying them of blood, may be a question ; but, taking into con- sideration the fact that in severe cases there is a slough at the centre, I am disposed to regard the white centre as the innncdiate effect of the poison. Not infrecpiently tiie sting itself is broken off and remains in the wound : this occurs if, as is usually the case, the insect is knocked away at the moment of stinging ; if, however, it be not disturbed, the weapon is withdrawn entire. Where the sting remains there is the ad- ditional irritation consequent to the presence of the foreign body. Not infrequently there is vesication over the reddened area, and in a consid- erable number of cases the redness and swelling and irritation extend perhaps over the whole extremity, with considerable pain lasting for several days, even weeks, and a feeling of numbness with autesthcsia and stiffness in movement, showing that the nerve-trunks are affected in both their sensory and motor filaments. Usually a sting or two or three do not produce an effect upon the general system, but if there be a large number the constitutional effect may be great. Death has followed in a few minutes after tlie attack of a swarm of bees wliicli had been disturbed. The symptoms are referable to the heart and lungs : the pulse is feeble and irregular, the respiration hurried, superficial, and gasping, the countenance livid, the skin clammy ; there are great prostration and veritable collapse, in which condition the patient dies. Additional danger exists when the stings are in the vicinity of the air-passages from the swelling interfering with the respiration, death having taken place from a?dema of the glottis producing suffocation. Wounds in the mouth occur sometimes in eating fresh honey in the comb or in eating fresh fruit picked up from the ground with the insects upon it. The treatment of the local irritation, after removing the sting, consists in cold applications, with amnioniacal water if agreeable. The indications for general treatment depend a little on how the heart is acting : if that be fairly strong, anodynes may be given to allay the pain and irritation, but if it l)e feeble, both alcoholic and diffusible stimulants must be used ; besides the usual forms of alcohol or brandy, whiskey, etc., the preparations of amnuniia, carbonate or muriate, and camphor, may be exhibited, together with hypodermic injections of digitalis, nitro-glyceriu, and strychnia. Many varieties of spiders arc venomous, the tarantula being perhaps the most so, but scorpions, galeodes, centipedes, are all more or less dangerous. The effect of their bites is in the main similar to that of stings, as just described, but they are apt to be more severe, leaving their effects upon the nerve-trunks much longer. These animals are usually shy and keep themselves hidden until disturbed, and then rush out from 410 SEPTICEMIA, PYMMIA, AND POISONED WOUNDS. inipxpec'tcd places, retreatinsj; ao;ain to tlicir hiding-places. The taran- tula, luiwever, iiiiist be reoartlcd as an exception, as it is liable to be quite piiirnacioiis, attacking animals much larger than itself" most vigorously. The hiding-places are oftentimes quite unexpected, as appears from an account in the Australian Ilediml Gazette for June, 1894, in Mhieh three cases of s])ider-l)ites upon the penis are detailed, the nesting-jdace of the animal being under the seat of an out-of-doors privy closet. All the cases occurred in the month of Marcli, and in each case the exami- nation of the locality revealed a brood of spiders of the genus Lathro- dectus, consisting of a mother with from twenty to thirty young ones ; and Dr. Parry, who reports the cases, suggests that they are venomous only during the breeding season : it is jirobable that they are simply more easily excited to attack at this time, owing to the maternal instinct. In these cases, besides the usual local effects of a burning pain and swelling, the remote effects on the nervous system were .shown l)y the occurrence in the course of a couple of hours after the injury of an exceedingly disagreeable pain, as of pins pricking him, in the patient's toes : this gradually spread up to his ankles and knees; the part became bathed in a cold perspiration. The temperature Avas .sligjitly sulinormal and tiie heart's action feeble. The pain continned for forty-eigiit hours, and the perspiration, conhned at first to the lower extremities, became general, and so profuse as to soak through the blankets on the bed. It gave off a peculiar, very offensive cadaverous odor. The patient was exceedingly restless, unable to sleep without anodynes, and suffered pain all the time. He was confined to his room for five days, but for two weeks there were darting jiains through his legs and around the lower part of his abdomen. Dr. Parry regards the lesion as that of a peripheral neuritis. Of poisonous serpents there are four genera in this country — viz. of the rattlesnake there are two, the Crotahis, with fourteen distinct species, and the C'«(/(//.so(i«, with four; the copperheads and moccasins are of one genus, the Aricistrodon, divided into four species; the vijjers Ektps are of five species. The first three genera above mentioned have movable poison-fangs situated in the njijier jaw, which ordinarily, and always when the mouth is closed, lie folded back and are concealed Ijehind the upper li])s, Imt which on opening the mouth widely are capable of becoming erect. The viper has small permanently-erect poison-fangs, situated fai-ther back in the jaw than in the Crotalidfe. In Europe the viper, Pelias berus, is the only venomous serpent met with, and, as comjiared with those of America and India, it is ahuost harmless ; deaths from viper-bites are extremely rare in Europe. It is in India, however, that the venomous snakes are met with in the greatest number, variety, and virulence, the mortality from snake-bites being very great. According to Sir Josej)h Fayrer, the deaths fr( im snake- bites alone are about 1 : 10,000 of all deaths. The iirincipal genera are the cobra Naja, or hooded snake, the krait Bungarux, the ophiophagus, and the daboia. The first named is the most venomous known and is the most frequently met with : nearly one-fourth of the deaths from serpent-bites are caused by the cobra. Next in frequency are the kraits ; then ojjhiophagus, a large and very ferocious snake, having the habit of fe POISONED WOUNDS. 411 devoui'ing other snakes, lience the name ; the daboia is of tlie viper genus and most venomous of its race. There are many other genera, but thcv are rehitively unimportant, except as showing the great numbers in that country. The true Hydrophidea (water-snalies or sea-serpents) are found principally in the neighborhood of the islands of the Indian and Pacific Oceans and of the seas between China and Australia. They are exceedingly venomous and somewhat aggressive, but not large, usually less than five feet in length. The mechanism of the poison apparatus is essentially the same in all. The venom-gland, analogous to the ])aroti(l, i* situated upon the superior maxilla below and behind the eye ; it is a flattened oval in shape, taper- ing forward to a duct leading to the base of the fang in front. There is no especial sac or reservoir for the collection of the venom, but as the duct runs through the centre of the gland it dilates a trifle, and in this there is a small store of venom collected. The fang itself is not, as is commonlv supposed, movable at its attachment to the jaw, but that por- tion of the maxilla witii the fang inserted in its socket is attached loosely to the rest of the bone, and on dilating the mouth widely this portion of the jaw turns in such a way as to bring the point of the fang to project downward and a little backward ; with the closure of the jaws, the fangs being erect, they are driven into the skin if it lie an animal : tlic temporal muscles press upon the gland and squeeze the poison out into the duct and along the groove in the posterior edge of the fang, and it is thus led to and injected into the tissues of the animal attacked. The fang itself is very sharp, sickle-shajicd, with the concavity back- \\ard. The erection of the fang is a voluntary act in itself, not the effect simply of opening the jaws widely ; the mechanism is quite com- ])lex, but it is luinecessary to describe it here. In feeding the fangs are not erected, but are kept folded l^ack and covered by a sheath of mucous membrane. The poison is ejected with considerable force, sufficient when it misses its mark to throw it five or six feet away. In the vipers the fangs are permanently fixed, and are situated farther back in the jaw than in the serjients aljove described ; they are not so long or curved, and the groove is not so deep. The gland is not so large, either ; the jaws eann(jt be opened so widely, and the muscles do n(3t act with so much force. Taking it altogether, it is a much less effective mechanism, and in consequence vipers are not nearly as ])oisonous. The effect of the injection of the venom is a " swelling at that point, with intense violet-black discoloration of the skin, whieli gradually extends over an area of several scpiare inciies. The tissues in the immediate neighborhood are soaketl with extravasated blood. If death occurs soon, local ex'ti'avasation may be all that is visible, but if it be post- poned for a short time, then smaller extravasations are found in distant tissues. Most frequent and most ])r()uounccd are subpleural, subperito- neal, and subpericardial ecchymoses, l)ut tlie whole organism is deeply affected, the tissues being congested and presenting a much darker apjiear- ance than normal. The blood does not seem to coagulate readily within cavities or interstices of the body unless death follows almost instan- taneously. In cases which live longer the blood remains constantly in a li(iuid state or coagulates imperfectly, and then only after being 412 SEPTICEMIA, PY/TIMIA, AND POISONED WOUNDS. exposed to the air, resembling in tliis particular the state of that fluid observed in conditions of asphyxia." ' The symptomatology is similar for the different genera, the diiferences being due to the amount of venom injected and individual susceptibility. Besides the points just given, the whole limb swells, ecchymoscs a])pear under the skin and s:uiious vesicles upon the surface, and if the patient lives the skin directly about the wound becomes gangrenous. The con- stitutional symptoms are of great severity and rapidity : the pulse is feeble and fluttering ; at first nausea and looseness of the bowels may occur, followed by involuntary evacuations of urine and faeces ; there is great difficulty in breathing, with pain about the prsecordia ; at first there are great anxiety and restlessness, but as the effect of the poison extends to the nervous system the sufferer becomes delirious, then indif- ferent, then somnolent, and dies in a state of coma. The time of death varies from a few minutes to several hours after the bite. In non-fatal cases there is considerable variety in the symptoms, and cases are reported of singular delay in their appearance. Thus, Dr. Yarrow^ states that constitutional symptoms were not present until four days had passed, the local symptoms also being sim])ly troublesome; but with the coming on of the constitutional symptoms the local became more active, simulating phlegmonous erysipelas. The ])atient continued to grow worse for twelve days, when under treatment the disease took a favorable turn, and he eventually, in the course of about four months, recovered. In other cases, again, there arc recurrent symptoms, coming on after intervals of varying length ; nor are the symptoms themselves constant. Dr. Piifard of New York reports a case where a vesicular eruption appeared at varying intervals of from three months to a year in a young woman whom he first saw six j^ears after the bite. Dr. Cole- man reports a scaly eruption resembling ichthyosis coming on in two successive years after a venomous snake-bite (variety not given), and Dr. Yarrow's case had marked constitutional symptoms at about the anniversary of the bite, Avith a good deal of local reaction : he reports two other cases having similar experiences. The evidence of these recurrences comes from too reliable observers to be ignored. It is diffi- cult to explain them, but that they have to do with a neurosis is quite evident. The evidence that the Hdodcrma Ruspedum (the "Gila monster"), a lizard found in Northern Mexico and the South-western United States, is poisonous is too conflicting to allow a positive expression of opinion, the latest experiments by Dr. Yarrow being altogether negative, though most careful observers have thought it is poisonous, the grooved fling indicating poisonous qualities. The treatment of venomous snake-bites, to be efficacious, requires to be of the most energetic character. The first aim is to prevent the poison from getting into the general circulation, or to have it enter in such small quantity and so slowly that it shall not act powerfully on the nervous system — that its action be delayed. Therefore tie a ligature as tightly above the bitten part as jjossible to be borne : the larger tlie ^ Mitchell and Eeichert : " Researches on the Venom of the Rattlesnake," Smithsonian Contributions to Knowledge, No. 647, p. 139. ^ Amer.

Then the part may be suckeil (with sound lij).s), but, better yet, let it be excised freely and deeply, the sucking applied afterward, and bleeding facilitated. I can see no good to be accomplished by cau- terizing : the wound is too small to be followed into its recesses by any caustic liquid or solid, and nothing is gained by cauterizing the skin over and around it. The ligature should be kept on if the patient can bear it, even after constitutional symptoms have become severe, as it must delay the rapidity of the entrance of the poison into the general circulation. The indications for constitutional treatment arc active dif- fusible and alcoholic stimulants. Aromatic spirits of ammonia, whis- key, brandy, camphor, etc. are in order, but the overwhelming of tlie system with whiskey or alcohol, in obedience to the ])opular fallacy that to get a man drunk will cure him, has undoubtedly cost many lives from the whiskey. Patients are usually greatly excited, and tlicrcfore can tolerate large quantities of stimidants \\ithout intoxication, but if a man be intoxicated he is in a less favorable condition to eliminate the poison. So long as the heart's action is feeble and the pulse intermittent, stimu- lants and digitalis and strychnine, Avith perhaps nitro-glycerin, may be given freely. The cautious statement of Drs. Mitchell and Reichcrt that " potassic permanganate, ferric chloride in the form of the liquor or tincture, and tincture of iodine seem to be the most active and promising of the gen- erally available local antidotes," is sufficient answer to the vaunted claims of all sorts of nostrums as antidotes. Death comes, according to the observations of these most capable oliservers, " through paralysis of the respiratory centres, paralysis of the heart, hemorrhages in the medulla, or possibly through the inability of the profoundly altered red corpuscles to perform their functions. There can be no question, however, that the respiratory centres are the j)arts of the system most vulnei-able to venom, and that death is commonly due to their paralysis." ' " The outlook, then, for an antidote for venom which may be available after the absorption of the poison lies clearly in the direction of a physiological antagonist, or, in other words, of a substance which will oppose the action of the venom on the most vulnerable parts of the system. The activities of the venoms are, however, manifested in such divers ways, and so profoundly and rapidly, that it does not seem probable that we shall ever discover an agent which shall be capable at the same time of acting efficiently in counteracting all the terrible ener- gies of these poisons."

The constitutional disturbance which occurs during the healing of a wound is known as traumatic fever. Traumatic fever may be divided into two principal varieties — primary wound-fever and secondary wound-fever. Primary wound-fever may be also subdivided into two varieties — aseptic fever and septic or surgical fever. Aseptic fever is a febrile disturbance which occurs in woiuid-healing by first intention. In this form of healing the syuiptoms of local iuflam- mation are absent, and it was supposed in the early days of antiseptic surgery that sucli wounds would not be accompanied by fever. It w^as found, however, that the fever-ciu've often rose to a considerable height. In tins respect the conditions differ from those seen in surgical fever, where the constitutional disturbance keeps pace with the varying con- ditions of the inflammation in the wound. The cause of tliis rise of temperature was at first not fully under- stood, but experiments on anunals have shown that the absorption of fibrin-fermeut is often accompanied by serious symptoms. Fibrin is formed l)y the union of two filirin-generators, fibi'inogen and para- glolmlin, with the co-operatiou of fibrin-ferment. Fibrinogen is fotnid in the blood-plasma, wliile the fibrin-ferment and the paragloliulin are for the most part found in the white blood-corpuscles. If the fibrin- ferment is introduced experimentally into the circulation, extensive coagulation of the blood will be the result, and the death of the animal speedily eusues. During the process of healing by first intention a certain amount of fibi-in-ferment is absorbed from tlic extravasated blood, and also otiier substances which are found in the exudation which accompanies the inflammatory process. In a large wound healing l)y first intention we find not only extrav- asated blood and exuded serum, but minute fragments of tissue wliich have been separated from the surface of the wound during the opera- tion, and are subsequently disintegrated and absorbed. These materials when absorbed exert a pyrogenic action upon the system. Their close relationship to living substances, however, renders them but slightly injurious, and they produce in consequence only a mild type of fever. 415 416 TRAUMATIC FEVER, ERYSIPELAS, AND TETANUS Tho symptoms of aseptic fever arc few in nunibcr. The patient experiences no sense of discomfort, such as is observed in other forms of fever. The skin is not so hot or dry, tiie urine is not diminislied, and there is far less loss of weight tiian in septic fever. The thermom- eter, however, shows that there is a I'isc of temperature of from one to tliree degrees, and tiicre is also a corresponding increase in the pulse-rate, which continues so long as any absorption is taking place from the inte- rior of the wound. The patient is, however, unconscious of fever, and is often able to move aliout the room witiiout discomfort. This form of fever lasts usually from one to five days, or may continue longer when hemorrlingc has taken place and a considerable amount uf blood has to be absorbed. Fever of tiiis type is seen in cases of simple fracture and in large wounds healing by first intention, in cases of luematoma, and in contused wounds where there has been considerable iicmorrhage. Sejitie or surf/icd/ fever is observed in wounds liealing witii more or less septic inlliunmation, such as are seen following accidents or in cases M'here the j)rinciples of antiseptic surgery have not been observed. In such cases, although the wound may unite in the larger part of its extent, there is a great amount of redness and swelling and the other symptoms of local inflammation. A considerable discharge will take place from any ojien jioint in the wound, and perhajis also from the openings around the stitches, and in a few days a more or less extensive supjjuration may take place, although in fortunate cases a great portion of the wound may be healed before the formation of pus has taken place. These active changes in the wound were formerly supposed to be symptoms of the brisk reaction in the wound, and were thought essential to the pi'ocess of repair. We now know that they are due to sepsis. The constitutional symptoms are corresjjondingly severe in these cases, and keep pace pretty accurately with the amount of inflammation which occurs in the wound. As an ordinary result of an operation or accident there is a certain amount of shock, the temperature falls below the normal, the skin is cold and clammy, and the pulse weak. The following day reaction occurs : the pulse and tcmperatiu-e rise, the skin becomes hot and dry, the tongue coated, and the patient suffers from considerable thirst and restlessness. On the evening of the second day the tempei'ature is still higher ; there is great discomfort, and the patient may also suffer from pain owing to the swelling of the wound. On this account sleep is dif- ficult ; the patient may not only suffer from insomnia, but nervous symptoms will be present, and in severe cases often dclirimu. The tem- perature drops slightly c\-cry morning, to rise still higlier in the evening. With the subsidence of the local inflammation the temperature also falls, and with the discharge of pus from the wound the fall may be quite rapid, and there will be at the same time relief to all the other symptoms of inflanunation. Traumatic fever usually lasts about a week, at which time, if no extensive suppuration has occurred, the temperature will be found to have reached the normal line. The cause of this form of fever is found to be the presence of bac- teria in the retained secretions of the wound. A limited number of micro-organisms find their way into tlie circulation from this source. TRAUMATIC FEVER. 417 The decomposition which they have set up in the retained fluid liberates a certain number of cliemieal substances which are also absorbed. The ptomaines and toxiucs thus introcUiced into the circulation exert a pyro- genetic action. It is probable that no one form of virus habitually causes traumatic fever, but that various substances have this effect. For- tunately, they do not exert a very poisonous action upon the tissues, but sutficient to cause considerable fever and discomfort io the patient. AVith the advent of suppuration these substances and organisms are carried away in the discharge from the wound, and, as those wliicli have already obtained an entrance into the circulation are speedily eliminated, the fever then disappears. Sccniid/irt/ trdioid-fcrfr, or suppurative fever, occurs when pus has formed which has not an opjxn'tunity to escape from the wound, and in consequence chemical substances formed in the pus by the bacteria are absorbed into the system. In this case the fever-curve, instead of falling to the normal line at the end of the first week of the healing process, rises again, and this rise in some cases may be accompanied by a chill. There is usually a marked morning remission, with a subsccpient rise of temperature every evening, which becomes more exaggerated as the sup- purative process extends. Marked types of this form of fever are seen in the su})purati()n which follows compound fractures and in operative wounds in which the flow of pus has been obstructed. The pus conse- quently burrows in the surrounding connective tissue. In these cases the symptoms which accom|)any the rise of temperature are similar to those which we have just desi'ribed. The patient suffers from dryness of the skin and coated tongue, headache, malaise, and in severe cases a mild delirium. When a free evacuation of the pus has been obtained the symptoms disappear and the temperature falls to the normal line. In unfavorable cases, where the jius has burrowed in various directions, chronic suppuration is established, and the fever now resumes the cha- racteristic remittent type. In the morning the tem])erature is normal or even subnormal, but in the evening there is a sharp rise, varying from one to six degrees. Unless the progress of the suppuration is checked there is a marked change in the appearance of the patient. .The loss of flesh is often very great, prostration occurs with the evening rise of tem- perature, the characteristic hectic flush is established, and with the tall during tlic night there is the jirofuse perspiration or night-sweat which is so characteristic of this condition. Diarrluea may also set in to aggra- vate the patient's condition. In fatal cases emaciation becomes extreme, the joints are unusually prominent, and bed-sores appear. The patient finally becomes exhausted and succumbs to the disease. Tlie })rincipal change found at the post-mortem examination is amyloid degeneration, which occurs in the spleen, liver, intestines, and kidneys. This is supposed to be caused by the constant presence of alkaline salts produced by suppuration. This type of fever has been sometimes confounded with pyiemia, and is called by some authors pyajmia simplex, in contrast with the multiple or metastatic form of pyiemia. It should not, however, be confounded with this affection. Treatment. — Aseptic fever usually requires little or no interference on the part of the surgeon. Persistence in the rise of temperature indi- cates the presence of an unusual amount of blood collected beneath the Vol. I.— 27 418 TRAUMATIC FEVER, ERYSIPELAS, AND TETANUS. lips of the wouikI. In such cases tlio hciding ]>rocess maybe hastened by the introduction of the probe or of a temporary drain to allow the escape of the blood-serum, whieli prevents tlie accurate coajitation of the surfaces of tiie wound. In surgical fever a careful watcii nnist l)e kept as to tiie condition of the wound, in order that, if su|)puration is established, pro- vision may be made ibr the proper evacuation of jnis. The removal of one or more stitches or the introduction of the drainage-tube may be sufficient for this purpose. If, liowever, tiie general appearance of the wound is threatening, it should be freely opened, a thorough disinfec- tion of its surfaces siiould lie effected, and provision made for the free discharge of tiie products of dccomj)osition. When it is clear that su]ipurative fever is cstablislied, the pus which is causing this disturliance should be followed relentlessly in all direc- tions. In localized collections of pus a moderate opening is often suf- ficient to check the furtiier progress of 'sujipuration, but wlicn pus begins to ijurrow free incision shoukl be made and the walls of tiie wound should be curetted, so as to remove, if possible, all jiyogenic organisms. When it is impossible to lay open the wound in its entire extent, a connter-opening should be made at some prominent point, througii which drainage-tubes leading in various directions may be introduced. The wound should lie thoroughly flusiied with some antisejitic agent suf- ficiently weak to avoid poisoning by absorption. For this purpose car- bolic acid in tiie strengtii of 1 : 200 may be nsed, or corrosive sublimate in a solution of the strength of 1 : 5000. The penetrating power of the corrosive is not so great in this case as that of carbolic acid, as the latter is able to incorporate itself more completely with greasy substances. Sulpho-naphthol, in a strength of 1 : 260, or creolin may be used. Tiie disinfection of suppurating wounds may also be eft'ectually accomplished by the application of'peroxide of liydrogen. The drainage may consist of rubber tubing or of strands of iodoform or sterilized gauze. The strength of the patient should be carefully watched. Alcoholic stimulation is of great importance in these cases. The patient will often be able to bear a large amount of alcohol witliout discomfort. Good hygienic surroundings should be secured, and tlie patient may often be placed in the open air for many honrs at a time, even in cold weather, with benefit during the process of chronic suppuration. n. Erysipelas. Erysipelas is an acute inflammation of tiie skin spreading along its upper layers and occasionally penetrating to the deeper tissues. It may involve mucous membranes. It is accompanied by fever. It lias a tend- ency to more or less complete recovery, but it may recur. The name is derived from ipu3p6c, red, and vtirAa, skin. Although the disease was known to the ancients, reliable reports previous to the epidemic described in France in 1750 are rare. Epi- demics are described as occurring in Great Britain in 1777 and 1780, and also in 1821 and 1832. A very extensive epidemic of erysipelas occurred in this country in 1842, and the disease is described as prevailing in vari- ous parts of Europe in the following year. The accounts of this last ERYSIPELAS. 419 epidemic are clear, and show the disease to have existed in a far more malignant type than that seen to-day. In fact, epidemics of this disease are at the present time practically unknown in civilized communities. The disease often assumed at that time the phlegmonous type, and worked its way deeply between the muscles of the trunk, and some- times involved a whole extremity. In New England it spread from village to village and many lives were sacrificed. The streptococcus of erysipelas was first described by Fehlciscn.' The cocci grow in serpentine chains. They are small, varying from 0.3 fi to 0.4 p in diameter ; they are, however, somewhat larger than the strepto- coccus pyogenes. The culture of the coccus upon gelatin develops slowly, and appears as a very delicate grayish-white film, not unlike that of the streptococcus. The question of the identity of these organisms is still a mooted one, although the feeling at present tends to the belief that the streptococcus of erysipelas is a specific organism. It has been suggested by some observers that in the suppurati\'e forms of erysipelas pus is developed by the action of the pyogenic cocci ; others believe that the streptococcus of erysipelas when developing in the subcutaneous tissue has a more virulent local action and may become pyogenic. The cocci are found in the capillary h'mphatics of the skin chiefly, but are also occasionally seen in the capillary blood-vessels and small veins. The growtli of tiic organism is most active near the red margin of the er^'sipclatous l)lush. The virus may lie transmitted to different parts of the body through the circulation, and the constitutional dis- tui'bance is probabh' due to the presence of the cocci or their ptomaines in the circulating blood. The virus gains entrance to the body almost invariably through a wound : even in the so-called cases of idiopathic erysipelas the cocci find their way through some minute abrasion in the skin. The clinical evidence of the contagiousness of erysipelas is abundant. Stille^ reports the following striking example: In 1852 a man arrived in Platte county, INIissouri, suffering from erysipelas of the face. He was nursed by a farmer, who himself fell ill of the disease. A second farmer, who assisted in nursing these two patients, was seized by the disease, and subsequently six other persons, who helped to nurse in their turn, were attacked. No other case occurred in the neighborhood. The occurrence of erysipelas following vaccination was so frequent in Boston in the winter and spring of 1850 that vaccination was temporarily abandoned. The disease was probably not conveyed in the vaccine virus, but by an unclean instrument. The close relationship of ervsi]ielas and j)uerperal fever has been recognized by many authorities, and the impropriety of attending a case of confinement after handling erysipelas is now well understood. Trousseau describes an epidemic of puerperal fever which rendered the closing of a hospital necessary. In the hospitals to which pregnant women were transferred er^-sipclas liroke out among the surgical cases in many instances. Exposure to cold was for a long time supposed to be a cause of ery- ' Die Etiologk des Erysipels, Berlin, 1883.

The spring and late winter months are regarded by many surgeons as a par- ticularly favorable season for the development of the disease. Erysipelas is comparatively rare in childhood, although it is seen in badly-arranged lying-in hospitals as erysipelas iwoiiatornm when puer- peral fever prevails. It does not occur so often in old age as in the prime of life. Certain constitutional conditions, as alcoholism and diabetes, are supposed to act as predisposing causes, and some individuals frequently attacked by erysipelas are supposed to have a predisposition to the disease. Symptoms. — The disease usually manifests itself at first by a chill, with fever and symptoms of gastric disturbances. The tongue is coated, and there is often a sense of oppression at the epigastrium, and some enlargement of the lymphatic glands belonging to the vessels leading from the jwint of infection. An examination of the wound does not, however, show any origin, as yet, of an infective inflammation. Occa- sionally the constitutional disturbance is so slight as to pass unnoticed, and the first sign of any disorder is in the Mound itself. In twenty-four to forty-eight hours from the time of the beginning of the attack there is an itchmg or inirning sensation in the vicinity of the wound and the skin becomes tender to the touch. There is at first a blush on the skin in the vicinity of the wound, ^diich gradually deepens in tint and has a more dusky hue than the rose color t)f hj^pertemia. There is a yellowish tinge mingled with the red, and this becomes more evident upon pres- sure, which shows a yellow stain to the diseased part during the moment in which the blood is pressed aside. The swollen tissues become tense and hard and do not pit on pressure. The swelling is most evident about the eyelids, where the skin lies loose, and also about the genitals. As the swelling and infiltration of the part increase, small vesicles form which may at times attain considerable size. When the local inflanmiation is fully developed it shows a tendency to spread, and the outline of the diseased part is usually well marked and is often quite irregular. The inflammation runs its course at any one particular point in three or four days, but in the mean time it has invaded new regions, and this process may go on for a considerable period of time, and the surfaces involved in the inflammation are often quite extensive {erysipelas mic/raris). It may even revisit jtarts which have already been infected and are convalescent from the original attack. The tendency to recur is a marked feature of the disease, but so also is the tendency to recovery, and it is rare that the attack lasts longer than two weeks. As the inflammation subsides there is an abundant desqua- mation, and, as in the superficial form of erysipelas there is no sup- puration, there is a complete return to the normal condition of the skin. The condition of the wound during an attack of erysijielas varies greatly. In the early stages of the healing process a wound the edges of which are in apposition may reopen, the interior presenting a slough- ing aspect, and in the severer forms extensive destruction of tissue may take place, which may involve vessels of considerable size, producing secondary hemorrhage. At other times, particularly when the disease ERYSIPELAS. 421 has attacked a wound in tlie stage of granulation, there appears to be little local disturbance, and the healing process may go on even more rapidly tlian l)ef<»rc. The constitutional symptoms correspond pretty closely with the amount of local inflammation in the majority of cases. Accompanying the gastric disturbance there are usually a chill and a rapid rise of tem- perature, follo\vcd liy a slight fall on the following morning. The sub- sequent changes of temperature are most erratic, corresponding to the amoiuit of inflammation — as a rule, however, showing the remittent The tongue is heavily coated, and there may be vomiting and diar- rlicea. In the most severe cases there may be delirium, and the disease shows a tendency to assume a tyjihoid type. The variety of erj'sipelas known as facial cnji^ipelas is often called idiopathic, as it does not appear to take its origin from a wound. The virus in these cases probably obtains an entrance through some small wound, abrasion, or pustule in the skin. The disease is first observed on the nose or near one of the lachrymal ducts, and spreads slowly along the lines of the cheek beneath the orbit in the direction of the ear. As it approaches the temple it may rise to tlie forehead and invade the scalp, or it may turn downward to invade tlie neck. The chin is rarely involved. In mild forms the disease gradually fades away as it reaches the ear, and the amount of constitutional disturbance is in such cases very slight. In the severer types of facial erysipelas the amount of swelling is usually very great ; the eyelids become oedematous, and the eyes are closed, the disiigurenient becoming at times so great that the patient is unrecognizable. The color of the skin is scarlet, and tlie sur- face is covered with vesicles wliich here and there run together, forming bullffi of considerable size. Tlie lymphatic glands in front of and behind the ears are enlarged, and when the scalp is invaded the glands in the back of the neck are involved. In the severer forms of facial erysipe- las, particularly if the scalp be involved, there is delirium, and a slight tendency to tlelirium is noticed even in mild forms of the disease. This appears to be caused either by reflex nerve-irritation, or by a vasomotor disturbance causing hypersemia of the meninges, or by an extension of the septic processes through the orbit to the membranes of the brain. Fortunately, the latter complication is of rare occurrence, and with the sul;)sidence of the inflammation of the skin the cerebral symptoms usually disappear. The tendency of the inflannnation to involve the deeper tissues of the orbit is characteristic of the graver forms of erysipelas, and blind- ness is sometimes caused by the extension of the septic process to the eye itself, jiroducing either a panophthalmitis or degenerati\'c changes in the optic nerve. A rare complication is the formation of an orbital abscess. The duration of facial erysipelas, like that of other forms, is cpiite variable. In mild cases the disease rarely lasts beyond one week ; in the severer types, or in cachectic individuals, the inflannnation may last several weeks before it entirely disa])pears. Phleojioxous Erysipelas. — When the disease spreads to the deeper tissues the virus appears to assume greater activity. The amount 422 TRAUMATIC FliVER, ERYSIPELAS, AND TETANUS. of swelling is in sucli cases much greater, and tlie skin 1)eeomes tense and hard. Vesicles form, wliieh are sometimes filled with bloody fluid, and the surrounding parts are swollen and (edematous. The eonstitu- tioual disturbance is great. Chills frequently occur, and the fever assumes a typhoid character. As pus forms in the subcutaneous tissue, the skin above loses its tension, and becomes boggy and more or less movable on the parts below. A free incision gives vent to a sanious ])us, mingled with shreds of sloughing tissue which have been likened to masses of wet blotting-paper. The suppurative process gen- erally extends for some distance beneath the surface, and several incis- ions are usually necessary to drain the parts properly. The muscles may be separated from one another, and even joints may be involved in the septic process. In some cases gangrene of the skin may occur, and on such occasions the skin Ijecomes a dusky-red in color and large bnlhe form filled with bloody serum. It is principally in old and feeble iiulividuals that such a complication occurs. It is known as gangrenous erysipelas. The con- stitutional disturbance is in such cases very great, and many patients will succumb with symptoms of pysemia or of septictemia. EEYSIPELA.S Neonatorum is most freciuently seen in hospital prac- tice. It takes its origin from the granulating surface of the stump of the umbilical cord. The slight blush about the navel is at first accom- panied by but little fever. As the disease progresses the septic process may extend over the abdomen and involve the genitals and thighs. There is then high fever, and the child cries and is restless. In the later stages collapse supervenes, and the child dies on from the sixth to the tenth day of the disease. Gangrene is an occasional complication of this form of erysipelas. The disease may spread along the hypogas- tric arteries or the umbilical vein, and peritonitis may occasionally occur in consequence. Erysipelas of Mucous Membranes occasionally occurs. When the pharynx is involved the color of the throat is a dark red, and there is a tendency to dyspnoea and difliculty in deglutition. There is also a marked enlargement of the cervical glands. The thorax may become the seat of diphtheritic inflammation, and suppuration may take place in the submucous tissues. The mouth may also be involved in the inflammatory process, and the tongue then becomes greatly swollen and congested, giving rise to that variety of disease known as " black tongue." The disease is said to extend along the air-passages to the lungs, giv- ing rise, perhaps, to oedema of the glottis or to septic pneumonia or jmeu- monia migrans. Such forms of erysipelas arc extremely rare at the present time, and were observed principally in those malignant epidemics which have already been mentioned. Erysipelas may occasionally extend from the vulva to the vagina and from the nates into the rectum. Pathological Anatomy. — An examination of the principal seat of the disease — the skin — shows that there is a considerable exudation in the rete mucosum and in the upper layers. The superficial net- work of lymphatics is filled with streptococci, which are most numerous near the margin of the inflammation. There is a considerable hyper- ERYSIPELAS. 423 jemia of the blood-vessels of the affected part, and the surrounding tissues are infiltrated with leucocytes. In some types of erysipelas minute abscesses, which during life have escaped observation, are often found in the cutis. The changes observed in the circulating blood are supposed to be due to the micrococci, although they are rarely found there in large numbers. The red corpuscles are found to assume a erenated appearance, and dis- solve and run togetiier readily. The white corijuscles are usually in- creased in number. Endcjcarditis is occasionally observed. Tiie gastric symptoms appear to be due to the condition of the system, rather tiian to any local change. Catarriial ulcers are, however, sometimes found in the small intestines. The brain and membranes are hyperjemic and cedematous in tiie severe forms of facial erysipelas. Suppurative men- ingitis is, however, extremely rare. Enlargement of the spleen is often found, and there is frequently some cloudy swelling in the kidneys. Tlie }>arotid gland may also become inflamed. The curafire influence of erysipelas (erysipele salutaire) has long been recognized. Wounds iieal more rapidly, cin-onic inflammations of the skin disappear, and old ulcers begin to granulate. Tilmans reports several eases of sarcoma of the face and neck which either disappeared after an attack of erysijielas or were greatly reduced in size.' In one case the patient died of the erysi})elas, and the cells of the tumor were found to have undergone extensive fatty degeneration. Fehleisen, in order to demonstrate the specific character of tiie streptococcus of ery- sipelas, inoculated man on several occ^asions witii success, the human inoculations being used also for tiie purpose of testing the curative clia- racter of tiie virus. A death luu'ing occurred in the hands of uuitators of tills method, the experiments were abandoned. Recently, Coley ^ has experimented with the virus, and has collected 38 cases of malignant disease in wliicli erysipelas had occurred either by accident or intent. There were 17 cases of carcinoma, of which 3 were permanently cured, and of 17 cases of sarcoma 7 were well and free from recurrence from one to seven years after the attack of erysipelas. As in some cases when the pure culture has been used death has followed the inoculation in the hands of other surgeons, Coley has substituted the toxic ]iroduets of tiie erysijielas coccus for tiie pure culture. Tiiey are thus obtained : The strejitococeus is planted in bouillon culture and allowed to grow for six weeks, wlieii tlie bouillon is filtered. The fil- tered material contains no bacteria, but is rich in toxic products. Spronck's method of preparation is as follows:* The streptococcus is planted in two large flasks of equal size nearly filled with bouillon. Tile cotton plugs are covered witli a layer of paraffin. The flasks are sul)jccted to a temperature of from 33° to 35° C. for fifteen days. After the purity of the culture has lieen verified, the contents of one of the flasks, to which 5 per cent, glycerin lias been added, is subjected for three hours to a current of steam at 100° C, and is finally reduced to one-tenth its volume by boiling. After cooling this liquid is added to the contents of the other flask and the mixture is filtered.

Prognosis. — Acute tetanus is one of the most fatal of diseases, but in cln-onic tetanus the percentage of mortality is very much less. The longer, therefore, the patient lives, the greater are his chances of recov- ery. Yandell in a study of 415 cases noted a marked falling off in the number (jf deaths on the fifth day, after which period the mortality steadily diminished. Tetanus occurring in military surgery appears to be unusually fatal. In the Surgical History of the War of the RcbcUion 505 cases are recorded, the mortality being 89.3 per cent. Of Yandell's cases, which wei'e col- lected from various soui-ces, 213 recovered and 182 died. The date of the first appearance of the disease is a sign of prognostic value. Yan- dell found that where the symptoms were delayed until the fourteenth day from the time of injury the recoveries exceeded the deaths. The gravity of the wound does not appear to have any influence upon the severity of the disease. In tropical climates the disease is much more fiital than in the temperate zones. Treatment. — In estimating the value of any particular drug it is important to remember the statement of Yandell, that when tetanus continues fourteen days recovery is the rule and death the exception, apparently inde])cndent of treatment. Yandell places chloroform at the head of the list of drugs in cases of acute tetanus. The weight of evidence appears to be in favor of the sedative action of this drug upon the nervous system. It may be administered by inhalation, eitlier to the point of anajsthesia or a napkin may be placed upon the chest of the patient, who is thus exposed to the influence of the drug. Its action is not, however, so enduring as that of chloral. Chloral seems to be most efficacious in chronic tetanus. It appears to act by diminishing reflex excitability in the nerve-centres ; it relieves pain and prevents spreading of the muscular spasm and the recurrence of the convulsions. It may be continued for one or two weeks at a time, and in this way an almost permanent sleep may be maintained, which paves the way to convalescence. In doses of 100 to 200 grains a day it will relieve muscular spasm in acute tetanus, but it does not appear to have any appreciable effect upon the mortality. Opium, when used, must be given in large doses to control the spasm, and the digestive disturbance caused by the drug is a contraindication to its use. Bromide of potassium can be given in connection with chloral, or in the convalescent stage as a substitute for that drug, but it is altogether TETANUS. 431 too mild a remedy to produce an appreciable effect in the more active stages of the disease. Calabar bean, or its active principle, when given in small doses, I'elieves the muscular contraction ; the jaws relax, and the head reposes quietly upon tlie jjillow. If given in large doses, the spasms appear to be greatly aggravated. Poncet explains the favorable action of the drug by its eifect upon the conductibility of the motor nerves by which the muscular system is, as it were, isolated from the nerve-centres. He prefers to give it by the mouth rather than In' subcutaneous injectii)n, as the dose can be more carefully regulated and the action of the drug observed by tills method. From | to 1 grain of the extract may be given by the mouth every four hours, and 15 to 20 drops of a 1 per cent, solution may be injected subcutaneously. The statistics of Knecht give a mortality of 45 per cent, in 60 cases in which this drug was used. Warm baths and dia}ilioretics have been used extensively in the treatment of tetanus, doubtless in imitation of Nature's method of giv- ing rebel", as diajihoresis is a frequent symjitom of the disease. Vapor baths are probably the most efficacious way of carrying out this treat- ment, as they are less likely to disturb the patient and thus aggravate symptoms. In no disease should the comfort of the patient be so care- fully studied, and every eifort should lie made to avoid disturbance or irritation of any kind. The value of skilled nursing is shown nowhere to greater advantage tlian in tliis disease. Due attention siiould be given to the wound, and an eifort shoidd be made thoroughly to disinfect it. The wound should consequently be laid open, and its surfaces not only exposed to the action of oxygen, but to powerful antiseptics, as in this way the amount of the virus may possibly be diminished. Punctured wounds should be opened sufficiently to admit of thorough disinfection. It is possible that the present asep- tic method may permit the early closing erf a punctured wound, and thus favor the development of the tetanus bacilli in the deeper layers of the wounded part. The old-fashioned poultice by setting up suppu- ration ftvvored a discharge of all poisonous material. In some cases the scar is red, tender, and swollen. Such scars should be excised, and in all cases it is advisidde to open and explore the cicatrix, as in some instances particles of dirt have been removed with the cicatricial tissue. Experiments u])on animals have shown that immunity can be obtained by inoculations with minute doses of the poison or with a filtrate Avhich has been exposed to a temjjcrature sufficient to destroy its activity (Kita- sato). Immunity was also obtained for a certain time by inoculating animals with the filtrate from the culture of the tetanus bacillus, and subsequently by inoculating them at the same point with a solution of terchloride of iodine. It was further found that the blood-serum of an immune animal when injected into another animal protected it from the effects of the inoculation with the tetanus bacillus, and that inoculated animals in whom the tetanic symptoms had already made their appearance were preserved from death by the injection of the blood-serum of an immune animal (yternberg). Tizzoni and Cattani gave the name " tetanus antitoxine " to the substance existing in the blood of an immune animal which produced these results. Behring found that the more intensely the animal was inoculated to render it 432 TRAUMATIC FEVER, ERYSIPELAS, AND TETANUS immune, and the longer it liad remained inoculated, just so much less of its serum was required to cause iiunuiiiity in another animal. A more powerful dose was, however, required for therapeutic purposes to check tetanus which had already made its appearance. These interesting experiments have led, as yet, to a limited employ- ment only of the antitoxine in the treatment of tetanus in man. A number of successful cases have been reported, Init the treatment seems to have been employed almost invariably in chronic tetanus. In a case reported by Rotter treatment was not begun until the fourteenth day of the disease : 36 grammes of blood-serum from an immunized horse, with 5 per cent, of carbolic acid, were injected into the back. The injections were continued for five days, and the patient recovered, the symptoms rapidly yielding to the treatment. RABIES; HYDROPHOBIA; LYSSA. By HERMANN M. BIGGS, M. D. Rabies is an acute infectious disease occurring in many species of animals and in man. It is transmitted solely by inoculation from an infected animal, usually through a bite, and is characterized by a long period of incubation, paroxysmal convulsions, great mental disturljance and excitement, fever, often l)y general motor paralysis, and terminates almost invariably in death. Wiien rallies occurs in man it is connnonly called hydrophobia, because of peculiar spasms of the muscles of the throat whi(^li follow any attempts at deglutition, or which may occur even at the sight of water or food. These are extremely ]iainful and produce great terror in the patient, and Jienee the name "hydrophobia." Rabies ix Animals. — Rabies may occur in many species of animals besides dogs, especially in those of the canine genus, wolves and foxes, and in skiudvs. Cats are sometimes aifected, although less commonly than dogs. It may also be transmitted to herbivora — to horses, cattle, sheep, goats, rabbits, pigs, guinea-pigs — and less readily to other species of animals, either ex])eriuientally In' inoculation or through the bites of rabid dogs. .Vdami has reported a very extensive epidemic of ral)ies which occurred in 1885 among the deer in Richmond Park in England and afterward in the park of the marquis of Bristol. Rabies is rarely transmitted from other animals than those of the canine genus. In dogs the symjitonis of rabies vary somewhat, but the first real symptom, usually not noticed, is a rise in temperature. This is fol- lowed by dnlness, with an indisposition to move; later, the animal becomes shy, suspicious, restless, and irrital)le, often snapping at any- thing which comes near. At tliis period he frequently leaves home if he is not confined, and may make long excursions, sna])ping'at everv- tiiing in his way, and particularly attacking other dogs or animals. Tln-oughout this early period there is a depraved appetite, the animal rejecting tiie usual food and devouring hay, cloth, wood, coal, gravel, fiecal matter, or even its own hair or tail. This symptom is important and rather characteristic, although it is by no means pathognomonic, for frequently it may be seen in other diseases than rabies. Almost in\'ari- ably the bark is altered ; it is hoarse, unlike its usual tone, and ter- minates with a peculiar howl. In one variety of the disease in dogs there is intense, almost maniacal, excitement ; in another there is early paralysis of the muscles of the jaw (so that it hangs down and allows frothy saliva to escape from the mouth), followed by general motor paralysis. In all varieties there is commonly weakness of the muscles of deglutition : this interferes \vith swallowing, but at no time in the disease is there any fear of water. A rabid dog will often plunge his Vol. I.— 2S 433 434 BABIES; HYDBOPIIOBIA; LYSSA. nose and partially suhmergo his head in a disji of water or in rnnning water. There exists a popnlar and danujeroiis fallacy rejjardino tliis fear of water, wiiich is no doubt based on tiie name " hydro]iliol)ia." It is eoninionly believed by the laity that a dog cannot be rabid if he drinks or submerges his head in water. After a longer or shorter period, in all cases paralysis appears, and the dog staggers in attempts to walk, and often falls. Finaliv, tlie weakness in the legs becomes so marked tliat the animal is unal)le to stand, and dies completely paralyzed. A distinction has often been made between dumb or paralytic and furious rabies, but the difference is largely one of degree of excitement, which may depend upon the conditions surrounding the animal in the early part, and the rapidity of the course, of the disease. In every case, ultimately, there is paralysis more or less complete. A change in the disposition oi' an animal, siiy- ness, restlessni^s, illusions of sight and heai'ing (shown by sna]iping at invisible objects in .the air, elevation of the ears, an attentive j)osition, due to the hearing of sounds which do not exist), perversion of appe- tite, wandering from home, and similar modifications of the nsual apj)earancc, action, and manner, are all symptoms suggestive of the dis- ease in the early stage. It is an important point to determine when a raljid animal can transmit the disease. Experimental observations have shown that there is commonly an elevation of temjierature in dogs before any other symptoms of the disease appear, and at this time, and even per- haps for twenty-four or forty-eiglit hours or more before tlie elevation of temjK'ratui-e, the l)ite of tlie animal may be virulent. In this way are explained the eases of rabies which have been reported as resulting from the bites of animals ajiparently in perfect health, and to this, no doubt, is due the belief which formerly existed that nnder certain con- ditions the bites of animals might produce hydrophobia wlien they them- selves \\ere not affected by the disease. Kabies in dogs almost invariably terminates fatally. There are, however, some very rare cases in which recovery occurs. The duration of the disease is variable, sometimes death occurring in twenty-four or thirty-six hours, while in other cases it is postponed for seven, or even very rarely for nine or ten, days, \yhen a person has been bitten by a dog, whether suspected of being rabid or not, instead of destroying the dog innnediately, as is too frequently done, the animal should be placed in confinement and kt'jit under observation for several weeks if necessary, so that it may be witli certainty determined whether the dog was or was not rabid. If the dog is destroyed, it is of course impossible to determine whether it was ral)id or not, except by the inoculation of other animals, by the subdural method of Pasteur, witli the medulla or spinal cord. As will lie seen later, however, a jimliable diagnosis can frequently be based upon the autopsy-findings and the microscopical examination of certain portions of tlie brain. In the rabbit the sym])toms, as produced by inoculation, commonly resemble those of dumb or paralytic rabies as it occurs in dogs. They are not unlike those found in the human being in acute ascending paralysis, and consist in dulness with some pyrexia, followed by weak- ness in the hind legs, which gradually increases and extends for\vard DISTRIBVTIOX AND FREQUENCY.— ETIOLOGY. 435 until a complete jicneml paralysis results. Tiie animal lies tlicn upon its side, with dittieult and labored respiration and complete motor paralysis. The period of incubation in animals is exceedingly variable, espe- cially when the disease is produced by subcutaneous inoculation. It varies from seven or eight days to a month or more. In the subdural method of inoculation of Pasteur, after the virus has been passed through a series of rabbits the period of incubation in tliese animals l)ecomes per- manently shortened to about seven days, and remains uniform at this point when the inoculations are made by this method. Distribution and Frequency. — For a long time it was assumed that ral)ies \vas confined to, cir was chiefly found in, temperate regions. Furtlier observation lias shown, however, that it occurs in all parts of the world, excei)ting perliaps in Australia, New Zealand, and one or two other isolated localities wliere it apparently has not yet been introduced. The frequency with which the disease occurs varies greatly. Like other epizootic diseases, it often appears in epidemic form. It can be entirely eradicated by the efficient enforcement of a law ]>roviding for the muzzling of dogs. Rabies has bec(jme practically an unknown disease in many parts of Germany ami some other Eurojiean countries as the result of properly enforced laws regarding nuizzling. Under all conditions rabies is a comparatively rare disease in man. Boudin, in a communication to the Frencii Academy in 1863, gave the number of deaths from iivdrop]iol)ia in Prussia, from 1854 to 1858, as 196 ; in Belgium, from 1856 to 1860, as 26 ; in England, from 1853 to 1857, as 100 ; in Scotland, from 1855 to 1S63, 10 ; in Sweden, from 1856 to 1860, as 42. In Ireland the nmnber of deaths for ten years ending in 1879 was 21 ; in London, according to the Registrar-General's return, thei'e were no cases from 1856 to 1862, 2 in 1863, none in 1864, 9 in 1865, 6 in 1866, 2 in 1879, 3 in 1880, 5 in 1881, 4 in 1882, 8 in 1883, 9 in 1884, and 27 in 1885. Muzzling was enforced in 1886, and the number suddcidy fell to !), all of which occurred in the early part of the year. In 1887 and ISSS there was not a single death reported. The number of cases occurring annually in this country has been very small, although the actual number cannot be determined. In New York City, during tiie ten years ending in 1891, there were in all 9 deaths reported to tlie Health Department as being due to rallies. In 1887 in the wliole of tiie German Empire there were only 4 deaths from rabies. In France rabies is apparently more prevalent, although, according to the reports of Tardieu and Brouardel for tiie years 1850 to 1872, there were in all 685 deaths, an average of a little less than 40 yearly. Tardieu says of his reports that nearly all departments replied to his inf|uiries, and Brouardel, tliat alxmt two-thirds were included in liis. Since tlie pul)lic announcement of the discoveries of Pasteur regarding the preventive treatment of rabies, however, apparently the numlier of cases of infec- tion has largely increased, if we are to assume that all those inocadated iiad really been bitten l)y rabid dogs, for from 1200 to 2000 French- men liave been inoculated each year. Etiology of Rabies. — Tliere is but one efficient cause of rabies, the introduction of a specific virus derived from a ral)id animal. Of the nature of this virus we have as yet no absolute knowledge, lint there 436 RABIES; HYDROPHOBIA; LYSSA. can be no I'easonable donbt, reasoning from analogy, tliat it is a niicro- organisni of some kind. Nnmerons other causes liave been commonly supposed to be efficient in the production of the disease. There are popular supei'stitions to the eii'ect that the bite of an angry dog or of one in rut may be followed by rabies, that the disease is especially prev- alent during the hot months of the year, and that certain breeds of dogs are particularly susceptible to rabies. These superstitions are not at all borne out by experience or statistics. Law (piotes statistics from Bouley showing that in the winter months among dogs there occurred 75i3 cases of rabies ; during the three spring montlis, 857 ; during the three sum- mer months, 788 ; and during the three autumn months, 696 ; which indicated that the largest number of cases occurred in the spring months, but tliat there was really little difference in the ntnnber of cases occurring in any season of the year. There are certain questions which arise in connection with the etiol- ogy of rabies which are of importance and interest. The virus undoubt- edly resides, particularly in dogs, in the saliva and salivary glands. The disease was long ago produced in dogs by ^lajendie by inoculating them with the saliva of hydro])h()l)ic patients and of rabid dogs. Pasteur has shown that the virus exists after death in the central nervous system, particularly the medulla or sj)inal cord, and also in the peripheral nerves, as well as in the salivary glands, and that the disease may be produced more certainly and with a more uniform period of incubation when inoculations are made beneath the dura mater after tre])hining the skull than when they are made by subcu- taneous injection of the virus. It is probable that the disease may be communicated from one human being to another, although no well- authenticated cases of this sort have been recorded. JMedical men and nurses who are in attendance on cases of hydrophobia always escape, although the saliva is often thrown upon the faces, hands, or clothing. The virus is, as a rule, rajiidly destroyed by decomposition, although one or two cases have been recorded where hydrophobia ajijiarently resulted from accidental inoculation at the post-mortem examination of cases of rabies. In a large majority of all cases in the human being the disease is contracted from the bite of a dog, in a very few cases from the bite of a cat, and occasionally, especially in Russia, from the bite of rabid wolves or foxes. Bites on uncovered jiarts of the body, as upon the face or hands, are f\ir more likely to be followed b}- the disease than if inflicted u])on jjortions covered with clothing, as in the latter case the virulent saliva is frequently entirely wiped off from the teeth. The dis- ease has l)een caused bv a rabid dog licking a scratch u]ion the hand, and apparently it has followed the scratch of a rabid cat, the animal's saliva having been probably thus introduced. There is absolutely no reason to suppose that the disease can ever result from the bite of any animal not suffering ft-om rabies. Undoubtedly, the cases in which this is supposed to have occurred have been either otherwise inoculated or have been infected by an animal apparently well, but in which the s3'mptoms had not yet appeared, as it has been shown that the saliva may be virulent for several days at least before the appearance of the disease. A large proportion of the cases occurring in the human being are in children, INCUBATIOX. 437 because tliev are more likely to be bitten, and becaose tliey are more frequently bitten on exposed parts of the body. In rare instances the disease has l)een transmitted to human beings and to other animals from rabid cattle, horses, sheep, etc. In these animals the saliva may be also virulent. The saliva from rabid animals will retain its virulence for a consider- able period after having been dried. Pasteur has shown that the spinal cords of ri'bid animals which have been dried lose their virulence at the end of about fourteen days. Exposure to comparatively low temj)era- tures also destroys the virulence of rabic virus ; that is, exposure for one hour to a temperature of 50° C. The direct rays of the sun and exposure to the action of 1 per cent, sublimate solution or 1 per cent, carbolic solution for three hours have the same cflFect. Byron has shown that the virulence may be preserved l)y immersing the rabic spinal cord in pure glycerin or by sealing up aseptic pieces of the spinal cord in test-tubes. The susceptibility of animals to the virus varies with the kind of tissue into which it is injected. Intravenous injections are not often followed by the disease. Injections into the muscular tissue are more freipientlv followed bv infection than injections into the subcutaneous tissue, and the apjjlication of the virus to divided nerve-filaments is generallv etficacious in ])roducing the disease. Divestin, Zagari, Pas- teur, and others have apparently shown that the virus extends from the seat of infection along the uerve-trunk to the spinal cord, and if the animals arc killed at the proper time the virus may be found in the nerves leading from the part infected when it is as yet absent in other parts of the nervous system. Tims in bites of the posterior extremities it is jn'cscnt in the lumbar cord when absent in the cervical region or medulla. It is apparently sometimes present in the pancreas and lach- rymal glands, and rarely in the secretion of the mammary glands ; but it is usually absent from the blood, liver, spleen, and kidneys. Incubation.— The incubation period of rabies in dogs varies widely. The shortest period is apparently six days, and the longest al)out eight months. In the majority of cases it varies between fourteen and thirty days. In horses, cats, sheep, and swine it is ordinarily from twenty to thirty days, but the period may be prolonged considerably beyond tliese limits. Bollinger says that in 60 per cent, of all cases in the human subject it is between eighteen and sixty days ; in 6 jier cent., between three and eighteen days; and in 34 ])er cent, the period is longer than sixty days. Cases have been recorded where the incubation has ap})ar- ently been greatly prolonged to from one to three or five years. These cases, however, are not well authenticated, and in well-observed cases the incubation rarely, if ever, is more than twelve months. In 132 cases cpioted by Fagg from the Registrar-Gi'ueral's reports, selected because the circumstances regarding the incubation were accurately known, the shortest incubation was eleven days — a case in which a child was bitten by a rabid cat; in 23 cases it was under a month; in 64, be- tween one and two months; in 21, between two and three months; in 24 cases it was more than three months. The average incubation period is about six weeks, but the length is undoubtedly affected by the seat and severitv of the wounds and the atre of the i)aticnt. It is 438 BABIES; UYDBOPUOBIA ; LYSSA. shorter, as a rule, wlicrc the wounds are on exposed parts and very ex- tensive, and is shorter in children tlian in adults. As has been stated, by the inoculation of rabbits with the spinal cord of others dead of rabies Pasteur was able to reduce the incubation period to about seven days, at M'hieh point it remained constant. This virus is known as " the tixe(l virus (cinis fi.rt') of Pasteur." Symptoms in Man. — The symjrtoms of rabies in man present a general similarity to those manifested in rabid animals, although the most striking symptom, that from which the disease in man has derived its name, is peculiar to him. The disease has been commonly called "hydrophobia" in man because during the furious stage violent spasms of the muscles of the pharynx and the elevators of the larynx and hyoid bone occur, which are associated with intense suffering. When the disease is fully develojjed these paroxysms are often brought on not only by attempts at swallowing, but even by the sight of water or food, or, in fact, by any peripheral irritation. Thus the patient, although often suffering intensely from thirst, is tilled with such terror by these spasms that he cannot be induced to make any attemjit to take fluid. The disease may be divided into three stages — the prodromal stage, the stage of excitement, and the jiaralytic stnge. Prodromal Stage. — In the prodromal stage symptoms may or may not be present. In many cases in adults, where the person has been bitten by a dog which is suspected of being rabid, there develojjs gradually, as a result of aiiprehension and fear of the tlisease, intense mental depression. The fear of the disease acts as a constant nightmare, preventing sleep, disturbing all of the functions of the body, causing the patient to relinquish his usual occupation and often to resort to alcohol or narcotics to relieve the mental suffering caused by fear. In some instances the })aticnt may become almost insane from terror even when there is no good reason to believe the animal by which he was bitten was rabid. In (ither cases the flepression dt)es not appear until a few days before the apj)earance of the disease, and then the j)atient becomes de]iressed and melancholy, or nervous, restless, sleepless, and irritable. There may be pain in the scar of the original bite ; it may become swollen, tender, and blue ; in some instances it is said that the scar opens again and discharges a thin watery fluid, or a papular or vesicular eruption appears round it. Occasionally there are severe shooting pains, beginning in the scar and extending toward the trunk. The patient carefully avoids mentioning the circumstances regarding the bite, makes light of the symptoms, and searches for diversion away from home, or it may be seeks solitude at lH>me. There may be even now some in- crease in the sensibility of the special senses, light and sound ])roducing discomfort, and the patient may complain of chilliness while the ther- mometer shows an elevation of temperature of one or two degrees. After a period varying from a few hours to six or eight days the symptoms become more defined and the stage of excitement begins. Stage of Excitement. — This may be considered as really the beginning of the attack. The first svmptoms which arouse suspicion as to the nature of the disease are usually some pain in the nuiscles of the throat and stiffness or difliculty in swallowing. This difticulty in swallowing rapidly increases, and soon any attempts at deglutition are followed by SYMPTOMS. 439 violent spasms of the muscles of the pharynx and hirvnx, and are (ifteii associated with or followed by spasms of the respiratory muscles. An iutense hypenesthesia now rapidly develojis, botii of the nerves of special sense and of general sensibility ; the intensity of the muscular spasms increases and the duration of the interval between them dimin- ishes, while at the sauie tiuie they extend, iiivolvino- not only the nniscles (if the pharynx, laryux, and respiration, Init, to a less degree, all <)f tlie voluntary muscles of tlie body. At first these paroxysms are l)rougiit on only by attempts to swallow, but later the sight of fluids or food, tiie sound of running water, a ray of bright ligiit, a slight sound, touching the stu-facc of the skin, or an i/ afferent impression may serve to excite the ])ar(ixvsms. During tlie paroxysms the breathing is greatly embarrassed and painful, and is interrupted by frequent short exjiiratory efforts ; tiiere is great suffering and a sense of impending suffocation. The expression of the face shows most intense anxiety and apprehension. The patient, although suffering intensely from thirst, refuses to attempt to drink, or wlicn the litpiid touches his lips draws back in terror because of the recurrence of the spasms. Tiie spasms are of variable duration, lasting from a few seconds to several minutes, and in rare instances death has taken place during a paroxysm from aspiiyxia. The muscular contrac- tions are of a tetanic character, although opistiiotonos does not occur. At first the mind is unclouded, but later delirium is frequent, and is especially marked during the paroxysms ; at such times " tlie patient may make violent efforts to strike or injure tlie attendants about him, and cries, howls, strikes or attempts to bite others or himself, until lie sinks back exhausted, and remains quiet until aroused by anotlier par- oxvsm." As a rule, the mind is clear in the interval between the par- oxysms. There is a great increase in the secretion of saliva : it is thick and tenacious, and, as the patient cannot swallow it, it drivels from the mouth or he violently attempts to spit it out. The spasms of the mus- cles of the throat and chest are often associated with the production of a peculiar sound which the imaginative bystanders transform into a bark. It is this that is described when the patient is said to " bark like a dog." Pyrexia is, as a rule, moderate, although the temperature may go to 104° or 105° F. Vomiting is common, the matter rejected being usually of a greenish-brown color. There may be incontinence of urine and fieces. The urine often contains albumin in large quantity, and there may be casts and blood. Sugar is occasionally present. The mental delusions are frequently associatcil in a strange way with animals, and especially dogs, and the mental excitement and fear are stronglv increased bv the sight of a dog. In children the mental dis- turbance is connnonly less marked, and it bears some relation apparently to the dc]iression'and disturbance caused by the fear of the disease wliii'h has preceded its advent. The stage fif excitement lasts a varying j)criod, from a few hours to eight or ten days. As a rule, however, cases termi- nate in four or five days. l'(ir(di/flc Star/e. — A few hours before deatii the paroxysms become less severe and occur at longer intervals. The ])atient may be able to swallow and take I food without difficulty; tiie mind may again become clear, but the pulse is rajiid and feeble, and the disease soon terminates in death. Occasionally there is more or less complete paralysis, com- 440 RABIES; UYnRorilOBIA ; LYSSA. nienpiii^' in the muscles of the jaw and involving partially or completely all the muscles of the body (paralytic rabies), and rarely coma occurs. In a few cases, where persons have received very extensive bites from wolves on exposed parts, the disease takes early the form of paralytic rabies. This is also true in a few cases whei'e death has occurred after inoculation according to Pasteur's method. In children the mental symptoms are usually less pronounced, and the disease terminates earlier in death. Prognosis. — Where the symptoms of true rabies have once devel- oped there is no reason to look for recovery, for, although tliere have apparently been a few cases which have recovered without treatment or under various modes of treatment, they are of such rare occurrence that they give little reason for hope in any individual case. Nevertheless, the various means of symptomatic treatment recommended should be employed to relieve the severity of tiie paroxysms. The percentage of eases in which rallies follows the bites of animals shown to be rabid or supposed to be rabid is variously estimated — from 5 to 60 or 80 per cent. The bites of wolves are most virulent, and next those of cats, foxes, and dogs, in order. Bites on exposed parts are far more likelv to l:)e followed by the disease than those upon covered jiortions of the body, and punctured or greatly lacerated wounds are apparently the most dangerous. Horsley estimates the percentage of eases of hydro- phobia following the bites of animals shown to be rabid as about 16. Boul6, however, says that the proportion fixed by Hunter (5 per cent.) approaches nearer the truth. Following bites by wolves the percentage of cases is i\ir higher, varying apparently from 40 to 80 per cent, of those l)itten. Diagnosis. — Great suspicion has been thro\\n upon the diagnosis in a large proportion of the cases of reported rabies, and much has been written about lyssophobia or pseudo-hydrophobia, the residt of fear. Numerous cases have been recorded in which patients apparently sufler- ing from true rabies suddenly recovered when the animal by which they were bitten appeared before them well or when they were convinced in some other way of the absence of rabies in it. In a well-marked case of rabies there should be no great difficulty in making a diagnosis. No doubt a part of the difficulty usually ex- perienced is due to the extreme rarity of the disease, few physicians in this country having had the opjiortunity of seeing a single case. By far the most characteristic symptom is the peculiar respiratory spasm caused by attempts to swallow li(iuids, and where this is present increased significance is given to it by the history of a recent bite. Tliere is rarely some difficulty in differentiating rabies from tetanus and certain forms of organic disease of the lirain and insanity, but in true rabies the occur-, rence of the respiratory spasms with increasing intensity and frequency, the intense hypera?sthesia, and the existence of great mental disturbance — these symptoms followed j)erhaps l)y paralysis — make the diagnosis clear. The absence after death of gross lesions sufficient to account for the condition during life increases the ceitainty of the diagnosis. This mav be absolutely confirmed by the inoculation of rabbits with the spinal cord after the sul)dural method of Pasteur. Pathological Anatomy. — There is a remarkable variation in the PATHOLOGICAL ANATOMl'. 441 post-mortem lesions found in different cases of rabies as it occurs in animals. Not infrequently there are no macroscopical changes found after death which are in any way characteristic, Init in those cases occur- ring in dogs, which may be considered most tyi)ical, we find that the mucus membrane of the mouth and fauces is greatly congested and covei-ed by a thick, tenacious, mucous or muco-purulent secretion, often mixed with dirt. The mucous membrane of the larynx, trachea, and bronchi may also present similar appearances. The lungs are usually congested, and there may be petechial liemorrhages into the pleura. The heart and the large vessels arising from it are filled with dark blood, completely fluid or containing only soft dark clots. The most characteristic changes are found in the stomach. This is usually filled with all sorts of foreign bodies if the animal has been free, or, if it has been confined, with such as are within reach. In animals which have been running loose, hay and straw, pieces of w"ood, coal, leather, })ortions of cloths, stones, sand, earth, and ficces are indiscriminately mixed together, and not infrequently similar contents are found in the small intestines. The large intestine is often empty. The mucous membrane of the stomach and of the small intestines, particularly of the stomach, .shows clianges quite similar to those found in the throat and larynx, but in a higlier degree. The mucous memlirane of the stomat-li is intensely swollen, hvpeneiiiic, filled with extravasations of blood, and may be the seat of nuiuerou-; ciosions. It is covered with a thick, tenacious mucus. i'lic jiif; -linal nuicous membrane presents the same appearance in a less (iegree. The kidneys are commonly swollen, of diminished consistence, and show marked hy])era3mia. The bladder is emjity, or at most C(jntains a small (piantity of cloudy, and it may be albuminous, urine ; occasion- ally the urine contains blood. The mucous membrane of the Itladder is also swollen, and sometimes shows petechial hemorrhages into its sub- stance. In the central nervous system there are no characteristic changes visible to the naked eye. As a rule, there is marked hyperemia of the spinal cord and the medulla and their meninges, and occasionally minute hemorrhages may be found in tiie floor of the fourth ventricle. The brain and its meninges may also present the same appearances, but these are not constant or eharacterlstie enouo-h to have great sionificance. Not infrequently, especially in those cases which terminate rapidly, there may be few or no lesions in any way characteristic. The stomach may be empty, and at most the mucous membrane of the respiratory and alimen- tary tracts aj)]3ears swollen and somewhat hy]iera?mic. The intestines may contain no normal jn'oducts of stomach digestion, and the contents show littl(> or no bile-staining. There may be nothing else abnormal found in the thoracic or abdominal viscera. The brain and spinal cord may present no changes. In man the post-mortem changes apparent to the naked eye are essentially those of an acute infectious disease, with possibly more marked congestion of the mucous membrane of the alimentary and respiratory tracts, and more marked hv]5er;emia of the lirain and spinal cord and their meninges, than is usually present in other types of infectious disease. It is, however, rather the absence of characteristic changes M'hich is significant in post-mortems on suspicious cases than the presence of any definite gross lesions. 442 RABIES; HYDROPHOBIA; LYSSA. The microscopical finding's in tlic spinal cord and medulla are more characteristic, and assist in tlie diagnosis of doubtful cases. Sections should lie made through the hulh or cervical division of the cord. In these regions there is found microscopically marked hypersemia, with perivascular foci of embryonic cell infiltration, and little nodules of em- bryonic cells surrounding degenerated or proliferating nerve-cells. If these nodules are not found, probably the case is not rallies; if found, probably the case is rabies. The nodules arc less conspicuous in animals killed in the first stages of rabies than in those which have succumbed to the disease. We ma}^ also find (1) hypenemia and acute (jedema of the meninges, with small hemorrhages around some of the vessels; (2) proliferation of the epithelium of the central cerebro-spinal canal, hemorrhages in the gray matter, and obliteration or throndjosis of some of the small vessels by a hyaline pigmented substance, by leucocytes, or by hyaline degenera- tion ; (o) little foci of degeneration in the gray matter. These foci are often visible to the naked eye. The lesions of the nerve-cells in special regions are characteristic. They consist in the signs of proliferation, and even in the presence of several small cells in the pkjce of a large one, or in a uniform degenera- tion. jMonomiclear, and rarely i)olynuclear, cells of lymphatic origin invade the protoplasm of the cell and fill the pericellular lymphatic spaces, dilating them to form nodes (Roux). When a human l)eing has been l)ittcn by an animal which has been afterward killed, it is advisable, if possilile, to make a diagnosis from the autoj)sy and the microscopical examination of the medulla antl cord, so that ])roper advice may be gi\'en regarding the necessity of treatment. Prophylaxis. — The importance of prevention in any disease is pro- portionate tx) its frequency and mortality, and while in hydrophobia, because of its rarity in man, the prevention is seemingly of less import- ance, yet, because of its almost universally fatal ending, pro})hylaxis becomes of great moment. As there is positive proof that the disease is the result only of infection, and, in the vast majority of cases, of infection through the bite of a rabid animal, the prevention of hydro- phobia in man resolves itself into the jirevention of rabies in animals ; and experience has shown without question that the disease in animals — in dogs — can be completely stani]ied out by the eificient enfn-cement of laws rec[uiring the registration and muzzling of dogs. In Prussia the disease has become practically extinct through such means ; in Holland the same is true ; and, in flict, in every country, city, or district in which laws requiring the muzzling and registering of dogs have been efficiently enforced the disease has promptly and completely disappeared. Treatment. — Preventive. — In 1885, after a long series of exper- imental investigations on animals, Pasteur announced the discovery of a method for the jirevention of rabies in those who had been bitten by rabid dogs, and in July of that year he first apjilied the treatment to a human being in the case of a boy named Joseph jNIeister. The Pasteur system of treatment dejiends upon the following obser- vations : (1) the rabic virus is especially present in the medulla and spinal cord of animals dead of rallies; (2) by the successive subdural inoculation of rabbits with an enudsion prepared from the spinal cord TREATMENT. 443 of an animal dead of rabies the incubation period is gradually shortened until it tinally becomes fixed at seven or eight days ; (3) spinal cords removed from animals that have died after such inoculations, if dried in sterilized jars over potash at a temperature of about 73° F., gradually lose their virulence, and at the end of fourteen days are innocuous when used for the inoculation of animals or men ; (4) if an animal or man is inoculated on succeeding days with the spinal cords which have been dried for successively sliorter periods, the individuals are gradually rendered insusceptil)lc to tiie more virulent cords l)y tliosc of less viru- lence which were previously used ; (5) if these inoculations are made after an individual has been bitten by a rabid dog, protection may be still conferred in the majority of instances, providing too much time has not elapsed between the bite and the beginning of the inoculations. The fornuda for the treatment t)f ordinary l)ites (not those about the head) is given below : 1st day, cord of 12 I 14 diivs in dose of 3 cm. of emulsion.

From 1886 to 1891, inclusive, nearly 10,000 persons were inoculated in the Pasteur Institute, with the result as shown below : Year. Persons treated. Deaths. Percentage of mortality. 1886 2671 25 .94 1887 1770 13 .73 1888 1622 9 .55 1889 1830 7 .39 1890 1550 5 .32 1891 1559 4 .25 In these statistics, in the later years the deaths have been excluded when they occurred within fifteen days of the la.st inoculation, as it was then assumed that the virus intniduccd by the bite was acting on the central nervous system before imnumity had been conferred by the inoculations. There were five cases of this kind in tlic year 1891, which have been excluded from these statistit-s. The cases treated have been divided into three classes : (a) persons bitten by dogs in which the existence of rabies was proved by inf)eula- 444 RABIES; IIYDROPnOBTA ; LYSSA. tion or by the sul)s('([utMit iiccurrciicc of" raljics in iinotlicr aniiiuil ; (b) persons bitten by animals in whicli the existence ot" rabies was confirmed by a veterinary surgeon ; (c) persons bitten by animals suspected of having rabies. Roux refers to 710 cases treated in Class a, where the bites were on exposed parts about the head, in which only 24 died — a mortality of 3. .38 per cent. He declares that the mortality in this class of cases with- out treatment would be about SO per cent. It is particularly in those cases in wliich the bites are upon exposed parts that the mortality is greatest. Whether we accept as final oi- not the statistics of the Pasteur Insti- tute as t( > the efficiency of the treatment, yet it may lie safely concluded from the results of the Pasteur inoculations that tiicre is comjtarativclv little danger from the inoculation itself, and that the mortality in ])ersons after treatment bitten In' dogs knoMn or suspected to be rabid is far lower than it has ever been before. Treatment of Bites. — In the immediate treatment of bites from ani- mals supposed to be rabid the main object is the elimination of the poison. If the \vound is in an extremity, where the circulation can be controlled, a ligature should be immediately applied, bleeding promoted, the ])art thoroughly soaked in an antiseptic solution, or, if it is a punc- tured wound, the wound sucked and the mouth afterward repeatedly washed out with a disinfecting solution ; intermittent squeezing and wringing of the ]iart while it is soaked in warm water is an excellent method for jiromoting bleeding and eliminating the poison. The M'ound may be o|)ened to its depth and cauterized witii actual cautery or with mineral acids or nitrate of silver, or the wound may be excised. Tlie more quickly and completely the poison is eliminated after the bite, the less is the danger from the bite. However, there is good reason to believe that even if the treatment of the wound is not begun until some hours after the wound was inflicted, yet a considerable measure of pro- tection may l)e thus granted, for it seems probable that the poison may be localized for a considerable period at the point of its introduction ; hence in any case where it is thought possible that the wound was inflicted by a rabid animal it should be thoroughly washed and cauter- ized even if a considerable period has elapseil since the injury. Therapeutic. Treatment. — During the incubation period the psychical treatment is of special importance. Great care should be taken to dis- tract the patient's attention from the subject of the bite, and nothing should be said or done which directs attention to it. The other meas- ures during the ])criod of incubation pertain simjily to general hygiene. After symptoms have appeared there is little reason to anticipate anything but a fatal rcsidt, and the treatment should lie purely symptomatic, and consist in the use of spinal and cerebral sedatives and antisjiasmodics. Some observations have recently been reported — jiartieularly by Chantemesse, Tizzoni, Centanni, and Babes — M'hich offer bright hof)e in the early future of the perfection of a specific means of treatment of hydrophobia through the use of an antitoxine separated from the blood of animals which have been rendered artificially imnume to rabies. The observations thus far made, however, arc as yet too incom- plete to render the measures available for the practical treatment of hydrophobia. GUNSHOT WOUNDS. By p. S. CONNER, M. D. No class of injuries has more occuijicd tlie attention of surgeons and surgical writers than tliose jjroduced l)y gunshot, and from the study of no other class has greater benefit accrued to the art of surgery in general. But the great changes that in very recent times have been made in weapons, in missiles, and, especially, in the treatment of all wounds, necessitates reconsideration of not a few questions connected with the nature, tiie care, and the results of these wounds ; respecting which mucli that has been written is now of historic rather than practical value. As met with in civil life, gunshot wounds are commonly produced by pistol halls or small siiot ; in military service, by rifle bullets, by large solid shot or shell, or by balls tin-own out from case or canister shot. A small proportion of the injuries are caused by caps, by por- tions of a gun whicli has burst, or by a splinter of wood or a piece of stone or metal set in motion by impact of a shot. Missiles. Small shot vary greatly in size and weigiit, the extremes being " fine dust," the particles of which weigh less than 2^,5- gr. each, and buckshot of .44 in. diameter and 153 grs. weight. Pistol balls also are of various shapes, sizes, and weights, ranging from a calibre of .22 to .45 of an inch, and a weight of from 25 to 250 grs., all more or less conical, made Country. Austria .

Until recently army bullets were of large size, those employed in our late war varying in calibre from .50 to .71 of an MISSILES. 447 incli, and in weight from 400 to 760 grs., and even to-day the service bullet of our army has a diameter of .45 in. and a weight of 500 grs. Yerv soon, however, in common with other nations, we will have a iitandard ritle of small calibre and a l)ullet of tlie modern type, long, slender, cvlinnly when near the end of a long flight or after having previously encountered much resistance, these new bullets may be expected to produce lesions in many respects different from tho.se met with heretofore. Experimentally, much has been determined, and the limited experience that has been had in recent wars in Africa, South America, and Asia conflrms the results of the experiments made by European and American surgeons' upon animals and human cadavers. Gexerai. Consider.\tions. — With few exceptions, gunshot wounds are of the lacerated and contused order. According to direction and momentum, the shot may graze or bruise the surface of the body, may enter and lodge, or pass through and out — in other words, contuse, pen- etrate, or perforate. In proportion as tlie bullets have been made harder and their velocity increased the likelihood of their lodging in the body has been lessened, so tiiat even in the pistol wounds of civil life perfora- tion is of frequent occurrence, or the bullet is often found to be lodged just under the skin, the elasticity of which has prevented its passing through. Leaving out of consideration the injuries inflicted within tlie " zone of explosive action " and aft'ecting bone, tliat witli few exccjitions have up to the present time been only experiiiK'ntaliy produced, and in wliich the exit wounds are 6f very large size, the old-time great difference in the size of the wounds of entrance and exit no longer exists, even when the ball has passed through bone. The diameter of each wound is aliout that of the Itullet ; it may be a little smaller, it may be a little larger. ' See table at font of pajje 445. - The degree of (jenetratian as rompared with that of the old bullet is shown by the accompanving figure (Fig. 14 1, taken from Asst. Snrg. La Garde's report to the Surgeon- General of our army.

The skill about tlu' wotiiid of entrance is often somewhat depressed, about the wound of exit everted. Both wounds may appear as if made with a punch ; that of exit is very often stellate, ti-iangular, or even linear. A narrow dark-colored ring surrounds the opening, especially that of entrance, due not to the heat of tlie shot, but to the extravasation of blood from vessels of the superticial fascia, which because of its lessened elasticity is somewhat stripped off tlie skin. As far liack as the time of Pare and Maggius it was demonstrated that the shot was not hot enough to ignite gunpowder in sacks into which it had been fired, and could not thei'efore burn the edges of a wound. W^hen the wound has been inflicted at very close range powder-staining of tlie parts has been often observed; with the use of metallic cartridges and the improvements in powder manufac- ture, securing more tiioroiigli combustion, such staining is becoming less and less frequent. The distance at which the marking may occur is by no means absolutely determined (as reported, varying between 2 and 10 feet), and cannot be definitely stated because of the variations in the quality of powder used. In some experiments made by Professors Frost and JJartlett of the I)artmoutli jMedical College three years ago with Winchester-rifle cartridges cal. .44, fii'ed from a revolver, it was found that at 3 feet distance heavy wrapping paper was " perforated with clean Fig. 15. ;Miiltipk' shot-wounds of anas nnd Imck. The opcMiinp art, at least, an explanation of the observed differences maybe found in the lat- eral swing of the ball before its axial rotation is thorouglily established and after its velocity becomes greatly diminished, as in the early and late wabbling of a top, which spins steadily during the middle period of its rotation. So great is the destruction effected in the shorter ranges that these latter constitute a "zone of explosive action," tlie middle distances belonging to the " zone of penetration," beyond which, near the end of the missile's flight, is the "zone of contusion." The most inten.se explosive action is seen in wounds of tissues rich in fluid contained ' As illustrating the splitting of a bullet, Figs. 16 and 17 are given of specimen in the Array Medical Museum at Washington. Vol. I.— 2S) 450 GUNSHOT WOUXDS. within comparatively iinyieklin^ walls, as in lesions of the brain, though saeh hydrostatic — or, better, hydrodyiianiie — pressure may be strongly exerted ujjou the solid viscera of the abdomen, and even upon the hollow viscera wlien full (if fluid or semi-fluid contents. The course of the ball may be expected to be direct. Deflection of the new army bullet will probably never occur, and as the pistol ball is made harder and the (juality of the powder improved, it will become more and more rare to find in civil life a change in the line of direction. Even with tiie soft-lead conical ball such change is not very likely to happen, and in many cases in which it has l)een believed to occur the course has been a straight one, the body as it was struck having been put into such position as to give an appearance of deflection. Much less frequently than before will blood-vessels in the track of the bullet escape injury ; but the smaller .size of the missile and the diminished cross-section of the ai'ea of devitalization must lessen the number of vessels damaged. Nerve-trunks are more likely to be uninjured than the vessels. As a rule having comparatively few exceptions, the damage done by a bullet is produced in its passage, and when it lias come to a state of rest it commonly ceases to do harm, at least wlien the lodgement is in the soft parts. Though when so located it sometimes changes position because of weight and muscular action, it ordinarily does not, but quickly becomes encapsulated and fixeil. In one of the softer viscera, especially the brain, it may produce serious pressure-symptoms either where pri- mai'ilv ])laced or in some more de])endent position to which it has in time gravitated ; resting against the wall of a hollow viscus, it may afterward by ulceration reach its interior. That lodgement has occurred may be inferred with almost absolute certainty when there is present a wound of entrance only. The old- time round ball, even of considerable size, sometimes carried in a piece of clothing, in which it rested as a finger in a glove, and with the with- drawal of such pocket the shot was pulled out ; but the bullet of to-day is excessi\ely unlikely to behave in such manner. In a few cases on rectnxl the shot has passed out of a natural opening, as in other cases it has entered through such. Determination of the position of a bullet may be made by palpation of the injured area or of the surface toward which tlie shot was tending, bv digital exploration of the wound, by jjrobing, and by the use of an electrical apparatus. Very often the desired information will be gained by palpation, and in the wounds of the external soft parts met with in civil life a bullet that cannot be thus located had better be let alone rather than sought for instrumentally. "When the track of the ball is large enough to permit of the use of the finger, this best of instruments should be employed, as by it can be well ascertained the nature and extent of the damage done. By it alone can the ]iresence of pieces of clothing be determined. Enlargement with the knife of the wound of entrance and of the track, of which in the jKist there have been many strong advocates, is certainly not required in cases of pistol-ball injury, and with the new military rifle the wounds in very large proportion will be those of perforation, not penetration. If in any given case there is good reason for believing that a piece (not shreds) of clothing has been carried MISSILES. 451 in with the l)all, careful search for it slioiild he made with the fin<>'er, with or without enhirgement of the wouikI according to circumstances. By no probing with a metallic instrument can the presence of cloth be ■determined, and if left in place it is certain to be a source of infection. Fortunately, the modern conical bullet with its great velocity compara- tively rarely carries in with it this septic complicating foreign Ixxly. If a probe is to be nsetl, it should be bulbous-ended and of a diam- eter but little less than that of the bullet, is best made of aluminum, because of the lightness of this metal, and never should be employed without precedent thorough cleansing. Under no circumstances should a gunshot wouny the oltl large- calibred, soft-lead bullet. As a rule, the closing of the track com- mences in its central portion and proceeds thence toward the wounds of entrance and of exit, the former commonly healing last of all. Such closure, especially in lesions of the soft jiarts, may and frecjuently does occur without suppuration ; more often the jius-formation is slight, and chiefly in and near the entrance wound, and this even tliough bone has been damaged. It is the recognition of these facts that is leading sur- geons more and more to treat at least pistol-ball injuries in the most simple manner, actively interfering with the wounds only when pain, heat, and swelling make it evident that foreign bodies are to be re- moved or free drainage secured. When, in consequence of small-shot injury of an extremity inflicted at very short range, or of a rifle-ball laceration within the zone of explosive action, or of a crush by a large shot or a large fragment of shell, a limb is very extensively mangled, amputation will generally be required, or, but less often, an exseetion. It will, however, doulitless be found that such operations will be much less frequently demanded in the future tiian they were in former times, just as it is now with cases of extensive compound fractures due to traumatisms other than gunshot. The primary effects of a gunshot wound (shock, pain, and hem- orrhage) are to be treated in the ordinary way. As has already been stated, bleeding in any considerable amount is not of frequent occur- rence in the generality of flesh wounds, though a moderate degree of oozing during some hours, or even days, may lie expected. Bone wounds are attended with a greater loss of blood, but, as commonly met with EFFECTS UPON THE VARIOUS TISSUES 457 in civil life, the iu'iiiorriiage in connection witli them does not necessi- tate any special treatment. In the lesions of tlie liead, chest, and abdo- men serions hemorrhage very often is present, and, as we siiall see iiere- aftcr, in many cases demands prompt operative interference ; and the same is trne of wonnds of the neck, tiie axilla, and the groin. W'liere vessels of larger size, arteries or veins, have been torn, recourse must be had to either compres.sion or ligation. Compression often answers a good purpose when jmiperly and methodically a[)])lied, more so in cases of vein-wounds tlian in those of arteries, but wlien tlie l>Iecding is at all ])rofuse tlie wounded vessel should be freely exposed and tied above and below the point of injury. Chemical styptics — e.g. tiie per- salts of iron — should never be employed : again and again they have proved inefficient and their use productive only of evil. If cold (or, much better, h(it) water does not stop the bleeding, compression or the ligature siiould l)e applied. In a few of tiie cases in which the main artery and vein of a limb have been sinudtaneonsly lacerated am[)utation may have t(j be performed to prevent the occurrence of gangrene of tiie extremity. Secondary hemorrhage when it takes place (and it may occur at a very late day) will ordinarily necessitate ligation of the vessel — in the wound if possible ; if not, well above the level of injury — thougli at times com])ressiou has proved of service, or even the laying open of the wounded part. Wiiether or not ligation should be done when tiie vessel is not bleeding has long been a question. There may be no recurrence of the hemorrhage, and the disturbance of the wound necessary to the tying can only increase the gravity of the situation ; on the other hand, if ligation is not done, a later l)leeding may occur — fatal it may be, cer- tainly adding to tlie existing danger. As a general rule, the wisest course is not to ojierate after a first bleeding, but to do so always after a second. There is every reason to believe that in the military practice of the future secondary hemorrhage will be much less frequent than heretofore, due as it is to suppurations and septic processes that can be largely prevented by antiseptic treatment. In civil practice secondary bleeding is of very infrequent occurrence. Effects upon the Various Tissues. Skin. — According to the velocity of the bullet and the angle at which it strikes, the skin may be merely grazed, strongly contused, or jicne- trated. In the former case there will be developed an erythema which will soon subside, or a superficial devitalization mav be efil'ctcd, causing the formation of a thin dry slough, the separation of which will be followed by slight scarring. 'When the contusion has been more severe, without material injuiy to the parts beneath, under antiseptic treatment the slough (which may include the entire thickness of the derm) will still be dry, and when its se]iaration takes place it will be found tiiat there has l)een healing under the crust. In rare instances the elasticity of the skin will prevent its laceration, although the tissues beneath are extensivelv crushed, as has been observed in certain cases when the part has been brushed by a large shot or massive piece of shell in full flight or struck by such when nearly spent. Not seldom when the ball ])asses for quite a distance just 458 GUNSHOT WOUNDS. iinr tho skin its trnok will he marked hv a deeji diseoloration of the iiiteti'iiineiit, and the at'ter-sejiaratidn of the slough will leave a depressed guttered wound, and later a eicatrix. Fascia. — The formerly often-observed deflection of a ball by a layer of firm deep fascia very rarely occurs when the wound is j)roduced by a pistol shot of to-day, and can never do so when the missile is one of the new army bullets. The fascial fibres being in considerable measure separated rather than torn, some closing in of the openings through the layers may be expected, which may render ])robing more difficult and drainage less free and complete. It is not likely that surgeons of the future will see, other than very exceptionally, permanent openings with rounded edges in the outer layer of the deep fascia, through which hernial protrusion of muscle can occur— openings tliat were frequently the result of wounds made by round balls and the earlier-employed large conical bullets. Muscles. — As made by bullets, except within the zone of explosive action — and there is no such zone with reference to jiistol shots — muscle- wounds are not attended with any extensive destruction of tissue, and the associated blood-extravasations arc not large. When the shot jiasses in the line of the muscular filircs there may often lie separation rather than destruction, rendering it very difficult, it may be impossible, to follow the track. Passing transversely, though the laceration may be quite great, there is very seldom a complete severing of the muscle. ^Mien struck by large shot or a large piece of an exploded shell widespread destruction is effected, with resulting great loss of substance and the after-formation of an extensive and deep scar. Tendons are more often severed, but as a rule a piece is cut out or a perforation made. At times the impact of the shot causes a rupture of the muscular belly above, the tendon itself being only contused. Whether or not the tendon will often be pushed out of the way by the new bullet, and thus escape injury, remains to be seen. Blood-vessels. — Arteries and veins in the track of the modern bul- let, pistol or rifle, especially the latter, will rarely if ever be uninjured. As before, they may be completely or partially divided or may be con- tused, with liability to the later occurrence of hemorrhage or the formation of an aneurism. Associated perforation of both artery and vein may be followed l)y the development of an arterio-veuous aneurism. Nerves. — Contrary to what was formerly true, nerve-trunks are less likely to l)e damaged than the larger blood-vessels. When in tho path of the ball they generally, however, are torn or contused, with resulting impairment or entire loss of motion or sensation ; pain of greater or less severity and continuance, at times burning (causa/c/ia) ; trophic changes ; or absolute destruction of the vitality of the parts to which they are distributed. Boxes and Joixts. — Among the more serious lesions met with in military practice are wounds of bones and joints, which constitute about one-fifth to one-fourth of all the injuries coming under care. In civil life the proportionate number is much smaller and their gravity is as a rule nmch less, caused as they generally are by bullets of less weight and, still more, less velocity. A bone injured may be either contused or fractured according to the EFFECTS UPON THE BONES. 459 angle at which it is struck, and, especially, the momentum of the bullet. Contusions jn'oduced by pistol balls, more often of course those of small calibre, are frequently of sucli sliu'ht severity (mere jarrings) that their existence is unsuspected or thought probaljle only because the missile, flattened out it may be, is found resting against the bone. More often, the blow being stronger, some subperiosteal extravasati(.)n occurs, and in a limited number of cases the impact of the shot is sufficient to destroy vitality, the necrosed, later separated, piece of bone varying nuich in tiiickness. Musket-liall contusions, which were formerly not uuconunon, and were often followed by local and general septic infection, will in all prob- ability be almost or quite unknown in the future, the new rifle bullet fracturing, not bruising, any bono that it may strike. Antiscptically treated, the bone-contusions may be expected to lie rapitlly recov- ered from without either permanent thickening or persistent neuralgia resulting. Fractures are of various kinds, according to the force and angle of impact, the character of the bone struck, and in the long bones the part injured, whether in the shaft or near the extremity. Whatever they may be, they are, in general, due to contact or penetration, the former being mediate or immediate, the result of a tangential or a direct blow ; the latter partial or complete, tiie Ijall entering and remaining, or passing entirely through to lodge in the soft parts or emerge tiu'ough the skin. The simplest form of contact-injury is a mere crack, of greater or less length, curving oftentimes at its extremities — a lesion of little moment, very frequently overlooked, and recognizable with great difficulty except upon actual inspection. Percussion, by developing the " cracked-jiot " sound, lias at times been of diagnostic value, and it may be that evidence of importance may be affi)rded by the pain in a limited area, which has been shown to be produced by the passage of a galvanic current tin-ough a broken bone. As an exaggeration of this linear fracture there may be a fissure, the edges of the crack separating somewhat, in a superficial lione ])ermitting of recognition of the gap upon palpation. When such fractures are pro- duced by direct strolce, the missile must have in large measure lost its momentum. Rarely, but probably more often than has been sup])osed, the crack or fissure may extend transversely or obliquely through the entire thickness of the bone, causing the simplest form of a complete fracture, and in a few cases such sej)aration has been found to have occurred not in the area directly injured, but at a level considerablv above or below. Because of tiie al)sence of nniscular traction upon them, or of an incomplete tearing of the periosteum over them, the fragments may remain in apposition,' to be perhaps later separated by movements of the part or by muscular contractions after the untorn periosteal bands have softened. These contact-fractures, which, as has already been stated, will often be overlooked, require no special treatment. If protected from infectiiiu and the injured area is innnobilized, rapid repair will take place. It is by penetration that the great majority of fractures are produced, the essential character of the injury being a driving in of the part of the bone struck, with or without associated fissures passing out in various 460 GUNSHOT ]VOUi\I)S. directions and to varyinjj distances (Figs. 19, 20, 21, 22, 23, and 24 are from tiie report of ^Vsst. yurg.

The iissures passing out from the centre of violence are also very variable in num- ber and extent, ranging from a scarcely perceptible crack to a complete breaking up of the bone. When the fracture is in the shaft of a long bone the characteristic fissuring, as Dclorme has .shown, is that of an elongati'd x (Figs. 25 and 26), the four primary parts of which may be secondai'ily .split into a few or many pieces.

Almost or <|uite as clean a jierforation may occur at .some dis- tance above the articulating e.xtrcmity, as illustrated by Figs. 29 and 30. As in the case of wounds of the diaphysis, the ball may remain external to the bone, lodge in it, or pass thn)Ugh it, but, because of the lessened resistance of the cancellous tissue, is more likely to ])erforate, making a comparatively clean canal, with an outlet wound commonly a little larger than the bullet. AVounds of the irregular bones much resemble those of the sj)ongy extremities of the long bones, but because of their small size these bones may be expected to be largely sjilintored, without, however, in many cases, much sepai-ation of the fragments. The flat bones may be extensively shattered or perforated, as is much EFFECTS UPON THE BOXES. 4(;3 more often the case now than in former times. The perforation will commonly be found to be somewhat eunical, its edge on the side of exit being more or less bevelled at the expense of the outer layers. Such perforation may or may not be associated with fissures running for a variable distance into the bone.

With the old liullet it extended to 200 to 250 yards, sometimes a little more ; with the new it is increased to 350, 400, or even 500 yards. As La Garde (Asst. Surg. U. S. A.) has stated it : " There are no special features, as a rule, to describe about the wounds of entrance, except the appearance at times of bony .sand in the tract leading to a fractured bone. When a resistant bone has been hit, the foyer of fracture will show great loss of substance : the bone 464 GUNSHOT WOUNDS. will have been driven n(it only in the direction in whieh the projectile ■was travelling, but in all directions, and the pulpifieation of the soft parts will not be limited only to the track of the bullet, but the utter destruction is noticed some distance into the tissue.

EFFECTS UPOX THE BOXES. 465 In certain cases the exit wound has been found to have a length of four, six, or even more inches, and a width of three or four, and occa- sionally honc-fraru prcpjectile at the same range. The bullet struck the crest "f the tibia, passing wholly in fmni of the medullary canal, guttering the crest. There is a complete fracture (..\sst. Surg. La Oarde, U. S. A., loc. cit). Fig. 32. Posterior view. the result doubtless of the wabbling of the sliot ; and such smashing of the bone continues up to the extreme range of fracturing. When it is a ridge or crest of bone that is .struck, or the ball crosses a curved surface tangent ially, guttering is often produced (Figs. 31 and 32), the notch or furrow being at times quite clean cut, at times as.so- ciated with fl.ssurings. A ball im|)inging upon a ridge or ercst may be split into two pieces of nearly iMpuil or very unequal size, either entirely Vol. I.— .'iO 466 GUNSHOT WOUNDS. separated or held togctlier at tlic haso. Similar splitting is occasionally found when it is the convex surltiee of the skull that has been struck. The hardened lead pistol ball is niueli less likely to be affected in this way than is the soft lead one, and sncii splitting will not occur, or only exceedingly seldom, wlien the missile is a jacketed rifle ball. Tiiat fracture by jK'uetration lias occurred may or may not be easy of determination. A\'hen crepitus is recognized, deformity is present, preternatural mobility exists, and the functional integrity of the limb is lost (in other words, when there are the ordinary symptoms of frac- ture), there can be no question respecting the diagnosis, particularly so if in addition there are bonc-fragmcnts or bone-dust in the track of the ball and the exit wound is of large size. Thi' bone-fragments, if found at all, will be between the bone and the outlet wound, except in inju- ries within the explosive zone, when at times small fragments are also carried back toward the orifice of entrance. As a general rule, a length of exit wound exceeding an inch indicates that there has lieen bone- injury ; and, as Delorme has shown, a fairly safe conclusion as to whether or not sucli injury has lieen received may be drawn from inspec- tion of the exit hole in the clothing, whicii is very generally larger in cases of fracture than in those of wounds of the soft parts only. But small size of perforation-wounds by no means indicates absence of bone- lesion or its limited extent.' Occasionally, in the absence of other signs, ]>erforation is made certain by the presence of evidences of injury of a viscus wiiicli could only have been reached after the ball iiad jiassed through the overlying bone. When the symptoms mentioned are wanting and the lesion is rendered likely only because of the direction of the shot, it will often be the wiser course to be content with the establishment of a jirobable diag- nosis, since in the effort to secure certainty the l)onc-iiijurv may be much aggravated and the after condition of the patient made much worse. The primary treatment must of course vary with the extent of bone- injury. \\^hen this is but slight, thorough cleansing of the external wound, and, as far as it may be practicaldc, of the track, being effected, the part, if the lesion is in an extremity, siiould be innnobilized. If more severe, comjjletely detached fragments should be removed if they ' In illustration of the truth of this statement niav be qnoted a recent report of an experimental case observed l)y Lt.-Col. Stevenson of the British army, }irofessor of military surgery at Netley. The tiring was done at a 50 yards' range. "The bullet passed through the ankle-joint, entering the astragalus behind, above the surface for articulation witli the os calcis, and passed out in front through the neck of the bone. The skin-wounds were very small, that of entrance being a little less in diameter than the bidlet, and that of exit a little smaller than the former. On dissection it was found that the bullet had passed through tlie astragalus about half an inch beneath the artic- ulating surface for the tibia. All the astragalus except its head was pulverized, and all its articulating surfaces s]ilit except that for the scajihoid. The lower end of the tibia was fissured in many directions, and to a certain extent pulverized, although the bullet had not actually touched any part of this bone. The cause of this condition of the tibia was evidently the bursting apart of the astragalus while firmly held by the grasp of the two malleoli. The attachment of the external malleolus of the fibula to the outer surface of the tibia did not give way, and the internal malleolus was not fractured; thus 'it was that when the bullet passed through the astragalus, greatly distending that portion of the bone held between the malleoli, the articulating surface of the tibia was sjilit and the lower end of the bone extensively fissured." EFFECTS UPON THE BOXES. 467 can readily be gotten at, the canal drained, the limb imniobilizetl, and antiseptic treatment maintained nntil healing takes place. Fragments which are adherent should be left in })lacc, after having been as much as possil)le ])ressed intd position if found to be decidedly tilted off from the normal line of the bone. Not infrequently a sequestrum which is ajjparently entirely separated is really fastened at one extremity by peri- osteal bands, and its removal can be accomplished only with difficulty and with resulting increase of damage to the bone. When so fastened it should be treated as an adherent fragment, since if sepsis is prevented its vitality will probably be preserved, and if not it i-ui be extracted later. Until recently the general rule has been to remove an impacted ball, wound-infection being almost certain to occur, and, if the foreign body was left, necrosis of greater or less extent of the bone was quite sure to follow ; and now, if the missile can be located and readily taken awav, such removal should be made. But if, as is so generally the case in pistol-shot injuries in civil life, to find and remove the bullet necessi- tates doing much damage to the parts, it had better be left undisturbed. If protected from wound-infection the injured urea will generally do W'cll, whether the missile is left or is taken away. When the shot has gone through and out and the crushing has not been very great, as it will not be except at short range, the same general principles t)f treat- ment must govern the conduct of the surgeon — removal of se])a rated fragments (and, as has already been stated, they will be found between the bone and the wound of exit), antiseptic cleansing, and dressing and immobilization of the part. When there has been great destruction (as from a rifle ball within the explosive zone, a load of shot from a gun but a few feet away, a large shot, or a shell fragment), whether or not the liml) can be siived will depend upon the extent of comminution and the amount of injury done the soft parts. Gunshot fractures, so far as treatment is concerned, do not differ materially from other compound fractures, and if it is possible to employ the same methods of cleansing and dressing, similar good results may be expected. In military ]>ractice, from the necessities of the situation, thorough and rigid antise])tic treat- ment cannot be applied otiier than exceptionally, but from the limited experience of the hist twenty years it may be reasonaldy hoped that much can be done to lessen the old-time mortality of bone-injuries. In civil life amputation will be required only when the limb has been extensively shattered, and not even then in many cases unless there is an associated laceration of the main vessels or nerves. But on the field, removal of the limb is called for not only when there has been great shattering of bone with or without extensive laceration of the soft parts and injiuy of vessels and nerves, or when a portion of the extremity has been completely devitalized or has been carried away, but also in less severe cases because of the unhealthy surroundings of the soldier, the existing necessity of transporting him long distances, and the limited attention that it may be possible to afterward give him. Neither in civil nor in military practice should anq>utation be done when there is a reasonable probability of sjiving a tolerably useful limb, even though such limb be deformed or the source of some, it may be considerable, discomfort. Often has it hap))ened to surgeons in our country in tiie last thirty years U> see amjmtation stumps that were painful, frequently 468 GUNSHOT WOUNDS. iilconiting', and of little fuiictidnal value. Formal cxsections in the shafts of the long hones, operations " in continuity," should not be done, more of the bone l^eing taken away and the end results being less satisfactory than when there has been an informal removal of non- adherent sequestra. Later in the progress of the case, as in ordinary comjionnd fractures, removal of the limb may have to be made because of infective processes in the part, sujipurations, osteomyelitis acute or chronic, or gangrene. Even under the most rigid antiseptic treatment compression-gangrene necessitating amputation may occur. Joint-wounds. These are either extra- or intra-articular, and, like those of bone, are of greatly varying degrees of intensity. The several joints vary much in liability to injury according to their anatomical position and their exposure to traumatism. As generally stated, in order of frequency are found lesions of the shoulder, knee, elbow, wrist, ankle, hip, though in our late war the wounds of both knee and elbow were more numerous than those of the shoulder. Extra-articular injuries might well be considered simply as wounds of the soft parts, were it not for the fact that at times, either because of injudicious examinations or more often of extension of septic inflamma- tion, the synovial membrane is ojiened and the joint involved. A seton wound may be present, or a eonsideralile extent of the coverings of the articulation may be carried away or later destroyed by gangrene. Tendon-sheaths are often opened with or without injury of the tendons, and sometimes because of such openings there is so much discharge of synovia-like fluid as to lead to the erroneous diagnosis of actual jienetra- tion of the joint. The old-time round ball occasionally ran around the joint through a large arc, and some have believed that it is not impos- sible for the conical iiall to take a similar curved course : the probabili- ties are, however, that in the cases in which such wounds have seemed to exist the ball really passed sti'aight from entrance to exit, })iercing the joint-cavity, but speedy closure of the middle part of the track occurred and the joint-lesion gave rise to no wcll-detinod symptoms. Intra-articular wounds may be due to the direct entrance of the ball from without or througli one of the bones of the joint, to primary laceration of the synovial membrane in connection with a bone-fissure or later opening by ulceration, or to crushing of the parts by a large shot or a shell fragment. As a rule having few exceptions, a bullet passing through the joint damages one or both of the bones entering into its composition, fissuring, canalizing, grooving, or notching it or them. In the knee it may traverse the u]iper pouches of the synovial membrane M'ithout causing osseous lesion, or if the leg is somewhat flexed upon the thigh (at an angle of from 150° to 170°), it may pass from side to side below the patella without impinging upon either femur or tibia. That a joint has been injured may be readily determined when there has been extensive Iacerati()n ; when upon palpation much comminution is found to exist ; when great fulness of the synovial cavity is rapidly JOINT- WO rXDS. 469 developed, showing: that tlicre has been a large extravasation of blood into the joint ; when there is free diseliarge of mingled blood and synovia from the wound of entrance or of exit or from both ; or when bone-dust or fragments are found in the exit wound. But when none of these symptoms are present the diagnosis must rest upon impairment of funetioii, ujion escape of synovia, and upon the position of the wounds of entrance and exit with reference to the articulation. Inability to use the limb has little or no signiticance, as it may be any the new bullet, except at short range, will doubtless prove to be decidedly less than by the old, canalization being largely effected, with but a moderate amount of associated splintering and nnich less separation of the frag- ments. Lodgement of the bullet, occasionally observed heretofore, is 472 GUNSHOT WOUNDS. not to be expected ; even in tlie pistol wounds of civil life the ball rarely fails to perforate. Determination of the part of the hunierus struck, whetlier head or neck, annti>nii('al or surgical, must rest usually upon the positions of the wounds of entrance and of exit, and is really a matter of very little importance. That a fracture of any kind has occurred will often be knt)\vn only from the direction of the shot, the fragments being so held together that neither crejiitus, preternatural mobility, nor deformity can be discovered. The prognosis may now l)e regarded as very good in cases uncom- jilicatcd with lesions of the larger vessels or nerves or of the chest, and in individuals whose personal condition and hygienic surroundings are not bad. Formerly it was otherwise ; the mortality-rate during our war was 34 per cent. But statistics of date prior to twenty years ago liave only an historic value. The treatment in civil life is l)y expectancy, and doubtless will be so hereafter in army practice. Amj)utation will be reserved for cases of extensive crushing and of associated laceration of the important structures in the axilla. Even in these last conservatism will be largely employed in non-military traumatisms. When both scapula and clavicle are injured, as well as the humerus, it may at times be advisable to amputate high up, doing an interscapulo-thoracic opei'ation after the method of Bergcr. Excision, which was so much favored and so extensively practised in the ten years between 1861 and 1871, will rarely be employed, for it has proved, as observed in our own country and in Germany, that the late condition of the great majority of those thus ojierated upon is far from being satisfactory,' and a more useful lind) may reasonably be expected to be secured by conservative treatment. Moi'eover, so far as we may infer from the experience of our late war, excision is more dangerous than either conservatism or amputation (36.6 per cent. ; 27.5 per cent. ; 29.1 per cent.), and, though the present wound-treatment will greatly reduce the mortality-rate, the reduction must apjily ef|ually to the three methods of treatment. Elbow. — These injuries, which constitute about one-tenth of the wounds of the upper extremity, are occasionally jieriarticular, but very generally perforative, the missile rarely lodging. In a few instances the capsule has been opened without any bone-lesion being produced, usually when the forearm is somewhat flexed and the ball has passed just above the olecranon. The extra-articular wounds, pro{)er]y treated, are of importance only as there is serious nerve-injury or because of hemorrhage. As in other articular lesions, the extent of damage to the bones varies within wide limits, but in a large projiortion of the cases as now met with comminution is not great, and the fragments are chiefly, it may be entirely, held in close relation with each other. The humerus, the ulna, or the radius may be wounded, or any two of them, or all three in the ' In 213 cases Giirlt found that there were but 4 in which the functional value of the limb was very satisfactory (1.87 per cent.), 90 in which it was good (42.25 per cent.), and in 119 it was either Ijad or very bad (55.88 per cent.). After conservatism in former times an ankylosed shoulder was usually present (in seven-eighths of the cases, according to Chenu) ; after excision there was often a dangle-joint. WOUNDS OF SPECIAL JOINTS 473 extensive crushings of the joint. The lesion of the Immerns may be confined to an epicondyle, may affect only the articulating surface below the epiphyseal line, or may be located in or just above that line. At the present time it may be ex])ected to be less extensive than formerly, wlien the soft-lead, large-caliltre ball was used, an illustration of the destruc- ''^^' ^^' tive action of which is giv^en in Fig. 33. As a rule, the precise character of the injury can be determined only with difficulty, except so far as it is indicatctl by tiie direction of the line joining tlie wounds of entrance and exit. E([ually as a rule, such determination is of little •"'>"' '' a°^L m° spe^il^""'''"' practical value. The complicating in- juries are of the arteries, usually the braciiial, and of the nerves, the ulnar being much more often the one woundeilization, and with the most thorough antisepsis. The result may l)e expected to be not only better than that following operative interference-, but mucii better than that heretofore secured — fewer ankyloses, less impairment of the motions of the hand and fingers, and much more perfect use of the preserved joint. It is not likely that under the present method of dressing from first to last a future investigator will find, as did Dominick after the Franco-(Tennan War, that in 163 cases there was complete ankylosis in 82.8 ])er cent., incomplete in 11 per cent., and free mobility in l)ut 0.2 per cent. Aminitation, as has already been stated, is indicated only when there has been great injury to both bones and soft parts. Excision, which 474 GUNSHOT WOUNDS. done for disease is liifjlily successful, and wliicli was extensively tried in the late wars in our CDuntrv and in Eurojie, is not now regarded with favor hv the irreat majority of surgeons. Its mortality-rate in ])re- asej)tic days Mas from 20 to 25 per cent., and that whether the ui)era- tion was partial or complete, and the end-result was not good in about 75 per cent, of those who recovered. Gurlt's statistics show that in 44.3 per cent, there was ankylosis of the elbow, and in o(J.2 j)er cent, altnormal mobility, and in only 32 per cent, was the usefulness of the hand pre- served. Of course much of the after-ditliculty was due to inflannnations and snp[)urations which can now be prevented, and further experience may show that excision is a better operation than it is to-day believed to be. Wrist. — This injury, which is not very connuon and is often in asso- ciation with lesion of the lower ends of the radius and ulna above and of the second row of the carjnis and the metacarpus below, is more frequently met with on the left than on the right side. When the bullet passes antero-posteriorly, much less damage is done than when its course is from side to side. Neither the pistol ball nor the small-calibred bullet of to-day is likely to do anything like as much harm as was done by the old .45, .50, or .55 calibre soft-lead bullet, except when fired at close range. Associated injury of tendons, l>ursw, nerves, and vessels, one or all, is frequent, and much of the gravity of the lesion in former times was due to suppurative inflammation of the tendon-sheaths and of the palmar bursa, by contiguity led up along the fascial planes of the forearm. To such septic inflammations and those of the damaged bones was due almost entirely the genei'al mortality-rate of these wrist-wounds — during our late war 12.9 per cent., and in the Franco-(ierman War 12 per cent. The prognosis, therefore, at the present day must be greatly more favorable ; it certainly is so in the wounds of the joint that commonly come under care in private practice. The treatment should t)e expectant, except when the laceration is so very extensive as to necessitate primary anq)utation. Formal excision should not be done ; the mortality attending it during our war was more than twice that after conservative treatment (15.6 against 7.67 per cent.); in only 3 out of 72 cases were the results in " any way good " (Gurlt) ; of 16 German patients, but one had a good arm and hand ; eight times the ]>arts were but tolerably useful ; six times they were bad ; and once the forearm and hand were worse than useless: well might (lUrlt say that the results were " very unfavorable." Removal of the lower cny v. Bergmann and Reyher, the results of the comparatively few injuries observed in recent years have been greatly more encouraging. Protected from infection, there is no good reason why the mortality-rate shoidd not be very much lowered, especially in the injuries observed in civil practice, which, comparatively, are not severe. As with the other joints, so here : three methods of treatment are before the surgeon from which to choose — exjiectancy, amputation, excision ; and, as is true of the other joints, the knee may now in the great majority of cases be treated most satisfactorily liy the first. Selec- tion of method is not to be determined by consideration of statistics. It matters little that under conservative treatment the American mor- tality was 60.6 per cent. ; that of 1866, 43.5 ; tliat of 1870-71, 48.1 (German), 50.7 (French); that of 1877, 28.3; that after ani]>utation the death-rate in 1861-65 was 53.6 per cent, when the removal was through the lower third of the femur, 56.6 when at the knee-joint; that excision terminated fatally with us in SI. 4 ])er t'cut. of the cases, in 1864 in 85.7 percent., in"lS66 in 86.6, in 1S70-71 in 80, in 1876-77 in 100 per cent. These figures have now but an historic value; the conditions under which treatment by any method is carried out ai'e materially changed. When the injury is other tlian a very extensive one conservatism should be employed ; when the liml) evidently cannot be saved it sh;)uld be taken off. What is to be the place of excision in the future remains to be determined. The operation in civil life for pathological conditions and f >r ordinary traumatisms (in the few cases in which it has been 478 GUNSHOT WOUNDS. eni])loy('(l) has been so free from risk to life, and so satisfactory in its end-result, tliat it is quite prohalile that where the surroundings are favoral)le and the patient need not he moved, excision will at times, perhaps often, Ije done. After this operation, and especially in the cases treated expectantly, the functional value of the part will hereafter be much greater tlian heretofore, since the ankyloses will be fewer and the periarticular thickenings and adhesions decidedly less. During the course of treatment constant care nnist be taken to prevent, or at least to limit as nuich as possil)le, angular deformity. Ankle. — ^\'ounds of the foot and of the lower part of the leg involving the ankle-joint have been often observed in time of war, this articulation being the fourth of the six larger joints in order of frequency of damage, and occasionally, though rarely, such lesions are met with in civil life. The periarticular injuries, which constitute but a very small minority of the cases coming under care, are of more than ordinary interest because of the frequency of tendon-lesions, with their associated danger of suppurations ruiniing up along their sheaths, and of the later restric- tion of movements of the ankle and foot. Division of the anterior or posterior tibial artery necessitates ligation. Unless produced at short range, wounds of the bones of the joint by pistol balls or the small-calibred bullet are not ordinarily attended with such comminution as to compel operation. Quite often the frag- ments will be found so little displaced that no positive evidence of fracture can be secured by either jiressure or wai-rantable movement of the foot upon the leg, and, as a considerable amount of synovia may be disi'harged from the opened tendon-sheaths, the diagnosis must be but a probable one based upon the course of the missile. Even this may not in pistol wounds be apjjarent, because of lodgement of the bullet, which occurs in an exceptionally large number of cases as com parcfl with the lesions of other joints. The new bullet will almost certainly pass through and out. Formerly the mortality-rate was quite high (2(3 per cent, in our war), but antiseptically treated these injuries should be recovered from in very large measure. Of 24 Austrians wounded in Bosnia, every one got well, and Nimier reports from Tonkin that only 1 out of 23 cases jn'oved fatal, and that not from the injury, but from an intercurrent dysentery. Conservative treatment should be adopted unless amputation is necessitated by the great extent of damage done the bones and soft parts. By expectancy a very serviceable limb is generally secured. Care must be taken through the whole course of the treatment to keep the foot in proper jjosition, as there is a strong tendency to its over- extension and to lateral deviation. If amputation must be done, it may be at the ankle or through the lower part of the leg, according to circumstances. Chauvcl and Nimier have suggested that at times, \\hen the destruction has been of the parts about the heel and the posterior part of the sole, an osteoplastic resection (the Wladimirotf-Mikulicz operation) might well take the place of an amjiutation. Exsection of the ankle yielded very unsatisfactory results in both our own war and the Franco-German, and its death-rate was high (35.5 WOUNDS OF REGIONS. 47!) per ceut. with us, nearly three thiies that of ankle-jdint aniputatiuns, 13.43 per cent., and nearly 10 per cent, higher than that of leg ampu- tations in general, 26.02 per cent.). It is doubtful if it ever will be much favored, as most if nut all of its advantages can be secured by an intormal removal of fragments if any active interference is re<(uirc(l, and tills will not often be tiie ease. As with joint-wounds generally, liy a strict antiseptic treatment and firm immobilization not only will life be saved, but a serviceable limb secured — far better, as a rule, than any artificial leg. Occasionally, of course, here as in other articulations there may be such persistent bone-disease as will compel a late ojieration — sequestrotomy, excision, or amputation ; but just in ])roportion as an aseptic state of the wound is secured and maintained will the likelihood of this be diminished. Wounds of Regions. Head. — Injuries of the head are among the more common wounds met with in war, and of not infrequent occurrence in civil life. They are either of the scalp or of the cranium — many more of the former than of the latter as they come under treatment (7739 against 4350 in our late war). But it must be remembered that one-half of these head-lesions have proved fatal on the field, and it may reasonably be expected that a much larger number will be killed by the new bullet, because of its greatly increased velocity. The scalp-wounds are either contusions (rarely met with), lacerations, perforations, or penetrations with lodgement of the ball. Injuries of the latter class have been but seldom seen in military service, and are not likely to be produced by the modern missile — never except when it is very near the end of its flight. Pistol lialls, especially those of small calibre, are often buried in the tissues, frecpiently nuich flattened. Com- monly they can be easily felt or their situation determined by ])robing. When in the temporal muscle their location may be indicated only by pain upon movement of the lower jaw and upon pressure above the zygoma. Laceration of a temporal or occipital artery may give rise to considerable hemorrhage and, as is the case in other traumatisms of the scalp, the development of a condition simulating depressed fracture. Such blood-accumulation, if not rajiidly absorbed, should be aspirated or cut down upon and washed out with an antiseptic solution. Properly treated, these injuries may be expected to be readily recovered from, though heretofore the mortality-rate has been from 6 per cent, to nearly 30 \)er cent, in different wars, the fatality being consequent upon septic disease of one form or another. The ordinary antiseptic treatment should be thoroughly carried out, the l)ullet if lodged being removed when its location has been determined. The cranial lesions are those of either contusion, penetration, or jier- foration. Contusions, which were about 7.5 per cent, of these lesions as met with during our war, are produced by the glancing imjxict of a rapidly-moving missile or the direct blow of a shot having but little momentum. They jirobably will not be caused by the new bullet, as almost certaiidy it will fracture the bone when it strikes it. As is the case with like injuries of other bones, the damage done may be slight. 480 GUNfSHOT WOUNDS. giviiiij rise to no syniptonis ; or iiiorc severe, causing limited extravasa- tions, after a time absorbed, or superiicial necrosis and exfoliation ; or sutttciently great to cause a sej)aration of the outer table over a small surface ; or, but very rarely, to destroy the vitality of the entire thickness of the bone. The inner table may he fractured, with more or less dis- placement of fragments toward the interior of the skull, but this is of infrequent occurrence (Fig. 34). Gunshot contusion of cranium, witlx fracture of internal table, exterior and interior view (A. M. M., Spec. 2313). The wound becoming infected, inflammation of the diploic veins is very likely to follow, with resulting pvieniia with ab.sce.sses in the lung or liver, or a sujjpurative meningitis. Ivarcly is the " putfy tumor" of Pott present. It is to such infection that the fatality of the.se contused injuries has been chiefly due, the percentage of which reached 16.8 in our war, and the prevention of such septic conditions will ensure recovery in the great majority of the cases — in all, we may expect, except tho.sc in which fragments of the inner table are driven down or the associated brain- concussion, laceration, and hemorrhage are of themselves mortal. The wound must be thoroughly cleansed, an anti.septic dressing applied, and the patient ke])t (juiet. If eonstitntii^nal sym]itoms of decided severity arise, indicating infective inflammation of bone or meninges, the contused area should be freely exj)osed and trephining done. The operation as now conducted will not add to the gravity of the case, whatever may have been true of it formerly, and it will make it possible to remove any detached pieces of the internal table, to disin- fect, and to secure drainage. Sometimes — and, iinfiDrtiinatcly, not so very rarely — no symjitoms of moment are jiresent for many days, when suddenly violent headache is experienced, followed by eonvulsions, coma, and death from cerebral abscess. For three months or more, the huntlred-day period of Pare, the patient is exposed to this danger. WOUNDS OF REGIONS. 481 Except in the mildest cases, such as may readily escape detection, and frequently do so, there is usually, after recovery from the immediate effects of the wound, and it may be for a long time, more or less head- ache, often associated with dizziness, intolerance of light and sound, nausea, and vomiting. Epilejjsy, paralysis, and mental irritability have in many cases been produced, as in similar contusions from violence other than gunshot. The prognosis, therefore, is more grave than the mortality-rate would indicate. Occasionally, though not often, bone- atroi)hy follows, exceedingly seldom hypertrophy. Tiie fractures produced by gunshot are graver lesions than those con- sequent upon other traumatisms, because of the greater intensity of the vulnerating force. Association of brain-injury is more constant and the visceral damage much more extensive ; and this whatever the form of fracture, which varies from a linear break to a shattering of several, it may be all, of the bones of the skull. This shattering in bullet-injuries is due, as in other fractures of the head, to fissures starting from the original wounds, to vibrations conducted along the cranial tiiickenings from vault to btise or from the occipital bone forward, and also, and much more largely, to the liydraulic pressure set in action Ijy tiie ball as it passes through the brain. Numerous experiments, beginning with those of Busch and Kocher, have proved beyond question that there is such pressure in gunshot wounds of semi-fluid tissues, that it is proportionate to the fluidity, and that it is most strongly manifested in the brain, whicii is structurally fitted to develoj) it and is confined within rigid ^valls that will in the highest degree display the effects of it. Within the zone of explosive action, which with respect to tiie head extends, using the modern arm, to 600 or 800, even to 1000, yards, this hydrodynamic pressui'e produces ■\vide destruction — so wide that life is very unlikely to be preserved. At close range brain and bone may be lilown into fragments — less likely to be witii the small- tlian the large-calibred bullet. Wagner of the Austrian army, having observed nine suicidal cases among soldiers in which death was immediate, reports that there was less destruction than in similar cases previously seen in which a large ball was used ; the greater part of the brain was intact, there was less crushing of bone and less fissuring, and the greatest damage was about the wound of exit. Only exception- ally does tlie hydraulic pressure cause fracture of the base, and then in the great majority of the cases it is the ethmoid or the orbital surfaces of the frontal that are broken, though it is possible, doubtless, that tlie tliin plate of the temporal covering the internal ear may yield. Pistol balls do not ordinarily have sufficient momentum to develop an explosive action, but womids jiroduced by tliem at short range at times show splintering of the orbital plates, even witii depression toward the orl)ital cavity. jMucIi interest in sucli injuries has been taken since the death of President Lin- coln, and a numbe'" of cases quite similar to his have been put on record. At the autopsy of the President the bullet, which had entered througii the occipital bone, was found to have passed forward in the brain and lodged just above the anterior ])ortion of the left corpus striatum. Botii orbital plates were comminuted, tiie fragments being forced inward ; tiio dura mater, however, was uninjured. The crusliiuffs caused bv larsre shot and bv sliell-fraffments, and the bullet wounds and those made by charges of small shot at close range Vol. r.— 31 482 GUNSHOT WOUNDS. which are immediately or very quickly fatal, have no practical interest. It is in these cases, iu which death occurs at once, that there is observed at times a stiifening of the body in the position had at the moment of injury. In a case in Northern New Ham})shire some years since, in which tlie top of the head was blown off' by a load of shot from a gun but a few feet away, the body of the woman was found sit- ting in a chair before the fire in the attitude of knitting, with the needles which she had been using still held in her hands. This "traumatic cataleptic rigidity," though met witli in those shot through the chest and abdomen, is usually associated with cranial injuries. As in other bones, there may be in the skull groovings, fissurings, penetrations, and perforations. The groovings are usually associated with fissures, which may affect only the external table, but are gene- rally found to extend through the entire thickness of the bone — always, perhaps, excejit when it is " the supraorbital ridge, the zygoma, or the mastoid or occipital protuberance that has Ijcen struck, or the lesion is caused by a sharp fragment of shell " (Otis). In individuals who have passed the age of puberty the outer wall of the frontal sinus may be broken in without accompanying injury of the inner wall, rarely hap- pening, however, excei)t when it is a pistol ball that is the vulnerating body, the shot often lodging in tlie sinus, from which it may be readily extracted. In children penetration in this region almost certainly means piercing of the entire thickness of the skull and wound of the brain. When both tables of a cranial bone are broken from without the damage to the internal is usually decidedly greater than that to the external table, the more so as the fracture of the latter is circumscribed. Such injury is in accordance with " Teevan's law," that fracture always commences in the line of extension, not that of compression. When the vulnerat^ ing force acts from within, the splintering is greatest in the outer table, which then might be named the " vitreous " one, cases of injury of this kind being observed in suicidal and other shots through the mouth and face, when the ball, ranging upward, emerges through the vertex. In the exit wound of a perforation there will be noticed the same excess of splintering in the outer table. The elasticity of the skull causes at times a return nearly to its original position of a fragment at first sufficiently depressed to permit of the entrance of a bullet. In a few cases pene- tration has been indicated only by the presence of hair in the fissure, as in those reported by Assistant Surgeon Howard of our army and by Koenig ; ' and it is possible, as in a case of v. Bergmann's, that a piece of a projectile may upon autoj>sy be found in the brain, and nothing but a mere crack be discovered through which it could have entered. When the momentum of the ball is not great the fracture may be confined almost entirely to the surface struck, slight depression occur- ring or a jiiece of the skull of about the diameter of the missile being driven in below the general level of the internal table. Sucli a typical punctured fracture is not likely to be observed except when the ball is small, fired usually from a pistol or a toy rifle. In cases of more ^ In a case reported by Matthew, from the Crimean War, hair was found in a fissure of the external table only. WOUXDS OF REGIONS. 483 extensive, but still not great, splintering the lesion is commonly confined to the bone struck or passes but little beyond it. Penetrating and perforating wounds are always very grave injuries. The bi'aiu is seriously damaged in those wounds of this class not speedily causing death from shock and hemorrhage, and in cases of penetration there are the added dangers conscijut'nt upon the presence of bone- fragments and the missile. The shot may jiass antero-posteriorly, laterally, or obliquely at any angle, rarely from below upward, and almost never directly from above downward, except when produced by bursting shells. Basal frac- tures, which are not very common, are met with as continuations of those of the vault, en- in wounds through the neck or face, largely suicidal. That a cranial fracture (other than of the internal table alone, which is always conjectural) has been received is usually readily determined by palpation, by inspection, by jirobing, or by percussion, which may give the " cracked-pot " sound. The course of a ball which has not passed through is often very uncertain, the missile frequently striking the oppo- site wall of the skull and being deflected, it may be at a large angle. To trace it a probe must be employed. If metallic (one made of aluminum is far the best), it should be used with ligiit hand, the head being inclined and the instrument allowed to fall by its own weight, since it is very easy to push it through the soft cerebral mass. Oftentimes a moderately firm, elastic one, such as an urethral bougie, will be preferable. Always the instrument must be surgically clean, and it should be used only after careful disinfection of the external wound and the pai'ts about. It is in these injuries that the telephonic probe has been found of service. If probing shows that the track has passed across the head, but the missile is not detected, a button of bone should be removed over the end of the canal, and search be made back along the track from that side or for the opening of the new canal made after deflection. As in the memorable case reported by Fluhrer in 1884, a second trephining may have to be done to find the course of the shot yet further deflected. Before any exploration of the track is made the opposite side of the head should be carefully examined, as it may be that the ball lies under the skin or is in the bone, and is forcing it out in such way as to be easily felt or to be indicated by pain on pressure. If the missile cannot be found after reasonable careful search — and very often this is the case — it will have to be left. Occa- sionally cerel^ral symptoms (paralysis or disturbances of smell, sight, or hearing) mmII indicate, if not the location of the ball, at least the course that it has taken ; but these symptoms are less reliable than they other- wise would be because of the widespread injury of the brain outside of the immediate track of the shot. The symptoms of basal fracture are the same as those of similar injury from ordinary violence. The development of complicating septic ioflanmiations is indicated by the usual symptoms of such affections. As is the case in the ordinary tnuunatisms of civil life, meningeal suppurations are accompanied with decided elevation of temperature ; those of the brain are not, and no paralysis occurs in meningitis at the base. Fungus cerebri, misnamed hernia, has been met with (at least sixty-one times in our war), and must be so in the future in cases that have become infected. The prognosis is always grave. As has been stated, one-half of those wounded in action never come under care, and of the other half 484 GUNSHOT WOUNDS. 73.8 per cent, died in the Crinioa, 4(3.1 in 1859, 59.2 in 1861-65, 51.3 in 1870-71. Of perforating and penetrating wounds in our war, 80 and 85 per cent, proved mortal. Balls lodged in tiie frontal lobes have Ijeen l)etter tolerated tlian those elsewhere. Though much of tlie fatality heretofore has been because of septic complications, nuicli of it has l)eeii from causes, chictiy shock and hemorrhage, that no treatment c((uld have jirevented. Of the 91 pistol-shot wounds occurring in recent years, tabulated by Brad- ford, 51 died (50 per cent.), and of these 39 (42.86 per cent.) died within a few days, 19 (21 per cent.) within a few hours; that is, 76.47 and 37.21 ])er cent, of all who died. As I'epresenting the probal)le death-rate under present methods of treatment and in a class of cases more likely to recover than those in whicli the damage lias been done by an army bullet, the pistol-ball injuries studied by Bradford are very instructive. Of 25 cases shot in the temple, 16 (64 per cent.) died ; of 5 in which the ball entered through the ear, all died ; when the bullet entered in front of the plane of the external auditory meatus, 59 cases (57.7 per cent.) died ; when in such plane or posterior to it, 32 eases (59.4 per cent.) died ; the mortality when the ball was removed was 33-^- per cent., Aviien it was left, 54 per cent.; of 25 cases treated expectantly, 52 per cent. died. Lesions of the anterior part of the cerebrum were thought by Guthrie to be more grave than those of the posterior, and so Bradford found them in a percentage of 1.7. Wiiarton's table, however, shows a much heavier deatli-rate in Mounds through the occipital bone, and in the Crimea the wounds in the anterior half of the head proved to be less dangerous. Wounds from side to side, especially those through the ear or very close to it, are much more serious than antero-posterior ones. In part this may be due to their being largely suicidal injuries, and therefore received at veiy close range, the mental condition, moreo\"er, having of itself in these wounds, as in those of otlier regions, a depressing influence, decidedly increasing the risk to life. Lesions of the cerebellum almost always prove quickly fatal. Meningeal inflammation and brain- abscesses are excessively dangerous, as tliey always are, though by open- ing up the inflamed area, if it is a limited one, evacuating the pus, and securing proper drainage, relief at times may be afforded. Fungus cerebri is very apt to terminate fatally, esjiecially Mhen actively treated ; 82 per cent, of the cases reported in 1861-65 died — a mortality-rate, however, much greater than in all probability will occur hereafter. But death in a few days or a few weeks is not the only bad result of these cranial fractures. Injury of the optic nerves causes blindness — of the auditory, deafness. Necrosis of bone, rarely caries, was formerly very common, and must always occur at times desi)ite the most rigorous anti- sepsis. Cerebral disturbances of all kinds have been noticed again and again, and in greater or less measure are almost certain to come on. Epilepsy, paralyses, headaches, amnesias, changes in temper and in habits, imbecility, insanity, diabetes, each has often appeared, and tliat, not seklom, years after apparent recovery. When the ball remains in the head it ordinarily does not become encapsulated, but slowly moves under the influence of gravity, and because of tlie pressure exerted by it and the organic changes induced by its irritating action the almost absolute certainty is that some form of brain-trouble will at some time manifest itself. WOUNDS OF BEGIONS. 485 The treatment of these lesions has reference to the wound itself and to the complications that may arise. As has been already stated, much of the fatality is consequent upon shock and primary hemorrhage, for the relief of the former of which, wlien severe, nothing- can be done, and but little for the latter, the cases occurring in military practice and living long enougli to come under care being almost certainly hopeless. In the wounds of civil life, if the bleeding is from an external vessel, com])res- sion may arrest it, but, as a rule, ligation should be done ; and such should be the practice when a meningeal artery (usually the middle) has been injured. It may doubtless at times be found advantageous to introduce a sterilized gauze plug wlien the hemorrhage is from the track of the bullet in tlie brain ; and in certain exceptional cases periiaps, when the compression-symptoms indicate a progressive bleeding, ligation of the carotid may be of service. The wound being from pistol shot, the scalp should be shaved, the damaged area antiseptically cleaned, and if penetration has occurred a button of bone including the entrance wound removed by trephining ; in other words, the injury should be treated as though it was an ordinary punctured fracture of the skull. Removal of the bone does not add to the gravity of the lesion, and permits of the taking away of any frag- ments that may be present at the orifice and the more ready examination of the track within. Careful search for tlie ball and deejily located bone- splinters should then be made, and if found they should be removed with a forceps no larger- than is absolutely recpiired. But in searcliing and extracting care must be taken to do as little violence as possible to the brain already seriously injured. When the foreign bodies have been taken out, or if the bullet is not found, or if found is at such dejith as to make it unwise to attempt its removal, the blood-clots and devitalized tissue in the canal (which is always of a diameter much larger than that of the missile) should be washed out very carefully or scraped away, a drainage-tube introduct'd, and an antiseptic iiead dressing applied. If the ball has passed through and out, the exit wound also may be tre- phined, or only its detached fragments removed to such extent as will allow of free drainage. Here the external table is certainly as much, probably more, splintered than tiie internal, and the ends of partially separated sequestra are pushed away from the meninges and brain instead of toward them. The securing of tiiorough drainage is of the higiiest importance, for increase of pressure upon the brain from extrav- asated blood adds much to the gravity of the wound. If, though the ball has not passed out, it can be located under the skin or in the bone, it should l)e removed and the injiny thus converted into a perforating one. Bradfiird's statistics indicate tiiat cases in which the lodged ball is removed ai'ter trejiliining are more likely to recover than those of per- foration, probal)ly l)ecause in the great majority of such cases tiie bullet has not penetrated deeply and the brain has been less seriously damaged. These statistics furtiier show that if the bullet remains in the head the termination of the case is about tlie same whether any operative interfer- ence is made or the case is treated expectantly. When tlie wound is produced by one of the new rifle bullets, if the missile enters tiie cranial cavity it will, except at an extreme range, pass through, and there will be no occasion for searching for it or extracting it. 486 GUNSHOT WOUyoS. If the lesion is not one of peneti'ation, the fracture should be treated on the same general principles as apply to a similar one due to an ordinary trauma, trephining heing done or fragments Ijcing removed in a more informal way whenever there is depression or any decided cunnninution. The adoption of aseptic; and antiseptic methods of operating and dress- ing has greatly changed the status of these procedures, which as now carried out do not, or but in slight degree, expose to the danger of the lighting up of septic inflammation, the development of which in former times was so general and so fatal. Any discovered clot under the skull or under the dura should be removed by irrigation or by the finger or an instrument. The secondary complications that may arise and that demand treats ment are the infective diseases of the meninges and brain, with result- ing ditfused or circumscribed collections of j)ns, and secondary hemor- rhage. Meningitis and nieningo-encephalitis, which ordinarily come on from the third to the sixth day, but are often deferred for as many weeks, and which present no features other than those met M-ith in cases of trau- matisms not produced by gunshot, are to be treated in the same M'ay as in the latter, no treatment commonly being of much avail. They are to be prevented, if possible, by the adoption of a rigidh^ antisejjtic wound- treatment, and without doubt it -will be possible to prevent them in a considerable proportion of the cases in civil life. When the sympttmis present indicate the formation of cerebral abscess — and these, unfortunately, do not ordinarily show themselves until rupture has taken place into a lateral ventricle or the pressure exerted upon the Ijrain is great — there should be an active interference at once. Trephining, if necessary, should be done, and exploration made by the use of an aseptic director, or, better, an aspirator needle, or such exploration be made through the already exj)osed meninges or cortical substance. There should be no hesitancy in carrying the needle deeply, and, if required, in various directions, in the hope of finding the abscess, since the exploration does not materially, if at all, increase the gravity of the situation, and only in ])romj)t evacuation of tlie pus with the securing of after free drainage is there any chance (if saving life. Occa- sionally such fortunate result will folloAV, but ordinarily the case soon terminates fatally. Secondary hemorrhage, almost invariably due to septic changes in and about the wound, should be treated by ligation of the bleeding vessel, or, if this cannot be efi^ected, of the main trunk, the exti'rnal or common cai'otid. The mortality attending the latter operation, formerly great (68.75 per cent, of the cases I'eported during the wars of 1861-65 and 1870-71, 11 out of 16 patients dying), should hereafter be less in pro- portion as the fatal result was directly due to the ligation, though ex- haustion from previous loss of blood, cerebral softening, or accompany- ing septicaemia or pyaemia must still carry off many of those operated upon. Ligation of the external carotid \\hen the bleeding is from one of its branches should be preferi-ed to that of the common ti'unk, as all recent experience has shown that it is a much safer operation (as 11 to 78), and at the same time more effective in controlling the hemorrhage. Fungus cerebri, if it forms, should be treated expectantly by moderate compression. Operations on such mass (ligation, excision, injection, WOUNDS OF EEGIOyS. 487 cauterization) have not nsually proved of service, the mortality attending tiieni in 1861-()5 being 75. S per cent. In the treatment of basal fractures in which there is discharge of blood or serum from the nose, mouth, or ear, the nasal cavity, the naso- pharynx, and the external auditory canal are to be thoroughly disinfected aud plugged with sterilized or antiseptic gauze. Face. — Wounds of the face are perhaps about 4 per cent, of those received in action (3.83 ])er cent, in our war), and are not seldom met with in civil life, wiiere they are caused l)y small sliot single or in mass, by pistol balls, and, in a \'ery few cases, by pieces of caps or fragments of a gun that has burst. They are of interest chiefly because of the occa- sional occurrence of dangerous hemorrhage, primary or secondary, or of the not infrecpient extensive lacerations that they produce and the re- sulting deformity, often very disfiguring. Their mortality-rate has not been great — 4 to 7 per cent, in different wars, and this chicily in the cases of fracture, flesh wounds rarely causing death (in 1.5 per cent, only of the nearly five thousand (4914) cases tabulated by Otis). Even this rate may be expected to be much lowered hereafter in degree pro- portionate to protection against sepsis. Flesli wounds made by pistol balls firetl from a distance or by small sliot are attended with but little destruction of tissue, and are quickly recovered from, the resulting scar- rino; beino; usually but sliaht. Occasionally the bullet or charge of small shot seriously damages the eyelids, the lips, or the soft pai'ts of the chin, witii later cicatricial contraction that may necessitate operative treatment. Generally, howevei", these graver lesions are associated with injuries of bone, which occur in about one-third of the cases. Any bone may be injured, but most connnonly it is the inferior maxilla, tiie fracture of which much resembles, as respects s])liutering, that of a long bone. The superior maxilla was frequently much connninuted by the old large-cal- ibred Ijullet, though tlie fragments were generally adherent; with the new bullet in the middle ranges much less splintering may be expected to be produced. Pistol balls crush it but little, as a rule, except when tiie wcajjon is disciiarged at very short distance, and not always then. The cavities, orbital, nasal, and oral, are often penetratetl or perforated, the shot at times doing no direct damage to the eye or tongue. Tiieir penetration may take place without any injury to bone. A bullet may pass out through the mouth or the anterior nares, not wounding, or but slightly wounding, the lijis or tiie nose. In a case reported from the Franco-Gcrmau War a ball entered through the anterior nares, struck the posterior pharyngeal wall, and, reboundilig, made exit through the mouth. When tiie missile passes antero-posteriorly the brain, spine, or great vessels of the neck are often damaged, though not seldom in suicidal wounds through the mouth the brain is uniniured, backward jerking of the liead causing the ball to take an upward course in front of the cranial cavity. When the bullet enters the lirain through the orbit or tlie mouth, death is almost sure to follow from the primary injury or secondary septic inflammation. Passing transversely, one or more of the larger blood- vessels of the face or upper part of the neck may be wounded, and it is the likelihood of the occurrence of sucii lesion that renders injuries of the bodv of the lower jaw of grave import. Ijodgement of the ball, especially in pistol shots, often occurs, such lodgement being in bone or in one of 488 OUNSIIOT wouyDS. the cavities — the frontal sinus, the antrum, the nasal fossa, or the orl)ital cavity. In many eases, after havint;' remained in the face for a lonjj time, the bullet has heen s])()ntaiieously extruded, or, haviiiji; uleeratelicated by tracheal or oesophageal injury, is of interest only because of the bleeding that occurs — bleeding to be controlled by ligation of the vessel or by suturing, plug- ging, or cauterizing the wound. Spine. — In these wounds a vertebra may be contused ; one or other of its component parts, body or posterior arch, fractured ; or the canal opened, with associated lesion of the meninges or the cord, the latter being much the more se\'cre injury. These wounds are produced by mis- siles (bullets or shell-fragments) striking the back, passing from side to side, and injuring the spine in its course, or coming from in t\x)nt, aflect- ing the vertebra only after having wounded the jiarts anterior in the neck, chest, or abdomen. It is to these last-mentioned complications that much of the great gravity of these wounds is to be attributed. As is true of head-injuries, this gravity is in but slight measure due to any existing bone-lesion, being chiefly due to the damage done the cord or its coverings, to concussion or compression from l)lood-elot or jius- collection, to organic changes in the meninges or the nerve-tissue, or to destruction of such tissue. Shock is always great, even to the extent of producing instantaneous death with following traumatic cataleptic rigidity ; and the same physical conditions that favor explosive action WOUNDS OF REGIONS. 493 in the head are here present — ahimdance of fluid and a rigid bony envelope. The symptoms are those of any and every injury of the oord, though more marked, as a rule, than after other traumatisms. They are im- pairment of the motions of the back ; partial or complete paralvses of muscles of the trunk or extremities ; anesthesias and hyperfesthesias ; peculiar and severe pains of a girdling, gnawing, tearing, or burning cha- racter ; disturbances of respiration, of circulation, of defecation, of mic- turition ; neurotic gangrenes, often of rapid development, in parts pressed upon, as on the back, over the trochanters or heel, or at the distal ex- tremities of the limbs from defective blood-supply, such as not seldom also follow injuries of the nerve-trunks. Sometimes, MJien there has been penetration of the canal, this fact will be evidenced by escape of cerebro-spinal fluid ; but this symptom is by no means a constant one, and when present only shows that the theca has been opened, not that the medulla has certainly been damaged. Contusions of the spine usually cause but temporary disturbance of motion or sensation, occasionally a meningo-myelitis ; such inflammation, however, is lighted up less often than after similar injuries of the cranial bones. These effects, aside from those of infective character, are, as a rule, quickly recovered from with- out serious after-consequences, though at times stiffness of the back or some paralysis of an extremity remains, and in rare instances necrosis takes place, as in a case reported by Keen, in which there was sponta- neously discharged, after about three months, " nearly the entire body of the third cervical vertebra, including the anterior half of the transverse process and the vertebral foramen." The fractures that come under care are largely those of the spinous and transverse processes. Those of the body are nuich graver lesions, and that whether the bone-lesion be one of groo\-ing, of penetration with lodgement of the ball, or of perforation. In them the bone is often much fissured. The lower in the column the fracture, the less severe it is likely to be, the mortality-rate, as stated in the Medical and Surffical History of our war, being 70 per cent, in the cervical, 63.5 in the dorsal, and 45.5 in the lumbar regions. Hemorrhages outside of the dura, within the theca, or in the sub- stance of the medulla, especially the first two, are very generally asso- ciated with spinal injuries, causing severe pain, often shooting around the body and serving to indicate the location of the injury. Such pain, when the extravasation is l)ut slight, ordinarily subsides in a short time, returning again temporarily when the period of reaction sets in, and then, as absorption takes place, more or less rapidly passing aM'ay, to- gether with the paralytic condition produced by the clot. When the clot is a large one, its pressure-effects are correspondingly great, and there is generally an associated infective myelitis. Compression of the cord is produced also by a lodged ball, or, more often, by depressed bone- fragments. As in brain lesions, there is here always more or less con- cussion of the medulla, and with the jarring there is usually associated contusion of greater or less amount, thougii the cord is more protected by the " water-bed " in which it rests than is the brain. Such contusion with its associated laceration varies from that which is quickly recovered from, without any organic change being produced, to that which is destruc- 494 OUNSHOT WOUNDS. tive to a part of tlio coic). Tlip extensive tearings and crushings, however, are cliiefly due in tlic action of eitlier hail, l)one-fragment, or Ijotii. I'lie prognosis in military jjraetice lias always been very grave, one- half, two-thirds, three-quarters, nine-tenths of the cases coming under treatment dying, the most of them within a few days. In civil life there is more chance of recovery, the injury, as a rule, being less severe and the patients coming sooner under care, and that after com])aratively little mov- ing. Wlien the canal has l)een opened — by j)cnetration or by perforation, it matters little wliieli — the danger is very much greater than in other cases because of the compression or laceration of the medulla ; tlie wound in those who have recovered heretofore liaving been almost always of the sacral or lower lumbar vertebra' ; that is, below the end of the cord proper. Antisejitic treatment may be expected to lessen somewhat this mortality-rate, l3ut in all proljability its beneficial eiiect will not be very great, as in many cases it will be impossible to secure asepticity ; and sepsis is l)y no means the chief cause of death, which so oiten must result from shock, hemorrhage, or associated lesions of imjwrtant viscera. When there has been no injury of the cord or theca, other than perhaps a limited extravasation of blood outside the sheath or a slight concussion of the medulla, recovery may take place, and that with little after-dis- turljance, organic or functional, this being especially true of wounds of the processes, particularl)- the spinous. Kareh', however, is the wounded man so fortunate. Almost certainly there will later be stiffness and weak- ness of the back, impairment of function in arm or leg, muscular atrophies frequently with e(jntractures, urinary troubles of greater or less severity, neuralgias, ataxias, mental disturbances, one or more ; in other words, the jirimary lesion, if it does not kill, may be expected to be followed by ciironic inflammations and scleroses that cannot but be greatly disabling, the effects of which may not perhaps be manifested for years. When a nerve has been damaged close to its intervertebral foramen, the parts to which it is suj>plied will be found to be seriously affected as respects both sensation and motion. Treatment, aside from that to protect against infection and that of the ordinary complications of spinal injuries in general, has reference to the removal of foreign bodies and the securing of rest to the injured part. When the bullet has been located and its extraction is feasible, it should be taken away and the wound cleared of such non-adherent bone-fragments as can be found. Sometimes the extraction of the ball has been followed by hemorrhage sufficient to necessitate plugging. Karely has ligation of an artery been required. Recently nnich attention has been directed to the performance of laminectomy for the relief of pressure, whether caused by a displaced fragment, by a blood-clot, or, later, by an overgrowth of bone. In the present state of surgical jiractice a jiroperly-conducted operation of this sort does not mateinally add to the dangers of the ease, and permits of a determination of the condition of the theca and cord, the removal of whatever may be pressing upon the medulla, the extrac- tion sometimes of a l^all lodged in the body of the vertebra, and the thorough cleansing of the wound. To open up the canal a trephine may- be employed, or, better, the chisel and the cutting forceps. In gunshot even more than in other fractures of the spine, operative interference promises to be of veiT much service, freed as the operation now is of the WOUNDS OF liEGIONS. 495 greater part of the danger of lighting uj) a septic raeningo-myclitis. If it does no good, it will ordinarily do no harm. The cases in which it iias been done are as yet too few to permit of tiieir statistics being regarded as establishing a rule of conduct ; but mere numbers of reported deaths and recoveries ouuht never to be so regarded. Sound reasonina- and observa- o o o tion of the analogous ordinary accidents of civil life certainly now justify — more, authorize — the operation in any case in which there is not such associated injury of vessel or organ as makes recovery under any circum- stances imlikely. The coexistence of any serious visceral lesion contra- indicates any operative interference. Whether an operation is done or not, the spine should be immobilized and rest as absolute as possible secured to the patient. Chest. — A considerable proportion of the wounded in action (6, 8, even 10 per cent, of those receiving treatment during a given war, and one-third to one-half of those killed outright) have been found to have been shot in the chest. In civil life such injury has been frequent, ])i'o- duced either accidentally or with intention. The wound may be of the parietes or involve the cavity by jienetration or perforation, and if of the chest-wall may be associated with fracture (costal, sternal, vertebral, clavic- ular, or scapular) or with lesion of an important vessel or nerve. When there is no such complication a non-penetrating wound is usually one of little moment — simply a flesh wound, to be treatecrforating lesions. Among wounds received in action hereafter rarely will there be found one of the former, the new bullet almost certainly passing through and out, and in the large majority of pistol-shot wounds the ball is now found to jierforate either comj)letely or so far as the thoracic cavity is concerned. The result is and will be that a larger percentage of the cases not quickly fatal do and \vill get well, freed as they must be more or less completely from the dangers of suppurations, fistulte, and septic infection. Prompt healing characterized the cases observed by Stitt in the late Chilian AVar. Even when the ball has lodged, if let alone it commonly does no harm when an aseptic or antiseptic state of the wound is secured. Never again, probably, will the death-i'ate of the cases treated reach 80 or 90 per cent., as in the Crimea, or 65 per cent., as with us, or 68 per cent., as in 1870-71. Very much more than half of the pistol-shot cases in our ho.spitals recover ; indeed, death is exceptional in those not almost necessarily fatal from the nature of the injury. Wounds of both lungs, the shot having passed from side to side or very obliquely antero-i:)Osteriorly, are and nuist be grave lesions, because of shock, hemorrhage, or developed septic inflammations, but because of the smaller smoother bullet and protection from sepsis they are now, and will be in the future, less frequently than heretofore followed by death. Multiple wounds are but little if any more dangerous because of their number, their gravity being determined by the character of the individual injuries. That penetration has occurred may or may not be clearly ap])arent, the only positive proof of lung-wound being afforded by ])rotrnsion of a part of the organ (primary hernia), the regular to-and-fro j)assage of air synchronously with the respiratory movements (traumatopncca), actual inspection of the lung through the wound, or upon digital exploration. The evidence from neither sight nor touch is obtainable in the ordinary bullet wounds of to-day, and the hernia and peculiar breathing only very WOUNDS OF REGIONS. 497 rarely are to be observed. Probing should not be resorted to, as if the diagnosis cannot be otherwise made it is not necessary to establish it, and much harm may easily be done by such exploration. ^Vhen there is present a wound of exit as well as one of entrance, and the line joining them passes through the cavity, it may now be taken for granted that there has been penetration, for deflection of such Ijidlets as are in use (i)ther than perhaps the smallest) will not occur. Emphysema also might be regarded as proof positive were it not for the fact that in a limited degree it may be present in a non-penetrating injury, air sucked in from without being, because of the valvular character of the track, prevented from entirely escaping upon expiration. The ratit>nal symptoms, in general, ai'e pain, difficult, or more prop- erly constrained, breathing, spitting of blood, and cough ; there being in addition, when air or blood in quantity is in the pleural sac, compression of the lung on one side with tliminution or arrestation of the chest move- ments on that side, increased resonance on jiercussion when air, dimin- ished Avhen blood, is present, with shock or collapse symptoms in greater or less degree. Penetration may occur without injury to any part other than the pleura, the ball cutting it in passing across the chest between two ribs — an accident )irol:iably of very infrequent occurrence, very luilikely to be recognized, and without interest except such as attaches to the non-penetrating wounds. Complicating these wounds are hemorrhages, lodgement of foreign bodies, fractures, accunudations of air or j>us in the plcui'a or (jf pus in the mediastinum, and associated lesions of the spine or of the parts below the diaphragm. The bleedings may be cither external or into the chest- cavity, the former when other than slight being ordinarily from the large arteries or veins in the neck or axilla, the latter from the intercostals, or, much less frequently, the internal mammary artery, from the great vessels in the chest, or from the heart, those from the last two sources commonly causing death so promptly that they need not now be consid- ered. Bleeding from the lung-tissue is ordinarily not very abundant, especially when the wound is toward the periphery of the organ, though to it is to be attributed the bloody expectoration which is so frequently observed during the tirst few days, and in some cases the produced hemo- thorax — a complication, so far as it comes under treatment, commonly due, ho^vever, to injury of the intercostals. Tlie hemorrhages from the axillary or subclavian may be either primary or secondary, in the former case the blood being discharged externally or infiltrating the surrounding tissues, forming a fiilse aneurism. In a few cases late opening of the subclavian has been consequent upon the fretting away of the arterial wall by the rough end of a clavicle-fragment. The lodged foreign bodies have usually been bullets, which have become encysted, remaining at times for years without doing any harm, or have been coughed up or by ulceration worked tiicir way into tiic oesophagus to be later discliarged at stool (occurrences that have been very infrequent), or have dropped into the pleural cavity to remain or to be removed after ojjening of an enqiycma. No such lodgement may now be looked for cxce]>t in a small minority of the pistol-shot wounds, and in these cases encaj>snlation may l)e expected very generally to I'ollow. Fractures are of much less importance as complications than hereto- VoL. I.— 32 498 GUNSHOT WOUNDS. Cove, except wlicii frnirnK'nts of tlie broken l)one (coninioiily a rib) are detached and driven into tlie bnijj;, and even tlien tlie resulting danger is decidedly less than formerly. Protected from the development of septic intlammations, neither a costal nor a sca])ular fracture produced by an outgoing ball adds materially to the gravity of the case. Heretofore frac- tnre of both scapulfe has been largely a fatal injury, but will be so here- after only as the result of associated lesion of the spine or of important structures in front of it. Pneumothorax is but little likely to follow \vounds made by the mod- ern small-calibred ball, and is very rarely seen to any serious extent after pistol-shot injuries. Pus-collections in the lung, the mediastinum, or the pleural sac must also be much less frequent than before, though no antiseptic treatment can be pursued that will prevent such infection of the blood-clot in tlie pleural cavity as is j)roduced by organisms coming in through the air- passages, or overcome the .septic influences of discharges into the medias- tinum from an opened oe.sophagus — a complication of extreme rarity, yet which may be present. Associated wound of the abdomen, as might be expected, is one of the graver com])lications, about three-quarters of the cases terminating fatally, but fortunately is not very common, having been observed in less than 1.5 per cent, of the chest- wounds reported by Otis. In civil life the frequency is greater, but the mortality less. In a limited number of cases, though the patient does not die, the recovery is imperfect, the lung being contracted and bound down by adhesions or being the seat of chronic inflammations or tubercular de- posits ; fistulie may be persistent ; lateral curvatures of the spine may be induced, etc. The treatment of these penetrating wounds consists chiefly in secur- ing rest. Shock, if severe, may necessitate the administration of ether or strychnia by the mouth or hypodermically, alcoholic stimulants being avoided as much as possible. No search for a lodged liall should be made ; if it can be felt in the chest-wall, it may be removed at once or left undisturbed for some days until the track may have so far healed as to ensure jDrotection against any possible infection of its deeper part. Any bleeding vessel that is in sight should be tied. The wound or wounds should be thoroughly cleansed and closed with sterilized gauze, and then the chest immobilized as far as practicable and rest as abso- lute as possible maintained. Lately it has been advised to efl'ect immobilization by the ajiplication of the plaster-of-Paris jacket, and a series of twenty successful cases of pistol wounds thus treated has been reported from the City Hospital of St. Louis. The effect of immo- bilization, in whatever way it may be eftected, is, by restraining the movements of the damaged part, to lessen bleeding, to jirevcnt the occur- rence of inflammation, to favor absorjition of cfl'usions, exudations, or extravasations, and to secure more rapid healing of the track. If there is troublesome bleeding from an intercostal vessel, recourse should be had to ligati(3n or compression, the ligature being applied directly to the artery or thrown around the rib, and compression made by ha?niostatic forceps or by tampon. Similar treatment should be ajijilicd, if jiossiljle, to a bleeding internal mammary artery ; fortunately, wound of this vessel WOUNDS OF REGIONS. 499 is very rarely observed. Hemorrhage from lesion of a large external vessel above or below the clavicle should he arrested whenever it can be done by the aj)plication of a ligature, and such operation must certainly prove less dangerous hereafter than heretofore (75 to 85 per cent, mor- tality of the subclavian and axillary ligations) ; if for any reason ligation cannot be eifeeted, compression must be employed. Hiemothorax, if the accumulation is large and the produced dyspnoea great, may be treated by aspiration, but it ('ertainly is better freely to lay ()i)en the chest, remove the clot, ami wash out tiie pleural cavity — treatment impera- tively demanded at once if tlic clot becomes infected, as indicated by the ordinary symptoms of septic infection. Empyema should always be treated by incision, with exsection of a piece of rib sufficiently large to ensure free drainage. An Estlander operation may be required under conditions similar to those making it proper in eases not consequent upon gunshot injury. Suppurative intlammations in the mediastinum necessitate prompt and tiiin'ougii opening of the abscess and careful drainage, any foreign body, ball, bone, or other, lodged in the space being removed. Should an cesopliageal M'ound be recognized, the patient must be fed througli a tube carried into tiie stomacii ; but as only two cases of such wounilized. When there is a dis- turbing amount of blood in the pericardium, jiaracentesis should be cm- ployed, or, better, free incision of the sac — an operation Avhich cannot materially increase the existing danger and may prove of great benefit. Suturing of the wound in the heart-wall has been proposed ; it is not likely to be often done.

WOUNDS OF REGIONS. 501 men. In approximately equal proportion the wonnds have been found to be of the ])arietes outside the peritoneum and intra-peritoneal, pene- trating or perforating. Hereafter the army bullet will almost certainly go through, the only foreign bodies lodging being pieces of cloth or other substances accidentally carried in. In civil practice the deep wounds are much the more comuKm, certainly so as cases present themselves in hos- pital, and their ratio to the whole number of gunshot injuries is higher; very possibly, however, their universally recognized gravity causes them to be more generally brought under such care. Of the extra-peritoneal wounds a few are contusions, l)ut in the great majdrity the missile has either entered and lodged or passed through the wall without damaging the serous membrane. Contusions have become less and less common as impi'ovements have been made in weapons and poM'der. Generally produced by spent shot, they are very apt to be complicated by visceral lacerations, which have caused death in from one-half to two-thirds of the whole number of cases. In tlie milder injuries muscle-rupture has been frequently observed, and gangrene of the damaged area with after-suppurations in the wall. When internal lesions are not present the treatment is a simple antiseptic one, with as absolute rest of the parts as can be secured ; but if because of profound shock and collapse there is good reason to believe that visceral ruptiu'e has occurred, laparotomy should be done, though the prospect of saving life is but slight. In civil life these contusions are very unlikely to be met with. When the missile has merely passed into the wall, whether it stops or goes out, the wound produced is an ordinary flesh one, the dangers of which are hemorrhage and septic infection. Foreign bodies, if they can be located, should be extracted, though there is not now the same neces- sity for finding them as in former times ; bleeding, if severe or persistent, as it often is, should be arrested by ligation of the vessel, free incisions being made if recpiired ; and a most careful antiseptic dressing should be applied. Under such treatment there is no good reason why healing should not very generally and readily take place, and the mortality-rate be decidedly reduced from the 8 per cent, or more of our late M'ar. When the injury produced l)y the shot has been an extensive one, there is much lial)ility to the after-development of ventral hernia. The Wdunds of special interest are those in which the peritoneal cav- ity has been opened. In ])crhaps 3 per cent., or even 5 per cent., of these the viscera have escaped injury,' but the probabilities in any given wound that serious damage has been done are so great that it should be assumed as a fiict that such has been the case — certainly so if the ball has ])assed from side to side, the antero-postcrior woiuuls only being those in which the organs may escape. The intestinal tract is the part most likely to be wounded, the small intestines being damaged four times as often as the large ; then follow in order of frequency the liver, the stomach, the kidney, the s|)leen, the pancreas. Of any 100 such wounds as tiiey occurred in 18(31-65, tiicre were 64 of the intestines, 17 ' Recliis and Nogiife found this condition existing in 1 out of 38 experimental shots; Senn, in 4 out of 14 ; in 30 laparotomies tabnlated bv MacCorinac simple penetrating womid was twice fonnil ; Senn observed it in 2 of his (> cases of operation (in one of which there was a piece of cloth in the cavity), and Kechis and Xogues report it as present in 17 out of 123 collected cases of shot and stab wounds. 602 GUNSHOT WOUNDS. of tlie liver, 7f each of the stomach and kidney, 3 of the spleen, and J of 1 of the pancreas. Ahiiost certainly the lesions are multiple, of the hollow viscera, of the solid, of the oiuciitiim or mesentery, of the lung, of the great vessels, etc. The number of intestinal perforations aver- ages between 4 and 5, and has been knt)\\n to reach as high as 16 or even more. The extent of damage to any viscus is very variable, an apparently explosive action being at times oljserved in the solid viscera, and even in the stomach or intestine when full of Huid. The general mortality has been very high, its rate being in our war 87.2 per cent., and in various wars, as tabulated by Otis, 75.1 per cent. Even in the less grave injuries of civil life caused by pistol balls the death-rate has until recently been generally much above oO ]ier cent. In the Chambers Street, the New York, and tiic Roosevelt hos])itals, in the vears 1876-84, of 23 cases treated conservatively 15 died — 65 per cent. (Stimson). In the five years immediately jireceding iNIay, 1887, of 32 cases in the Charity Hosj)ital of New Orleans, 19 died — 59.4 per cent. (T. G. Richardson). Of 91 cases collected by Reelus and Nogues, but 22 died — 24 per cent. As Ave shall see later, the average death-rate of cases operated upon during the last ten years has been abt)ut 66.2 per cent. This very heavy mortality has been because of shock, of liemori-Jiage, and of septic inflammation — of the latter in those cases in A\hich life is prolonged beyond a few hours. The organisms causing such inflamma- tion may be introduced from without (chiefly on the fingers of those who handle the wounded man or ujxm the instruments of the surgeon), are present in the discharges from the intestinal canal, have been carried to the damaged area in the blood-stream, or have passed through the un- wounded bowel. Shock must remain as heretofore, but under modern methods of treatment hemorrhage can be largely controlled by ligation, and the introduction of pyogenic bacteria from without be prevented, or their deleterious influence when introduced from within in some measure lessened by thorough cleansing of the soiled cavity and closure of the visceral wounds. In both hollow and solid viscera there must hereafter be less damage done by the small-calibred bullet than was formerly caused by the large, often deformed, mini& ball, at least outside the zone of explosive action. The mortality of wounds of the several \-iscera varies within rather wide limits. As observed in 1861-65, it was of the liver 63.5 per cent., of the kidneys 66.2, of the stomach 75.9, of the pancreas 80, of the intestines 89.4, and of the spleen 93.1. Of 50 cases of kidney wound studied by Edler, the mortality-rate of the 20 uncomplicated wounds of the organ was 25 per cent., and of the 30 in which there were associated wounds of importance 44 per cent. ; of 42 wounds of the spleen 83.37 per cent. died. In the pistol-shot wounds of civil life, though the present fatality of each of these visceral lesions is decidedly less, there is still a marked difference between them, the prognosis of in- juries of the stomach or of the large intestine being, as it always has been, much more favorable than of those of the small intestines. In all of the wounds of the alimentary tract, those, received A\'hen the stomach or bowel is emj)ty are less dangerous tiian those received when it is full. WOUNDS OF REOIONS. 503 The diagnosis of penetration, at times easily and definitely estab- lished, is not seldom very uncertain in default of an opening up of the track of the ball or an abdominal sectii)n. If through the external wound there is an escape of intestinal contents or of l)ile, or ])rotrusion of bowel, omentum, or j)ortion of a winuKled solid viseus, there can be no question respecting the opening of the cavity. But such positive evidences of penetration are affordetl in but a minority of cases. The presence of even small quantities of the intestinal contents in the per- itoneal cavity has been comparatively rarely noticed in pistol-shot wounds operated upon, much less often have such matters been dis- charged externally ; and the same will doubtless be true of the injuries caused by the new bullet. The ojienings are often so small that they are plugged by the pouting mucous membrane or closed by changes in the parallelism of the coats of the bowel or by the adhesion of adjacent coils of intestine oi' omentum. Sometimes the fecal extravasations have occurred only after tlie lapse of some hours or even days (because of the primary paralysis of the bowel), at a time, therefore, when this diagnostic evidence is of little practical value. Escape of bile, indicative of Hvei- wound, may be expected to take place in but about two-fifths of the cases of injury of that organ, only probably in those affecting its central part, and in but a portion of these cases will it flow out through an external wound. Hernia, whether of intestine, omentum, or of a portion of a damaged solid viseus, very rarely occurs, and is not to be ex]K'cted in M'ounds made by pistol balls or the small-calibred rifle bullet. Otis found but two instances of bowel protrusion rej)orted to the Surgeon-General during our war, a number without doubt much smaller than that of the cases actually occurring. One such case, of which no record appears in the Med. and Suiy. Histori/, came under personal observation during the siege of Port Hudson, the protruding knuckle of small intestine showing perforation wounds.' As a rule having few exceptions, the diagnosis of penetration will have to rest upon observation of the position of the wound — or, better, wounds, the ball having gone through — iqion hemorrhage from the stomach or tlie l)o\vel, blood-stained vomited material, extreme shock, collapse indicating hemorrhage in considerable amount, or, after the lapse of days, the discharge of the ball at stool. Neither shock, nor vomiting of blood or blood-stained mucus, nor bloody stools positively indicates penetration of the stomach or bowel, as either may possibly be consequent upon contusion ; liut the occurrence of these symptoms in connection with the location of the wound makes the diagnosis very ' In 1872, Asst. Surg. Patzki, U. S. A., reported to the Surgeon-General from Fort Clark, Texiis, an accitrental wound made by tlie ball of a Derringer pistol, cal. .3(5, at 1 foot distance, the shot entering li inches above the umbilicus, J inch to the right of the median line, and lodging, its location being undetermined: 2.] inches of the omentum protruded. On the seventh day after the injury this protruding omentiuu was removed with a wire ecraseur. It was at the time " firudy adherent to the sides of the wouud, thickened, more solid (carnitied), covered with grauulations secreting oticnsive pus. Patient's condition very good. Vomiting after injury, but no blood in the vomited matter or stools. The protruding ouientum, being useful as a plug, closed wound liermetically. No attempt made to return it. No symptoms of internal hemorrhage, fecal extravasa- tion, or peritonitis. Expectant treatment." Recovery rapid ; wound cicatrized eleven days later. Returned to duty twenty days after receipt of injury, bullet still remaining in the bodv. 504 GUNSHOT WOUNDS. probaljlc. A Imll ])assin^ from side to side at or below the level of the uiiibilicus, at such deptli beneath the highest point of the curve of the altdomiual wall as will more than carry it thmugh the thickness of the wall, must certainly wound the intestines. When Seun in 1888 rejjorted upon the results of the experimental rectal insufflation of hydrogen gas, it was hoped that there had been found a sure and safe method of establishing the diagnosis of bowel-wound. Hydrogen gas slowly and continuously introduced under a pressure of from l to 2 pounds was shown to pass the ilco-csecal valve and traverse the entii'e length of an uninjured alimentary canal, while if there was a wound at any point it would escape through such, distend the abdominal cavity, obliterating the liver-dulness, and find its way out through the external shot-opening, as proved Ijy its ignition when a flame was l)rought near such opening. Unfortunately, experience has shown that the test is not always reliable, the passage of the gas being at times obstructed by fecal accumulations in the lower bowel, or its escape externally being prevented by adhesions, ordinarily omental, at the inner opening of the track through the al)dominal wall. When, then, there is serious question of there being penetration, the wound should be carefully laid open until it is clearly shown that it does or does not involve the peritoneum. If the shot has passed transversely, the cut may be made in the middle line, when, if the wound is extra-peritoneal, its track will be crossed before the peritoneum is reached. It is never wise to explore the track of the ball with a finger or, much more, a probe, since penetration may thus be made in cases in which the serous membrane has not been pierced, or adhesions may be broken up or hemorrhage excited. Kidney lesion is established as a ])robability liy shock, the direction of the course of the shot, and the discharge from the bladder of bloody urine, though the latter symptom may be present in connection with ureteral contusion or laceration, or with injury of the bladder itself. When the wound is from behind, the visceral A\ound may be altogether extra-peritoneal, and urine may escape externally or into the tissues about the organ. If there is associated penetration of the j>eritoneum, there may or may not be extravasation of urine into the abdominal cavity. As shown by Redard in 1870, grave lesion of the contents of the abdominal as of the cranial and thoracic cavities is always to be inferred when there is from the beginning for four, six, or more hours a sub- normal temperature. The occurrence of j)ei'ital, the gravity of the case being much greater when in the former situation, extravasated urine finding its way into the abdominal cavity instead of into the con- nective tissue. It is to such extravasation with its resulting septic infec- tion that death is commonly due in cases not fatal from bleedingr or from associated visceral lesions. The mortality-rate of cases coming under care in military ])ractice has been about one-half (45-55 per cent.), but of those in civil life early and properly treated it is decidedly less, very much so when the bladder was empty at the time of its injury. The symptoms are — sliock, pain in the region or diffiiscd over the abdomen, and general weakness, eaeii commonly in high degree ; much irritaljility of the bladder and rectum ; luematuria ; and escape of urine tlirougli the external wound, either persistently or intermittently accord- ing to the low or high location of the opening. The last two symptoms are of great diagnostic value, though the presence of blood may be con- sequent upon contusion of the l)ladder or upon wound of some other jiart of the urinary tract, and leakage of urine may j)ossil)ly come from lesion of an ureter or the urethra, and whatever its origin it is actually met witli in Itut a limited portion of the cases of wounds caused by pistol or 510 GUNSHOT WOUNDS. small-calibre rifle balls. When there is an associated opening of the rectum fecial matter may be discharged with the urine or the urine passed through the anus. Voluntary micturition may be possible or catheterization re(|uired ; in the latter case it is advantageous for every reason to keep tiie catheter in, rather than to introduce it at stated periods or as necessary. Sometimes so much blood accumulates in the bladder that aspiration will have to be done. When there has been dis- charge of urine into the abdominal cavity, certainly in any considerable amount, symjitoms of peritonitis or of grave septicemia are ra})idly developed, the latter at times so quickly latal that upon autopsy no evidences of inflammation are to be seen. Left to itself, a case of this kind is certain to die. When urine is extravasated into the con- nective tissue in front of the bladder or into the meshes of the recto- vesical fascia, abscesses soon form or, by contiguity, peritonitis is induced. The progress of these cases of bladder-wounds illustrates the truth of Bichat's declaration that " urine is the most baleful fluid in the economy;" if not so when of normal quality, tuKpiestionalilv so when in the presence of blood and air it has become se})tic. Treatment varies as the lesion is intra- or extra-peritoneal. In the latter case a catheter may be introduced and retained and the patient treated exjiectantly. But unless, from the location of the wound or wounds antl the direction of the shot, it is very certain that the injury is outside of the peritoneum, laparotomy should be done at once, the abdom- inal cavity cleansed, and the wound in the bladder stitched ; and if there is any doubt about the nature of the injur}-, su])ra])ubic section should be made and the prevesical space, if not the abdominal cavity, opened up^ Any wound should be stitched, the parts cleaned and disinfected, and drainage secured, preferably by a gauze plug. If a foreign body, ball or bone, has lodged in the bladtler (and such loilgement has taken place in a disproportionately large number of vesical wounds), it should be removed at once if a laparotomy or a suprapubic section has been done, otherwise it may be taken away through a perineal opening either early or after the wound in the bladder has healed. Occasionally there has been an extraordinary tolerance for months or years of the foreign body. In a number of cases the ball or Ijone, or even a piece of cloth, in the Ijladder has served as a nucleus upon which the phos})hates have been deposited and stone formed. When the ball has been lodged externally, it has been known to ulcerate its way into the bladder after a time, years even, and then require removal ; and the same has been true of pieces of bone, fragments detached at the time of the injury or later separated by necro- sis. Otis reported twenty lithotomies done on account of such injuries received during our late war. Very small balls have at times been spontaneously discharged through the urethra. In the beginning of the treatment, whether operative or otherwise it matters not, fluids should be given very sparingly. Rest as absolute as possible should be maintained. Any abscess that can be located should be promptly opened. In favorable cases healing may be expected to take place in from three to six weeks. In many of the cases heretofore observed in time of war in which death did not speedily follow, recovery was very protracted and imperfect, bone-sinuses or urinary fistulae remaining ; but such sequelae are not likely to be frequently met with hereafter, WOUNDS OF REGIONS. 511 in either military or civil life, because of the changes both in missiles and in treatment, especially the latter. Genital Organs. — Injuries of these organs, rare in civil life, not very uncommon in military practice, may be either superficial or deep ; occasionally they are contusions, generally penetrating or perforating wounds, in a few instances extensive destructions. Associated injury of tiiigh or abdomen is of frequent occurrence, and to such complication death, wher. it takes place, is usually due (of 1152 wounds in our war, 144 died— 12.5 per cent.). Superficial wounds of the penis or scrotum ' are injuries of little gravity and require no special treatment, any produced hajmatocele or hernia of the testis (conditions at times observed) differing in no respect from that consequent upon ordinary traumatisms. Occasionally there has been lodgement of a ball, even of large size, under the skin, the removal of which has been easy ; in certain cases in which it has not been taken out it has become encapsulated and remained harmless for years, though its presence is likely to be troublesome. The corpora cavernosa when perforated always show considerable laceration, and the same is true of the glans penis. A'ery generally the urethra also is torn, in which case, unless proper treatment is pursued, urinary infiltration and abscess are apt to be produced. As late results of these wounds of the penis there have been seen troublesome and deforming cicatricial contractions of the organ, strictures, and fistulas, penile, scrotal, or perineal according to the location of the wound. Primary treatment has reference to the arrest of hemorrhage, the securing of jirompt closure of the wound, and the prevention or relief of urinary retention. Bleeding, which is apt to be quite free, may be controlled by the stitching of the edges of the wound together, by ligation of any divided vessel seen, or by pressure, a catheter being introduced and a bandage applied around the organ. Protecting the wound from infi'ction by the use of an ordinary antiseptic dressing will commonly secure its prompt healing. To prevent urinary disturbances (retention or infiltration) the bladder must be kept empty by a retained catheter, the edges of the urethral laceration being stitched over it if practicable, or if the loss of substance has been great the M'ound allowed to close by granulation. Much benefit will often follow perineal section and the turning of the urine through such ojiening. No matter how much the penis may have been damaged, it is ordi- narily unwise to amputate ; any part of it that can be saved should be saved. If the entire organ has been carried away, the urethra should be dissected back and a new meatus established in the perineum if the patient's general condition permits of the operation. In other than the most su))eificial wound of the scrotum the testis or cord may be expected to be injured ; in a tiiird of the cases studied by Fischer both testes were struck. The damage done the gland liy a l)ullet except at short range is rarely such as to necessitate its removal. Hernia of the testis, formerly often seen in cases of lesion by a large ball, is very unlikely to follow pistol shots or wounds by the new bullet, but atrophy of the organ has been frequently noticed, as has more or less persistent, and often intense, neuralgia. Antisepticallv treated, supi)ura- tion ought not to occur — a complication that until lately was almost 512 GUNSHOT WOUNDS. certain to lie developed. A\^hen Ixjth testicles have been disorganized they should be removed, and the wound closed by a short scrotal flap if there is enough healthy tissue left to allow of its formation. Wounds of the female genitals are rare, and they are usually in asso- ciation with grave abdominal or pelvic lesions. In the very infrequent cases in which they are inflicted at very short range the laceration that takes place is extensive. In a case personally observed in which the nuizzle of the pistol Mas thrust between tlie Ial)ia the combined effect of the bullet and the gases of explosion was to destroy almost comjjletely the vagina and the uterus. A ball passing through the unimpregnated uterus ordinarily does comparatively little harm, but where pregnancy exists there is much risk of an early fatal termination from aljortion (almost certain to take place), from hemorrhage, from shock, or from septic inflammation. In certain cases which have survived, flstula has been noticed, giving passage to the menstrual fluid for a time or perma- nently. Sword and Bayonet Wounds. Wounds of this character have been rarely seen in recent times — .37 per cent, only of the grand total of wounds in LSfJl-Oo, 1.3 per cent, in 1870-71, .9 per cent, in all the wars from the Crimean to the Franco- German, both included (437,636-4890). They must probably be much less frequent in future military operations ; the new magazine rifle, that M'ill disable if not kill at a mile, a mile and a half, or two miles' distance, p^e^■enting any considerable force of either infantry or cavalry apj)roach- ing sufticiently near to use bayonet or sabre. Surgeons hereafter will, as a rule having few exceptions, see these injuries only as they may result from individual quarrels or in mob-fighting. As made by the bayonet, and, much less often, by the straight sword, the wounds are j^imctured ; by the sabre, when sharp, incised, when with dull edge, as it generally is, lacerated and contused. The bayonet injuries are more common in the lower extremities than elsewhere (46 per cent, of the whole number reported in 1861-65), sabre wounds in the head and upper extremities (89 per cent, in the same war), though the proportionate local frequency has been quite different in different wars. Leaving out of consideration cases dying on the field, the mortality-rate is low ; with us it was 7.7 per cent, for the bayonet and 5 per cent, for the sabre wounds, the fatal cases being very largely those in which one or other of the great cavities was opened; of the 712 cases in which they were not ojiened only 16 died (2^ per cent.). Aside from visceral lesions and injuries to the large ves- sels, the chief danger of the penetrating M'ounds is in the damming up of fluids in their depths and the develojiment of su]>purative inflam- mations ; the chief danger of the contused and lacerated wounds is the occurrence of septic conditions. The appearance of the wound varies as it is made by thrust or by cut, the former being in form slit-like, triangular, or more or less cres- centie according to the shape of the weapon ; the latter sho^Wng a straight cut with more or less contusion and laceration of the edges, or the forma- tion of a flap, or an ovoid somewhat tnipped open wound from complete or nearly complete detachment of a flap, \vhich latter in injuries of the cranium may have in it a piece of the skidl of thickness according to the A BROW WOUNDS. -513 depth of" the wound. In wounds involviufj tlie kirynx, trachea, or hnig empliy.sema is often present, it may be in higli degree. The treatment is tiiat of lesions of like character otherwise produced. By thorough cleansing and proper dressing an aseptic condition may generally be secured. Vessel-wounds will necessitate the application of ligatures or not according to circumstances. Detached bone-fragments will have to be taken away. If there is puncture of the skull, trephin- ing should be done. Any foreign body, clothing, hair, or other, that may happen to have been carried in should be removed if its presence can be detected, clothing being especially likely to be lodged in the seton wounds of the soft parts. An existing emphysema, if it does not soon subside spontaneously, will necessitate puncture. Arrow Wounds. Once so common, arrow wounds are now seen extremely rarely, and hereafter their consideration will have but an historic value, since among other tlian the lowest and most isolated tril)es of savages firearms have taken the place of the bow. As met M'itli, they were of tiie nature of both punctured and incised wounds, penetrating, even perforating, the Fig. 35.

Within a range of one hundred yards or less their force of penetration might be very great, depending of course upon the strength and skill of the bowman. Often an arrow was sent through the body of an animal as large as the buffalo, bone being ])ierced as with the point of a large, strong, shttrj) knife. Striking a blood-ve.ssel, a nerve-trunk, or an intestine, such part could not glitle out of the way, but was certain to be wounded. Severe Vol. I.— 33 514 GUNSHOT \vuryi>s. hcniorrliafjo was likoly to occur. The ujiper pai't of tlic body was much uiore ot'teu injured than tlie lower, and visceral wounds were of course niucii tiie nioi'c daniicrous. ThoutJcli, as has been stated, tiie course of the arrow was straigiit, when tiie luad was of iron and tiiin it at times upon striking a bone bent itself around it. From tlie nature of tiic missile and the almost necessarily unhygienic surroundings of the patient, these wounds were in great measure infected ones; and so nuich of the mor- tality following them as was not due to loss of blood was conse(|Uent u])on se])sis. When the head iiad lodged, it was taken out whenever it was practicalile to do so, as if left it was certain to cause trouble. Such extraction, when it was separated from the shaft, was often iliHicult both in the seizing and removing. Snares and forceps of different kinds were employed to facilitate the operation, an excellent instrument which com- bined the (pialities of both snare and forceps having been iCjtariitioii may be considered as a species of fracture, since tlie injury involves a tearing away, by a sudden act of violence, of the epi])hysis from the diapiiysis of the bone, the separation occurring at the cartilaginous line of union. This injury is found only in persons under twenty-one years of age, since after that ])eriod the epi]iliyses are usually united l)y bone to the diaphyses. The rejiair is effected l)y osseous tissue, and as a result the bone ceases to develo]) at the fractured end. Shortening occurs, which may be very great if tlie patient at the time of the injury has not attained his or her full height. A complete fracture is one which entirely traverses the bone. A simple fracture is one in which the bone is broken at one point and the seat of fracture lias no comnuuiication with the external air. A compound fracture is one where the bone is liroken at one or m()re points and the seat of fracture has comnuuiication with the exter- nal air. A compound fracture must not lie mistaken for a simple frac- ture attended by a wound in the soft parts. In the former case the wound is the result of the fra( ture, and comes from within, while in the latter case the wound is ind('|)cndcnt of the fracture, and comes fnini without. A commhiiili'd fracture is one in which the bone is broken into niaiiv small fragments (Fig. .'}()). Amultijile fracture is one in which several liactui'es occur in the .same bone (Fig. 37). A complicated fracture is one which is associated with a wound ojwn- 515 516 FRACTURED ing into a joint, or is accompanied by an injury to an internal organ, to an artery, or to a nerve, or wiiich coexists with a dislocation. Fr«. 3H. CinuininutL'd fracture of tibia and filmla. An impacted fracture is one in which tiie fragment consisting of compact bone is driven into the fragment of cancellated bone (Fig. 38). Fig. 37. Multiple fracture of both bones of the leg. Fig. 38. Impacted fracture of the neck of the femur. Fractui'es may l)e subdivided again according to the direction of the line or plane of separation. An oblique fracture, which is the most common form, is one in which the line of separation is at an acute angle to the long axis of the bone (Fig. 39). A tranm-crse fracture is one in which the line of separation DEFINITIONS. 517 is at a riglit angle to tlic loiiii' axis of the bone. This variety is found chiefly in children and seldom in adults. A longitudinal fracture is one in which the line of separation is par- allel to the loner axis of the bone. This variety is rare, and is usually associated with gunshot injuries (Fig. 40). A dentatcd fracture is one of such a character that the oppos- ing surfaces denticulate with each other, so that the projections of one fragment tit into the depres- sions of the other fragment. An incomplete or partial frac- ture is one which only partially traverses the bone, as in a fracture of the external table of the skull while the internal table remains intact. Fig. 39. lli!V Fio. 40. Oblitjiie fracture of the humerus. Longitudinal fracture of femur. A greenstick fracture occurs when the bone merely bends. In this fracture a portion of the fibres are broken, while the remainder hold the bone intact (Fig. 41). This may occur as an intra-uterine fracture when the soft bones of the fcetus are bent as a result of alinormal uterine eon- tractions, or by external violence, as in consequence ]wrc(l for use alioiit the table and around the limb, in order to protect the wound from any ])ossil)le contaet with a surface not ren- dered aseptic. The wound itself should be covered by antisc|)tic jjauze, while the limb is washed with soap and water, then shaved and irrigated. Upon the limb is then poured a saturated solution of naphthalin in ether or of iodoform in ether. This application removes all the fat, and the naphthalin or iodoform remains as a layer upon the surface and protects the ]xirts. Having made aseptic all the adjacent |)arts, the wound itself requires attention. All blood and debris shoidd be washed away by a stream of warm biehloride-of-mercury solution (1 : 4000). The interior of the wound should be thorouohly irrigated with the same solution, and all hemorrhage completely arrested. Loose pieces of bone not attached to periosteum should be removed. The fragments can now be adjusted, and if the displacement is great a silver wire can be introduced to keep them in place. Again, it may be necessary to introduce, besides the wire through the bone, some deep catgut sutures, which are carried through the muscles. Deep sutures are necessary in all extensive and gaping wounds of the soft parts, especially when such uuiscles as the biceps and triceps or the (juadriceps extensor are divided. These sutures must be independent of the superticial set. All fragments of fascia, fatty tissue, muscular shreds, and lacerated integument should be cut aw'ay with scis- sors, and then a final ablution made. A drainage-tube should be intro- duced into the bottom of the wound, and if the wound is so situated as to drain well, there is no necessity for a counter-opening. Such wounds as just described require free drainage, and couriter-openiug may be neces- sary iu order to meet the requirements of the case. The tube is then cut off flush with the surface of the skin and fastened by a safety-pin. The wound is now closed by catgut sutures, which completes the opera- tive technique. The towels should now be changed and clean ones substitutetl, which should also be wrung from bichloride solution. This dressing can be done without an anicsthetic and, as a rule, with little or no pain. When the compound fracture is extensive, it is necessary to administer ether, so that the dressing can be completed from the beginning to the end while the patient is under the influence of an anaesthetic. A class of eomjiound fractui'cs is often met in which the wound is very small, and with these cases a different ]ilan should be adopted. The irrigation should l)e made around and iu the wound, and then it can be hermetically sealed by spriidiling iodoform upon a small jiiece of absorbent cotton and ]>lacing it over the perforation, and painting styptic collodion over it. This mixture will soon coagulate, the medium of sealing is surgically clean, and then the fracture is ready for the dress- ings. Thus small wounds can be hermetically scaled, medium-sized wounds closed by sutures and drained through the existing opening, and large wounds tlrained by a counter-opening and sewed with deep sutures, and the fragments held together by silver wire. Having completed the 0])erati\-e technique in one of the three ways mentioned, the parts are now prepared for the antiseptic dressings. Iodoform gauze or a small piece of oil-silk jtrotective should l)e jdaced over the wound, witii a hole cut in it to allow the mouth of the drainage- COMPOUND FBACTUBES. 525 tube to drain into the dressings. Iodoform gauze is used, because liirhloride gauze irritates tiic wound. The bichhiride gauze is next applied in loose pieces over the iodoform gauze and around the wound. This dressing is moist, because dry antiseptic dressings adjacent to a wound are sources of infection. The loose and wet gauze is held in situ, by the application of a moist bandage. Over this deep dressing absorbent cotton is placed and retained by a dry bandage. This last dressing affords a means of securing equable and uniform compression around the liml) and over the fracture. The cotton by its elasticity accommddates itself to the swelling of the parts in the vicinity of the fracture. This part of the dressing is very important as a means of preventing inflammatory swelling and of affording comfort to the patient. Four strips of sheet iron about one inch in width are now adjusted, (^ne strip is to pass down on the pos- terior part of the limb and over the heel and upon the sole of the foot. Two strips are placed upon the sides of the leg and one v\\)^n\ the front of the leg, and bent so as to conform to the shape of the dorsum of the foot. Over these strips plaster-of-Paris bandages are now applied, and the dressing is completed. These strips ])revent any backward as well as any lateral displacement of the fracture, and also do away with the necessity of a heavy splint. In three days a fenestrum is cut over the wound, and under continuous irrigation the drainage-tube is removed. The (juestion of how long this first dressing should remain is an im- portant one. Experience has taught that no splint shoidd be left on a limb longer than eight days without an inspection of the compound frac- ture. The author has seen several bad restdts arising from a neglect of this rule. In one case a fracture which was skilfully dressed with ])laster of Paris ^^'as Hrst examined at the expiration of six weeks, during \xhicli time the patient's general condition was in every way satisfactory. After removing the splint the bone was found protruding and considerable luiion had taken place. An osteotomy corrected tiic (k^formity, and in six additional weeks a perfectly satisfactory I'esult followecl. If tiiis fracture had been examined in eight days after its receipt, tiie protrusion of the bone would have been detected and the faulty jjosition rectified, ^\'hile this result is excejjtional, such unfortunate complications can ahvays be obviated by a routine inspection of the fracture. There are some questions that are of great interest when discussed in the light of recent revelations in surgical jiathologv, and which call for special study and observation in connection with the treatment of com- jjound fractures ; such aix" malignant disease, tenotomy, healing by Schede's method, amputation, the conversion of simple fractures into compound, and compound fractures involving the major joints. The question of malignant di ease following fracture is an exceedingly important one in surgical pathology. The late Dr. S. D. Gross |)ointi'd out the important fact that almost half of the cases of malignant bone disease can be traced to traumatism. The author recently operated upon a child with an inmiense sarcoma upon the occiput. The child had sustained a heavy fall upon the back of the head six months previously, followed at once by the develojiment of a large luematoma. The luematoma was not incised, and a linear 526 FRACTURES. fracture existed beneath it. For some weeks after the injury ihcre Mas nothiiifi' sj^eeial excepting the ])resenee of tlie ineniatonia, but tlie tumor then l)eg'an to grow very rapidly, and in less than six nu^Tiths from the reeeij)t of the injury the sarcoma was much larger than the child's head. The patient died some weeks after an incomplete operation for removal of the tumor. I have many beautiful specimens illustrating the fact that a fracture may be the starting-])oint of this variety of tumor. The prognosis of sarcoma affecting bone as a result of fracture, while grave, is not necessarily fatal, ])rovick'd the tumor is recognized before glandular swelling appears and the operation is performed early and includes the tissues far from the seat of disease and the bone itself. Ejiiihelioma also may develop indirectly as a result of a comj)ound fracture, but this malignant growth has its origin from the soft tissues in connection with a sinus leading down to necrosed bone. If a sinus is not healed, it becomes lined with epithelium, and a discharge of ichor- ous pus through it from time to time sets up an irritation with a pro- liferation of epithelial cells, and epithelioma may in this way secondarily develop. While the epithelioma is not directly connected with the seat of fracture, as is the case in sarcoma, ncverthek'ss, the disease inav have its origin in conditions arising from secjucstration in a com])ound frac- ture. The closure of sinuses in connection with necrosis following a fracture should always be aimed at by the surgeon. Six years ago the author called attention to tenotomy in the treatment of compound fractures, and in a luinibcr of cases since then he has been impressed with the value of the oj)eration in all obli(|uc i'om]iound frac- tures, as well as in many sim]>le fractures. Tenotomy relieves at once any^ contraction of the muscles, permits the fragments to be placed in accurate coaptation, and secures physiological rest to the fracture. It affords also great comfort to the patient, and is a valuable means of fixation during the first ten days. Tenotomy may be employed upon the tendo Achillis, u])on the hamstring nuisclcs, u])on the tendons of the arm and forearm, and even upon the sti'rno-eleido-mastoid nuiscle in fractures of the clavicle. In several cases of compound fracture of the tibia where the line of fracture was parallel with the long axis of the bone, with considerable separation, a horseshoe tourniquet has been found to be a most valuable instrument in closing the long fissure. The instru- ment by pressure overcomes the lateral separation, just as tenotomy by relaxation overcomes the oblique disjtlaccmcnt. The pad can be ap]>lied upon one side of the bone, and pressure be made by applying the other pad over a thick plaster bandage. The screw can be graduall}- tight- ened, and in a few days the bone can be ajiproximated and the instru- ment discarded. This is a safer and more satisfactory instrument than the apparatus devised by Malgaigne. IMuscnlar spasms can in most eases be overcome by position. Eelaxation of the muscles will always relieve the spasm. The use of suljihonal, as well as of many other drugs, has been suggested, but, as a rule, they do not relieve the condition. Healing h\ Schede's method is effected by the intervention of blood- clots. It has usually been taught that blood-clots in wounds are obsta- cles to repair by primary intention, and that these clots act as foreign bodies. Fluid blood and clots, if perfectly aseptic, are valuable adjuncts in the COMPOUND FRACTURES. 527 repair of oonijiound fractures. They are, however, most jiotent sources of evil if any infectiou reaches the ehit tliroui;li carelessness of the sur- g'eoii. It is a most vahiablc contriinition to the treatment of compound fractures if tiie blood whicli escapes between the ends of the fraii'ments can be in the future utilized as a means of hastening and jierfccting union by primary intention. The reason why so important a principle in snruieal patholooy has l)cen so long unknown is explained by the fact tliat blood-clots, until rigid asepsis was established, were recognized st)urces of septic infection. If all the surrounding jinrts in every compound fracture are made asc|itie, clots and fluid blood can i>e utilized for the purpose of healing. Anything short of absolute surgical clean- liness \vill convert these clots and the bhxid into dangerous agents of infection. Amjyiihttioii. — Anijnitation of the liml) in comjxtuiid fracture was formerly resorted to with great frequency in hospital ])ractiee. Before the introduction of antiseptics pyremia destroyed the life of almost every j)atient suffering from compound fracture who was brought to a large metropolitan hospital. The time is within my own recollection when, in Bellevue Hospital, amputation was immediately performed as a rou- tine treatment to prevent blood-poisoning iijion tiie admittance of a com- pound fracture ; and tliis operation was considered by surgeons as offer- ing to the patient the i)nly chance of recoxt'i-y. At the present time limbs are saved which Avould then have been sacrificed, and it is a rare event to witness an amputation in compound fracture. Extensive frac- ture of the bone with ])rotrusion of the fragments through the soft struc- tures would not now form an indication for amputation unless the soft structures were badly lacerated. Formerly the loss of a few inches of the bone called for primary am])utation, but this no longer offers an indication, for the bones are brought together by silver wire, and, though the limb may be shorter than its fellow, the member is still retained, and elevation of the shoe compensates for any slight irregularity in the length of the limb. The limits within which amputation in compound fracture may be re- sorted to are now exceedingly narrow and restricted, and this clinical fact is one of the most notable steps in the advance of modern surgery. Another im])ortant point in reference to amputation in compound fracture is the proper line of treatment to be pursued up to the time of the ope- ration. It often happens that a patient is suffering too profoundly from shock to make it expedient to amputate. In these cases great benefit is to be derived from deferring the amputation even many days, until the condition is such as to justify the operation. Formerly this could not be practised without subjecting the patient to a greater risk from septic infection than wouldbe incurred by an amjiutation during shock. If the wound is at once made aseptic and com]n-esses are jilaced over the frac- ture to control the hemorrhage, and these compresses do not extend higher than the wound itself, the amputation can be deferred. It is important that these compresses be apjilied only over the wound, and that no tourniquet or any other form of compression be a]>]ilied to the limb in the continuity of the artery above the injured part for any length of time, since if this is done there is danger of gangrene in the fla]is after the amputation. In one ease gangrene followed an ani])uta- 528 FRACTURES. tion of tlic leg where a tourniquet liad lieeii ])lacecl over the femoral artery. This j)atieiit was l)rou<;ht to tlie hospital from a ueighborino; town with a tourniquet upon the femoral artery for the ])urpose of arrest- ing hemorrhage in a compound fraeture of the leg, and I call attention to the case in order to em])hasize forciljly this point. The conversion of simple fractures into coni|)ound or complicated fractures may ha|)pen, especially when the muscular spasm is great, or (hiring the transportation of a patient suffering from a sim])le fracture.; or there may be spontaneous conversion by means of the necrosis of a small fragment. An abscess subsequently forms and pus is set free, and the seat of fracture is exposed to the atmosphere. The author has observed, for example, a Pott's fracture — that is to say, a frac- ture of the filmla three inches above the tip of the external malleolus, with a laceration of tiie deltoid ligament — converted after several weeks into a typical compound and complicated fracture, owing to the ne- crosis of the distal fragment. Suppurative arthritis of the ankle- joint ensued, with caries of the astragalus. The ankle-joint was opened, the carious fragments removed, the joint freely irrigated, and an anti- septic dressing ap])lied. The patient recovered in a few weeks with a useful joint. The possibility of nature transforming a simple fracture into a complicated one must not be overlooked. In such cases promj)t surgical interference may arrest the progress of the disease and effect perfect restoration of a joint ; otherwise this complication leads to irre- ])arable damage, if not to loss of life. The treatment of compound fractures involving major joints has been entirclv revoluti()nizcd since the introduction of aseptic surgery. The unsatisfactory results in fracture-dislocations are due in a large measure to a want of rigid asepsis on the one hand, and a too extensive operative interference on the other. For examjile, the joint may not be rendered thoroughly aseptic at the beginning, and may be too extensively inter- fered with as regards operative procedures. In the 171 compound fractures involving joints recorded in the 1000 cases referred to below the results as regai'ds the usefulness of the joint have been in nearly all the cases perfect. To have a compound fractiu-e-dislocati(jn of the ankle-, knee-, elbow-, or shoulder-joint re- paired with complete restoration of function is the aim of the surgeon. In one of the cases the asti'agalus extruded from the joint, and was rein- serted, and perfect movement of the joint followed. These ideal results are to be obtained only by the exercise of great care. In all fracture- dislocations the joint should be immediately rendered absolutely aseptic by thorough irrigation. The drainage should be entirely across the joint, otherwise a ]50cket for the retention of inflammatorv exudates is sure to form in the fold of the capsule. These products luider certain conditions are sources of great danger. A careful study of cases of fracture-dis- location reveals the history of an abscess-formation upon the side of the joint opposite to the original wound several weeks after the injury. This complication may be obviated by free drainage. It is not sufficient to drain one side only, and that side through the original opening into the joint, but the tube must pass entirely through and across the joint. Physiological rest for many weeks must then be secured, and no jiassive motion employed for at least six Meeks. Passive motion too early em- COMPOUND FRACTURES. 529 ployed has often excited inflammation which has led to suppurative arthritis. Active motion must follow in its turn, but not for some time after the employment of passive motion and massage. A proper sequence in the employment of these different agencies is most iinjJort- ant in order to reach an ideal result. The complete Iiistories of the one thousand cases of compound frac- tures have been carefully recorded. Tiie general summary is as follows : Skull 178 Nasal, malar, maxilla;, and patellae 89 Arm 40 Forearm 41 Fingers and toes 97 Ilium, clavicle 2 Thigh 87 Leg ^ . ._ 295 Fractures involving shoulder-, elbow-, or wrist-joints as a result of disease or accident 39 Fractures involving hip-, knee-, or ankle-joints as a result of disease or accident 85 Fractures involving carpal or metacarpal, tarsal or metatai-sal joints as a result of disease or accident 47 1000 Xow, following the example of surgical writers who have carefully tabulated the results of treatment in compound fractures, the author has eliminated all those cases in which primary amputations were performed, because they do not concern the jioint at issue, and, according to the practice of writers, has rejected all those cases which died of hemorrhage, collapse, shock, etc. within forty-eight hours ; in fact, most of such cases died within a few hours after injury. He has also left out cases of com- pound fractures of the hand and foot as too insignificant to be classed with compound fractures of the long bones or of the skull. In the total of 1000 consecutive (and, of course, unselected) cases of compountl fractiu'cs produced by tramnatism or by operation, there were 101 deaths, (JO ])rimary amputations, and 4 cases where the results were unknown on accoiuit of the removal of the patients from the hospital, at their own request, immediately after their admittance. In the 101 deaths, 82 died within forty-eight hours after the accident and during shock, and consequently these deaths siiould not be included in any figures to a.scer- tain the percentage of mortality, becau.se the patients died before anv plan of treatment could be adopted having reference to the repair of the frac- ture or to the prevention of septic infection. The remaining 19 deaths occurred from the following causes: One from tuberculous meningitis following some weeks after a resection of the hip-joint, so that, this case died from other causes than septic infec- tion ; another from uriemia in ••hronic Bright's disease one week after wiring the patella. The wound was, however, healed and ])erfectlv aseptic, so that this case died from other causes than septic infection. Another died one month after tre]>hining, from exhaustion and inanition, with the wound perfectly healed l)y primary intention, and, as shown by the autopsy, with no evidences in the brain of the pathological changes of sepsis, so that death in this case cannot be attributed to septic infec- tion. Two other cases died from irreparable damage to the brain, in one Vol. I.— 34 530 FRACTURES. of which the lock of a gun was driven tlinnigii tlie skull into the brain, and in the other a fracture at the base was found at the autojjsy in addi- tion to the fracture of the parietal bone, so that death in neitlier of those two cases was due to pya?mia or septicemia. Four other cases died from cerebral softening, which was situated at a distance from the original wound. One case died from dipiitiieria after the external wound of the ciimpound fracture had liealed. Tlie wound was asejitic, and was never the seat of any disturbance, and, as the diphtheria aft'ected the larynx and trachea, the cause of death was in no way connected with the fracture, altliough, of course, the time was too short to have the bone firmly united. One case of compound fracture of the skull died on the fifth day, but in this case the ])atient was suffering from a fracture of the spine which caused his death by myelitis. One case died within forty-eigiit liours after admittance from cerebral abscess connected with a punctui-ed fracture of the skull, which had been operated upon two Mceks previously by a surgeon in a neighboring town. During tlie jiatient's sojourn in the hospital he was trephined and seven ounces of pus were evacuated from the brain, but he died a few hours later. This case is excluded, on the gnnuid that the patient's injury was not treated in the hospital, and that he did not enter the hospital until within forty-eight liours of liis death. The death was clearly due to sepsis, but the circumstances were such as to relieve the hospital surgeon from all responsil^ility. One case died after forty-eight hours, but it was a case of primary ampu- tation. The patient was run over by a locomotive ; both feet were crushed, and the hanging toes were removed as soon as his condition would permit. One case similar to the last died fi-om a crushed foot ninety hours after the accident. The jiatient was over sixty years of age, and never reacted from the shock. The remaining case of death was due to lej)tomeningitis, which occurred fifty-two hours after trephining, and was due to sejisis. Finallv, in order to arrive at the mortality in this list of one thousand compound fractures, there must be deducted from the original 1000 eases 60 primary amputations, because no treatment of the fracture itself was undertaken ; 82 deaths from shock occurring within forty-eight hours, because no treatment was begun ; 4 cases where the result is unknown, because the patients left the hospital of their own accord; 155 cases of compound fractures of the fingers and toes, because tiiey are too insignificant ; also 1 8 cases just mentioned in detail. There then remain 681 cases of compound fractures witli one death due to sepals. This gives a death-rate of about one-seventh of 1 per cent. The reduction of the death-rate from 48 per cent., which half a century ago was considered a brilliant achievement and a result which was thought worthy of jniblica- tion, to that of one-seventh of 1 ycr cent, represents what surgery has done for the amelioration of human sufi'ering and the preservation of life in this special field of sui-gery. To Pasteur and to Lister the profession are indebted for this great work — the former as the discoverer of the means, and the latter as the one who ap|)lied the discovery to surgery. Complications. — Compliccdions during and after repair of fractures forms a most interesting subject for observation and study. The com- plete usefulness of a limb is not fully restored as soon as the fracture has been repaired. During the process of repair, as well as after union COMPLICATIONS. 531 is complete, it is jjossible for many comjilications to arise that rccjuire special treatineut. Surgical emphysema is a condition that is often met with in the man- agement of fractnres. This consists of the entrance of atmosplicrie air into the meslies of the connective tissne, and is termed "surgical emphy- sema " to distinguish it from emphysema of the lung. The source of tiic intiltratiiin of the air into tlie connective tissue may be from injury of the lung in fracture of the rib, in wiiich case the emphysema has been observed to reach to the scrotum, and at times it may spread over the face, so that the jiatient is unrecognizable. The air may escape to such an extent as seriously to embarrass respiration. Another source of emphy- sema may be from the generation of gases as a result of putrefactive changes or of the growtii of gas-producing bacilli in the tissues. There are only a few cases oljserved of emphysema in simple fractures ; the majority of the cases have been comjilications in compound fractures. Or the gas may escape from a wound in tlic intestine, or even from the air-sinuses in the bones of the face and skull. If the emphysema arises from injury to the lung, no interference is indicated unless the emphysema is so extensive as to produce dyspnoja, in which case free incisions can be made or the air allowed to escape through a trocar. The air is usuall}^ absorbed in a few weeks, and produces no harm, since it has been filtered in its jiassage through the lungs, and is therefore incapable of setting up inflammation. In case tile condition arises from putrefactive changes, the apjilication of the ]>rinciples of antiseptic surgery is required ; if from a wounded intestine, a laparotomy must be performed at once, the peritoneal cavity rendered aseptic, and the wound closed. Q^demn consists of the infiltration of serous fluid into the interstices of the areolar tissue, and, unless it is due to some organic disease of the liver, kidney, or heart, is the result of too tight bandaging or the sudden removal of tiie splint, or, finally, of obliteration of the large veins frijui thrombosis. If due to local causes, the oedema usually disappears after the removal of the cause, or, if to a loss of support of the vessels by the removal of the splint, the oedema rapidly subsides as soon as the function of the limb is restored. Placing the limb under a faucet and doucliing it alternately with hot and cold water will stimulate the circu- lation ; and this treatment, aided by the action of the muscles when the patient begins to walk, will relieve the condition. Delirium tremens and traumatic delirium are two complications that frequently occur. The differential diagnosis is often difficult to make, but tremor in the limbs and an alcoholic history, with absence of fever, point to the former as contrasted with the latter condition. In both forms of delirium the ]iatient has delusions, mutters incoherently, is often violent and excitable, and has a dry, tremulous tongue accompanied by free diaphoresis. The treatment consists in placing the fracture at once in a plaster-of- Paris splint and watching the jiatient carefully, even to the extent of employing a special attendant. If the delirium becomes too active, and it is impossible to restrain the jiatient, a strait-jacket must be cmplo}'ehining the bone above it if necessary in order to reach the disease, with a view to destroying the micro-organisms with a solution of bichlor- ide of mercury. The application of the ]n-inci])lcs of antiseptic surgery will destroy the disease, and if not amputation of the limb is indicated. Fdf-cmbolism was first fully described by A\'agner and Zenker. Fat-embolism means the entrance of fluid flit from the medulla of the bone into the veins in the immediate vicinity of the fracture, and through these channels into the capillaries of the brain, spinal cord, lungs, kidneys, and other essential organs. The presence of fluid fit in COMPLICATIONS. 533 the blood was descril)ed in 1836 by Dr. R. W. Smitli, but the clinical importance of this condition was not I'ecognized until recently through the investigations i)f Bergniann, Czerny, and Scriba. Dejerine has ex- perimentally produced fat-embolism in the lower animals by inserting laminaria tents into the medullary cavity of the l)one. The symjitoms of fat-embolism appear on from tiie third to the fifth day as a rule, and resemble those of secondary shock. They occur before the time at which venous thrombosis or pulmonary embolism would be expected to appear. Great dyspntea, associated \vith tlie Cheyne-Stokes respiration, irregularity of the heart's action, with a sudden rise of temperature, together with twitching of the nuiscles, as well as paralysis of certain muscles, have been observed in these cases, and also fat-globules are found in the urine. There have been no metastatic abscesses discovered where an autopsy has been made. This group of symptoms must not be mis- taken for shock following fracture nor for jiulmonarv enil)olism. Shock may be said to be present three hours: after the fracture, fat^ embolism ihrer dai/s after, and jiuliiKinary embolism three veeks after. For convenience these complications have been arranged in the order in which they are most likely to occur, and by associating these condi- tions, which simulate each other, with the time at Avhich they appear, no mistake in diagnosis is likely to arise. The treatment of fat-embolism consists in the administration of etiier in the form of some such preparation as Hoffman's anodyne, or even l)y hyjiodermic injection. In ease of great dyspnoea venesection has been suggested, and also artificial respiration. The pulmonary oedema must be relieved by cardiac stimulants and by cupping. The fracture should be kept perfectly quiet, lest any movement of the fragments might cause furtlier absorption of the fat by disintegrating the medulla. In cases wliere there is great cimiminution of bone and disintegration of the medulla amputation may be immediately indicated as a life-saving expedient. lished. The author some yt'ars ago published a report of one thousand com- pound fractures, and in this list there was no case in which finally union was not obtained. Assuming that one eomjiound fracture occurs to every ten simple fractures, there woidd be nearly ten thousand cases of fractured bones in which the author cannot recall a single case of per- manent non-union. AMiere the fragments could be approximated they in a few cases failed to unite after several attemjrts in the way of o])erative in- terference, but finally a union was effected, although in several cases as many as seven or eight operations were performed. The femur and the hiimerus occasionally fail to unite, and, next to these, the bones of the leg, and lastly the bones of the forearm. That part of the bone which is away from the direction of the nutrient artery is most likely to give rise to non-union. In the sitting posture, if the elbow- and knee-joints are strongly flexed, the nutrient arteries take a direction downward, or in the upper extremity the nutrient arteries run loirard the central joint, wliile in the lower extremities the nutrient artries run cncaji from the central joint. From this anatomical law the upper part of the humerus would be the most frequent seat of ununited fracture ; and in siqiport of this statement out of 13 cases reported of ununited fractures of the humerus, 9 were in the upper extremity of the bone. In 8 ununited fractures of the forearm, 7 were in the lower part. In the same manner, ajiplying this anatomical law to the lower extremity, it is found that the cases of non- union are found in a very large proportion of the cases in the lower jiart of the femur and in the upper part of the tibia. The intra-capsular frac- ture of the neck of the thigh-bone is an exception, but in this case the non-union is due to special causes, which will be considered in a dis- cussion of this special fracture. The (xtuscs of non-union in bones after fracture are constitutional and local. Among the constitutioval causes, in which the reparative action is impaired or misdirected, may be mentioned old age and certain con- stitutional diseases, as fevers, syphilis, scurvy, malignant disease of bone, and rickets. Paralysis may also be a cause, as is illustrated by a case NON-UNION OF BONE. 537 of spinal injury with fracture of the linnierus and leii of the same side, in whieli the arm united, hut the k'g failed to unite. The puerperal state is another eonstitutional cause whicii has been mentioned hv some writers, but the author has never found this condition to permanently cause a non-union in fractured bones, although in some cases the bones fail to unite until after parturition or until several opera- tions have been performed. Among the local causes of non-union may be mentioned the direc- tion of the line of fracture, since oblique fractures are more frecpiently attended Ijy failure of tuiion tJian transverse or impacted. Among the other causes may be found sei)a)-auon of the fragments, the interpositiou Fig. 44. of foreign botlies between the ends of the broken bones, or suppuration, profuse hemorrhage, the continued use of wet dressings, and, finally, improper dressings, in which the splints are either too tight or too loose The treatment ot non-iuiion of bone following fracture is to be con- sidered from a constitutional as well as a kical jioint of view. It is the union of the two methods that is sure speedily to bring about the desired object. In every case a careful incpiiry should be made in regard to certain diatheses. The treatment of this unfortunate condition has for its oliject the correction of any constitutional dyscrasia. A syphilitic diathesis should be treated with the full administration of antisyphilitic remedies ; a gouty or rheumatic tendency, by remedies suited to these special diseases ; scurvy, rickets, scrofula, tuberculosis, and marasmus should be treated with tonics and a nutritious diet, with the aid of the best hygienic surroundings. The tonics best suited for those condition.' in which the general health is impaired are iron and the phosi)hates. In conjunction with the general management the local treatment is to be pursued. The means emjiloycd must consist of the removal of any offending body between the fragments and the excitation of a certain amount of inflammation aroiuid the ends of the fragments. The local treatment must further consist in the application of an immovable splint specially ada])ted to the exigencies of the case. The operations which have been devised with a view to effecting union in ununited fra<"ture are nniltifarious. They all have one common olijcet — viz. the excitation of inflanimation ; but many of the old operations are at the present time abandoned as a result of the introduction of anti- septic surgery. The use of the seton, the injection of irritating fluids, the cauterization of the fragments, the application of blisters and of caustic alkalies to the skin over the site of the ununited fracture, the s 538 FRACTURES. Fig. 45. introduction of electrical cnrrents, the violent jiercus.sion witii the mallet, — are among the varions operations which are practically discarded as luisnitalile, and in their place.s modern surgery has instituted a number of asej)tic operations. Before any other operation is attempted it is good surgery to try and perforate the bones, which is best accomplished by a Bi-ainard drill. This operation is simi)le, is attended with no special danger, and in the majority of cases will bring al)out firm union. This method is espe- cially indicated in cases where the patient's healtli is impaired, or the patient is aged, or where any lesion of important organs exists, such as would render a more serious operation a source of great danger. This operation can be accomplished without the administration of ether, and with but little pain, by the use of the freezing atomizer and by the hyjHidermic injection of cocaine through the ana\sthctized skin : a small incision is made, and the drill is thrust into the Ijone. The drill pene- trates the fragments in twenty or thirty places from the same opening in the skin. In these cases the ends of the fragments are usually devoid of periosteum, and the intervening tissue forming a false joint is jiartially insensitive ; hence the pain is not unbearable. The soft parts around the seat of fracture shoidd be thoroughly cleansed before drilling the bones, and the small puncture in the skin made aseptic before being hermet- ically closed. Closure of the wound is best eft'ected by iodoform powder freely sprinkled over the wound, and over the powder should be painted styptic collodion with a thin film of borated cotton, and in this way a firm scab is formed, which closes the wound and converts the small comjiound frac- ture thus made into a sim])le one. The drilling causes considerable in- flammation, and the determination of 1)1(1(1(1 to the part carries with it the materials for osseous repair. This simple operation is worthy a trial in ununited fractures, even though sub- sequently a more serious operation under ether might become necessary. The operations fiir non-union in fractures where drilling has failed consist of cutting down upon the site of the fracture and exposing the false joint. Great care should be exercised to avoid wounding any of the import- ant vessels and nerves. The inter- vening fibrous tissue should now be cut away, the two ends of the bone brought out, and a small piece of each end sawed otf, so as to .secure a fresh osseous surface. The manner of further procedure must necessarily depend upon whether there are two parallel bones or there is only one single bone in the extremity. If there are two bones, no union can be effected unless a corresponding section of w \V I COMPLICA TIONS. 539 the opposite bone is removed, in order to have tlie broken ends brought in apposition (Fig. 45). Tliere are several methods of fixation of the exposed fragments. In some cases the ends can be sutured by silver wire, and little shortening Fig. 46. 'J u Volkmaun's operation for pseudarthrosis. is likely to follow. . In other cases this method is inapplicable, since the ends are often too pointed to afford a sufficient breadth of surface Fig. 47. n. H. Smith's splint for ununited fracture of the thi^^h. for union. Under these circumstances the jieriosteum should be pre- served as far as possible, and a resection be made in each fragment, as Fig. 48. H. H. Smith's splint for ununited fracture of the les. shown in Fig. 46. The fragments can be fastened together by ivory pegs or by steel nails, or even sutured by strong silver wire. Palliative measures are sometimes indicated where an operation for 540 FRACTURES. any reason seems inadvisable. The aceompanying cuts illustrate the principle upon whicli sucli treatment is based (Figs. 47 and 48). In extreme cases, where tlie limb is useless, and suppuration is present to such an extent as to endanger life, am})utation may be called for. Such treatment may be indicated where an operation to effect union has failed and su])iiuration and necrosis have followed. It occasionally happens that no operation for pseudarthrosis is per- missible, in ^\hieli case a splint should be used, so that the patient can have a greater sense of security. Special Fractures. Fracture of the phalanges occurs as a i-esult of direct violence, such as the passage of a wagon-wheel over the toes or by the fall of a heavy N\eight directly upon the ])art. Fractures of the toes may also be caused by the patient striking the foot against a chair or sofa while walking barefooted in the dark. If the fracture is compound, the wound can be dressed aseptically and a small splint applied, and the entire foot envelojied in a plaster-of- Paris bandage. The soft j>arts are very vascular, and tlie repair is very ra])id and satis- factory. The danger from tetanus in ccmijiound fractures of the toes must not be overlooked. In the sim])le fracture* of the phalanges a pasteboard splint should be a])plicd ^\•et and moulded to the toe, and the foot placed in a plaster-of- Paris bandage. Fractures of the metatarsal bones occur in much the same way as those of the phalanges, only the degree of injury inflicted is greater. The same general rules will suffice in the management of fracture of these bones. Fracture of the tarsal bones occurs from direct violence, and is usually associated with great destruction of the soft tissues. The skin is very apt to slough, and much care must be exercised in order to pre- serve the integrity of the tissues. Fractures of the scaphoid, cuneiform, and cuboid bones do not require any special consideration beyond that exercised in the general management of fractures of the metatarsal bones of the phalanges. Fracture of the calcaneum usually is the result of a fall from a great height M-here the patient strikes upon the heel. This fracture has occurred a number of times in workmen on elevated railroads. The men in endeavoring to avoid a passing train have lield themselves sus- pended in tiie air from the iron structure, and, not having strength enough to hold on until the train had passed, have dropped to the ground, and, striking ujion the hard pavement, have broken the calcaneum of each foot. The fracture may also be produced by a wheel of a carriage or cart passing over the foot laterally while the patient is lying on his side upon the ground (Fig. 49). Fractures of the calcaneum may occur from muscular action, as \\here the tendo Achillis is suddenly contracted and tears the insertion of the muscle from its attachment. The detached tendon often carries with it a thin shell of bone from the posterior part of the OS calcis. The signs and symptoms of fracture of the calcaneum are such as to render the diagnosis clear. Crepitus, pain, swelling, and ecchymosis SPECIAL FRACTURES. 541 are present. The heel itself is often contnsed, and is discolored from the bruise caused by falling upon the integument over the heel. The arch of the foot is often destroyed. The disjilacemcnt varies in degree according to the situation of the fracture ; thus, if the break traverses Fig. 49. Fracture of os calcis. tlie part of the calcaneum in front of tiie attachments of the lateral ligament, there is usually but slight deformity, since the strong ealcaneo- astragaloid ligaments holds the fragments in situ. On the other hand, if the fracture is behind the insertion of the lateral ligaments, the tendo Achillis dra\vs the posterior fragment well up, so as to cause a marked and characteristic displacement. The dcn.se fibrous tissue surrounding the Ijone also helps to prevent much displacement. The treatment of .fracture of the calcaneum varies somewhat accord- ing to the seat of fracture. If the bone is broken in front of the inter- nal lateral ligaments, the den.se fibrous tissue about the bone and the sole of the foot prevents any marked dis])lacement. The foot should be placed in the .^lightly extended position and a plaster-of-Paris bandage at once applied. If the bone, on the other hand, is I)roken behind the insertion of the lateral ligament, the disi)lacement is well marked, and it becomes necessary to place the leg upon a double-inclined plane in order to relax the tendo Achillis, which causes the displacement. In 542 FRACTURES. the treatment of tliis fracture division of the tendo Achillis will at onee cause the deformity to disa])pear and the frat that tiie bad results after this fracture are due to incomplete drainage, to imperfect antisepsis, to improper splints, to the adoption of too early passive motion, and, finally, to the employment of active motion before the ])roper time has arrived. The question of incision into the joint in a case of simple fracture of the astragalus, with a view to removing the fragment, is one about which no unanimity of opinion exists. Some surgeons prefer to wait and let Nature make the expulsion of the fragment, and not to interfere until suppuration ensues, while others believe that with the aid of anti- septic surgery a bold operation should be essayed. No general law can be laid down, and each case must be treated on its individual merits. Fractures of the leg may be classified into four groups: Frac- tures of the tibia and hlnda, of the tibia, of the filnda, and epiphyseal separations. Fractures of the leg form about 1(3 per cent, of all fractures. They are rare in inf incy and during childhood, but between the ages of thirty and sixty the greatest number t)f fractures of the leg are found. Fractures of the leg are usually the result of direct, although they may be caused by indirect, violence, or even l\y muscular action. As a rule, the direction of the fracture in the lower part is oblique, while in the upper extremity of the limb the fractures are transverse. At the outset too much stress cannot be placed upon the importance of so lifting the broken leg as to ensure absolute certainty against the conversion of a simple into a compound fracture. The patient should first be instructed to relax the muscles of his broken leg, and on no account, no matter how severe the pain is, to contract his muscles so as to resist the assistarit whose duty it is to raise the limb. Ha^'ing fully explained the importance of this to the patient, the assistant should grasp the foot at the juncture of the phalanges with the metatarsal bones, and make gradual extension in the long axis of the limb before attempting to raise it. As soon as the fracture is reduced he should lift the leg slowly from the bed. In this manner no accident can follow, and the pain consequent upon this necessary manipulation is very slight. Fractures of the tibia, and fibula occur by direct violence in the great majority of cases. They may, however, result from indirect violence or even by muscular action. They are produced by heavy weights falling upon the limb, by the kick of a horse, or by the passage of a car- wheel or heavy truck over the leg. When both of the bones of the leg are broken by indirect violence, the tibia is fractured lower than the fibula. This is probably due to tlie fact that the tibia is broken first, and the fibula then gives way upon a higher level. The signs and symptoms of fracture of the tibia and fibula need no special description, since they are most marked in this special fracture. The irregularity of the line of the tibia is often a most important diagnostic sign. The displacement in fracture of both bones of the leg needs special consideration. The lower fragment, with the foot, is drawn upward and backward behind the upper fragment by the action of the 544 FRACTURES. Fig. 50. Fracture-box, with movable sides. (ing.

Thei'e are likewise abduction of tlie foot and rotation of the leg out- ward, caused by the weight of the foot and of the lower fragment, owing to the loss of support. The treatment oi'a simjile fracture of Ixith bones of the leg eonsi.sts in the application of a suitable retentive a])]iaratus. If there is much tension and swelling on account of inflammatory exudation, with hemorrhage and blebs or phlyctena', the limb should be -placed in a fracture-box ( Fig. .50), so that it is surrounded by oakum or bran. In a few days the swelling subsides, provided the limb has been kept quiet in the fracture- box. The phlyctenre will disappear after they have been simply punctured with an aseptic needle and a small piece of iodo- form gauze placed over the collapsed vesicle. If, on the other hand, there is no marked swelling, and no blebs upon which the pressure of a splint would cause .sloughing exist, the limb can be immediately placed in a permanent dre bone is placed reasons. The early dressing of a fracture often jtrevents the swelling so frequently found where there has been delay in the a])plication of a ])er- manent and early splint or bandage. As to the selection of a special dressing for fractures of both bones of the leg, the opinions of surgeons are at variance. The writer has no hesitancy in recommending, with the exception nientioned, the inuiicdiate use of plaster of I'aris in fractures of both Ixines of the leg. The great objection raised to immediate appli- cation of the plasti'r-of-Paris bandage is the danger of gangrene from pressure due to swelling. The writer has seen this unfortunate accident occur on several occasions in the hands of well-known surgeons ; but it is certain that the gangrene was not due to the use of the plaster-of-Paris bandage per .sc, but to the improjier and careless use of it. The writer has also seen a case of fracture of both bones of the leg in which plaster of Paris was immediately applied, and the entire limit became one ma.ss of sloughing material concealed under the bandage, Avhile the septietemia resulting from this condition gave rise to the incorrect diagnosis of typhoid fever, from which sujjposed cause the patient died, but the incidental removal of the ]>laster bandage at the dead-house revealed the true cause of the septica'mia. The manner of applying a plaster-of-Paris liandage (Fig. •'Jl ) is fully described elsewhere, but the special points in connection with the manage- ment of this particular fracture are first the use of a thick layer of absorbent cotton which will yield to any .swelling, and thus prevent the danger of gangrene ; and, second, the use of strips of jterfoi'ated tin or zinc placed over the limb to give uniform support, and thus to obviate the necessity for a heavy bandage. These strips should be fitted to the sound limb, and then placed laterally in front, and along the posterior part of the broken leg, and bent around the heel .so as to prevent any backward displacement of the limb during the repair. Great imjiort- ance is to be attached to this posterior splint. As a matter of precaution SPECIAL FRACTURES. 545 the toes should be examined after six hours to see if they are numb or if there are any signs of obstructed circuhition, in whicii case tlie splint should be immediately cut off and a new one applied. At the expira- tion of eight days, if everything lias proceeded favorably, a new splint should be applied. In another week the bandage should be removed to Fig. 51. Leg encased in plaster-of-Paris bandage. inspect the fracture, since occasionally the fragments become disturbed under the l)andage, and at this time they can be readjusted when later it would be impo.ssible. If the surgeon prefers a .splint instead of the pla.ster-of- Paris bandage, the classical double-inclined plane of Mclntyre is one in common use. Where there is much deformity and the fracture is not easily retained in apposition, this splint is useful, since it relaxes the mn.scles of the calf by flexion of the knee. In some cases of oblicpie fracture this splint is not well ada])ted to meet the emergencies of the case, as it does not over- come the tendency to rotation, and also because in flexion of the knee the quadriceps extensor muscle of the thigh has a tendency by its contraction til tilt forward the lower end of the upper fragment. Hahsted's sliding splint is most excellent when there is any tendency for the upper fragment to jjrotrude. The writer has employed in certain cases the ordinary fracture-bo.x with the addition of a weight and pulley to the lower fragment. After the leg has been placed in the fracture- box, which is filled with bran or oakum, with the movable sides turned down, a pad is placed under tlie tendo Achillis, and the sides are now closed up, leaving the vertical foot-piece flat. In cases where there are great .swelling and a tendency fir the njipcr fragment to protrude through the skin this dressing is fiund most useful. Nathan R. Smith's iuiterior sj)lint (Fig. 52) is recommended in frac- tures of both bones of the leg, as well as in fractures of tlie thigh. The Bavarian splint is excellent if the fragments can be kept in appo- sition without artificial extension or muscular relaxation. In this same category may be mentidued the silicate-(if-soda bandage, the lateral splints of leather or gntta-])ercha, and tlie heavy pasteboard side-splints. In the use of any of these side-splints care must be exercised to avoid the tendency of the backward displacement of the lowei- fragment with the foot. Vol. I.— 3j o4G FRACTURES.

Smith's anterior splint. line with the inner edge of the patella, and the foot maintained at a right angle to the long axis of the limb. In fractures of the n})per part of the leg the knee-joint may be in- volved, and then hwmarthrosis results, \vhich may lead to serious joint disease. If the fracture is compoimd or complicated, the knee must be thoroughly irrigated and drainage-tubes inserted into the sides of the joint, since the open wound is often unsuitable to utilize for ])urposes of drainage. This is a serious operation, and nnist be performed in con- formity to the rules laid down in connection with compound dislocations of the knee-joint. Fracture of the tibia is of more frequent occurrence than frac- ture of the fibula, because the lione is less protected by muscles and receives the principal weight in falling. The fracture may occur at any point in the shaft, but the junction of the middle with the lower third is the more frc(pient seat, since this jwrtion is anatomically the weakest part, owing to the fact that the diameter of tlie bone is less at this place than at any other part of the shaft. In this jtart the jieculiar anatom- ical arrangement of the bony columns is such as to favor fracture upon the receipt of indirect violence. The bone is fractured at this place often by torsion. Fractures of tlie tibia occurring in the lower part of the bone are usually obli(jue from ai)oye, downward and inward, while those in the upper part are transverse. The fractures in the lower part may be from direct, but usually they are from indirect, yiolenec, while those in the upper part are generally produced by direct- violence. Fractures of the tibia may occur at the lower end, through the shaft, or at the upper end. A fracture occurring at the lower end of the tibia usually involves the SPECIAL FRACTURES. 547 Fracture of the internal mal- leulus. internal malleolus. There is very little displacement, because the inter- nal lateral or deltoid ligament, which is attached as well to the borders as at the apex of the malleolus, prevents the fragment from becoming detached. This injury often results in a perma- nent ankylosis of the ankle-joint (Fig. 53). The signs and symptoms are so apparent that they need no special tlescription. The treatment consists in placing the detached fragment in its proper position and retaining it by the use of com- presses placed between the malleolus and the inner side of the splint. It is highly important to ha\c the fragment accurately adjusted, since any union in an abnormal position will result in too great lateral motion to the astragalus, and thus render the patient unable to walk with any sense of security. If the fragment cannot lie placed and retained in its proper position by the ordinary measures, the operation of cutting down upon the fragment and wiring it, or of fixing it by the use of an ivory peg, would be in the hands of an antiseptic surgeon a just procedure. If the union is fibrous, it is a})t to interfere with the free movement of the ankle-joint. Fractures of the shaft of the tibia are not attended with much dis- placement, since the fibula acts as a side splint to keep the parts in apposition. In some cases the only signs that are present are fixed pain, localized tenderness on pressure, ecchymosis, a tendency to back- ward displacement, a slight irregidarity upon jKissing the finger down the tibia, as well as an irregularity upon the surface of the bone. If the fracture hapjiens to be in the lower third of the tibia, crepitus may be felt by gras])ing the foot firmly and rotating it. The treatment consists in the application of side-splints of leather, pasteboarfl, or gutta-percha, or in the use of a plaster-of-Paris bandage applied in the manner already descrilied. Fracture of the upper end of the tiljia is usually transverse and the result of direct violence in consequence of which the soft parts are more or less bruised and contused. There is usually but little displacement, since the transverse direction of the fracture prevents any marked deformity ; if, however, the fracture is oblique, then the displacement is prominent. In this fracture by direct violence, where the bone is liroken transversely, occasionally a T-fi'acture is found, and the line of fracture extends verti- cally into the kn.cc-joint. In tliis case a eonsiilerable degree of deformity is jiresent, since the knee-joint becomes at once the seat of acute synovitis, produced by the presence of blood within the capsule and also by the direct effects of the trainnatism. ' If the fracture is oblique, the leg is defleetcd to one side, o)i])osite to the direction of the line of fracture. Tile treatment of this injury, situated in the up]ier part of the tibia, consists not onlv in the iiianagemcnt of the fracture itself, but also in attention to the joint complication. It must embrace, therefore, a plan to reduce the infianimatory joint affection, as well as a retentive ajiparatus for the fracture. If the displacement is considerable, the deformity can be best overcome by the use of Mclutyre's (Fig. 54) double-inclined ])lane, which 1)V relaxing the hauistring luuscles prevents any move- 548 FRACTURES. ment in tlie long lower fragment, and makes this fragment conform to the upper or short fragment. The action of the quadriceps extensor is to tilt the upjier fragment forward in case too great flexion of the knee is allowed. If but slight deformity exists, the fracture can be com- pletely reduced and a plaster-of-Paris bandage employed, with a com- FiG. 54.

In some cases, where the muscles of the calf make traction on the lower fi-agment, tenotomy of the tendo Achillis will often overcome any tendency of the upper margin of the lower fragment to override the lower margin of the upper fragment. After three weeks gentle passive motion should be employed in order to prevent adhesions in the knee-joint. At the beginning of the treatment it may be neces.«ary to use cold evaporating lotions, the ice-bag, or Leiter's coil to reduce the local Fig. 55. Mclntyre's splint ami Salter's swing. inflammatory condition of the joint. In all fractures of the leg in ^xhich the j>laster-of-Paris bandage is employed it will be found that a suspension apparatus, such as Salter's swing (Fig. 55), will enable the patient to keep the fragments more quiet than when the leg rests entirely upon the mattress. SPECIAL FRACTURES. 549 Fig. 57. Fig. 58. Epiphyseal separations (Fig. 56) occur in young people under twenty years of age, and since they are produced in the same way as fractures, and present the same sym])t()ms, and finally demand the same treatment, there is little to say in connection with them beyond what has already been said in relation to simple fractures of the bone in these localities. If the epiphysis is separated in a child, the growth of tlie bone is very nuich aflbcted, so that when the patient has attained his full size the injured leg is much shorter tiian the opposite one. This shortening must be relieved by the use of a cork sole applied to the shoe. The treatment should be the same as for a Separati..ii ..i lUe i.jw.r n . i> ii 1 • -ii i. ii epiphysis of the femur fracture ot the lione occnrruig either at the upper (Bryant). or the lower part of the siiaft. Fracture of the pibuea may occur at any point, but there is only one special fracture that tleserves separate consideration. This is known as " Pott's fracture," and consists of a fracture of the fibula about three inches above tiie external malleolus, with a laceration of the internal lateral or deltoid ligament, and in some cases a slight chip- ping off of the tip of tiie internal malleolus at or near the insertion of tlie ligament. This fracture is pi'oduced by a fall ujion the foot, and the foot is twisted (Figs. 57, 58) outward, and occasionally there is a sligiit dislocation of the ankle-joint, caused by the astragalus rotating upon the under surface of the tibia. In some cases, besides the lesions just mentioned, the foot may be dis- located backward, since the lateral supports have been destroyed. Displacemcut m Potfs fracture. Tlie treatment ot fracture of tlie nbula, with the exception of Pott's fracture, is extremely simple, since the tibia itself acts as a splint, and any ordinary dressing, such as leather, pasteboard, gutta-percha, or side-splints, will answer every purpose. In Pott's fracture there are only two dressings which are woi'thy of special consideration : the first being a plaster-of- Paris bandage, a|)plied while the foot is held in marked inversion, witii the addition of a strong poste- rior splint of perforated ziiie, which is moulded first to the sound leg and then applied to the broken limb, in order to prevent the backward dis- j)lacement, a deformity .so apt to follow during the rejiair of this frac- ture. The otiier dressing is that known as Dupuytren's (Fig. 59), which consists of a board about four inches in width and of sufficient lengtli to extend from the popliteal space to three inches l)elow the foot. On the fractured leg a pad is placed which reaches from the popliteal s]>ace to the internal malleolus, with a thickness of one inch at the upper end and three inciies at the lower end, where it extends to the tip of the internal malleolus. The leg, with the pad applied, is now laid laterally upon the splint, wliicli is maintained by means of a few turns of a 550 FRACTURES. roller bandage above and lielow. The application of the lower bandage eauses adduction of the foot, which relaxes the internal lateral ligament and brings the fragments in correct ajiposition. The limb is placed upon the side with the splint in contact with the bed. Fig IKipuytreirs ;sj"lint. Fractitre of the patella demands careful consideration on account of its close proximity to tiie knee-joint, and also in consequence of the imperfect way in which the fragments usually unite. Fracture of this bone occurs in about 2 per cent, of all fractures, and it is found more frequently in the male than in the female — in the proportion of about 5 to 1. The period of most frequent occurrence is between the ages of thii'ty and fiity. If the fracture occurs in extreme okl age, it is very likely to be found in the female. Fracture of the patella is caused by muscular action or by direct violence. The direction of the fracture may be transverse, vertical, oblique, or even stellate. In the fracture produced by sudden and violent muscular contraction the transverse variety usually oeem's. When the fracture is caused by direct violence the direction may be vertical, oblique, or stellate, or the fracture may be eonniiinuted. The fracture by muscular action occurs when the knee is in the position of semi-tlexion. When the joint is in this position the middle portion of the nnder surface touches the anterior surflice of the condyle. A sudden and forcible con- traction of the quadriceps extensor muscle, which acts at nearly a right angle to the vertical surtiiee of the patella, causes it to snap, just as a stick is broken across the front of the knee. A fracture caused by nniscular action is complete, and has also associated with it a tearing of the aponeurotic and fibrous coverings of the bone, as well as a laceration of the synovial membrane of the joint and a rupture of the prepatellar bursa. In consequence of the peculiar nature of this injury the joint is soon filled with blood, and the synovial secretion becomes abundant as a result of the irritating pressure of the blood-clots. In fracture of the patella the knee-joint is always opened, unless the extreme lower end of the patella is broken, in which case it is possible for the fracture to exist without the joint involvement. Both patellae may be fractured by muscular action. The writer has seen this in a case of an insane patient who suddenly attenqited to sj)ring out of a window. This accident has also been re])orted as the result of sudden extension of both limbs during the performanct' of lithotomy without an anaes- thetic. The fracture of both patellae has also been observed in a patient who attempted to save himself from falling backward on account of a misstep. Fracture of the patella caused by direct violence is the result of sudden force applied directly to the bone, such as a kick from a horse, SPECIAL FRACTURES. 551 Fig. do. a blow upon the anterior .surface of the bone, or a fall directly upon the front of the knee-joint. In this fracture there is more injury to the soft parts about the joint, alth<>u<;h usually the .separation of the fray- nients is not so great, on account of the al)senc'e of muscular contraction. This fracture produced by direct yio- lence is often compound, and also, in some cases, connuinuted (Fig. (JO). The signs of fracture of the paiella vary sonie\yhat according to the man- ner in which the injury occurred. The history of a fall during which the patient felt a sudden snap, or of a blow upon the knee-joint with some instrument, or of a kick by an animal, together with sudden loss of p(jwer in the limb, lengthening of the patella Avith a well-marked sulcus, with ec- ,, , , , , . n . . - . -' Cumpountl frat'lure of i)atL'lla. chymosis and swelling rapidly appear- ing, with a loss of the general contour of the joint, — are characteristic indications of fracture of the patella. The amount of separation between the fragments depends upon the (k\gree of muscular contraction at the time of the accident, together with the amount of synovial secretion and the extent to whicli the lateral attachments of the patella are lacerated, and, to a certain extent, u))on the contraction of the liga- mentum ])atell8e. A patient has been known to walk after fracture of the patella, but this is a most unusual eyeut. C're])itus is generally absent in this fracture, on account of the separation of, and the inter- vention of blood-clots and fibrous tissue between, the fragments. A certain amount of displacement is sometimes found after the fracture has been re])aired ; for example, the fragments may be displaced to the side or in front. The lateral displacement is caused by the ligamentous or fibrous union stretching unequally, while the anterior dis])lacement is due to the pressure of pads placed above and below the fragments, which causes them to tilt forward. The fragments may be i)uslied up by the underlying fluid, so that their anterior surfaces are not on the same plane. The usual mode of union, to which, of course, there are exceptions, is not osseous, unless the fracture has been treated by opening the joint and suturing the fragments with silver wire. The question as to whether bony union eyer takes jilace In- the older method of treatment is settled without any doubt. A s])ecimcn in support of this statement is fouiil(lom unites by bone is that at the tune of the accident the fibrous tissue or the 552 FRACTURES. capsule of the anterior .surface of the patella falls down between the frag- ments, and thus acts as a foreign body and prevents the coaptation of the bony surfaces, and consequently union by bone is rendered imjiossible. The treatment of fi-acture of the patella consists in the aj)plicatioD Fic. 61. Fiu. 62. Osseous union after a fract\ire of patella.

Some special mnnagenient of the joint-infiammation before applying any permanent dressing is necessary. There have been pnblishe • ^ i- rrlane and to su])port and steady the foot. The distal end of the inclined plane may be elevated from six to twelve inches according to the length of the limb and to other cir- cumstances. Upon either side, about four inches below the knee, is cut a deep notch. The foot- piece stands at right angles with the inclined plane, and not at right angles with the horizontal floor. Having covered the ap])aratus with a thick and soft cushion carefully ada])ted to all the irregularities of the thigh and leg, especial care being taken to fill completely the space under the knee, the whole limb is now laid upon it, and the foot gently Levis's modification in place.

The body of the patient should also be flexed upon the thigh, so as the more cflectiially to relax the (juadricejis femoris muscle. A roller is now apjjlied to the knee by obliipic and circular turns, commencing above the ]>atella, and traversing the notch in the .sjilint, each successive turn covering more of the front f)f the knee until the whole is enclosed. With a second roller the entire liml) must then be secured to the splint, this roller extending from the ankle to the groin " (Fig. 66).

A roller is now applied above and below, which secures the thigh and leg to the splint (Fig. (58). As the swelling subsides all that is necessary to maintain the adjustment is to tighten the strips by screwing up the pegs to which they are fastened. By this plan the removal of the dressing is ren- dered unnecessary until the cure is complete. Between the third and fourth weeks the strijjs may be separated from the jiins, the knee gently moved so as to overcome stiffening, and the dressing again adjusted. This process should be repeated every five or six days until the fifth week, \\-hen the splint may be laid aside and the patient be placed on crutches." ' Wiring the patella is an operation which within a few years lias been brought prominently into notice, especially through the labors of Dr. Charles Phelps. The operation is one about which much honest diver- sity of opinion exists. The arguments in favor of the operation are the absence of great danger to life and limb, the superior results as regards the function of the joint, and the greater rapidity of repair. In refer- ence to the danger to life, it may be stated that Dr. Phelps reported (in 1890) 111) cases of wiring the patella in New York City, in wliich there was no death directly attributed to the operation, and but one death due to delirium tremens — a complication tliat would have occurred in any other operation. In the hands of a thorough aseptic surgeon the danger to life from sepsis is insignificant. The superior results as regards the function of the limb are demonstrated by the invariable presence of bony union and a freely movable joint. The rapidity and completeness of repair is made evident when it is considered that ]iatients have walked well within three weeks after the ojieration, have walked a mile within six weeks, and later on have played football. On the other hand, some surgeons claim that the operation is too seri- ous, and that results which are sufficiently satisfactory can be obtained by less severe measures. Tlie author feels justified in recommending the operation in cases where there is no organic disease, when every pos- sible antiseptic precaution can be secured, and M-here the 2)ersassive motion will soon restore the joint to its jJerfect function. The conclusions, after a careful analysis and study of all the reported and as many unrej)orted cases, are these : In compound fractures of the ])atella there is not the slightest question as to the ])ropriety of the operation of wiring the fragments. In recent and old fractures, with the facts fully presented to the patient and under the strictest antise]itic precautions, the operation, in the light of present statistics, is wholly justifiable. In debilitated patients and in those suffering from any organic disease the operation siiould not be employed, and is, in fact, contraindicated, as are all other o])erations of expedieu(y. It is not an operation whieli can l)e indiscriminately performed, and never by an ordinary practitioner with little surgical experience and with little faith in the germ-theory of inflammation. The success of this operation depends wholly upon conscientiously carrying out the smallest details needed to secure aseptieity, and the surgeon ^vho is not imbued \\\i\\ the true spirit of antiseptic surgery ought not to ])erform this operation. While the number of cases yet operated upon is too limited to admit of deductions by means of which a final settlement of this question can he made in the minds of surgeons, the future practice of the surgery of this and of other countries will soon enable us to condemn it as an unsafe and unjustifiable procedure, or else it will be conceded as one of the grandest triumphs of our art. Compound fracture of the patella is a most serious accident. Thei'e is but one method universally recommended, and that is, under the influ- ence of an anaesthetic, to enlarge the original wound, irrigate thoroughly the joint, drain it with rubber tubing, and wire the fragments with silver wire. If the operation is performed with aseittic precautions, tiie tubes can be removed upon the third day and the wound closed, and an ideal result secured. This injury in pre-antiseptic days was usually attended by a fatal result, but with the application of the principles of modern surgery the cases, as a rule, do well, and the final result is perfect as regards the restoration of the function of the joint. Fractures of the Femur form about 6 jier cent, of all fractures. In the aged they occur usually in the upjier third, in ciiililrcn in the middle third, while in adults the fractures are generally found in the lower third of the bone. Fractures of the shaft, however, may occur at all ages, but fractures of the neck of the thigh-bone are usually found in the aged, and esj)ecially in women. SPECIAL FRACTURES. 559 Fractures of the temur in the upper third may be classified according to the seat of the fracture ; thus, intra-capsular and extra-capsular frac- ture of tlie cervix femoris ; trochanteric fracture and subtrochanteric fracture of the shaft ; in the middle third according to the variety of the fracture : thus, simple, compound, comminuted, gunshot, and complicated fracture ; in the lower third according to the part fractured ; thus, exter- nal, internal, and supracondyloid fracture and ej)iphyseal separation. Epiphyseal separation is an injury which is classified with fractures for reasons already mentioned. This injury occurs before the twentieth year of life, at which time the lower epiphysis unites to the shaft, and any injury of the lower part of the bone occurring as the result of accident or during an attemj)t to lircak up ankylosis of the knee in a patient under twenty with tiie symptoms of fracture suggests a separation of the epiphysis from the diaphysis. In the discussion of supracondyloid fracture the treatment of epiphyseal separation will be considered. Supracondyloid fracture occurs about two inches above the epiphyseal line, and is usually the result of direct violence, as a blow upon the side of the fenuir or a l)low upon the patella while the knee is flexed. The fracture is situated at the point where the cancellated bone tissue joins the compact bone tissue. The signs and symptoms are the same as in any fracture, with the additional sign of loss of contour of the knee-joint. The femoral artery may be wounded in this fracture, caus- Fjg. Oy. ing a false aneurism, %vhicli is of serious import. The displacement consists of flex- ion of the lower fragment on its trans- verse axis by the action of the (Fig. 69) gastrocnemius, plantaris, and pop- liteus muscles, while the rectus and hamstring muscles tend to i)ull the Fracture of ilic lower part of tlK* femur.

This disj)laceinent can be over- come in one of two ways : either by division of the tendo Achillis or by the use of tiie double incline plane.

It occasionally happens that the joint becomes involved by the fracture Fig. 72. ^Jt II -M 1 Natlian R. Smitli's anterior splint. assuming a T-shape (Fig. 70) and thus extending into the joint through the intercondyloid notch. The treatment of supracondyloid fracture, as well as of epiphyseal separation, is conducted upon one of two principles : either by relaxing by natural means the hamstring muscles by the use of a double-inclined SPECIAL FRACTURES. 5C1 ])lano, or by artificial means, by division of tlie tendo Achillis, which secures physiological rest to the limb by causing a temporary jiarah'sis of the muscles, and thus preventing them from contracting and drawing down the lower fragment. Extension should never be employed in the straight jiosition, since tliis has a tendency to iutcnsifv (Fig. 71) the dis- placeuKnit and cause permanent ankylosis in the knee-joint. The leg and thigh can be placed in a wire cuirass, which is bent to represent a doul)le-inclined plane, or Nathan Smith's anterior splint (Fig. 72) can be used, or jtlaster of Paris can be a[)plied witli tlie knee-joint sliglitlv Hexed. In case tiie fracture is compound, the wound must be made thorougiily aseptic, and free drainage of the knee-joint, with complete immobiliza- tion, must be employed. Internal comlt/loid fracture (Fig. 73) is produced by direct violence through a fall upon the bent knee, or by a blow upon the condyle, or by a severe lateral wrench. Tlie accident may be serious on account of the proximity of the knee- joint to the fracture. The signs and symptoms are the same as are found in ordinary fractures, such as localized pain, ecchymosis, crej^itus, and mobility of fragments. The length of tlie limb is not altered, but the nor- mal contour of the j'»int is destroyed. The treatment consists in jtlaciug the entire limb in the straight position and applying some evaporating lotion over the knee-joint for a few days, so as to raodif}' the inflauimatory reaction. The fragment must then be adjusted in its proper ])lace aud held in tiitii by compresses. Flexion of tlie knee has a tendency to displace the fragment upward. Ankylosis is apt to follow unless the joint is subjected to gentle passive motion at the end of three weeks. The important clinical fact must not be overlooked that the fragment may foil to unite, and sup- puration of the knee-joint has liecn observed in a few cases. Such a complication calls for the practice of bold antiseptic surgery. Aspira- tion of the joint in this fracture is unwise, since it might lead to serious joint-complication. External condyloid fracture is caused by a blow or a fall upon the condyle when the knee is flexed, and, like fracture of the internal con- dyle, may be serious on account of its close proximity to tlic knee- joi'^it- The signs and symptoms are the same as in internal condyloid fracture, and tlie treatment mentioned for one is applicable to the other. Fractures of the tthaff of the femur usually occur about the centre of the bone. Tliey are generally oblique, with the line of fracture in the antero-posterior direction. Tliey are (caused liy direct or indirect violence or by muscular action. Direct violence causes fractures in the lower third ; direct and indirect violence, as well as muscular action, may cause fractures in the middle third ; while fractures in the u})per third of the bone are generally the result of indirect violence.

The author has seen death result in conseipience of shock incident to simple fracture, but, on the other hand, has treated several cases of double compound fracture of both thighs in which but little shock was present and the patients made excellent recoveries. If the fracture is complicated with an injury to the femoral vessels or a laceration of the main nerve-trunk, the progno- sis is most serious, since gangrene may occur. The treatment of Iracture of the shait of the femur is somewhat complex, on account of the many different varieties of fracture which present themselves, as well as owing to the multifarious methods still in vogue. The indications are to overcome shortening, to control muscular pain and spasm, and to produce fixation of the fragments. Fi(i. 76. Adliesive plaster applied for extension. It seems wholly umiecessary to review the older methods of treat- ment, since the recent ones are generally accepted as far superior in every respect. The first indication VIZ. to overcome shortening — is Fig. 77. E.xtension apparatus fur Iracture of the tliigh (modifierl from Gurilcn B\uki. met l)y the u.se of the weight and pulley (Fig. 77), known as Buck's extension method. The amount of weight required (k'pends upon the age of the individual, the amount of mu.scular rigidity to be overcome, and the 564 FRACTURES. Fig, direction of the fracture. In applying tiie adhesive plaster to the limb the strip slioukl extend above the knee-jidnt and nearly iij) to the seat of fracture, since this gives less freedom of motion and takes the strain off from the knee-joint. The amount of weight required to overcome the shortening varies from five to twenty- five pounds. The less weight that is used, the more likely it is that the ])atient will tolerate the extension for a long time (Fig. 77). The counter-extension is made by elevation of the loot of the bed. Another method of maintaining extension to overcome short- ening is by the use of a spica of plaster-of- Paris band- age applied while the muscles are relaxed during anaesthesia. This extension is maintained by the use of strips of perforated zinc or tin under tlie jilaster, and a])plied according to Fluhrer's method. Still other methods are by the vertical extension of the thigh (Fig. 78); or by Liston's long sj)lint with its perineal band, consisting of a tubular bag filled with wool or a soft jmkI made of leather ; or by Owen Thomat^'s hip-s]ilint ; or l)y the stirrup of Brown or Cripps ; or, finally, by Nathan K. Smith's anterior sjilint. The next indication — viz. to control muscular spasm and pain — is best met by the use of a long sj^lint to which the thigh can be bandaged, and the entire limb thus kc])t in its proper relation to the trunk. If the nniscvilar si)asm and irritability are severe and cause mucli pain, tenotomy of the hamstring muscles will at once relieve this condition. Tiie last indication is met l)y the use of coa])tation splints, four in number, placed around the thigh over the seat of fracture. They should be two inches wide and about eight inches long, well padded and fixed to the limb by strips of adhesive or rubber plaster about one inch in width. In case of fracture of the thigh in children, employ either the spica of Fracture of the femur in a child treated by vertical extension. ' Fig. 79.

In contusion of the hijHJdiut the presence of tlie head of the bone in the acetabulum and the al)sence of all the characteristic signs belonging to fracture serve to render the diagnosis clear. A fracture within the capsule can be diagnosticated if the head of the bone is in the acetabulum and immediate shortening has occurred, for under these circumstances, unless the fragments are impacted, crepitus, eversion of the foot, shortening of the limb, and loss of function are always present, and make the diagnosis certain and the s]>ecial line of treatment perfectly clear. The surgeon should make a judicious choice as to the special method by which a patient with this injury is to be treated. If the patient is in good phys- ical condition, not too aged, and not of a nervous temperament, an attempt shduhl be made to secure union in the fracture. To this end a long Liston splint should be adjusted, and a weight and pulley attached to the foot in order to steady the leg and overcome a certain amount of shortening. During the period of repair attention must l)e directed to the avoidance of bed-sores and to the maintenance of the general health, upon which so much depends in the management of these cases. All parts of the hndy must be kept strictly and absolutely clean, and the patient sujtported by the most nutritious diet, with judicious stinndation if necessary. Anodynes may be indicated in case of loss of sleep or to contnd pain, while remedies to aid digestion and tonics containing the hypophosphites of lime and soda can be emjdoyed M'ith advantage. In some cases this fracture can lie treated by a plaster-of-Paris spica, wliich is a form of dressing which does not confine the patient to the bed, but permits him or her to rest on a lounge or even to be moved around in a roller chair. Great care nuist be exercised lest the splint produce excoriation of the skin in elderly people, since this will lead to the formation of bed-sores, a most unfortunate, painful, and often fatal complication. In ntlier cases patients arc intolerant of the use of any 570 FRACTURES. splint or dressing, and seem nidre (Mimfortabie witlioiit any fixed appa- ratus, except ])erliaps sand-hags, wliieii serve to prevent rotation of the linil). A liglit weigiit applied to the foot will sometimes help to keep the fracture quiet and atlbrd the patient relief. It has been suggested to unite the broken surfaces by ivory pegs, but this operation is one of a serious nature and of doubtful expediency in tiie ag<>d. Tile best result that can l)e attained is often very unsatisfactory, and in many cases the ])atieuts succumb from the effects of this injury. \i tile fracture is imjiacted and the patient is in good physical condition, occasionally an excellent result follows. Fractures of the pelvis form considerably less than 1 per cent, of the fractures, and derive their chief importance from accomjianying injury to the pelvic viscera. In this resj)ect fractures of tiie ])clvis resemble fractures of the skull, in which tiie gravity is influenced not so mucli l)y tlie extent of the fracture as liy the damage sustained by the contents of the skull. Fractures of the pelvis (Fig. 84) may be situated along the crest of Fiii. 84. Fracture of the pelvis. the ilium, in the pelvic basin, or in the acetabulum. Fractures involv- ing the crest of the ilium are usually produced Iw direct violence, as by the pa.ssage of a wagou-wheel across the pelvis, or Ijy a heavy weight falling upon the patient, or by crushing while in the act of coupling cars. The signs of this fracture are pain, crepitus, ecchymosis, and ina- bility to move the muscles attached to the ilium. SPECIAL FRACTURES. 571 The treatment consists in keeping tlie patient quiet in bed and the application of a long Liston splint reaching from the axilla to the ft)ot. The fragments themselves can be adjusted and held in .sitii by the aj)plication of pads or compresses, which are retained by adhesive plaster, or liy a Bavarian plaster-of-Paris splint applied so as to tit all the salient points of the pelvis, or by a gutta-pereha or felt splint applied after first moulding it to the sound side. Frnrfure offhrpdvicbaniii is usually situated in the jiubic bone. The direction of the fracture is through tlie ujiper ranuis upon the inner side of tlie jM'ctineal eminence, and tlien through the lower ramus near the point at wliich tlie pubis joins the iscliium. The displacement is very slight, as a rule. Palpation of the outline of the pelvis will often reveal the amount of displacement. The prognosis in this fracture is dependent upon the existence of visceral injury. In the absence of any injury to the viscera suppuration in the loose connective tissue in front of the bladder is a complication that often ensues. The signs and ssrmptoms of fracture of the pelvic basin consist of localized pain, greatly increased upon pressure, inability to elevate the limb, crepitus, ecchyniosis, and displacement. In these cases there is usually injury to the pelvic viscera. The urethra may be lacerated as it passes under tlie arch of the }>ubis, either by a sharp fragment of bone or by separation of the symphysis. A catheter, thoroughly cleansed and boiled, should be introduced into the urethra down to the seat of the laceration, and then an external perineal urethrotomy performed. It may not be necessary to o]ien into the bladder, but a sound must be passed ut stated intervals in the future to avoid the formation of traumatic •strictures. A catheter should be immediately introduced into the bladder for the purpose of ascertaining whether a rupture of this viscus has oc- curred. If clear urine escapes, it is presumptive evidence that the blad- der is uninjured. This, however, is not an absolute proof, and further investigation should be made. Eight ounces of Thiersch's antiseptic fluid should be injected into the bladder, and if this exact amount is immediately witlidrawn ruptui-e of the bladder is in all probability not present. Even this procedure is not an infallilile test, since a rent in tlie bladder-wall has been found of a valve-like character, so that disten- tion of the bladder closes the opening and no fluid escapes into the peri- toneal cavity, although a rupture of the bladder-wall exists. If after a few hours folhjwing this examination Inematuria occurs, some doubt may arise as to tlie accuracy of the diagnosis. The question then to decide is whether the blood found in tlie urine has its origin from the bladder, or wlicthcr the liiood is from tlie kidney as a result of laceration of tliis organ. The presence.of hiematuria occurring some hours after a pelvic fracture, the fact that the blood is uniformly mixed with the urine, and not found in clots, as is usual in hemoi'rhage from the bladder, and the evidence derived from the microscopical examination of the bloody urine, will make aljsolutely certain the diagnosis as to the source of the hemor- rhage and the injury of the viscera. Hsematuria, due to an injury to the bladder-wall or to the kidney- substance, must not be mistaken for a hemorrhage from the urethra dependent upon a laceration of this canal at the triangular ligament. 572 FRACTURES. The passage of a sound will ciiMbk' the surgeon to arrive at a conclusion as to this possible source oi" Jieniorrhagc. A digital examination of the rectum should be made to ascertain if the pelvic vessels are torn or if the bowel itself has sustained any injury. If the patient is a female, it may be necessary to make a vaginal examination in order to be sure that none of tlie pelvic organs are injured by tiie fracture. If the exam- ination reveals the fact that the bladder is injured, a lajjarotomv should be immediately performed, as tirst descril)ed in detail l)v Sir Wm. Mac- Cormac, the peritoneal cavity should be irrigated, the wound in the blad- der-wall closed, and drainage during repair maintained, either by a tube brought out at the lower angle of the abdominal \\onnd or else by a soft catheter introduced into the urethra and kept ase])tically clean. The management of the fractur(> itself is conducted uj)on the same principle as that of fracture of the ilium. The long Liston splint should be applied to both limbs, slight flexion of the knees with modi'rate extension by the double weight and jiulley should be employed, and the adaptation of some form of pliable splint or bandage, such as felt, leather, or plaster of Paris, should be made in order to kec]) the fragments at rest. Fractures of the acetabulum may occur sinuiltaneously witii a disloca- tion of the hip, but this special variety of fracture is exceedingly rare. The frac- ture, when independent of a dislocation, may involve only the rim of the acetab- ulum, most fre(piently the posterior lip, or it may involve the floor of the acetab- ular cavity. It sometimes haj)pcns that the head of the femur is driven through the floor of the joint-socket into the pel- vic cavity (Fig. 85). The signs and symptoms of fracture of the acetabulum consist of pain, ren- dered acute by pressure over the trochan- ter major ; an acute synovitis of the hip- joint, with all the manifestations of effu- sion within the capsule ; the presence of crepitus in some cases ; or the evidences of impaction of the head of the bone in Comminuted fracture of the acetabulum. Other cases. If the head of the bone has been forcibly driven through the floor of the joint-cavity into the pelvic cavity, there are also present the signs of injury of the pelvic viscera. The complications are to be treated according to the rules just laid down in discussing this question in connection with fractures of the pelvic basin. The fracture itself can be best treated by the same method as intra-capsular fracture of the neck of the thigh-bone or a fracture of the pelvic basin. Fracture of the iiyoid boxe seldom occurs, owing to the mobility of the bone and the protection which is aftorded to it by the inferior maxil- lary bone. These fractures are usually caused by a direct blow upon the neck or by some one throttling the patient in an attempt at violent assault, or by a fall from a height, or during the act of judicial or SPECIAL FRACTURES. 573 suicidal lianging. The junction of the body of the bone with the greater cornu is the usual seat of the fracture. There are some cases recorded where a fracture of this bone has occurred as a result of mus- cular action. The signs and ssnnptoms are those wliich are found in common witli ordinary fractures of other bones. The patient usually hears a sudden sna[), and at the same time experiences, with a sense of sutfoca- tion, acute pain. There is usually a slight hemorrhage from the mouth, produced by a laceration of the mucous membrane of the pharynx. Movement of the head is attended witli severe pain, and tlie j)atient is unal)le to ])rotrude the tongue. The voice is hoarse, and articulation as well as deglutition becomes very painful. Dyspncea, expectoration of bloody mucus, and irregularity of the pulse are symptoms often observed. The prognosis is favorable if the fracture of the bone is not asso- ciated with injury to the larynx, but when this complication is present nearly 50 per cent, of the eases are fatal. The danger of axlema glottidis must not be lost sight of, since this condition is likely at any time to arise. Treatment. — An attempt should be made at once to reduce the frag- ments l)v placing the left index finger of the surgeon in the patient's moutli, and witli the thumb and index finger of the right liand making external jiressure until the fragments arc brought into apposition. If tiic parts art' not easily bi-ouglit together, it may he necessary to administer an auiestiietic, during wliich the surgeon must guard against the danger of the patient swallowing the tongue. The patient's head should now be flexed forward, and lield in this position by some retentive apjiaratus which extends from liotli sides of the head to the slioulders. A collar consisting of leather or felt or jilaster of Paris, like the Bavarian splint, can he jtlaccd around the neclv and ap])licd to it wliile wet, so that the collar can adapt itself to the salient points of the neck. The oesophageal tube must be used to feed the patient, who for ten days at least must not be allowed to talk. (Edema f//ofii(lin (Fig. 8ti) is a coni]ilication that may arise at any moment, and if iiiflani- niation or dyspncea is present a prophylactic tracheotomy should be immediately performed. If the soft parts within the mouth are lacerated and there is much ecchymosis externally, it is best to perform a prophylactic tracheotoiiiy, as it is unsafe to upper and lower rilis in tiie interspace. Tlie pressure can now be made directly upon tlie l)leeding vessel. This tampon can be subsequently removed by diminishing its size by removing some of the narrow strips of gauze with wliich the glove-finger has been packed. The emphysema is not to be interfered with, since the air will event- ually become ab.sorbed, and, altiiough the patient may be unrecognizable on account of the general swelling, tlie condition itself gives no cause for alarm. It occasionally hapjiens tliat the air is so freely distrilmted that wiien it reaches the 'loose cellular tissue of the neck respiration is seriously embarrassed, and in this ease a few incisions through the integument will suffice to allow the air to escape. It is, however, only under extraordinary circumstances that incisions should be made, since this apparently simple procedure has been followed by death. If the emphysema invades the mediastinnm or forces its way into the inter- lobular tissue of the lung, tliis condition is not amenable to surgical treatment and forms a most serious complication. In fracture of the ribs in which there is little or no collapse, and the 576 FRACTURES. patient is a strong, pletiioric individual and suffering from dyspnoea and impending asphyxia, venesection is indicated, and will remove at once tlie alarming distress and discomfort, since by this means the venous congestion and pulmonary engorgement are innnediately relieved. The coHtal cdiiildt/c^ may be fractured, either at their junction with the rib or even in the middle of the cartilage itself. The fracture of the cartilage is jirodueed by the same causes as fracture of the ribs, and the signs and symptoms and treatment are similar. FitACTURE OF THE STERNUM occurs in less than 1 per cent, of all fractures. This is owing to the elasticity atibrded to it by its connec- tions with the ribs, and also to its sjiongy structure. It may be caused by direct violence, as a heavy blow upon the chest, or by a heavy weight falling upon the patient, or by a gunshot wound. This injury has also been observed as the result of indirect violence, as in bending the body suddenly liackward or forward, and occasionally a fracture has been observed after a fall Tijion the shoulder, in which case the force is transmitted along the clavicle and ribs. Several cases of fracture of this bone have been reported as a result of muscular action during labor-pains. A case has also been reported where the patient fractured the sternum by endeavoring to lift a weight with the teeth while the body was placed in the position of ojjisthotonos. The fracture is usually simple and transverse, and it is generally situated at the junction of the manubrium with the l)ody of the bone (Fig. 87). If the fracture is due to a gunshot wound, it may of course be situated at any part of the bone. It sometimes happens that the lower extremity of the bone or the ensiform cartilage is the ]iart broken. The displacement is usually slight, on account of the periosteum in fi'ont and behind the bone. The lower fragment is usually displaced forward and (iverla))s the lower margin of the ui>per fraoment. -'» Tiie signs and symptoms of fracture of the sternum are — fixed jiain, which is increased by a deep inspiration or expiration ; cough, attended by expectoration of blood and marked irregularity of the action of the heart, with dys}>nwa ; flexion forward of the head and trmik ; change in the outline of the bone ; and crepitus, felt by placing the jwhn of the hand over the sternum while the ])atient coughs. In some cases, how- ever, crepitus can be detecteil only by means of the stethoscope. The prognosis in this fracture is favorable, unless it is complicated with a fracture of the sjiinal colunui or the ribs or the clavicle, or by a hemorrhage into the anterior mediastinum. The treatment consist in the application of a liroad band of adhesive plaster placed around the chest in the manner already described in the dressing of a fractured rib. It may be necessary to a]>j)ly a compress to the fragment which is tilted forward, and this dressing will maintain the apposition of the fragments. In reducing the fracture the jjatient should be placed in the position of opisthotonos, with a hard jiillow under the back. In this attitude of the body the advancing fragment can be brought into coaptation with the receding fragment. The suggestion of Petit, of cutting dt)wn upon the bone and elevating the fragment, or that of Nelaton, of passing a hook under the fragment, is not to be recommended. The dangers of injury to the pleui'a and pericardium, of suppuration in the anterior mediastinum, and of conversion of a simple into a compound frac- SPECIAL FRACTURES. 577 ture, are too great risks to run to relieve a deformity which ordinarily pro- duces no disturbance.

FR.vcTrRp:s of the clavicle occur in about lo per cent, of all fractures. They are common, because the bone is prominently ex]50sed, and receives all shocks transmitted to it by falls ujion the shoulder, elbo\\', and hand. This injury also occurs from direct violence, as a blow upon Vol. L— 37 5/8 FRACTURES. the shoulder or by a heavy weifi;ht falliiij;- u]W)ii it, and has been known to result from nuisciilar aetioii, on aeeount of the strong contraction of the deltoid and the clavicular ])ortion of the pectoralis major, an example of which is reported in an atteni])t to lift a carriage-top while seated in the carriage. Fractures of the clavicle are rare in elderly pe(i])le, and exceedingly comnicm in rhildrcii, in wliom half of tlie cases occur before the fiftli year. The seat of the fracture may be in the body of the bone or at the acromial or sternal extremity. The most frequent .seat of fracture of the clavicle is in the body of the bone just external to the centre, since at this place the bone is least in diameter, and at the same time it is the junction of the outer and sudilcn curve with the inner curve. This is the case upon exposure to indirect violence, while following direct vio- lence any portion of the bone may be broken ; but the sternal end is less frecpiently broken, since the direct force of a blow upon the shoulder is usually attended by fracture of the acromial end, which receives the full force of the injury. The fracture is generally simj)lc, altiiough the writer has seen two cases of compound fracture, excluding gunsiiot fractures. The double curve in the body of the clavicle prevents it from breaking as often as if it were perfectly straight, since the curves transmit the force over a greater space. It is a noteworthy fact that it seldom happens that Fig. S8. Displacement of inner and outer fragments in fraeture of clavicle. fracture of the clavicle is associated with other injuries, such as fracture of the adjacent ril)s, injury of tlie pleura, laceration of the important axillary vessels, or stretching of the cords of the brachial plexus. Any or all of these complications may occur, but, considering the frequency of fracture of the clavicle, it is extremely rare to find any of these concomitant injuries. The displacement in fractures of the clavicle consists of an elevation SPECIAL FRACTUBES. 579 and projection of the sternal end of the hone by the aetion of the clavic- ular portion of the sterno-eleido-mastoid muscle (Fig. 88), and a depres- sion of the acromial extremity by the weight of the arm and by the action of the pcctoralis minor muscle, and also by the lower fibres of the pectoral is major and the deltoid acting from its humeral insertion. The outer frag- ment is also rotated by tlie action of the scrratus magnus muscle, which has a tendency to draw backward the inner extremity of the outer frag- ment ; which fact explains the frequency with which the fragment per- forates the loose skin over the clavicle, and thus causes a compound fracture. The signs and symptoms of fracture of the clavicle vary some- what according to the special seat of the fracture. Besides the ordinary signs indicative of fracture, there are some special signs and symptoms which are characteristic, among which may be mentioned the interrup- tion in the line of the bone; the loss of power in the muscles attached to it ; the flattening and depression of the shoulder, which falls downward by the weight (if the arm, inward by the action of the pectoralis minor and the subelavius, and to some extent of the pectoralis major nuiscle, and forward, on account of the shape of the thorax ; and, finally, the turning of the head and neck toward the injured side in order to relax the muscles, which cause pain by their contraction. Among other signs may be mentioned the nearer approach of the affected shoulder to the mesial line of the sternum, the close proximity of the arm to the side of the chest, and the loss of th.e support of the elbow, which is generally held up by the patient's other hand. The treatment of fracture of the clavicle, on account of its extreme frequency, has commanded the attention of surgeons in every country. The different kinds of apparatus and appliances all aim to bring the shoulder upward, outward, and backward in order to overcome the dis- placement, which is downward, inward, and forward. Tf a jxitient will consent to lie on his back in bed for two weeks upon a firm and hard mat- tress, with a small pillow under the head, and the affected arm held close to the side of the chest by a long, heavy sand-bag, this supine position will accomplish more satisfactory results than any dressing yet devised. The recumbent position upon the back causes the shoulder to assume its normal relation. A sand-bag placed over the point of the shoulder will assist l)V depressing it, and tlicrcby bringing the fragments into apposition. The results obtainctl by this simple method are far superior to those obtained by any other, since the fragments unite without any overlap- ping and the callus is not so exuberant ; and in the case of a lady, in whom the recjuirements of dress compel her to expose her neck, the dis- figurement of a callus is sometimes more dreaded than the forced con- finement in bed for t\\'o weeks. It is only occasionally that a woman's vanity will induce her to choose this mctiiod of treatment. li' the patient will not consent to remain in bed, the best and simplest method is that of Sayre, who describes his dressing in the following manner: " After drawing the arm backward and retaining it tiiere by a sti-i]i of adhesive ])laster, pass another piece of plaster from the well shoulder across the l)ack, and by pressing the elbow well forward and inward the first ])Iaster around the middle of the arm is made to act as a fulcrum, and the simuldcr is necessarily carried upward, outward, and 580 FRACTURES. backward ; and the plaster, being' cari-icd o\'er the elbow and forearm (wliieli i.s flexed across the chest) to the opposite siioulder, the place of starting, and then secured by pins or stitches, permanently retains the parts in position Strong and good adhesive ])laster is cut into two strips three to four inches wide (narrower for children), one piece long enough to surround tlie arm and go (•(ini]>letely annuid tlie body, the otlier to reach from the sound shoulder around the elbow of the fractured side and back to the place of starting. The first piece is passed around the arm just below the axillary margin, and pinned or stitched in the form of a loop suffi- ciently large to prevent strangulation, leaving a portion on the back of the arm uncased by the ])laster. The arm is then drawn downward and back- ward until the clavicidar jiortion of the pectoralis major muscle is put suf- ficiently on the stretch to overcome the sterno-cleido-mastoid, and thus pull the inner portion of the clavicle down to its level. The plaster is then carried smoothly and completely around the body, and pinned to itself on the back to prevent slipping, as seen in Fig. 89. Tlie first Fig. 89. Savre's adhesive-plaster dressing for 'fracture of elaviele (first piece}. Ihe same (secund piece). strip of plaster fulfils a double purpose : first, by jiutting the clavicular portion of the ])ectoralis major muscle on the stretch, it prevents the clavicle from riding upward ; and secondly, acting as a fulcrum at the centre of the arm \\-hcn the elbow is pi'essed downward, forward, and inward, it neces.sarily foi'ces the other extremity of the humerus (and with it the shoulder) upward, outward, and backward ; and it is kept in this position by the second strip of plaster, which is applied as follows : Commencing on the front of the shoulder of the sound side, draw it smoothly and diagonally across the back to the elbow of the fractured side, where a slit is made in its middle to receive the projecting olec- ranon. Before applying this plaster to the elbow an assistant shouhl ]>ress the elbow Avell forward and inward (Fig. 90), and retain it there while SPECIAL FRACTURES. 581 Fig. 91. the plaster is continued over tlie elbow and forearm (pressinfj the latter close to the chest and .securing the hand near the opposite nipple) ; cros.s- ing the shoulder at the place of beginning, it is there secured by two or three pin.s, as seen in Fig. 90. "When this has been done the dcfurniity will have entirely disappeared, the fractured bones will be accurately adjusted, and as long as the strips of plaster maintain their position no amount of force can displace them." Velpeau's dressing is made by means of a long roller bandage. The patient's hand is placed upon his opposite shoulder, the elbow against the front of the chest, and a bandage is started in the opposite axilla and carried obliquely across the back over the affected shoulder (Fig. 91), down in front of tlie arm, and under the elbow tn the other axilla. After the arm is thus vertically bandaged and brought snugly against the chest, the roller is carried in a circular manner around the thorax from below upward until the arm and the forearm are cov- ered by this bandage as high as the axilla on the unaffected side per- mits. Tills entire dressing can be made stiff by the applit-ition of loose plaster or silicate of soda, or even by stitching it in many places, so that tlie roller will not l)ecome displaced by slipping. Moore's dressing consists of a figure-of-8 bandage (Figs. 92 and Fig. 92. Fig. 93. Velpeau's dressing for frac- ture of the clavicle. Jloore's dressing for fractured clavicle. Moore's dressing for fractured clavicle. 93), a detailed description of wiiich, in his own words, is: " T use a shawl or piece of cotton cloth, whicii, wlien folded like a cravat eight 582 FRACTURES. inches in bivndtli at tlie centre, slicmld Ite alxmt two yards long.

This twist, it will be seen, also makes the tigure (8) turn around the elbow of the affected side." Fracture of the scapula is rare, on account of the mobility of the bone, the elasticity of the ribs, the protection which is atforded to it by tiie cushion of muscles upon its dorsal surface, and the support which it has from the thoracic wall. Fractures of the scapula are caused usually by direct violence, although a case has been reported in which the fracture was said to have occurred as a result of muscular action. The varieties of fracture of the scapula are — fif the body, of the acromion process, of the coracoid process, and of the neck of the bone. When the body is fractured the line of fracture is usually just below the spinous process (Fig. 94). Fig. 94. Fracture of borty ot s( nimla. The signs and symptoms are — crepitus, pain, dis])lacement, and ecchymosis. The crepitus is found by placing the palm of one hand SPECIAL FRACTURES. 583 iipiin tlie back over the seapiila ami moving the arm witli the otlier hand. The chsphicement consists of the drawing upward and forward of the lower fragment by the action of the scrratus magnus and the teres major muscles, and the drawing backward and upward of the upper fragment hv the rhoml)oideiis major nuiscle. The treatment of fracture of tiie body of the scapula is tlie same as that described for fracture of the rib, with the addition of a compress over the body of the bone. The above-mentioned muscles causing the displacement should be relaxed by position. It has been suggested to place a gutta-percha mould over the bone, an! is rarely fractured. The accident is usually the result of direct violence. The apex of the process is jiulled downward ami inward by the action of the pectoralis minor, the short head of the biceps, and the coraco-brachialis muscles. It sometimes happens that little if any displacement is noticed, since the strong coraco-clavicular ligament remains untorn and the dense periosteal and fibrous tissue holds the fragments in place. Tile signs and symptoms consist of crepitus, mobility of the process, marked impairment in tlie movements of the arm, and the stationary position of tlie fragment when the arm is passively moved. The treatment consists in flexing the forearm ujion the arm, and then drawing well forward tlie elbow ujion tlie antero-lateral part of the chest. This position relaxes the two muscles having their origin from, and insertion into, the coracoid process.

Fracture of tlic nock of the scapula (according to Sir A.stley Cooper). Comniinutcrl fnu'tvirc of the cavity. enoid would cause a separation of the glenoid cavity only, while that of the surgical neck would involve the coracoid process. This fact must not be overlooked, since the disjilaeement in case of fraeture of the surgical neck is well jjronounced, wiiile tliere is little deformity if only the anatomical neck is fractured. The cause of this fractm-e is liy direct violence, either from a blow upon the shoulder or from a fall from a height in which the patient strikes upon the shoulder. The signs and s3miptoms eon.sist of a flattening of the shoulder, simulating a dislocation ; jii'ominence of the acromion, with a slight sulcus beneath it sufficient to receive the index finger placed laterally under it; lengthening of the arm ; the movement of the coracoid process with the humerus ; crepitus produced by elevation of the elbow and rota- tion of tiie humerus ; the eomj)lcte restoration of the landmarks of the joint by lifting the arm at the elbow, and their immediate loss ujion removal of the support ; and the presence of the glenoid cavity felt in the axilla. The treatment consists in elevation of the elbow after flexion of the forearm upon the arm, fixation of the i^cajtula by means of compresses held in place by strips of rubber plaster, and the adjustment of a pad in the axilla. The Velpeau dressing, as used in fracture of the clavicle, is an excel- lent dressing for this injury, since it supports the arm and causes lateral pressure of the arm to the chest-wall. P^RACTUREs OF THE HUMERUS form about 8 percent, of all fractures, and the classification is similar to that of fractures of the femur : in the U])per third, according to the seat of fracture, thus : fracture of the anatomical neck, of the tuberosity, of the surgical neck, and epiphyseal SPECIAL FRACTURES. 585 separation ; in the middle third, according to the variety of tlie fractnre, thus : simple, compound, cunmiinuted, and complicated ; in the lower third, according to the part fractured, thus : external and internal condyloid fractures, supra-condyloid fracture, and epiphyseal sejtaration. FradnrvK of f/ic Luirrr End of the Hninerun. — Epiphi/sca/ Sepani- tion. — Epiphyseal separation is likely to ha])pen Ijcfore the eighteenth year, and may occur in the form of a detachment of the articular extremity from the diaphysis. The condyles remain attached to the shaft, since they undergo ossification by separate centres, or the condyles witli the articular extremity may become detached from the shaft of the humerus. In some respects e]Mphyscal se|)aration resembles a supra- eondyliiid fracture or a backwanl dislocation of the forearm. In incom- plete epiphyseal separation the forearm is Hexed, and assumes a position midway between supination and pronation, while the normal relations which exist between the condyles and the olecranon are destroyed. The measurement of the forearm reveals shortening between the condyles of the humerus and the styloid processes of tlie radius ami the ulna. In the eomitlete epi])!iyseal separation tlie relations which exist l)etween the condyles and the olecranon are not disturbed, since the separation occurs above the condyles. The differential points between the fi'actures in this region on the one hand, and a backward dislocation of the forearm on the other, are the tendency of the deformity to return in fractures as soon as reduced, and the ditfieulty of maintaining perfect apposition even with suitable splints; also the preternatural mobility, crepitus, shortening of the arm from the acromion to the condyle, and more or less rigidity of the muscles, with ecchymosis over, and swelling in, the elbow-joint. A dislocation of both liones of the forearm backward is distinguished from epiphyseal separation by immobility, absence of crepitus, no altera- tion in the length of the shaft of the humerus, the great prominence of the olecranon, which is nearer to the acromion than upon the opposite side, and the greatly altered relations of the olecranon process and the condyles. The treatment of epiphyseal separation is the same as that of supra- condyloid fracture, since the two injuries require practically the same kind of surgical dressing. Svpni-coiithihiid fr<(rii(iT is usually trans- verse, but it is at the same time oblique from above downward and forward. The signs and symptoms are in some respects similar to the l)ackward displace- ment of both bones of tlie forearm (Figs. 97, 98, and 99). The diagnostic signs of supra- condyloid fracture 'are the ])rojection of the olecranon, the swelling in front of the elbow- joint, slight flexion of the forearm, prona- tion of the hand, and inability to flex the fore- arm. Marked crepitus is elicited by flexion and extension of the forc- ami. The signs which distinguish this injury from dislocation of both bones of the forearm backward have Iteeu enumerated in connection with ejiiphyseal separation. It sometimes luippens that a vertical frac- FiG. 97 Supra-eondyloid fracture of the hnmenis (Hutchinson). 586 FRACTURES. ture occurs in connection witli tlic sii])rn-con(lyloi(l fVacturc, in which tlie line of" fracture extends downward between the two condyles, forming what is called a " T-sliaped fracture" (Fig. lOOj.

The additional .signs of this complication consist of an increase in the breadth of tlie condyloid extremity of the lower end of the humerus and .severe joint-inflammation attended with great effusion.

Some surgeons advise the use of the internal angular splint with the forearm placed midway between jironation and supination and the ])alm of the hand pointing inward and the thumb upward. Passive motion sliould not be em])loyed until tiie end of the fourth week, as the fracture does not extend into the ell)ow-joint, and such movement before consolidation has taken place is likely to disturb the union of the fragments. Internal condi/loid fractior occurs as a result of direct violence, and the line of fracture generallv extends downward and outward to the tro- SPECIAL FRACTURES. 587 Fracture of the inter- nal epicondyle of the hiimer\is (epi- trochlea) (Gurlt). chlear surface of the Immerus, and passes throuo-h the olecranon and coronoid fossae. Tlie fragment is displaced upward and backward and slightly inward, and it is accompanied by the ulna. The signs are — removal of the internal condyle from its normal position, crepitus, moljility, pain and swelling over the internal condyle, increase in tiie breadth of the lower end of the humeriis Fig. 101. (Fig. 101), greater prominence of the ulna posteriorly during e.xtension of the forearm, and a corresponding swelling upon the front of the elbow-joint, due to the projection of the lower end of the humerus. The treatment of this fracture consists in the apidi- cation of some evaporating lotion over the condyle and the joint with a view to reducing the inflammatory swell- ing. As soon as the inflammation has subsided the frag- ment, consisting of the internal condyle, should be jjlaced in its proper position, and held //( xitu l)y niean-^of a pad. An angular s))lint Fig. 102. siionld now be applied, with the fore- arm flexc'l upon the arm to a right angle and placed in the position of supination, or midway between pro- nation and supination, with the thumli upward. In the use of an angular splint tlie surgeon must guard against any undue pressure, which might cause a slougii over any bony prominence or even gangrene of the Angers. Since this fracture involves the elbow-joint, passive motion must be instituted after the second week in order to prevent ankylosis. In ease the fracture is T-sha]ied, cold evaporating lotions should be first ap- plied, and after the subsidence of the inflammation the fragments should be adjusted and the same kind of splint applied. Ankylosis follows, since no passive motion can be made, and the degree of ankylosis de- pends upon the amtnuit of joint-complication. External condi/loid fracture is often .seen in chil- dren. While it may be the residt of direct violence, it is more often caused by a fall upon the hand. It usually involves the elbow'-joint, or the fracture ex- tends downward and sejwrates the capitellum from the artictdar surface, and the liead and shaft of the Showing the transmis- ,. ] . • i ^1 -i 11 rni sion through the ex- racluis are driven up against the ca])itciliim.

I The treatment of this fracture is similar to that employed in fracture of the internal condyle, so tliat a separate description is unnecessary. Fracture of the shaft of the humerus is frequent- ly observed, and it is produced by direct as well as by indirect violence, and even by muscular action, and, again, bv uterine contraction. It has been produced during the act of parturition. The lower half of the bone is more frequently broken tiian tlie upper half, and the line of fracture is generally oblique from al)ove downward and outward. A transverse fracture is more frequent in the Inuiierus than in the other bones. Fractures involving the shaft include all below the surgical neck to the con- dyles of the bone. Tlie displacement in fracture of the siiaft of the humerus largely depends upon its situation in refer- ence to the attaclnnent of tlie deltoid muscle. If aljove the insertion of the deltoid and below the insertion of the pectoralis major, hitissimus dorsi, and teres major, the lower fragment is found to lie external to tlie ujiper fragment and is drawn upward by the deltoid nuis- cle, while the upper fragment is drawn inward by the action of the pectoralis major, latissimus dorsi, and teres major muscles. If the fracture takes place below the insertion of the deltoid muscle, the lower fragment is drawn to the inner side of the upper fragment by the action of the triceps and biceps muscles, and the The outward deflection upper frajrment is abducted by the action of the del- of the forearm— the , '.', i^, ,, ,. -i p i i ii "carrying function." to id, and at the same time drawn torward by tlie an- SrECFAL FRACTURES. 589 terior fibres of tlie deltoid and the pectoralis major. There is very little displaeement in fractures of the shaft of the humerus in the lower j)art of the bone, since the broad insertion of the brachialis anticus in front is counterbalanced by the insertion of the triceps behind. These two muscles so completely surround the shaft of the humerus that little or no disj)lacement occurs. The signs and symptoms of fracture of the shaft of the humerus consist of pain and swelling, with eeehymosis at the seat of frai'ture, crejiitus. false poiut of motion, shortening of the arm, and complete loss of function. The treatment of fracture of the shaft of the humerus depends upon the special seat of the fracture. As a general rule, the best dressing, if there is only sligiit displacement, is a bandage of plaster of Paris ajiplied over a layer of absorbent cotton. The bandage must include the ticxetl forearm as well as the arm, and then form a spica over the shoulder. In ease the Fi|ili!]l, Clark's extonsinn in fracture of the neck of the hunieru.s. In s])ecial cases, requiring greater extension to overcome the deformity and to maintain the ap]i(isiti(jn, the surgeon can employ an extension apparatus by means of adhesive jilaster applied from the upper end of the lower fragment to the elbow-joint, and from the cross-piece below the joint attach a bag of sand, as suggested by Clark (Fig. 106).

In fractures of the shaft there is danger of non-unittn, and also some danger of gangrene of the fingers from too tight bandaging or from too great axillary compi-ession if s})lints or pads are employed. If the radial artery cannot be felt at the wrist, no bandage or splint should be employed, since its application migiit be considered as the cause of gangrene. There is also an additional danger of subsccjueiit paralysis of the mu.s- cles presiding over supination of the forearm and extension of the hand and fingers, causing pronation of the hand and wrist-drop. This may occur as a result of injury to the nmsculo-spiral nerve (Fig. 107), or in conse(juence of an exuberant callus which enslieaths and compresses the nerve (Fig. 108). In the latter case the nerve can be tunnelled out after the fracture is re- paired (Fig. 109), or in some cases the two ends of the divided nerve may be found and sutured. In fractures of the humerus Stromeyer's cushion (Fig. 110) is often of great service if for any reason the fracture cannot be placed permanently in a retentive apparatus.

Fracture of the tuberoftitj/ of the shaft occurs as a result of direct vio- lence. The iintero-posterior diameter of tiie joint is increased, and there is a sulcus found between the front of the joint and the fragment, which Fi(^ 112. /\ Separation of the upper epiphysis of the humerus (R.

Smith). is drawn upward and abducted by the external rotators, giviuw tiic slioulder a peculiar contour, described by some authors as trumpet- shaped, on account of the double tumor, one under the acromion, and the other under the coracoid process. There is a well-marked depres- sion just beneath the acromion process, and crepitus is easily obtained by rotation of the shaft with the fingers holding the sejiarated tube- rosity. The rotation of the humerus siiows no impairnuiit in the move- ment of the head of the bone in the glenoid cavity. The treatment of fracture of the tuberosity consists in making the .shaft of the bone adajjt itself to tlie detached tuberosity. This is best aeconi])lished by a pad in the axilla, whicii throws the ujtper end of the bone outward. The elbow sluaild be l)rought to the side of the chest- wall and the forearm suspended in a .«ling. A pad should lie placed behind and above the tubercle after it is reduced, so as to prevent it from slipping upward and backward by the action of the rotators attached to the fi'agmcnt. Fracture of the .surgical ucck is situated outside of the capsule of the joint, and corresponds to the extra-capsular fracture of tlie cervix fenio- ris. The line of fracture is l)elow the tul)erosities, but above the inser- tion (Fig. 113) of the pcctoralis major, latissimus dorsi, teres major, and deltoid muscles. SPECLiL FRACTURES. 593 Fig. 113. P'rat'ture of the surgical neck of the humerus. The displacement consists of an external rotation and abduction of the upper fragment, caused by tlie action of the muscles inserted into the greater tuberosity— viz. tlie supra-spinatus, the infra-spinatus, and the teres minor muscles — while tlie shaft of the bone is drawn upward into the a.xilla by tlie action of two of the three muscles which take tiieir origin from the coracoid process — viz. the bice])s and the coraco-bracliialis muscles — and inward by the action (if tlie peetoraiis luajor and the teres nuij(ir muscles. Tlie signs and symptoms are — absence of rotation of the head of the bone with the shaft, while at the same time the head of the bone remains in the glenoid cavity ; shorten- ing of the arm to the extent of al)out one incli ; crepitus, unless the fracture is im- pacted ; swelling, pain, and ecchymosis ; al- teration in the a.xis of tiie bone, wliicii is di- rected downward and outward ; and a pecu- liar flattening of the shoulder just Ijclow the acromion. This flattening is not so marked as ill dislocation, but more so than in fracture of the anatomical neck. The treatment consists in the application of a plaster-of- Paris bandage, which includes coaptation splints to the broken arm and a spica over the shoulder, with the forearm flexed to a right angle, and the eiiiploynient of tlie axillary pad. In case the fracture is attended with mucli deformity, a splint in tlie form of a triangle lias been employed with great success, since the apparatus makes the shaft adjust itself to the upper fragment. If it is unnecessary to employ the triangle, the elbow should be carried well forward and brought close to the side of the body ; which position has a tendency to overctime the inward displacement of the shaft. Fracture of the anaioutiatl ncch is produced tiy direct violence, as in a gunshot wound or by a fall upon the shoulder. The fracture is within the capsule of the joint, and corresponds to the intra-capsular fracture of the cervix femoris. The fragment receives no lilood-supply,and is prone to undergo necrosis and to establish sujijiuration in the joint. Union may result if iiii]iaction is present, and for this reason any attempt roughly to niaiiipulate the fracture with a view to a diagnosis may be attended with serious results. The displacement is very slight, if any, owing to the peculiar anatomical conditions. The signs and symptoms consist of a prominence of the acromion and flattening of tiie shoulder, both of wjiich, liowever, exist only to a moderate degree; shortening of the arm to the extent of about half an inch, with pain, swelling, and crepitus, unless the fracture is impacted ; and absence of ecchymosis, since the fracture is within the <-a])sule. The treatment consists in the ajiplication of evaporating lotions for a few days to control the inflammation in tiie joint, and afterward in the adjustment of a felt or plaster-of-Paris shoulder-cap and a ])ad in the Vol. I.— 3S 594 FRACTURES. axillii.

FiiACTUREs OF TiiK FOKKAKM may bc divided into fracture of the coronoid or olecranon process of the ulna, of tiie shaft of the ulna, of the styloid process of the ulna, of tlie liead and neck of the radius, of the shaft of the radius, of the lower end of the rark. Tiie dorsal proniiuence is due to the riding ujiward and l)ackward of the lower fragment witli tlie carpus, while tjie palmar deformitv is produced by a projection forward of tiie lower end of the upper fragment, which is pronated by the action of the pronator quadratus and pronator radii teres muscles. The internal lateral ligament is generally torn out of its inser- tion into the styloid process, and Moore has demonstrated tliat the process becomes entangled in theanuidar ligament. Tlic lower end of the up]>er fragment is generally driven into the upper end of the lower fragment by the continuance of the same force that originally caused the fracture. This impaction of the upper fragment, consisting of compact bony tissue, into the lower fragment, formed of cancellated tissue, explains the frequent absence of crepitus in the fracture (Fig. 1 17). The signs and symptoms of fracture of the lower end of the radius are — inability to sup])ort the firearm, the position of the hand midway 596 FR A ('TUBES. between pronation and su|iiiiatii)ii, the flcxidii of (lie fingers, the silver- fork deformity, tlic great |)r(»iiiiiK'nce of the styloid process of tiie uhui, Fig. 117 CoUes's fracture: union with persistence of displacement (Smith). the loss of snpination and pronation, severe pain, and often swelling due to eifusion into the sheaths of the tendon. The treatment of this fracture consists in overcoming at once the deformity hy prom])tly reducing the fracture and tiien retaining the fragments immovably fixed in tlieir proper j)ositiou. The reduction is made by the surgeon grasping the hand of the patient as if to shake hands with him, and tlien making forcible continut)us and gradual extension, so as to disengage the impaction and bring the lower frag- ment into apposition with the upper. The surgeon should place the thumb of the left hand against tlic styloid process of the ulna and push it around, so as to bring it into its normal ])osition. In some cases it may be necessary to administer an ana'.sthetic in order to reduce sati.s- factorily the deformity. The fixation of the adjusted fragments can be maintained by several dift'erent forms of splints. The best dressing is by two lateral splints, which should be well padded and broad, and extend from the extreme u]iper end of the fore- arm to exactly the lower margin of the lower fragment, and leave the wrist-joint free. The forearm should then Ix- placed in a sling, so that the hand falls downward and is adducted by its own \veight, in M'hicli Fin lis.

Gordon's apparatns consists of two pieces, a palmar splint (Fig. 118) constructed so as to overcome the forward displacement of the fragment bv the addition of a conical piece, whicii produces jiressure upon the lower end of the ujiper fragment, and thus has a tendency to elevate it, while the hand itself raises the lower fragment. The other splint is applied to the dorsal surface of the ftirearm, and by its thick padding over the wrist has a tendency to overcome the deformity. Carr's apjiaratus (Fig. 119) consists of a palmar splint padded so as to obliterate the depression over the radius. To the extremity of this Fm. 119. Carr's spliut for a loft CuUes fracture. palmar splint is attached an oblique vertical piece, and on this round bar the fingers are flexed. This palmar spliut is supplemented by a second or dorsal splint. Bond's apparatus (Fig. 120) consists of a splint made of a piece of wood, to the lower extremity of which is fixed a curved block which Fig. 120. Bond's splint. should fit the hollow of the palm in order to give support to tiie hand and fingers. The splint should be well jiadded, so as to fill up the con- vexity of the radius on its palmar side. In conjunction with the palmar splint a dor.sal splint is used, with a compress so adjusted as to etl'ect the reduction of the lower fragment. A fracture consisting of a chipping off of the posterior liji of the articulating surface of the radius has IjCen described by Barton, after whom the fracture is named. The fracture clinically requires the same treatment as that indicated for Colles's fracture. Fracture of flic xhaft of the radinH occurs by direct violence, as a blow upon the forearm, or by indirect violence, as a fall u])on the hand. As a rule, however, a fracture of the radius caused by a fall upon the rm FRACTURES. Fracture of the radius liaiid is situated in tlic lower end, Imt occasionally this injury causes a tVaetiire of the shaft of the hone. The displacement in fractures of tiie shaft depends u]ion the situation of the fracture, since the deforniity varies accordinti; to wlicther the frac- ture is above or below the insertion of the pronator radii teres muscle. If the fracture is above the insertion of this muscle and below that of the biceps, the upper fragment is strong'ly supinated and flexed, while the lower frafi-ment is ]ironated Ity the pronator radii teres and the pro- nator (juadratns. Tliis displacement is not very ap])arent, on account of tile anatomical conditions; but if union takes place without correcting the deformity, fusion of the bones occurs and the movements of prona- tion and supination are lost ; and this movement can only partially be accomplished by the shoulder. If the fracture is situated below the insertion of the pronator radii F'f-- 121. teres, this muscle oj)poses the action of the biceps ;ind the supinator brevis, so that the forearm remains in a position midway between pronation and supination (Fig. 121). The supinator longus below o])poses the feeble action of the ])rona- tiir ((uadratus. Tlie disjdacc- ment consists of slight flexion of the upper fragment by the biceps and pronation by the pronator radii teres, and a drawing inward of the lower fragment by the pronator (piadratus, assisted l)y the supinator longus, which by traction of the lower end of the lower fragment tilts the upper end of the lower fragment toward the ulna. The signs and symptoms of fracture of the shaft of the radius are those usually found in any fracture, such as pain; talse point of motion; and crepitus, which in this special fracture is elicited by rotating the hand while the surgeon places his thumb on the head of the radius, or by indentation of the two broken ends at the seat of fractiu'c. The treatment varies according to the seat of the fracture. From a careful study of the dis])lacement when the fracture is above the inser- tion of the pronator radii teres, it is evident that the forearm must be strongly supinated in order to bring the fragments into accurate apposi- tion. For this purpose it is necessary strongly to supinatc the forearm. Tills can be done by placing tiie jwticnt in bed and stretching his arm out at a right angle from the trunk, and allowing the supinated arm to rest upon a hard cushion ; or, if the patient is unwilling to be confined to the bed, the forearm can be flexed to a right angle with the arm, and a splint applied to the arm and forearm (Fig. 122), so that the palm is directed upward. If the fracture is below the insertion of the pronator radii teres, tlie application of two lateral splints can be made, with the forearm midway between pronation and supination. Some surgeons recommend that the sjilint extend only to the wrist-joint, but if there is much mobility it may be well to have the splint extend below and sup- port the hand, since there is no tendency for the wrist-joint to become SPECIAL FRACTURES. 599 ankylosed. A small strip or pad down the centre of the splint has been suggested, so as to separate the radius and ulna to prevent au}- union Fig. 122.

Fntcfurc of the hnifl (uifJ neck of the nifliiix I'arely occurs, except in connection with a dislocation backward of both bones of the forearm or witli a fractiu'c of the coronoid process of the ulna. The fracture may be, however, occasionally observed as the result of a gunshot injury, or it may be jirescnt in the form of a compound fracture, in M-hich ca.se the head and neck are usually sijlintercd in the long axis of the bone (Fig. 123). It is some- times found to be comminuted. The signs and symptoms are inability to pro- nate or supinate the forearm ; crcj)itus at the .seat of fracture, elicited by seizing the patient's hand and proiiating the forearm while the thiiml) of the surgeon's otlier hand is placed over the orbic- ular ligament; the presence of an unnatural bony prominence at the in.sertion of the biceps, due to the Hexion and supination of the fragment by the action of this muscle ; the presence of ecchy- mosis and localized pain ; and the jieculiar position Fracture of neck of rajius. of the forearm, wliich is pronated. The treatment consists in placing the forearm in a position of extreme flexion, which relaxes the biceps, which tilts forward the frag- ment. A compress should be applied to the fragment in order to keep it in position, and the limb bandaged to an angular s])lint. Care must be taken not to produce any compression upon the brachial artery while the forearm is extremely flexed, lest the circulation be disturbed and gangrene ensue. Passive motion must not be practised until the fragment is well united, lest the biceps, contracting during forced extension, might separate the fragment. If there is great tend- 600 FRACTURES. ency for the fragment to become flexed and supinated by a rigid con- traction of the biceps, tenotomy will iniincdiately overcome the deform- ity, and the parts will be at once adjusted. FracUiir of tli<' sti/loid jtronns of the iiliKt occurs as a result of direct violence. The fragment is distinelly felt just beneath the skin. The signs and symptoms are too a])parent to require any special description. The broken fragment should be manipulated until it is brought into its proper position, and then maintained there by the use of a compress which is held firmly in n'tiu by strips of rublx'r jilaster. It is advisable to keep tiie wrist- and elbow-joints at rest for a short time until the fragment tmites, as any movement of these joints has a tendency to displace the broken part. Fracture of the shaft of the ulna occurs as a result of a fall, or in boxing, in warding f)ff blows aimed at the face, and its seat is usually just below the midille of the bone, since at this point the bone is not so thick and is less protected by a cushion of muscles. The displacement is caused by the action of two muscles — viz. the brachialis anticus, wliich has a tendency to flex the upjier fragment, and the pronator quadratus, which has a tendency to abduct it and thus draw it toward the radius. The signs and symptoms are localized pain, tenderness, and ecchy- mosis, the presence of a tumor, the existence of crepitus and great mobil- ity. The finger, if passed along the sliaft of the Ixme, will usually detect the fracture, as the bone is quite superficial in the lower half of the shaft. The treatment consists in the application of two broad lateral .splints from the ell)ow- to the wrist-joint. Before adjusting the splints the broken ulna should 1)(> forced away from the radius, so as to jtrevent any fusion of the bones of the forearm, which would impair pronation and supination. The forearm should be flexed at a right angle in order to relax the brachialis anticus, which has a tendency to tilt forward the upper fragment, and also be placed midway between pronation and supination. The forearm sliould be carried in a sling, and the lateral splints should be broad enough to prevent any pressure upon the broken bone, which pressure would have a tendency to cause fusion of the two bones of the forearm. Fracture of the coronoid and olecranon processes of the ulna occurs as a result of a fall upon the back of the elbow during semi-flexion of the forearm, or by muscular action. Fracture of either process is seldom seen in a person under fifteen years of age. Fracture of the coronoid process usually occurs as a comjilication in backward dislocation of both bones of the forearm, whicli acciilcnt is usually the result of a fall upon the palm with the elbow-joint partially flexed. The fracture has been observed as a result of muscular action in attempts to lift the weight of the body with the hand or in grasping by the hands an object in the act of falling from a height. The sig-ns and symptoms are backward dislocation of botli bones of the forearm, the presence of crepitus, the existence of a bony prom- inence in the transverse fold of the elbow-joint, and a tendency to return of the deformity after reduction. The treatment consists in placing the forearm in an extremely SPECIAL FRACTURES. 601 flexed position to relax the brachiali.s antieus muscle, and applying an angular splint with an aligle adapted to the position. II' the fragment persists in becoming displaced, it can be wired to the shaft. In such au operation the close proximity of the brachial artery must not be over- looked. Unless the fragment is sutured, the union is likely to be liga- mentous, and passive motion should bo instituted after three weeks iu order to preserve the mobility of the joint. Fracture of the olecranon jyrocess of the ulna occurs during adult life iind seldom before the fifteenth year. The fracture is the result of direct violence, either from a blow upon the process or by a fall upon the part when the elbow-joint is flexed to a riglit angle. This fracture also occurs by muscular action, as in sudden I'ontraction of tlie triceps dur- ing extension of the forearm. The mechanism of fracture by this cause is tliat of a lever across the condyles t)f the humerus. The signs and symptoms are — well-marked depression at the back of the elliow-joint, produced by the action of the triceps in drawing upward tiie fragment ; the presence of crepitus, elicited by flexing and extending the forearm ; abnormal mobility of the fragment; tiie exist- ence of synovitis of the elbow-joint ; the stationary appearance of the fragments ; and the separation of the shaft of the ulna from it during extension. The treatment consists in placing a compress over the fragment after it has been reduced, and applying a strip of adhesive plaster to keep the fragment innnovaljly fixed to the shaft of tlie ulna. A straight splint which is M-ell padded should now be adjusted to the arm and forearm upon their anterior surface, with the limb in an extended position. If the fragment cannot be kept iu place, sutui"iug it to the shaft is indicated. This operation must be done with every aseptic pre- caution, since the wound conununicates with the joint. If the fracture is compound, suturing is indicated, and at the same time free drainage of the joint for a few days must be employed. If for special reasons suturing is not advisable and a stiff joint is likely to ensue, the fore- arm should be placed midway between flexion and extension, since this position renders the upper extremity more serviceable than the straight position, whicli gives the patient practically a useless arm. Fracture of the carpal bones is rare, and occurs, as a rule, from direct violence. Owing to the strong ligaments which hold the carpal bones together, there is little displacement. Fractures of these bones are often overlooked on account of the extensive damage of tlie soft parts and the consequent swelling of the wrist-joint. There is very little dis])lacement, owing to the anatomical arrangement of the wrist articulation. Tlie sig-ns and symptoms are crepitus, swelling, pain, and loss of function of the joint. The treatment consists in placing the hand upon a long palmar splint, at the smne time ajiplying over the injured part warm fomenta- tions or cold evaporating lotions until the acute inflammation has sul)- sided. In severe contusion of tlic soft parts without wound the warm applications are best suited, wliile iu severe inflammatory reaction unac- companied by external wound the cold lotion is indicated. Absolute rest, a moderate amount of compression, and an immovable splint to give 602 FRACTURES. support to the liantl, \vi"ist, and ibroarm are required. \\'hen tlie signs of acute inflaiiiniation have di.sapj)eared, a splint shouhl he a])iilied, and passive motion bcnuu after a fortniglit in order to preserve the motion of the joint. If the fraeture is ('ompound, the loose fragment must bo removed, the joint thoroughly irrigated, and a drainage-tube passed through from the dorsal to the j)almar surface, and antise})tic dressing.s applied together with a splint. Firictures of the iiwtacarjMtl honefs are common, and are usually the result of direct violence. On account of tiie exposed jxisition of the first metacarpal bone, it is found to l)e tiie one most fre(piently fractured, and after it, next in point of frequency, the second, \vhilc the third is less frequently broken than the others. The ujjper fragment is usually disjilaced downward toward the ])alm of the hand, owing to the action of the interosseous muscle and the natural shape of the shaft of the bone. The signs and symptoms consist of crepitus, pain, swelling, inter- ruption of the continuity of the shaft of the bone, prominence in the palm of the hand due to the presence of the distal end of the proximal fragment, the dropjiing of tlie knuckle, and the depression on the dorsum due to tlie falling down of the two fragments. Tlie treatment consists in jilacing tiie hand upon a long palmar splint extending from the elbow to a point biyond the tingers, with a pad over the seat of fracture on the palmar surface of the hand, or by flexing tlie hand over a ball, so as to push up the displaced fragments by mechanical action and by extension of the fragments, and at the same time ap])lying the long splint. Too much importance cannot be attached to the conservative treat- ment of compound fractures of these bones. The parts are so vascular, and the retluction of the fragments so easy, that it seldom becomes necessary to perform amputation if proper antiseptic precautions are emploved. The fragments should be wired if greatly displaced, or some of the connninuted pieces should be removed and the periosteum left, or even transplantation of the bones can be accomplished when the necessary conditions are present. In Figure 124 is shown the result obtained in a case of a compound, conmiinuted, and complicated fracture of the second metacarpal bone and the two phalanges of the thumb. As the two phalanges of the thumb were spontaneously ampu- tated l)y machinery at the time of the accif first and second phalanges of the thuml), and excision of the metacarpal bone of index linger; transplantation (jf metacarpal bone of the thumb to the index linger. which, as well as of similar results from other causes, is seen in the accompanying plate (Fig. 12">). The treatment of simple fractures of the phalanx consists in restor- ing the fragments to their proper place and holding them in sift} by means of a gntta-jtercha, jxisteboard, metal, or leather splint, accurately moulded to the corresponding finger of the opposite hand, and then aj)plied to the injured and extended phalanx. In addition to a s])lint directly applied to the fractured part, a long splint should extend from the palm of the hand to the tip of the linger, so as to keep the frag- ments inmiovaljly trical manipulation in a case of ditiicult labor. Congenital dislocation may also result from disturbance of the nervous centres, as in spastic contractions of the muscles, in infantile paralysis, and in pseudo-hyper- trophy. A congenital dislocation is not always recognized at the time of l)irth, and often not until the child makes attempts to walk. The hi]), shoulder, knee, ankle, patella, tarsus, and phalanges are among the joints and bones that are most frequently the seat t)f this special variety of dislocation. The pathological dislocation, as its name implies, is one produced as the result of (lisease. This variety is seen during the progress of morbus coxarius, and also in chronic disease of the knee-, ankle-, and other joints. The joint disease produces absorption of the head of the bone with destruction of the capsule, and the entire cavity and the head of tile bone become more or less oblit- erated (Fig. 128). Another variety niav occur as a result of reflex muscu- lar contraction from disease of the spi- nal cord, and in tiiis variety a distinc- tion must be made from the preceding |iatliological dislocation, since tlie joint itself is not the seat of bone disease. This same variety may also occur in the course of certain fevers, as typhoid, or articular rheumatism : suddenly the joint, usually the hip, Ijccomcs dislo- cated, the ca])sule having ruptured from over-distention. The traumatic dislocation, which is due to external violence, may oc- cur in almost any joint in the body. The injury may result in either a complete or an incomplete luxation of the joint, the special form of which depends upon the amount of vio- lence exercised, together with the peculiar anatomical conformation of the joint. Kronlein has demonstrated that about 90 per cent, of the traumatic dislocations affect the upper exti-emity, while only about 5 per cent, involve the lower extremity, and the remaining affect the trunk. The ages between twenty and forty are the periods when traumatic dis- locations are most frequently observed. Pathological dislocation of the hip-joint. DISL CA TIOKS. 60 7 Tlie pathology oi" clislocation involves miicli more tlian the mere luxation of tlie joint, since in every case the injiirv not only affects the articiilatin<>' surfaces, hut in addition the liiianicnts are torn, the muscles are lacerated, the cartilages are contused, the arteries are ruptured, the nerves are stretched, and the fascia emhracinii- the joint is torn away from its attachment. In compound dislocation the skin is broken and usually destroyed, while the larger vessels are often torn. It is thus evident that a dislocation is a serious injury, and if it happens to affect a large joint and is compound in character, it involves life itself, and in all cases aff'X'ts to a greater or less degree the future usefulness of the joint. In gouty, syphilitic, tubercular, or rheumatic persons a dislocation of a joint is often tlie starting-point of a chronic su|)pnrativc arthritis, wiiich assumes a peculiar type according to the diathesis, and leads eventually to resection of the joint or even amputation of the limb. In dislocation of the shoulder, occasionally, the branches of the axillary, or even the axillary itself, are wounded, either bv rujHure of the middle and internal coats or by rupture of the three coats sim- ultaneously. If the former has occurred, an aneurism slowlv develops, while if the latter has occurred, a rapidly-growing traumatic aneurism develops, with signs of collapse and gangrene of the extremity. This same condition may obtain in reference to the popliteal vessels in dislo- cations of the knee. The management of such ancimalous cases includes reduction of the dislocation and an operation for the inuuediate relief of the hicmatonia. This latter operation is to be performed according to the rules governing the methods of treatment discussed under Aneurism. Large nerve-trunks may be injured as a result of a dislocation. The jiaralysis may be due to pressure owing to the presence of blood or bone. This disturbance of function in the nerve disappears after alisorption of the extravasated blood and removal of the bonc-ju'csstirc. The ])aralvsis may be due to laceration of the nerve, wliich condition is not likely to disappear, or it may be caused by injury during attempts to reduce a dislocation. A neuritis, or even traumatism of the nerve-trunk, may cause a paralysis, and this condition result from the same injury that produced the dislocation. In investigating a dislocation the possibility of injury to internal organs must not be overlooked. The pelvic organs in disliicatiiin of the hij), and the wsojihagus in dislocations of the clav- icle, are often tiie seat of injury which leads to distui'bance of function or destruction of the organ or viscus. In considering the signs of dislocation it is not inappro]iriate to compare tiiis injury with fracture, which is usually a less serious acci- dent. In dislocation the sliaft of the bone belonging to the affected joint is not shortened, though the entire limb may be shortened. In dislocation there is alisence of mobility, and hence the false point of motion, which is so characteristic of fracture, is absent in dislocation. There is no tendency for a dislocation to r"turn after reduction unless further vio- lence is exerted, while the deformity is likely at once to reappear in a fracture left to itself. In dislocation there is often present a kind of crepitus wliich nuist not l>e mistaken for tliat of fracture. The crepitus found in dislocations is of a peculiar kind, and is not bonv unless a frac- ture coexists : it is due to blood-clots, lymph, ov albumin, and in .some cases to a roughening of joint-surfaces. 608 DTST.OCATIONS. In tuircdvcrd dislocation the result varies according to the ]ioint In- volved and tiie extent of the injury. Jn the hip and ankle and tlu; shoul- der and elbow changes occur throngli the efforts of Nature, by means of which often a most serviceable joint is constructed. The connective tissue undergoes a certain amount of condensation, and mechanically jirevcnts the ho>ad of the disj)lacc(l lionc from fai'thcr receding troni its new posi- tion. The active use of the new joint causes a certain amount of absorp- tion of bone, and makes the globular iiead move with comparative free- dom in its newly-made socket. The irritation set up causes proliferation of the connective tissue, which is soon transformed into fibrous tissue, and around the head of the bone a comjjlete wall is thus formed, the inner side of which is lined l)y flat cells which secrete a small amount of Huid, which in tui'u serves to lubricate the new joint-socket. Often some part of the synovial membrane is torn away, and if nourished con- tinues to secrete some synovia. The changes which occur in the bone and its coverings are of interest to the pathologist, since the periosteum often produces bone and the fibrous tissue undergoes ossification. The pressure of the head of the bone on the periosteum, whicli is not de- tached from the bone, causes it to inflame from continual irritation, and thus new bone is develoj)ed to aid in the formation of a bony cavity for the reception of the displaced head. During these changes tlie original joint-socket becomes gradually obliterated by a process of absorption and by the development of granulation tissue in the bottom of the cavity. A study of all of these changes in the new socket, in the head of the bone, and in tlie original joint-cavity, with the Ijlood-vessels and nerves imbedded in the newly-formed infiannnatory tissue, teaches the import- ant lesson that the surgeon must not overlook the danger of attempting by violence to reduce old dislocations, since the risk of tearing vessels and nerves, and even of causing a fatal issue, is imminent. The causes of dislocation may be divided into predixpoxinf/ and e.reitinr/. Among the predisposing causes may be mentioned unusual freedom of movement in a joint, the male sex, the adult age of the ])atient, the arrest of joint-development, and senile or pathological absorption of the head of the bone with changes in the joint-cavity. Among the exciting causes may be mentioned mechanical violence and nmscnlar action. The signs and symptoms of dislocation are — disturbance of function of the joint, interference with passive motion, suulleys (Fig. 132), which can be used with a certain amount of ssifety in careful hands. Malgaigne has laid down the rule that no force beyond 440 pounds should ever be employed, and a Fig. 132. Bloxam's dislocation tournl- yuet. CVimpmmrl pulleys, and rini.' to which one end of llic i.uUcy-rope is fiistened. dynami)meter should be attached to the pulleys in order to ascertain tli precise amount of force exercised.

I' ' Clove-hitch (Ei-ii lison). M'ith comparative safety under the influence of an anipsthetie. Subcu- taneous division of tendons often aids the surgeon in the accomplish- ment of his object, aiid this simple operation caunot be too highly recommended. Too prolonged extension should never be employed, since serious damage can arise from this cause. No surgeon should continue perma- nent extension over twenty consecutive minutes. All adhesions should be broken up as far as possible before aj)plying the extending and counter-extending force, as this is often of signal benefit in antici|)ation of, and in conjunction with, the employment of forced extension. After a dislocation has been successfully reduced the joint should be immi)val)ly fixed for at least a week, after which time the dressings should be remlaster-of- Paris bandage supported with a few strips of tin or zinc to strengthen it. In three to five days a fenestruni should be cut, the joint again irrigated through the tube, which, if the temperature, pidse, and respiration are normal, can either be entirely removed or at least shortened, and finally removed at a sub- sequent dressing in forty-eight hours. This ilrcssing should be conducted witli the same antiseptic precautions and under continuous irrigation, pre- <-isely in the same manner as the initial dressing. The plaster sliould remain on for at least four weeks, and then gentle passive motion should be employed, and at the expiration of two additional weeks a limited amount of active motion should be permitted. If this plan has failed, suppurative arthritis ensues, and a secondary resection or amputation must be performed. Primary exci.sioii of the joint is the second plan of treatment when it is not considered best to attempt conservative measures. In this case the joint is widely opened, the loose pieces of comminuted bone are removed, the torn fascia is cut away, and the wound is rendered aseptic. In the shoulder-, elbow-, wrist-, and ankle-joints a movable joint should be secured, while in the knee an osseous ankylosis is probable. Primaiy excisions are very unfavorable as compared with secondary resections, and a ease of primary excision under these conditions gives rise to great anxiety. Pr'unari/ (iiiijiiitdtion is indicated where it is not best to attempt either a conservative j)lan or a primary excision, and therefore embraces a class of cases found in elderly persons in whom the joint is seriously damaged and the main vessels are torn. Dislocation of the ribs is seldom observed, since they have very limited motion and great elasticity, and are held together by strong lig- anicrits. Tiie ribs iii'ay be separated from the bodies of the vertebne in fracture of the spine, in which case the head of the rib is found lying upon the front of the .spine. The ribs may also be dislocated in con.se- quence of severe fills, or even blows upon the back, with or without fracture of the spine. The sig-ns and symptoms of this dislocation are obscure, and are generally arrived at liy exclusion. There is a depression, with no crep- itus, but with a peculiar grating sound, caused by the head of the rib ()U DISLOCATIONS. ridiiifi' on the front of the spine wlieii tlie rilj is pusiied from the front ; the pain is sometimes very severe. The treatment is substantially the same as it wouiti he in fracture of the l)oue. Dislocation of the c'ai;tila(;k.s from tiie sternum oeeurs especially in young people. The first rib, having no synovial capsule and true joint, is so protected that it is not liable to dislocation. The second to tile seventh ribs may become! dislocated at their junction with the sternum. The accident may be complicated witli fracture of the stei-num. CosTO-STERNAL Di.si/)CATiON may occur as a residt of a blow, or in consequence of a sudden violent com})ression of the chest, or even by muscular action. The sig-ns and symptoms are the presence of a subcutaneous tumor u[)on the front of the sternum, produced by the dislocated cartilage, and severe pain over the site of tlie injury. The treatment isists in reducing tlie tonis, and requires the same treatment. Dislocations of the clavicle occur either at the sternal or acromial end. These dislocations are extremely rare, on account of the strength of the short ligaments, and in this resjiect differ from frac- tures of the clavicle, which are exceedingly common. Dislocation of the clavicle at the sternal end may be forward, backward, or upward. The forward dislocation is caused by some violence ajqilied to the acromial end of the clavicle, by a fiill upon the front of the sliouldcr, or in liending the shoulder suddeiilv backward in certain gymnastic move- ments. The writer has seen a dislocation of the clavicle occur in playing lawn tennis. The dislocated end of the clavicle lies upon the front of the sternum just beneath the articular facet, and upon the sternal origin of the steruo-cleido-mastoid muscle (Fig. 134). SPECIAL DISLOCATIONS. 615 Fig. 134. Dislocation of the sternal end of the clavicle forward. The signs and symptoms con.sist of a subcutaneous tumor, produc- ing a prominence upon the front of the manubrium ; the aljrujtt ending of the chivicle ; the shortening between the slioulder and the mesial line of the sternum as compared ■with the opposite side ; the inclination of the head to the affected side, owing to the fact that the sterno-cleido-mastoid muscle is made tense by the protrusion of the clavicle against it ; and severe pain, increased bv any movement. The treatment consists in dniwing back simultaneously both shoulders by placing the knee in the interscapular space, and then having the end pushed into its proper place. A firm compress should be immediately applied over the site of the dislocation and held in tiifil by adhesive plaster and bandages. If the dishicated cud lias a tendency to slip out, and thus to cause the deformity to reap- pear, and if all the circumstances are favorable, the tlislocated end can be fastened by a metallic suture. Dislocation of the clariele backward occurs in consequence of a kick from a horse or a fill npt)n the shoulder. The dislocation may be a pathological one, secondary to lateral curvature of the spine. The dis- located end may be thi-ust backward and slightly upward, just above its natural jjosition, or it may be pushed downward just behind the sternum, beneath the articulating facet, near the origins of the sterno-hyoid and sterno-mastoid muscles. The signs and symptoms consist of pain, k)ss of function of the affected arm, turning of the head toward tiie dislocated side, approxima- tion of the shoulder to the mesial line of the sternum, a fossa at the articular facet, dyspnoea from pressure on the trachea, or dysphagia from compression of the oesophagus, or disturbance in both res]iiration and deglutition if the dislocated end is driven down liehind the sternum. If the end of the bone descends low enough, it may by pressure on the subclavian arterj' cause diminution or cessation of the radial pulse, or by pressure upon the brachio-cephalic vein prevent the return current in the vessel and cause passive hyperemia. Treatment. — The dislocation can usu- ally be reduced by the means already de- scril)ed, but in case the bone cannot be returned to its proper position, and diffi- culty of respiration and deglutition is present, the end of the bone should be sawed off to relieve the pres.^^ure. Thi.s procedure, however, is seldom nece.s- .sirv. Dis/ocution of the clavicle upirard occurs as a result of indirect violence, and is exceedingly rare. The signs and symptoms are tumor, formed by the projecting end just beneath the in.sertion of the sterno-cleido-mastoid muscle (Fig. 135); Fig. 135.

The signs and symptoms of dislocation of both bones forward, in whicli the olecranon is usually fractured, are — lengthenino; of the forearm ; depression in front of arm eorrespondins;- to the sigmoid notch ; great j)rominence of the condyles of the humerus ; depression behind, where the olecranon belongs, with aljsence of this process from its normal place, and its presence in the trochlear fossa on the front of the condyles of the humerus. The signs and symptoms of dislocation of both bones outward or to the radial side (Fig. 145) are — flexiqn and immobility of the forearm ; jironation of the forearm, with the head of tile radius upon the outside of the joint and rotating just beneath the skin ; and great prominence of the in- ternal condyle of the humerus. This dislocation is in- complete, since the ulna catches against the external con- dyle. The signs and symptoms of dislocation ot both bones inward or to the ulnar side consist of prominence of the external condyle, flexion of the forearm and pronation of the hand, and the presence of the olecranon jirocess npon the inner side of the joint. This dislocation is not as common as the preceding one, on account of the obliquity of the articulating surface, which is higher internally.

This is often the nio.st difficult dislocation in the body to reduce, and also, at times, the most easily reduced of all di.slocations (Fig. 152).

It", now, tlie first and hccoikI rnritilcs are considered tooetlier, it is evi- dent that tlie signs and symptoms differ only in deori'e and not in kind, since in both varieties the toe and foot are inverted, tile knee flexed and adducted, the thio;h rotated inward, with siiort- ening of linih and prominence of tlie trochanter major, and elevation of tlie ghiteo-femoral folds. If the third and fourth varieties are con- sidered tojiether, it is evident that many of the signs and symptoms differ asjaiii only in degree and not in kind, since in both varieties the toe and foot jioint downward and forward and are everted, the knee is nearly straiijht, and the trochanter major flattened. In the doirii- trard dislocation there are two inches of leiioth- ening, while in the bachirard dislocation there is half an inch of shortening. The inversion of the toe and foot in the first and second varie- ties is due to the outer band of the Y-ligament of Bigelow, since division of this causes the sign of inversion to disa]i]K'ar, as pointed out by Bigelow. In considering the treatment of dislocation of the hip the obstacles which prevent reduction must not be overlooked. They consist of the Y-lig;niient ; the capsule which girds the neck of the bone, the small rent in which pi'c- vents the free return of the Ijone into the joint ; the sciatic ncVve, which may become entangled by forming a loop around the neck of the bone; the obturator externus tendon, which becomes ten.se over the back of the neck of the bone; and, finally, the muscles, which often ciiibrace the head in a slit-like aperture. The treatment by manipulation consists in overcoming by certain movements these various obstacles to reduction. The leg is flexed upon the thigh to serve as a I'islucation into tlie obturator foramen. 632 DISLOCATIOSS. \v\v\- for tlie surgeon ; tlic tliitili is tlien flexed iipdii the pelvis to relax the Y-li<;aiiient.

In six cases reported, only two were reduced by an Fig. 16.3. la^ ■ l| ^ >^rNr— ^ "xi— ^ ;^^3^5r^'CF5 , /' iS^ i 'il i il-^" V \ ^^^^ i : Reduction of dislucatiun on the pubes by Sir A.

In dislocation by rotation the leg is twisted upon its own vertical axis either inward or outward, the latter variety being the more frequent. The appearance is so characteristic that a description of the signs and symptoms is unnecessary. Fig. 167. Subluxation of the head of the tibia forward. Complete dislocation of head of the tibia backward. The treatment of dislocation of the knee-joint e(insists of extension of the leg, with coiinter-e.xtension from the thigh and pressure of the head of the tibia inward, outward, Ijackward, or forward, according to 634 DISLOCATIONS. the special variety. Care siiouid be taken to avoid hyper-extension of tile leg, as the popliteal vessels might he injured. In the dislocation by rotation the rethiction is easily effected by twisting the leg in tiie long a.xis of the limb in the opposite direction, while extension at the same time is nutintaini'd. jVfter reduction of the tlislocation the entire limb should be placed in a plaster-of-Paris bandage, and retained in an innnovable position for several weeks. Passive motion should be employed after the removal of the splint, and no active movement allowed for another week after the discontinuance of the splint. Compoinul dift/ocafion of the knee-joint is a most serious injury, owing to the large size and complicated structure of tiie joint. If the wound is small and nothing foreign lias entered tiie joint, the aperture can be her- metically sealed with styptic collodion painted over a thin iilm of absorb- ent cotton. The wound, including the joint, should be dressed ascptically and the limb placed in a plaster-of-Paris splint. If the wound is barely large enough to admit the finger, the joint should be thoroughly irrigated with warm bichloride-of-mercury solutic^n of the strength of 1 : 10,000, prepared with distilled water. A counter- and dependent opening should be made in order to drain freely the cavity of the joint, and after dress- ing the knee aseptically the conventional retentive apparatus of plaster of Paris should be applied. If the wound is larger than is sufficient to admit the finger antl the soft parts are lacerated, a jjrimary resection should be performed, provided the patient is young, ^itli healthy viscera and organs, and no large vessels or nerves are injured. Under these same conditions primary amputation is indicated when the patient is old, feeble, or affected with visceral disease, or when the main vessels and nerves are injured. Conservative surgery can accomplish nuich in these days in cases where a few years ago amputation was tlie only hope for tiie patient's life. In severe cases thrombus of the popliteal vessels has been observed, and gangrene resulted, requiring immediate amputation. Dislocation of the semilunar cartilages involves a sub- luxation of the cartilage from its normal position, Avhich may occur in consequence of a sudden twist or wrench in elderly people, or the dislocation may occur as a result of chronic disease of the joint. In this injury there is sudden loss of the joint-function, attended by excruciating pain, which is often so intense as to cause the patient to faint and to fall to the ground. There are no immediate character- istic signs, as far as the joint is concerned, l)ut tlie joint soon becomes swollen from effusion and the inflaunnatory reaction is very great. This dislocation nuist not i>e mistaken for a loose cartilage in tlie joint, which is a chronic condition often recurring with some of the signs of disloca- tion, only of not so severe a character. The treatment consists in returning the cartilage to its normal posi- tion while the patient is under tiie influence of an ansesthetic. The jxitient should be jilaced u])on his iiai-k, tlie surgeon's left arm should be passed under the popliteal space, and the leg seized and flexed by an assistant. This manipulation under anaesthesia separates the joint-sur- faces, and the cartilage can be now pushed back into its normal place by the surgeon's right hand. After reduction the ice-cap should be placed SPECIAL DISLOCATIONS. 635 Fig. 168. Apparatus employed to limit motion in disloca- tion of the semilunar cartilages. Fig. 169. over the joint for twciity-four lioiirs, and then a plaster-of-Paris splint applied over a thick layer of absorbent cotton to produce unitbrni and equable pressure. If the disloca- tion has a tendency to recur, the surgeon can cut down upon the loosened and displaced cartilage and suture it to the bone, or even excise it. This operation must be undertaken with every antiseptic precaution. In cases where no operation seems advisable some ap- paratus should be made to limit the amount of movement in the joint (Fig. 168). Dislocation of the patella occasionally occurs, and forms only about 1 per cent, of all dislocations. The injury may be the re- sult of mechanical violence from a blow or a fall upon the side of the bone, especially when the knee is slightly flexed, or the dislocation may occur from muscular ai'tion, or the condition may be congenital. The varieties are outward, inward, vertical, and upward. Any of these varieties may be complete or incomplete. The out- ward variety (Fig. 169) is the most common, though the natural plane of the trochlear surface Mould seem to favor the inward variety. The signs and symptoms of outward dislocation of the patella are flatness of tiie knee, tense condition of the quadriceps extensor muscle, inability to flex the knee- joint, and the patella resting upon the external condyle. In the imoard variety the signs and symptoms are similar to the above, except that the signs are found upon the opposite side of the condyle. This variety is always the result of mechanical violence. The rertical or rotary variety has been observed upon a few occasions, and is caused by a sharp blow U])on the side of the patella mIicii tiic knee is in the semi-flexed position. The upward variety occurs only with rujiture of the ligamentum patelhe. The accident is accompanied by considerable .synovitis. The upward dislncation occurs when an attempt is made to prevent one's self from falling backward, or it may follow as a result of falling ujjon a liroken ])iece of glass or by a sabre cut. The treatment of dislocation of the patella in the outward, inward, and vertical varieties consists in elevating the entire limb, so as to relax the quadriceps extensor nuiscle, which should be pushed toward the patella while tliC limb is tlius hyper-extended. The bone itself is now pushed by means of digital pressure into its proper position. Hooks have been inserted under the skin to make outward traction, but their use is attended with more or less danger. In the upward variety the ligamentum patelhe nuist be sutured to its original point of attachment to the tibia at the place from wliich the tendon lias l)een torn. This operation mu.st be performed with great care and with every antiseptic Andrews's case of dislocation of 636 DISLOCATIOXS. preciiiition, since the close proximity to tiie knee-joint niiikes the opera- tion one of more or k'ss gravity. The knee shoiikl he placed, aiter reduction, in a plaster-(ji'-Paris splint. ^Vf'ter several weeks the dressing can he removed and an elastic knee-cap applied over the joint, in order to maintain tlu' jiatella in its proper position, and also to att'ord greater security to the patient. In the congenital variety a knee-cap should be worn, which has a tendency to prevent the bone from slij>ping too far out of its place. Di.SLOf'ATiox OP THE FIBULA occurs as a result of mechanical violence, muscular action, or disease or arrest of growtii of the bone, or some attV'ction of an adjacent joint, or even by lengthening of the tibia or tibula l)y hypernntrition. There are two varieties — one in the upper part, at the superior tibio- fibular articulation, and the other in the lower part, at the inferior fibio- fibular articulation. In the first variety the dislocation may be either forward, backward, or upward. This variety is caused by a blow upon the head of the fibula, or by a sudden contraction of the Inceps muscle, or by shortening of the tibia in consecpience of fracture of tlie bone. Dislocation in the lower end of the fibula may be also either /or- ward or backward. In this variety a fracture is often associated with the dislocation. The signs and symptoms are to(j apparent to require any special description. The treatment consists in pushing the dislocated end back into its place after first relaxing, by flexion, the muscles the contraction of which would interfere with the rcducti(in. If this fails, the knee can be extended with the foot strongly flexed. When the bone is in its proper place a compress should be applied to the dislocated end, and the entire limb placed in a plaster-of-Paris bandage for several weeks. Dislocation of the ankle-.ioixt forms about 3 per cent, of all dislocations. The injury is usually caused by a fill ujjon the foot, or by a force expended upon the part of the ankle opposite to the disloca- tion. A fracture is very often associated with this dislocation. The varieties are outward, inward, forward, backward, and upirard. The fibula is usually fractured in the outward, forward, and backward varieties, and the tibia in the inward variety. In the outward dislocation (Fig. 170) the foot is twisted and its plantar surface is turned toward the filiula, the internal lateral ligament is usually torn, and the inner malleolus projects just beneath the skin. This variety is often mistaken for Pott's fracture. In the inward dislocation the internal niallef)lus is usually fractured ; the other side of the foot rests upon the ground, and tlu' inner side of the foot is turned upward. In the forward variety the foot is very much lengthened and the tibia rests upon the upper and posterior part of the os calcis. This form of dislocation is exceedingly rare. In the backward variety the foot is very much shortened, the internal lateral ligament is torn, the external lateral ligament and the fibula are broken, the heel is very prominent, the toes point down, and the end of the tibia is thl•o^^•n upon the scaphoid and the internal cuneiform bone. In the upward variety the tarsal bones are forced up between the SPECIAL DISLOCATIONS. 637 tihia and fibula, and the ankle-joint is very much increased in its lateral diameter, while the vertical measurement of the toot is much less than normal. The treatment consists in flexing the leg upon the thigh to relax the tendo Achillis, and in making forcible but gradual traction upon Fig. 170. Dislocation of tlio ankle-joint outward. the foot in the opposite direction to that from wliich the foot was thrust at the time of the accident. Division of the tendo Achillis may be performed with a view to facilitate the reduction. The foot should be ])]aced at once in a plaster-of-Paris splint, or in lateral wooden .splints witii holes in the si(ic to correspond to the salient points formed by the two malleoli. In simple dislocation of the ankle the reduction is easily accomplished, and if the joint is given sufficient pliysiological rest the injury will repair witluiut any difficulty. Compound dislocation of the ankle-joint was formerly considered a mo.st serious injury. Even in tliese days, at a time when the technitpie of aseptic surgery is nearly perfect, the management of these cases is often attended with unsatisfactory results. The mortality in past years was very great, and blood-poisoning was the usual cause of death. At the present day this cause of death has been practically removed, but 638 DISLOCATIONS. tlie question as to the adoption of tiie best means of restoring the perfect function of the ankle-joint is a most inij)ortant one. Tiiere are certain Procrustean rules the strict observance of whicth has given to the writer most satisfactory results — first, as regards the life of the patient, and second, as reganls the complete function of the joint. These rules are immediate ase])sis of the entire limb ; thorough irriga- tion of, and free di-ainage entirely through and across, the ankle-joint ; the securing of perfect inuuol)ility with plaster of Paris; removal of the drainage-tube on the third day, with final irrigation and closure of the drainage o|)euiiigs ; the employment of gentle passive movements and massage at the end of the tiiird week ; and the free use of the joint with- out crut(!iies or cane at the end of the sixth week. Any result other than one attended with no constitutional disturb- ance and with complete restoration of the joint may be called unsatis- factory. The adoption of merely one or several of these rules will not yield a good result. Their adoption from the l)eginning to the end in the order mentioned is necessary to secure a satisfac-tory result. Perfect asepsis at the stiirt will not yield brilliant results unless faithful and conscientious attention is paid to the subsequent details. Each rule must be observed in proper sequence in order to obtain at the end of the treatment an ideal result. Immediate. Axcpxix of the Entire Limb. — Too much importance can- not be jilaeed upon this first rule. Tiie extremity should immediately be thoi'ougidy washed with an abundance of soap and warm water, protect- ing at the same time with iodoform gauze the ojiening into the joint durino; this ablution. The entire limb should be clcanlv shaved with a razor and again washed, after which the parts should be freely irrigated with a 1 : 500 solution of bichloride of mercury. A saturated solution of iodoform in ether should be poured over all the limb. The part should now be protected with towels wrung out in a bichloride solution, 1 : 2000. Having removed the wet towels ])laced under the leg during the aseptic cleansing of the limb, and having substituted clean bichloride towels, attention is next directed to the joint itself. Thorough Irrif/ation of the Joint. — An irrigator suspended a few feet above and filled with a hot 1 : 5000 bicidoride solution should now be used. The nozzle of the syringe should be introduced into the joint and all the blood-clots washed out, together with debris that may have entered the joint. A strong director should be passed through the joint until its blunt end is felt at a point opposite, and then it should be cut down upon and the wound made large enough to admit a large-sized drainage-tube. Surgeons have been accustomed to drain the joint upon one side, and introduce the tube at the opening made at the site of the injury. This is inadequate and insufficient. A pocket upon the opposite side of the joint is formed in which l)lood-serum, lymph, and synovia collect, and thus a nidus is formed for infection. Unless the joint is thoroughly irrigated in all its parts there is danger of abscess. If a study of com- pound dislocation of the ankle-joint is made, the interesting fact is observed that abscesses are subsequently formed upon the side of the joint directly opposite to the original opening. The time of formation of these abscesses, and their situation and character, point to the fact that SPECIAL DISLOCATIONS. 639 their ilevclopmcnt Is due to sepsis originating within the joint. The curious clinical fact tliat some time after the original injury to tiie joint an abscess forms upon the opp(.isite side, and wiiere the tissues are all sound and uninjured, suggests at once that the abscess is due to sepsis and caused by the ix^tcntion of septic material in the pocket of the joint distant from the original ^V()und. By free and perfect tlrainage, by anti- septic irrig-ation at tlie time of the first dressing, and by providing a free outlet tipon the healthy side of the joint, we may make sure that no retention of blood or lymph or synovia can take place, and ^\•llerever such perfect drainage is established the abscess is prevented. The abscess that forms under these circumstances is prolific of evil. It sets up free suppuration in the joint, and this is followed by necrosis, and then resec- tion or amputation nuist be performed as a dernier ressort to save the patient's life. The next rule to adopt in the management of these cases is the imme- diate fixation by plaster of Paris. Perfect immobility is essential, and this can be best secured by the employment of the plaster-of-Paris band- age. The wound having been covered by iodoform gauze, and jiieccs of wet bichloride gauze having been jilaced loosely over the wound and upon the foot and leg, a wet antiseptic bandage should be ajiplied to keep the loose dressing in place. Over this a coml)incd dressing or layers of purified cotton should be rolled, and a bandage to keep the dressing in place. A piece of sheet iron about one inch in breadth, and lient at the heel so as to extend from the toe down the plantar sur- face of the foot over the heel and up on the posterior surface of the leg, reaching above the knee-joint, should be adjusted. A corresponding strip of sheet iron bent to fit the dorsum of the foot, the front of the ankle, and the anterior surface of the leg should next be ajiplied. Two short lateral splints of the same material should be placed on either side. The plaster-of Paris bandage can now be rolled over the splints, and a light ])laster l)andage applied, which now possesses great strength on account of the splints, but which is not heavy or cumbersome. At the first dressing a fenestrum can be cut over the \\ounds in order to with- draw the drainage-tube. The leg can be suspended by a Salter swing, which will enable the patient to move about in all directions in bed during the repair of the wound. If there is any difficulty in placing the fi)(>t and limb in proper position, the tcndo Achillis can be divided, aTid thus physiological rest is at once enforced. Still another rule refers to the time of removal of the drainage-tube. If the wound is small and there has been little laceration, the third day is the most appropriate time for the entire removal of the drainage-tube. If, however, there is an excess of discharge from it, the tube can be allowed to remain until the following day. At this dressing on the third day, if it is thought lyest, for the reasons given, not to remove the tube, then it should be irrig-ated, the iiozzle of the syringe being introduced into one end of the tube, and a weak bichloride solution passed through it and through the joint, and the drainage made once more free. It sometimes happens that after the joint has lieen irrigated the tube can be divided into two parts and a short end inserted into each of the bilateral wounds, and these left in until the following day. If the tubes remain longer than three or four days, they excite irritation in the joint 640 DISL CA TIONS. and may set \\\> suppuration. Ajjain, the rnhlter tulles beeome softened in tiiree days, and are likely to tear aj)art, owinji' to the tension prodneed l)y withdrawintr them throni;h tissnes to which they have become afiiiln- tinated by inflammatory adhesion. Finally, after three days the tiilx's, having accomplished the object for which they were employed, should be removed, because they are not intended to drain pus, but to carry off the products of acute intlanunation arising from the traumatism to the joint. The rule which relates to passive movements and massage at the end of the third week is an important one to observe. Any movement of the joint prior to this date is attended with danger. The parts are not ready for passive motion before three weeks, and an attemj)t to move the joint prior to that time will excite a new inflammation which may lead to supjniration. If the joint is not moved at this time, the adhesions become firm, and ankylosis is certain to follow, and consequently the function of the joint is destroyed. Shampooing and gentle friction are also valuable adjuvants at this period in the history of the injury. It is to be especially noted that the movement allowed to the joint is not active, but passive, and the former should not be permitted until six weeks from the date of the accident. The rule that Sir James Paget has given is here especially applicable. He taught that an acutely- inflamed joint with heat and tenderness in it should be kept physiologi- cally at rest, and that a joint that was stiff and partially ankylosed, but was free from all inflammatory action, should be treated by passive motion and massage. The last rule refers to the time when the patient should begin active movement in the joint. Active motion in the joint is necessary at this period to excite the secretion of synovia, to release the tendons from any adhesions due to a thecal inflammation, to disintegrate fibrous adhesions, to restore the natural motion in the joint, and to absorb any of the products of inflammation or of collateral ledema and ecchymoses in the surrounding soft structures. It sometimes happens that at this stage swelling occurs in the leg or in the foot from the removal of the plaster bandage. This is, however, only temporary, and will soon disappear njion the patient walking about for a few days. If active motion is allo\\'ed earlier than the sixth week, there is danger of exciting new and suppurative inflam- mation in the joint, and a joint that gave every prospect of becoming perfect in function at the end of the second or third, or even the fourth, week may become totally destroyed by a too early employment of motion at a time when absolute rest is imperatively demanded. No hard-and-fast rule can be made as to the amount of movement that the patient should be allowed to make. The best guide is the feel- ings of the patient. Too much exercise is as harmful as too little, and exercise attended with ]xiin and fatigue is as injurious as movement of the joint a week after the injury. The patient should be advised to move the joint l)ut little at first, and by increasing the amount of move- ment daily perfect restoration of the joint can be secured. Dislocation of the astragalus occurs as a result of falls from a height or of a sudden wrench or twist of the foot. In these injuries the ligaments are torn from their attachment, and the bone, being free, is thrust out of its position by the tibia, while the foot is strongly flexed, SPECIAL DISLOCATIONS. 641 extended, or inverted. The bone is dislocated from its relative position between the os calcis and the tibia and fibula. This injury must not be mistaken for dislocation of the ankle-joint, a description of which has alreadv lieen given. In dislocation (if the astragalus tiie bone not only is separated frtmi the malleolar arch, l)ut also from its attachments beneath to the bones of the tarsus. In dislocation of the ankle-joint the astrag- alus maintains its relative position to the bones of the tarsus. The varieties are forward, backward, outward, or inward, and by verition. In the fonrard dislocation, wiiich is tiic most frequent, the bone becomes displaced in consc(picnce of a fall or by a twist of the foot, which is at the time of the accident in tiie position of full extension. The astragalus is thus thrown forward against the astragalo-scaphoid lig-amcnt, which gives way and permits the bone to be thrust out of its socket and become lodged just beneath the skin on the dorsum of the foot. The signs and symptoms are tlic presence of the rounded head of the astragalus ujioii tlic dorsum of tiic foot, the disappearance of the normal landmarks of the joint, the complete loss of function, the short- ening of the limb, owing to the position of the malleoli near the sole of the foot, the prominence of one malleolus and the obliteration of the other, M'ith either inversion or evcrsion of the foot. Dixlocntioii of the astrdi/a/iis Ixtcku-drd occurs as a rare injury. In this varictv the bone is forcibly driven backward and either outward or inward u]ion one or the other side of the tendo Achillis. The inferior surface of the bone lies upon the back part of the superior surface of the OS calcis. This accident occurs when the foot is in extreme flexion, the reverse of the position when a forward dislocation occurs. The injury results from a severe twist or wrench which causes rupture of the poste- rior fibres of the deltoid and external lateral ligaments, as well as of the interosseous ligament. The signs and symptoms are the presence of a bony prominence just above the heel, with the tendo Achillis stretched tightly over it upon one or the other side ; a marked depression u])on the front of the ankle-joint, witli a prominent ridge above the fossa, consisting of the anterior articulating margin of the til)ia ; complete loss of function and marked flexion of the foot and innnobility of the ankle-joint. Dislocations of the asfrar/alus outward and inicard occur with equal frequency, although either variety is seldom observed. If the disloca- tion is complete, a fracture of the corrcs]ionding malleolus occurs, and the dislocatiori is thus complicated. This act'idcnt results from some severe violence or by a fall U])on the side of the body when the foot is caught and held firndy within tiie tight grasp of some object while the person is in moti'on. The signs and symptoms of lateral dislocation are — presence of a bony prominence upon one side of the foot, with a corresponding depres- sion u])on the opposite side of the joint ; and crepitus, as a rule, since the malleolus upon the affected side is fractured. Dislocation of the astrrir/ahis bi/ version occurs from a sudden twist or wrench of the foot, and the bone may undei'go rotation upon a hori- zontal or vertical axis. During the receipt of the injury the foot is Vol. I.— tl 642 DISLOCATIONS. usually placed midway between Hcxinn mikI cxtcnsidn, and ron.«efjueiitly at a riiflit angle to the leg'. Tlu' signs and symptoms are cliicHy neiiative, since tliere are no eharacteristie ehanges which enable the surgeon to diagnosticate the pre- cise nature of the injury. The diagnosis must be established upon the sudden loss of motion in the joint, severe pain increased by movement of the foot, a rapidly-oeeurring synovitis, partial loss of the normal con- tour of the joint, and, tinally, the existence of a serious sudden joint affection, without any bony prominences to serve as a guide to determine the character of the injury. The treatment of dislocation of the astragalus is complex, varying somewhat according to the special variety and the extent of damage inflicted. In the incomplete form the dislocation is easily reduced. In the coni])lete form often great difficulty is met with in attempts to rectify the condition. In the forirard variety continuous traction of the foot upon the leg must be made, with the knee flexed to relax the tendo Achillis. It is usually necessary to make this manipulation with tiie patient under the influence of an auiesthetic. If by flexion, extension, traction, and manipulation the bone cannot be returned to its ]iroper place, the tendo Aciiillis and any other rigid tendon shoidd be divided. Tenotomy usually permits the reduction of the dislocation. If, now, the surgeon is still unable to return the bone to its proper jilace, an incision should be made and the obstacles to I'cduction removed if ])os- sible. If this fails, the question of a primary resection, conservatism, or amputation arises. The operation of resection depends upon the con- stitution, age, and extent of damage to soft jiarts. If the jtatient is young or in adult life, witii healthy viscera, and the astragalus is causing pressure enough to produce slougiiing of the skin, a resection should be made, since with antiseptic surgery a primary resection is far better than to wait until abscesses form and extensive caries follows, which neces- sarily leads to secondary resection or amputation. If the dislocation can be partially reduced and movement in the joint is possible, and the patient is feeble or aged, conservatism should be tiie line of treatment. It is surprising how useful a joint can l)e secured in these cases under such conditions. If the dislocation is compound, the patient aged, and the soft parts are badly damaged, Synie's amputation is indicated. After reduction of a dislocation of the astragalus a plaster-of-Paris splint should be applied and the joint kept absolutely quiet for at least six weeks. If a resection is performed, the rules already given for resections should be adopted, and if amputation is re(]uircd, the ordi- nary rules governing this operation should be observed. SubaMmriaJohl dislocation consists of a sejiaration of the astragalus from the scaphoid and os calcis. In this dislocation the connection between the astragalus and the tibia and fibula is not disturbed. The varieties are forwurd, Ixicl-irnrd, oidirard, and inwiird. If the foot is dislocated forirard, the head of the astragalus rests upon the calcanear facets ; if hacbcard, upon the dorsd surface of tiie scaphoid or cuboid bones; if outward, upon the cuboid lione ; if inward, u|)on the tuberosity of the scaphoid bone (Fig. 171). These subastragal()ile, and the leg held firmly down, while the foot hangs just over the edge of the table. If the tendons resist, they must be divided. After reduction the rules governing the management of dislocations in general should l)e strictly adliered to in every case. In coinpoxnd mihaxtraf/aloifl dislocation a primary resection offers the best chance for the recovery of the ])atient and for tlie future usefulness of the joint. If the Ijone projects and its ligamentous attachments are torn, the bone is likely to become carious, which eventually leads to a secondary resection, and the results ol)tained under these conditions are not so advantageous as those from a j)riiiiary resection under improved antiseptic methods. Dislocation of the medio-farml lioiirs: is occasionally observed. The OS caleis, scaphoid, cul)oid, and the cuneiform bones have all been dislo- cated, either alone or in conjunction with each other, and generall}' such dislocation is as.sociated witli a fracture. The signs and sjrmptoms arc tlie ]iresence of a dorsal bony promi- nence, a depression corresponding to the situation of the bone, and oblit- eration of tlic plantar arcli of the foot. The treatment consists in traction of the anterior jjart of tlie foot while the heel is held firmly, and digital pressure to push the bone into its noi'mal place. In uncomplicated cases reduction has usually been effected. In comjwnnd dislocation of the medio-tarsal bones the ex- tended bone .should be removed if the skin is badlv damaoed and the 644 DISLOCATIONS. bone is free from its ligiimt'titous attachmonts ; otlicrwise caries of these articulations is likely to folK)W and necessitate a secondary resection or amputation, the ultimate result of which is not so favorable as is that of a primary excision of the dis])laced bone under strict ase])sis. Dislocation op the Jii-yrATAiiSAL boxes may occiu- as a result of a fall from a hciirht in which the ])atient strikes upon his foot, or by a heavy weight tailing directly upon the dorsum of tiie foot, and in excep- tional cases even by muscular action. The first metatarsjil bone is more frequently dislocated than the second. The third, fourtli, and iifth are usually dislocated togethei', rather than singly. In some cases all of the metatarsal bcjues lui\e been sinudtancouslv dislocated. The signs and symptoms are too apparent to require any special description, since the character of tlu; injury is at once recognized. The treatment consists in traction of the toes while the heel is held firmly and mani])ulative pressure exercised. If this fails, the bone can be cut down u[ion and forced into its position. Asa rule, reduction is most easily acconqtlislied. In those few cases where fiihire to reduce the bone was reported the foot was fairly useful, notwithstanding the unreduced dislocation. In compound dislocation with extensive bruising of the soft parts, and with the ligaments badly torn, a primary resection of the bone is indicated, and in only very exccjitional cases would an amj)utation be performed. Dislocation of the phalanges is not often observed. The dislo- cation occurs as a result of a fiill upon the toes or liy direct violence, as in kicking some object or stubbing the toe against a stone. The great toe is more often the seat of dislocation than the others. The signs and symptoms are too apparent to need any description. The treatment consists in traction of the dislocated toe while the foot is held tirndy by an assistant. If the reduction cannot be effected in this way, some form of traction forceps, such as are ust'd in case of dislocation of the thumb, can be employed. If this manipulation fails, the bone can be cut down upon and another attempt made, and in case of repeated failure a primary excision of the phalanx should be performed, or even an amputation of the toe, especially if it is any otiier than the great toe. ANESTHESIA. By h. c. wood, :m. d., ll. d. Ik considering the subject of anaesthesia the first question wliich arises is as to the choice of tlie antestlictic, and in discussinji' tiiis it seems to me important to cull attention briefly, but emphatically, to the relations which ought to exist between clinical and experunental medicine. The value of experimental medicine to the profession is very great, but it is entirely possible to go wrong in the practice of medicine by attaching too nuich weight, or rather by attaching improper weight, to the apparent results of experiments. The ultimate ajtpeal for a final decision in thera- penties nuist always be to clinical medicine. Experiments upon the lower animals are sometimes useful as guides in making experiments upon human beings, but their chief value is to be found in the intei'pre- tation of the results reached at the bedside. So much attention has been in the past few years given to the experimental study of anaesthetics that there has been danger of undervaluing the clinical side of the suliject. In the present article it is proposed to consider first the clinical, second the experimental, evidence. In the selection of an antesthetic the question of safety is jiaramount. One anaesthetic may be more convenient than another, less disagreeable to the patient, less costly in time to the surgeon ; but the question of safety should dominate all otiiers. It should never be forgotten that at present we know of no true aniesthetic (for nitrous oxide, for reasons given hereafter, scarcely belongs to the class) whose use is unaccompanied with danger. It is true that recent, and perhaps even the older, medical literature is flecked with the assertions of various surgeons that not only have they given anajstheties many hundreds of thousands of times with- out accident, but also tliat these results have been due to their own indi- vidual skill, and that if their methods of administration were adhered to all the danger of ansesthesia would be overcome. There are few things more tiresome in medical literature than these clamorous outcries of conceit and vanity. The surgeon who claims that in his hands anaesthetics are free from danger, forgetful that death from ana?sthesia has occurred in the practice of Simpson, Symes, Gross, Agnew, Billroth, and almost the wliole of the list of the world's greatest of sur- geons, causes in us some amusement, and still more disgust. Anaesthesia produced in any way is a condition of danger, and the one great hope of safety on the part of the patient lies in the recognition of this fact by the anfesthetizer. Despite all precautions, given so many thousand anaesthe- sias there will be so many deaths from the anasthetic ; the oulv ho])e is by careful study and by careful administration to reduce the mortality 645 646 ANJESTHESIA. to tlif iniiiiinum : tlic unexpected will in all ])robability sometimes happen to the end of time. These things being so, the lirst matter to be decided is what the clin- ical records reveal as to the comparative frequency of the deaths from the various anaesthetics. Fortunately for our purpose, there have been recently published several elaborate studies of these records — studies so complete that reliance upon them is justitialjle and further examination of the original records almost a waste of time. The number of sub- stances which have been used by the surgeon to produce unconsciousness is quite large, yet three anaesthetics — nitrous oxide, ether, and chloro- form — stand out before all others so prominently that I shall first study their comparative safety and use, afterward calling attention to some of the minor anaesthetics as a sejiarate group. In viewing any subject statistically there is always danger of being misled by fallacies which are too commonly recognized to be here dwelt upon in detail. There are two ways in which these fallacies may be more or less completely avoided : first, by the selection of a comparatively small cluster of observations made by a single individual or a small group of individuals under circumstances as nearly uniform as may be ; second, by the gathering together of an immense number of statistics, made under all conceivable circumstances by all sorts of observers — a collection in which the mass is so large that there is hope that mistakes in one direc- tion may be counterbalanced by mistakes in the other. The best recent exam])le of the first method applied to anaesthesia with which I am familiar is in the table cdrnpiled from the St. Bartholomew Hos]>ital Reports by Dr. Geo. M. Gould, editor of the Medical News of Philadel- phia. From 1875 to 1890, inclusive, in the St. Bartholomew Hospital anaesthesia was produced 19,526 times by chloroform, 8491 times by ether, and 12,941 times by ether preceded by nitrous oxide. The num- ber of deaths were respectively l-'}, 3, 1, giving the mortality of chloroform as 1 in 1502, ether as 1 in 2830, and ether preceded bv nitrous oxide as 1 in 12,941. Of statistics in which it has been attempted to avoid error by mass the most recent and probably the best is the table prepared by Dr. Gould based upon that pul)lished by Julliard, who in turn used that of Compte as a foundation. In this table there are included 638,461 administrations of chloroform, with a total of 170 deaths; 300,157 administrations of ether, with a total ^A' IS deaths, giving a mortality of chloroform anaes- thesia as 1 in 3749, and ether anajsthesia as 1 in 16,675. The probable correctness of the conclusions reached by the Gould- Julliard-Compte statistics is strongly confirmed by the closeness vnth. which the results coincide with those obtained from other large statistics. Many years ago Dr. Richardson of London placed the jirobaljle number of deaths from chloroform as 1 in 3000. In a careful iliscussion of the statistics of anaesthesia Dr. H. ]\I. Lyman reached the conclusion that the proportion of chloroform deaths is 1 in 5860. In the proceedings of the German Surgical Society in Berlin, 1891, sixty-six European sur- geons reported nearly 23,000 cases of chloroformization, with 6 deaths, giving a proportion of 1 in 3776. In the report of the Lancet Commission for the clinical study of ana?s- thetics it is attempted to get at the proportionate number of deaths by STATISTICS OF DEATHS IN ANAESTHESIA. 647 ostimating the ])rohalik' total ininilKT (if an;pstliosias and tlio total num- ber of reported deaths. The difiieulty with this method is obvious: only a portion of tlie an;estlietic deaths are reported, and the estimation of the number of inhalations is nothing else than guesswork. The con- clusion reached by the eonnnission is that there liave been thirteen times as many deaths from ehlonifurm as from ether, and that the number of inhalations of ehlorofirm has been six times as great as those of ether ; which gives a mortality-rate to chloroform more than double that of ether. These results cori'espond with the statistics of the St. Barthol- omew Hospital, but are very much more favorable to chloroform than are the conclusions to be drawn from the large mass of statistics, which mass gives the proportionate mortality about as four and a half to one. I ])ersonally believe that the large statistics, overwhelming as they are in the number of cases rejiorted, represent as near as can be the true state of the case, and that the surgeon mIio administers chkiroform faces the fact that the dangers of its use are more than four times those which confront the man who administers ether. In strong contrast to the clinical results of the use of chloroform and ether is the history of nitrous-oxide inhalation. The Linicct Com- mission has collected seventeen deaths as having occurred during the auifsthetic use of the gas : several of these eases are, however, not fliirly attributable to the inhalation, but even if they all be accepted as accu- rate reports, the mortality is scarcely more than nominal. The gas is prol)ably administered to seven or eight hundred thousand people annually by lecturers, dentists, etc., some of them men of education, others men of ignorance. In other words, many millions of inhalations have been given, many of them by incompetent ])crsons, and yet less than two dozen cases of death have occurred during the decades since the first administration of the gas. Dr. Chas. M. Buchanan' is probably not far out of the wav in his conclusion that the mortalitv of nitrous-oxide inhalation is 2 ii"i 10,500,000. The startling ditfcrence between nitrons oxide and the other agents used leads nati:rally to a search for causes. The reason of the difference is that nitrous oxide lies apart from other aniesthetic agents in being an inert substance so far as the human organization is concerned. In the production of anaesthesia it acts by shutting off the oxygen from the blood, as is shown by the fact — established by Jolyet and Blanche, bv Elihu Thompson, and by my own ex]ieriments — that an animal will live in nitrogen, in hydrogen, or even in a vacuum, as long as in pure nitrous oxide ; and that, as shown by myself,- the circulatory phenomena of nitrous-oxide ansesthesia are very similar to those which are caused bv the inhalation of jiure nitrogen or by mechanical asphyxia ; that, as demonstrated by the French observers, coma is not developed until the oxygen in the blood is reduced to 3 or 4 per cent. ; that, as proven by my own experiments,' the time recpiired for the jiroduction of ana\sthesia is practically the same with nitrous oxide as with mechanical asphyxia ; and finally, as was shown in my own experiments, that the addition of 3 per cent, of oxygen doubles the time necessary for the production of ana:;sthesia, wliilst the addition of 5 ])er cent, of oxygen more than ' Medical News, vol. l.xii., 1893. ^ TItemp. Gaz., 1890. ' Denial Cosmos, 1893. ()48 ANESTHESIA. sextuples the time required, and S ptT cent, of oxyircu indefinitely post- pones the production of eonipiete ;in;estliesia, at least in tlie doii-. During the use of the true anajstlictic there is a ])oison cireulatinii' ''^ tile blood, and when an accident occurs time is recjuired for tlic removal of this poison even if no more of tiie an.estiietic be administered. In nitrous-oxide ansesthesia there is no poison in the blood, and if at any time the partial arrest of function which has been produced by shuttinsj off the sustaining oxygen becomes too complete, tiie introduction (tf oxygen into tlie l)loo(l finds the nerve-centres ready at once to res])ond to their natural stimulus. Unfortunately, tiie brevity of the action of nitrous oxide prevents its general use for the purjioses of the operating sui'geon. When, however, a tooth is to be drawn, an abscess to be opened, or other surgical jjrocedure involving but a moment of time gone through, nitrous oxide is the safest and best of known auiesthetics. The second sulj-(|UCstion whieli presents itself for studv in as to the method in which aiuesthetics jn'oduce death ; and here, again, tlie pro- fession is under great obligation to the Lancet Commission for the extraordinary labor with which it has searched out clinical records. It has analyzed and tabulated the reports of 384 deaths during clilor- oformization, and has shown that out of this number in 227 cases the pulse fiiiled entirely before the cessation of respiration ; that 77 times cardiac and respiratory action ceased simultaneously ; and that only in 80 cases did respiration stop before tiie heart. Whatever the results of experimentation with anesthetics ujxjii the lower animals may be, it seems to me absurd for any one to claim that in man chloroform does not frequently produce death by an action ujion the heart. In numerous cases of chloroformization tiie action of the heart has been tested not only Iiy feeling tlic pulse, Init also bv auscul- tation — tested, too, witii a full knowledge on the part of the observer that leaders of the profession have declared that chloroform never kills by its action upon the heart ; and yet in nearly four cases out of five it has been noted that the death came through the heart. If clinical observations upon the simplest questions be of any value whatever, the conclusion must be tluit in the large majority of cases cliloroform death has been due to cardiac arrest. It must lie remembered that the average intelligence and skill of the surgical observers who have recorded fatal accidents from ansesthesia is simply the general average intelligence and skill of the surgical profession ; and if these gentlemen are not to be trusted to observe such jiatent phenomena as indicate a cessation of cir- culation or of respiration, to whom are we to look for such data? All observers, clinical and experimental, are in accord in acknowledg- ing that when chloroform paralyzes the respiration it does so by a direct action upon the respiratory centre ; the matter still requiring careful dis- cussion is as to the way of the syncopal deaths. When chloroform is given to the lower animals there is always after the first half minute of tlie inhalation a progressive lowering of the arterial jiressure. Uj) to this point tiiere seems to be no discordancy, and in the controversy which has raged for the last few years on the subject Ave get one firm, indisputable point — namely, that ether is a atiiimlant and chloroform a depressant to the circulation. For many years all observers have agreed that cliloroform directly lowers the arte- ANESTHESIA. 649 rial pi'essure, but great has been and still is the dispute as to the imme- diate mechanism of the tall which the drug- ])roduccs. Docs the pressure come down through the widening of the blood-])aths by a centric or vasomotor ]xiralysis, or is tlie fail in jxirt or altogx^ther due to an action upon the heart '.' In other words, is chloroform a vasomotor depressant simply, or is it also a cardiac depressant? Sausom and Harley state that during chloroformization a spasm of the small vessels can be readily seen to occur in the M'eb of the frog. Not until the tliird stage is reached, according to these authors, do the vessels relax into dilatation. If these observations be correct, chloro- form tirst stinndates and afterward depresses the vasomotor centres. In accordance with this are the experiments of Gaskell and Shore,' who find that the local application of chloroform to the medulla or its injec- tion into the cerebral artery produces an immediate rise of blood-pres- sure, usually accompanit'd l)y a slowing of the heart, this rise being fol- lowed by a fall of pressure so soon as the chloroform is able to diffuse itself over tlie circulation. In a further very ingenious series of experi- ments, Gaskell and Shore connected the carotid artei'ies and jugular vein of an animal (A) with the similar vessels of the second animal (B), so that the l)rain of A was fed exclusively with lilood from B. It is plain that chloroform given to B would reach the brain of A, but woidd not reach tiic heart of A. Under these circumstances it Mas found that chloroform administered to B produced rise of pressure in A. In a second series of experiments the blood-vessels of A were so connected with those of B that when chloroform was administered to B it reached the lu'art of A and all other portions of the body except the brain. AMien this was the case, chloroform given to B produced an innnediate fall of arterial pressure in A, without any previous rise. In other words, when chloroform reached the vasomotor centres, and not the heart, it caused rise of arterial pressure ; when it reached the heart, and not the vasomotor centres, it caused fall of pressure. The only experiments with which I am aecpiainted to which any weight should be attached as indicating that chloroform primarily para- lyzes the vasomotor centres are those published as long ago as 1S74 liy H. P. Bowditch and ('. S. Minot." In tiiese experiments, which were made upon curarized animals, " irritation of the sajihena nerve caused a much less marked rise of blood-tension than when the ansesthetic was not used. Sometimes there was absolutely no rise of tension to be observed, while at other times the rise was from one-third to one-half that jiroduced by the same irritation on an animal not subjected to the action of chloroform." Further, compression of the carotid in the cldoro- formed aniiuai did not cause the customary spasm and rise of arterial pressure. It must be remembered thi-t these experiments of Bowditch and ]\Iinot were made at a time when the importance of the suliject had not been fully realized ; that on the carotid lint a single experiment was made; and that there was frequently in the ex])eriments of Bowditch and Minot a great rise of pressure following irritation of the sensitive nerve, though the rise was not as great as in the normal dog. There seems to be no doubt that late in chloroform-poisoning there is vasV)- ' British Med. Journ., vol. i., 1S93. ^ Boston Med. and Surg. Jnurn., 1874.

The results, therefore, of J5owditch and Minot are not in any way |)roof of the incorrectness of the theory of Gaskell and Shore, and the drift (»f the present evidence is to show that chloroform in the earliest stayes of its (tction stimulates rather than depresses the vasomotor centres. On the heart itself chloroform undoubtedly exerts a steady, power- ful depressing influence. Injected into the jugular vein (see also MacWilliani's experiments), it instantly arrests the iieart's action and destroys its muscular irritability. Even the vapor of chloi'oforni, when locally applied to the exposed heart, paralyzes it.' When artificial res- piration is maintained the effect of chloroform upon the heart is very apparent.^ By a very ingenious series of experiments Dr. MacAYilliam * has [)roven that very early in chloroform anaesthesia there is a mai-ked diminution of the force of the auricular and the ventricular beats, acconi- })anied with dilatation of the cardiac chambers, due to the direct influ- ence of the chloroform. Again, as pointed out in the paper of Gaskell and Shore, even the tracings of the Hyderabad Commission show that from the very beginning of chloroformization the excursions of the heart-beat, as portrayed by the Fick manometer, get smaller and smaller in the most typical manner. Indeed, as Gaskell and Shore .say, " every one Would agree with the commission that tluy (tlie ])ulse-waves) are of the t)pical kind which would he j)roduced if direct \\eakening of the heart were the cause of the fall of blood-pressure in chloroform admin- istration." Putting all the evidence together, it seems to me to have been com- pletely demonstrated by jihysiologists — first, that chloroform is a direct depressant and p(irali/zant to the heart-inusclc or its contained r/an(/lia ; second, that the early fall of blood-pressure which occurs in chloroform- ization is in great part, if not altogether, due to this direct depression of the heart. This conclusion having been reached, attention is next naturally directed toward a study of the action of ether upon the circulation. It is firndy established by the coinciding results of very many experiments performed by various observers that during etherization there is usually a pronounced rise in the arterial pressure, which is com- monly maintained even through a prolonged narcosis, and may continue after manifest failure of respiration. Sooner or later, if the inhalation be continued, the rise of arterial jiressurc is followed by a fall, which may progressively increase until the manometrical needle reaches almost zei'o. There have been very few careful studies of the details of the action of ether ujion the circulation, but such facts as we have go to show that the primary influence of the drug is to stimulate both vaso- motor centres and heart, and that during the stage of low pressure there is depression of the vasomotor centres and also of the heart.

Tlio cardiac action of chloroform is evidently one cause of the greater fatality of ciilomforniization, hut it is not the only reason why chloro- form kills so much mcjrc frecjncntly tlian docs ether. In my experi- ments upon the lower animals I have noted that chloroform lets go its hold much less readily than does ether. This, I had always supposed, was simply due to the greater volatility of ether, but a recent very interesting research by Mr. Julius Pohl seems to show that chloroform has a primary attachment, so to speak, for the brain — /. e. a temlcncy to aecunuilation in the brain-tissues. Mr. Pohl found on chemical examina- tion tiiat there was much more chloroform present in the brain-tissues than in the blood passing to the brain — a fact to be explained only as a result of storing up in the brain. It may well be that one cause of the persistency of the action of chloroform upon tiie nerve-centres is due to this tendency to escape from tlie blood-vessels into the nerve-tissues. Nevertheless, the comparative volatility of the two ansesthetics and the comparative diffusibility of their vajjors appear to be distinct elements in the eomparati\'e danger of their use. There is very great reason for lielieving that chloroform is less Ictiial in hot climates than in colder I'egions. The British surgeons of India aver with one voice that they can administer it without evil effect. Tlie aiisesthetizers of the exti'eme southern or Gulf tier of American States are almost equally urgent in claiming safety for the use of chloroform, whilst on the continent of South America it is solely employed, again with alleged freedom from ill effect. The only explanation of these facts which seems to me ])lau- sible is that at high temperatures cidoroform va])or diffuses very rajiidly, and consequently escapes from the blood and from tlie lungs witii extra- ordinary rai^idity. So far as concerns what may be considered the major antesthetics, the question asked in the beginning of this essay has n(jw been answered ; the answer being — first, that nitrous oxide is the safest and best of the amesthetics when the ])urposes of the anaesthesia admit of its use — that is, when the anaesthesia needs only to be of sliort duration ; second, that both clinical and experimental evidence agree in showing that ether is much safer than chloroform, and, as safety is under ordinary circumstances the one quality that the surgeon should consult in the choice of an anaesthetic, no surgeon is justified in emploving chloroform unless it be under certain peculiar circumstances and for certain definite reasons or purposes. Having arrived thus far, the next (juestion naturally is, ^^'hat arc the circumstances which justify the use of chloroform? Before, however, discussing this it seems but right to consider the possibility of substituting for chlorotbrm and ether some other anaesthetic. This leads, in turn, to the study of \\liat may be termed the minor aiurx- thriicfi. Of the numerous substances which have been more or less clamor- ously put forward as valuable anaesthetics, but few require notice here. Bichloride of methylene was originally highly recommended by Dr. B. W. Richardson in 18G7, and ga\-e rise to a considerable controversy. In 1883, j\IM. Kegnauld and A'illejeau obtained directly, through agents accreawrence Turnbull in the United States. Its influence is usually manifested a few seconds after the begin- ning of an inhalation, and lasts from one and a half to three minutes after the removal of the drug irom the mouth. A peculiarity that has been rioted by several observers is a tendency for sensibility to be lost before consciousness is completely destroyed, and Professor Montgomery has especiallv noted that during ]>arturition it will do away with most of the suflering without arresting the ])ains or producing complete luicon- sciousness. The narcosis is only in rare instances accompanied by com- plete relaxation of the muscles ; indeed, it appears to be common for the 654 ANAESTHESIA. general niuseiilar tonus to be greatly increased. According to Professor flolin H. Brinton, muscular rigidity, local spasms, and even gcn(>ral tetanus with opisthotonos, occur so frequently as seriously to interfere with the eni])l<)yment of the drug as an antesthetic, especially as this condition of muscular excitement, when it develops during a sui'gical operation, is attended liy great increase of hemorrhage.' During narco- sis the corneal and pupillary reflexes are usually preserved, and the eyes are sometimes wide open and crossed from contractions of their muscles." Tlie physiological action of ethyl bromide has been studied bv Schneider, by Abonyi, by Thornton and INIaxwell,' and by myself. Schneider states that the arterial ])rcssure does not fall until very late in the bromide narcosis, and that death takes place always through arrest of the resjiiration. In these statements he is in accord with results obtained by Abonyi,^ who was not able to detect any alteration in the beat of the exposed heart of the frog in which narcosis was pro- duced. On the other hand, the experiments of Thornton and Maxwell are in agreement with my own, in showing that the arterial pressure falls early and increases steadily with a persistent inhalation. In my own experiments ethyl bromide seemed to act on the circulation simi- larly to chloroform, although less powerfully. It is possible that the ditterence of result ol)tained by physiologists has depended ujwn the ethyl bromide being impure. In the eighth edition of my Treafi'^e on Thrrapcutirx it was stated that clinical results would jirobably show that ethyl bromide is a very dangerous ansesthetie, at the time of issue of the work there being thi-ee deaths reported as occurring in a very limited number of administrations.^ To these cases must be added the death rejiorted by Dr. A. Gleieh,'' also that recorded by Dr. Reich. On the other hand. Dr. Gllles claims ^ that there were given in Germany during three years twenty thousand administrations without a single fatal result, and that there is no fatal result on record in which it has been proven that a chemically-pure bromide has been administered. This statement is, however, at present not correct. 16 cases of death from the ethyl bromide have been collected by Dr. Reich,' and of these in 5 the bromide is asserted to have been pure. It is remarkable that out of the 7 cases in which any information as to the time of death is given, in only 2 did death take place during the narcosis ; in the other 5 cases it occurred from one to three days after. In Dr. Reich's case ' the inhalation of the bromide was followed by immediate and continuous vomiting, with development of symptoms similar to those of acute phosphorus-poisoning, ending in death on the seventh day. At the auto])sy the liver and kidneys were found in active fatty degeneration. After the inhalation it was remembei'ed that the bromide used had a faint yellow color, and it may possibly be, therefore, that the fatal result was produced by some decomposition-product.

CIRCUMSTANCES MODIFYING THE CHOICE OF ANAESTHETIC. 655 present year Koclilcr reported a case' in wliieh the antesthetic was given in small quantities with a mask, and in whieh, after a very transient and mild stage of excitement, the heart's aetion suddenly ceased and could not be restored, although the breathing is said to have continued for a long time. At the autojj.sy the muscular structure of the heart was found in a condition of extreme fatty degeneration. Our present clinical experience certainly indicates that the use of ethyl bromide is not devoid of dangei', but there seems to be no sufficient reason for believing that with an absolutely pure article the danger is greater than with chloroform. The brevity of the narcosis and the great muscular excitement which the bromide is apt to provoke stand greatly in the way of its general use as an auiesthetic, though they especially fit it for employment on certain occasions. It seems probable, also, that it will be found to be a successful ]>raetice to give the ethyl bromide at the beginning of an anaesthesia which is to be maintained by the use of ether. There are certain persons, especially alcoholics, who greatly resist ethyl bromide, and various surgeons strenuously assert that under these circumstances no attempt should be made to force anaesthesia by this agent, but that chloroform or ether should at once be substituted. The best method of administering ethyl bromide appears to be to place about two drachms in an Allis inhaler or upon the cone-shaped napkin. Mixed An.esthetics. — Various mixtures of chloroform and ether or alcohol, chloroform, and ether (the latter the famous A. C. E. mix- ture) have been employed by surgeons with results \\hich have been on the whole unsatisfactory. These unsatisfactory results are probably, at least in part, dejjendent upon the different volatility of the different agents, making it impossible to know exactly what va])ors are contained in the air breathed by the patient. All these mixtures are, in my opinion, more dangerous than the individual drugs of which they are composed, and their use should be eschewed. The method of producing antesthesia with one agent and continuing it with another is entirely different from that which uses throughout a mixture of the two agents, and at present writing there seems to be reason to commend this form of mixed anaesthesia. Thus, it is probable that many of the difficulties Avhich attend the use of ether can be overcome by putting in the inhaler or on the sjionge ethyl bromide and then ether, the j)atient ])assing insensil)ly from the bromide narcosis into that of ether. In England it seems to be a not rare practice to commence antesthetization with nitrous oxide and to continue it with the use of ether, and, if the statis- tics given by Dr. George Gould are correct, this method of antesthetiza- tion would seem to be the safest known, for in 12,941 anaesthesias so produced in the clinic of St. Bartholomew's Hospital there has been 1 death. Certainly 'by the primary use of nitrous oxide the feelings of the patient and the time of tiie surgeon are spared. Circumstances wbich modify the Choice of Anesthetic. In answering the inquiry as to the circumstances which should modify the choice of the ana;sthetic by the surgeon I shall first consider those ' CmtraU.f. Chh:, 2, 1894. ()")() ANJESTHESIA. iKidifying circumstances wliicli arc siiii])lcst and least doubtful, and shall arrange the matter under eiuuneratcd licads First. When ch-cumstances make it practically impossible to obtain the ))ulir- tiitidu, determining as they do the niovements of great armies and the residtsof great national U])heavals, may make it practically impossilile for tJie surgeon to have choice, antl certainly under such circumstauces it is better to use chloroform than to do without ansesthctics. Second. When the symjitoms tliemselves are of such character as to immediately threaten life, especiaiiy if they at the same time interfere with the entrance of tlie auicstiietic into tlie lungs, the use of clilnrof irm may well be justiiied. Tlius, when a tetanus spasm locks the cliest- wails it often would be folly to wait for the action of ether, and yet it must be rememljered that under just such circumstances chloroform has ajiparently destroyed life. Perhaps under this heading the use of chlorofoi-m during parturition should be alluded to. It has Ijccn stated from time to time by vari- ous writers tliat tlie excitement of labor in some way guarantees the system against the deleterious intluences of chloroform, and that it may be used with impunity. This is not correct : death has occurred from the ana;sthetic use of chloroform during parturition. Only infrequent occurrences in parturition make it necessary to use chloroform. Ether commonly acts with sufficient jiromjitness, and should tlierefore be pi'c- ferred. In a violent case of ])uei'j)cral convulsions, however, and in other critical conditions, cldorof)rm may be superior to ether. The known action of ethyl bromide gives great force to the statements of Professor Montgomery, that it is especially valuable during labor, and further trial of the agent seems to be demanded. The obstetrician, how- ever, should exert extraordinary care to see that he has a ]iure s]iecimen of the drug. Third. There are certain bodily conditions, iiardly to be sjioken of as disease, which would exert some intluence in the selection of the anaes- thetic. In his recent book Dr. Frederic W. Hewitt states that old persons whose chests have become rigid seem not to be able to resjiond sufficiently to the demand made upon them by ether, and tliat very old persons hear chlorof )rm practically well. In applying such a principle as tliis it must be remembered that it is not the years of the person, but the extent of senile changes in his tissues, which should influence the ansesthetizer. Dr. Hewitt recommends in such cases the A. C. E. mix- ture ; if such mixture be employed, it should always be freshly made at tlie time of its administration. Extreme obesity is another bodily condition in which it is affirmed that ether is often not well boriu', producing so much excitement and respiratory irritation as to forbid its use. Under these circumstances again Hewitt recommends the A. C. E. mixture, but states that there are certain cases in which chloroform is necessary in order to secure suf- ficient tranquillity of breathing. I have not had practical experience witii such patients of sufficient amount to be weighty, but my feeling is tiiat in such cases ether should be first tried, and then, if it be not well borne, chloroform substituted, ether being again employed when quiet anaesthesia has been thoroughly established. CIRCUMSTANCES MODIFYING THE CHOICE OF ANESTHETIC. 657 Fourth. Various diseases contraindicate the use of an anesthetic, and also modify the proper choice of tlic surgeon, and I sliall therefore under the present iieading consider diseases as general contraindications to auicsthetics and also as modifying the selection by the surgeon. The diseases which are generally thought to more or less positively contraindicate the use of aniesthetics are Organic Brain Disease, includ- ing Tumors; Atheromatous Conditions of the Vessels; Diseases of the Heart ; Diseases of the Linigs ; and Diseases of the Kidneys. Brain. — It appears from the recorded accidents of ansesthesia that the existence of brain tumor and other organic forms of brain disease is more often the cause of death tlian are att'cctious of tlie heart. AVhen the brain-arteries are believed to be atheromatous, although no positive signs of organic brain disease are present, aniesthesia should be induced by the surgeon with the greatest reluctance. The cause of the extreme danger in these cases is probably the ease witli which congestions are developed in a brain which is abnormal, and the loss of resisting power in the resjiiratory centres when weakened by disease. I know of no clinical data which will enable us to decide which is the safer agent, chloroform or ether, in the class of cases now under consideration. The greater power, however, of chloroform and the greater permanency of its influence would make it, a priori, probable that ether would be the less dangerous of the two. Heart xVnd Blood-vessels. — Widespread arterial atheroma should certainly give to the surgeon wlio desires aiiicsthesia much fear as to the result. The great increase of the arterial pressure wliich takes place in nitrous-oxide narcosis may very well endanger the integrity of an athero- matous vessel. In 1890 a gentleman arose from a dentist's chair in Philadelphia after an inhalation of nitrous oxide, staggered, and fell in an apojilexy. Dr. F. A. Ashford ' reports a case of a young woman who grew faint and dizzy shf)rtly after waking from nitrous oxide, passed into a condition of disturbed consciousness, and found when she came fully to iierself that her left arm was useless. It apjiears to me, there- fore, that nitrous oxide should never be administei'ed when there is marked degeneration of the vessels, and that the danger of its employ- ment woidd be especially great if there should be an aneurism with feeble walls. Ether certainly raises the blood-pressure, but the amount of increase is not nearly so great as when nitrous oxide is given. Moreover, in the majority of cases arterial degeneration is associated with either cardiac or renal disease, or very generally with both, so that the choice Ijctwecn the two auiesthetics is commonly to be dominated not by the atheroma itself, but by the coexisting disease. In atheroma with failing lieart ctlier should certainly be ))refcrred ; in atheroma with renal disease and a normal heart chloroform ivotdd proI)ably be the safer agent. Of course an apoplexy may occur at any time during an antesthesia : the late Professor D. Hayes Agnew once lost a case during etherization ; and in the London Lancet^ is reported a ease in which a chloroform inha- lation was followed by aphasia, believed to be due to rupture of tlie cere- bral vessels. Valvular disease of the heart is sometimes alleged to be a positive con- ^Amer. Jonm. Med. Sei., vol. Ivii., 1869. 2 yo] j^ jgyo Vol. I.— 42 658 ANESTHESIA. tniiiidicutloii to aiisesthctic agents. Wlicn, however, the organic disease does not prochice any absolute functional disarrangement' of" the heart, and when the heart-muscle is in a fair condition of health, ansesthesia may l)e induced, provided the circumstances of the ease are such as to justify the surgeon taking a slightly increased risk. The key to the situ- ation is not the valvular lesion, but the conchtion of the muscle ; a loud murmur usually depends, to some extent at least, for its loudness upon the character of the valvular lesion, but it is also dependent, in part, for its loudness upon the force which drives the Ijlood through the diseased orifice. A loud murmur is therefore, on the M'hole, not more strongly contraindicative of aniesthesia than is a feeble one ; indeed, as the feeble murmur is more commonly associated with feeble walls, greater care must be exercised when such murmur exists than when a loud bruit every- where forces itself upon the physician's attention. In all cases of heart disease whenever it is possible to avoid the use of an anaesthetic by the emploj'ment of cocaine or by other local device this should be done. No condition of the heart is, however, an absolute contraindication to the use of the anaesthetic ; under certain circumstances anaesthesia may be pro- duced \vhen the heart is in advanced fatty degenei'ation. It must be remembered that the shock and nerve-strain which attend a major sur- gical operation without anaesthesia would endanger the arrest of a fatty heart even to a greater degree than would anaesthesia itself, so that the question is, after all, as to the imperativeness of the proposed operation. In diseases of the heart ether is usually preferable to chloroform ; in- deed, when the heart is very feeble or the cardiac muscle is degenerated the action of chloroform upon the heart makes it a vei'v dangerous remedy. In some cardiac cases there is a widespread pulmonic engorgement, with a tendency to exudation into the lung-vessels and smaller bronchial tubes. Under such circmiistances the local irritant action of ether upon the mucous membranes is so deleterious that the surgeon is placed as it were between Scylla and Charybdis, and may in an individual case have great difficulty in deciding what is best. The A. C. E. mixture under these circuiustances may be sometimes selected with propriety. Chloroform is especially dangerous when ortiiopncea exists ; it is doubtful whether in such a case its use is ever justifiable. Respiratory Apparatus. — The existence of severe organic disease of the lungs seems to be a less serious bar to the use of ansesthetics than would be naturally expected. Of all the chronic pulmonic affections, probably emphysema, associated as it so frequently is with weakness of the right heart, causes the most solicitude to the ansesthetizer. The irritant local action of ether is an important element when the lining membrane of the tubes or air-vessels is seriously implicated ; indeed, my own opinion is very positive that in some of the deaths which have occurred in persons with diseased kidneys from oedema of the lungs directly after etherization the cause of death has been the local irritant influence of the ether. It would ajipear, also, that \\idespread organic changes in the lung sometimes so interfere with the alisorption of ether that it becomes exceedingly difficult to produce complete ansesthesia. The dictum of Hewitt, that in extreme emphysema in chronic bronchitis attended by expectoration and dyspnoea, and in advanced pulmonary CIRCUMSTANCES MODIFYING THE CHOICE OF ANESTHETIC. 659 phthisis, chloroform or some mixture containing chloroform sliould be employed, is worthy of great respect. In all cases of lung disease it is important to remember tliat the more chronic the disorder the less important is it as a contraindication to the use of an anjesthetic, and that aniesthetics are especially badly borne when there is acute or subacute pulmonary disease. Only nnder tlie most urgent circumstances should aufesthesia be attempted when in an acute pulmonary disease the symptoms are of sufficient intensity to produce even slight dyspnoea. In recent pleurisy or pleuro-pneumonia, with any embarrassment of the respiration or duskiness of the countenance, anpes- thetization is attended with very grave risk. In obstructive laryngeal disease, or Avhen contraction of the trachea either from witiiin or without, or other mechanical obstruction, jn'oduces dyspnoea, the greatest caution must be exercised in the nse of the antes- thetic. Under these circumstances the chances of ether increasing the mechanical asphyxia by irritating the larynx or trachea are very great, so tiiat chloroform is preferable to etlier ; or chloroform may be employed at first, and ether given when the reflexes have been abolished bj^ the ol)tunding of the nerve-centres. When the laryngeal obstruction is of tile nature of a spasm, and not of an organic change, the use of the an;esthetic is free from extraordinary danger ; but it must be remem- bered that fretpiently in such cases there is more or less larj-ngeal irritation, so that chloroform is preferable to ether — a conclusion which is strengthened by the necessity M'hich often exists for the prompt action of the aniesthetic. In certain cases the mechanical obstruction may be a tumor in the mouth or other lesion above the respiratory tract proper, but if the respiration be interfered with, the general ])rinciples just enunciated hold good. Obstruction is a comparatively trivial matter, but, when it is complete, requires the surgeon by the use of the mouth-gag or other procedure to see that respiration througli the moutli is unimpaired. Operations. — The choice by the surgeon of an anajsthetic is often modified by the nature of the operation. In operations on the parts about the moutii it is often difficult to maintain anaesthesia on account of the mechanical interference on the part of the surgical operator. In such cases the rule should be for the patient first to be placed tlxiroughly under the influence of ether, and, unless the operation is to be a very lengthy one, to have been in this condition for several minutes before the surgeon begins. Usually, when the tissues and blood have been thus surcharged with ether, antesthesia can be main- tained by occasional whiifs of chloroform given as opportunity is afforded during the surgical procedure. Indeed, the first anfestlietic saturation is often • sufficient to carry the patient througli the more painful portion of the surgical work. In tliis, as in otiier cases, wlien chloroform is to be administered to an etlierized patient it is essential to remember that often during etiicrization breatiiing is heavier and deeper than in the normal individual, so that it is entirely possible inadvertently to give an overdose of chloroform. Tiie frequency of the entrance of blood into the larynx in tiiese cases comes rather within tiie ken of tlie surgeon than of tlie an;csthetizer, Init it seems worth while to copy the rules of Hewitt, that unless the convenience of the operator makes it G(i() ANJESTHESTA. iinpo.ssil)lc, drainage fi-oiii tlie iiioutli s^lioiild be secured by the patient being placed in one of tliree positions : 1. Somewhat npon the side, with one cheek resting upon tiie pillow, and so that tiie face is turned slightly downward. 2. Sitting up, with the head and shoulders thrown Mell forward, the face looking toward the couch or bed. 3. Supine, with tlie head completely extended and in the mid-line. As the diseases for which the ojierations of cerebral surgery are under- taken often in themselves contraindicate the use of anesthetics, great importance attaches to tlie question of aui^sthesia in these cases. Pro- fessor Victor Horsley has claimed that the hypodermic injection of mor- jihine before the use of chloroform is in this class of operations exceed- ingly advantageous, not simply because it lessens the amount of the antes- thetic required, but also because it decreases the cerebral congestion and the consequent hemorrhage on section. This practice has had consider- able following, but its correctness seems to be open to grave doubt. As long ago as 1863, Professor Nussbaum of Munich found that when hypo- dermic injections of morphine were given during chloroformization deep sleep continued for a considerable time after the withdrawal of the chloro- form, and that the jiatient awoke without nausea or vomiting. In 18G9 the researches of Claude Bernard were published, and led to the wide- sjjread trial of the conjoint use of morphine and chloroform. A-priorl reasoning would render it probable that anresthesia woidd be more easily produced and would be more prolonged in the semi-nar- cotized patient than in the normal individual, and clinical experience has confirmed this. But in the prolongation of the anjesthesia would seem to lurk a danger. Certainly, it is but natural to suppose that an anaesthetic accident occurring in a person who is under the influ- ence not only of a volatile and easily-dissipated poison, but also of a non-volatile and comparatively permanent poison, would be far more serious than if the failure of respiration or of circulation were the out- come purely of an agent which could rapidly be removed. Several sur- geons have shown that this reasoning is not devoid of practical support, and a number of cases have been ])ublished in which very serious symp- toms, or even death, have occurred during the mixed narcotism. In one case of Hewitt's the importance of the more persistent agent was shown by the fact that artiticial respiration had to be kept up continually for four hours before any automatic breathing appeared, the fact indicating that, at least in that case, the morphine had more to do with the complete arrest of respiration than had tiie etiier. Further, in many persons the use of opium is prone to be followed by excessive nausea and distress; in such an individual the disagreeable! after-effects of the anaesthetic would certainly be aggravated. Some surgeons consider that ether should not be used in abdominal surgery on account of the frequent respiratory movements, the cough, the retching, the vomiting, etc., which sometimes attend the employ- ment of this anpesthetic, interfering with the delicate work of the sur- geon. The presence of these disturbances, however, is usually an indi- cation of improper ansesthesia. Rigidity of the abdominal nmscles, retching, and general restlessness are to be overcome by the free use of the ansesthetic. The disturbances of respiration may depend upon CIRCUMSTANCES MODIFYING THE CHOICE OF ANESTHETIC. (Kil interference with the supply of air, or perchance may be the beginning asphyxial symjrtonis due to the excessive etherization. Viok'nt and excessive vomiting after an abdominal operation is a serious thing, and certainly it is more apt to occur when ether has been used than when cidoroform has been employed. It can, ho\\"cver, be largely prevented by proper method of administration. Acute intestinal obstruction, with the general colla])se which so often accompanies it at the time when the case comes into the surgeon's hands, requires great care t)n the part of the antesthetizer, and some surgeons even go so far as to assert that complete antesthesia at such times should not he jtroduced.' The pain and terror, however, of abdominal section, the struggles of the patient, the general horrors of the situation, would seem to demand the use of the antesthetic, even though the risk be grave. In such a case, before the anaesthetic be given, the stomach .should always be thoroughly emptied, and no more of the vapor should be inhaled than is absolutely necessary ; rapidity of action on the part of the surgeon becomes a matter of great moment, since the danger increases in almost geometrical ratio with prolongation of the ansesthesia. Ether is usually preferable to chloroform, thougli not rarely it is a very good pi'actice to begin the ansesthetization with chloroform and afterward maintain it with cth(>r. Kidneys. — Writing in 1890, Dr. Lawrence Turnbull said that "it is of the greatest importance that attention should be given to tlie condi- tion of the kidneys, and an examination made of the urine when an ana?sthetic is to be administered. Deaths, unaccountable otherwise, are due to this cause. In diseases of the kidneys, the blood being loaded with urea, ana?stheti<'s almost invariably produce convulsions, coma, and death." These words of Dr. Turnbull reflect a widespread pn>fessional ojjinion. If, then, disease of the kidneys be so strong a contraindication to the use of anesthetics, it is necessary to examine very carefully as to the jiroper choice of the anaesthetic when, notwithstanding the existence of renal disease, ansesthesia must be superinduced. It is jilain that two distinct dangers underlie the use of the ansesthetic in renal disease : one has to do with the influence of the drug upon the diseased kidneys ; the other has to do ^vith the relations between the secondary conditions of Bright's disease and the anaesthetic. Markedly atheromatous arteries ■contraindicate nitrous oxide ; a degenerated heart-muscle contraindicates chloroform ; and it may very well be that sometimes the choice of the surgeon shoidd light uj>on the anjesthetic which threatens the kidneys most, because it is the least dangerous to those organs which have become secased. As throwing light upon sudden death during antesthesia it is worthy of note that in Dr._ Geo. B. ^\^)0(^s experiments," referred to lielow, several times in dogs who were suffijring from nephritis artificially ]>ro- duced by the use of cantharides or present as the outcome of natural disease sudden fatal arrest of respiration occurred, suggesting that there may be in urremia or uriemic conditions a special inability of the respi- ratory centres to resist the eflect of narcotic poisons, and that anu>ngst the secondary effects of Bright's disease should be put lack of resistive power in the respiratory centres. ' See British Med. Journ., March, 1892. » Univ. Med. May., vi., 189-1, p. 802. 662 ANESTHESIA. Ill attcmptintj to dcfidc as to the clioicc of an anresthctic for an urse- inio patient it is pro[)fr first to stmly tlic relations of the aiuestlietic to the ividneys themselves. So far as my reading goes, Dr. Thos. A. Emmet of New York was the first to call attention to the possibility of the pro- duction of fatal suppression of urine in persons suffering from chronic Briglit's disease by the use of ether. In his first experience complete suppression, and death in three days from nrpemia, occurred in a patient suffering from ciiroiiic cystitis and probably renal degeneration. Subse- quently to this Dr. Emmet is said to have had five such cases. Without attempting to go over the whole literature of the subject, attention may be called to the cases rcjiortcd by Professor W. F. Norris to the Amer- ican Ophthalinolooieal Society in 1881, especially to the one in -which death in convulsions followed ether anaesthesia in a child suflering from fatty kidneys, and in which after death the kidneys were found intensely congested. Various cases similar to these have been pultlished in med- ical literature, and it does not suffice to answer, as has been done, that ether has been frequently employed in Bright's disease without bad results. It ought to be possible positively to determine whetlier or not ether is capable of affecting tlie secreting structure of the normal kidney. In the British Medical JouvnaP Dr. Lawson Tait records a remarkable case in which, the ureters being exposed, it was found that the contin- uous administration of ether prevented the secretion of urine, and so- long as the narcosis persisted there was no flow of urine. This obser- vation is said to have been repeatedly confirmed by Tait himself,- and is of great importance as evidence that ether does affect the human kidney. It is evident that experiments upon animals should be made, in which, the ureters having been exposed and canulated, it should be determined whether these observations of Tait are exceptional or not. Albuminuria after ordinary anresthcsia is probably rare, but it certainly does occur at times. Patein' found it once in every three cases, but this is plainly much above the average. In elaborate studies made in the physiological laboratory of the Univei'sity of Pennsylvania by my son. Dr. Geo. B. Wood,^ it was found in dogs that during ether anses- thesia the kidneys become markedly congested, and almost invariably, if the anfesthesia had been protracted over fifteen minutes and the dog then" killed, it was possible to demonstrate cloudy swelling of the nuclei and contents of the secreting cells. The cells of the convoluted tubules were those primarily affected, the tufts and corresponding tubules only showing change when the antesthesia had been greatly prolonged. It is true that Fueter'^ fliiled to detect changes in the kidneys of etherized dogs, but this negative testimony can hardly stand against the positive evidence with specimens which were studied and accepted as conclusive by Dr. Guiteras, professor of pathology in the University of Pennsyl- vania. These researches and studies may seem to the reader at first sight to demonstrate that chloroform is the safer anaesthetic when renal disease exists. The case is not, however, so clear, for it has undoubtedly been shown that chloroform itself has a very deleterious influence upon the ' Vol. ii., 1880. " London Lancet, .Ian., 1883.

Alhuminuria has been iioticeil hotli in man and in animals after eiiioroform nareosis.' Dr. Eugene Fraenkcl ^ has fotuKl that after death from protraeted ehldroform narcosis the seereting renal epithelium is in a condition of profound degeneration — a conclusion which he subsequently confirms, stating^ that the alteration in the kid- ney epithelium is never wanting after death from prolonged chloro- formization. It would seem, therefore, that botii ether and chloroform have a dis- tinct deleterious infinence upon the kidneys. I am myself inclined to believe that of the two agents ether is the more dangerous to the kid- neys, especially on account of the great quantity which it is necessary to use. The second division of the present subject concerns the relation of the an£esthctic to the secondary ett'ects of kidney disease. The most dangerous of these secontlary effects, so far as anesthetics are concerned, and the one which almost invariably occurs if the patient live long enough, is degeneration of the heart-muscle. It is very evident that when this is present chloroform is a much more dangerous anjesthetic than is ether ; indeed, under such circumstances the danger from chloroform grows extreme robably by the coinci- dent action of the shock of the operation itself, of the emotional strain, and of the various depressing factors inseparal)le from a surgical illness. Disturbances of Renal Secretion. — The subject of the action of anaesthetics upon the kidney structure has already been, I think, suf- ficiently discussed in connection with the cpiestion as to the influence of disease upon the choice of an aniesthetic. Many years ago a well-known Philadelphia surgeon attributed the diabetes which occurred, and finally proved fatal, in his own person to the inhalation of nitrous oxide, and in 1886 the French writer. Dr. Lafont,- affirmed that he had seen abortion with death of the foetus occur at the moment of anaesthesia from nitrous oxide, and that he had noticed chlorosis, albuminuria, and especially true diabetes, follow the inhalation of the gas. He especially warns against the possible ]>roduc- tion of diabetes mellitus, reporting a case in which sugar appeared in the urine twice after use of the gas ; and also stating that he had been enabled to produce glycosuria in the dog and also in his own person by the inhalation. The high blood-pressure which occurs during the nitrous- oxide narcosis is without doubt attended with venous stasis, and it does not seem, a priori, impossible to have as an after-effect of such narcosis various symptoms produced by change in the cerebral centres. On the other hand, nitrous-oxide anesthesia has been produced so many millions of times that, if it were really often the cause of serious after-effects, it seems hardly possible but that overwhelming evidence would be at this time forthcoming ; and careful inquiry made by myself of persons whose sole business has been for years the administration of nitrous oxide for the extraction of teeth shows that in no instance have patients returned to them with complaints.

At ])rcscnt, therefore, it would .seem that when the patient is a normal individual the surgeon should have no fear of any after-eifects from nitrous oxide. Disturbances of the Liver. — Frericiis states that jaundice some- times follows the inhalation of chloroform and ether, but such cases must be of exceeding rarity. I have myself never met with tliem in litera- ture, and Murchison states that after careful examination he has never been able to find a record of a case. On the otiier hand, Bernstein,' and also Levden,^ have found traces of bile-|)igment in the human urine after chloroform narcosis ; and Nothnagel ' has recognized biliary coloring matters in the urine of rabbits after subcutaneous injection of chloroform or ether; but Kappeler^ in twenty-five cases of chloroform narcosis was not al)le to obtain a trace of biliary coloring matter ; further, ciiloroforra mixed with blood outside of tiie body raj)idly destroys the red corpusi'les, liberating iia?moglobin, and it is possible tiiat in rare cases of protracted chloroform narcosis some such action occurs within the body, yielding icteric products. On the whole, it does not seem probable that chloro- form lias any important influence upon tiie liver, save only as part of the wides})rcad action upon the tissues next to be spoken of. The General Nutrition. — As long ago as 1850, Caspar mentioned fthronic poisoning by means of chloroform, and somewhat later Liman affirmed that after 2>rolonged chloroformization patients sometimes pass into an abnormal condition whicli continues for days, even for weeks, and finally ends in deatii, tlie whole being tiie result of the influence of the cidoroform. These views met with little acceptance, and, indeed, seemed eonnnonly to have been overlooked or disregarded, until Dr. E. Ungar demonstrated by experiments upon the lower animals that prolonged chloroform narcosis has a profound influence upon the general nutrition.^ He found that in the dog, when narcosis was kept up for many hours and repeated once or twice at short intervals, tiiere was a widespread fatty degeneration, usually of a very liigh grade, in tlie heart-muscle and in tlie liver and kidneys, but more or less pronounced in the spleen, in the general epithelial tissues, in the voluntary nuiscles, and, in fact, in all of the higher tissues. That this change was not secondary to any alteration in tlie blood by the chloroform is believed by Ungar to be shown by the fact that no change could be noted in the red blood-cor- puscles, nor were bile acids to l)e found in the urine, nor was there ever any h;emoglobinuria. These researches have been confirmed in their general results in numerous exjieriments npon animals by Strassmami,^ by Ostertag,'' and bv Kast and Mcster.**' Further, in a series of very careful studies upon four human subjects dying after prolonged chloroformization Dr. Eugene FraenkeP has fi)und a widespread necrotic degeneration, associated with ' Muleschatf.1 Uidersuchungen, 1870.

In further conlirmation of the powerful iuthience of cliloroform on nutrition there are the observations of Salkowsivi, that marked increase in the output of nitrogenous waste is caused by the administration of the drug to dogs; of Kust and Mester, that there is a marked increase in the elimination of chlorine and nitrogen produced by the auiustlictic ; and of Petruschky, that after death from ehlorcjform the intercellular juices become rapidly acid. Ostertag in his conclusions differs some- what from Ungar in believing that the fatty degeneration is in part due to the destruction of the red blood-corpuscles by the chloroform. As, however, he also believes that the destruction of the protoj)lasm is in part effected by the direct influence of the chloroform, the difference between his views and those of Ungar is not vital. Moreover, whatever of scientific interest may attach to the method in which chloroform pro- duces its ravages, to the surgeon the method is of little practical import- ance, the vital fact l)eing that chloroform itself, directly or indirectly, destroys the living protoplasm in almost all portions of the human body. It seems to me, therefore, that it nuist be considered an estiiblished fact that a prolonged inhalation of chloroform directly affects the general nutrition of the vital organs, and is capable in this way of causing organic changes which may produce death very soon after the inhalation, or may take days or even weeks to work out the fatal result. Certainly, enough has been made out in regard to the action of chlo- roform upon the nutrition to condenui the present total disregard by practical surgeons ( if this influence. When the amiesthesia is of short dura- tion the influence of the chloroform uj)on nutrition is probably of little or no importance, but in those operations which require one or several hours for their performance the matter seems very serious. In such a case it is essential to sele(.'t that ansesthetic which has the least influence upon nutrition. Unfortunately, though we know so much in regard to chloro- form, we have no positive knowledge in regard to ether. Undoubtedly, it shares the power of chloroform of destroying the red blood-corpuscles and setting free the oxyhemoglobin in freshly-drawn blood, but beyond this we have no evidence. A-priori reasoning, however, leads to the be- lief that ether probably disturbs nutrition much less than does chloroform. The researches of A. Zeller' indicate that chloroform is in part at least decomposed in the system. Chlorine is chemically very closely allied to iodine ; the deleterious influences upon protoplasm of the iodine com- j)ounds set free by the decomposition of iodoform are well known ; prob- ably the chlorine compounds set free by the decomposition of chloroform act similarly. There is also much reason for tlie belief that bromide of ethvl is lial)le to be decomposed in the system and to yield bromme compounds capable of seriously att'ecting nutrition. Ether is not eliminated to any ajipreciable extent by the kidneys : in the experiments of Dr. Geo. B. ^\'ood it was found that whilst one drop of ether could be detected in two ounces of urine by the process used, no ether whatever could be found in numerous trials in the urine drawn at the time and at varying intervals after prolonged surgical etherization. ^ Ze'U^chr. f. pJuji^ioloij. ChcmitJ, Bd. viii. ADMINISTRATION. 6G7 Tliere is, of course, much escape of etlier from tlic body through the hing-s, hut plainly it, like alcoiiol, is larirely destroyed in the organism. In its destruction it must yield the same products as does alcoiiol, and, since no deleterious compound can be educed from it, it seems highly improbable that it should affect nutrition as does chloi'oform. On the otiier hand, it is probable that the long-continued use of alcohol will cause fatty degeneration, and the matter is so important that it should be at once put to the test of experiment. In reviewing the whole subject it seems to me that, although our knowledge is imperfect, the surgeon who desires to produce a prolonged narcosis should prefer ether to chloroform, unless there be in the peculiar- ities of the individual case positive reasons to the contrary. Administration. "V^lieuever it is possible the patient should be prepared for the use of an anesthetic by an abstinence from food for at least four hours, and usually any food given inside of six hours should be very light and thoroughly digestible, so that the ana^sthetizer can be sure of the em])ti- ness of the stomach. Whenever circumstances render such preparation im])ossible, and the ansesthetic has to be given although the stomach is full, the greatest care should be exercised to prevent any of the contents of the stomach from entering the trachea. It should be remembered that vomiting may occur not only after the antesthesia, but at any time dur- ing its course, in which case the patient should be placed with the head upon one side or ])artially downward to facilitate the possibility of discharge through the mouth, (yoe ]). 060.) It is a common belief, at least in some ])ortions of America, that the administration of an ounce of whiskey or brandy before the use of the anaesthetic lessens the chances of severe nausea or vomiting. The cor- rectness of this belief is not certain, although I deem the procedure a good one. In cases in which there is any especial reason to fear the action of the anaesthetic upon the heart, a hypodermic injection of the tincture of digitalis may be administered from half an hour to an hour before the an;¥sthesia. Ten to fifteen minims thrown into the subcutaneous tissues with proper antiseptic precaution will rarely jn-oduce any local disturb- ance bevond some burning or smarting. In cases of very weak heart it would probablv he wiser to begin to produce the influence of the digitalis twelve to twenty-four hours before the administration of ether. Even in ordinary cardiac cases the hypodermic use of strychnine before the inhalation may be of great service ; and when there is a general tendency toward collapse or shock atropine or strychnine should always be admin- istered to ])revent, if possible accident. The action of the various anavtlKtics is so different tiiat different methods of administration are required. Ktherizgular and stertorous and the conjunctiva insensitive (these signs usually manifest themselves in about two and a half or three minutes) the inhaler should be removed for two or three In'caths. 13. In ordinary cases it is unnecessary, in order to secure full anaesthesia, to rotate the ether reservoir beyond " 3." 14. When once full surgical anaesthesia has become established the anresthetist will be able to turn back the ether reservoir to " 2," 1^," or even " 1," and to admit air in sufficient quantities to avoid cyanosis. 15. Be careful to replenish the ether reservoir before the ether in it is exhausted. Oniifibi/ Inhaler. — 1. Wring out the sponge in warm water, and, having squeezed it as dry as possible, place it in the cage. 2. Pour upon the sponge about half an ounce of ether. 3. Very gradually bring the inhaler toward the face of the patient, and if an air-slot be used see that it is open. 4. Encourage the patient to breathe as freely as j)0ssible, and grad- ually close the air-slot. 5. Be prepared for the patient attempting to push away the inhaler, rising from the bed, etc. 6. Should the sponge freeze, another one, wrung out as before, should be substituted and fresh ether added. 7. When more ether is needed about half an ounce at a time should be added to the sponge. Except inider the most peculiar circumstances the ansesthetic should always be administered by a skilletl attendant rather than by the operating surgeon. This rule rests upon two foundations : In the first place, occa- sionally during the stage of antesthetic excitement there is sexual stim- ulation which may go on to a complete orgasm and lead to after-compli- cations if the operator and patient be of opposite sexes. In the second place, the person who gives the antesthetic must pay the strictest atten- tion during the whole period to the condition of the patient, as the life of the latter may dejiend upon the recognition of the early symptoms of accident. The celebrated Hyderabad C'ommission, in the most urgent and forcible terms, has drawn attention to the respiratory function as affording the chief seat of danger, and has asserted that failure of respiration always precedes, and is really the cause of, collapse of the circulation. There is no room for dispute as to the importance of a gradually produced asphyxia in the weakening of the heart, but cardiac depression and fiilure of circulation are just as important as is failure of the respiration, so that the ana\sthetizer who neglects the pulse is most culpable. Both respiration and circulation must be relentlessly watched. Failure of the circulation occurring at any time during ansesthesia is of most serious import, but the meaning of respiratory failure depends ujjon when it occurs. Especially is this true if ether be employed. ADMINISTRATION. G71 Early in etherization the irritating influence of the va})or upon the mucous membrane and the ftiuces of the upper respiratory tract fre- quently produces reflex disturbances or even arrest of the respiratory movements. Such an occurrence should, however, be the signal for giving the anfestiietic more freely, since tlie respii-atory disturbance is not accompanied with any danger, and is at once suspendeil ^\hcn suf- ficient of the anaesthetic has been taken to obtund the nerve-centres. On the otlier hand, any irregularities of respiration occurring after aniesthesia has been thoroughly induced imjieratively demand the imme- diate withdrawal of the anesthetic. In 1874, Dr. Baudin called atten- tion to tiie jiupil as a guide in chloroformization, stating tliat it is at first uniformly dilated, Init afterward is uniformly and immovably contracted, and tiiat the jieriod of contraction is the period for operation. Since tlie publication of Baudin's memoir the matter has been much discussed both by physiologists and clinicians. As a general rule, during deep chloroform auresthesia there is decided but not minute contraction of tlie pupil, and if during tlie antesthesia the jnipil returns to norm, more chloroform is required, but if it suddenly dilate, danger is imminent. It has been shown, however, by the experiments of Holmgren, Kratsch- mer, and others that this general rule is often departed from — that in the lower animals the pupils vary greatly during chloroformization ; and there can be no doubt that this is also true in regard to man. Sometimes the pupil dilates early in the chloroformization, and remains dilated througii the comj^lete anaesthesia ; again, nor rarely, especially wiien the operation occurs in the region of the neck, the ])upil alternately dilates and contracts during a chloroformization. During etherization the common rule is for tlie pupils to be of mode- rate size or even slightly dilated, whilst in very deep ether anesthesia there is often, perhaps commonly, pronounced dilatation. On tiie otiier hand, in a considerable projwrtion of cases the ]>u])ils contract during etiierization, whilst in other cases the size of the pupil varies very much, and often inadvertently, during one etherization. It is evident that the pupils cannot be relied upon as a guide during the administration of an anesthetic, though some inference may be derived from their study. Much more important to the anestiietizer are the color and expression of the tace. The face should be carefully watched ; any cyanotic apjiear- ance denotes ajiproaching asphyxia, whilst an excessive pallor is indica- tive of failing circulation. Severe ansesthetic accidents are often, if not usually, immediately preceded by a sudden change sweeping over the expression of the face like the alteration of the summer landscape by a flying cloud. This danger-signal is so imjwrtant, so freciuent, and so imperative that the anesthetizer should always carefully watch the countenance of the patient. The importance of a careful watch over the jiulse is so obvious as not to need any detailed discussion here, and I only call attention to the convenience of the temporal artery for the purposes of the aniesthetizcr. Any danger-signal occurring during the administration of an anes- thetic should lead to the immediate withdrawal of the inhaler and the attempt at resuscitation of the patient. The measures employed fiir the latter puiiiose of course vary according to the direction from which the danger comes. Usually the first procedure is to see that there is no 672 ANJESTHESIA. ohstriic'tioii to the respiratory passages by the tlirowiiig back of the paralyzed parts upon the larynx. Various methods have been advo- cated. Formerly all that ^vas considered necessary was simj)ly to draw forward the tongue, but Dr. Benjamin Howard showed that this does not necessarily accomplish the ]nirpose, and proposed the extension of the head and neck. In an elaboi-ate series of experiments, however, made in the lal)oratory of the University of Pennsylvania, Drs. Hobart A. Hare and Edward Martin proved that the method of Howard is often inefficient, and that the best results are to be obtained by carrying out the following rule : " Place the index finger of each hand upon the cor- responding cornua of the hyoid bone, whilst the middle fingers rest upon the angle of the jaw, and then ])ress forward and upward, the same force serving to extend the head uj>on the neck ; if this fails to open the glottis, by means of a tenaculum thrust far back into the base of the t»ngue draw it forward." Whilst the manipulation spoken of is going on an assistant should strip the chest of the patient, and by slapping it with a cold wet towel or by pouring a little ctlier over it, so as to get the effect of cold, should endeavor to stimulate respiration. If there be failure of the pulse, no time is to be lost ; inversion of the body is to be practised immediately. This method of treating anaesthetic cardiac fiiilure has been commonly claimed, especially in Europe, as having originated with the Parisian surgeon, Nelaton, but the profession is really indebted for it to an Amer- ican, Dr. E. L. Holmes t)f Chicago, who as long ago as 1868, speaking of anaesthetic accidents, said : " WJienever there is any failure of the heart's action, as is nearly always the case, the body should be laid at an angle of forty degrees, with the head downward, so as to favor the passage of arterialized blood to the brain." Inversion of the body does not, however, act as a resuscitant in the manner which was believed by Dr. Holmes and universally accepted by the profession. The series of experiments which I made for the address delivered before the Berlin Congress of 1890 demonstrated that in the body of the animal whose circulation has been paralyzed by chloroform the whole arterial and venous system acts in a measure like a single tube filled with fluid. Thus, if the feet of the dog were raised \ertically above the head M'hilst the latter remainetl n])on the table, an immediate rise of pressure always occurred in the carotid artery, even if the heart had practically ceased beating, ]irovided that the head of the animal ^^'as kept upon a level with the table — that is, upon a level with the mano- metrical tube. If, h(jwever, the head of the animal was de])ressed below the level of the table for a distance ecpial to, or greater than, the length of the body of the animal, a decrease of the arterial pressure occurred at once, although the animal was in a vertical position. The phenomena observed were precisely such as would have been produced if the canula had been inserted into a tube filled with fluid, instead of into the carotid artery, and the elevation and depression of this tube had registered itself on the recording drum in obedience to the ordinary laws of hydrostatics. The phenomena were entirely independent of any beat of the heart, and could usually be produced when the animal was dead, provided the death had not occuri-ed too long previously. Sometimes, even a very few minutes after the cessation of the heart-beat, it was impossible to ADMINISTRATION. 673 bring about the changes of pressure, pmhably because coagulation of tlic blood had occurred to an extent sufficient to interfere with the liquid properties of the fluid. In no case was any etfect upon the respiration caused by change in the position of the animal. In a number of cases, however, when the feet were elevated the heart, which had entirely ceased beating, recommenced its work, and I have several times seen a j^ulse entirely disappear when the animal \vas taken from the vertical to the horizontal position. On the other luind, very frequently it was impos- sible to afieot the cardiac action by changing the position of the animal. N(>vertheless, the restoratiou of cardiac movements occurred too fre- quently to be a mere outcome of chance, though I several times noted that tiie heart was more affected by alternately elevating and depressing the feet of the animal than by keeping it in a steadily elevated or horizontal position. The action of inversion in the ana?sthetic accident is therefore not upon the respiratory centre, but upon the heart. When the circu- lation has practically ceased in anesthesia, inverting the body must cause the blood which has collected in the extremely relaxed vessels of the abdomen to flow into the right side of the heart and distend it ; and this distention, tliis increase of intra-cardiac pressure, may at a critical mo- ment have an influence upon the failing organ sufficient to recall it into functional activity. The question of the use of drugs in tiiese accidents is, of course, an extremely important one. The more important remedies which previous to 1890 were used by clinicians for the averting of threatened death were ether, alcohol, ammonia, amyl nitrite, digitalis, atropine, and caf- feine. Although, at least in America, hypodermic injections of ether have been frequently employed, even in ether accidents, such tise is so absolutely absurd that it does not seem to me to require any exper- imental evidence of its futility. Ether in the blood acts as ether, whether it finds entrance through the lungs, through the rectum, or through the cellular tissue ; and the man who would inject ether hypo- dermically into a patient who is dying from ether should, to be logical, also saturate a sponge \\ith the ether and crowd it upon the nose and mouth of his unfortunate victim. Of all the drugs, that which was primarily most relied upon by the clinicians as a cardiac stimulant in auiesthesia was alcohol. The chemical and physiological relations of alcohol to ether and chloroform are, how- ever, so close that many years ago I became very doubtful of the value of this drug as a stimidant to a heart dejiressed by ana?sthesia. These doubts continually grew stronger from what I saw and read as to the effects of the administration of alcohol during ana?sthesia, and were finally changed into conviction by the experiments of R. Dubois,^ who found that in the animal to which alcohol has been freely given much less cldoroform is required than in the normal animal to anaesthetize or to kill; or, in other words, that alcohol intensifies the influence of chloro- form and lessens the fatal dose. In my own experiments, made for the aressure with an increase in the size of the individual pulse-beats. In several instances death was apparently averted by its injection, and I saw in one or two experiments, in which large amounts of the digitalis had been employed, sudden systolic cardiac arrest, indicating that digitalis, if in sufficient amount, is able to assert itself victoriously in opposition to chloroform. Moreover, when I have given chloroform to dogs whose hearts were already under the influence of digitalis there has seemed to be a peculiar steadying or sustaining power combating the circulatory depression naturally produced by the amesthetic, and I believe that in all cases of weak heart in man a full dose of digitalis given hypodermicallt/ before the administration of chlo- roforiii would greatly lessen the danger of cardiac collapse. With amyl nitrite, for which much has been claimed as a cardiac stimulant, I was never, in my experiments, able to obtain any rise of the arterial pressure, and very rarely any alteration in the size of the pulse-wave ; occasionally the pulse-wave did appear to be a little fuller. My own belief is that the amyl nitrite is a doubtful i-emedy '\\liich must be used with the greatest caution in ana?stlietic syncope ; certainly the least overdose most seriously adds to the dej^ression of the heart. Of all the experimental results ^vhich I reached, those with strych- nine were to me the most surprising. I found that the injection of strychnine into the jugular vein of a dog whose circulation and respira- tion were failing from an overdose of chloroform was usually followed by a gradual rise of the arterial jiressure, and always by an immediate and extraordinary increase of the rate and depth of the respiration. Thus I have seen a respiration which had [>ractically ceased for ten seconds, under the influence of the injection of strychnine become at once very ADMINISTRATION. 675 large and full and reach the rate of 130 a minute. In order to get any effect from the alkaloid, however, it is essential to give it in large doses ; to a robust adult with serious anesthetic heart or respiratory failure -^ of a grain may be given at once hypodermically. I have never performed any experiments to determine the effects of cocaine in anfesthesia, but I have proven it to be one of the most pow- erful of the respiratory stimulants, and that it is also able to act as an adjuvant to strychnine, so that in the cliloralized dog, wlien the respira- tion has bci'n raised as far as could be done with strychnine without incurring too much risk of poisoning, cocaine was able still further to improve it. I believe, therefore, that hypodermic injections of strychnine and cocaine woukl act more effectually in the accidents of aniesthesia than would either alkaloid by itself. The most rcmarkal)le results whicli I liave reached in bringing about recovery of animals to all ordinary intents and purposes dead were obtained through the use of artificial respiration. Thus I have seen an animal in which no respiratory movements whatever had taken place for two minutes, and in which during that time no movements of blood had occurred in the carotid artery, and in wiiicii, therefore, tiie heart liad practically ceased to beat, rapidly and jjermanently restored by artificial resj)iration. I have no doubt that in a large proportion of the deaths which have occurred in man from antesthesia the fotal result might have been avoided by the use of an active artificial respiration. The difficulty with artificial respiration, as it has been hitherto practised upon man after the Sylvester or other methods, is its inefficiency ; whereas the artificial respiration of the pliysit)logical laboratory is much more efficient than natural breathing in causing circulation of air through the lungs, and therefi)re in removing excess of the anajsthetic from the residual air in the lungs and from the blood. The use of what may be called " forced " artificial respiration by the physiologist so natu- rally suggested a similar practice in man that the celebrated John Hunter invented for the jmrpose an apparatus which consisted of a Ijcllows so constructed that when it was extended one compartment drew in air from the lungs, whilst the other drew air from the atmosphere, and when it was closed the process was reversed, the fresh air being thrown into the lungs, the foul air into the atmospliere. There is, however, no need of drawing the air out of the fully-filled lungs ; the chest-walls even after death, nuich more during life, have sufficient elasticity to force the air out of the lungs, and all ordinary laboratory apparatus for artificial respiration is based upon this fact. For forced artificial respiration upon man an ordinary bellows is all that is requir(>d for the motive power. In 1887, Dr. George E. Fell of Buffalo introduced the use of forced respiration to the profession as a means of treating morphine-poisoning, and devised an apparatus which consists of a pair of foot-bellows liv which air is forced into a receiving chamber, which in turn is connected with an apparatus for warming the air, and a valve which can be opened and shut by a movement of the finger. This valve in turn leads to the tracheal tube. When the valve is opened the air rushes through the chamber into the lungs and exjiands them ; the finger is lifted, the valve shuts, the lungs contract ; and so the respiration goes on. I have no doubt that this apparatus is very 67G ANESTHESIA. efficient in practice, but it seems to me to be open to the serious oI)j('('- tion of being unnecessarily com])lex and costly. A much cheaper, simpler, and probably e(|ually efficnent ajiparatus may consist simply of a ])air of bellows of proper size, a few feet of india-rubber-tubing, a face-mask, and two sizes of intubation-tubes ; there should also be set in tile rubber tubing a metal tube, similar to the ti'aciieal cauula of the physiological laboratory, so that it is in the power of the operator to allow for the escape of any excess of air thrown by the bellows. I suppose this whole apparatus could be prepared at the expense of less than five dollars, and it seems hardly necessary to point out its probable value, not only in narcotic poisonings, but in all accidents or diseases in which life is threatened by a temporary paralysis of the respiratory centres. THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SURGERY. By ABPAD G. GERSTER, M. D. I. Infection, its Agents and Carriers. Modern surgery, as uuderstood and practised to-day, has been made possible by two thinus. One was the discovery of antesthesia ; the otiier, the firm estal)lishment of the Listerian principle of snrgical cleanliness. The changes bronght about by tiie general acceptance of the Listerian principle are rarely realized by that younger generation of surgeons whose medical education was finished after 1885. The terrors of the surgical practice of those former days — terrors which surgeon and patient faced meekly and in resigned despair — ^such as unavoidable sui)puration, pyajmia, septicaemia, erysipelas, tetanus, and, worst of all, hospital gan- grene, are so rare now that some of them, notably hospital gangrene, may safely be declared to be extinct. All of them are looked upon now as exceptional and always due to ascertainable and avoidable con- ditions. Hence, even suppuration not being considered an unavoidable but rather an unusual conn)lication, the possibility of its occurrence is allotted a diminishing share in the determination of the advisability of all oj)crations. Adequately to point out the enormous practical gain due to mod- ern methods as compared with pre-Listerian results, it may suffice to state that, according to Lind]>aintncr,' "80 per cent, of all wounds" — treated in Nussbaum's clinic in Munich — " were attacked by hospital gangrene. Erysipelas was tiie order of the day to such an extent that its occurrence could almost have been looked u])on as tlic normal course ; not to suture any scalp-wound was a firm princijile ; healing by primary union did not exist, and suturing of a wound would have simply led to retention and the further encouragement of erysi])elas. Within one year 1 1 out of 1 7 patients subjected to amputation died of pyemia ; to observe the course uf a compound fracture was a great rarity in our clinic, as it was customary to perform amputation immediately, other- wise purulent infection, hos]>ital gangrene, or septicaemia led to a fatal termination within a few chiys." In Volkmann's clinic at Halle the usual rate of mortality in compound fracture was 40 per cent. To illustrate by American examples we may mention that Ashhurst" in 1881 gives a rate of mortality of 28 per cent, after 100 major ampu- tations performed by iiimsclf, judging this to be below the general average, which was al)out 33 per cent. ^Deutsche Zeitschrift fiir Chirurf/ie, 1S77. ^ Encyclopedia of Surgery, vol. i. p. G17. 677 678 THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SURGERY. What a change has taken ])hu'0 since then is attested by the reniari?- able improvement in the dcatii-rate after all forms of o])erativc work. To give an instance, it may be stated that of 318 major amj)ntations done by Volkmann under antiseptic; precautions, 28 cases ended fatally ; that is, his rate of mortality was about S) per cent.' Still another and more forcible illustration of the influence of antiseptic jirinciple.s is the report (»f Dennis conipi'ising 1000 cases of compound fracture treated by him in four large metropolitan iiospitals, covering a period of several years, with a death-rate from se[)tico-jiyiemia of \ of 1 ])er cent. This is in marked contrast to the published report in pre-antiseptic days of the Obuchow Hospital of St. Petersburg, where the death-rate reached as high as 68 per cent, in 106 cases of compound fractures; or of the Pennsylvania Hospital from 18.'31 to 1851, where the death-rate was 44 per cent, in 116 cases; or of the New York Hospital during the same period, where the mortality was 48 per cent, in 126 cases." A corresponding improvement is observable in all other branches of surgery. The lai-ge cavities of the human body are fearlessly invaded now, the cranial contents, the pleura, peritoneum, or large joints form no more a noli me tangerc, and what used to be called the surgeon's " luck" or "misfortune" is now considered to be the direct consequence of a sound or of an improper tecliniipic of cleanliness. In another direction great progress for the better has been secured, materially affecting the welfare of patients and hospital economics, inas- much as the average duration of time needed for curing most surgical complaints requiring operation has been materially reduced, To give a typical illustration, it may suffice to say that where in former days three to six months were consumed in healing the wound after ablation of the mamma, two to four weeks are at present amply sufficient for the purpose. It is a matter of curious interest to see the laborious compilation of statistical tables contained in many of the older works on surgery, in which the influence of the external temjierature, the seasons, barometric pressure, sex, nationality, or race exerted ujjon the success of operations is seriously considered. We kno^v to-day that the healing of a wound is entirely uninfluenced by these as well as b}' other factors formerly con- sidered important, such as, for instance, constitutional taint or individual predisposition. This change for the better is solely due to our know- ledge that, like fermentation and jiutrefoction, the infection of wounds is directly due to the importation anil ])roliferation of minute organisms. Protect the wound from these organisms and it will heal kindly in a tuberculous, syphilitic, or cancerous subject in man and woman, in the young and old. a. Atmospheric and Contact Infection. — The belief that the air may be, and often is, the medium of the transportation of morbid agents is as old as human tradition. The knowledge that the course of subcutaneous injuries is widely diiferent from that of open wounds was clearly expressed by John Hunter, since whose time it has assumed the character of a surgical tenet. Yet the nature of the precise agent con- tained in the atmospheric air, and notoriously injurious to Avounded tissues, remained a mystery. INIalgaigne's experiment of pumping the ' Oberst: Die Amputationen, etc., Halle, 1882. 2 Philad. Medical News, April 19, 1890. INFECTION, ITS AGENTS AND CARRIERS 679 subcutaneous tissue of animals full of atmospheric air, thus rendering them emphysematous, then fraeturinu; bones, dividing subcutaneously tendons, etc., without producing suppuration, only served to thicken the mystery. It is Lister's immortal merit to have directed surgical endeavor into the I'ight channels in utilizing the hints afforded by the labors of Pasteur and others. He showed that the decomposition (if dead organic sub- stances is due not to the gaseous, but to accidental and corpuscular, elements floating in the air. As a direct outcome of the theory that disturbances in the healing of a wound were produced by a sort of fer- mentation analogous with the decomposition observed in dead organic matter, leister endeavored to destroy tlie nocuous contents of the air by the use of his carlxtlic spray, and sought, further, to prevent the ingress of these organisms into tlie wounds by the emj)loyment of various occlu- sive measures, the tinal form of which, the typical Lister dressing, revo- lutionized surgery. Though the theory lacked scientific confirmation, the enormous improvement of the results of surgical operations done under Lister's precautions, as compared with former ones, was very appa- rent to candid oliservers. The fierce and unphilosophical opposition of Lister's countrymen did not prevent ^'olkmann from studying and benefiting by the new light issuing from Scotland, and to his unreserved and generous approbation is due the rapid acceptance of Lister's principle throughout Germany, the continent of Europe, and America. To England belongs the doubt- ful distinction of harboring the last reiunants of a truculent negation of M'hat tlie grateful world has learned to value as a great benefaction to suffering humanity. As before mentioned. Lister's theory lacked scientific proof long after its great utility had been abundantly proven in surgical practice. The actual scientific demonstration of the micro-organisms causing wound- infection, their separation and classification by secondary culture, in short, their natural history, are the outcome of the methods of research orig- inated by Robert Koch, who furnisjied the long-lacking scientific proof of the correctness of the Listerian theory. Bacteriology has shown that the air contains various micro-organisms in varying proportions and quantities, the variations being veiy great under different circumstances. AVhile l)acteria and cocci prevail in the air of inhabited dwellings, the spores of mould and the fungi of alcoholic fermentation firm the majority of the micro-organisms contained in the open air. We know that the air of cities contains more germs than that of the country ; that in diy weather there are more germs floating in the air than in rainy weather; and that tlie air carries more germs when there is wind than wiien it is calm. The air in mid-ocean, on top of the highest mountains, and in the middle of large tracts of uninhabited damp forests is practically germ-free. A sea-breeze carries fewer germs than a land- breeze.' These facts point irresistibly to the assumption, now abundantly ' Condorelli-Mangeri : " Variazioni numeriche dei micro-organismi nell' aria, etc.," Atli deW Acarleynia, etc., Catania, 1888, Ser. iii. T. xx. ; Uffelmann : " Luftuntersuchun- geii," Arcli.fiir Hygiene, Bd. viii., 1888, p. 262. 680 7-/77? TECHNIQUE OF ANTISEPTIC AND ASEPTIC SURGERY. proven, that tlic nidus of all minute orfjanit^ms i.s not the air — that they are not bred in the air, as formerly believed, but that their breeding- places are to be looked for in organie substances, mainly on the surliiee of the earth, whence they are occasidually and temjK)rarily displaced to float in the air. As soon as the disturbing agents subside the tldating germs will settle back on the surtace. (Jrganic germs \\\\\ best float in air when they assume the form of dry powder or of dust ; and Naegeli has demonstrated that they will never enter the air from fluid media by the instrumentality of ordinary agents, such as common winds or drafts of air. Hence the belief that sewer-gases may cause infectious diseases is erroneous, as the stinking air of a damp sewer contains, as a rule, fewer germs tiian the best ventilated or unven- tilated dwelling or the open street. To become dangerous the contents of the sewer or water-closet must be first dried, then pulverized, and finally wafted in air.' It may be added that micro-organisms may be carried from liquid media into, and remain susjiendcd in, the atmosphere by inordinately strong winds, .such as prevail during storms. This is explained by the tendency of strong winds to dash water against shores, to make the waves break, and thus to produce spray, which is readily transported by high winds.^ In further confirmation of the fact that dryness and agitation of the air favor the increase of the number of micro-organisms contained in it, may be mentioned the facts that C'ondorelli-Mangeri found in the air of Catania a decided increase of germs at times when a fair or otiier popular gathering was held. The relative number of germs will rapidly increase in the air of workshops after work has commenced, and the same thing is observed as to the air of barracks, Iiospital wards, and dwellings shortly after their Iieing sMcpt and dusted. Accoi'ding to Hesse, in the air of school-rooms, originally containing 3000 germs per cubic metre, their number will increase to 20,000 during school-hours, and to 40,000 when the children leave school. It is of considerable interest to note that the breath of healthy and diseased animals or human beings, be it however foul, has never been found to contain micro-organisms. The moist surfaces of the bronchi and lungs act as a filter by which germs carried into the respiratory tract are retained, the expired air being almost entirely free from germs.^ Thus we find that all microbes foiind suspended in air are derived from the exposed surfaces of organic material. In examining the relative proportion of living germs contained in sputa, pus, street-dirt, slops, and the water of open sewers and canals we encounter truly apjialling quan- tities, and far outnumbering anj-thing ever found in the foulest atmo- sphere. According to the researches made by the Berlin Hygienic Institute, each cubic centimetre of the water of the river Spree contains from 3200 to 154,000 germs, the average being 37,525.^ There are in each drop of pus millions of microbes, and similar proportions prevail as to every kind of decomposing organic material, t om])arcd \\ith tlii.?, ' Petri : " Eine neue Metliode, Bacterien-Polvsporen, etc.," Zeitsclirifl J'iir Hygiene, 1888.

INFECTION, ITS AGENTS AND CARRIERS. 681 the 40,000 germs found in a eul)ic luetre of the vitiated air of a lecture- room are truly iusignifieant. With these facts in view, the statement may readily he accepted that contact of a wound with any of these substances will involve a much greater chance of infection than exposure to atmosplieric air. And long before actual proof of these relations existed, the I'esults of actual practice had demonstrated tliat Lister's fears of aerial infection were exaggerated. Hence the early abantlonment of the carbolic spray and the later one of irrigation. The only precaution worth taking against the possibility of atmospheric contamination of a wound is the avoidance of acts tending to stir up dnst. iS\\ee})ing, dusting, and ventilating of localities to l)e shortly used for operative work is ini]>roper. These pro- cedures should be gone through with far enough ahead of the time of operation to permit the laying of the particles of dust before the opera- tion begins. Should time be lacking to fulfil this condition, it will be best not to disturb any hanging or piece of furniture, not to open doors and windows simultaneously ; in short, to avoid everything tending to stir uj) dust. b. Infective Agents. — As the sulyect of surgical bacteriology has received adequate treatment in the preceding articles of this work, it will be sufficient to point out the jjractical outcome of the labors of the bac- teriologist as far as they concern the surgeon. Though it is known that certain sul)stances, organic and inorganic, injected into living animal tissues, are apt to cause a i>rocess similar to microbial sup])uration, it is just as well known that this manner of causation is very rare, and in no wise comparable as to frequency and general importance with the forms of progressive suppuration directly dependent upon the action of the various pyogenic micro-organisms. The overwhelming majority of sup- purations, and other disturbances of a similar natui'e to which the human tissues are subject, certainly depend upon the direct influence of patho- genic germs imported from without. Their proliferation and the kical and general etiect of their products constitute what are termed " infec- tion " and " disease ; " that is, a progressive development of symptoms well defined and typical. Tliis progressive character of the symptoms accompanying tiie lodgement and proliferation of jiathogenic organisms in the living tissues is what distinguishes an infectious process from other processes similar to, but essentially different from, the former, and pro- duced by chemical, mechanical, or caloric agencies. With a full understanding of the overwhelming importance of the microbial factor in producing certain morbid states, it would yet be one- sided to attribute the production of these morbid conditions to the pres- ence of microbes alone, and to nothing else. Altliough we admit that ordinarilv tliere canntjt lie suppuration without microlics, we know, on the other hand, that the j)resence of microlies in itself will often fail to cause suppuration unless the state of the tissues themselves or the general state of health favors their germination. In M'hat this predisposition of certain tissues of a body consists we do not know ; nor can ^ve positively define wliy tlie s;ime individual will show different degrees of resistance to the same form of infection at different times. So much, however, is fairlv certain, that to account for tlie various forms of microbial infec- tion we nuist assume two nearly etpially important factors : First, the 682 THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SURGERY. lodgemont of pathogenic organisms within the living tissues ; and, sec- ondly, a condition of these tissnes favorable to the development and multiplication of microbial growth. To illustrate this relation of things it may suiiice to mention the marked predisposition to suppurative pro- cesses observed in diabetes mellitus. n. Disinfection and Sterilization. Foremost among the means for disinfection stand the homely but thoroughly efficient and sound methods of mechanical pin-ificafion, as, for instance, maceration, scrubbing, washing, scraping, shaving, M'ith or without the aid of emollients, among which the jirincipal one is soap. Being aware of the fact that the sparse number of infectious germs con- tained in the air is far outnumbered by the millions of microbes incor- porated \\ith the various forms of gross filth and dirt adherent to almost every surfoce exposed to contact with the outer world, our princijial endeavor at disinfection must be directed, in the first place, toward the removal of these gi'oss lumps of filth. How much can be acconn)lished in surgery by means of these simple methods was first demonstrated by the brilliant results of men like Lawson Tait, whose reliance was placed almost exclusively upon ordinary measures of personal and domestic cleanliness. The mechanical removal of the great bulk of microhicd dirt from the objects to be bn)Ught in contact \\ith a wound i.s the mod im- portant preparatory act of all forms of disinfection. Methods of chemical disinfection have undergone manifold changes since the davs of the universal reign of carbolic acid. Formerly, some deodorizing agents were considered good disinfectants, and the valuation of the merits of the various disinfectants was extremely uncritical. We owe the more correct appreciation of the value of these substances to the labors of Koch, who by pure culture taught us to isolate the several species of pathogenetic germs, and showed us how to recognize their dif- ferent vegetative forms. Some of these microbes are jiroductive of spores ; others are sporeless. In general, it may be said that the spores of micro-organisms offer a much greater resistance to disinfecting agents than the mother-plant, and, furthei-more, it was learned that the ditferent species of microbes also differ from each other materially in this respect. In estimating the bactericidal value of a chemical disinfectant a number of precautions ' have to be observed to eliminate errors, and dis- crimination must be used in ajijilying the results thus gained to the actual conditions met with by the sui-gcon in his practice. Another factor materially influencing the development of microbes is the presence or absence of certain cardinal conditions necessary for their proliferation. A suitable pabulum, a certain quantity of moisture, and a certain temperature are indispensable. Withdraw one or more of these conditions, and the microbes u-ill either jierish or their grorrth will be retarded. For ascertaining the relative value of a number of the common dis- infectants, as to their power of retarding bacterial growth, Koch selected the spores of the anthrax bacillus, one of the most resistant forms of ' Geppert : "Zur Lehre von den Antisepticis," Bed.

It is much easier to clieck the growth of bacteria than to kill tiiem, especially to kill them within a few minutes, which is an es.sential con- dition of the ])ractical utility of a germicidal agent. The most important of all bactericidal agents, because easily pro- cured, rapidly effective, and practical, is heat. It can be used in the form of — 1. The actual cautery ; 2. Boiling water ; 3. Steam ; 4. Hot air. The actual cautery is one of the most ancient and most effective dis- infectants. It must suffice merely to mention it here, as it properly belongs to the subject of o))crative technique. Of the other agents, boiling wafer deserves to be placed first of all. ^.s to its bactericidal' value, it is known that it icill kill spores of anthrax in two minutes, and will destroy the vegetative forms of any coccus or bacteria in from one to five seconds. Next in importance is steam., which, to be ftdly effective, must not be mixed witii air, but ought to be pure and " saturated." Steam can be used in several ways, vithev quiescent ov moving; it can be used under increased pressure or superheated. Of tiiese several forms, moving steam has been found most useful, and it will kill anthrax spores in from five to fifteen minutes. 684 THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SURGERY. Less t'flw^tivc tli;iii stc;iMi is hot :iir, to which, at a temperature of 140° Celsius, spores will siicciinih only alter an exposure of three honvs. Anotiier great drawbaek of hot air is its great inferiority of 'penetration as compared with lioiiing water and flowing steam.' The badericklal value of the commonly employed cheniieals of sur- gery falls far below that of the caloric agents just enumerated. There are \evy few chemicals which even in a concentrated state will destroy anthrax spores within twenty-lour hours. Of these may be mentioned — Bichk>ride of mercury, Iodine, Chlorine, Bromine, Trichloride of iodine, Cresol mixed with sul|)luu'ic acid. Of chemicals that require a nuich longer time to kill anthrax spores there are — Carbolic acid, 5 : 100. Creoline, Ligneous vinegar, 2 days. Chlorate of lime, 5 : 100, 5 "' Turjientine, " Formic acid, " Chloride of iron, 5: 100, " Quinine mur., 1 : 100, 10 " Arsenious acid, 1 : 1000, " Muriatic acid, 2 : 100, " Ether, sulphuric, 30 " Among substances that even after months have exerted no influence whatever upon the vitality of the spores of the bacillus of anthrax, there are — Absolute alcohol. Distilled M'ater, Chloroform, Glycerin, Benzoic acid. Ammonia, Concentrated solution of cooking salt, Chlorate of potass. (5 : 100), Alum, Borax. These lists demonstrate the remarkable insisting power of spores to the various chemical disinfectants. The vegetative forms of pathogenetic micro- organisms, the bacilli and cocci, show a much lower degree of vitality, and w ill more easily succumb to the effects of even the weaker chemicals. But under the most favorable conditions their effect is not nearly as rapid as that of boiling water, Mhieh will destroy the more resistant spores in from two to five minutes, while the effect of a 1 : 1000 solu- tion of bichloride of mercury upon the much less resistant bacilli of anthrax or upon the staphylococcus pyogenes is not assuredly destructive in fifteen minutes (Geppert). ' Wolfhiigel : MUtheUmujen aus dem Kais. Gesundheilsamt, 1881. CLEANSING OF THE SKTN AND OF MUCOUS SURFACES. 685 It \vas pointed out before that the unqualitiwl application of the results of ('X[)erinicnt to the conditions of actual surgical ]iractice would lead to serious error. While in cx]K'rinient a small (juantity of bacilli gained by pure culture and soaked into a single thread of silk is exposed to tiie effect of a large volume of the germicidal solution, in surgical j)rac- tice enormous naasses of various microbes, imbedded in solid and semi- solid tissues, sloughs, scabs, blood, fffices, grease, and dirt, are encountered by a limited quantity of the germicide. While in the experiment the germicide will penetrate, reach, and bathe every singh' individual of the micro-organisms, in practice — for instance, in a suppurating wound — only a very limited ((uantity of the vast masses of microbial matter \\\\\ come in actual contact with the solution. Finall}-, where under ex- perimental conditions the chemical action of the germicide is unim- paired by accidental disturbance, here, in the wound, most of the active princi]de of the solution will be neutralized by contact with albu- minoid components of the tissues and discharges. Hence it follows tiiat the theoretical results of experiment as to the value of this or that germicide must differ materially from those gained in actual practice. The principal substances that frustrate the usefulness of germicidal acpieous solutions are, first, a coating or adiaLrfurc offatfi/ matter impen- etrable to water ; and, secondly, the albumin contained in human tissues and their discharges, which, united with some of the strongest metallic germicides, changes them to inert albuminates and annihilates their ger- micidal properties. In estimating the practical utility of the various methods of disin- fection two questions are of the utmost importance : First, How much time is consumed by the procetlure to be effective? and, secondlj/, Will not the objects to be disinfected be damaged by the jirocess ? Where the process must lie accomplished in a few minutes, germicidal solutions are entirely inadequate, \vhile boiling is perfectly satisfactory. Where metal instruments are to be disinfected, corrosive sublimate, for instance, is inadmissible, but in the disinfection of the skin of patient and sur- geon boiling water would not be proper or agreeable. Thus it will be seen tiiat the external eonditions influencing disinfection are variable, and tiiat under changing eonditions a variation of the process of disin- fection must take place. Often — in fact, as a rule — several of the known methods of sterilization have to be combined, their application being either simultaneous or successive. To illustrate this we may mention that the patient's skin, for instance, is first macerated, then shaved, scrubbed, freed from grease by ether, and finally exposed to bichloride of mercury ; or the instruments are first soaked, then scrubbed, polished, finally boiled in sodn, solution, and so forth. m. Cleansing of the Skin and of Mucous Surfaces. The surface of the human body is a very hotbed for the ])ropagation of a great variety of micro-organisms. With the aid of a little methyl- ene blue it can be readily shown that the surface of the skin, even of a very cleanly person, is literally swarming with fungi, bacilli, and cocci. The predominance of this or that microbe is determined by the habits, 686 THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SURGERY. opciipatioii, and state of li(>altli of tlic individual.' Ilairv jilacos, as the licad, armpits, etc., and es))('cialiy the ininicdiatc nfij>liijorliood uf the natural apertures of the body, are very rieh in microbes, which become iiotahly multiplied whenever even a slight disturbance of the normal stati! of health of any portion of the skin occurs. Sweating or a slight catarrhal or eczematous condition favors tlie multij)lieation of their growth to an incredible extent, which will be still more rank in the jtresence of a suppurating wound, sinus, or ulcer. And, as we never can tell whether pathogenetic microbes are present or not, one of the most indispensable conditions of safe surgery is the scrupulous cleansing of the skin of the field of an operation and of the hands of those that are to come in contact with it. The surgeon's hand, having often unavoidable contact with unclean surfaces infected with pathological organisms, is a most connnon carrier of infection. The disinfection of the hands is not an easy or rapid process. The slipshod methods of cleansing tlie hands practised in the early period of the antiseptic era, when a scrubbing even was deemed superfluous and main reliance was placed on the efficacy of the carbolic lotion, were found to be entirely inadecpiate. Fiirbringer's excellent labors have taught us that here, as elsewhere, the action of the chemical disinfect- ants is accessory only, the chief importance belonging to the prejiaratory mechanical cleansing. The dry and crusted masses of bacterial dirt must be first softened by the use of a strong alkaline soap and hot water; the coatings of grease must be dissolved by the application of ether, benzine, or alcohol ; then the razor and scrubbing-brush have to sweep away the masses of macerated filth. Only after the large bulk of dirt has been removed by these means will the application of a ger- micidal lotion be of any use. In fact, a very careful and thorough mechanical cleansing will under most circumstances render the use of germicidal lotions supcrfuous. Simple as this jH'ocess of cleansing seems to be, its value will depend on the conscientious thoroughness with whicli it is applied, which thor- oughness again presents the most remarkable personal variations in various medical men. While with some few a sublimate lotion is a real superfluity, the cleansing processes of others are so shallow — in fact, a mere sliam — that in their ease the al)andonnient of chemicals would mean all forms of surgical disaster. And as long as the meaning of the canons of cleanliness will have to depend on the individual inter- jiretation of the practitioner, the use of chemicals cannot be excluded from sui'gical practice. The difference between what is termed asepsis and antisepsis is strik- ingly illustrated by the preceding remarks. Where mechanical and caloric measures are applicable and sufficient to the attainment of a state of freedom from micro-organisms, there we have asepticism. Where this is not the case — that is, -where, either on account of the inherent condition of the surfaces to be dealt with, or because of the low order of the conception of purity of the medical attendant, heat and scrubbing cannot or are not used to their full extent — chemicals must be accepted as a makeshift, and the process is termed antisejisis. 'Fiirbringer: " Untersuchungen iiber die Desinfection der Hiinde," Deutsche med. Woehenschrift, 1888, No. 48. CLEANSING OF THE SKIN AND OF MUCOUS SURFACES. 687 Among the several methods of disinfecting the surffcon'.i hands, this one can be conscientiously recommended : 1. Rub a sufficient quantity of green or soft soap into the hands and n{)on the bared arms ; then scrub them in hot water with a stitf brusli for one minute, paying special attention to the nails and the subungual spaces. 2. After scrubbing, the spaces under the nails must be carefully freed from all loose matter by the use of a nail-cleaner. 3. The iiands are now immersed for one minute in strong alcohol (80 per cent.). 4. Finally, they are immersed in a 1 :100() solution of bichloride of mercury for one minute, during which tiiis solution is to be well rubbed into all folds and creases by the aid of a brush. There are other raetiiods just as reliable as this one, notably that in wliich permanganate of potash is used ; but the necessity of employing oxalic acid for the decoloration of tiie epidermis, deeply stained by the manganate salt, is a great drawback to its use. Similar principles jirevail in cleansinff the skin of the patient, with some important modifications rendered necessary by unusually adherent deposits of dirt : 1. The skin is shaved, not only in the armpits, on the head, flice, pubic and anal regions, but wherever an operation is to be performed. 2. Whenever possible a general bath should precede the consequent steps. 3. Where, as on the hands of laboring-men, or on the feet of people accustomed to go barefoot, or in persons of unusual uncleanliness, tiie deposit of dirty e])iderniis is very thick and massive, the parts should be envelo])ed for several hours in a wet jiack of soajj-water, by which the epidermal coating will Ije sufficiently macerated to yield to tiie scruli- bing-brush. 4. Friction with water, soap and brush, and ether must then be applied until all crumbs and flakes of loose epidermis are removed and the skin becomes clean and glossy. 5. Finally, the skin is rubbed off with a 1 :1000 solution of Ijichlo- ride of mercury. We cannot leave this subject without devoting a few remarks to the tools and substances used for cleansing, notably to soap and brushes. Eiselsberg ' ascertained that all fiirnis of soap manufactured by a process of boiling are, as a rule, germ-free ; on tlie other hand, soap produced by a cold process of blending tiie alkali with fats is unreliable and sliould be shunned. As to inrushes, it will need no special jiroof — though this lias been abundantly furnished. by Schimmclbusch " — tiiat after having been used in contact with filthy surfaces, with blood, pus, and faeces, they must become ciiarged with enormous masses of noxious germs. The destruction of tiiese germs by diemical agents alone is uncertain and reipiires a verv long time. On tlie r)tlier iiand, a short boiling of five minutes in jilain water or in water ciiarged with 1 per cent, of common soda will surely render any brush germ-free. The cheap brushes made of vegetable fibre should ' " ITeber den Keimgehalt von Soilen, etc.," Wiener med. Woclienscliri/t, 18S7, No. 29. 2 Archiv fib- CKiruryic, 1891, pp. 1(13-170. (588 THE TECHXIQUE OF ANTISEPTIC AND ASEPTIC SURGERY. receive the preference, because hnislies made of bristles are claniap;e(l by boiliiifi'. The brushes used in an operating-room should be boiled every day with the instruments. Those that were used in contact with sej)tic material should either be set aside or nuist be immediately boiled bctbre being used again. After boiling in soda solution the brushes should be kept immersed in a 1:1000 solution of sublimate. The brushes eni- jiloyed on the washstantls of liospital wards or bed-rooms also need fre- quent boiling. The dcaimng of mucous surfaces with a view to their disinfection i.s a much more difficult matter than that of the outer skin, and here the use of chemical germicides is strictly limited by the dangers of absorp- tion and poisoning. Hence tlie jirocesses of wiping, flushing, and the mechanical remoral of fa;ces or mucus, together with measures directed against the escape fif tieces, bile, or urine during an operation, as by i)hig- ging or temporary ligature, will deserve the preference over germicidal lotions. IV. The Sterilization of Instruments. For preparing instruments for an operation their mechanical cleansing from lilood, pus, shreds of fibrin and tissues, or caseous or greasy material by soa})-water and a brush must be the initiatory step. Though by these means the bulk of the noxious substances clinging to the irregular sur- faces of the instruments will certainly be dislodged, yet a sufficient quantity of microbes will still adhere to them to menace the welfare of the wound.' Hence to render the instruments perfectly germ-free some- thing more will have to be done. What is desired is a mcthfid that is adequate and practical — that is, not consuming too much time or injurious to the instrumeuts. To eflect an adequate sterilization of metal instruments hot air, steam, or boiling in water can be considered. The first is impractical, as it de- mands special and bulky apparatus and consumes considerable time.^ The second is objectionable, because it rusts the instruments. The third — that is, boiling — is simple, rapid, and adequate. Its objectionable feature — that is, the rusting of the instruments — has been admirably eliminated by Davidsohn's and Schimmelbusch's exjjedient of charging the water with cooking soda in tlie jiroportion of 1 per cent, of its quan- tity. The presence of the soda will not only prevent rusting, but also will render the disinfection more tliorougli and rapid.^ To test this very question Schimmelbusch ^ has impregnated strands of silken and woollen thread with pus and pure cultures of staphylococcus pyogenes aureus, of the bacillus pyocyaneus, and with anthrax spores, after which they were immersed for varying lengths of time in a boiling soda solution. It was found that, ^vithout exception, the micro-organisms contained in pus, as well as the staphylococcus and bacillus pyocj'aneus, were destroyed in from two to three seconds, whereas the spores of anthrax which had re- sisted the effect of steam heated to 100° Celsius for twelve minutes were • Schimmelbusch : Berliner Uin.

DRESSINGS. 691 impiiro may lead to serious disturbances of tlie liealing of a wound. A brief ])reliniinary boiling in a teaspoon over a lamp- or gas-flame will be I'ound a rcuily means of destroying germs contained in any of these solu- tions. Where larger (juantities are to be preserved, an addition of a few ps of concentrated carbolic acid to, say, an ounce of solution will be fountl very useful. As to the syringes themselves, it must be said that they are, as a rule, easily infected and very hard to keep clean, especially those made of hard rubber and having leather washers. Koch's balloon .syringe is easilv cleansed and reliable, but not useful for the purposes of tile .surgeon, and is far surpassed by tlie old-fashioned barrel-syringe. Overlach has constructed a barrel-syringe whicii has a compressible rubber ])ist(in, glass barrel, and metal mountings. This instrument can be Ixiiled without injury and can be easily made aseptic. To study the value of the various ordinary methods of cleansing hypodermic svringes Schimmclbusch ' first thorf)Ughly sterilized an Overlacii syringe, then tilled it with pus, emptied it, then repeatedly tilled it with and emptied it of distilled water. Tile number of cocci was thus materially diminished, but after ten fillings and emptyings the ejected water still contained thousands of germs. A 3 per cent, solution of carbolic acid, 1 : 2000 of corrosive sublimate, and absolute alcohol gave somewhat better results, but the best of all was squirting hoUing water through tiie syringe. After the instrument was thus filled and enij)tied five times it was found absdluteiy sterile. Tlie iiolldw needles used for injection and aspiration are liest disin- fected by boiling in soda .solution. Drawing them through an alcohol flame will certainly sterilize them, but also will destroy their temper, as they are made of steel. Platinum-iridium canulas will withstand red heat excellently, but are expensive. V. Dressings. In oiiserving the course of one of the many small wounds accident- ally inflicted upon ourselves with a clean instrument, of a wound left entirely to itself and not interfered with in any way, we shall get the model of repair which is the iotash lye, liy which process sa- ponification of the oily matter contained in the cotton fibre is effected. The cheese-cloth is rinsed in cold water, and after drying possesses con- siderable though not as high absorbent power as the bleached manufac- tured article of trade. The second and most indispensable condition which mu.st be fulfilled before any dressing material is fit for surgical use is a complete freedom from pfdhof/cnetie (/ermf;. Our present knowledge of the ])art ])layed by noxious germs in the causation of wound diseases has fully confirmed the epigrammatic saying of Volkmann, that the human organism is not a test-tube filled with gelatin or agar-agar. We know that not every contact with noxious germs must inevitably lead to infection ; but, on the other hand, we also DRESSINGS. 693 know how promptly the streptococcus of" erysipelas, for instance, will enter the lymphatics through a superficial denudation. Hence measures at rendering our dressings germ-free must be considered important indeed. Freedom from germs of the gauze sold in neat tin boxes by various wholesale drug firms is, though expressly guaranteed, very unrelial)le. ^\^nd if we consider the ordinary methods of mamifa<^ture and trade, we shall not expect too much from that source. Fortunately, we have at our connnand ready and prompt means for rendering dressing materials aseptic. Of these, impregnation of the fabric used for dressings icith chemicals must be first mentioned. Lister's first efi'orts were made in this direction when he saturated gauze with a resinous mixture chargctl witJi carljolic acid. Later, corrosive sublimate displaced carbolic acid, but most of the objections justly raised against the former also applied to the latter. Aside from the fact that the ordinary processes of imj)regnation gave verv unequal results, tlic objection that carbolic acid eva])(>rated from the dressings was etpialled by the fact that the mercurial salt was also evan- escent, and, moreover, was liable to decomposition. Furthermore, the serious drawback became only too often evident that both of these irritated the skin, protlueing very acrid eczemata, and often led to raoi"e or less dangerous states of intoxication due to direct absor])tion by the blood. The simple fact that impregnation or sterilization was not the last, but the first, step in the preparation of the dressings, and that it was followed by more or less unavoidable handling by attendants and nurses in the course of drying, foldiug, cutting, and storing of the gauze, made this plan extremely unrelialile. Most of these objections disappear when we employ heat for steril- izing dressings. Here all the cutting and folding can be done in advance ; the prepared dressings are sterilized and left until needed in the wrap or receptacle in which tiiey were subjected to the influence of heat. Should, however, circumstances compel the practitioner to rely upon chemical sterilization, it is best to impregnate the dressings immediately preceding their use. Sublimate deserves the preference over cai'bolic acid, and the strength of the solution should be 1 : 2000. In hospital practice, and where the conveniences can be easily pro- cured, sterilizing by sleaui has nuich to commend it, but in an emergency am/ fabric to be sterilized extempore can be made reliably aseptic by boiling for fifteen minutes in a 1^ per cent, solution of mishing soda in water. For steam sterilization excellent aud sim])le apparatuses have been devised, their prineij)le being mainly derived from Koch's sterilizer. In hospitals an existing steam-])lant can be conveniently connected with the sterilizer, in which all the dressing materials, gowns, roller bandages, aprons, etc. needed for the day may receive their purification just before use. The ])rinciples upon which all useful sterilizers of large size must be constructed are these : 1. Tiie objects to be disinfected must receive a j)reparatory warming within the apparatus to prevent precipitation of steam. I)il4 THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SURGERY. 2. Tlic steani iiiiist enter the iippiiratus i'roiii aljovc and not from below. 3. The steam nmst liave a certain degree of tension. 4. The dressings must be dry when tiiey leave the apparatus. Preparatory warming is inij)ortant, because the contac-t of hot steam with cold dressings will produce condensation, and the dressings will become damp or even wet. This pre])aratory warming is secured by a double jacket to the apparatus. Steam circniatcs through this and warms tlu' contents of the central s])ace before this is entered by steam. Gruber, Frosch, and Clarenbach have demonstrated that when steam enters the disinfecting space of an apparatus from below the atmospheric air is not driven out at once and as uniformly as ^^■hen the steam enters from above. The cause of this is the fact that air, being heavier than hot steam, will naturallv tend to return to the bottom of the a])paratus in eddies, much of the steam escaping directly above, without uiiit()rmly jjcrmeating the entire enclosure. When steam enters from above the air is displaced gradually, uniformly, and steadily. Teuscher's observations, made on an ajiparatus that admitted steam either from above or from below, showed tiiat, steam being admitted from below, tlie recjuisite tem- perature of 100° Celsius was reached in twenty -two minutes and twenty seconds, whereas if the steam entered from above the same temperature was registered after seventeen minutes. A slightly increased tension, which is gained by resistance offered to the escape of the steam through the apparatus itself, is useful, because Fig. 175. -2_ ■» J t ) pr (Front view.

Tiiey permit of a combined sterilizatiou both of instruments by boiling in soda solu- tion and of dressings in the escaping steam. For hospital use Lautenschlager's apparatus Mill answer admirably. Schinnnell)usch's capsules or boxes, proviiled with a number of lateral holes which can be opened or closed by a single sliding arrangement, have been found extremely useful. The number of these boxes to be pro- vided de])ends upon the amount of operative work rcgularlv done in a given institution. All Box fur dressing. the dressings, bandages, gowns, etc. pertaining to one operation are placed in one of these boxes, which is then closed. The lateral aper- tures are thrown open and the box is put in tiie sterilizer. Having been exposed to the action of steam for thirty minutes, the box is removed from the sterilizer, tlie lateral holes are closed, and now the box with its contents can be left hermetically sealed until the moment wiien the dressings are actually needed. A large apparatus will hold six or eight such boxes, and, the handling of the dressings having all been done before sterilizing, these will come to the wound in an ideally clean condition. It was pointed out before, that, to be admissible, a dressing must have the (piality of preventing the undue multiplication of pathogenetic germs in the discharges by which it becomes permeated, or even have a direct germicidal influence upon those germs that are natui-ally contained in the secretions. Formerly we endeavored to accomplish this by im- pregnation with chemical agents, as, for instance, carbolic acid or cor- rosive sublimate. But the defects of this plan, developed in the course Fig. 177. Willy Meyer's portable sterilizer. of actual practice, and mentioned before, are so serious and important that the necessity of an inipni\'ement was keenly felt everywhere. j\.s an expression of this must be taken the long series of trials witii various chemicals, whici), iiowever, but strengtiiened tiie distrust felt toward them.

Xeuber demonstrated in actual practice that a dressing, however soaked Fig. 180. full with the first discharges of a fresh wound, remained perfectly sweet for an indefinite time Fig. 181. LiLutunsfhlujicr's sturilizur: StliimiiiLlliiiM.li's dressing-box. if by rapid evaporation a drying up of the discharges was brought about. The crusted discharges thus formed a sort of aseptic seal, like DRESSINGS. G!I7 the dried blood-clot in the small wound we have used as an illustration at the beginning- of this paper. Practically, the wound by this process was converted into a subcutaneous injury. But all this refers only to fresh wounds, the discharges of which are serous, thin, and not septic. Where we have to deal with suppiu-ating wounds, with secretions that are thick, viscid, and often contain consid- erable masses of deeomjiosing detritus and slough, rapid evaporation and inspissation become a drawback. First, the dressings cannot readily absorb the discharges, which remain pent up, as it were, altout the orifice of the wound. As soon as evaporation leads to crusting, these discharges become sealed, and retention with all its harmful consequences is the direct effect. Here, then, woLs-t dressingf!, the jH'evention of evap- oration by the use of impermeable coverings, and frequent changes of dressing accompanied by a thorough cleansing of the wound, represent the order to be followed. Wherever, for various reasons, it is needed to ])ack or tampon a wound, moist treatment is preferable to the dr}-, and here imj)regna- tion of the packings ^vith Iodoform is highly convenient. The inhib- itory action of iodoform upon the development of the ordinary micro- organisms of suppuration is still unexplained, but is not doubted by any practical surgeon. IMosetig-Moorhof tirst demonstrated its great eftieacy in preventing septic processes in wounds freely conmuuiicating with the orifices of the digestive tract, notably the oral cavity. Subse- cjuently it was emploj-ed with great success in wounds around the anus and rectum or the vagina or bladder ; finally in wound-cavities of any description that recpiired temporary or prolonged packing, ultimately even in the peritoneal cavity (Mikulicz). But whenever iodoform is employed it must be used with caution, especially in anajmic and elderly subjects, as dangertuis fiirms of intoxi- cation are apt to follow its indiscriminate and unrestricted exhibition. Another drawback is the tendency of iodoform to ]iroduce in certain persons an angry eczema. The iodoform powder itself may be the carrier of infection ; hence it ought to be washed in a solution of corrosive sublimate before use. The best method of impregnation of dressings with iodoform is the mechan- ical one, which is preferable to that by the use of ethereal solutions, which are very apt to decompose. Crystalline powder of iodoform is simply scattered as evenly as possible over the moistened gauze, then rubbed into its meshes by luuul. (xauze thus ])repared nuist be kept in a tight receptacle to prevent its drying, which is still furtiier j)rcvented by the addition of a little glycerin to the plain boiled water used for moistening. Light will also tend to decompose iodoform ; hence the powder and iodoform gauze ought to be kejit in vessels that exclude When iodoform gauze is badly borne, or where its use is contraindi- cated for other reasons, the powder of siihnitratc of bismuth might be advantageously substituted ; or the gauze might be moistened with either a 3 per cent, solution of cwctate of alumina (Burow's solution) or a 1 per cent, solution of chloride of zinc. In regard to the technique of tamponade the following hints may be found useful : The width and Icny-th of the strips of ffiuize used for G!).S THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SUROERY. jiiickings should be regulated by the shape and extent of the cavity to be Hllcd. Each rcocss ought to receive a strip of its own ]iacked down loosely and its end lirouglit out, corresponding to the location of the recess. The end of each stri|) must ]>rotrude from the wound, otluTwise it might become lost. When very large cavities are to Ite treated, it might be objectionable to use the large amount of iodoform gauze retpu- site for filling the space. Here an ample compress of iodoform gauze ought to be made to serve as a /iniiif/ of the cavity, the central space being filled with strips of jilain or medicated gauze other than iodoform. The oozing of serum out of tamponaded wounds is often very copious. Plere the superficial dressings slnjuld he changed frequently. After the lapse of twice or three times twenty-four hours the packings have to be removed or renewed when secondary sutures are contemplated — as, for instance, from amputation wounds or the peritoneal cavity. From the mouth, larynx, circumrectal sjtaces, or the bladder the packings are not removed until they become loosened, unless special indications compel their earlier withdrawal. Whenever the packings of a septic wound are removed, it is well to observe a system or order in removing them. As soon as a strip is removed it ought to be replaced at once by another clean strip, then another strip is removed and replaced, and so on until the entire wound is cared for ; otherwise recesses might be overlooked and thus give rise to retention. Where special precaution is demanded, as, for instance, in the removal of tamjions covering intestinal sutures, these tampons must be marked by tying a knot in their distal end. As most of the dressing material used by the general practitioner is necessarily derived from drug-stores, it would seem very desirable for the manufacturers of dressings to adopt a method of sterilization by steam, according to which the dressings, put up previously in suitable paper or muslin packages, were to be subjected to sterilization irithiit oikI together vufh their c/oaed wrappings. Thus the contents of each package would certainly remain sterile until needed. VI. Sponges and their Substitutes. For the rapid and thorough removal, during the progress of various operations, of blood, and in some instances of pus, sponges are indis- pensable. All the ditferent substitutes that have been suggested instead of sponges lack the imique qualities of a good sponge. Its softness, the avidity with which it absorbs liquids, and the readiness with which it yields them on pressure, are all due to the incomparal:)le elasticity and porousness of its substance. Fortunately, we liave in this country a cheap and abundant snjiply of reef spniu/es, chiefly In-ought from Florida. and the Bahamas. They possess all the main qualities of a good sponge, and, being very inexpensive (about $2.00 to |2.50 a pound), need not be used oftener than once in aseptic cases. Those saved from an aseptic operation can be resterilized, and are excellent for operations on septic wounds. The difficulty of a reliable disinfection of sponges has been well rec- ognized by practical surgeons since early times, and the search after a good method of cleansing has resulted in a number of propositions. One of the oldest procedures is as follows : The sponges are thoroughly freed SPONGES AXD THEIR SUBSTITUTES. iiW from calcareous matter by beatintr witli a stick ; are then immersed for twenty-four hours in a watery sokitiou of permanganate of potash, 1 : 500, from \\ hich they are transferred into a 1 per cent, sokition of subsulphate of soda, to which is added pure muriatic acid in the propor- tion of 8 per cent, of the volume of the subsulphate-of-soda solution. Tliis bleaches the sponges and frees them of the renuiant of calcareous dust. After this follows a thorougii rinsing in water and immersion in a 5 per cent, solution of carlxilic acid, and the lunger the bt'tter, as a short immersion is often insutticient for a thorougii sterilization.' Kiinmiel's plan is very much simpler, but still less reliable. How- ever, it would be improper to condemn it altogether, as it has been found excellent and very reliable after the addition of a few simj)le improve- ments of the method. Gerster's modification of Kiimmel's method is as follows : The sponges are beaten, then immersed for twenty-four hours in an 8 per cent, solution of muriatic acid to free them of calcareous sand. After this they are rinsed in cold water and put in a closed jar filled with water in a warm place for three days. During this time the spores con- tained in the meshes of the sponge all germinat(% and thus become more sensitive to the infiuence of germicides, and hardened collections of tilth are also macerated and softt'ued. After three days the sjionges are thrown into a vessel containing hot water, and each sponge is thoroughly kneaded and rubbed with green soap, which carries the maceration and softening of the dirt adhering to the meshes to such a point that most of it is removed by a subsequent rinsing in cold water. Each sponge is now dipped in alcohol, S(jueezed, and thrown into a jar containing either a solution of corrosive sublimate 1 :1000, or a o per cent, solution of carbolic acid, in which it remains until needed, (^n account of the pre- cipitation of the mercurial salt the sublimate solution ought to be re- newed every few weeks. In carbolic acid, which is more durable, the sponges are apt to turn brown, which, however, does not diminish their usefulness. The simplest and most conveni(>nt mode of disinfection by boiling in soda solution cannot be employed with sjionges, as their softness and elasticity are destroyed by excessive hardening and shrinkage. Dry heat will sterilize them thoroughly, but will also cause shrinking and hardening unless the sponge is first freed from every trace of atmo- spheric moisture — a somewhat difficult and impracticable process. Schimmelbnsch - has devised the simplest and best mode of disinfect- ing sponges, which has stood the severest tests both of practical expe- rience and of bacteriological scrutiny. The sponges are first freed from sand in the usual manner, then ai'e rinsed in cold water, in which they are left to macerate "for a week or so. After this they are cleansed of gross dirt by washing in warm water, from wliich they are taken and enclosed in a nuislin bag. In the mean time a suitable quantitv of a 1 per cent, soda solution is brought to the boiling-point in a pot or boiler. As soon as it is boiling freely the pot is withdrawn from the fire, and into this scalding solution the bag of sjjonges is immersed for thirty ' Frisch : " Ueber Desinfection von Seide und Schwiimmen," Arckiv fiir klin.

The soda solution will retain u teni]>eratiire of from 80 to DO degrees Celsius for a considerable time, and tiiis is sufficient to destroy all germs, even the \erv resistant an- thra.x s])ores, within ten minutes (Beliring). After thirty minutes tiie l)ag is removed from the l)oiler, and the sponges arc lilicratcd of their c<»ntents of s(Kla by rinsing in plain Itoiled water, which should be done while the sponges are still within the bag.

Fin. 184. Vn. Sutures and Ligatures. The substances used for tying vessels and for the appro.ximation of the edges of wounds by suture are either absorbable or nou-absorbalde. Non-absorbable are silk, silkworm gut, cotton thread, hor.se-hair, and silver wire. Their sterilization can be reliably done either by boiling in soda solution or by exposure to a current of steam, the former at the same time with the instruments, the latter with the dressings. The non-irritant quality of any one of these sub- stances depends entirely and solely upon their freedom from noxious germs, and on nothing else. Hence if they are to be buried in the tissues it is advisable to sulijcct silk and silver wire to a thorough disinfection juxt before use. Tiie silk employed in suturing may be .steril- ized once, and then preserved in a tight vessel containing citlier carbolic or sublimate solution. Of absorbable threads there are catgut and ktingaroo tendon (Marcy). The endeavor of the older surgi'ons to gain an al)sorI)ali]e material for ligatures led to the tentative eiiij>loymciit of buckskin, the aorta of the ox, fresh intestinal fibre, fresh tendon, and raw hide ; and the Metni case for steam-sterilized great advantage of a material that, after hav- dry silk (SeliimiiK'lt)iisch). v /. i . , ^ ,. t -j.! a ing ))eriormed its tunction, ih.sappears without any further aid, is very evident. Moreover, it is well known that many aseptically buried silk or wire threads will ultimately work out to tiie surface, though this may happen without active suppuration. Hence we owe a debt of gratitude to Lister, who .systematically iiitro- SUTUEES AXD LIGATURES. (01 duced animal or oatji'iit ligatures into surgical practice. Catgut, long since in use on musical instruments and in certain trades, is made of the fibrous portion of the nuiseularis of the small intestine of sheep. The process of maceration, liy which the nuieous, serous, and circular Fig. is.-,. (ilass jar U>v wet cat^ait or silk. muscular constituents of the intestinal wall are prepared for their mechanical removal, involves decomposition, and ]>ermeation with mil- lions of miero-organisius, aioong which the spores and Itacilli of anthrax may be and have been represented (Volkmann). Therefore a thorough disinfection of catgut becomes one of the most important desiderata of clean surgery. Of Lister's original method, of disinfection by immer- sion in carbolized oil, it need only be said that it is entirely inadequate, and has been universally abandoned. Lixter'n vhromichcd citfr/uf offers more security against infection, because chromic acid, a strong germicide, is employed in addition to carbolic acid, and the solutions used are aqueous, not oleaginous; hence much more etfective. The object of the addition of chromic acid, how- ever, was not the attainment of a more complete asepticism, but a hard- ening of the gut to prevent its too rajiid or ])remature absorption. Chromicized catgut is prepared as follows : To a 5 per cent, carbolic- acid watery solution is added crystalline chromic aciatient came very near losing her life by acute sepsis inadver- tently carried into the wound at the time of the operation from a neigh- boring patient suffering from acute osteomyelitis. Before the wound was examined extensive sloughing of the fasciie and of the outer skin took place. From tubular drainage where thick, consistent, and rojiy masses of ))us are to be carried out of a cavity, to capillary or no drainage where a perfectly dry and asejitic wound treated without chemicals promises to remain dry and aseptic, the transitions and gradations are many, and their proper selection and adaptation must depend on the skill and judg- ment of the surgeon. Whatever material is to be employed for drainage, it is indispensable that it should be made absolutely sterile before use. ' "Uelier Catgiitinfection," Bdlrdge. filr hlin. Ckir.

LOTIONS, IRRIGATING SOLUTIONS, ETC. 703 Neuber's absorbable drainage-tubes, prepared out of decalcined ox- bones, and siuiilur ones made of the lonjj bones of large l)irds (Trendelen- burg, ^laeEweu), have all been abandoned as inipraetieal. Glass drain- age-tubes are very neat and clean, and can be readily sterilized, btit are rigid, fragile, and cannot be shortened to suit varying conditions ; hence they have come into use only here and there. Rubber drainage-tubes are still considered the most adaptable, cheap, and useful material for wound- drainage. Their disinfection can be safely done by boiling for five minutes in soda solution (1 per cent.) or by steaming during fifteen to twcutv minutes. Tiiis will not harm the rubber. After disinfection the tubes ought to be preserved by preference in a 5 per cent, solution of carbolic acid, which will not become inert by contact with rubber, as will corrosive sublimate. The best receptacle is a tall fruit-jar. The tubes should be cut into proper lengths — that is. a little shorter than the height of the jar — and are to be put in ujjright — that is, standing on end — to facilitate removal. IX. Lotions, Irrigating Solutions, and Antiseptic Powders. Water, the usual solvent in preparing lotions, is never free from germs when found in its natural state in springs, wells, running water, ponds, lakes, and the ocean. Only in the state of very deep ground-water and as atmospheric vapor is it known to be germless. As soon as it apjjroaches the earth's surface, either from below (sjirings) or from above (rain), it becomes ciiarged with micro-organisms, which are often pathogenetic. Sea-water also contains pathogenetic germs near the shores, where it mingles with the drainage of inhabited areas of land. To be admissible for surgical use water must be freed from its mici'obial contents. This can be done by precipitation, by filtration, by boiling, and, finally, by the addition of chemical germicides. Finely-])owdered insoluble substances mixed with water will, on set- tling to the bottom, carry with them into the sediment a certain propor- tion of the microbes suspended in the water. The finer the powder and the slower the process of sedimentation, the better will the water be purifieil, but ;i perfect state of sterility can never be reached by this method. Filtration by the various usual methods will very materially diminish the number of germs contained in the water from lakes and rivers. The filters of the waterworks of the city of Berlin, for instance, are .so effect- ive as to reduce the number of microbes contained in a cubic centimetre of the water of the river .Spree from hundreds of thousands to an aver- age of from fifty to seventy. Here the filtering-beds are made of gravel and sand. But even where tight porous vessels made of ])ottcr's earth (Chamberland-Pasteur) or of "an impalpable powder (like Kicselguhr ' ) are used, the certainty of an alisolutc detention of all microbes in the filtering medium is assured only for a certain time. In addition to this, large (luantities of water cannot be treated by tliis method in a practical manner. Boiling is far superior to either sedimentation or filtering. Almost all of the germs contained in water are surely destroyed by boiling for '■ Nordtmayer: " I'eber Wasserliltration," Zeituchrift fiir Hi/i/iene, vol. .x., IS'Jl, j). 1-15. 704 THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SVIUIERY. five minutes, and tliis ajiplies to tlic dirtiest :is well as to the cleanest water. Dor and Vinay,' who boiled the water of tiie river Khone, eontainin>j an average of 33,000 germs per litre, found that only 941 of them survived tiic process ; that is, more than 97 per cent, were destroyed. In addition to this it must be said that the germs eapal^le of surviving the ordeal of boiling are not pathological ; as, for instance, the hay l)aeillus. The method commends itself for its simplicity, safety, and general appli- cability ; hence in important cases it will be good for the surgeon to provide an ample quantity of boiled water. The dipper or pitcher to be used for ladling should be boiled together with the water. In hospi- tals running hot water is provided from a central boiler. But even this simple method of sterilizing water bv boiling is not always applicalde ; therefore it is very convenient to have another, more ready way of accomplishing the same result by the addition of a chem- ical germicide to the water. On account of the fact that the microbes contained in ordinary pure water are widely distributed, and not collected in dense masses, hence freely accessible from all sides, their destruction by chemicals readily dissolved in the medium is not difficult. Not so easy is the disinfection of the turbid and much-polluted waters of canals, ponds, and stagnant pools located near human hal)itations. The cause of this is to be sought in the fact that these waters contain smaller and larger lumps of gross dirt of varying density, aggregations of organic matter teeming with microbial life. To render chemical disinfection possible, such water must be first })urged of gross filth by filtration. iShould this not be feasible, boiling will have to be resorted to, and w ill prove even here fully effective. Where only the mechanical effect of a lotion is desired, as in many aseptic operations, the phj'siologically nnirritant solution of common cooking salt, 6 to sterilized water 1000, Mill be found convenient. This solution does not cause smarting in a fresh wound. The most effective and most useful of all chemical germicides is corro/iive sublimate, suggetited by Koch and introduced into surgical practice by Berg- mann. It is a very poisonous and very cheap ^vhite, crystalline, odorless powder, readily dissolved in water and promj>tly decomposed by contact with metals. Hence it cannot be used for the disinfection of instruments, nor can it be kept in metallic vessels. As connnou drinking-water often holds in solution considerable quantities of the alkaline earths, notably lime, which eagerly decompose the mercurial salt, forming insoluble deposits, it is necessary to counteract this tendency by the addition to the solution of some acid. Either acetic or tartaric acid, or finally com- mon cooking salt, will perform this service, a good rule being to take either of these correctives in the same proportion as the corrosive sulj- limate. To a 1 : 1000 solution, for instance, would be taken 1 gramme of corrosive sublimate, 1 gramme of cooking salt, and 1000 grammes of water. Corrosive sublimate is used in solutions of 1 : 5000 f)r continuous irrigation during prolonged operations about the anus ; 1 : 2000 and 1 : 1000 for washing septic wounds, and for disinfecting the skin of patient and surgeon; 1 : 500 for the final disinfection of bone-cavities after necrotomy to prepai'e them for Schede's plan of after-treatment. ' " De la sterilisation de I'eau, etc.," Lyon medical, 1889, No. 23. LOTIONS, IRRIGATING SOLUTIONS, ETC. 705 A very convenient mode of preparing snblimate solutions is that by means of sublimate tablets sold by the drug-firms. Transportation and dosage are very easy. In the absence of tablets the surgeon will prepare a concentrated alcoliollc laothcr-solufion, from wliieh tiie weaker solutions are made as reipiired. A 10 per cent, solution w\\\ be found very useful and not too bulky. Two teaspoonfuls of this, added to a cjuart of water, will give the proportion of about 1 : 1000. For the transportation of this strong solution a glass-stoppered bottle in a wooden case will be needed. The symptoms of systemic sublimate poisoning, caused by indis- criminate use, are those of an intense enteritis with colicky, often bloody, stools and salivation. Local irritation, assuming the form of an angry dermatitis, is often caused by moist sublimate dressings. Carbolic acid, Lister's original disinfectant, forms colorless crystals when undissolved. It is volatile and strongly corrosive. Solutions are prepared as follows : The crystalline acid is liquefied by moderate heat; then water is ails, clonic muscular spasms, pulselessness, suppression of urine, and intestinal hemorrhages often lead to a fatal termination. The skin is also very sensitive to carbolic acid, often responding to its irritant action liy fiorid eczema. Strong solutions of carbolic acid applied to small members, as the fingers and toes, often cause a dry form of gangrene. Creolin, mixed with water, forms a milky lotion, which is about three times as eifective as carbolic acid. The usual prop(irtions are 1 and 2 per cent. Its odor is very disagreeable, but it is non-poisonous. Lysol, like carl)olic acid and creolin, is a coal-tar pi'oduct. It is a poisonous, soapy liquid, which yields a somewhat less turbid solution with water than creolin, and is about as effective. Salici/lic acid (Thiersch), a good, though weak, non-poisonous anti- se])tic powder of white color, is intensely irritating to the nasal and bron- cliial mucous membranes. In combination with boric acid it firms the poptdar T/iirrsch solution: salicvlic acid 2 parts, boric acid 12 pai'ts, hot water 1000 parts. Acetate of alumina (Burow's solution), a very effective, adstringent, and deodorizing antiseptic, is especially useful where the skin is very vulnerable and apt to become eczematous under the dressings. It is also nuich used in phlegmonous affections requiring permanent immersion or irrigation. A 1 per cent, solution is prepared by mixing 24 granunes of alum with -''S grammes of sugar of lead in 1000 grammes of water. After twenty-four hours the clear part siiould be decanted from the insoluble sedijuent. Vol. I.— to 70C THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SUIlCEUy. Tlij/mol (Ranke), a mild, n()n-])oisonoiis antiseptic of ])k'asaiit odor, non-irritant, is used in the stren<;tii of 1 : 1000. l\'nitaiif/an(ii<' of jiotaxli is a very soluble, mild disinfectant, and a strono; deodorizer, but of evanescent effect, as it is prdiiijitlv ileeoni- posed by contact with the secretions. It is used in the strength of from 1 :500 to 1 : 2000 as a month-wash and as an irrit^atinfj fluid for the urethra and bladder. Chlorine, a very jiowerful antiseptic, is used in the sliajie oi' rhlor'nu- water. Peroxide of hi/drogen (Troninisdorff ), a very strong antiseptic fluid, non-poisonous, is used in the strength of 8 per cent, for the disinl'eetiou of suppurating and ill-smelling wounds ; is also a good sty])tic. Certain aniline dyes, as methyl-blue and pyoktanin (Stilling), are of undoul)ted antiseptic value in the treatment of ulcerating and sloughing malignant new growths. Among the antiseptic powders, iodoform is to be flrst mentioned. It is a light-yellow, crystalline powder of peculiar odor, non-soluble in water, soluble in alcohol, ether, and some oils. Its antiseptic ]iro])erties are developed indirectly by contact with the products of microbial decom- position (ptomaines and toxalbmnin). Their chemical actii)n liberates a certain [u-oportion of free iodine, which inhibits a further development of microbes. It is very poisonous, especially to elderly and antemic subjects, and often is also very irritant to the skin. Its offensive odor can be effectively masked by an admixture of burnt-coffee powder and .some aromatic oils. It is used for dusting the line of union of a sutured wound, and most effectively in the vicinity of the natural a])ertures of the human Ixidy, where perfect asepsis is not attainable. In tiic sha]ie of iodoform glycerin, from 10 to 20 per cent., it is injected with good effect into tuberculous foci. A.s iodoform gauze it is an indispensable aid in treating wounds communicating with the oral cavity, the rectum, vagina, and bladder, in the temjwrary tamjxjnade preceding secondary .suture, in forming a protective dam against infection of the healthy ])eri- toneum in operations for appendicitis; finally, in plugging irregular denuded cavities caused by various intra-abdominal ojicrations. The symptoms of iodoforni-poisoning are rubescence of the skin, headache, dejection, nausea, and vomiting ; in the more serious cases, sleeplessness* great frequency of the ))ulse, restlessness, fever, delirium, maniacal attacks, finally coma and convulsions. In these cases iodine is found in the urine, in wiiieli its jm-scnce is demonstrated by the addi- tion of dilute sulphuric acid and fuming nitric acid, together with a small quantity of chloroform. If this mixture is violently shaken, the chloroform assumes a purjile color under the influence of free iodine. Subnitrafe of bi.wuitli (Kocher) is a good antiseptic powder, though somewhat poisonous if used in large quantities. It is a strong exsic- cative. Xaphtlwline (E. Fischer) is also a good, non-poisonous, but very ill- smelling, antiseptic ])owder. Oxide of zinc, a mild antiseptic powder, is one of the components of Socin's paste, which is used for a covering of small sutured ^\•ounds of the face, instead of regular gauze dressings. Its formula is : oxide of zinc, 50 grammes ; chloride of zinc, 5 grammes ; Avater, 50 grammes.

The fiirnitnre, uperating and other taldcs, should be constructed of iron and glass, and should l)c kept tidy and Itrigiit by frequent wasiiing and the apjilication of white enamel jiaiiit. The floor should be a gently inclined plane and water-tigiit, atfordiiig the possibility of an unstinted use of water. The sterilizing apparatus for instruments and dressings has to be within comfortalile reach of the operating-table ; tlie instru- ment-cases, constructed of enamelled iron and glass, ought to be in a side room, as the al)undant use of water ami steam in the operating- room, however favorable against the creation of dust, is apt to cause rusting. For the reception of soiled linen a covered and enamelled metal receptacle is to be provided ; fin" catching pus, ichor, urine, cystic and other pathological fluids, glass pus-basins and co^•ercd l)uckets will be needed. All of these must be innnediately removed from the ope- rating-room with their contents, and should not be suflcrod to remain there longer tiian unavoidably necessary. The dressings sliould be kept in the closed metal boxes in which they were sterilized until the moment when they are actually needed for use. For the storing and use of the various irrigating fluids an iron-and- glass stand is needed, on which are disposed suitable bottles, the con- tents of which can be readily brought to the wound by means of rubber tubing and glass nozzles. An ample supply of glass vessels and trays, of smaller and larger size, for the laying out of instruments and for the rinsing of hands and sponges in antiseptic or aseptic fluids during the course of an operation, forms a necessary complement of the outfit of the operating-room. Where the operating-room serves the purposes of teaching, the Fig. 187. Simple operating-table (Rotter). benches and seats provided for the audience should be of the simplest kind, admitting of an easy mode of cleansing by the watering-hose and mop. OPERATING-ROOM AND SICK-ROOM. 709 Separate operating-rooin.s for septic and for aseptic cases are very desirable, as by attending to septic cases in strictly separate rooms, furnished with distinctly separate sets of instruments, the chances of accidental infection of clean wounds will be considerably diminished. Should this dualism be impossible, and there be only one room in which laparotomies, artiirotomics, and operations for j)lile!jnionous atlections must be dealt with one after the other, then the invariable rule ought to prevail, to do the aseptic operations first, and to leave the work on septic wounds to the last. When, in private practice, a living-room of the dwelling of the patient is to serve as an operating-room, it will be impossible to ci'eate Fig. 188. Table for instruments and dressings (Rotter). conditions of such exquisite cleanliness as are demanded by, and indis- pensable in, the tainted surroundings of a hospital. And, luckilv, they ar(> not necessary, as it is known that the atmosphere and dust of private dwellings contain much fewer pathogenetic germs than those of hospitals. It is a good rule, however, to select that one of a set of rooms wliich is least inhabited, and not to disturb the furniture and hangings unless this — that is, theii- removal — can be done from six to eight lK)urs ]>receding the time of tiie operation. In short, unless the clearing and cleansing of tiie room be done a good while before the operation, giving ample time for the settling of the dust, it is better simply to cover the tables to be used with clean white cloths, to wipe chairs with a wet towel, and to avoid every unnecessary disturbance of the rest of the furniture that may tend to stir up dust. Sick-rooms or sici--iranl.-i require a similar management ; that is, scrupulous attention to cleanliness, facilitated by the practical simplicity of the utensils and fiu'uisiiings. Glass and iron deserve the preference over .so-called artistic furniture, and all unnecessary hangings and orna- ments should be eschewed, especially where we have to deal with infec- tious forms of disease, as, for instance, di])htheiMa, profuse supjinrations, typhoid and other fevers, etc. In wards the floors should be eitlier tiled or maile of terrazzo, and tiien covered witli rugs in a suitable manner, or, if they are to be of wood, the work should be dose-jointed and the sur- 710 THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SURGERY. face kept ln'iii'lit ami liiylily ])iilisli((l or cuvcred witli a frequently- renewed eoat iif paint. Abundant and (•iiMif(irtal)lc liatliiiii;' provisions fonn an indispensable eoncdinitant of [jvopcrly furnisiied wards and siek-rooins. The c/iangc of (Ircn.siiujx is an important function involving some risk, and therefore must be surrounded by adequate safeguards. Tlie first one of these is the strict separation of patients Avith infected wounds from those whose wounds are aseptic. Sliould this be imjios- sil)le, tiien the clean cases ougiit to be attended to first, the infected ones attended to the last in seipicnce. Wlien there is a great accumula- tion of patients, many of whom require the change of extensive and bulky dressings, it is very desirable, for many reasons, to have a sepa- rate room, a so-called " dressing-room," for the renewal of all larger dressings, or, in tlie absence of this, to change dressings in the operat- ing-room. The advantages accruing from tliis plan are — first, the avoid- ance of excitement among the rest of the ]>atients, who witness the fear and outcries of the individual whose dressings are being changed ; secondly, small corrections of the state of the wound, such as incisions, dilatation of sinuses, etc., can be at once performed as required, and more readily than in the wards ; thirdly, the soiling of the floors and bedding and the raising of dust from the dressings removed are avoided in the wards. Another safeguard, too often neglected in our hospitals, is this : that surgical rounds, necessitating the exposure of wounds, shoidd not be made directly after the methodical sweeping and dusting. Every year at least once, l>ut preferably twice or three times, each ward should be completely cleared of ]iatients and furniture, and receive a very thorough cleansing by the scrul)l)ing-brush, soap, whitewash, and fresh paint. No great reliance should be placed in this animal house- cleaning upon chemical methods of disinfection, as, for instance, fumi- gations with suljihur, chlorine, or sublimate, or washings with antiseptic lotions. As it is known that the germs of infection are imbedded in gross masses of dirt encrusting the surfaces of walls, floors, door-knobs, furniture, etc., the rational thing to do is a thoroughgoing mcchanmd c/('fn(s/?jr/ of all these articles with hot soda-and-soap solutions and by the scrubbing-brush, to be followed by the application of a fresh coat of jiaint. Such a radical cleansing of a ward or sick-room might be ren- dered necessary at any time by the a]ipearance of erysipelas or other forms of infection with an epidemic tendency. XI. Aseptic and Antiseptic Operating and After-treatment. To illustrate in a coherent manner the progress of an aseptic operation we shall take as an example the account of an amputation of the female breast. Assuming that the operation is to lie done in the middle of the day, the patient should receive only a light liquid breakfast early in the morning. The operation should be preceded by a full bath if possible, and a careful shaving and scrubbing with soap and water of the field of operation, which then should be enveloped in a moist pack of towels dipped in a weak sublimate or carbolized solution. After this a clean ASEPTIC AND ANTISEPTIC OPERATING, ETC. 711 set of iiiidur-clotliiug is donned h\ tlie patient, who is now ready for the o])eration. As a matter of course, on the day preceding the opera- tion a hixative is administered. In tlie mean time, tlie operating-room is prepared. The instruments to he used are hoiked and arranged in glass trays tiUed with a weak car- bolic solution (1 or '1 per cent.), which, like all the other utensils, are placed on glass tables previously spread with clean sheets. Ligatures, sutures, and the thermo-cautery (its handle wrapped with sterilized gauze), are put conveniently in readiness. Likewise enamelled or glass basins containiugu 1 : 2()t)0 solution of corrosive sublimate, or, when theabdomen is invaded, boro-salieylic solution, are prepared for the fre(|uent rinsing of the surgeon's hands. A suit^ able number of sterilized sponges are thrown intoaclean glass basin, alongside of which stands another basin tilled with hot sterile water lor rinsing them of l)lood. The dressings are arranged on another table in the closed receptacles within which they were steamed, Fig. 190. 0|)fmting-liabit of surgeon. Operating-liabit of nurse. or, siioidd steaming be impossible, are cut and folded in the order in winch they are to be apjilicd to the wound, and are then wrapj)ed in a clean towel ready for u.-.e. 712 THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SURGERY.

Ethei' nia.puration would inevitably follow. A massive blood-clot in the wound is dangerous l)ccausc it serves as a culture medium to accidentally-entered microbes, and because it jirevents con- tact of the living walls of the wound. It must be added, however, that as we are better able to produce really aseptic wonnds, so in propor- tion the danger from this source is diminishing. Were this not so, then a healing uiulcr the hlood-c/of, as observed in irregular hollow wounds treated according to Schede's method, would l)c an impossibility. The second desideratum in the treatment of fresh wounds is the prevention of the accumulation and retention of bloody serum. This also is a good jiabulmn for the growth of micro-organisms and tends to separate the walls of the wounlish ettective drainage, especially in deep, sinuous wounds and in those the walls of which cannot l)e kcjit in actual contact by external pressure or by buried sutures. Whether the means of drainage should be a gauze wick or a drainage-tube, or merely the leaving open of an angle of the wound, or sparingly-employed sutures, — this nmst be left to the skill and judgment of the surgeon. The selection of the site of the drainage is also an important one, a dependent situation being preferable. (Jood ilraiuage will keep the wound dry and empty — will permit its walls to remain in close contact. It will prevent 71 J' the infected area not be included in the eschar, the disease 'will continue to advance. Where the escharotic has destroyed all of the infected mass the fever and the local irritation will diminish or cease at once. Where very extended areas are involved tlie ;t]>])licati(in of chemical escharotics is forbidden on account of their poisonous t'tl'ect. AYe have seen that escharotics, however reliable and excellent, admit only of a limited application ; further, we have shown in former sections of this paper that the influence of weaker solutions of the useful germi- cides is very superficial, non-penetrating, and is furthermore restricted by the danger of poisoning by absorption. Let us now examine what further means the surgeon possesses for the elimination of septic material from the tissues of the human body. Here, as well as in the practice of asepsis, mechanical measures are of the first and, utmost importance. By mechanical measures we under- stand — 1. Incisions. — Tlieir object is first to relieve tension. To do this they must be very ample and free, and should penetrate that layer of tissues beneath which is situated the cause of tension. In osteomyelitis the periosteum and cortical layer of the affected bone must be laid open to relieve tension ; in subfascial phlegmon the fascia, in glandular phlegmon the glandular capsule, must be freely split to give relief. Very often in tlie most malignant forms of deep-seated phlegmonous inflammation free and deep incisions for the relief of tension are urgently indicated very long before any defined abscess and fiuctuation could develop. To wait for fluctuation in these cases means simply a sacrifice of the patient. If an early and ample incision is made in a bad case of deep-seated phlegmon — for instance, in Ludwig's angina — the knife will divide a nearly bloodless, recently necrosed, intensely foetid and septic mass of indurated tissue, from which no pus, only a limited quantity of ichor, will escape. The second object of incisions is the evaeuedioit of li(]uid, semi-liquid, and solid products of suppuration. More or less thickened pus, shreddy and often considerable masses of necrosed fascia, must be evacuated. To aid the first evacuation of abscesses irric/ation of the cavity may be employed. As the mechanical effect of the irrigating stream is the one we want, its chemical effect being insignificant, irrigation nuist be based on correct hydrostatics, which will enable a stron;/ current of solution or plain boiled water to sweep through the cavity, carrying with it all the pus and detritus. Two incisions (counter-incision), or, where only one incision is feasil)le, the introduction of two parallel drainage-tubes, one used for the influx, the other for the outflow of the irrigating fluid, will be more efficient tiian one single tube. Irrigation tIiroit(/h a single tube ought to be done cuutiou,4y, so as not to cause over-disfeidion and rupture of the walls of the abscess-cavity — a warning especially to be heeded in ACCIDENTAL WOUNDS AND EMERGENCY DRESSINGS. 721 abscesses near tlic peritoneum and pleura. Evacuation of an abscess should never be aided by squeezing and pressure, as they are barbarous and might lead to further and serious infection. Drainage of abscess-cavities through incisions by means of rubber or glass tubes or a gauze packing /.s imporfanf, and h indicated as long as the u-alls of the earlfi/ continne to slicd effete or dead material. The tubes should be ample and should occupy the most dcixMideut position, so as to carry away the discharges by the aid of the force of gi'avity by the shortest and most direct route. They must be placed so as not to be liable to be expelled, and should not impinge on nerves or vessels. Their daily cleansing and revision — to extract large masses of sloughing tissues, for instance — are imperative. Likewise, insjji-^sation by evap- oration at their external orifices must be prevented bi/ means of moist dressings, otherwise retention might ensue in sjiite of drainage. As soon as the discharges become serous and limpid the cleansing of the cavity is finished, and the drainage-tubes should be removed. Drainage bij packing, usually with iodoform gauze, is indicated where the whoif extent of an infectei>lications. TJicrcfore, all forms of first aid given to the wounded nuist he of ^ucli a character as not to compromise the possibly aseptic character of tlie injury. HastLi and unprepared e.rji/oratlons by finger or probe are abso/ute/i/ reprehensible and useless, as their ordinary consequence is an infection of the deeper parts of the wound. The efforts of the surgeon sliould be directed toward a protection of the wound bv an aseptic dressing, which, n]i]ili<'d with a niodcrato amount of pressure, will sufiice to check ordinary liemorrliage.

Spanish windlass. the immediate requirements for hiemostasis until the transfer of the patient to his home or to a hospital is completed. Should a fracture be jjresent, the application of a splint in addition to the occlusive dressing is all that is required. Injury of the large vessels of the neck or groin, requiring imme- diate pressure by the tinger-tip in the bottom of the wound, is extremely rare. Here, of course, we have no choice, as time is precious and a few minutes of unchecked hemorrhage may result in the patient's death. But this class of cases is the only one where the introduction of an uncleansed finger might be pardonable. Washing or rinsing of an accidental wound with styptics, caustic solutions, vinegar, arnica, or even the polluted water of a well, spring, river, or canal, is also injudicious, as it is useless and may carry infection into the wound. The wisest thing to dt) is to wipe away the blood and dirt from the vicinity of the wound, which ought theu to he covered with a clean, newly-washed, and ironed cloth, fastened down with a few turns of roller bandage or hrmly tied on with a handkerchief. If time and cii'cumstances permit, sterilized or iodoformed gauze should be pro- cured for this first dressing. As soon as the patient is in his home or in a hospital, the permanent disposal of the indications arising from the injury will be iu order. The parts will have to be prejiared as for any operation according to tlie priuci])les described in the preceding sections, and then the necessary operative steps can be safely taken. Small penetrating Avounds of the extremities, caused by penetration BEGIONAL TECHNIQUE. 723 of fractured bones or by gunshot, unless arterial hemorrhage demand Inral or proximal deligation, will not need anything but thorough eleansing of the neighl)orhood of the wound, together witii an occlusive aseptic dressing. Large lacerated and contused wounds, much soiled by contact with street-dirt, will require careful cleansing after complete exposure of all soiled recesses, followed by drainage and a suitable dressing, with or without fixation. Under the application of these principles the results achieved by the surgeon in cases of compound fracture and of gunshot injury are excellent. Xm. Regional Technique. The general rules governing aseptic and antisejitic practice everv- where must be somewhat supplemented whenever certain special regions are invaded. The careful dismfcction of the oral caviti/ is a most important preparation for all operations to be done in the mouth and the adjoin- ing hollow spaces. A foul set of teeth, accompanied bv acute or chronic gingivitis, an ichorous discharge caused by necrosis — syphilitic or other — of the nasal, maxillary, or palatal liones, are serious counter-indica- tions to any operation not imperatively needed. The extraction of decaying teeth or of sequestra, the curing of acute or chronic stomatitis or rhinitis, ought to precede every important operation to be performed in the mouth or nose. Cleansing of the teeth by tooth-brush and todtli- powder — in short, a careful oral toilette — is here indispensable. In some cases of excessively neglected oral hygiene it will be even necessary to subject the patient to a systematic jireliminary treatment before attempt- ing an operation the success of which depends on a faultless primary union ; as, for instance, uranoplasty and staphylorrhaphy. The after-treatment of many oral operations has been robbed of most of its terrors by the employment of tiie permanent iodoform ijauze pack. This, though ])ermeated with tlie discharges, will protect the wound most effectively against septic infection. It should be left undisturl)cd until it becomes loosened by the granulations, when usually the dangers of infection are overcome. It is remarkable how closely an iodoform gauze dressing will cling to the wound-surface. To pull it away before it is S'jiontaneously loosened will not only cause considerable jiain, often also hemorrhage, but will especially expose the fresii wound to septic influ- ences, which afterward are very hard to combat. The cavities of the human body, — namely, the mibaraehnoidal space, pleura, peritoneum, and the large joints — also require special care, as their infection is followed by most serious, often fatal, consequences. A\ hen the .*/.•*/// is to be opened, xharine/ of the entire head is absolutely indisjiensable. In aildition to this the scalp should be well scrubbed, and tiicn enclosed in a wet paeiv, which has to remain in sitii until the patient is anaisthetized. After the removal of the wet pack the head is once more scrubbed with soap and water to get rid of all loose ejiidcr- mis. Where a cerebral ahucesa is looked for, the exposed brain should be well protected by an iodoform gauze dam before the abscess is incised. After the incision of the abscess all shreds of pus must be carefully 724 THE TECHNIQUE OF ANTISEPTIC AND ASEPTIC SURGERY. washed away with a strong jet of irrigating fluid — a wealv sublimate sohition — before the paclvings are removed. Whenever the jj/cura nr the pcrifoneum is acckleufa/lj/ injured during tlie progress of an o])eration it is good praetiee to paeii an iddoiorm gauze eomjiress into tiie rent, to be h'ft tiiere until it can be closed by suture, or, if this be impossible, for a longer ])erio(l of time. This packing will not only protect the serous surfaces against infection, but in the peritoneal cavity M'ill also prevent prolapse of intestine. Whenever accidental soiling by the escape of pus or cystic fluid or fseces is to be feared, ihc Jicid of operation our/ht to be effectirely walled off from the red of the peritoneal or pleural cariti/ Iji/ a ra reftdl tj-con- strueted dam of iodoform (jauze. Many intestinal operations can be done entirely outside of the abdominal cavity, for which purpose it is advisable to withdraw from the belly the jiortion of gut to be ope- rated on, if such a step be feasible. All ojierations upon the intestine should be ])receded, if possible, by a careful preparation. Systematic laxation witli tiie administration of lifpiid food should cleanse and leave the bowel comparatively empty. The stomach will need siphoning and washing \\henc\'cr fecal vomit exists in cases of intestinal obstruction. Likewise will gastro-enterostomy or pylorectomy need a preliminary careful toilette of the stomach. Lavage is best done with a (iilOOO salt solution. During intestinal operations involving enterorriiaphv the greatest care must be exercised to prevent soiling of the held of operation by fasces. The intestinal coil to be operated on is stripped of its fecal con- tents by finger pressure ; two ligatures — one proximal, one distal — are applied to prevent the escape of faeces, and the fecal matter still con- tained in tlie immediate vicinity of the intestinal wound is wiped away by sponges or pads of dry gauze, or, when the intestine can be with- drawn from the belly, is thoroughly flushed away in addition to wiping. Strong germicides are not to be used, as this might lead to poisoning, and the main reliance is to be placed here too upon mechanical instead of chemical processes of cleansing. Similar are the measures of cleansing employed about the rectum and anu><. Thorough evacuation, if possible, done lioth by laxatives and by enemata, is to precede all important rectal oj)erations. M'iiere tight strictui'e prevents a thorough emptying of the gut, inguinal colotomy must o])en the way to thorough purgation. Immediately precetling the operation a large sponge attached to a stout thread is thrust high up into the bowel, the distal part of which is now well swabbed and douched either with Thiersch's solution or with plain boiled water. Where a rectal or anal wound cannot be closed by suture the iodo- form pack will render most valuable service in protecting the raw sur- faces against infectious contact with fseces and urine. The genito-urinary tract is very often infected by uncleanly catheters and bougies, the care and management of which demand some con- sideration. Urine secreted by healthy kidneys and as contained in the healtliy l)ladder is always free from micro-organisms of any kind (Cazeneuvc and Livon). On the other hand, the decomposition of urine, with the sub- sequent inflammation of the mucous lining of the bladder, is always the REGIONAL TECHNIQUE. 725 direct consequence of tlie iiitrodiiction of certain microbes into the vis- cus, either from above — that is, from tiie Ivithieys — or, much more com- monly, from behjw and witiiout — tiiat is, tlirongh tiie urethra by un- ck'unly instrumentation.

All of the organisms causing cystitis are anaerobic ; hence they are not identical witii the germs that induce the decomposition of voided urine. Fortunately, the introductiijn of septic germs into the healthy blad- der is not always and necessarily followed by cystitis. Ordinarily, a moderate amount of noxious germs accidentally intrixhiced in the blad- der will be prom])tly removed with the urine. Infection will take place much more readily where morbid conditions — as, for instance, stone or a tumor — are jiresent ; and these are the very instances in which instru- mentation of the bladder is demanded. On the other hand, it nuist be clearly stated that, both according to the experience of practice and according to the results of ex|)crinK'nt (Schnitzlcr), the simple introduc- tion of pathogenetic germs into a jterfectly normal l)ladder may be fol- Io\\ed by very virulent cystitis. Therefore we are morally Ijound to exercise the utmost care and cleanliness where catheterism of the healthy bladder becomes necessary, as, for instance, immediately following rectal operations. Bou'/ies (infl citllictcrx mav be made of metal, of flexible or hard rub- l)er, and, finally, of a fiexii)le material consisting of a wel)bed textile groundwork satiu'ated with a giuinny substance. As all of these instru- ments need lubrication, and as the lubricants most commonly employed are fats or oils, the coating of the surfaces of the instrument with fat will render disinfection by simple rinsing with or st)aking in a germicidal .solution absolutely worthless. Metal iiixtnimciifK will readily lend themselves to the most simple and most reliable mode of disinfection — tliat is, that by heat. Either b(jil- ing in plain water or soda solution, or passing the instrument through a gas or alcohol Hame or through the bed of glowing coals in a stove or grate, will certainly destroy all organic life contained in the hollows or upon the surface of metal catheters. Where constantly needed they can be safely preserved in glycerin or alcohol, but nuist be thoroughly flushed and wiped after each use. Twice a week they ought to be boiled. More difficult is the management of soft-rubber or N&laton catheters. They can be thoroughly sterilized bi/ immersion for fifteen minutes in a 1 per cent, irnteri/ solution of soda just below the boiling-jjoint without injury to their cohesion ami flexibility ; but this jirocess, re])eated too often, will finally make them hard and brittle. After a first disinfection by heat it is best to kec]i them jiermanently sus])cnded in a tall specimen- jar filled with either a 5 per cent, solution of carbolic acid or a 1 : 1000 solution of corrosive sublimate frequently renewed. Before use, adherent traces of these solutions must be first removed by rinsing and flushing with boiled water, as the urethral uuicous membrane is easily irritated ' Dk Bldfcnentzundimy, etc, Berlin, 1S90. - "Zur Aetiologie der acuten t'ystitis," Centralbl.

After use all traces of iii'iiic iiiiist be M'ashed away before the instrument is returned to its reee])taeie. Still more dittieult is the cleansinj;- and suitable ])reservation o^ v ebbed f/um bou(/ics and catheters. They will stand neither heat nor prolonjjjcd soaking in antiseptic solutions, and, being very useful and the better grades rather expensive, a practical method for their safe management is of the utmost importance. Schinnuelbusch ' has demonstrated that bri.skly-e.reeuteel friction of a webbed gum catheter or liougie during one minute with a wet compress or towel, followed by energetic ruhliing with a dry sterile cloth — as, for instance, a freshly-laundried towel — iri/l tlioroiighly dimnfect j7.« .mrface, even if it was previously smeared with and soaked in fojtid jjus. How to sterilize the hollow interior of these webbed catheters was unsolved until L. Farkas of Budapest constructed a small poi'table steam-boiler with safety-valve and conical nozzle, upon which is slipped the base of the rubber or gum catheter to be disinfected. Steam is Fig. 198. CatlH'Ur >lri ilizt-r of Farkas. gotten up in a few minutes over a gas or alcohol flame, and is made to escape through the hollow of the catheter without injury to its quality. The lubricant employed in catheterism also needs attention, as it may be the carrier of infection. Glycerin is preferable to fats. Both glycerin and fats or oils siiould be boiled before use. It is best to preserve them in metal cans or collapsible tubes that permit the escape of a small quantity only, just sufficient for one lubrication. Machine- oil cans, or for vaseline paint-tubes, will ensure against contamination of the bulk of their contents. If is h((d. practice to dip the instrument into the bottle or can filled irilli the lubricant. Finally, before doing catheterism, it is important to consider the con- dition of the urethra, which, according to Lustgarten and INIannaberg,^ regularly harbors, even in its normal state, a variety of micro-organisms, ' Anieitung zur asepi.

With, antiscjitic precautions exploratory opera- tions may now be safely made for the purpose of accurate diagnosis. Prognosis. — The prognosis is an estimate of the results which will follow any operation. It must dejiend primarily upon the knowledge obtained in the diagnosis, and secondarily upon that larger inquiry which seeks to discover tendencies and conditions alfecting the ultimate issue of diseases and operative procedures undertaken for their cure. Due weight must be given to the steady imj)rovements in the details of the treatment of wounds and the constant enlargement of the field of operations. The mortality of ordinary operations has been surprisingly reduced by the em|)loyment of means of jircventing sujipuration, while the range of ope- rations is daily and rapidly increasing. The following facts are always Avorthy of consideration, whatever may be the ojieration : 1. The native bears operations better than the immigrant. 2. The sex which has the greatest endurance is the female. 3. The age is not in itself a barrier to any necessary operation ;' however, with it we connect the most regular average diiference in capacity to bear operations ; the most favorable period is between five and fifteen ; tlie next, between fifteen and thirty ; after thirty the risk to life is more tlian twice as great as it was at the same period after birth. Young and healthy children are in danger through shock, aggravated by pain, Init bear very well the loss of blood and are little liable to pysemia after wounds. Old persons are likely to have organic diseases and degeneracies, and feeble circulation, inducing congestions, due to the sinking of the blood in the lungs, liver, intestines, and other dependent parts; are liable to die of shock or mere exhaus- tion, and do not bear losses of blood, lowering of temperature, or want of food ; they convalesce slowly, or after partial recovery fade, waste, and die ; but the thin, dry, tough, clear-voiced, and bright-eyed, with good stomach and strong will, nniscular and active, bear very well all but the largest operations. Constitutional diseases greatly modify the prognosis. In general they influence operations as follows : Scrofula gives a considerable mortality ;' generally its ill eifects are seen chiefly in the imperfect healing of ' Paget. ' OPERATIVE SURGERY. 731 wounds, the swollen cellular tissues, the thin anil lowly-organized cica- trix, or indolent ulcers :uid siiuises ; in the large majority of chronic cases the removal of a scrofulous part is followed l)y impixived health, but the ])atient remains scrofulous, and, if old, may uot bear confinement well. Syphilis is liable to delay reparative action, and the operation in those who have tertiary sores may be followed by renewed tertiary symptoms ; rheumatism and gout ]iredispose to structural clianges of arteries and kid- neys and to organic disease of the heart ; cancer contraindicates ope- rations only in its later stages, when th(> general health is failing ; an;emia is not a bad condition in which to operate ; wounds heal slowly and soundly, but if erysipelas or like casualties supervene patients are less likely to recover. Habits and temperament' should also l)e duly considered; intem- perance increases the dangers of operations in ])ro])ortion as it is habitual ; slight intemperance is much worse than occasional great excesses; avoid oj)erating on confirmed drunkards, unless compelled by the necessity of the case ; operations are hazardous on all persons who require stimu- lants before tliey eat or work ; over-eating is closely allied to intem- perance in increasing the dangers of operations, especially if the over- eating is of meat and other nitrogenous foods ; the over-fat are a bad class when their fatness is not hereditary, but due to over-eating, soaking, indo- lence, and defective excretions, their pendulous bellies indicating omental fat and deficient portal circulation ; persons in whom the vital processes are M'cak, lint without morbid action, repair wounds feebly, and are espe- cially liable to diseases of the blood and tissues, and operations u])on such persons should be deferred, if practical)le, to some ])eriod of l)t'tter health, for fear of Im'al f:iilui-e, rather than of incurring any unusual risk of life : allied to this class are the cold-blooded, with cold, damp hands and feet, dusky appearance of vascular parts, feeble circulation, small pidse, slow digestion, constipation ; nervous persons, who are exceedingly mobile and excitable, whether in their sensitive or motor organs, their whole cereI)ro- spinal system being altogether too alert and vivacious, pass through the conse(|uences of ojterations with as great imjtnnity as any other class ; malarial affections do not contraindieate operations, but in the course of con\'alescence ague fits, resembling those which precede pyaemia, may occur. Deranged or diseased conditions' of many organs variously affect the results of operations. Of the digestive organs, gastric dyspepsia is followed only by flatulence, unless vomiting is a symptom, when anaes- thetics are liable to excite cmesis, with dangerous prostration ; great caution is required with those whose biliary secretions are habitually unliealtiiy, or who have been often jaundiced, or who have a sallow, dusky complexion, dry skin, dilated small blood-vessels of the face, sal- low and l)loodshot coirjunctivtc — symptoms which indicate deranged func- tions and aixlominal plcth'ira ; eidargemcnt of the liver, wiictiier amyloid or fatty, is often coincident with chronic diseases of the bones in children, and tends to cause dcatli either b}' exhaustion or secondary hemorrhage. Of the organs of circulation, affections of the heart are not serious liind- rances to recovery from operations ; shock and loss of blood are attended with more than ordinary risk in jiersons whose hearts are feeble or embar- rassed i)y valvular obstruction, but a rapid or irregular pulse, witliout ' Paget. 732 OPERATIVE SURGERY.

Of the diseases of the resjiiratory organs, chronic hron- cliitis and empliysema, especially in old jteopie, render operations ex- tremely hazardous, owing to imperfect respiration, cough, and loss of slec]) ; ])htliisis, wlieii progressive, adds greatly to tiie dangers of ope- rations from the consequent fever, loss of food, and pain, hut, when chronic, operations are advisable which relieve the system of jiainful and wasting local diseases ; persons suffering from long-standing strumous affections, with the appearance only of tui)ereular disease, may be greatly benefited by the removal of the diseased ])art ; menstruation and pregnancy are conditions rendering operations uudesiral)le. Various other affections ' often motlify the prognosis as foUoM's : Severe operations during the stage of shock after injuries and during the period of acute inflammation, with high temjierature, are dangerous ; sjireading erysi])elas, cellulitis, and gangrene add so nnich to the dangers of severe operations tliat the chances of life are best when only the ordinary treat- ment is followed : avoid operations in acute ])y;enua when there are rigors once or more in a few days, and profuse sweatings, with very rapid pulse and breathing, and with delirium and rai)id wasting, or with dry tongue and yellowness of skin, or any considerable number of these symptoms; but an operation is justifialile in chronic jtysemia when there are wasting and sweating, \vitli tiu' formation of al^scesses here and there, and tlie injured ])art is manifestly useless and a source of irritation or of exiiaustion ; crouji does not contraindicate tracheotomy, nor peritonitis herniotomy, \v'hich are operations of necessity, and are not materially affected by the general acuteness of the existing affections. Of the dis- eases of the kidn(y, those associated with the constant presence of albu- min in the urine predispose ojxTatcd patients to erysij)c]as and jiyelitis. Decision as to Operation. — The (pie.stion of an operation enters as a new and most important element in the ease, and always demands the mo.st serious consideration, for cutting operations must be regarded as injuries, inflicted at the will of the surgeon, \\hich may destroy a person enjoying comparatively good health, or fatallv aggravate other but not serious affec- tions. The question of operation may l>e involved in doubt and uncer- tainty, re((uiring for its projx'r solution a nice a]»])reciation of pathological conditions, operative procedures, and reparati\-e processes. Surgeons may honestly differ in their views as to whether an operation would ]iroduce a cure, or be of some benefit although not a radical cure, or whctlier the benefit would justify the operation, or, finally, whether the operation could l)c ])erformed at all without destruction of life. An operation is not justifiable when the patient can be cured by any medical or other means. If the disease can be cured by a bloodless operation, as well as by one with cutting, choose the bloodless method, for the ' Paget. THE GENERAL PREPARATION FOR THE OPERATION. 733 danti'ci' is comparatively sliglit when the operation does not involve the injury of tissues. The object of the surgeon is twofold — viz. to save life and to promote comfort. He must never argue that life is not worth saving or jjrolonging. Any operation is, therefore, of undoubted pro- priety which is immediately necessary to save life, as tracheotomy in laryngeal obstructions, excision of poisoned wounds ; or when it is less severe tlian other measures, as excision of small growths, instead of em- ploying caustics; or wiien it is the only measure possible, as amputation of cruslied limbs; or the last resort, all other suitable remedies having failed, as lieruiotomy in strangulated hernia. Or, if an operation prom- ises a complete cure or long immunity from an otherwise certainly fatal malady, it is right to operate, though the procedure be severe and dan- gerous, as in the removal of cancerous growtlis. An operation is also justifiable wlien there is a reasonable jtrobability that it will promote comfort, thougli it does not eradicate the disease, as in excising a can- cerous growth. In whatever form the question of an operation is j)re- sented, all of the evidence for and against it shoukl be personally considered by the surgeon with judicial impartiality. He should never be over-persuaded by patient or friends, nor undtdy influenced by counsel, to oi)erate against convictions deliberately formed. Neither the consent, nor even re((uest, of the patient can justify such an operation. The consent of the patient, or of those resj)onsil)le for him, to the operation sliould, if jjossible, always be obtained. If he is not capable, as when intoxicated or comatose, or if he is a child and parents or guar- dian are inaccessible, operate only from clear necessity. In order that he or tliey may form a correct judgment, conununicate the decision and the reasons tiiat liave led to the conclusion ; make every necessary expla- nation as to the nature of the injury or malady, its jirolxible course and termination, and the advantages, disadvantages, and liabilities of the proj)osed operation : thus you will discharge every obligation, and remit to the patient or friends or guardian the responsibilities of a final judg- ment as to the course of procedure. As fir as practicable, the delib- erations of the ])atient and his advisers should be influenced by no other considerations than tliose presented by the surgeon. Should the decision be favorable to an O|)eration, the patient again returns to the surgeon's care and a new series of obligations is incurred. The pre])ai"ation for the operation, its manual performance, and the after-treatment present questions which will tax his knowledge, skill, and care. The General Preparation for the Operation. No ingenuity of conception or brilliancy of execution of the operator can excuse the neglect .to secure, by previous preparation, every possible advantage which can in any way, however trivial, minister to success ; even a successful issue cannot justify tlie siu'geon in sul)j('eting his patient to an avoidal)le risk. He shoukl strive to make the ]irognosis less seri- ous and to assure the success of the operation. Tiiis residt lie will more certainly attain by properly prejiaring tlie ])atient, choosing the most favorable moment for the operation, adojiting the best method of })er- forming it, and a]iplying the most efficient dressing. The Preparation of the Patient. — The first care nuist be given to 734 OPERATIVE SURGERY. the patient. It is iniportaiit that every organ and the entire system he so prepared for tiie injury ahout to he intiieted tiiat the issue will be favoi'able, for the timely discovery of morbid conditions of the viscera and the use of appropriate remedies Ix'fore the operation might, in a large proportion of cases, prevent disastrous results. The efl'eets of hal)its of excessive boflily indulgence in food and stimulants may be amended in a comparatively short time ; jtrevious rest, important to the recovery of the part about to be operated upon, may be secured ; slight derangements, which are readily amenable to treatment, such as indiges- tion, constipation, diarrluea, may at once be corrected; grave affections of the kidneys, liver, heart, lungs, and nervous centres may be so im- proved or the system so protected that the o])eration will not be serious'. Even ansemic persons with feeble circulation, when suitably pre- pared by tonics, as iron, improve their condition and bear operations well, being singidarly little liable to erysipelas, pyaemia, and other dis- orders of the blood. The patient should be placed under the most favoralile hygienic conditions; jnire air, suitable exercise, Mholesome food, and undisturbed slee|) are im])ortant features in the final ])rej)ara- tion ; the morale nuist, as far as possible, be sustained by such assurances as will secure mental quietude and hopefulness as to the result of the operation : do not exaggerate its nature, but speak encouragingly of it and of its prospeeti\-e success. Finally, as a severe shock to the nervous system, produced by an exhaustive surgical operation and ]irolonged an- sesthesia, may for a time so paralyze the stomach that digestion ceases or is greatly impaired, and the food that it contains at the moment may undergo such putrefactive changes as will render it an irritant, the food taken within six hours of the operation should be quickly assimilable and in limited quantities : milk is, in general, the best food for this pur- pose, especially with children, to which may be added a small amount of whiskey ; a warm, well-seasoned, and well-cooked cup of broth or a fragrant cup of hot coffee and milk may be preferred by the adult. The Time for the Operation. — The time appointed must be so fixed as to avoid the error of omission, delay — or of commission, haste— by a careful consideration of tlie nature of the disease, the condition of the patient, and the surrounding circumstances. It must be immediate when life is threatened and the operation offers the only chance of re- covery, and should be delayed when any of the conditions enumerated would render the operation dangerous to life or abortive in its results. But not unfrequently the disease, the patient, and the circumstances combine to enable the surgeon to appoint the month, the day, and the hour. The emi)loyment of anrestheties has so diminished the fear of operations tliat the surgeon may exercise his discretion as to the propri- ety of informing the patient of the day and hour selected. The Place for the Operation. — In the selection of the place refer- ence must be had to the comfort and safety of the patient. The office of the surgeon is frequently the most convenient place, but a risk to the ]iatient may thereby be incurred, which it is better to a\-oid — namely, the liability of rendering a simple operation dangerous by the subse- quent imprudent conduct of the ]Kitient, as exposure to the elements, excitement, f\itigue, or excesses of appetite. The room in the private dwelling should be chosen for its accessibility, THE GENERAL PREPARATION FOR THE OPERATION. 735 its size, and its exposure to light at tlie liour of the ()i)eration ; tlie best liofht on a clear day for delicate operations is reflected from tlie nortliern sky. The air of the room in which an operatiou-wonnd is inllictcd should be as free as it can be made from all forms of putrefactive organ- isms ; it should not immediately communicate with water-closets and other sources of defilement, nor be occupied as a living- or audience- I'oom. The best results, after large oiierations, have been obtained when the operating-room has been first purified the preceding day, and l)oth operator and assistants have bathed and had their clothes and all the materials used about the wound thoroughly disinfected. The Selection of Instruments. — In selecting instruments care must be taken that they are of approved utility and in good condition. The surgeon cannot employ rude articles, as a butcher's knife or a carpen- ter's saw, in amputation, unless he is placed under circumstances which prevent his oi)taining suitable instruments. And he is required to employ the more recently devised instruments which liave been recom- mended by the best authorities as preferable to those formerly in use, provided they are reasonably accessible to him. They should be so constructed as to be readily made aseptic and maintained in that condi- tion. For this jjurpose the handle should be, as far as practicaljle, smooth, and made from non-absorbent material, and the setting of the blade or shatt should iiave no recesses for filth. They must be kept in good order, as dull knives, broken forceps, or imperfect saws seriously complicate operations. They must, finally, be kept in a state of scrupu- lous cleanliness, as blood and pus may convey contagion to the person next operated, and dust and filth may fiitally poison a wound. The miniu- apparatus, also, nuist be carefully selected, for an operation may be spoiled by sometliiiig tliat was tliought too trivial for care. The testti of the quality of instruments are as follows : Draw a cutting instrument from heel to point slowly across the border of the nail, and it will catch or stop at every "nick ;" draw it across the ffat of the nail, and if at any point the edge is seen to be wiry or smooth, it is soft, and must be reapplied to the hone; ])ut if it becomes serrated like a fine saw, the edge is brittle and camiot be remedied by the hone. For pointed instriunents stretch upon a test-drum (a contrivance for the piu-pose for sale by instrument-makers) a very thin piece of kid or gold- beater's skin and push the point through. If it enter smoothly and easily, the point is good ; but if a slightly crackling noise is heard, it is defective. If a lancet is tested, see-saw the edge in the opening, and if it glides over without cutting or cuts rougiily the edge is imperfect. The preservation of instruments in good condition requires carefid attention to tlie following details : Select a place always free from moist- ure and dirt fi>r tlieir safe-keeping. Polished instruments shoidd be suspended or placed in metallic cases. After being used every in- strument siiould be thoroughly cl(>aned with warm water, and perfectly dried witli cliamois or the fire before it is returned to the ease. Silver instruments tarnish when tiiev arc exjiosed to the air or are brought in contact with hard or soft rubber, caustics, or acids. To preserve the etlge and polish of instruments, the surgeon requires two or three small hemes, some fine emery-])a|)er, two or three screw-drivers, small files, rouge, crocus, or other polishing powder, chamois, antl gold-beater's or 7.36 OrERATTVE SURGERY. kid skin. C^ittinii' iiistruiiiciits sliould have their h]aflos kcjit in jH'rfcct onk'r Ijy tho judicioiis use of tlie hone. Oecasionally the blade miLst be ground by a competent workman. Blunt instruments, Avhich are designed to enter natural or other passages, should hv frequently polished with fine emery-paper, and then with rouge and chamois-skin, in order to remove every jtartiele of rust and to maintain smooth, unblemished surfaces. Saws are sjiarpened with three-corncreil files applied in the direction of the original cut of the teeth. The case of instruments which the surgeon must jjrovide depends upon the variet}' of operations which he undertakes : if limited to ti-ifiing operations, he retpiires oidy the pocket-case ; if he pei'form minor operations, he requires the minor operating-case; if he assumes every grade of operation, be must add the general operating-case. In .selecting any case the surgeon should exercise his own judgment as to the number and kind of instruments, rather than accept the list of the maker or of any other surgeon. The best assorted ease contains many instruments which the general practitioner never has occasion to use. The case which immediately contains the instruments should l)e made of metal, and should be adjustable, so that the whole or the different parts may be jilaced in boiling water. Aluminum is adapted for a small case, and rolled copper for a lai'ge case. Convalescence. — The hygienic conditions which surround a patient the subject of an operation materially affect the results. Foul air, filthy dressings, and indigestible food will thwart the best ])lanned and exe- cuted o])eration. It is therefore the duty of the surgeon to secure to the patient all the advantages which healthful conditions afford. These are largely found in the room and its various ajipointments. The room in the private dwelling best adapted for convalescence is on the secf>nd floor from the grotnid ; the exposure should be to the south, with ample window space, and with opposite or partially opposing win- dows for thorough ventilation. The size of the room is of slight import- ance, except as to convenience, compared with the provisions fV)r the out- flow of foul air and the infl(jw of fresh air. Large cubic sjiace does not secure purity of the air, and hence is of minor importance if the neces- sary amount of fresh air is sup])lieable negligence. The preparation must be adapted both to control the cinulation in the limb or part during the operation, and to permanently close the divided vessels after the o])eration. Elastic Compression. — The most perfect method of preventing loss of blood during the operation is by elastic compression, so applied as to remove the blood from the part and prevent it from re-entering the vessels. The elastic haiifhtf/i' (Fig. 200) is tlie most serviceable and convenient appliance yet devised to meet all of these important indications. While the Fio. 200. Fig. 201. (^ Elastitt banUa.ije. Elastic bandage applied. patient is Iteing brought luider the ana'sthetic apply the bandage, with uniform tightness, from tiie extremities of the toes or fingers, according to the limb about to be operated upon, to a point above the place of o])e- ration ; where the bandage ends ap]ily india-rubber tubing, well drawn out, four or five times roiiii may be fixed with a .strong- tape j)asscd under the two or three hist turns and tied firmly ; then begin with the first turn at the extremity and remove the banchige to the |)oint where it is fastened. Tlie india-rubber tubing so tlioronghly compresses all the soft parts, including the arteries, that not a drop of blood can enter the parts Ix'hnv. Even in the most muscular and obese individuals we are able thoroughly to control the su])j)ly of l)lood l)v this simple jirocess ; the limb below the tubing resembles com- pletely that of a corpse, and we may operate as on the dead sulyect. This method may be adopted in almost all operations on the extremities with more or less complete success. In extirjiatiou of tumors, tying of arteries, and in resections of smaller bones and joints the comjiressing tul)ing need not be relaxed until the dressing of the wound is completely finished. When operating upon ])arts infiltrated with purulent matters do not apply the elastic bandage, as there is danger of forcing the puru- lent matters upward through the meshes of the cellular tissue, but raise the limb and empty the vessels as completely as possible before applying the tubing. Arterial Compression. — The control of the circulation may be effected by compression of the artery which supplies the ])art. As this method, however carefully applied, }>ermits of the loss of the blood con- tained in the limb, the amount should be diminished, as far as possible, by first elevating the limb and rubbing it towai'd the heart. The fingers afford ready and aN-ailable means of arterial compression when the artery is accessible and lies upon a bone (Fig. 202). If the Fig. 202. DigitJil compression. thumb is used, it must be laid flat upon the vessel ; in either case the pressure must not be relaxed ; if the vessel slips from the grasp, it should be instantly compressed again upon the bone by the fingers or THE PREVENTION OF HEMORRHAGE. 739 thumbs, but not by grasping- tlie linil) ; the fingers are best employed in compression of the brachial, the radial, and the ulnar arteries ; the thumb in compressing the carotid, the abdominal aorta against the vertebne, the external iliac against the brim of the pelvis, the femoral against tlie pubis, or against the femur in the upper part of the thigii. The key, the ring being so ])addc(l as to make a hard mass, is used to compress deep-seated arteries, as the subclavian. The tourniquet has several modifications (Fig. 203, «, h, c), but the most important difference is in the efi'ect upon the venous circulation ; it may compress the limb only at opposite points («) or the entire limb, the pad being placed over the artery \b, c). The most useful instrument is that in common use {b). In its application it is usual Fig. 203. Fig. 204. Tourniquets.

The screw being ])laced at one side of the limb (Fig. 204), the strap should be buckled tightly and the ■screw gradually turned to the nece-ssary tightness.

Siirf,'('ut they may be reduced to three (Fig. 213, 1, 2, 3), and will be understood by the illustrations. Acupressure is seldom resorted to, as with antiseptics it has no advan- tage over the ligation, exc^ejit when the artery cannot otherwise be eon- trolled. Direct compression (Fig. -12) is made by the pin thrust through tile flaj), j)assed over tiie artery, and brought out of the integument of the opposite side in such manner as to firndy compress the mouth of the artery against the muscle upon which it lies. Acupressure by forcejjs (Allis) is an inge- nious method of com])ressing vessels when there is much oozing from surfaces : the instrument consists of two blades (Figs. 214, 215) under the command of a spring, the lower of which is a needle and designed to transfix bleeding tis- sues ; which done, the grasp of the hand is released, and compression is instantly efl'ected between the blunt blade which lies upon the surface of the bleeeling vessels and the needle which lies beneath them. Direct acupressure. Fig. 213. Different modes of niii>lying acupressure. Cauterization. — The cautery, once the only metliod of arresting bleeding after operations, is now requii-ed only when deep-seated parts are involved, or tissues to which the ligature cannot .safely be applied. 742 OPER. 1 TI VE S UR CER Y.

Ligation of Arteries. — The application of a ligature to an artery can now scarcely be considered a serious operation, for when the antiseptic Fig. 217. Paquelin'.? cautery. method is pursued suppuration does not occur, and if the proper kind of ligature is used division of the artery docs not follow, and hence there is n( I danger of secondary hemorrhage. It is now established that when an artery is cli:)sed by an aseptic ligature it is not necessary to divide the internal coat, but only to press its opposing surfaces together temporarily, to secure permanent obliteration of its canal. In this process the intima becomes covered with granulations; these unite and form a firm union; THE PREVENTION OF HEMORRHAGE. 743 also new tissue fornis around the ligature, Hive a ring of callus, strengtli- ening the point of ligation ; meantime the ligature undergoes absorption and the cure is complete. By the antiseptic operation the artery is strengthened at the seat of ligature, and there can be no danger of hem- orrhage. It should, however, be borne in mind that to secure the best results the ligature must be of an absorbable nature; for ligatures which permanently resist absorption destroy tlie continuity of the \-essel, and, instead of adding sti'ength to the perivascular cicatrix, \\eaken the vessel- walls at the seat of ligation. The in.^fndiu'nty required are a scalpel, force})s, aneurism needle, liga- ture, director, and retractin's or spatulas. Tiie connnon scalpel is best adap- ted for the dissection, and the broad extremity of the handli' can be used to advantage in separating layers of fascia and parts where the cutting edge is not desirable ; the dissecting forceps should have accurately fitting teeth, and not liable to open at the extremity when firmly closed ; a pair of small forceps may also be required. The aneurism needle is a curved blunt instrument, with an eye near the extremity and firmly fixed in a handle (Fig. 21S). When used, the extremity is gently insinuated under the vessel, and as it appears upon the oppo- site side the loop of the ligature is seized Fif- 219. with the forceps or a hook, and, one end being drawn through, it is held as the in- strument is withdrawn carrying the other end, and thus leaving the ligature under the vessel. A needle well adapted to those cases where the artery lies deeply consists of the handle and hook (Fig. 220) and the l)lunt needle with two eves (Fig. 219); the needle is fitted to the sliaft (Fig. 220) by a ^''?/|lti'ons^''P screw ; when used, the ligature is inserted into the second eye ; the needle is then passed under the artery, and as the extremity emerges upon the opposite side the hook is inserted into the first eye, and the needle is thus held until the handle is unscrewed, when it is drawn through with the ligature. It is sometimes necessary to include other tissues with the arterv, when the sharj)-pointed needle (Fig. 219) should be used. The director is used in the dissection to raise the fascia before Aneurism needle, its division ; it is Sometimes passed under the artery as a guide to the needle. Two retractors are often reciuired, with which assistants separate the sides of the wound and expose the deci)-seated parts ; jneces of fiexihle metal or wood mav be used. The aseptic cafi/iif or Ki/l:iroriii-r/iit Ihidiiirr more effectually meets the indications present than other kinds. When so applied as not to sever the tunics of the ligate'd vessel it is gradually displaced bv organized tissue which increases the resisting capacity of the vessel. It is stated that the most careful microscopical examinations have shown that catgut increases to a considerable extent the resisting capacity of an artery in forming firm connective-tissue connections with the vessel. It follows that cat- gut ligature should be ])referred, and that it is onl}- necessary to tie with sufficient force to approximate the inner surflices of the intima with a 744 OPERATIVE SVnOERY. vi('w to ensure effective j)ro\isi()nal ohiitenition, when cicatrization will follow. Fig. 220. 3b Artcry-hdok and handle for needle. The operation is a,s follows : Determine the precise location of the artery — (1) by its pulsation ; (2) by reference to anatomical jioints in the vicinity. To render tlie former dis- tinct, tile liinl) should l)c placed in a ])osition favorable to arterial cir- culation ; to render muscles and tendons most distinct, the limb should be forcibly extended at the commencement of the operation. A^^len the dissection has pnx'eeded so far as to reach the vicinity of the artery, the operator is aided in detecting its position by flexing tlie limb, so as to relax the muscles and tissues. Before the first incision is made guard against wounding supe- ficial veins. Their position is readily defined by comjiressing the parts above the point of the proposed operation. When the first incision is about to be made the skin should be rendered tense by the thumb and forefinger of the left hand ap- plied, one on either side of ves.sel, or by the fingers apjilied at the extrem- ity of the proposed incision parallel to its course : if the first metiiod is chosen, care must be taken mit to make more traction on one side than on the other. The second method answers where the skin is naturally tense and but slight traction is necessary ; make the incision directly over and parallel to the artery, through the skin only if the artery is superficial, but also through the cellular tissues if it is deep, its length varying with the depth of the vessel and the adipose tissue. Tlie incision is sometimes made in the direction of the fibres of the muscle covering the artery, as where the great pectoral overlies the axillary ; at other times it should l)e curved, so as to raise a flap. The length of the incision cannot be prescribed, but it should always be ample. Pinch up the fascia carefully with the forcejjs (Fig. 221) ; nick it M'ith the scalpel applied horizontally ; incise freely on a director introduced beneath. In dissecting amony; muscular structures enter the muscular interstices and do not wound the substance. These inter- muscular spaces are marked by deposits of fat, esjiecially toward the terminal extremity of the muscles, and hence we should commence the sep- aration of muscles as nearly as possible at their terminal extremity. If there is doubt as to the line of separation, a puncture will disclose adipose or Opening the sheath.

If the dissection is made througii the body of the muscle, the fibres separate more readilv in an inverse direction — namely, from their origin to their attachments. The muscles may be separated witli the handle of the scalpel or the tinger-nail. The larger arteries have firm sheaths, which reijuire to l)e opened by dissection ; the smaller vessels have but slight investments, and are Fig. 222. Fio. 223. Passing tlie needle: first stage. Passing the needle : second stage. readily exposed with the jioint of a director or the aneurism needle. The sheath is opened by pinching up a small jjortion with the forceps and nicking it slightly with the scalpel ; into the opening thus made intro- duce the point of the needle (Fig. 222) ; by slight movements of its point, first uiion one side and then upon the other, separate the sheath completely around the vessel to an extent sufficient to allow simply the passage of the ligature ; as the extremity of the instrument emerges on the opposite side, with the finger of the left hand or the thumb and fore- finger pressed together steady its jioint as it penetrates the last portion of the sheath. If the artery is small and very superficial, a director may be passed under and along its groove, a l)lunt needle carrying the liga- ture. If more deeply situated, the common aneurism needle (Fig. 218) or the doul)le-eye needle (Fig. 219), should be used. The point of the needle, gently moved laterally, aids materially in separating the artery fi-oni the sheath (Fig. 223). The needle should be passed from the veins ; no force should be used, lest the instrument penetrate the coats of tlie artery. The ligature should l)e ])laced at a right angle with the long axis of a vessel, and the reef-knot (Fig. 2(l!>) tied unless there are special reasons for adopting the surgeon's knot (Fig. 20S). The first knot is tightened around the vcs.sels firmly, on either side of the ligature, near the artery, with the index fingers carried to the bottom of the wound (Fig. 224). The decree of constriction varies with the size of the arteries, but it 746 OriiRATIVE SURGERY. Fig. 224. need not be so great as to rujitiirc tlie internal coats.

It ascends under the external pterygoid muscle, and enters the skull through the sjnnous foramen of the sphenoid bone ; within the skull it passes beneath the dura mater to the middle fossa, where it divides into two terminal bi'anches ; the anterior, the larger, passes upward on the great wing of the sjihenoid in a deep groove in the anterior inferior angle of the parietal bone, where it divides. This division may be ligated for intracranial hemorrhage. The artery is most accessible where it crosses tiie anterior inferior angle of the jiarietal bone. De- termine the position of the artery by the intersection of a horizontal line drawn two inches above and parallel ti) the zygoma, M'ith a vertical die an inch behind the posterior sujjerior border of the malar bone; make a crucial incision througii the skin, sis of the sterno-mastoid muscle, c, as also the splenius muscle, through the whole lengtii of the wound ; the pulsations of the artery, a, are recognized by the finger a little above the obliipie muscle, 6, and it is isolated from its veins. The posterior attriciilar artery arises in the parotid glanil nearly oppo- site the apex of the mastoid process ; it ascends to the interval between the mastoid process and external auditory meatus, where it divides. Make a vertical incision midway between the two points above given ; the pulsations of tiie artery will prove the immediate guide for its ligation. The internal carotid artery continues directly upward from the ter- mination of the common carotid, opposite the upper border of the thyroid cartilage to the carotid foramen of the temporal bone; at first it is covered onlv by the sterno-mastoid muscle, platysma myoides, and fascia ; it lies to the outer side tif the external carotid. ]\Iake the same incision as for the common trunk, its centre being one-half to three- quarters of an inch above the ui)per border of the thyroid cartilage; veins will be met with which must be a\oided or tied ; tiie descendens noni nerve runs along the artery, and the hypoglossal crosses it about one inch from its bife.rcation. First find the external carotid, and draw it inward. Pass the needle from the outer side, carefully avoiding the jugidar vein and pneumogastric ner\-e externally, the hypoglossal nerve suix'rficially, and the external carotid internally. The internal mammary artery arises from the subclavian on its lower and anterior })art, opposite the tliyrt)id axis and close to the anterior margin of the scalenus anticus ; it runs directly downward and slightly inward beliind the clavicle on the inner surface of the costal cartilages near the sternum. The internal jugular and snliclavian veins and the phrenic nerve cross the upper part ; in the chest it at first lies on the costal cartilages and intercostal muscles, covered by the pleura behind ; but lower it is covered also by the triangularis sterni muscle. It may be tied in the second, tliird, or fourth intercostal spaces. Make an incision along tile upper edge of the costal cartilage, connnencing at the sternum, in either space, slightly upward and outward, an inch and a half in length ; divide the skin, cellular tissue, pectoralis major muscle, fascia, and intercostal muscle successively ; a thin layer of cellular tissue is exposed, which conceals the ai'tery ; pass the needle cautiously from within outward. Tiie vertebral artery (Fig. 235) arises from the upper and l)ack ])art of the subclavian artery in the first part of its course, about one-third of an inch internal to the inner border of the scalenus anticus muscle, and passes directly along the spinal column to the foramen in the trans- verse process of the sixth cervical vertebra, and then ascends through tile series of foramina of the transverse jirocesses to the cavity of the cranium. Before enteriiig tiie vi'rtel)ral canal tiie artery passes l)cliind the internal jugular vein and inferior thyroid artery to the sjiine, where it lies between the scalenus anticus and longus colli, and in a line drawn from tlie posterior part of the mastoid jirocess to the junction of the internal fourth with the external three-fourths of the clavicle.

The inferior flii/roiil arferi/ (Fig. 235) is a branch of the thyroid axis ; it ascends the neck obliquely, passing behind the internal jugular, the pncumogastrie nerve, the carotid artery, and omo-hyoid muscle to the thyroid body. On the left side it lies on the oesophagus, and the thoracic duct is at first posterior, and afterward arches over it in front of the artery to the left suljclavian vein ; near tlie gland the recurrent laryngeal nerve often passes l)etwecn its terminal l)ranehcs. Make the same incis- ion as for the ligature of the common carotid (Fig. 227). When its sheath is reached, draw it outward ; the artery crosses obliquely inward opposite this point ; when the vessel is fully exposed ajiply tlie ligature as near the carotid as you can to avoid the recurrent laryngeal nerve.

The aj-illari/ (irfcri/ extends from the lower border of tlie first rib to the lower margin of the tendon of the latissimus dorsi or the inferior boundary of the axilla, in a line dividing the anterior and middle third of the axilla.

The supra-scapular artery crosses the base of the neck just above the clavicle ; the axillary vein, in front and to the inner side of the artery, is not in immediate contact with it ; the cephalic vein passes upward in the interspace between the deltoid and jieetoralis major muscles, crosses the axillary artery above the jiectoralis minor, and empties into the axillary vein ; the nerves of the brachial plexus lie behind and above ; a thoracic branch often crosses the artery, sometimes in front antl sometimes behintl it. Place the patient on his back M'ith his shoulders slightly raised, the elbow a little separated from the body, and the head inclined to the opposite side ; make an in- cision, three inches in length, thrcc-(juarters of an inch below the clavicle, and commencing about two inches outside of the sterno-cla vicular articulation, through the skin, platysma, and subcutaneous cellular tissue ; sep- arate the fibres of the pectoralis major gradually until the posterior investment of this muscle, like an aponeurosis, appears ; now depress the shoulder and tear this fascia with the point of the director ; press downward and out-\vard w ith the finger the upper border of the pectoralis minor, when the axillary vein is lirought to view ; draw this gently forward with a blunt hook, and behind it the artery is found, with the nerves of the brachial plexus still farther behind and above ; pass the needle from within outward.

At the higher jioint ])lace the hand between pronation and supination, the thumb strongly abducted so as to render prominent the extensors, and make an incision an inch in length between the tendons of the two extensors, commencing at the lower extremity of the radius and in the line of the axis of the first metacarpal bone ; makes these incisions lightly, to avoid the superficial vein of the thunil); draw the extensor ossis metacarpi pollicis, a, inward, and the extensor secundi internodii pollicis, d, outward ; expose the artery, c, and its accompanying veins, b.

The hand being held back, make a slightly curved incision on the radial side of the pisifijrm l^one, through tlie skin and adipose tissue, about three inches in length, its concavity looking inward ; the artery, o, is dee})ly seated in a groove, and the dissection should be con- tinued along the side of tlie pisiform bone until it is exposed : the latter part of the dissection will be facilitated by flexing the hand upon the forearm ; pass tiie needle beneath from within outward. The SHpcj-firial palmar arch is tiic continuation of tiie ulnar artery into the hand (Fig. 24(j). Near the lower border of the annular liga- ment tills artery turns oblicpiely outward across the palm of the hand toward tiie middle of tiie muscles of the thumb, where it inosculates with a small branch of the radial, the superficialis volse.

ARTERIES OF THE LOWER EXTREMITY. The abdominal aorta lies in front and a little to the left side of the bodies of the vertebme, having the vena cava on its right side, the sym- pathetic nerve on its left, and the left lumbar veins behind ; it divides on the lower part of the fourth lumbar vertebra at a j)oint nearly corre- sponding to the uml)ilicus ; it may be ligated about one inch above its bifurcation, between it and the origin of the mesenteric. It can be ex- posed and successfully ligated by the operation for the common iliac : the artery being separated from the vein, with the finger or a director pass the needle from right to left.

A line drawn from the posterior superior spine of the ilium to the top of the great troehanter marks the course of the artery (Fig. 249). In the oi>eration (Fig. 250) place the patient in a prone position ; make an incisiiin on the line above indicated four or iive inches long, terminating about an inch and a half from the spine ; the cut is parallel with the fii)res of the gluteus maximus, which should be separated, and the finger intnxlueed to detect the pulsations of the artery ; separate the pvriformis and gluteus medius muscles, the borders of ^v•hich cover the vessel, and isolate the artery from its veins, and pass the needle as deeply as possible, as the artery divides just after its emerg- ence. The sciatic artery escapes from the pelvis between the jivriformis and coccygeus muscles, and descends in tiie interval between tiie trochanter major and tuberosity of the iscliium. It is covered by the gluteus ma.Kimus, and is accompanied by the sciatic nerve and the vein which lies to its posterior and inner side ; the centre of a line drawn from the posterior superior spinous process of the ilium to the tuberosity of the ischium marks the point of exit of the artery from the pelvic cavity. The patient being jirone, make an incision four inches in length, the centre of wliich falls upon the jioint of emergence of the artery, as given above (Fig. 249) ; divide the skin, cellular tissue, and the fibres of the gluteus maximus ; the artery is found to the inside of the nerve, and must be carefully isolated from the vein. The internal pudic artery, the smaller of the two terminal branches of the internal iliac, ])asses out of the pelvis through the great sacro- .sciatie foramen, internal to the sciatic artery ; it again enters the pelvis through the lesser sacro-sciatic foramen, runs along the I'amus of the ischium and pubis, and divides into the arteries of the penis. {a) At the greater saero-sciatie foramen make the same iucisi(jn as in the ligature of the sciatic artery ; the pubic is found a little internal, accompanied by its veins and the pudic nerve. (Ij) In the perineum (Fig. 251) the artery may be ligated as it descends the ramus of the ischium ; draw a line from the middle of the puljcs to the internal Ijorder of the tuber ischii.

(ii) Tile common femoral artery extends from Pou])art's ligament to the origin of the dee]) femoral, about one iiu'li and a half. It is super- ficial, lieing covered by the skin, supi'rticial and deep fasciie, and lym- phatic glands ; the vein lies on its inner side, and the anterior crural nerve half an inch to its outer side ; the vessels lie in a canal formed by the parting of the two layers of the fascia lata, and are separated by this septum. Half or three-quarters of an inch below Poupart's liga- ment will be the most favorable locality for ligature (Fig. 253). The pulsation lieing recognized midway between the anterior superior spine of the ilium and the pubes, make an incision two inches in length over the artery, commenc-ing over Poupart's ligament ; divide the skin and cellular tissue ; raise the fascia on a director and expose the sheath ; open it, and examine iov the origin of the profunda and epigastric ; draw the vein in- ward and pass the needle around the artery from within outward, ligating it above the pro- funda femoris. The incision has been made parallel with Poupart's ligament. In persons of ordinary Hcsh the fold of the groin corre- .sponds exactly with Poupart's ligaineiit, but in thos(> who are very fleshy the fold is somewhat below Poupart's ligament, and should this be taken as the guide to the commencement of the incision, there would lie danger of applying tlie ligature just below tile origin of the profunda ; it is advisalilc to bring the ligament into view before the ligature is applied, and to pass the needle a finger's breadth below.

The Resection op Bones. Resection of a bone, in part or wiiolc, is required after injuries which have destroyed its vitality, or after diseases which have resulted in caries or necrosis, or in the removal of tumors ; but the oi)eration is justifiable only when it is evident that resection is preferable to every othei" remedial measure. When inidertaken it must be so planned and executed as to become tiie first step in a process of repair by which 774 OPERATIVE SURGERY. a part that would otherwise have been sacrificed is restored to more or less cdinplete nsefiihiess. Tiie operation must be determined by the cimdition of tlie ]iatient and of tlie diseased part. As a rule the opera- tion is indicated only wlien the fryneral hcaltli admits, for if the patient is suti'ering from a progressively wasting disease, as tuberculosis or marasmus, which will necessarily prove fatal, resection would be unwise, as repair would not follow. In injuries, as gunshot, only such frag- ments of bone should be removed as are nearly or fpiite detached from the periosteum. In caries of a hollow bone the ulcer may be tlioroughly cleaned out witli the gouge and the cavity be allowed to close by gran- ulation, but if the bone is small extirpation may be necessary to arrest the process at once. If a hollow bone is affected throughout, as with periostitis, external and internal caries, or partial internal and external necrosis, extirpation of the entire bone may be required as the only alternative of amputation. Tumors of bone, if not malignant, must be removed from their locality, but if malignant, extirpation of the bone or wide resection is necessary. Resection of a joint is necessary for such shot injuries as the commi- nution of the ends of the bones, or tlie impaction of a ball in the end of tlie bone in such manner that it cannot be removed without destruction of the bone ; in compound dislocation with extensive injury of the soft parts, or complicated with fracture, and in caries which has destroyed the articular surface and continues to progress in spite of well-directed efforts to control it. Compound dislocations and fractures involving joints, once so fatal from inflannnation, do not now always necessitate excision, for when antiseptic methods are rigidly enforced from the first suppuration does not occur. Tlie fimc of operating after an injury, as a gunshot, should, if pos- sible, be within twenty-four hours of the accident, or primary ; if it is delayed beyond this period, it sliould not be performed until the inter- mediary stage of inflammation is passed. If the bone is necrosed, the rule should be not to attempt removal laefore complete, or nearly com- pleted, detachment, because the dead bone can rarely be taken out with- out removing healthy and newly-formed bone, and the new bone is not firm enough before the sequestrum is detached. The ■instrimienfs required in resection and excision may be few or many, both in number and variety, according to the nature of the case.

But frequently it is quite difficult to roach tiie part, which may be more readily divided with the forceps than the saw unless the blades are curved at a considei'able angle ; in such cases a forceps curved (Figs. 271 or 272) will lie found serviceable. The bone- gnawing forceps (Figs. 273, 274), or rongeur, is indispensable in many resections, as it enables the operator to remove projecting ?arts not accessible to otlier instruments, "he saw in one of its various forms is neces- sary. Tiie chain .saw (Fig. 275) consists of a number of pieces, with movable artic- ulations, terniinatc'(l at each extremity by handles with whicii it is worked. To use this saw, one handle is removed from tiie hook, and a needle, armed with a strong thread, is attached to the end ; the needle is passed under the bone, and the saw drawn into its jwsition, with the cutting edge up- Mard, and the liandle is tiien re-attached; ihainsuw. 776 OPERATIVE SUEGERY. the operator, grasping the handles, draws the saw alternately from side to side, until the bone is divided : there is great danger of breaking this saw if it is worked carelessly; it should l)e drawn from side to side steadily, at an angle of 45° to the long axis of the bone. The sections may consist of metallic Iteads strung on a wire with handles ; such a saw will act efficiently in whatever direction it is held.

Bone drills for the introduction of the wire suture must be provided, and an osteotrite will often l)e necessary (Fig. 282).

The preparations for the operation are as follows : Cleanse the hands and nails with soap, water, and nail-brush and wash them in liichloride solution ; put the instruments in the tray and cover tiieni with carbolic- acid solution 1 : 20 ; prepare the solution of bichloride, 1 : 2000, in the irrigator, the water being hot. The parts to be operated should l)e anti- septically prepared on the preceding day, and wrapped with aseptic dressings. Bind towels, wrung out of the bichloride solution, around the limb, one above and one below the point, and spread others over all the region of tiie wound, so as to protect the hands and instruments from contact with soiled surfaces or materials. Apply the elastic bandage luiless tlie parts are infiltrated with pus. The operation is as follows : (a) In the removal of the bone the method of operating must be adapted to each particular case. In shot fractures the extirjxition of fragments must be through openings extend- ing from tiie wound ; in necrosis tiic sinuses are iiiiides for incisions : in the e.Kcision of the bone for morbid growths the incisions must l)e largely in the direction of the tumor. The incision in general should be made as nearly as possible over the bone to be removed and parallel with arteries, nerves, and muscles. The soft parts should not be destroyed, e.xcept so far as they have undergone degeneration or interfere witJi the proper closure of the wound. Injuries to lilix id- vessels and nerves lying in the track of the incision should lie scn-upulously avoided by drawing them aside; muscles and tendons siiould, if possilile, not he divided nor their attachments incised, but should be separated to the necessary extent with a blunt instrument. The bone being exposed, the operator should preserve in the wound, and, as far as possible, in its original position, the periosteum of the bone to be removed, in order to the rejirodiiction of suftlcient new bone to preserve the function of the part. The periosteum is best jireserved by first incising it to the extent of the bone to be re- moved, and then separating it with tlie periosteal knife or the end of the scalpel. Tiie periosteum being separated, the bone must be divided by cutting forceps or the saw, and each jiortion separately removed ; if the saw is used, the soft parts should lie cait'fuily protected by compresses or a spatula introduced underneath the bone. In some eases the interior of carious caiiceliatetl bones may be scooped out and the external shell be left as the basis of new bone. The scoop may be a curved chisel, the periosteal knife, or other instrument which can be applied to the inte- rior of the carious cavity. (fj) In the resection of joints the operator should aim (1) to remove all diseased structures withdtt needlessly sacrificing jiarts ; in children, espe- cially, the epiphyses of bones must be preserved with the most scrupu- lous care, to ensure their future growth ; in adults the amount of bone removed will always have regard to the future usefulness of the joint. (2) If the functions of the joint are to be preserved, as of the upper ex- tremities, the fibrous structures must be saved in their projier relations ; 780 OPERATIVE SURGERY. the periosteum must be preserved wit li tlic attacliniciits to tlic capsule; tlic muscular attaciiuieut.s must lie separateil uuinjureil or witli the bony fraaineuts (if their insertidus, to ensure tiieir future usefuluess ; the Ijones may be so sJuqx'd and placed in position as to maintain their s])ecial movements, preserving even a useful hinge-joint at tiie elljow. (3) If the joint is to be ankylosed, as tiie knee, the surfaces of the excised bones must be accurately applied and maintained to secure firm union. The bones may be maintained in apj)osition by wire, catgut, prepared silk, and by nails and metallic jiins driven through the fragments. The silver M'ire is, in general, the best material for that purpose. It should be so inserted as not to recjuire removal — viz. after being twisted, cut it off and turn the twisted ends downward between the extremities of the bones. The treatment of resection wounds should secure rest, and free- dom from irritation. Rest is obtained by a])])aratus adapted to each case; in general the immovable apparatus of plaster of Paris is most availal)le and useful. Tliough these wounds usually heal liy granula- tion, yet by carefid attention to the use of antise})tics suppuration may be entirely prevented. They are peculiarly liable to be poisoned by septic ferments from the putrefactive matters already existing in the wound. The dressings shoidd, therefore, be scru])ulously antiseptic throughout the stage preceding granulation and subsequently to such degree as will jirotect the granulations from any infectious matter which may enter or form in the wound. Irrigate the wound after the operation with bichloride solution, 1 : 2000 ; remove every particle of dead tissue ; apply drains to every recess which will retain fluids ; and close the wound with sutures to the fullest extent practicable. Ajtjily iodoform dressings covered with bandages of bichloride or earbolized gauze, and finally two or three layers of plaster-of- Paris bandages.

Resection is to he preferred to amjiutation in the greater muiiber of lesions of the upper extremities, as the princijial ftmetion involves that of mobility. The phalanges may be resected in part or whole, but the results are not always favorable, owing to the stiffness, shortening, and deformity which so often follow. The incisions should be on the side of the joints to be excised. Efforts should be made to preserve the periosteum with a view to the ]>roduetion fif new bone in the shafts of the bones that have been removed. In the after-treatment apply a splint to the palmar sur- face, and make such extension as will maintain the full length of the j)halanx. The entire phalanx is removed by an incision over the shaft of the bone on the side ; the tendons being raised, introduce the bone forceps, divide the bone, and remove the two halves sejiaratelv at their articulation. In removing the third or ungual jihalanx make on the palmar surface a doul)le T-ineision, one end Corresjxmding to the artic- ulation, the other to the extremity of tiie finger; denude the phalanx from the end toward its base, the nail remaining intact.

(c) The proximal portion of the bone is resected by a longitudinal incision over the upper extremity of the metacarpal bone ; avoid the extensor tendon, separate the soft ]iarts from the sides of the bone ; divide the bone at the rec[uisite point witli bone forceps or witli the .saw, after being isolated from the soft parts, and as far as ]>ossible from the periosteum ; seize the fragment with the forccjis ; rai.se it from its bed (Fig. 292), and disarticulate the joint with the point of the knife. {d) In complete resection the extremity of the metacarpal lione and 782 OPERATIVE SURGERY. its correspondinir cari):!!

The phalangeal joinh .should be excised by an incision along the side, sliglitly convex downward ; through a single incision the extremities of the bones may often be reached and excised by turning them outward. In the treatment make sufficient extension by means of a palmar splint to keep tlie bones apart, and l)egin jiassive flexion as soon as repair is established. The inefacarpo-jjiia/a iii/cal jointu should be excised by dorsal incisions along the margin of the extensor tendons, which must be drawn on one side ; the articular surfaces being cleared, excise them with cutting for- ceps, a fine saw, or chain saw. The treatment is the same as after ex- cision of the phalangeal joints. The irrlxt-joiiit is j)roperly limited to the articular end of the radius and the first row of earpals. But excision at the wrist includes the removal, not only of the radius and first row of carpal bones, but of a part or whole of the ends of the radius and ulna, a part or M'hole of the carpus, the proximal ends of the metacarpal bones, or all of these at once. The radio-carpal articulation is formed between the radius and triangular fibro-eartilage above and tlie scaphoid, semilunar, and cuneiform bones below ; the carpal articidations are arthroidal ; the synovial sacs are so arranged that their communications are limited : this anatomical peculiarity should be remembered in the eflbrt to remove portions of the carpus, as it is desirable not to open these cavities far- ther than is absolutely necessary ; the ligaments are dorsal, palmar, and interosseous. There are several methods of operation, but those devised by Lister, Oilier, and Boeckel are to be preferred. (a) Lister's excision of the entire M'rist consists of a series of opera- tions, each of which must be executed with scrupulous care, as follows : Break down adhesions of tendons l)y freely moving all the articulations of the hand ; commence the first incision at the middle of the dorsal aspect of the radius, A (Fig. 293) on a level with the styloid ])rocess; carry it toward the inner side of the metacarpo-phalangeal articulation of the thumb, running jiarallel in this course to the extensor secundi internodli ; on reaching the line of the radial border of the second meta- carpal bone carry it downward longitudinally half the length of the bone, the radial artery lying tiirther to tlie outer side of the limb ; detach the soft parts from the bone at the radial side of tlie incision, the knife being guided by the thumb-nail ; divide the tendon of the extensor carpi radialis longior at its insertion into the base of the second metacarpal bone, and raise it along with that of the extensor carpi radialis brevior, previously cut across, and the extensor secundi internodii, while the radial RESECTION OF BONES. 783 im^(^'' Excision of wrist: ^, Lister's radial incision; B, Lister's ulnar incision ; C, Oilier ; D, Boeekel. is thrust some'what outward ; separate the trapeziinn from the rest of the carpus by cuttiug forceps apjtlicd in tlie line M'ith the lougitudinal part of the incision ; leaving the trape- zium in position until the rest of Fi<*. 293. the carpus is taken away, dissect the soft parts on the ulnar side of the incision from tlic carpus as far as convenient, tlic hand hcing bent back to relax the extensor tendons of tiie iingers ; commence the sec- ond incision, B (Fig. 293), on the palmar surface, at least two inches above the end of the ulna, imme- diately anterior to the bone, and carry it downward between the bone and flexor carpi ulnaris, and on in a straight line as far as the middle of tlie ttfth metacarpal bone on its pahnar aspect ; raise the dorsal lip, cut tiie extensor carpi ulnaris at its insertion into the lifth metacarpal bone, and dissect it from its groove in the ulna without isolating it from the integuments ; separate the extensors of the fingers from the carpus, and divide the dorsal and internal lateral liga- ments of the wrist-joint ; leave the connections of the tendons witii tiie radius undisturbed ; now clear the anterior surface of the ulna bv cutting toward the l)one, avoiding the artery and nerve; open tlie articulation of the pisiform bone, and separate the flexor tendons from the car- pus, the hand being depressed to relax them ; clip througli the base of the process of the unciform bone with pliers, but avoid carrying the knife tartiier down the hand than the bases of the metacarpal bones ; divide the anterior ligament of the wrist-joint ; separate the carpus from the metacarpus with cutting j)liers, and extract the carpus with setpies- trum forceps through the ulnar incision, dividing any ligamentous attachments ; the articular ends of the radius and ulna may be pro- truded at the ulnar incision and excised ; divide the ulna obliquely with a small saw so as to take away the cartilage-covered rounded part over which the radius sweeps while the base of the styloid process is retained ; clear the radius sulKciently to remove the articular surface ; if the caries is slight, remove a thin slice without disturbing the tendons in their grooves on the back of the bone ; clip away the articular facet of the ulna with bone forceps applied longitudinally ; if the caries is extensive, remove freely all the diseased bone with pliers and gouge ; examine the metacarpal lioiies and excise the articular surfaces only if they are sound, and more extensively if diseased ; next seize the trapezium with strong f()rce])s, and dissect it out without cutting the tendon of the flexor carpi radialis, and excise the end of the metacarpal bone ; clip ott' the articular facet of the pisiform bone, and, if sound, leave the remainder in position ; close the radial incision firmly throughout with sutures, and also the ends of the ulnar incision, but the middle must be kei)t open by pieces of lint 784 OPERATIVE SURGERY. introduced lightly to give support to the extensor tendons and afford free escape of discharges.

(c) Oilier makes an incision, ('(Fig. 293), from an inch below the styloid }>rocess of the radius upward along the external l)order of that bone, to a sufficient extent ; a brancli of the radial nerve being pre- served, the extensor tendons of tlie thumb arc exposed and drawn aside and the insertion of the superior longus exposed. A\'ith a pcriosteotome detach the tendon of the supinator ; denude the end of the radius of the periosteum and bend the carpus forcilily inward, dislocating the head of the radius outward. After separating the fibrous attaclnncnts excise the requisite amount. Tlie end of the ulna may be reached through the same wound, or an incision along the inner border will expose it. The after-treatment must be pursued with due recognition of the fact that the new joint at the wrist is produced by an ajiproximation of the bones of the forearm and of the metacarpus, partly by shortening of the limb and partly by the growth of new bone from the divided ends ; with projjer care, perfect symmetry of the liand can always be ensured, for as tiie radius and ulna aliove and the metacarpus below are divided in parallel lines, the shrinking of the new material between them draws the hand equally upward toward the ftu'earm : the surgeon should aim to maintain flexibility of the fingers by frequently moving them, and at the same time to procure firmness of the wrist by keeping it securely fixed during the process of consolidation. These indications are met by placing the limb on Lister's splint (Fig. 294), which consists Fig. 294. Hand after excisiun ot wii^t, laid in spliiil of an obtuse-angled piece of thick cork attached to a splint, with a cross- bar of cork attached to the under surface' about the level of the knuckles ; on the splint the hand lies semi-flexed, its natural ]iosition, the fingers midway between the extremes of flexion and extension, into \\']iich it is necessary to bring them in the daily passive movements ; the thumb is to be kept from the index finger by a pad of cotton maintained between RESECTION OF BONES. 785 behind Fig. 295. them ; flexion and extension of tlie fingers slionld be commenced on the .second day whetlier inflammation has subsided or not, and continued daily, each flnger being flexed and extended to the fullest degree possible in health, care being taken that the metacarpal bone concerned is held steady ; pronation and supination must ni)t be neglected, and, as the wrist acquires flrmness, flexion and extension, adduction and abduction, should be occasionally encouraged ; jJassive motion must l)e continued until there is no longer a tendency to contract adhesions. The radius may be resected for necrosis with excellent results, the mortality being small and the usefulness of the hand and wrist being well preserved. In the after-treatment secure rest by a wire, tin, or sole-leather splint applied to the inner surface of the arm and forearm, and use iodoform dressings. (rt) The lower extremity is broad, of a quadrilateral form, ha\ing two articular surfaces, one concave, on the lower part, for articulation with the .scaphoid and semilunar bones ; the other, on the inner side, narrow and concave, to articulate with the lower end of the ulna. Make a longitudinal int'ision along the radius on its external anterior border (Fig. 2!lo), extending downward to a point opposite and a little the styloid process ; if necessary, add two terminal incisions at the extremities of the first one ; remove the periosteum, and make section of Ijone by means of the chain-saw ; isolate the lower part of the radius from its attachments at the radio-carpal articulation, without injury to the artery (a), nerves, or tendons. (b) For the middle portion make a long straight incision on the external aspect of the bone parallel with its shaft ; denude the bone, divide it at the two points selected, and raise the fragment from its bed, leav- ing the pcriosteimi. (c) The head of the radius is quite superficial on its posterior part and surrounded liy tiie orijicular ligament, which reti.ius it in the lesser sigmoid cavity of the ulna. Resect by making a straight incision on the posterior and external j)art of the arm over the bone, divide the bone cautiously, and raise it from its articulation by cutting the ligaments with the point of the knife. (r/) In excision of the entire radius make an incision along the outer surface of the radius from the styloid process ti\-en fcjr the radius. The upper extremity, inehiding the olecranon, is exsected as follows : Make a longitudinal incision, live inches in length, over the middle of the olecranon, extending three inches above and two below it, penetrat- ing to the bone ; divide the triceps tendon at its insertion toward either edge, care being taken to avoid cutting across the aponeurosis, whicli is continuous from the edges of the tendon over the muscles lying on the posterior part of the forearm and inserted into the edges of the olecra- non ; dissect up these insertions of the fascia, as well as the origins of the muscles beneath it, from the bone to the extent of nearly two inches, which allows the olecranon to be exposed, when the edges of the incision may be drawn asunder over* the condyles, broad, curved spatuliB being used for this purpose ; with the amputating saw cut through one-half the thickness of the bone ; comjjlete the section \\\i\\ a fine saw, after which separate com])letely with a chisel and mallet. The entire ulna may be removed by the following method : Rotate the limb inward from the shoulder-joint, and carry the pronation of the forearm so tar as to cause the jialm of the hand to look directly outward ; slightly flex the elbow-joint and elevate the hand ; this twisted position places the ulna ujjon the posterior and outer asjject of the forearm, and renders it more easily accessible ; the limb thus placed, the assistants maintaining the arm and fiircarm steadily, make an incision along the jiosterior and inner asjject of the idna, commencing at the lower part of its superior third and extending downward to a point over the extremity of the styloid jtrocess, make a transverse incision, about an inch long, from the loAver extremity of the first incision, detach the tendon of the extensor carpi ulnaris from its groove on the lower part of the ulna, the ulnar artery and nerve being carefully avoided ; divide the bone at the lower part of the middle third, and separate the lower and upper fragments from their articular connections as in the removal of these bones already described. The radius a\n\. ulna may be I'emoved together, and if the periosteum remains a useful limb may result. Make a straight incision the entire length of each bone on the dorsal surfaces, separate the muscles, and when the Ijone is reached raise the periosteum and detach the articidar extremities ; keep the limb well extended during the after-treatment. The elbow-joint has two motions, flexion and extension, which are limited to the locking of the coronoid and olecranon processes in the respective fossae of the humerus. The usefulness of the joint after excis- ion depends upon the perfection of the hinge- or antero-posterior motion. The extreme conditions in which it may be left are ankylosis and a flail- like or dangle-joint action. Though in both cases the limb is often very useful, yet ever}^ effort should be made to avoid such results. After- treatment has much to do with the prevention of ankylosis, but, in gen- eral, the extent of exsection determines the degree of mobility, and also the power of controlling it ; if too little is taken away, there will be more or less comjilete ankylosis, and if too much, there will be such relaxation of the muscles as to prevent their efficient action : excisions which have given the best results have been at the commencement of the condyloid projections of the humerus and at the base of the coronoid RESECTION OF BONES. 787 process of tlie ulna. The periosteum should be carefully j>rc.ser\-e(l, whatever method is adojjted. It may be established as a rule that excis- ion for injury shoidd be partial and conservative, and for disease it should be entire or limited only by the removal of the diseased boue. Wlien the disease or injury is limited, it is of doubtful propriety to inflict additional injury by section of healthy bones, for excellent results have been obtained when the joint-ends of either the upper or forearm have been removed after complete exposure of the joint and the uninjured portions of the articulation have been unmolested. In general, the longitudinal incision, by giving sufficient exposure of the joint and enabling the operator to avoid easily the transverse division of muscidar attachments, ligaments, and fibrous structures, should be preferred. The subperiosteal method gives the best results as to the usefulness of the limb, and should be performed unless the conditions recpiire the sacrifice of these tissues. Subperiosteal exsection is as follows : Make an incision, A (Fig. 296), three inches long on the posterior surface of the joint, a little internal to the middle of the olecranon, beginning about an inch above the tip of the olecranon, and extending an inch and a half or two inches above that jioint, upon the border of the ulna, and through mus- cle, tendon, and periosteum to the bone ; with the elevator raise the peri- osteum of the ulna toward the inner side, and detach the inner half of the tendon of the triceps in connection with the periosteum by means of short, parallel, longitudinal incisions; with the left tiiumb-nail draw the soft parts which cover the internal condyle and enclose the ulnar nerve toward the epicondyle, and detach them by means of curved incisions until the epicondyle is entirely uncovered ; the last incisions separate the origins of the flexor muscles and the internal lateral ligament, their con- nections with the jjeriosteum being retained ; noAV draw the outer portion of the triceps tendon outward and separate it by short incisions from the olecranon, maintaining, however, its connections with the ]>eriosteum of the outer side of the ulna, which is raised from the bone with the inser- tions of the anc(incus ; by repeated incisions along the bone loosen the fibrous capsule of the joint from the margin of the humerus, first over the trochlea, until the internal condyle appears ; detach the external lat- eral ligament and origins of tlie extensor muscles, so that all remain in connection with each otlier and the periosteum ; now forcibly flex the arm, ])rotrude the articular surfaces through the wound, and saw them off; if the idna is sawn off l)elow the coronoid process, separate the upper fasciculi of the brachialis anticus without disturbing the union t)f the tendon with the periosteum. Subperiosteal resection may be so pei- formed as to retain the origins of muscles as follows : Make parallel incisions of proper length over the external and internal condyles ; raise the soft parts from the internal condyle, separate the attachments of the flexors with lamelhq of Ijone by means of a chisel ; raise the peri- osteum on both surfaces with the elevator, and divide the lateral liga- ment ; repeat the same operation on the external condyle ; now divide the humerus above the condyles ; scjiarate the attachments of the triceps with the periosteum and laniellaj of bone ; detach the coronoid jjrocess from the ulna ; divide the extremity of the ulna and remove it. Other incisions mav be made as follows: Fig. 296, B, Oilier; Fig. 297, A, Nelaton, B, C, Hiiter. 788 OPERATIVE SURGERY. An osteoplastic operation may be jicrloinicd as follows (^1, Fig. 298) : Make an incision from the end of the external condyle across the olecra- FiG. 296. Mt'thorls of Van Lan- genbeck and Oilier.

An external incision, B, can be adopted. The humerus is generally resected in part, though it has been re- FiG. 299.

(6) Resection of the shaft requires the utmost care to avoid wounding the brachial artery, which, with the median and ulnar nerves, passes along the posterior margin of the biceps nuiscle, and the superior pro- funda arterv and museido-spiral nerve, which wind around the posterior and external jiart of the upper and middle portions of the shaft. If the u])]K'r portion of the shaft is to be removed, make a straight incision on the external part of the deltoid muscle, care being taken not to extend the incision upw'ard so as to involve the circumflex artery and nerve ; when the lower part of the shaft is excised, the incision should be along the outer border of the braehialis anticus muscle, avoiding the musculo- spiral and external cutaneous nerves ; the bone is readily exposed and removed to the required extent. (c) The upper extremity consists of the head surrounded by the cap- sular ligament, the tuberosities, and shaft. Resect thus : Make a straight incision, commencing a little above and outside of tlie coracoid process and half an inch below the clavicle, and carry it downward to the requisite extent along the deltoid muscle on the anterior part of the joint ; the bone is here quite superficial, and is most readily exposed ; the bicipital groove being found, dislodge the long head of the bicejjs muscle and draw it aside (Fig. 300, b) ; divide the tendons of the sub- FiG. 300.

If no new bone forms, the patient may have a useful arm suppoi-ted by a ball-and-socket aj>paratus from the shoulder. The in- 790 OPERATIVE SURGERY.

Remove their surfaces with a saw ; now expose the arti(!ular surfaces of the metacarjjal bones and excise them. Tlie Utrxdl hones vciay require removal singly or in groups. These operations have never been performed according to any prescribed rules, but each operator lias adapted his incisions to the exigencies of the individual operation. In many cases the hones iiave not been resected entire, but the portion of bone diseased has been removed with a gouge. Care should be taken not to involve the synovial mem- brane of adjacent articulations which do not conmiunicate with the point involved (Fig. 3()(i), and, whenever practicable the periosteum should be preserved. The as- tragalus and OS calcis require special notice. The astragalus has most important con- nections : above it articulates with the tibia, laterally with the malleoli, and t)elow with the ealcaneum by two surfaces. It is attaciied to the ealcaneum by the interosseous, pos- terior, and external ligaments, and to the scaphoid by a ligament passing from its anterior extremity. Excision may be made with slight injury to the tendons which pass over that region or by their destruction. The a,b. , d, e, distribution of synovial membranes. Fig. 307.

Excision is as follows : Make an external incision two and a half inches in length, A (Fig. 308), from the lower extremity of the tibia and anterior to the RESECTION OF BONES. r95 external malleolus, to the middle of the cuboid bone, and a second incision backward from the centre of this incision just under the mal- FiG. 308.

ISIake an internal incision two inches long, A (Fig. 308), from just below the tip of the inner malleolus, in a curved direction, along its anterior margin, forward and upward ; separate all ligaments ; seize the bone with strong forceps and withdraw it, dividing any remaining attachments. The OS calcis articulates above with the astrag- alus by two articular sm-faces having an inter- osseous ligament ; in front with the cuboid, to which it is firmly bound by four ligaments, two plantar, which are very strong, a dorsal and an interosseous. Kesection by the plantar flap (Fig. 309) gives ready access to the bone and removes the cicatrix from the plantar surface. The patient lying upon his face, make a horseshoe incision ; carry it from a little in front of the calcaneo-cuboid articulation around the heel, along tiie sides of the foot to a corresponding point on the opposite side ; dissect up the elliptic flap thus formed, the knife being carried close to the bone, and thus expose the whole under sur- face of the OS calcis ; then make a perpendicular incision about two inches in length behind tiie heel tlu'ough the tendr> Achillis, in the middle line and into the horizontal one ; detach the tendon from its insertion and dissect up the two lateral flaps, the knife being kept close to the bones, from which the soft parts are well cleared ; then carry the blade over the upper and posterior pai*t of the os calcis, Excision of the os calcis. 796 OPERATIVE SURGERY. open the articulation, divide the interosseous ligaments, and then by a few- touches with (lie ]ioint det;ieli the Ixine from its coinieetions with tiie cuboid. Faral)euf has modified this metiiod, (' (Fig. •"JOT, Treves), by making an incision from the base of the fifth metatarsal bone along the margin of the sole to a point one and a quarter inches to the inner side of the median line ; another incision, two inches long, parallel to and a little in front of the tendo Achillis, joins the first. The flaps are raised from the bone, the periosteum cut vertically and raised from the bone, <'are being tiiken not to injure the j)eronei tendons in front. By careful dissection the bone is freed from its attachment and removed. The tarsal joints generally become carious in connection with such extensive caries of the tarsal bones as necessitates the extirpation of entire bones. Single joints may be excised when the disease is limited, as the astragalo-seaphoid, a (Fig. oOG), the calcaneo-scaphoid, the cal- caneo-cuboid, h. The incision should be made over the aflected joint and curved, and the articular surfaces should be removed with a fine saw or gouge. The ankle-joint is a hinge ; the inferior extremities of the tibia and fibula united form a kind of arch which embraces transversely the superior articular surface of the astragalus so as to render lateral move- ments impossil)le when the ligaments are tense. The operation which best preserves vessels, nerves, and tendons, as well as the periosteum, is by two longitudinal incisions, one over the external and the other over the internal malleolus, and extended above and l)clow sufficiently to give free access to all of the diseased bone. All transverse incisions involving tlic vessels, nerves, and tendons should be avoided. The limb being turned on the inner side upon a firm pil- low, make an incision two or three inches long i^ (Fig. 307) on the mid- dle of the fibula down to the point of the malleolus, and sufficiently deep to divide the periosteum ; from the extremity of the malleolus continue the incision backward, around the malleolus, an inch, merely through tlie skin, so as not to injure the tendons, and yet permit of their being raised from behind the malleolus ; at the point where the bone is to be divided separate the periosteum with the raspatorium, and turn down as much as circumstances will permit ; introduce the point of the index finger or a spatula into the interosseous space to protect the soft parts during the act of sawing ; incline the saw slightly toward the joint, so that the part to be removed will be external at the point of division ; seizing the upper extremity of the fragment with very strong forceps, separate its connections with the raspatorium and knife when necessary. Now turn the foot upon the external surface, and make the same straight incision as upon the fibula, and a transverse one at its lower end, B (Fig. 308); the periosteum is more easily separated than from the fibula ; saw the til)ia in j)lace with a fine-bladed saw when the parts are unyielding from chronic inflammatory infiltration ; in recent injuries and acute sup- jiurations it may be j)ossible, after the jjcriosteum has been separated and the ligaments incised, to gradually dislocate the foot outward with the aid of the knife, and remove tlic tibia with the saw. To gain more complete access in many cases the incisions made along the centre of the malleoli may be extended laterally along the margins of the extremities of these bones. Or the same result may be attained by extending the RESECTION OF BONES. r97 Fig. 310. incisions made along the posterior margins of the tibia and fibnla around the kiwer and anterior margins of tlie niaUeoli. A convenient method of suspending the limb is as follows : Make a splint of wood or metal fitted to the anterior surface of the leg and ankle (Fig. 310), with rings inserted at three points for suspension ; in its application the splint is well padded and laid on tlie front part of the leg and tiie limb fixed in the ordinary bandage, the ankle being free (Fig. 311); or the gypsum band- age may be applied over the splint and around the leg, a layer of old flannel being first adapted to the leg, and the ankle left exposed. Fig. 311. 1 Suspension splint. Leg suspended. Osteoplastic excision of the ankle-joint (Mikulicz) (Fig. 312, ^1), is as follows : Place the patient in a prone position, and make the following incision.s down to the bone : 1st, across the sole of the foot from a point a little in front of the tubercle of tiie scaphoid to a point just l)chind the tuberosity of tlie fifth metatarsal bone; 2d, from the extrem- ities of this incision two incisions to the base of each malleolus; 3d, a transverse cut joining tlie ends of these incisions, a ; 4th, then flex the foot, divide the lateral ligaments, and open the joint from behind, separate the OS calcis and astragalus from their attachments, and remove them at the medio-tarsal articulations. Remove with the saw the extremities of the bones of the leg at the base of the malleoli, A, and the articular sur- faces of the scaphoid and cuboid. Attacli tlie incised bones of the tarsus to the cut surface of the tibia by wire, and apply the usual antiseptic dressings supported externally by gypsum bandages. The result is a talipes equinus (Fig. 312, E). The fibula may be resected in whole or in part with the best results. No formal method is to be pursued. Make a straight incision over the part, uncover the boiic, separate the periosteum, divide with a chain saw, and remove the fragments (Fig. 313). Th(! tibia is subjected to resection more frequently than any other long lione, owing to its subcutaneous situation. The results are most favorable, as new bone is readily reproduced when the periosteum is well preserved. {a) The lower extremity forms tiic uj)per and internal part of the 798 OPERA riVE SURGERY.

Resection of fibula. RESECTION OF BONES. 799 Resection by the subperiosteal method of the entire diaphysis and lower epiphysis has resulted in reproduction of the bone removed and a useful limb." Make a straight incision along the crest to the ankle-joint; saw the bone at the requisite height ; raise the bone from its periosteal bed by carefully separating the periosteum ; dislodge the tendons from their grooves, divide the ligamentous structures, and complete the resection by tletaching the bone from the articulation. (f)) The shaft of the tibia is subcutaneous on the anterior and inner part. On the posterior part it gives attachuicnt to muscles, and along its external border is attached the interosseous ligament connecting it to the fibula. The operation will depend upon the extent of the disease and the location of the sinuses if the disease is necrosis. The incision should be ah^ng the subcutaneous borders of the bone, and extend beyond the diseased portion ; the periosteum should l)e thoroughly separated from the shaft, and the bone divided with a chain-saw at either extrem- ity ; the fragment is then easily separated. (c) The upper extremity of the tibia is broad, and presents upon its ujiper surface two cup-shaped cavities for articulation \vith the condyles of the femur. The operative process is entirely subordinated to the degree, actual situation, and form of the disease, so that there may be occasion for the crucial, the elliptical, or a simple incision, and also for a variety of saws and bone-cutting instruments. When practicable, sub- periosteal resection should always be performed. The knee-joint mav be regarded as consisting of three articulations conjoined — namely, that between the patella and femur, and two others, one between each condyle of the feiuurand the tibia : the ligamentura muco- sum is an indication of the original distinctness of the synovial mem- branes of the inner and outer joint ; the crucial ligaments may be re- garded as the external and internal lateral ligaments of those two joints respectively ; each portion of the articular surface of the femur belongs either to one or other of the three component joints of the knee, and no part is common to any two of them. The knee is a hinge-joint, having free motion in but two directions ; it is sui)ported principally by the lateral, the internal, and the posterior ligaments, and in front by the jiatella and its ligamentous attachments ; it has also a capsular ligament ; the articular face of the tibia has a semilunar fibro-cartilage which deepens the articular surface for the condyles of the fcnuir. Present experience indicates that excision should be had recourse to M'henever the injury or disease is of a nature to destroy the function of the joint and to require ankylosis to render the limb useful. It is gene- rally undertaken for chronic affections which cause ulcerative processes within the joint. The antiseptic method has relieved the operation of all of its former dangers. It is no longer a question of age or sex, or even physical health, but the decision should rest entirel}' upon the deter- mination of tiie nature'of the disease and its final results ujjon the use- fulness of the limb. The following suggestions as to the extent of the excision are import- ant: The patella should not be removed, unless diseased, as it is essential to the formation of a firm, wcll-a23i)lied flaj) ; if carious, the diseased part may be removed with the gouge or forceps ; in excision of the knee- joint in children remove at first a thin slice of bone, and, in case this 800 OPERATIVE SURGERY. should not suffi(!e, with tlie gouge scrape out carefully the softened and broken-down osseous tissue, leaving tlie niucli-thinued cortical substance, with tlie periosteum, behind ; the cpi2)hyseal cartilage is often by this means laid entirely bare from the side of the Joint ; if perforated with fistulous openings, a small s|)oon must be introduced and every particle of diseased tissue removed; in very young (•hildrcn it will often even not be necessary to remove any part of the tibia with the saw, it being practicable to remove the diseased part with the spoon ; if the epiphyseal cartilage can be saved only in part, no more should be sac'rificed than is actually necessary. The method of operating will dc|icud upon the kind of joint sought to be obtained : if union of the excised bones is necessary, the U-sha|)ed incision is in general preferable to others, as it permits the removal tA' any necessary amount of bone without injuring the soft parts, and both corners of the wound are situated as low as the anatomical conditions will allow. If an attempt is made to retain motion, a lateral incision is to be preferred, wiiich admits of exseetion witii the least destruction of the ligamentous tissues of the joint. The amount of bone removed must, of course, depend npon the extent of the disease. Exsect as follows : The leg being slightly flexed on the thigh, make a curved incision, commencing at the insertion of the internal lateral ligament into the inner condyle of the femur, and, passing just below the lower extremity of the patella, terminate it at the same point on the external aspect of the joint ; the lateral incisions should not be made lower than the insertion of the lateral ligaments, to avoid division of the articular arteries ; reflect this flap upward (Fig. 314) ; remove the patella, if diseased ; if not, leave it undisturbed and divide the lateral and inter- articular ligaments ; pass a fold of antiseptic gauze through the joint, Fig. 314. Fig. 315. Excision of knee. Excision of tlie knee by tlie sawing of the tibia (Treves). and draw it firmly under the extremity of the bone to be sawn, thus completely isolating the soft parts behind ; apply the saw first to the extremity of the femur, and then to the articular head of the til)ia. RESECTION OF BONES. 801 The position of the saw should not deviate from a right angle to the shaft of the bones, so that when union takes place the liml) will be nearly straight (Fig. 315). The hones must be maintained in apposition by two or three silver wires, which should now be introduced into th(^ anterior part of the tibia and femur, and, when sufficiently twisted, cut off and the ends turned down between the bones. To fix the bones in position use has been made of nails, wiiich are removed at the end of two or three weeks. The dressings should be antiseptic — viz. layers of iodoform gauze next to the wound, tJieii gauze Ijandagcs treated with bichloride solution, next borated cotton firmly bound by gauze bandages, and last a wire splint retained by gypsum bandages to immobilize parts above and below the knee. The knee itself should be so protected that it can be examined without disturbing tlie other dressings. The more superficial dressings should extend from tlic hip to the ankle. The limb should now be iilaccd in a sling. The dressings should not be changed, except to remove the drainase-tube, for several weeks. The wires are allowed to remain, but nails must be withdrawn after several weeks. The folloMing dressing can be readily applied : IMake a wooden con- cave splint to the calf of the leg and back of thigh, but narrow at the knee ; also, if possible, an iron rod fi>r suspension. Apply the dressing thus : Pad the posterior splint with lint or cotton-wool, and cover that part corresp(inding to the site of the wound with gutta-percha cloth or hot paraffin ; place the limb in position and carefully adjust it ; place Fig. 316. Suspension of leg. the iron rod on the front and lay folded lint between it and the limb at the groin, at the upper part of the tibia, and at the bend of the ankle ; apply an open woven roller bandage around the whole dressing from the toes upward except at the site of the wound ; over this apply the gyp- sum l)andage in two or three layers ; when tlie dressing is firm suspend tlie limb l)y the hooks; the wounds may now be dressed \vithout dis- turbing the ])art. The patcUu, though in immediate relation with the knee-joint, may be exci.sed with good results. Make a crucial incision, the transverse branch being over the base of the bone, or a second transverse incision may be made near the apex ; dissect tlie flaps off cautiously, and remove Vol. I. — 51 802 OPKRATJVE SURGERY. tlic hone or its frasjincnts ; tlic t('iivial membrane ; the articulating surface of the femur presents a little beneath its centre a pit in which the round ligament is attached ; movement is allowed in every direction, extension being limited by the anterior fibres of the capsular ligament, and flexion by the con- tact of the neck of the femur with the acetabulum. The extent of the resection should depend upon the amount of disease; if limited to the head, that part alone should be removed ; if the neck is carious, the trochanter may still be preserved ; but if the latter is involved, the bone must be divided at the trochanter minor. The methods of operating are numerous, but the single incision, with subperiosteal removal of the bone, most nearly meets the anatomical indication of the ])art. Of the several arteries distributed to this region — namely, the gluteal, sciatic, obturator, external and internal circumflex, and the superior perforating l)y anastomosis — the only one which approaches the line of this incision near enough to be incised before dividing into branches of distribution too small to give rise to' noticeable hemorrhage is a twig of the internal circumflex, which at one-eighth to one-fourth of an inch from the insertion of the obturator extermis breaks up into its terminal divisions ; this branch may be avoided by keeping the jKiint of the knife well against the bone, and dividing the tendon of the obturator externus muscle in the digital fossa.

P]very part of the wound and all sinuses must be thoi'oughly cleaned of ])articles of bone and false membrane. Or, make an incision, B (Fig. -jIT), com- mencing about three inches below the crest of the ilium, and at the same distance posterior to the antt-rior superior spine, downward to the tro- chanter major, and then along the centre of the shaft of the bone, and proceed as above. The dressings of the wound are as follows : In- troduce the drainage-tube to the bottom, then pack the wound with iodoform gauze, or close the wound ^vith sutures to the tul)e and apply iodoform-gauze pails. Enveloj) all with a wide and thick layer of borated cotton and apply the gauze bandage firmly. Place the patient on a smooth mattress and make extension at the foot with a six-pound weight. The upright position of the foot should be maintained, and the dressing shoidd be changed as seldom as possible. When completed the dressings should envelop the upper part of the thigh, the hiji, and pelvis (Fig. -319). The patient should not attempt to walk with crutches until the external wound is quite healed, which ordinarily occurs with antiseptic treatment in five or six weeks. Attempts to bear weight on the foot should not be encouraged for six months, in order to allow the fibrous struc- tures to consolidate. During the period between the healing and using the limb the hip splint (Fig. 320) should be worn. With children, extension by the application of weights and proper positions of the limb is the best means: the patient may be placed on a divided mattress, of whicli the two difterent parts are separated Fig. 320. Hip splint. RESECTION OF BONES. 805 by an interstice of several inches exactly corresponding to the spot where the excision was made. BONES OF THE TRUNK. The vertehne have been suljjected to fro(piciit partial resections. The removal of loose fragments after severe injuries, as from shot, is perfectly rational, and has resulted iu a fair measure of success. In the removal of a spinous process or arcii make a long incision above the ridge of tiie spinous process, the mickUe of wliicli is opposite the displacement ; divide all the attacliments of tiie nuiscles to the articular processes; as one end of each muscular bundle is separated from its attachment, it retracts and needs little holding back ; the saw or the nippers are gen- erally sufficient to divide the vertebral arch ; in sawing or cutting out the arch grasp the spinous process, if it l)e not broken, with a pair of stout tooth forceps, which are to be preferred to the elevator for lifting the detached bone from its natural connections ; a small crowned trephine may be used to cut through the vertebral arch, or Hey's saw. The cocri/.v may be excised in whole or part for necrosis, fracture, or for a painful aiFection, coccydynia, thus : Place the patient on the side, the thighs flexed, and the hips close to the edge of the bed ; the buttocks being separated, make an incision in the median line extending from the extremitv of the coccyx upward to the re(piisite extent ; remove the dis- eased bone either with the gouge or the drill, or the bone maybe divided with the cutting forceps. The fore finger in the rectum determines the progress and extent of the resection. The ribs are closely invested on their internal surface by the pleura, and along the groove on the lower liorder runs the intercostal artery. The only admissible primary interference when the ribs are fractured by balls is the extraction of loose fragments and the smoothing oti' of sharp- pointed ends. Resection for necrosis slK)uld be made by opening existing sinuses and carefully separating the thickened periosteum with the pleura. In the removal of morbid growths portions of ribs may require resection ; great care must be taken to separate the pleura with the periosteum with- out wounding the former. Proceed as follows : Place the patient upon the sound side, and expose the bone by an incision along tlie middle of the rib, or the incision may be curved downward : divide the intercostal muscles and disengage the intercostal artery from its groove in the in- ferior border of the bone ; separate the pleura cautiously with the handle of the scalpel or similar instrument, ami pass a thin piece of antiseptic pasteboard or other substance behind; divide the bone with the chain saw. Section of the posterior part of the ril) may be first made to avoid wounding the pleui-a ; scrape carefully each border of the bone, and do not incline the point of the knife toward the intercostal sjiace. In re- moving the false ribs support the free extremity while the rib is divided posteriorly. The costal cartilage may be removed by an incision along its centre and vertical incisions at each extremity. The stern inn has been frequently ])artially resected for shot injuries, and with verv favorable results, the mortality being very slight. When subperiosteal resection has been made for necrosis new bone has been reproduced.

In com- minuted fractures the fragments should be preserved unless quite detached, as they have great vitality and are important in the pre- servation of the contour of the jaw. For necrosis the resection should as far as possible be subperiosteal and intral)iiccal, and both objects may often be accomplished by occasionally aiding the slow pro- cess of separation of the necrotic l)one from its attaclunents to bone and periosteum with the elevator or the handle of the scalpel or a spatula. By degrees the sequestrum is loosened, new bone forms around it from the periosteum, and eventually the dead bone may be lifted from its bed with perhaps slight incisions of the gum ; liy this method large portions of the jaw, and even the entire jaw, may be rejiroduced during the process of sequestration, and not (inly its coutDur, but its function, be preserved. This method is preferable to early resection, which is liable to be followed by great contraction of the parts, even if the periosteum is preserved and new bone is produced. In resection for tumors ample external incisions are often recjuired, and large portions of tlie bone must be sacrificed. But small tumors, involving only the alveolus, may be removed with bone forceps without incision of the skin. A considerable portion of the central jiart of the jaw may be removed without incising the lip if the mucous membrane is freely divided between it and the bone and the lip is drawn well down. The wound must be disinfected with a weak bichloride solution, 1 : 5000, care being taken to prevent its entering the stomach. In closing these wounds endeavor to unite first the cut sur- faces of the mucous membrane by sutures so applied as to cause slight evei'sion of the free margins into tlie mouth. Tiien accurately close the external wound, using catgut drains, and ajiply iodoform dressings.

Or make a single curved incision along the lower margin of the jaw ; raise the periosteum from the bone to be removed ; extract a tooth opposite to each point where bone is to be sawn through ; use a small Hey's saw or the chain saw ; the bone being sawn through on both sides, divide the mus- cles attached to it as closely as possible to their insertion, carrying the knife along the concave surface (Fig. .'322). Unite the two flaps with silver-wire sutures passed through to the mucous membrane, adjusting tlie margins of the lip ; or use the hare-lip pins with tigure-of-8 suture if there is much tension ; attach the ligature holding the tongue to a fohl of adhesive strip firmly fastened. (6) The horizontal portion has the following anatomical parts to be considered : Attached on its internal surface is the mylo-hyoideus muscle, beneath which is the fossa for the submaxillary gland ; on its external surface along its lower margin is the attachment of the platysma myoides muscle, and along its alveolar margin the buccinator ; tlie facial artery mounts over its lower Ixu-der just anterior to the insertion of the mas- .seter muscle. Resect as follows : Make an incision commencing l)ehind and a little above the angle, avoiding the facial nerve and parotid duct along the border of the jaw, terminating from a (puirter to half an inch below the symphysis menti ; raise and reflect the flaj) on the face, tying botli ends of the divided facial artery ; the bone being denuded or the periosteum raised, divitle witli a chain saw passed at the proper point anteriorly, a tooth being removed if necessary ; seize the end of the frag- ment with strong forceps, and divide with the chain saw at or near the angle, as may be required ; close the wound firmly, care being taken to compress the surfaces of the incised mucous membrane closely to secure prompt union. (c) The half of fhe lower jaw has the following additional relations : The ramus terminates in two processes, one for articulation and the other to give attachment to the temporal mu.scles ; the articulation is supported by an external and internal lateral and the capsular ligament ; the stylo- maxillary ])asses from the styloid ]irocess to the angle of the jaw ; the internal maxillary artery passes behind tiie neck of the condyle in such proximity as to render care necessary to avoid wounding it in disartic- 808 OrEBATIVE SURGERY.

When the tumor is large and completely wedged in the upper part of the bone, so as to hinder the freeing of the coronoid process and prevent dislocation, cut otf the tumor as high as possible with the bone forceps or saw, and BESECTTON OF BONES. 809 then remove the remaining portion of the jaw only in case the disease is malignant. ((/) The entire lower jaw is removed as follows : Pass a ligature through the anterior part of the tongue, and trust it to an assistant; make an incision commencing opposite the left condyle downward toward the angle of the jaw, ranging at about two lines in front of tlie posterior border of the ramus, thence along the base, to terminate at tiie median line a little posterior to the most prominent part of the border of the jaw. Dissect upward the tissues of the cheek, and reflect downward, for a short distance, the lower edge of the incision ; separate the tissues forming the floor of the mouth, situated njion the inner surface of the body of the bone, from their attachments from a point near the median line as far back as the angle of tlic jaw ; next divide the attachments of the buccinator ; secure by ligature the facial artery, the submental and the sublingual ; expose the external surface of one branch of the jaw and of the temporo-maxillary articulation by dissecting the masseter upward as far as the zygomatic arch ; seize the ramus and pull the coronoid pro- cess downward Ix'low the zygoma; divide the insertion of the ptery- goideus intcrnus, grazing the bone in doing so ; carefully avoid the lingual nerve, here in close proximity ; divide the dental artery and nerve ; separate the tissues attached to the inner face of the bone as high up as a point situated about a line below the sigmoid notch, between the condyle and the coronoid process; detach the tendon of the temporal muscle by means of l)lunt curved scissors or a probe-pointed bistoury, keeping close to flie hone ; make use of the rannis, now movable, as a lever to aid in the disarticidation of the bone : to efiect safely the tlisar- ticulation of the condyle, peiietrate the joint by cutting the ligaments before backward and from without inward ; the articulation thus opens sufficiently to allow the condyle to be completely luxated ; blunt scissors may now be used to cut cai'efull}' the internal part of the capsule and the maxillary insertion of the external pterygoid muscle ; by a slow movement of rotation of the raunis upon its axis the condyle is detached and the operation completed. To effect the removal of the other half make the same incision on the opposite side, so as to meet the first on the median line ; the dis- section is similar. The aupertor maxiUa has the following important anatomical features : It is at- tached to other bones at but three princi- pal points : First, by its ascending process and articulations with the os unguis and ethmoid ; second, by the orbital border of the malar as far as the spheno-maxillarv fissure; third, by the ' articulation of the two maxillaiy bones with each other and the palate-bone ; there is a fourth point of contact behind with the ptery- goid process and the palate-bone, wliich yields easily by simple depres- sion of the maxillary bone into the interior of the month : in attacking these different points no large vessel is injui-ed ; the trunk of the internal maxillary artery may be easily avoided, or in any case tied after the Fig. 324.

Resection of the bone is performed for tiie extirpation of malignant growtLs and to gain access to naso-])iiarvngeal tumors : in the former case it is ju.stifial)lc only wiiere the disea.se is limited to the upper jaw and its corresponding palate-bone, owing to the certainty of recurrence if the disease extends beyond. The methods of procedun; are numerous, and give great and desirable latitude to the operator. Early operators cut boldly through the clieck, 1 (h'ig. o'-i-l), but to avoid unsightly .scar.s the rule now obtains of making the inci.sion in the cour.se of natural folds of the skin, 2 and 4 (Fig. 324). Subperiosteal resection may be made by these incisions, but a more formal operation is made by fol- lowing the line 1 (Fig. 324). Resect the superior maxilla below the floor of tlie orliit by the following operation (Guerin) : Make an incision .slightly convex back- ward, conmiencing at the ala of the no.se and terminating at the cor- responding connnissure of the lip, following the naso-labial fold or fur- row, 4 (Fig. 324); dissect up the two fla])s resulting from this incision until tlie nostril is exixised and the malar process isconipletcly denuded ; witli a small saw held in the right hand, saw through the malar pro- cess from above downward, and a little from within outward ; the soft palate having been detached from the posterior border of the palatine bone by a transverse incision made at the posterior border of the last great molar, and an incisor tooth having been extracted, divide the horizontal portion of the maxilla from before backward with cutting forceps, one branch being in the mouth, and the other in the nares ; make a section of the bone from the divided malar process to the nares by the forceps ; seize the bone with •strong forceps, and remove, fractur- ing the pterygoid jirocess (Fig. 325). After thorough disinfection of the wound apply iodoform dressings. The entire maxilla or portions may be resected as follows : Exti-act the incLsor teeth of that side ; divide the upper lip in tlie median line to the nostril ; continue the incision around the ala and up the side of the nose toward the inner canthus of the eye, thence continue it in a slight curve below the orbit, 2 (Fig. 324), or to the malar bone ; reflect the skin from the bone, and with a narrow saw passed into the no.stril Method of removing the resected portiou (Farabeuf). AMPVTATION. 811 divide the alveolus and hard palate ; incise the imieous menihrane of the mouth as far back as the soft palate ; cut partially also the malar process of the maxillary bone, or, if necessary, the bone itself, and the nasal pro- cess of the superior maxilla, and complete the division of these bones with the forceps ; grasp the bone with the lion forceps and detach it forcibly from the pteryyoid process and palate-bone; when the bone is loose raise the fascia t)f the orbital palate, si'parate the infra-orbital nerve, the soft palate, and any adhering tissues. The hemorrhage must be sup- pressed by ligatures and the actual cauteiy, and the wound adjusted at the lips by hare-lip pins and in other parts by carl)olized silk sutures. The KUpcvior ma.rilke may be removed at a single oju'ratinn by an incision, 3 (Fig. 324), along the centre of the nose and through the ujiper lip; additional incisions may be made, if rc(iuired, under the orbit later- ally. Or, a fonr-cornereil tlap may be made by an incision on either side from the angles of the mouth to the external angles of the eye, 1 (Fig. 324).

The Extremities. Amputation. An amputation is required only when the question of recovery by other means is negatived beyond all reasonable doubt, or when the presence of 812 OPERATIVE 8VRQERY. Fi(i. 327. an incurable disease is a source of such evil or discomfort as to render the loss of the limb desirable or beneficial to the patient. The Knal judg- ment as to the necessity of an ani])utation in any given case must be sustained bv the latest sui'uical ('\|i( liencc, for an amputation that would formerly have been justified would now be repudiated liy the best au- thorities, and the o])crator justly charged with ignorance and unskilfulness. The instruments required to form a complete amjnitating case are a long and short knife and catling (Fig. •527), metacarpal saw, scalpel, te- iiaculuin, saw, bone forceps, artery forceps, need-. Ics, t()m'ni(|uet, and elastii' bandage. The knife should be al)out twice the length of the diam- eter of the limb. The catling is a double-edged knife, the two edges being parallel until they converge to form the point ; the scalpel is large and strong, having a firm handle. The saw (Fig. 328) should have a strong back and be well set. The Ixtne forceps shotdd lie cutting. . The tourniquet should be strong (Fig. 203), I I ''"'•^ applied as in Fig. 204.

There should be six or more catch forceps (Fig. 207). The time of tlie operation must be fixed with due regard to the cause which necessitates the amputation and the condition of the jiatient. There is a time when interference nuist be avoided rather than courted, but the limits of the two periods are not always ^\'cll defined, and must be left to the judgment of the sur- geon in each individual case. In general, it may be advised, thus: (1) injuries necessitate inunediatc amputations, but the ojx'ration should not be performed during the period of reaction from shock ; (2) if the disease is acute, avoid the period of active inflammation and rapidly-spreading gangrene ; (3) in chronic affections the surgeon should regulate the time of operation according to the j)rinciplcs detailed. Tlie jildce of (imputation must be deter- mined with regard (1) to the safety of the ])atient, and (2) to the serviceableness of the resulting limb. Divisions of amputations based on the place of operation — namely, (1) in the continuity of the shaft; (2) in the con- V)ones — are now comparatively unimportant, as experience proves that both for safety to the patient and servicealileness of stump no distinction should be made between amputation in the con- tinuity and contiguity, with the exception of the ankle.

In the lower extremity the same rule applies to the wound, but as the stump is to be used in locomotion, it rc(|uires breadth and firmness to sustain con- tact witli the artificial appliances used in jtrojiression, and hence a place of amputation must be selected which will secure tlu'sc conditions. TJiis place is not always the farthest point from the trunk at wliich an am2)u- tation could be performed in a given case. But in practice it is not difficult to harmonize the two indications : when the amputation nearer the trunk would give the better stump, the danger of the wound is not Fig. 328. ■^ ^v^■^^v.^^vwvAWvw^^vw^AvAVW>AAA^A^^^v/AV.^^A^J^^^/A^^Av .Amputating saw. SO much greater, generally, as to forbid accepting the sliglitly increased risk for the lifelong ail vantage gained. Tlie immediate pvepumfion for an amputation should include all of the appliances necessary to render the wound entirely aseptic, as fully stated in the section giving the details of an antiseptic operation. The limb to be amj)utated shoulil l)e scrupulously cleansed, disinfected, and shaved as directed on the day preceding tiie operation. When other preparations are comjjlete, apply the elastic liandage from the extremity to a point sufficiently above the place of the division of the bone to pi'event its interfering with the formation of the flaps (Fig. 329). Fig. 329. Elastic bandage in amputation at the knee-joint. Tlie method of operation should aim to secure a well-nourished cover- ing of the stump, neither scant}' nor redundant, and freely movable cicatricial tissue. To obtain such results, (1) the soft parts must be very nicely adapted to the surface to be covered and well supjilied with blood- vessels ; (2) the cut surface of bone must l)e immediately covered by tlie pericsteum or the deep fascia of the part, iu order to pre\-cnt the super- 814 OPERATIVE SUROEBY. ficial fiiscia and intfwtiniciit from hccominfi; too firmly attaflicd liy the cicatricial tissue to tiic cirI of the hone. Tliese resiihs are secured hy raisiufi' tlie periosteum with the soft tissues and applying it to the cut end of the bone. The objection to the periosteal covering of the bone that osteophytes are liable to form on the extremity and render the stump tender are trivial wlien C()m])ared with the advantages which fol- low the protection wliieii it affords from necrosis and osteomyelitis, and the l)asis which it forms for a moval)lc covering. If osteoi)hytcs become tronblesome, they may readily be removed bj' a slight operation. It also freipiently happens that the mutilation of parts by the injury is so great that the surgeon can form the coverings of the stump by no fixed rules, but must exercise his ingenuity in ])atchwork. If the conditions essen- tial to a sound and useful stump are constantly kcj)t in view, any of the stereotyped or extemporized methods may, with ])atience and dexterity, be made to yield good results. The recognized methods of amputation are: (1) the circular ; (2) the single flap ; (3) the double flap ; (4) the rectangular flap ; (5) the bilateral flap ; (0) the periosteal flap. The circular operation can be executed more quickly by the following than by the ordinary method : Stand u])ou the right side of the limb, the left foot thrown forward and placed fii'mly upon tiie floor, the right knee bending sutticiently to give freedom of motion to the body; grasp the limb above the jioint of operation with the left hand, and take the handle of the knife l)etwecn the thumb and fore and second fingers of the right hand, lightly supported by the other fingers; stoojiing suffi- ciently to allow the right arm to encircle the limb readily, carry the knife around until the blade is nearly perpendicular to tiie long axis of the limb on the side next to you with the point downward and the hand above the limb. Commence the cut \\\{\\ the heel of the knife, giving slightly sawing motions, and bring the hand under the limb, and then directly njiward upon the side next to you, until the heej touches the point of commencement ; the handle of the knife held thus delicately will change its relative positions as it passes around the linili without the slightest embarrassment to the operator. The ease with which the incision is completed will depend much upon whether it commences ^^•ell down upon the side of the limb next to the ojierator ; raise the skin from the first layer of muscles by dissection, and turn it upward, t\vo or three inches according to the diameter of the limb, like the cutt' of a coat. Divide the first layer of muscles at the margin of the retracted integu- ment by the cir<'ular incision, as of the skin ; raise this layer with the knife and draw it still farther upward ; divide the last layer of muscles down to the bone (Fig. 330) by the same sweep of the knife as before given. Saw the bone at the apex of the cone. The single flap, or a short anterior and long posterior flap, is performed as follows : Stand ujiou the right side of the limb ; grasp the thigh with the left hand, placing the fingers and thunii) upon ojiposite points; then apply the heel of a long amputating knife on the farther side of the limb at the ends of the fingers, and draw it in a semicircular direction over the limb to the end of the thumb; with this single sweep divide all the soft parts down the bone : Avithout entirely removing the knife withdraw it sufficiently to enter the point at the angle of the wound, and transfix the limb, passing under the bone, and emerging at the angle of the wound AMPUTATION. 815 on tlie opjjosite side ; make a flap of the requisite length from tlie poste- rior part of the tiiigli.

In amputations tiin)Ugh tlie shaft of a jihalanx tlie ])almar flap may be made by trans- fixion (Fig. 339). Make first the dorsal incision, then make a palmar flap of ample dimensions (Fig. 338, Treves). The oval method at the articulations is as follows : Grasp the finger in a prone position on its palmar and dorsal surfaces by the fingers and thumb of the left Iiand, and flex to an angle of forty-five degrees ; make an incision iialf an inch long on the dorsal aspect of the joint a quarter of an inch above it, C (Fig. 340), and carry it then across tiie palmar surface to the opposite side, tiie fingi'r iH'ing fi)rcibly extended ; tlience, the finser beintr asain flexed, tiie incision is continued upward to the dorsum ; dissect the borders of the wound from tiie head of the phalanx, enter tiie joint on its dorsal aspect, divide the extensor tendons and lateral lig- aments, increase the flexion, wath an eft"ort to luxate the joint, which renders tlie flexor tendons easy of division. The oval amputation, D (Fig. 340, Treves), wiiieli is designed to ])lace tlie cicatrix beyond pressure, is useful (Faralieuf ). A single finger may be removed at the metacarpo-phalangeal articula- tion by the oval method (Fig. 340, Treves). A single finger and its meta- carpal hone may be removed by ex- tending tlie preceding incision (Fig. 340, Treves). The/our fingers nlay be removed at a single operation. The distal extremities of the metacarpal liones are not all on the same line ; those of tlie index and ring fingers are nearly on a level, while that of the middle finger is about half a line lo\\er, and that of the little finger is ^, disartioulation by single external flap: S, ami)Utatii>n by lateral flaps ; C, disarticula- tion by oval or raoket incision; D, modified racket incisiiiii fur imlcx finger: E, circular niclhnd, w itli \i'rtii'iil limited anteriorly l)y the folds in the skin at the base of the fingers on their palmar surfaces.

The appearance of the stump is improved by sloping the projecting portion of each knuckle with cutting pliers. The results of these amputations are excellent both as regards the usefulness of the hand and its appearance (Figs. 342, 343, 344). The thumb may be amputated at its phalangeal or metacarpal articu- lation. The first is performed in the .same manner as that of the fingers, but the removal at the metacarpo- phalangeal articulation reqiures a large flap, owing to the great size of the head of the metacarpal bone. Make an incision on the dorsal aspect, convex upward, the centre being a little above the joint, and the ex- tremities terminating on each side at the end of the palmar transverse fold ; extend the thumb and make a palmar convex incision, uniting the extremi- ties of the first, the centre extending midway between the transverse cuta- neous fold alluded to and tliat mark- ing the articulation of the first and second phalanges ; open the joint and. complete the disarticulation, remov- ing the sesamoid bones, D (Fig. 341, Treves). The palmar flap, applied to the end of the bone, sin mid accu- rately fit the curved incision above. Or the flap may be made by trans- fixion (Fig. 346). Tlie appearance of the hand after amputation of the thumb is good ; the power of grasping is lost, but prehension remains. A single vietacarpal bone is re- moved by an incision on the dorsal aspect corresponding in length with the portion of the bone to be removed. Separate the soft parts cautiously from the bone, the knife being carried parallel with its long axis to avoid wounding the palmar arch ; having made, the incisions on both sides, pass the point of the knife under the bone, so as to appear at tiie opposite side, and then, by carrying it fi)rward in contact with the under surface of the bone, di.vide the soft parts at one section : if the operation is of either the third or fourth metacarpal bone, the section should be made with the bone forceps ; if of the metacarpal bone of the thumb, saw it perpendicularly to its axis ; if of the index finger, make a section obliquely from without inward, tiie hand being supine ; if of the little finger, from within outward (Fig. 347), a, the soft parts being withdrawn by the retractor, b.

Dimrticiilation of the fifth metacarpal bone may be performed by two methods : The unciform receives the fifth metacarpal lione upon a sur- face concave from behind forward ; the line of articulation, if prolonged, would fall upon the middle of the second metacarpal bone. (1) Pronate the hand and commence an incision one line above the articulation F (Fig. 345, Treves), and carry it along the dorsum to the commissure, then under the finger, along the fold of the integument, to the opposite side, and tlience back to the point of dejiarturc ; dissect the soft parts from the bone and di.sarticulate. (2) The hand being held in a state of forced pronation, commence at the carpo-metacarpal joint with a slight lateral incision, and carry it down in a straight line to the inner border of the first phalanx of the little finger until it meets the depres- sion at the base of the little finger on its palmar surface ; then continue it around the base of the finger, following this depression exactly, and, lifting the little finger, continue the incision around to its inside and upward to join the first portion about opposite to the centre of the meta- carpal bone ; detach the integuments and muscles from the bone, and divide its articular connection with the point of the bistoury in the manner already described. Disarticulation of a mdaearpal bone is as follows (Fig. 345) : Make a transverse incision, E, a little in front of the articulation, another upon the dorsum of the metacarpal bone ; the disarticulation is then readily effected.

AMPUTATION OF THE AEM. Amputation of the arm may be performed at any point, but, as a rule, as little should be sacrificed as possible. Owing to its uniform size and single central lionc any of the different methods may be applied, but the periosteum should be raised for a covering to the l)onc. There are two elliptical methods: one on the posterior and the other on the anterior face of the limb, the highest point in the former' being the olecranon, and of the latter the bend of the elbow. The former is to be AMPUTATION. 829 preferred (Fig. 362), as it furnishes an ample covering and posterior cicatrix. Tlie circular operation gives a good stump, and is as follows : Place the arm at right angles to the body ; standing on the rigiit side of the limb, make a circular incision through the integuments ; roll the flap one and a half to t\\-o inches, according to the size of the limb ; make a second incision at the margin of the retracted skin ; divide and retract the superficial muscles, and make a third incision down to tlie bone ; raise the periosteum an inch and sa\\' the bone ; the brachial artery lies on the inside, between the biceps and internal portion of the triceps muscles. The flap operation, may be single, and may be made at any point pre- senting on one surface a suflflcient amount of tissues ; two flaps of equal size are preferable generally ; they are anterior and posterior ; the arm being carried at a right angle with the body, grasp Fig. 362. with the left hand the tissues on the anterior or lateral part of the arm, and, passing the knife down to the bone, carry it over to the opposite side, and cut out a flap in length three-fourths the diameter of the limb (Fig. 363) ; insert the knife close to the Fig. 363.

Pressure upon the sutx^lavian with a key and seizing' tlie flap contain- ing the axillary artery are unsafe measures, and should be resorted to only in the absence of the proper ajjjjliances. The elastic bandage may be applied (Fig. 360) so as to render Itleeding im]X)ssil)le either from the axillary artery or smaller vessels. Pins may be employed, as fol- lows : Select two pins, sharp-])oiiit('d and cylindrical, eleven inches long and one-fourth of an inch in diameter near the lica pcctoralis major and pass transversely across upon the axillary surface of the arm to the lower margin of the tendons of the latissimus dorsi and teres major, and, while the arm is raised, be continued downward and inward to the posterior surface of tiie inferior angle of the scapula, along the groove between the vertebral border of the scapula and the mass of muscle composed of the U-xas major and the latissimus dorsi; dissect up this flap, dividing the pcc- toralis major where it is becoming tendinous, and the minor at its inser- tion into the coracoid process ; divide the brachial plexus close to the first rib, also all other connections, thus freely opening the axilla. The arm is now carried across the chest and the scapular region well exposed ; the operator takes his position on the outside of tiie extremity, and makes an incision from the outer end of the clavicular incision back- Mard directly over the spine of the scapula to the termination of tile anterior flap at the inferior angle of the scapula ; the attachments of the trapezius to the clavicle and scapula are divided, then the omo-hyoid, levator anguli scapuhe, riiomboidcus minor and ma_joi', and the serratus magnus ; sever the remaining connections while Fifi. 370. an assistant moves the limb so as to expose at- tachments. Amputations of the arm, scapula, and clavicle liave been performed for malignant diseases by extension of this method. AMPUTATION OF THE FOOT.

Mcdio-tarsal disarticulation (Chopart's) is still ap])rovcd and perfirmed by surgeons, but is much inferior in utility to Syme's amputation (Figs. 386, 387, Treves). The line of articulation, D (Fig. 370), is determined as follows : On the internal surface o? the foot, about one inch below the end of the malleolus, two ])rominences are readily recognized on the same plane : the joint is midway between them ; on the external side it is six lines behind the ju-oininence of tiie tifth metatarsal bone. The centre of the articulation is immediately in front of the iicad of the astragalus, which is made prominent by extending and abducting the foot. The line of the articulation is changed according as the foot is flexed or extended ; 840 OPERATIVE SURGERY. when it is flexed tlie articular surfaces of the astragalus and calcaneum are nearly on the same line ; when extended the calcaneum is at least three lines in front.

Retract the integument half an inch, and divide the dor.sal and plantar structures and teiido Achillis ; separate them from the lioues, great care being taken to preserve uninjured the vessels contained in the inner part of the plantar fiap ; now di.sarticulate the cuboid and scaphoid from the as- tragalus, passing the knife between tlie astragalus and os calcis, .so as to divide the interosseous ligament ; separate the .soft parts from the under surface of the os calcis wiiilo .int, and the flap should lie taken from the firmest tissues accessible. The following method (Guyon), B (Fig. 401), gives a good stump: Make an incision from the base of the exter- nal malleolus, posteriorly, around the external surface of the foot iunnediately below the malleolus, and inward toward the internal border, but curved forward to a point an inch in front of the ankle-joint (Fig. 397) ; make a similar incision on Fig. 397. the internal surface, and unite the two behind by a transverse incision having a slight con- vexity downward ; separate the soft parts from the bones, and saw the tibia and fibula at the lia.se of the malleoli about an inch above the articular sur- face.

At no other point is it more neces- sary to seciu'e a sound and u.seful stump than in this part. This is due to the incessant use. to which it must be applied and its ex]iosure to injury. But it presents intrinsic difliculties in the application of the ordinary methods of amputation. This is apparent in the development of the muscles of the calf, the tajiering form of the lower portion, and the subcutaneous position of the tibia. The circular flap cannot be re- tracted without dividing it longitutliiially ; the single jiosterior fla]) is of immense size, and is counteracted only by the integument of the anterior part of the leg; the double flap gives a great inequality of flaps; the 84G OrT:n. 1 TIVE SVRGF.R Y. single external flaj) leaves liie crest of the tibia hut slightly covered. The results of amputation of the leg have, in consequence of these con- ditions, been more unsatisfactory than at any other point. Necrosis of the tibia, conical stumps, ulcerated coverings, and tender cicatrices have been the rule when the old methods have been jtreferred. J^)Ut bilateral Haps of the soft parts and periosteal coverings of tiie tibia give a tirm, compact, and enduring stump. Tlie place of division of the bone may be at any point, but at the lower part of the leg the commencement of the calf is most favorable for a symmetrical stump, and at the upper part is to be preferred a point two inclies below the tubercle of the jiatella, which permits the knee to be bent and brings the support upon tlie condyles of the femur. An am])utation at the latter point is indicated wlienever tlie leg is permanently flexed either at a right or at an acute angle with the thigh. If the amputation must be very close to the joint, disarticulation shoidd be preferred, for the risk to the jiatient of the knee-joint amjjutation is no greater than of an am])U- tation of the extreme upj)er third of the leg, while its practical benefits are much superior, as confirmed l)y experience. The elastic l)andage siiould be first applied to a point above the knee (Fig. 329). The bilateral Haps here recommended should be made as follows: Commence an incision with a large scalpel in the centre of the anterior surface (Fig. 398), and Fio. 398. Bilateral flaps. carrj' it downward along the side of the leg so as to make a slightly curved flap with its convexity below ; after the incision has passed over the prominent ]>art of the leg toward the posterior surface, incline it slightly upward until the middle of the limb is reached, where it should be continued directly up to the point at which the bone is to be divided ; make a similar incision on the oppo.site side ; these lateral flaps should consist of the skin and superficial fascia ; dissect them upward to the extent of one inch in the leg and two inches in the thigh ; now make a circular division of the muscles to the bone with a long knife ; saw the bone or bones at tiiis point, and direct an assi.stant to seize and hold the extremity firm with strong forceps (Fig. 333) : with the perio-steal knife or the thumb-nails (which are equally efficient) raise the peri(isteum from the tibia to the point where the latter is to be cut ; divide the bone at the base of the periosteal flap. The periosteum must be cut at its attach- ments to the linea aspera of the bone, and should lie raised only from the tibia, the fibula being fir.st exsected. The covering thus prepared has the integument externally, the perio.steum internally, while the intervening tissues, muscles, vessels, nerves have not been disturlied in the dissection; the periosteal flap falls like a hood over the end of the bone, the skin- AMPUTATION.

AMPUTATION AT THE KXEE-JOINT. This amputation now ranks among the most successful operations both for safety and the usefulness of the stump ; as compared with amputa- tions through the thigh it is quicker, easier, and requires sim])l('r instru- ments, and there is less shock ; the integuments preserved are, as a ride, better adapted to sustain pressure ; there is less risk of injury to flaps from a rough-sawn bone, and less retraction of muscles ; the sustaining power is more quickly acquired ; the j^oint of support is broader and better fitted for pressure ; from large anastomoses about the joint the blo()(l-su])])ly is more quickly established. This amputation may be made by simple disarticulation, or in addition the condyles of the femur may be sawn through. If there is no disease and ample flaps can be made, the bone should not be sawn. The follow- ing opinion of an experienced mechanical surgeon (Dr. E. D. Hudson) is most instructive : " The practice of dividing the condyles cannot be sustained by any rational hypothesis nor practised on any scientific principles : except dis- ease or injury of the condyles compels their excision, their osseous cover- ing and cartilage investments should be kept inviolate from knife and saw, for, as constituted, they are the strongest, most tolerant, and import- ant supports in the entire body ; the inter-condyloid fossa is readily filled, even with the convexity of the condyles, with a neatly-shaped elastic pad of wool felt made to extend over them for a cushion in the adaj)tation of jn-othetic apparatus. Equally reprehensible is the method of placing the patella over the fossa with a view to making that a point of support, and also of sa^\ing off the condyles and applying the j)atella to the cut surface : these and other ingenious experiments are of no practical value." There are many methods of operating, but the bilateral-flaj) method, devised by the author, is to be preferred for the reasons above given ; the joint surface of the bone should not be disturbed unless diseased, and AMPUTATION. 849 the patella may be left in its ])luce, though it is of no value to the stump. The line of the articulation lies internally nine lines above the promi- nence of the tibia ; the lower border of tlie patella is on a line with the articulation, and externally it is nine lines below the prominence of the external condyle. Operate as follows : Select a large scalpel, and eonuncnce an incision about one inch below the tubercle of the tibia, and cut to the bone ; carry it downward and forward beyond the curve of the side of the leg, thence inward and backward to the middle of the leg, thence upward to the middle of the popliteal space ; repeat this incision upon tlie opposite side; raise the i\:\]>, consisting of all tlie tissues down to the bone, until the articulation is reached ; divide the lateral ligaments, enter the joint, and sever its connections internally and externally. Care should be taken that the incisions incline moderately forward, down to the curve of the side of the leg, to secure ample covering for the condyles ; the incision upon the internal aspect should have additional Fig. 403.

Osteoplaatic aiii'putation of the knee (Gritti) consists not only in remov- ing a portion of the condyles, but also of incising the patella, A (Fig. 408), anil placing the cut surface upon the sawn condyles for the purpose of securing union of the bones. Stokes modified this operation by dividing tlie bone from a half to three-quarters of an inch above the condyles, in order to secure a surface better adapted to the patella. The modified circular method (J. Lister) is as follows : First cut transversely across the front of the limb from side to side, at the level of the anterior tuberosity of the tibia, and join the horns of this incision by carrying the knife at an angle of forty -five degrees to the axis of the leg through the skin and fat ; elevate the limb, dissect up the posterior skin-flap, and then proceed to raise the ring of the integument as in a circular operation, taking due care to avoid scoring the subcutaneous tissue ; by dividing the hamstrings as soon as they are exposed, and bending the knee, the upper border of the patella is exposed; then sink the knife through the insertion of the quadriceps extensor (Fig. 405), and having cleared the bone inunediately Fig. 405.

AMPUTATION OF THIGH. The thigh is composed principally of muscular structures, which sur- round the femur in two distinct layers, the superficial and deep ; the superficial nuiscles all spring from the pelvis and go to the leg, and the lower they are cut the more they retract, and vice versd. AMPUTATION. 851 Observation and cxjierience (E. D. Hudson) teach that amputations of tlie thigh, as ordinarily pertonned and ul- Fiu. 400. timately treated with prothetic apparatus, are unnecessarily disabling; but with the bilat- eral and periosteal ilap, and as full length of the femur for leverage as the injury or disease will safely allow, a quality and ca- paeitv of stump may be obtained which, with appropriate, well-adapted apparatus, will as- sure the patient a firm basis of support on a line with the axis of the thigh. Ample lever- age and adequate motor power enable him to balance his weight exclusively on his artificial limb, and to walk without a cane with ease and gracefulness. The method of procedure ret[uires the same incision as the operation on the leg already detailed (Fig. 407). It is highly important to save all the blood possible, and for this purpose the elastic bandage should first be applied, and carried to the hip, where the elastic tourniquet is applied (Fig. 409). If the bandage is not at hand, the tourniquet may be placed loosely around the thigh, the thigh raised for a few minutes while it is rubljcd toward the hip, and then the tourniquet is tightened (Fig. 40(5). Anfcro-jjostcrior flaps are made thus : Stand- ing at the right side of the limb, grasp the soft ])arts and bring them forward ; transfix the limb, tiie knife grazing the up])er surface of the bone, and make an anterior flap (Fig. 407) ; reintroduce the knife, and, passing it under the bone, make a posterior flap longer than the anterior to com- pensate for the greater retraction ; complete the operation as in the lat- eral-flap method.

Amputation may be performed by the single flap, anterior or internal ; the double flap, lateral or antero-posterior ; the oval ; and the circular (Fig. 408). These different methods have been almost indefinitely modi- fied.

The irrfieal and ciiTitfar method (F. Jordan) is performed as follows (Fig. 410) : Alake an incision along the outer side of the thigh, extend- ing downward from tiie top of tlie trochanter for six or more inches ; enucleate the head of the femur from the acetabulum ; sejwrate the muscles and tissues ; now make a circular incision down to the bone at the requisite point ; saw the bone ; while an assistant seizes and holds firmly the lower end of the u])|ier fragment, complete the disar- ticulation. If the artery is not compressed sufficiently certainly to prevent hemorrhage, it may be tied in the flap. Double aidero-posterior flaps are made thus: The elastic bandage being in plai'c, standing on the outside of the limb, insert tlie point of a long catling about midway between the anterior superior spinous process of the ilium and trochanter majc^r, keeping it rather nearer the former than the latter ; then run it across the fore part of the neck of the bone, and push it through the skin on the opposite side about two or three in(thes from the anus ; next carry it downward and forward, so as to cut a flap from tiie anterior aspect of the tliigh about four to six inches in length. When the blade is entered the limb should be held up, and even slightly l)ent at the joint : the instrument will then pass along more readily than if all the textures were thrown on the stretch ; moreover, there is greater certainty of passing it behind the main vessels, and even dividing sonw of the Hi)res, if not the whole, of the iliacus internus and ])soas muscles. The flaj) being raised, the ])oint of the knife .siiould then be struck against the head of the bone, so as to divide the anterior part of the capsular ligament and any texture in this situation which may not have been included in the flap. To facilitate this part of the operation, the knee should be forcil)ly depressed bv the assistant who holds it; tlie head of the bone will thus be caused to start from its socket, and, if the round ligament is not ruptured by the force, a slight Furneaux Jordan's method of ampu- tation at the hip- joint. 854 OPERATIVE SURQERY. touch with the edge of the knife will cause it to give way. At this period depression being no longer reipiircd, the assistant should bring the head of the femur a little forward, to allow the knife to be slipped over and l)eliindit; it should then be carried downward and backward, so as to form a Hap somewhat longer than that in front, the last cut completing tlie separation of the limb. Thv mn(jlv-fl(tp mcfhod admits of very ra]>id ])('rf(irmance. The fol- lowing are the several steps: The patient lying u]»on the edge of the table, the hip projecting, the artery is compressed upon the horizontal branch of tiie pubis ; tiie o])erator then takes a position on the outside of the limb (the left), which is separated from the other and slightly flexed on the pelvis, and, raising the soft parts, which cover the anterior face of the limb, enters u very long doul)le-l)laded knife midway i)e- tween the great trochanter and the anterior superior sjiine of the ilium, directing it at first slightly from below upward and from without inward, so as to reach the head of the femur and open the capsule of the joint ; he now elevates the handle and carries the knife in a proper direction, the point emerging about an inch below and in front of the tuberosity of the ischium ; the knife is then carried downward along the anterior surface of the bone, and a large semilunar Haj) is made, extending nearly half the length of the thigh, or six inches: care should l)e taken that the Hap is as long on the inside as on the outside : an assistant raises the flap, at the same time compressing the artery which it contains ; the knife is now applied to the capsule, which is divided close to the acetabulum, as if about to cut across the middle of the head of the fenuir and at least half of its circumference ; the limb is then abducted to luxate the head of the bone, the knife passed l)ehind it, and the soft parts on the posterior portion of the limb divided as in the circular operation. Lateral flaps (Fig. 411) are made as follows: The patient must be laid upon his back with the tuberosities of the ischia pn jecting slightly beyond the edge of the bed and the limb held in a position lietween abduction and adduction. Then, having determined l)y anatomical rules the anterior and external side of the articulation, the operator, holding perpendicularly a long double-edged knife, introduces it at this point with its lower edge looking downward toward the great trochanter. As the point of the knife enters it should be carried around the head of the femur on its outer side, whilst its handle is inclined upward and out- ward and pushed steadily on in this direction, so that it ])erforates the integuments a few lines below the tuberosity of the ischium. While this is being done an assistant grasps the tissues over the trochanter and carries them outward in order to assist in the formation of the external fla]), and the knife is carried dowuM'ard and outward with a slightly sawing motion, around the great trochanter and along the fenuir, cutting out a flap from three to four inches in length. The first flap being thus made, the operatcn', grasping the tissues on the inside of the thigh and carrying them inward, introduces the knife below the head of the femur and in the inner side of its neck, holding it in a perpen- dicular position. As it enters the point of the knife should pass around the neck of the femur and come out at the lower angle of the wound already made, without coming in contact with the bones of the pelvis ; AMPUTATIOX. 855 it is then carried downward along the femur and avoiding the lesser trochantei", so as to make an internal flap of the same length as the external. The flaps being drawn aside by the assistants and the arteries Fig. 411. Amputation at the hip-joint by external and internal flaps (T. Bryant). tied, the surgeon grasps the femur with his left hand, and, holding the knife perpendicularly on the inner side of the head of the bone, cuts the capsular ligament without attempting to penetrate the articidation. The joint being opened, the disarticulation is concluded by cutting the fibrous and mu.scular tissues which remain. Double flapH, long anterior and short posterior, give good results (C. Heath). The surgeon inserts the point of the knife between the spine of the ilium and the trochanter major, and carries it across the thigh, as near as may be to the head and neck of the femur, until the point appears on the inside near the scrotum, which should have been previously drawn away. The knife is tt) cut slowly downward to make a flap, under which an assistant inserts his four lingers in order to be able to grasp the flap and aid in compressing the principal artery as the operator completes the flap, which should be a large one. The assistant h(jlding up the flap, the surgeon cuts the attachment of the gluteus medius muscle from the upper edge of the trochanter if it has not been already done, opens the capsular ligament of the joint, and divides the ligamcn- tum teres. The head, of the bone can then be readily withdrawn from the acetabulum. The knife, being placed behind the head of the bone and the trochanter, should be carried obliquely downward and backward so as to form a shorter flap behind than Mas made before. The bloodless amputation of Wycth is described bv him as follows : " 1. With the jiaticnt in the usual position for a hiji-joint amputation, the limb should Ix- cin]>ticd of blood either by elevatit)n of the foot and lowering of the trunk, or l)y the Esmarch bandage applied from the toes 85G OPERATIVE SURGERY. to the trunk. Under certain conditions the bandage can be only partially, or may be not at all, applied, ^\'hen a tmnor exists or when sejjtic infil- tration is present, pressure should only be exercised not quite to the dis- eased portion, for fear of driving septic matter into the vessels. After injuries attended with great destruction, crushing, or pulpification, of course tlie Esmarcli Itandage is not applicable, and one must trust to elevation to save as much blood as possible. " 2. While the member is elevated, or before the Esmarch bandage is removed, the rubber-tubing constriction is applied. "The object of this constriction — and it is the chief point in the method — /.s the absolute occlusion of every vessel ett the level of the hijj- FiG. 412. The needles and constrictor applied: circular and longitudinal incisions for skin flap. joint sf(feli/ above the field of operation, permittiur/ the clisarticulatio)i to be completed and the vessels secured before the touruiepiet is removed. "To prevent any possibility of the tourniquet slipping, I employ two large mattress-needles or skewers about three-sixteenths of an inch in diameter and ten inches long, one of which is intniduced one inch below the anterior superior spine of the ilium and slightly to tlie inner side of this prominence, and is made to traverse superficially the nmscles and fascia on the outer side of the hip, emerging on a level with, and about three inches from, the point of entrance. The point of the second needle is made to enter one inch below the level of the crotch internally to the saphenous opening, and, passing squarely through the adductors, comes out an inch below the tuber ischii. The points are at once shielded by l>its of cork to prevent injury to the hands of the operator. No vessels are endangered by these skewers. A piece of strong white- rubber tube, half an inch in diameter and long enough when tightened in position to go five or six times around the thigh, is now wound very tightly around and above the fixation needles and tied. If the Esmarch bandage has been employed, it is now removed. Lanpliear succeeded in holding the constriction in place with only one (the outer) needle. Deaver was equally successfnl in holding the tubing well up by two strips of roller bandage, one before and one behind, held by an assistant, and thus dispensing with the needles. Since the needles, are, however, AMPUTATIOy. 857 ahsolutelv safe, easy to obtain, and entirely out of tlie way, lie does not see any benelit to be derived from their disuse. On the contrary, he would beafraid to operate without them. As the pressure of the constricting rubber is considerable, they should be strong. Bristow states that ou one occasion a skewer of inferior quality gave way, and hemorrhage was narrowly averted. " 3. In tlie formation of Haps the surgeon must be guided by tlie con- dition of tlie parts within the held t>f operation. When permissil)le the following method seems ideal : About six inches below the tourniquet a circular incision is made, and this is joined by a longitudinal incision commencing at the tourniquet and passing over the trochanter major. A cuff tiiat includes the subcutaneous tissues down to the deep fascia is dissected off to near the level of tlie trochanter minor. At about the level of the trochanter minor tlie remaining soft parts, together with the vessels, are divided down to the bone by a circular cut, and, in order to facilitate the search for the vessels, the soft parts are rapidly removed from the femur for several inches below the line of the divided muscles. At this stage of the operation the larger vessels, veins as well as arteries, should be tied with good-sized catgut. Now leave the entire extremity Fifi. 41 s.

When tlie larger and easily-recognized vessels have been secured, the muscular attacliments to the u})per extremity of the 858 OPERATIVE SURGERY. bone are lifted off with scissors or knife, keeping:; along very close to the hone. Holding the soft ])arts away with retractors, the eapsnlar liga- iiU'iit is exposed and divided in its cinnunfcrence. Forcible elevation, abduction, and adduction of the thigh permit the entrance of air into the socket, and at the same time rnpture the ligamentum teres, and the disarticulation is thus easily and rapidly effected. If, now, the tourni- quet be carefully and gradually loosened, each bleeding jioint may be determined, and the force])s applied as required initil the tul)e is entirely removed. tShonld any diiKeulty be encountered in the effort at enuclea- tion (which is scarcely possible), the same precaution in securing all bleeding points sliould be exercised in removing the tourniquet, and enucleation completed with the tourniquet out of the way. "4. In the closure of the wound silkworm gut is preferred for suture material, and one good-sized rubber drain from the acetabulum out at the most dependent part of the wound. When by reason of the prox- imity of a neoplasm or the destruction of the parts by accident or disease this ideal method is not practicable, any modification may be jiractised, preference being given to the incision that keeps farthest from the tumor or gives the healthiest flaps. When there is not sufficient material for perfect closure, it is even safer to err on the side of an unclosed wound and trust to granulations or grafting for ultimate closing of the wound. When, by reason of severe hemorrhage before operation, or when from any pathologic ansemia or condition of weakness, the operation should be rapidly completed and the small amount of blood that will necessarily be lost from capillary oozing should be saved, sutures of silkworm gut should be rapidly introduced, the wound jiacked with hot sterilized, plain gauze (not iodoform or bichloride gauze), and the sutures temjtorarily tightened for snug compression of the wounded surfaces. This packing at once controls all oozing, and can be removed in from twenty-four to forty-eight hours after reaction, and tlic sutures finally secured." Accidents ■which may Occub during an Amputation. Shock, a distnrliance or paralysis of nerve-centres, is liable to supervene toward the close of an operation, especially on a sudden loss of blood, when the operator is least prepared to encounter so formidable a complication. In general, it is remarkable how little impression is produced by even the most severe operations, and hence the surprise which the discovery of the ]>resencc of shock creates. The patient often passes suddenly from a state of jn-oper anaesthesia, and without any ad- ditional ansesthetic, to a condition of more or less profound shock. There is no warning of its approach, and the first impression is that too much of the anaesthetic has been given. This is not narcosis from ana3s- thesia, but shock. The degree of jn-ostration depends somcMhat upon the previous condition of the patient and tlie nature of the disease, but more markedly upon the degree of shock from the injury wliich gave rise to the operation, the amount of blood lost, and the length of the operation. The bodily tejuperature and pulse are the best guides to de- termine the severity and danger of shock, and ought to be noted, first, before the operation, and, second, during and after the operation : vari- ations not accounted for by obvious causes will indicate the effect of the ACCWESTS WHICH MAY OCCUR DVRINO AN AMPUTATION. 859 operation, and often give timely warning of impending danger. In an average of cases of operations recoveries liave a fall of temperature of less than one dejrree, and deaths of more than three deiirees ; a fall liddw 97° F. is very critical, but recoveries exceptionally occur. When the condition of the patient or the symptoms indicate a susceptibility to shock jn-eventive measures should be adopted. One of the most simj)le and efficacious is the repeated administration of brandy or whiskey sev- eral hours preceding the operation. An ounce of whisky hypo- dermic injection or by tlie mouth or rectum ; apply external heat to the whole body, and by cloths wrung out of hot mustard-water over the region of the heart and stomach. Collapse may rapidly succeed, with cold, clammy moisture of skin, and often distinct droj)sof sweat ujion the brow, shrunken and contracted features, reduced bodily temperature, almost imperceptible and often irregular pulse, short and feelile or ])anting resjiiration. To the treat- ment of shock add hypodermic injections of brandy, gss to ,^j, repeated every five minutes, in the arms; or ether, 10 to 30 minims, every ten minutes; strychnia, gJj^ grain ; or weak liquor ammonise, 5 to 10 minims, may be injected into the veins ; large hot-water enemata should be given witli the preceding remedies. Electricity, applied to the regit)n of the heart, sliould be used. .Vs the most unfavorable cases will frequently recover if energetically treated, the efforts at restoration should not be relaxed until recovery is secure or death has occurred. If reaction be- gin, stimulation should in part give place to nutrition ; the patient must remain in the Jiorizontal position ; beef-juice, with brandy, should be given at first, and hot coffee and milk should soon be added, yubcuta- neous injections of morphia are very important in securing rest and quiet, or, if the morpiiia t'annot be taken, hyoscyamus may be combined or substituted. Finally, tincture of digitalis may be required if reaction is delayed, in 10 to 20 minim doses. External heat is always to be applied to the whole body, and (-loths wrung out of hot water over the stomach and heart ; friction of the limbs may be usefully added. 8G{) OJ'i:i!.lTIVE SURflERY.

To the former treatment must now he addetl positicju ol' the l)oe formed at any part, but the apparatus is the same in each case. Fig. 420. Fig. 421. Artificial foot. Artificial leg. COMPENSATIVE APPLIANCES. 863 Fig. 422. The foot should be of the same mechanism as in tlie aukle-joiut stump — nainely, a socketed axial bolt passing transversely through it, giving only Hexiou and extension (Fig. 421). The construction of the leg- piece is designed to give lateral support hx a well-sliai)ed and fitting socket ; a thigh-piece with joints in the steel side- pieces is necessary to sustain the limb, and elastic straps are sometimes added which are attached to a yoke strap over the shoulder. The kiur-Joinf rnnpiitdtion leaves a broad, well- covered stump, which readily takes direct support, and iience, with a well-adjusted a]>j)liancc, is ex- tremely serviceable. Tiie foot- and leg-pieces are the same as those already given. The knee-joint may be perfect in the motions of flexion and ex- tension, and the padded socket should be exactly adapted to the form of tiie stump. The thigh should lace up in front, and straps may be added to sustain the whole upon tiie shoulder. Tiie same apparatus is necessary when the amputation is at the point of election, for by flexion of the short stump the hearing is taken on the condyles of the femur in the same manner as in knee-joint amputation. The (hi(/h ampufafion rcipiircs a socket extend- ing to the hip, with bands attached which may be applied over the slioulder to support the appa- ratus. The construction of other parts is the same as in amputation at tiie knee. In cases of double amputation tiicse appliances may be adapted to both legs, so that the individual will liave good motion (Fig. 422).
