V V ^ TO JOHN BYRNE, M. D., LL. D., M. R. C. S. E., AS AN ACKNOWLEDGMENT OF HIS ORIGINAL AND MOST VALUABLE CONTRIBUTIONS TO THE SCIENCE AND ART OF THE ELECTRIC CAUTERY IN SURGERY ; HIS SUPREME PROFESSIONAL HONOR, HONESTY, AND COURTESY ; AND IN PERSONAL GRATITUDE FOR HIS TRUE AND CONSTANT FRIENDSHIP, THESE PAGES ARE INSCRIBED BY THE AUTHOR. Digitized by the Internet Archive in 2010 with funding from Open Knowledge Commons http://www.archive.org/details/electrohaemostaOOsken PREFACE This contribution relating to electro-hsemostasis and the electric cautery in general and special surgery, is issued to supplement the third edition of my work on diseases of women, in which the subject was referred to, but altogether too briefly discussed. The interest manifested by the profession in this sub- ject, the employment of the new methods of operating in other than gynaecological surgery, a number of recent im- provements in instruments and in the technique of oj^era- ting, and a larger experience confirmatory of the value of the principles and practice advocated, both prompted the undertaking and raise the hope that the results will be acceptable to the profession. The part of the work devoted to electro-hsemostasis may appear to be rather aggressive, not to say revolutionary, and therefore it might be judicious to give in this preface a statement explanatory of the principles involved and a preliminary argument in their favor; but past experiences remind me that it is unnecessary to do so. In former contributions to medical literature I have avoided all declamations and special pleadings regarding the merits of that which I had to offer, in order that I should have the opinion of the profession to guide me to rational conclusions regarding the value of my work. vi PREFACE. Having fared well in tLe past, I am perfectly satisfied to leave the present effort to tlie judgment of those for whom these pages were written — the thinking, reading, working members of the medical profession. My grateful acknowledgments are due to Dr. R. L. Dickinson for taking charge of the illustrations, which speak for themselves ; to Dr. W. H. Seymour for his val- uable laboratoiy work and demonstrations of the process of electro-hsemostasis ; and to Louis M. Pignolet, the maker of the electrical instruments.

Catgut ligatures, prop- erly prepared and sterilized, soon answered all the require- ments of the surgeon in so many operations that he has been disposed since then to rest satisfied in the belief that the ideal method had been attained, so vastly superior was the new way to the old. Even at the present time one is liable to be considered hypercritical and fastidious if he questions the utility and competence of the surgery of the day in controlling haemorrhage in incised wounds. Never- theless, the modern ligature has its defects and failings when employed in certain operations and in some con- ditions. Some of those who first used catgut as a ligature ac- knowledge that it is difficult to sterilize and keep perfectly clean, and that it is not altogether reliable in ligating blood vessels in the pedicle of an ovarian tumor, for example More recently it has been discovered that it is objection able in wounds which are septic or contain necrotic tissue Take, for example, a suppurating ovarian tumor or a pyo salpinx : the broad-ligament pedicle is nearly always sep 2 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. tic, and no matter how clean the ligature may be when applied it soon becomes contaminated by contact with the diseased tissue, and, being dead animal tissue, it adds of its own seK to the field for the culture of bacteria. A ligature thus contaminated is not absorbed, but acts as a foreign body for the promotion of evil and the interruption of the process of repair, and is responsible for the bad results which have sometimes followed when I had operated ac- cording to all the rules of modern surgery. Others have had similar failures from the same cause, if I may judge from cases which have come to my notice. On this account catgut is the worst material that can be left in a wound which is not perfectly free from germs of disease. Of minor importance, but still worthy of notice, is the fact that dry catgut is not very flexible and easily handled, and if softened by immersion in a sterilized or antise^Jtic solution it stretches or breaks, and can not be depended upon to close vessels and hold them. This tendency to stretch is increased by the softening which takes place while the ligature is in the tissues, and therefore haemorrhage may occur. This has happened in abdominal operations, and on that account many operators, even in the early days of modern surgery, preferred silk ligatures for much of their work. If I mistake not, the majority of surgeons at the pres- ent time use silk ligatures in ovariotomy, hysterectomy, and similar operations ; and yet the silk ligature does not meet all the demands of surgery. The objectionable features of silk are, that it is not absorbed bat remains in the tissues where it is placed, quiescent in many cases, but occasion- ally causing much mischief. The unfavorable behavior of the silk ligature has been so fully recognized by some of the leading surgeons that they have raised the question whether this non-absorbable ligature should ever be used in abdominal surgery. Judging from my own limited ob- servations and the meager records found in surgical litera- ture on this subject, it appears that silk ligatures either become encysted and remain where they are placed, or, INTRODUCTION. 3 becoming freed from the protecting exudate, wander about until they are thrown out by the eliminative process of suppurative or ulcerative inflammation. Fine ligatures of silk applied to small blood vessels in areolar and muscular tissue become walled in with repara- tive exudates and may remain indefinitely, but those used in abdominal operations are likely to work their way out through the skin or escape into some neighboring viscus. Under favorable circumstances the harmful action of silk ligatures has escaped observation, owing to the fact that they cause no trouble until long after recovery from the operation in which they were employed. If the silk is clean when used, no immediate disturbance of the jDrocess of healing is caused, and so far silk appears to be a perfect agent ; still, it is not so, for the necessary walling in of a silk ligature requires more time than the disposal of an absorbable ligature, and the quantity of new material left in the wound surrounding the ligatures retards the process of repair. On this account the tissues in the neighborhood of the wound remain indurated, and do not regain their elasticity and freedom from tenderness for a long time, even when union takes place promptly and without sujipuration. These facts regarding the slow recovery or repair caused by the presence of silk in the tissue, and the disposition of such ligatures to be thrown out in course of time, are illus- trated in an extirpation of the mammary gland which occurred in ray practice. The patient being spare of habit and to a slight degree hsemorrhagic, more ligatures were required than usual, and all of the fine silk on hand was used up, and so one ligature of thick silk had to be used. Healing took place without delay, but the tissues remained indurated and irregular, and fixed to the wall of the thorax for a long time. There were also slight pains at times and tender- ness. Two years afterward the patient returned for advice regarding an inflamed part about an inch in diameter, pre- senting all the signs of a small abscess, situated about an inch and a half from the original incision. The parts were 4 ELBCTRO-H^MOSTASIS IN OPERATIVE SURGERY. incised and a mass of exudate or scar tissue remov^ed with a curette. In this mass I found the large ligature which I had used in operating. The silk was in a state of good preservation, and only the short ends of the ligature pro- truded from the mass in which the ligature was imbedded. The patient rapidly recovered, and there was no return of the cancer one year and a half afterward. This shows that the whole trouble came from the ligature and not from the recurrence of the disease. Were this all of the evil that can be charged fairly against the silk ligature one might rest satisfied, but worse follows the use of ligatures of all kinds in abdom- inal and pelvic surgery. Ligatures apj)lied to the broad- ligament pedicles of ovarian tumors and Fallopian tubes are guilty of much wrong-doing. For example, unless the conditions are unusually favorable, the pedicle of an ovarian tumor can not be tied tightly enough to close the arteries in the way that surgeons say they should be ligated to make sure of controlling haemorrhage with cer- tainty. There is a liability, in thick pedicles, for the tissues to shrink under the pressure of the ligature and permit the vessels that have been temporarily closed to open again and allow bleeding to take place. This inefficiency of the silk ligature has been observed by Dr. Howard A. Kelly, so that he has adopted the method of ligating the pedicle in two sections, by including the ovarian arteries in one ligature and the tubal and uterine side of the pedicle in the other, and in addition to that he also ligates the larger vessels in the end of the stump. Whenever the tissues of the pedicle are rendered friable by disease or degeneration, it is well-nigh impossible to con- trol haemorrhage with a ligature of any kind. Silk is as bad as or worse than anything else, for it cuts the tissues if tied as tight as possible without breaking. These are some of the charges which can be brought fairly against the silk ligature as a means of immediately and permanently arresting haemorrhage. The subsequent INTRODUCTION. behavior of the ligature, and the character of the stump to be repaired after ligation, are still more unsatisfactory to both the patient and the surgeon. The pressure of the ligature upon the nerve tissue and the traction of the parts toward the point of constriction, especially in a short, broad pedicle, cause irritation and pain. There is a large mass of tissue projecting beyond the ligature which has to be disposed of by a process of degeneration and absorp- tion ; the ligature and the tissue of the pedicle beneath it have to be closed in by a deposit of plastic material, which in time is disposed of by absorption, and the ligature set fi'ee. During all these weeks or months required to com- pletely repair the stump there is oftentimes considerable pain and distress in the site ; nothing dangerous or alarm- ing but annoying. Not infrequently when a diseased Fallo- pian tube forms part of the pedicle there is a secondary attack, maybe several, of inflammation in the stump, caused by the tube remaining open and giving out septic material. These sequelae have passed unnoticed by many surgeons, and are lightly spoken of by others, presumably because there was no danger to the life of such patients ; but the best operators have given attention to the subject, and, having watched their results with scientific accuracy, have observed these results and recorded them. What becomes of silk ligatures that are left in the peritoneal cavity is a question of vast importance. One opinion which for a long time prevailed was that a silk ligature applied to a broad-ligament pedicle becomes en- cysted and remains quiescent for all time. Exceptions to this rule were admitted, and were accounted for by some unclean operating or a septic ligature that caused suppura- tive inflammation in the stump by which the ligature was set free or found its way into some neighboring viscus. This is almost altogether incorrect. Occasionally it may happen that a ligature becomes firmly fixed to the broad ligament by an exudate and remains imbedded for all time, but that, I believe, is the exception, not the rule. 6 ELEOTRO-H^MOSTASIS IN OPERATIVE SURGERY. This very interesting question of tlie disposal of silk ligatures, as a rule, has not yet been answered fully, so far as I can ascertain. Guided by my own experience, I be- lieve, as already stated, that ligatures left in the peritoneal cavity are at first encysted and finally liberated, and remain in the peritoneum or escape through some of the viscera or the abdominal wall. So many cases of this kind have been reported that I need say nothing on that subject, except that they make their exits by being first set fi'ee fi'om the plastic stuff that surrounds them and travel outward by a pi'ocess of ulceration or suppuration and necrosis of the tissues in the way of their outgoing. At least that is the way of it according to my own observations. By way of illustrating what has been said about liga- tures being set free in the peritoneal cavity, I give the history of a specimen brought to my clinic at the New York Post-Graduate School by Prof. F. Ferguson. The patient from whom the specimen was obtained died of some thoracic disease, and while making the autopsy Professor Fero;uson learned that she had had her ovaries and tubes removed about one year prior to her death. The pelvic organs were removed entire, and I had every facility for their examination. The stumps were rounded off even with the posterior surface of the broad ligaments, showing that all that portion of the stumps outside of the ligature had been disposed of, and also the exudate that had been thrown around the ligatures to inclose them. The ends of the tubes were open. The ligatures of thick silk were found in the most dependent part of the sac of Douglas, quite free fi'om, but resting upon, the thickened peritoneum. The thickening of the peritoneum in the sac resulted from cellular proliferation and exudation, jDOSsibly brought about by irritation arising fi^om the presence of the ligatures. What would have become of the ligature finally, if the patient had lived, I know not. From among a number of cases recorded in which the ligature migrated I give the following : The patient had INTRODUCTION. Y s, severe puerperal peritonitis followed by chronic ovaritis and varicose veins of the broad ligaments. This, with very extensive old adhesions of all the j^elvic organs, caused so much suffering that it became necessary to operate. The tubes and ovaries were removed, the veins closed, and ad- hesions separated. One ovary and tube were found high up and held in this abnormal position by adhesions. When these were ligated and removed the stump rested near the lower part of the wound in the abdominal wall. The recovery was quite favorable, but about two months after the patient was dismissed she returned, complaining of pain in the scar near its lower end. The scar at that point was stretched, and there was a slight protrusion, not un- like a beo-innino; hernia, but there was some fluctuation and flatness on percussion, which led to a diagnosis of abscess. An opening was made and a small amount of serum and tissue debris escaped, but not any visible pus. The sinus was washed out, but it would not close. A little serous dis- charge continued for six weeks or two months, when she re- turned for treatment. Suspecting the presence of a ligature that had escaped from its environing exudate, it was fished out with a blunt hook, and then healing soon closed the sinus. Having observed these disappointing actions of liga- tures, I naturally looked for something better in surgical hsemostasis. This I found in the work of Dr. Thomas Keith, who taught me his method of treating the pedicle in ovari- otomy by the clamp and cautery, which in theory and prac- tice was most satisfactory. No doubt this feature of his operating contributed largely to making him the most suc- cessful ovariotomist of his time. The experience of years and a large number of operations in which his method was used has fully confirmed my confidence in this way of controlling haemorrhage. The method of treating the pedicle of ovarian tumors employed by Keith and his followers was never adopted by surgeons in general. This was due, apparently, in part, to ignorance of the principles of the method, but more especially to the diflficulties in the 8 ELECTEO-H^MOSTASIS IX OPERATIVE SUR&ERY. tecliniqne cf tlie procedure.

Occasionally in treating a thick mass of tissue the central portion of it becomes heated before being fully com- pressed, and the blood is coagulated in the vessels and leaves dark strips or general staining of the tissues, which causes some opacity in the parts. As a rule, however, the blood is pressed out of the vessels before the desiccating begins, and the stump is sufficiently translucent to enable the operator to see any vessel that has escaped. The indica- tions or requirements for closing vessels are in this way thoroughly fulfilled by the complete fusing together of the walls of the vessels so that they do not, in fact can not, come apart. This I have demonstrated again and again. While I found in my first observations that the hsemostasis 20 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. was immediately complete, I was suspicious tliat when the tissue became softened by absorbing moisture the vessels might open up and subsequent bleeding might return, but many clinical experiences and experiments settled that question beyond all doubt. CHAPTEE III RESULTS OF THIS HEMOSTATIC PEOCESS To my clinical observations I liave the satisfaction and pleasure of adding an experiment made by Dr. R. L. Dickinson. He placed a mass of tissue, one jDart of whicli was treated by this method, into non-sterilized water and Fig. 11. — A, untreated end; B, desiccated end. let it remain immersed for about seventy-two hours. At the end of that time the tissue not treated was a soft pulpy mass that broke down under pressure of the iingers ; while the desiccated portion remained iirai, though somewhat softened by the water, but with no separation of its com- ponent parts, neither could he iind any part w^here cleavage 21 22 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. or dissection could be made. I have repeated this experi- ment many times with the same results.

RESULTS OF THIS HEMOSTATIC PROCESS. 23 Finally, I may state tliat I have employed this method in over two hundred abdominal operations, and in many vaginal hysterectomies and other operations, and have never had secondary haemorrhage in any of them. These are the facts regarding the method as an haemo- static. There still remains the question of the subsequent behaviors of the ends of the vessels and the tissue thus treated — in other v^ords, the process of repair. From all the facts that I could gather on this subject in actual practice, I concluded that the desiccated tissue became first hydrated and then reorganized, and remained as permanent structure, closing for all time the ends of the blood-vessels, lymphatics, and canals so treated. There was still an uncertainty on this point, until Dr. W. H. Seymour, the pathologist to my department in the college, conducted a series of independent experiments in the Hoaglancl Laboratory. The account of these observations and experiments by Dr. Seymour and the illustrations made under his supervision are as follows : In the first place, the doctor observed that an artery a quarter of an inch in diameter was reduced to about a twelfth of an inch in thickness (see Figs. 11, 12, 13), and that the structure of the tissues was rendered amorphous by the heat and pressure. The lumen of the artery was oblit- erated completely, so that no trace of its original structure could be found. (See Figs. 14, 15.) A piece of tissue, con- taining arteries, nerves, fibrous, muscular, and areolar tissue, was treated in the same way and presented the same amor- phous appearance and complete closure of the arteries. So completely fused together were the walls of the lumen of the arteries that no trace of the original structure could be found, neither could the lumen be reopened by teasing the microscopic specimen. Observations were made of sections of the Fallopian tubes, appendix vermiformis, ureters, and other canals lined with mucous membrane, and the same amorphous con- ditions were found. The structure of the mucous mem- 3 24: ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. brane was so completely changed that no part of its original structure could be found by microscopical examination.

RESULTS OF THIS HEMOSTATIC PROCESS. 25 The thorouglmess of the closure of the arteries was demonstrated by attaching a fountain syringe to the opening of the artery and using double the ordinary blood pressure without opening the closed end of the vessel. The advantages that may be fairly claimed for this wav of controlling bleediog in surgery are, that it is certain and reliable in closing isolated vessels or those imbedded in masses of tissue, like an ovarian-tumor pedicle for example. At the same time that bleeding is arrested, all lymphatics are sealed up, which prevents septic absorption. The tissues of the stump are reduced to the smallest possible size, and there are no raw surfaces left to form adhesions to the abdominal or pelvic viscera, nor any foreign sub- stance left in the tissues to cause mischief, advantages that can hardly be overestimated. Tissues which have become friable by disease and can not withstand sufficient pressui'e of a ligature to control bleeding are easily managed by this method. When the tissues that form the pedicle of a suppurating ovarian cys- toma or a pyosalpinx contain septic germs, a condition in which the ligature is most objectionable, a better and much safer stump can be made in this way. A ligature used when the tissues are in this condition, especially a catgut one, is very objectionable, for the dead animal tissue of such a ligature forms a perfect medium for the development of disease germs. It is also the only way that canals lined with mucous membrane — the Fallopian tube and the appen- dix veiTQiformis, for example — can be permanently closed. This will be referred to when discussing special operations. Nerves that accompany the vessels are immediately de- vitalized, and hence there is less pain and irritation in the stump. The heat employed sterilizes the parts involved, and therefore the operation is perfectly aseptic. To these many advantages may be added that it leaves the stump of a pedicle or the end of an artery in a condition re- quiring the least reparatory care, so that recovery is more prompt, uneventful, and complete. 26 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. Macroscojjic and Microscopic Appearances of the Fallopjian Tube treated icith the Electro-hcemostatic Forceps. These observations have been made on two stumps, taken from canine subjects, at the end of the third and tenth day of the healing process, following laparotomy. In each instance, prior to the application of the forceps, careful antiseptic measures were followed out in the exposure of the tube and uterus. The haemo- OPPOSITE TUBE STUMP °^ TUBE CEIRVIX Fig. 16 represents the tube removed at the end of the third day of the healing process. static forceps of the smallest size was placed on each stump for one minute, and an electric current used of sufficient strength to raise the temperature of the for- ceps to 180'.

At the point of application is noted a constriction corresponding in width to the cautery clamp, on the surface of which are numerous corrugations which correspond to the same in the blades of the instrument. A decided compression is shown to exist at the point of application, and also a quantity of recent lymph RESULTS OF THIS HAEMOSTATIC PROCESS. 27 and solid exudate found over the free end of the stump. Considerable ecchy- motic haemorrhage is noticed at the uterine end of the area treated with the haemo- static forceps. The free end of the tube is seen to be softened, and corresponds in appearance with what might be expected in the earlier stages of coagulation necrosis. On an examination of the lumenal portion, macroscopically, the canal is seen to be obliterated. Microscopic Appearance (Plate I, Fig. 1, longitudinal section). — Under the low power (Plate I, Fig. 2) the mucosa and submucosa are everywhere infiltrated with countless small round cells ; the blood-vessels are obliterated, their lumena being compressed. The free edges of the mucous membrane are seen to be in apposition, no distinct line of demarcation (lumenal) being apparent. Considerable softening exists in the outer portions of the wall of the oviduct. The small round cells can, with little difficulty, be traced far back into the muscular layers of the organ. Under the high power (Plate I, Fig. 3) are seen countless small round cells of the reparative process, intermingling with which are also fine fibrous elements sur- rounding small and large areas of coagulation necrosis. On studying the lumenal portion of the mucous membrane the small round cells of one surface seem to merge or blend with those of the opposite, thus preventing the recognition of the lumenal margin of the mucous membrane. Macroscopic Appearance (Fig. 17). — The tube resembled, in its treated portion, that of the third-day specimen, the treated area, however, being much duller in * -rrm %. • iBmJVi ''i^BIl l^mL -^^m i^H sB m jSm i \bSSS0^^'^'^ FIVE TIMES LIFE SIZE.

The duller portion represents marked areas of coagulation necrosis, together with some haemorrhage by diapedesis, shown in adjacent neigh- borhoods. The mucos;T3 of the two walls of the tube are seen to be in contact, thus produc- ing actual obliteration of the lumen of the tube due to active jyroliferation of the cells of the mucosa and infiltration of small round cells.

CHAPTER lY ELECTEO-H^MOSTASIS IJST OVARIOTOMY The part of this work relating to tlie management of hsemorrhage in abdominal and pelvic surgery is of necessity fragmentary, as it treats of hsemostasis in this class of ojDer- ations only. In describing this method of arresting the haemorrhage which occurs when making the abdominal section, separating adhesions, and treating the pedicle in ovariotomy, I shall follow the steps of the operation in the order in which they have just been named. The Jiijemorrhage in ahdonmial section comes mostly from the vessels of the skin, and should be arrested if at all free before dividing the deeper stmctures. The vessels should be seized with the artery haemostatic forceps and heated under pressure until they are closed. The method of treating small vessels in incised wounds is fully de- scribed under the head of extirpation of the mammary gland, which will be described in a later chapter. If the in- cision in the deeper structures of the abdominal wall is made in the median line, as it should be, and the large veins that are sometimes found in the peritoneum are avoided, no important haemorrhage occurs. The advan- tages of treating bleeding vessels in this part of the oper- ation are that no ligatures are left in the wound, and the injury of tissue caused by twisting the arteries or bruising them wdth compression forceps is avoided, and therefore the tissues are left in a better condition to heal promptly. It is my opinion that this is a very important factor guarding against subsequent ventral hernia. 30 ELECTRO-H^MOSTASIS IX OVARIOTOMY. 31 Adhesions of the omentwni to the cyst wall or tumor are treated by making traction upon the cyst wall to bring it and the adherent portion of the omentum out of the ab- dominal wound. A narrow-bladed forceps is applied to the omentum, close to the cyst wall, and the portion in the grasp of the forceps heated under pressure until fully desiccated. The portion thus treated is divided near to the cyst wall but in the line of desiccation. See Fig. 18, which shows a part that has been treated and divided, and another portion in the grasp of the forceps. In cases hav- ing a large portion of the omentum surface attached the adherent part can not be brought out of a small-sized Fig. 18. — The treatment of omental adhesions. wound far enough to reach the free portion to be separated. In such conditions the incision should be enlarged suffi- ciently to facilitate the operator's manipulations partially Avithin the abdominal ca\dty. Great care is necessary in such cases to protect the intestines from the heat while the forceps is being used. Fortunately such adhesions are veiy rare. The omentum being thin and the vessels small, only about twenty to thirty seconds are requii'ed to close them. In rare cases, when the omentum is thickened by inflam- mation, and the vessels very much enlarged, a minute of the heat may be required. 32 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. Fig. 19. — Artery forceps. Adhesions of the A'p'pendix Vermiform is. — The appendix is found adherent in pyosalpinx quite frequently, and is discussed in connection with that subject. Suffice it to say here that when the appendix is adherent to an ovarian tumor it should be removed with the tumor. The method of removing the appen- dix is given in the chapter on appendectomy. The raw, bleeding surfaces left after separation of ad- hesions to the wall of the abdomen, deep down in the sac of Douglas or elsewhere, are treated first by seizing the largest bleeding vessels with the artery forceps (see Fig. 21) and closing them. Then the oozing from the very small vessels is stopped by using the dome-shaped instru- ment. (See Fig. 35.) This is slowly passed over the sur- faces until all oozino; ceases. The operator must guard against letting the intestines, uterus, or bladder come into contact with the dome instru- ment when it is in use. With ordinary care the needed protection can be assured by having the patient in the Trendelenburg position and keeping the abdominal and pelvic viscera out of harm's way with sponges and retractors, as illustrated in Fio;. 21. The technique is exceedingly simple, and^ the results most satisfactory compared with the old way of ligating the larger vessels (always a most difficult thing to do) and using persulphate of iron or hot water to stop the oozing. Fig. 20.— The dome. In fact I never was able to arrest bleeding and oozing com- pletely and quickly, and make the parts clean and dry in pelvic surgery of this kind until I devised this method of operating. ELECTRO-H^MOSTASIS IN OVARIOTOMY. 33 Intestinal adliesions are managed by makiug gentle traction and stretching the adhesion so that the forceps can be placed between the cyst wall and the intestines. "While the pressure and heat are being applied, the shield forceps should be placed on the side toward the intestines to protect them. When this is impossible, owing to close and extensive adhesions, the intestine is dissected away Fig. 21. — Protecting the uterus from the forceps. from the cyst in such a manner as to leave a portion of the external coat of the cyst wall on the side of the intestine. These flaps are brought together over the raw surface of the intestine and seized with the forceps, compressed and desiccated. (See Fig. 22.) In doing this the shield forceps should be used to keep the heat from reaching the intestine. This instrument 34 ELECTRO-HiEMOSTASIS IN OPERATIVE SURGERY. resembles an ordinary compression forceps, but has thin^ flat shields instead of jaws, as shown by Fig. 23. The shields are constructed of thin blades of steel coated with a substance which is a poor conductor of heat, such as hard rubber, and are longer and broader than the jaws of the electrical forceps. One side of each shield is flat and the other is beveled, as shown, so that the inside edges are chisel shaped. The flat sides are placed uppermost, close against the electrical instrument. When properly placed, the shield forceps is locked with sufficient pressure to re- FiG. 22. — The treatment of intestinal adhesions. tain the desiccated stump for inspection after the other instrument is removed. Adhesions to the rectum (the most difficult of all to manage) are treated in the same way as intestinal adhesions, with this difference, that when the adhesions are very strong, and the cyst wall changed in structure by inflam- mation, a part of the cyst wall should be left attached and its lining membrane destroyed with the dome cautery. Adhesions of the bladder to the tumor are treated by dissecting off the bladder and then closing the peritoneum ELECTRO-H^MOSTASIS IN OVARIOTOMY. 35 over the bladder witli fine catgut sutures Adliesions that are recent, not very extensive, and easily separated, are treated by touching the raw surface with the dome cauteiy at a temperature of 180°, to arrest any oozing that may take place. The Pedicle.— T\iQ cyst sac or tumor being withdrawn from the abdominal cavity the pedicle is examined with regard to its length and thickness, to determine the point at which it should be divided, and the size of forceps or clamp required for its treatment. Small and medium-sized pedicles call for the smallest pedicle forceps, illustrated by Fig. 24, and constructed as follows : The instrument is jointed at the distal end by a detachable lock, and has a projection on either blade at the proximal end of the jaws, which prevents the tissues fi'om spreading when the foi'ceps is closed. The handles lock with the usual catch near the proximal end. Larger pedicles require the clamp forceps, illustrated by Fig. 25, and constructed in the same man- 36 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. ner as the small pedicle forceps, but having a movable section which can be closed by a screw attachment. By this means the pressure is made parallel to the heated jaw, and a greater and more equal compression is thereby ob- FiG. 25. — Clamp forceps for larger pedicles. tained. The forceps selected is applied at the point where the pedicle is to be divided. One or two fixation forceps are applied to the base of the tumor, and the pedicle divided between them and the haemostatic clamp, leaving a portion of the pedicle projecting above the blades of the clamp to prevent slipping. This portion should be cut off close to the forceps just before removing it. The shield forceps is applied beneath the haemostatic forceps to pro- tect the abdominal wall from the heat, and to keep the stump from falling back into the pelvic cavity when the haemostatic forceps is removed. (See Fig. 26.) This enables the operator to inspect the stump and see if it has been properly treated before it is dropped. If any portion of the stump, or the whole of it, indeed, is not fully desiccated, the forceps can be reapplied and the treatment completed. Sterilized vaseline should be applied to the inner surface of the blades of the forceps, to prevent the stump from adhering and to permit the forceps to come off easily. The forceps should be closed only to the first notch in the catch, and when the current has been turned on and used for about half a minute the compression should be completed by clos- ing the forceps to the last notch. During the time that the electric current is being used the operator should examine ELECTRO-H^MOSTASIS IN OVARIOTOMY. m tlie other ovary and tlie otlier pelvic organs to see if any- thing more in the way of operating is required. An unusually short, thick, broad pedicle, that can not be accommodated in the largest clamp forceps, should be treated in three sections. The outer border, which con- tains the ovarian vessels, should be grasped wdth the for- ceps used for vaginal hysterectomy, treated in the usual way, and divided; the inner border should be treated in the same way ; the middle portion, or third section of the pedicle, if not vascular may be cut oif without treatment, Fig. 26. — Treatment of pedicle of ovarian cyst. (Diagrammatic.) and the edges of the peritoneum of the stump closed with fine sutures. If the middle part is vascular it should be caught in the pedicle clamp and treated like the other sections. 38 ELBCTRO-H^MOSTASIS IN OPERATIVE SURGERY. For one wlio is not familiar mth this treatment of the pedicle it is difficult to tell when the treatment is sufficient to be reliable. This was to me a most difficult question in my first operations, but I soon learned that if there was no disposition to bleeding when the clamp was removed, it could surely be trusted. CHAPTER V ELECTEO-HiEMOSTASIS IN MYOMECTOMY AND ABDOMHSTAL HYSTEEECTOMY I DID a number of successful myomectomies in pedun- culated iibroids, and in all I found difficulty in control- ling the bleeding with the ligature. Such was my ex- perience that I never dared to remove a sessile subperi- toneal fibroid until I obtained the haemostatic forceps. Since then I have succeeded equally well with all forms Fig. 27. — Treatment of pedicle of a fibroid. The cnff of peritoneum and the cap- sule gathered together, drawn outward, and seized by electro-haemostatic forceps. of subperitoneal fibroids. The method of operating when the pedicle is long enough is to apply the forceps in the same way as it is used upon the pedicle of an ovarian tumor, compress and desiccate it, and then cut away the tumor. 4 39 40 ELECTRO-H^MOSTASIS IX OPERATIVE SURGERY. When the pedicle is short and the fibroid is in contact ■with and yet movable upon the middle coat of the uterine wall, the capsule is divided all around on the tumor one to two inches from the uterus. It is then dissected off with ^. , drawn forward. V^ Fig. 36. — Removal of diseased tube and ovary by the forceps.

I49 neered " door ; that is, a door formed of a glued-up pine core, and veneered on sides and edges with a hardwood veneer, forming a perfectly plain surface, which may be kept filled and polished. Marble doors have been used to a very limited extent, but they are heavy and expensive, hard to move, and unless the hinges or pivots are very hard, and carefully made and adjusted, they are liable to wear down and sag. The mar- ble, however, is porous, easily stained, and altogether the most objectionable of all. Bronze doors would answer best, but they are too expensive for hospitals as a general rule. HOSPITAL PLUMBING In the matter of plumbing, improvements in material and fixtures have reduced in a great degree many of the difficulties formerly encountered in the proper equipment of hospitals. Fixtures for almost all purposes are now made of heavy glazed earthenware, in designs or forms needing no encasing or surrounding material. A porcelain bath tub is a typical example ; when set it is complete, no wood curbing or boxing being required, as in the case of the older copper-lined tub. The price of these earthenware goods is practically within the reach of an institution with but limited means ; for instance, they are now being used in a certain small vil- lage hospital, costing less than eight thousand dollars. In some ways, however, the " improvements " in modern plumbing fixtures are of doubtful character, such as a wash basin with supply and waste cocks operated by treadles on the floor. In a general way the questionable value of these improvements lies in their complexity, rendering them diffi- cult to keep clean or to keep in order. The number of valve mechanisms, traps, wastes, etc., is almost without end, while the really desirable patterns are very few. In short, the simplest form of any fixture w^th its acces- sories is always the best, provided the construction is satis- factory. A plain " S " trap with vent connection seems at 150 ELECTRO-HiEMOSTASIS IN OPERATIVE SURGERY. tlie present stage of progress to be the best to be had, and a " standing " waste and ov^erflow the most satisfactory for general use. By a " standing " waste and overflow is meant a simple tube whose lower end fills the outlet of bowl, sink, or tub, and whose upper end is open, the tube standing vertically, and its height determining the depth of w^ater in the fixture. Such a waste is the simplest possible thing to keep clean, and, being wholly exposed, is always open for complete inspection. The trap should in all cases be placed as near the outlet of the fixture as it is possible to get it, and the w^aste from fixture to trap should be perfectly straight. The strainer in the outlet of the fixture should be removable so that the waste can be thoroughly cleaned. The bad air in many bath and toilet rooms is due to the fouling of the inaccessible waste and overflow connections from fixture outlets to traps, and these same connections may easily form favorable germinating places for dangerous bacilli. The whole aim in the plumbing of a hospital, as well as any building, should be the greatest possible simplicity. The number of fixtures should be cut down to the lowest possible minimum, they should be grouped together as nearly as possible to a few vertical lines, and the fixtures themselves should be of the best material and plainest design and construction consistent with specific require- ments. The arrangement of fixtures in the various rooms should be such as to permit all piping to and from them to be run in the most direct manner and so as to make the distance from main lines of supply and waste as short and as straight as possible. All waste pipes should have a pitch of not less than one quarter of an inch to a foot. All bends should be of large radius and clean-outs placed at frequent and readily accessible points. All connections, at least in the rooms containing the fixtures, should be made with screw joints, so as to be easily taken down and put up. ASEPSIS AND ANTISEPSIS IN SURGERY. 151 Where the means at hand will permit, the main lines of waste, soil, and vent pipes should be of galvanized wrought iron screwed together, rather than the usual form of cast iron with lead calked joints which can not be depended upon to remain tight. The principle of placing all bathrooms, water-closets, etc., in a pavilion separate from the hospital wards is good. In such an arrangement the pavilion is reached by short, connecting corridors having openings on both sides so that a cross current of fresh air is always maintained between the main building and the pavilion containing the plumbing. This separation, of course, requires space and money, and may not always be had ; some modifications costing less may, however, be within reach, and the nearer the ap- proach to the ideal the more satisfactory will be the result. Whether the plumbing fixtures are contained in a sepa- rate pavilion or inclosed in the main building, the main ver- tical lines of piping should be placed in a specially arranged vertical shaft extending from the house drain at bottom up to and above the roof. This shaft should be large enough to permit of the proper spacing and arrangement of all pipes, and for a man to conveiiieutly reach all connec- tions and branches to fixtures. The branches to fixtures should be run in this shaft so that there would be only the supply cocks and trap visible in the room. If impossible to reach a fixture by a branch in the shaft, then only so much as is necessary should be run on the ceiling of the room below so as to avoid horizontal pipes at or near the floor, as these present almost insurmountable obstacles to thorough cleaning. The vertical shaft containing the main pipes should have open iron gratings at floor levels instead of solid floors, and should have no openings into it except a small " manhole " or door at the bottom, the various floor levels being reached by an iron ladder built in the shaft itself. To complete the scheme the shaft should be heated so as to produce a strong upward draught in the soil, waste, and vent pipes and their 11 152 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. branches, so as to quickly and thoroughly oxidize any or- ganic matter adhering to their sides. Floor drains should be avoided as far as possible, and where necessary should discharge into a water-supplied sink placed in a shaft as already described or in a room below. The sink being connected to the waste ]3ipe in the same manner as other fixtures, the outlet in the floor should have a cover which could not be closed until a cap had been screwed down over the waste, thus insuring complete isola- tion of the floor drain from the main drains and wastes. The sink or basin in an operating room should discharge in the same manner as the floor drains, so as to have no di- rect connection with the drainage system. Polished brass or nickel-plated piping requires too much time in cleaning for general use ; unpolished brass pipe and fittings, painted with enamel paint, will be found more ser- viceable where economy of labor is to be considered. Much attention and care is necessary to make water- tight connections where pipes pass through tile or similar flooring, especially hot- water pipes, so that the floors may be thoroughly washed without leaking. HEATING AND VENTILATION OF HOSPITALS Possibly no part of hospital construction has received more attention than the heating and ventilating. The amount of fresh air required for each patient and its tem- perature have both been satisfactorily determined ; the prac- tical operation of supplying the air, warming it, and causing it to circulate completely throughout the whole of each room is beset with many difficulties. For ordinary work it has been found more desirable to divide the problem into two distinct parts, one the heating and the other the venti- lating. In this method the air is heated, by large heating stacks located in the lower part of the building, to the tem- perature desired for the room, say 70° F., the air being at this comparatively low temperature can not counteract the cooling effect of doors and windows and walls ; to do this ASEPSIS AND ANTISEPSIS IN SURGERY. 153 direct radiators are placed at proper points in tlie rooms to be heated. This system works well, but the direct radi- ators in the rooms rapidly collect dust and are very difficult to clean. A more satisfactory but a more expensive method consists in heating the ^vhole volume of air, at a central point or station, to nearly the temperature required by the various rooms, the air passing along main ducts or con- duits to the vertical flues leading to the rooms. At the base of each vertical flue is placed a separate and inde- pendent stack or indirect radiator, w^hich further heats the air to the temperature required. In this method, every room governing its own temperature, the air may be suffi- ciently warmed to overcome the cooling effect of outside walls, doors, and windows. This method would probably be as near an ideal scheme as possible to provide. The matter of automatic control of heating surfaces, such as stacks and radiators, has been brought very near perfection by vaiious forms of thermostatic valves operated by the temperature of the rooms they control. These valves have been found to act with great certainty, so that the temperature may be maintained within a variation of a degree above or below the required temperature. The thermostatic valves are applicable to both systems described above, and as it eliminates the necessity of depending upon attendants to operate hand valves, the temperature is more uniformly maintained. In the best work the air is filtered through screens of gauze before entering the heating chambers. These screens take out nearly all the dust, so that the air in the flues and ducts is practically clean. A fiu-ther application of the screen system to special rooms, such as operating rooms, would be of great advantage. It has been found that by passing the air through screens formed of sterilized cotton batting it is not only cleaned of dust but is also sterilized, and the advantages of sterilized air in an operating room is of course obvious. This steri- lizing is readily accomplished by arranging a set of cotton- 154 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. batting screens in the flue leading to the room where ster- ilized air is required, the screens being made somewhat upon the principle of a photographer's " plate-holder," allowing the frame to be withdrawn for the purpose of changing the cotton fi'om time to time, the frame sliding in and out of a trunk or other device built in the flue in very much the same manner as a plate-holder is put into a camera. The increased resistance offered by the cotton would of course require a stronger draught or pressui'e of air in the flue, but there is nothins; in the scheme which would make it impracticable. Direct-indirect radiation should never be used where an indirect system can possibly be aiforded. The direct-indirect scheme, as is well known, consists of a radiator -with a " box base," into which air is admitted through an opening in the wall directly behind it, the air entering the base of the radiator passes over it, and, be- coming heated, enters the room. It is impossible to prop- erly filter the air with this method, and it is also impossible to properly regulate the temperature or supply. As a mat- ter of economy it may answer for some small unimportant rooms in case an outlet flue is provided leading to a main exhaust stack or duct. Storerooms, clothesroom, and closets should not be over- looked, but should have as thorough ventilation as any other rooms. This is often neglected. Lavatories and rooms containing water-closets and urinals should be ventilated throuo-h the fixtures — that is, the air should be drawn out of the room through the bowls of the fixtures themselves and conveyed by separate flues to the top of the building. In this way all odor may be entu'ely eliminated from these rooms. Xo building can be thoroughly ventilated without the use of a mechanical system, including the use of fans or blowers. Generally, it ^vill be found best to provide two sets of fans, one to force air into the rooms and the other to draw it out. ASEPSIS AND ANTISEPSIS IN SURGERY. 155 All rooms should be under a slight pressure, so that the warm air of the room will be escaping through the cracks and openings around doors and windows instead of the cold ail* outside leaking in and causing draughts. Double sash or double glazing will be found of great service in making the temperature of a room more uniform, as well as reducing the consumption of fuel. It will also have the effect of reducing the cost of the whole plant, as the glass in windows is by far the most effective medium in cooling the air, and is a very important factor in deter- mining and proportioning the heating surfaces and other parts of the heating system. The system of exhaust flues and ducts is quite as im- portant as the supply, and should be as carefully develoj)ed. The location of registers in the rooms is also a very im- portant item in securing a complete cii'culation of air in all parts of the room. ExjDerience has demonstrated that they should both be placed on the same side of a room and near together, the supply being about eight feet above the floor and the exhaust at or near the floor level. In furnishing hospital rooms and wards the same rules should be followed as in the construction of the building. The furniture should be such as mil not lodge dirt or absorb the germs of disease. Simplicity in design and construction guards against the accumulation of dust and dirt, and the material used should be impenetrable as far as possible. .Metal bedsteads and washstands are the best in use at the present time when well plated. When these expensive articles can not be afforded, white enamel iron answers as well. Bureaus and cabinets should not be used as a rule ; but if permitted, to please lady patients, they should be severely plain, and enameled within and without. Such fui'niture is easily kept clean all the time, and can be sterilized when the room is treated by disinfection in the way to be hereafter described. CHAPTEE XYI ASEPSIS AISTD ANTISEPSIS (cOISTTINIJEd) AccoEDijsTG to my observations most of the imperfec- tions in carrying out aseptic methods in surgery occur in admission of patients and the management of their clothing. To guard against all possible infection from without the hospital requires a thorough disinfection of everything which conges into the building. Patients do not always know that they have been exposed to contagious disease ; sometimes they will not admit the exposure if they do know of it. One may not disregard this possible danger of pa- tients bringing from infected parts of the city sepsis and infectious diseases. The only safe course is to insist upon the sterilization of every new patient immediately upon her arrival and the disinfection of all her clothing. The method which I practice is as follows : The patient is at ohce taken to the dressing room adjoining the bath- room, where her clothing is removed and put into a clean bag and sent to the sterilizer. She leaves her street costume here and is conducted to the bathroom to receive an ammo- nia bath, and then dressed in a full change of clothing, which had been sent to the hospital the previous day and sterilized. All her clothing and everything which she has brought with her is sterilized by fonnaldehyde before being taken to her room. By this means the surgeon -will assure himself that his new patient has at least rightly begun her hospital life. The Preparation of a Patient for all Major Operations. — The previous night she receives a full ammonia bath, in giving which the nurse is careful to clean all folds of the 156 ASEPSIS AND ANTISEPSIS IN SURGERY. 157 skin. It is to be kept in mind that the nurse in charge of the bath must herself be clean. Thorough scrubbing should be practiced and then the body rinsed off with boiled water. The head should be shampooed with alcohol and quickly dried. This having been accomplished, the patient is dressed in sterilized under and night clothes and then put into the bed newly made up with sterilized bedding and bedclothes. A further cleansing is now given the whole abdomen in cases of abdominal section ; it is thor- oughly scrubbed with soap and water, then washed off with a one-in-two-thousand bichloride solution ; finally, a bichlo- ride compress (one in one thousand) and a clean binder are put on. The next morning this last cleansing process is repeated and a new compress and binder are applied. Now that the patient is clean, the utmost care must be exercised to protect her against contamination. She must be con- veyed to the ansBsthetizing room in a clean carriage or stretcher by clean attendants. The anaesthetist and the at- tending nurses are dressed in clean garments. The anaes- thetizing instruments have been cleaned the same as the instruments for the operation. If the narcosis is not given while the patient remains in her carriage, the couch or table on which she is placed is to be covered with sterilized ma- terial. As soon as the patient does not recognize her sur- roundings she is finally prepared for the operation by scrubbing the abdomen with soap and water, the hypogas- trium is then shaved with a sterilized razor, dried and bathed first in alcohol, then ether, and finally bichloride solution, one in one thousand. The umbilicus is covered with collodion, in case it is not to be incised ; a clean com- press and a new binder complete all and the patient is ready to be taken into the operation. The room used for operations is twice cleaned, once just after the preceding operation and again in preparation for the next one. Everything which is needed for the opera- tion, except instruments, is brought in ; then the formalde- hyde is introduced, and the room sealed for five hours. 158 ELECTRO-H^MOSTASTS IX OPERATIVE SURGERY. Blunt instruments are sterilized by exposure in live steam for fifteen minutes ; edged instruments are immersed in alcohol (ninety -five per cent) for ten minutes. Of late instruments are sterilized in formaldehyde ; and I believe it will prove to be the best method. When needed they are placed into the trays and covered with hot carbolized solu- tion. Formula : Carbolic acid, three per cent ; glycerin, twentv-two per cent ; water, seventy-five per cent. Xatu- ral sponges are washed for twenty-four hours in Javell water, the grit is taken out, and then they are washed in sterilized water ; they are preserved in five-per-cent carbolic solution. A careful rinsing in running sterilized water prepares them for immediate use. They should not be used a second time in abdominal work. Gauze sponges, the towels, binders, and gowns are cleansed by the ordinar}" steam apparatus. The primary gauze dressing is prepared in quantities by saturating it in a solution of carbolic acid, one paii: to glycerin eight parts. It is always ready, and requires but to have the excess of the solution rung out of it with a sterilized towel immediately before using. The suture material used is the ordinary braided silk, which is sterilized perfectly by boiling in salicylated wax for twenty hours, in five-hour fractions, with an hour inter- val. Suture material prepared in this way is perfectly sterile and can be kept so for any length of time. More than that, it ^vill remain sterile in the tissues as long as silver wii'e. This was demonstrated by both laboratoiy and clinical experiments many years ago. Cleansing and sterilizing the hands has always been one of the subjects which claim the most careful attention of surgeons. Even at the present time all methods, and they are many, are questioned regarding their efiSciency or prac- tical application. "Without discussing the subject I shall give the methods employed in my own practice and which have given the best results in re^rard to both the patient and the operator. The method employed is as as follovzs : Soft srreen ster- ASEPSIS AND ANTISEPSIS IN SURGERY. 159 ile soap is used with a sterile brush and running water that has been sterilized by boiling or distillation. The soap is thoroughly applied with the brush, then washed oi£ in the stream of water. This process is repeated four or five times, according to the condition of the hands. The water is made to play with force upon all parts of the hands and arms until all particles of the soap and dirt are washed off. Finally, the liands are placed in a solution of carbolic acid three per cent, glycerin twenty-two per cent, and water seventy-five per cent, and scrubbed or rubbed in with a brush. The excess of the solution is wiped oif with a clean towel, and they are ready for use. This is sufiicient treat- ment of the hands, unless the surgeon has been contaminated by examining or operating upon septic cases ; then a more careful disinfection is necessary. In such conditions of the hands more prolonged washing is employed, and then they are thoroughly anointed with carbolic acid pure one part and glycerin seven or eight parts. This is applied to the hands and arms and rubbed in with a soft, clean brush and allowed to remain about five minutes. It is then rapidly washed off with a strong stream of rapid-running water. The reason for doing this quickly is that the added water develops the caustic properties of the carbolic acid so that it will injure the skin if permitted to remain in contact with it. The advantages which this glycerin and carbolic-acid solution has is that the glycerin neutralizes the caustic properties of the acid and does not diminish its power as a germicide. Furthermore, it keeps the hands in good condi- tion. I am quite confident that this is a most satisfactory way of treating the hands so far as sterilizing them, not on the surface only but deep into the cuticle as far as germs go. The mercuric solutions which I formerly used hard- ened the skin and left living organisms beneath the crust of sterilized tissue. This hardened epithelium became softened in abdominal work and set free the living germs that escaped the sterilizing. That is one of the imperfec- 160 ELECTRO-H.EMOSTASIS IN OPERATIVE SURGERY. tions of the usual way of cleaning tlie hands, which has been pointed out, and has driven some surgeons to the use of gloves while operating. I prefer to wear gloves when examining doubtful cases, dressing wounds, or handling pathological specimens, and so keep the hands free from infecting germs that can not be destroyed by the method of cleansing which I practice, or any other method known to me. There is but one objection to the carbolic and glycerin solution, and that is the expense, but that is hardly worth naming in view of the advantages given by its use. The subject of room disinfection, which has been far from satisfactory in the past, has been greatly improved of late. Indeed, I feel sure that the recent improvements in this direction meet the requirements. The recent work of Ezra H. Wilson, M. D., is the most perfect that is known to me ; and I give here, by permission, his essay on this subject : The requirements to be met in a proj^er disinfection of an apartment in which there has been infectious diseases are : First. Absolute disinfection ; by that is meant the destruction of all infectious material. Second. Ease and rapidity in application. Thii'd. Economy. Fourth, The least possible damage to disinfected goods. The best disinfectant applicable to infected goods such as wearing apparel, bedding, etc., is heat in the form of steam, and it is safe to say that up to the present time no substitute has been found which will disinfect so thoroughly, rapidly, and economically as steam. The objections to its universal application are, that it can not be applied in the disinfection of apartments (walls, floors, ceilings, etc.), and that certain cheap grades of colored goods are often injured by it. The disinfection of apartments by the mechanical process of rubbing and scrubbing with disinfecting solutions, while veiy thorough, is tedious, expensive, and often dam- aging to painted and frescoed walls and ceilings. If, therefore, an agent can be found which can be used for the disinfection of apartments which will be an efficient ASEPSIS AND ANTISEPSIS IN SURaERY. 161 germicide and not cause any damage, it is very desirable to investigate it. Such an agent we believe we have in for- maldehyde gas, used in a proper manner and in proper amounts. The original method was to produce the gas by the oxidation of methyl alcohol in the presence of incan- descent platinum or platinized asbestos, and that is the method now used in the many lamps now in the market, and for which extravagant claims are made. There are many objections to these lamps. In the first place, and what is most important, they do not produce enough of the gas to be of any value. Second, they involve the use of an inflammable and explosive compound, the methyl alcohol, in proximity to an open flame. Third, they have to be lighted and shut up in a room where they are hidden from observation. Fourth, it is impossible in practice to regulate the lamp so as to get the maximum amount of gas, and so to allow of the escape of unoxidized methyl alcohol vapor. Roux, Baudet, Trillat, and others devised a method of evolving formaldehyde gas from formalin. Formalin or formol is a saturated (forty per cent) solution of the gas in water. If a quantity of formalin is mixed with an equal quantity of a five- to ten-per-cent solution of calcium chloride, it will be found that the boiling point of the mixture is considerably above 100° F. (103° to 106°), and the most favorable temperature for evolving formaldehyde gas is between 95° and 100° F. Thus nearly all the gas is evolved before the mixture is giving off steam. Moreover, it pre- vents the polymerization of the gas into trioxymethelene. I will now describe an apparatus for carrying out this process. PARTIAL DESCRIPTION OF AND DIRECTIONS FOR THE USE OF THE TRILLAT AUTOCLAVE The Apparatus is pached in Tivo Cases. Autoclave Case. — Containing autoclave with gauge; thermometer ; two handles and a tin case containing two outlet tubes and a wire to clean same. Case of Accessories. — Special lamp and small can con- taining alcohol to light same ; copper can for the formo- chloral ; tin can for kerosene ; cotton wadding for stuflfing cracks in windows, doors, etc. ; pair of spectacles to protect eyes. 162 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. Trillat Autoclave. — The vessel of the apparatus is made of heavy copper which is silver-lined and has a capacity of about one and one half gallons. The remainder of the apparatus is mostly brass, highly polished and carefully finished. The cover of the autoclave, which rests on a rubber band so that it can be tightened to avoid any leakage, is equipped with a pressure gauge, a sleeve in which the ther- mometer is placed and a stopcock by which one regulates the escape of formaldehyde gas. Lamp, — The apparatus is heated by means of a special lamp, the flame of which is fed by kerosene vapors. By a small screw one can regulate the heat, and by using the pump occasionally one can increase the heat. Formocliloral is a saturated solution of formic aldehyde and a neutral or indifferent mineral salt and absolutely free fi'om methyl alcohol. When heated under pressure, formal- dehyde vapors are evolved in a non-polymerized condition. Before putting the formochloral into the autoclave, it should be well mixed so as to distribute any precipitate which may be in the same. This deposit is not an im- purity, but on the contrary is one of the essential parts of the solution. Directions. — All cracks around windows, doors, fire- places, etc., should be stuifed to reduce the possibility of the gas escaping as far as possible. The formochloral is put into the autoclave, which should never be more than three quarters full, about one gallon or ten pounds by weight maximum. The minimum should not be less than a quart, or about two and one half pounds by weight on account of the possibility of injuring the auto- clave. One calculates that one pound of formochloral is sufficient for 2,500 to 5,000 cubic feet of air space. When tightening the cover, one should screw the op- posite bolts little by little so as not to press on one side of the rubber band. The apparatus after being closed is placed in front of the door of the room that is to be disinfected at a conven- ient height so that the stopcock is level with the keyhole. Carefully examine the outlet tube through which the formaldehyde gas is allowed to escape and see that it is free from any obstructions. Then put it through the key- ASEPSIS AND ANTISEPSIS IN SURGERY. 163 hole, allowing it to project inside of the room from about four to six inches ; then attach it to the autoclave by means of the screw bolt attached to the same. Put the thermome- ter in place, close the stopcock, and light the lamp. When the gauge indicates a pressure of a little over or about three atmospheres, carefully open the stopcock little by little, otherwise, should it be opened too rapidly, the liquid in the autoclave is apt to force itself out through the tube and is liable to produce disagreeable results, and for this reason it is well to take the precaution of removing the furniture and to cover carpets that may be directly in the vicinity of where the outlet tube projects. One knows that the gas flow is well regulated by the very gradual falling of the pressure as indicated by the gauge. The pressure should be kept as near as possible between two and three atmospheres. The vaporization can be considered finished in about one and one half hours when two and one half pounds of formochloral is used ; for the maximum charge, ten pounds, two hours sufiices ordinanly, and one must always stop the operation when the thermometer is over 135° and the pressure is below two or three atmospheres. When the operation is over the outlet tube can be withdrawn and keyhole stopped. It is preferable to allow the formaldehyde gas to re- main as long as possible, but from three to four hours' con- tact is sufficient for a good disinfection. Afterward it is necessary to air the apartment. To do this, enter rapidly, wearing the glasses and, without breathing, open the win- dow. One half hour later, one can without inconvenience enter the room. The order of formaldehyde can be neu- tralized more rapidly by injecting a little ammonia into the room. After the apparatus is cooled remove the thermometer, take off the cover of the autoclave, and empty the residue, which should be in a liquid form. Clean with water and dry with a linen rag. It will be seen from the experiment that the organisms protected by the folds of blanket were not killed, and this brings up another consideration, namely, that of penetra- tion. No matter how valuable this agent in a free state may be as a disinfector of superficially infected areas, such as walls, floors, and ceilings, it must be admitted that its 164 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY.

These were made at the City Disinfecting Station by R. B. F. Randolph, assistant bacteriologist. Table 1 No. Culture. 1 Anthrax. . . : . . 2 " 3 4 Typhoid S. P. A 5 Anthrax 6 7 Diphtheria . . . S. P.

Experiment No. 2 A Trillat autoclave was so arranged that a stream of formaldehyde gas could be forced into the inner chamber of the disinfecting oven. Sterile silk threads were immersed in cultures of sporulating anthrax, B. typhosus, B. diphtherise, and staphylococcus pyogenes aureus, and allowed to dry at ordinary temperatures. When dry they were inclosed in sterile filter-paper envelopes and arranged as described in Table 1. The conditions of the experiment were as follows : Quantity of formochloral used, 1,250 c. c. Capacity of the chamber, 340 cubic feet. 166 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. Vacuum at the beginning of tlie test, 14 inches of mercury. Vacuum after the admission of the formaldehyde, 11 inches. Gas was run in for thirty minutes. After the gas had ceased to flow, air was admitted until the o'auo'e stood at zero. One hour after the gas was shut off the chamber was twice exhausted and filled with air. The chamber was opened at 10 a. m. the following day. There was a slight odor of formaldehyde, but not enough to prevent a man from going in immediately. About two gallons of water smelling strongly of the gas was found on the floor of the chamber. The goods were dry and uninjured. It will be seen that the disinfection was far from com- plete, the anthrax not being killed except in one instance, and the other organisms in the more protected portions of the pile not being affected. This lack of penetration, how- ever, can be partially accounted for. The air admitted to the chamber immediately after the gas was shut off was taken through the sewer outlet, and in doing this the con- tents of the trap were sucked up into the chamber and possibly dissolved, and thus rendered inoperative a large amount of the gas. It was thought that a greater and more uniform degree of penetration could be secured by slightly heating the chamber, inasmuch as the diffusion power of a gas is largely influenced by its temperature. The following ex- periment was therefore made : The formaldehyde was generated in an autoclave built for that i^urpose by the Kny-Scheerer Co, It consisted of a copper boiler nickeled inside and out and provided with a water gauge, safety valve, thermometer, and exit tubes for the gas evolved. Heat was produced by a triple "Piis- Hius " oil burner. The apparatus was connected "with the disinfecting chamber by a rubber tube which connected with a small iron pipe entering the chamber at the top. The formaldehyde was generated from a mixture of Kny- Scheerer formalin 38.7 per cent of CHoO. The mixture was made u]) as follows : Formalin 1,350 c. c. Calcium chloride (anhydrous) 200 grs. Water to make up to 4,000 c. c. ASEPSIS AND ANTISEPSIS IN SURGERY. 167 The determination of formaldehyde was made by the ammonia method as given by Struver (Zeit. f. Hyg., Bd. XXV, Heft 2). -, . T V ^ 1. 1. +1. All determinations were made m duplicate by botn gravimetric and volumetric methods. It would have_ been advisable to determine the amount of mythyl alcohol m the formalin, as this reacts with formaldehyde at the tempera- ture of the operation, giving methylal, a substance havmg little or no disinfecting action. Any methyl alcohol pres- ent therefore, diminishes the efficiency of the iormahn. No' satisfactory method of determining methyl alcohol m such a mixture has yet been devised, and the results ot this experiment are therefore subject to a correction on this account. We have been assured by the manuiacturer of the formalin used, however, that it contains less than one per cent of methyl alcohol, and no serious error wdl be made by neglecting it. -, n • ^ ^ Silk threads were soaked for several hours m twenty- four-hour cultures of the bacteria used, and dried at room temperatures. These threads were then inclosed m sterile filter-paper envelopes as in the previous experiment, and were aiTanged as shown in Table 2, which also shows the result of the experiment.

The doors were then tightly closed and 12 168 ELECTRO-H^MOSTASIS IN OPERATIVE SURGERY. the vacuum pump started, and steam turned into the outer jacket in order to heat the inner chamber. In thirty minutes a vacuum of 14.25 inches was obtained, and the temperature of the inner chamber was then 40*^ C. In the meantime the lamp under the autoclave had been lighted, and the pressure raised to 37.5 pounds. The valves were then opened and the formaldehyde gas admitted to the chamber, the pressure of the autoclave being kept above 30 pounds. The gas was allowed to flow thirty minutes and was then shut off, the vacuum in the chamber having fallen to 10 inches and the temperature risen to 49° C. Air was then admitted to the chamber through the safety valve until the vacuum was reduced to zero. The temper- ature of the inner chamber was then raised to 65° C. and kept there during the rest of the experiment, which lasted altogether an hour and a half. At the expiration of this time the chamber was opened, the threads in the enve- lopes were removed and taken to the laboratory, where they were planted in sterile broth and incubated for a week. No moist cultures were used, as it was intended to make the experiment correspond as closely as possible to actual working conditions, and in practice we are seldom called upon to disinfect articles that are not dry. The for- malin mixture remaining in the autoclave was carefully removed and measured. It amounted to 2,300 c. c. and con- tained 9.27 per cent of formaldehyde, corresponding to 213.2 grammes. As the original mixture contained 500 grammes 286.8 were present in the chamber, and as the capacity of the chamber is 10,188 cubic metres, each cubic metre contains 28.11 grammes of CHgO. This corresponds to a volume per cent of 1.93, or, in round numbers, two per cent. This experiment proves that, under the conditions adoped, two per cent is sufficient to disinfect anthrax spores in the middle of a mattress — a very severe test — and, on this account, it is recommended that two per cent be the minimum of gas allowed. As regards the temper- ature and the vacuum, the experiment shows that a temper- ature of 65° C. is high enough, and that a vacuum of at least half an atmosphere is desirable. It will be seen that the temperature exercises a marked effect on the disinfection, and the failure of the first experi- ASEPSIS AND ANTISEPSIS IN SURGERY. 159 ment, where a much larger percentage of gas was used, must be attributed to the low temperature at which it was conducted. This method, therefore, gives a convenient and satisfac- tory disinfection of goods that would certainly be injured, if not ruined, by the use of steam. The advantages of the autoclave over the lamps are at once apparent : First. It produces a large volume of the gas. Second. Rapidity of application. Third. It is constantly under observation and located outside the room. Fourth. No damage to disinfected goods. CLEANLINESS IN THE CARE OF PATIENTS AND SICK ROOMS The older methods of disposing of soiled clothing, dressings, and discharges were most objectionable. Old foul dressings were carried from the halls, some of them to the laundry, to be washed and used again. Excrements were carried in open vessels to the closets, deposited tbere, and in the best-regulated hospitals or homes some disinfectant poured down the closet every time it was used, or several times a day, and the results were easily to be imagined. The methods pursued at the present time in my practice are to place all soiled dressings directly on their removal into a vessel. The vessel is closed witli an air-tight rubber cover and taken away and the dressings at once cremated. The vessel is disinfected at once, and made ready for further use. Vessels used for the reception of excrement, urinals included, receive before using some disinfectant and deodorizer, and when used are covered with air-tight rubber covers and taken away. Wash basins are emptied into slop pails that can be closed with rubber covers while conveying them to the closets to be emptied and cleansed. Bed linen is placed in a clean bag of rubber cloth and conveyed to the laundry. In this way the halls, stairways, and elevator are kept free from contamination and mal- odors.
