Septicemia and its Treatment with Oxygen BY ANDREW F. CURRIER, M.D. • New York RBPR1HTBO FROM The American Journal of Obstetrics Vol. XXVII., No. 6,1803 NEW YORK WILLIAM WOOD & COMPANY, PUBLISHERS 1893 SEPTICEMIA AND ITS TREATMENT WITH OXYGEN.1 There is scarcely a physician, whatever his line of practice may be, who is not brought into more or less intimate contact with septicemia. Perhaps there is no disease from which phy- sicians suffer so frequently in their own persons. Its treatment is consequently a matter of unusual importance, whether it be regarded from the prophylactic standpoint or include the con- sideration of measures for attacking it when actually present. The disease has many varieties, or perhaps it is better to say grades of intensity, and I shall only attempt to consider, at least in the main, those of its forms and phenomena with which the gynecologist and the obstetrician are apt to be confronted. It is only since the development of bacteriological science that our knowledge of the etiology of this disease has been definite. Upon bacteriological investigation we must also depend, to a greater or less degree, for the settlement of questions concern- ing its prognosis and treatment. Notwithstanding these facts, the part which the clinician has to play in this disease always will be an important one, perhaps the most important. Fundamental to the consideration of this subject are the fol- lowing facts: The blood is the vehicle by which noxious as well as nutritious elements are carried to all parts of the body. The blood, in the infectious diseases, contains injurious elements which are clearly demonstrable, and their injurious ef- fects are also susceptible of demonstration. The virulent effect of these elements varies under different conditions, according as their number and vitality are small or large, and, with refer- ence to the individual, according as his resisting power is great orsmall; it being understood that different individuals differ in their resisting power, and that the same individual offers 1 Read at the annual meeting of the American Gynecological Society, Philadelphia, May 16th, 1893. 2 CURRIER SFPTICEMIA AND ITS greater resisting power at one time than another. These pre- liminary considerations are of importance, for they explain the varying intensities of septicemia and the varying effects of thera- peutic agents and measures at different periods even upon the same individual. In Keelson's classification 1 septicemia is de- fined as a toxic acute mycosis of the blood. Or, in plainer Eng- lish, it is a condition of the blood in which poisonous effects are produced more or less rapidly and intensely by germs which it contains, the germs having entered the body from without as elements foreign to it or as normal parasites of the body, and, comparatively harmless under ordinary conditions, have under- gone changes which have made them a source of injury. These statements presuppose the fact that the normal blood of healthy animals does not tolerate pathogenic organisms; that when they are present it tries to get rid of tliem. The pro- cess of phagocytosis is the chief means of disposing of them and effecting a cure,2 but when this process is defective for any cause, or when the vital forces of the body are feeble in their resistance or the pathogenic organisms especially active, the symptoms of septicemia are apparent. The present pathology of septicemia seems to rest upon foundations which are firm. The experimental portion of the evidence upon which it rests appeals strongly to the convictions even of those who are with- out practical experience in bacteriology, and may fairly be ad- duced as argument by such. Some of that evidence is as fol- lows : In rabbits fatal septicemia may be produced in eight days by injections of the Microbacterium agile of Davaine.3 In house mice septicemia may be induced by injections of Koch's bacillus of septicemia or the putrefying fluids which contain it. The symptoms produced are considered characteristic of the disease, and the bacilli themselves may be found in the leu- cocytes and subcutaneous tissue about the seat of inoculation and in the blood vessels. Rabbits and guinea-pigs may also be infected by similar means, but not to the same extent.4 Injec- tion of a few drops of a culture fluid of Bacillus pyogenes feti- dus will induce septicemia in mice and guinea-pigs.5 1 See Parke, " Miitter Lectures," 1892, p. 27. 2 Arloing, " Les Virus," 1891, p. 203. 3 Arloing, 1. c., p. 130. 4 Delafield and Prudden, "Handbook of Pathological Anatomy and His- tology," 1889, p. 89. 5 Parke, 1. c., p. 81. TREATMENT WITH OXYGEN. 3 Yet more convincing are the experiments of Garre, Bumm, Bockhardt, and Schimmelbusch, because performed upon them- selves. Garre produced phlegmons on his arm from injections of a pure culture of Staphylococcus pyogenes aureus of the third generation, the phenomena of the disease continuing several weeks. Schimmelbusch found that the bacteria, when rubbed into the unbroken skin, penetrated the hair follicles, prolife- rated and then infected the tissues. In Bumm's experiments abscesses were produced, and the abscesses contained large num- bers of Staphylococcus pyogenes aureus, with cultures of which the experiments had been performed.1 Evidence of another character is furnished by Escherich, who examined milk ob- tained from the breasts of thirteen women who were suffering- with puerperal fever. In none of the cases was there excoria- tion of the nipple or glandular abscess. From ten of the speci- mens staphylococci were obtained from the secretions of both breasts, and from one from the secretion of one breast. In these cases it was believed, and on evidence which seems to be perfectly trustworthy, that the organisms entered the blood by way of the uterus and were excreted with the milk. Bacteria in the lochia of women suffering with puerperal fever were found by Mayerhofer. Coze and Feltz. investigating the same disease in 1869. found punctiform bodies, solitary or in chains, in the blood and secretions. Injections of solutions of these substances into the bodies of healthy animals resulted in evidences of infection. Further investigations in this disease were made by Chauveau in 1882, and puerperal fever was re- produced in animals with the first two generations of cultures of the isolated microbes. In 1883 Arloing showed that the virulent microbe in puerperal fever could be reproduced with its morphological and pathogenic characters in almost an indefi- nite series in a medium of beef tea. The same conclusions were readied by Frankel, at about the same time, with cultiva- tions upon gelatin.2 The following interesting experience of Eiselsberg is quoted by Parke:3 In four cases of fever following injury and opera- tion a diagnosis of septicemia was made by means of a bacterio- logical examination of the blood. Acute rheumatism was known 1 Parke, 1. c., p. 73. 2 The foregoing quotations from Arloing, 1. c., p. 35 et seq. 3 Loc. cit., p. 43. 4 CURRIER : SEPTICEMIA AND ITS to be present in one of them, but the bacteriological examina- tion showed that there was also osteomyelitis. In three of the cases the blood contained staphylococci, in the fourth strepto- cocci. In eight other cases of septic disorder which were seen by Eiselsberg a correct diagnosis was reached by bacteriological examination. The microbes which are to be found in cases of septicemia are the streptococci1 and staphylococci, together with their sol- uble products.2 In the cases of so-called mixed infection other microbes are also to be found. Much attention has been paid during the past year to the Bacterium coli commune, which is ordinarily a harmless inhabitant of the intestine, but becomes pathogenic in the presence of decomposing matter in the intestine, as in cases of prolonged constipation. The forms of septicemia with which one necessarily becomes acquainted in the practice of gynecology and obstetrics may be the result of- 1. Decomposition of retained material in the intestines, with absorption of toxic products resulting therefrom. 2. Absorption of the products of retained and decomposed material following abortion or labor at term, through the uterine lymphatics or any divided portion of the uterine mucous mem- brane. 3. Intoxication associated with surgical procedures upon the abdominal and pelvic organs. The first of these varieties is very much more common than is generally believed. Women who suffer with constipation 1 The streptococcus has been found by Predohl and Frankel in cases of peritonitis (Parke, loc. cit., p. 130). The streptococcus and staphylococcus have been found by Bumm in puer- peral peritonitis. Bumm considers putrid peritonitis as usually the result of surgical procedures (Parke, loc. cit., p. 140). Babes considers ordinary puerperal fever as a streptococcus invasion, but the pyemia following abortion as the work of the staphylococcus (Parke, loc. cit., p. 72). It is hardly necessary to say that the terms puerperal fever, puerperal cel- lulitis, puerperal peritonitis, and puerperal septicemia all mean practically the same thing-that is, that poisonous effects have accompanied the puerperal condition as the result of infection. 2 Rodet and Courmont have found that the same results were to be obtained from the soluble products of staphylococci and streptococci as from cultures of the microbes (Arloing, loc. cit., p. 203). TREATMENT WITH OXYGEN. 5 which goes unrelieved for long periods of time, and who pre- sent the outward appearances of anemia and malaria, are very often simply victims of septicemia. Parke called attention to the influence of the Bacterium coli commune in such cases in the "Mutter Lectures" for 1892, and laid stress upon the import- ance of thoroughly clearing out the intestines prior to opera- tions in which the intestines might be directly or indirectly in- volved, thus anticipating harmful effects from the development of the bacterium. The second form of septicemia, in which there is decomposed material within the uterus, together with the toxic germs (strep- tococcus, staphylococcus) which develop and produce infection in such a medium, may present mild symptoms and be readily susceptible to treatment, or it may so overwhelm the entire organism that no treatment will be of the least benefit. Such cases are often extremely insidious, running a comparatively mild course for days or weeks while undermining the vital forces beyond the possibility of repair. The third form of septicemia with which this paper is con earned is usually attributed to some conscious or unconscious fault on the part of the surgeon ; to dirty hands or dirty instru- ments ; to the direct introduction of poisonous germs. This is but a half-truth, for we now know that a relatively clean opera- tion (absolute cleanliness being comparatively unattainable) in tissues that are unusually sensitive may result seriously. The individual equation eludes all attempts at antisepsis or asepsis. An antiseptic may be an irritant, and often provokes, in sen- sitive tissues, trouble which the laboratory experiment taught that it would prevent. A scrubbing brush may carry disease in its bristles, or it may be used so vigorously that the protecting epidermis will be removed and infection invited. The bruis- ing and tearing of tissues, their prolonged pressure or exposure, and the various faults in the use of the ligature are quite as influ- ential in the production of septicemia as the introduction of a few germs which it is the business of the blood cells, and par- ticularly of the peritoneum, with which most of the operations of the gynecologist are directly or indirectly concerned, to dis- pose of. The symptoms which more than any others mark the pre- sence of septicemia and demonstrate the pernicious effect of the toxic agent are referable to the nervous system. Such are tb@ 6 CURRIER : SEPTICEMIA AND ITS paralysis of the muscular coat of the intestine, uncontrollable vomiting, obtuseness of the intellect, or mental excitement with spasmodic movements of muscles or groups of muscles. Coin- cidental with these grave symptoms there may be the greatest activity in the eliminative organs-the skin, the kidneys, the in- testines, the lungs-as if Nature were making frantic efforts to get rid of the accumulating load. With favorable conditions for the development of the toxic germs within the body, the struggle is an unequal one. Okintchitz1 has found that the prognosis depends directly upon the number of the microbes, a great number of them rendering it unfavorable, even though there be no metastatic deposits. The object of treatment, there- fore, in cases in which the blood contains or is likely to con- tain such toxic elements as have been under consideration, is twofold-namely, to sustain the natural forces, so that in the struggle which we are told the healthy elements of the blood are constantly waging against the toxic the former may be vic- torious, and, in addition, to use if possible such means as shall directly destroy or neutralize the effect of the toxic elements. The natural forces are to be sustained by the greatest possible abundance of the most concentrated food substances, especially milk, and by an abundance of alcohol. A starvation diet is as inappropriate in the treatment of septicemia as in the treatment of typhoid fever and other wasting diseases. The role which is played by alcohol is probably identical with that which it exer- cises in the fevers. The tolerance which delicately organized women show for large quantities of alcohol in all these conditions is remarkable, and seems to indicate that its toxic effects are ex- pended in antidotal action upon some other poison. But I do not propose to argue at length upon the value of alcohol as a germicide at the present time, decided though I believe its value is, and conscious though 1 am that there are few substances which can so readily be brought in contact with the elements of the circulation. The object of this article is more particularly to direct attention to the availability and utility of oxygen as a means of treatment. The facility with which oxygen is ab- sorbed by the blood, the function of the hemoglobin in carrying it and distributing it to the tissues, and the oxidation which is accomplished through its affinity for nitrogen, hydrogen, and carbon, are fundamental physiological facts which require only 1 Parke, loc. cit., p. 78. TREATMENT WITH OXYGEN. 7 a passing notice. The capacity of the blood for absorbing oxy- gen is a more complex matter, for it involves consideration of the state of the blood at the time of treatment, the functional activity of the lungs, the tension of the gas, etc. For these reasons the experiments which have been made upon animals (Thompson, Valenzuela), and those which have been made by individuals in health upon themselves (A. H. Smith, Krafft), as to the influence of inhalations of oxygen, can- not furnish us with positive deductions as to what may be ex- pected when disease is present. I do not hesitate to say, how- ever, that they are of great value, and should be studied side by side with the clinical investigations, which, up to the present time, have not been numerous. The negative evidence of the value of oxygen consists in the distress which one feels when the supply is insufficient, and the anemia which is so common in the winter among those who are shut up more or less completely in over-heated and under-venti- lated houses. We are too apt to lose sight of the fact that in the ordinary sick-room, say twelve to fifteen feet square, with a pa- tient and one or more attendants, each of whom requires sixteen cubic centimetres of atmosphere per respiration, with a stove fire or hot air from a furnace, and with the combustion from lamps, gas, or candles, the windows being tightly closed, the con- ditions are not favorable for the patient who has to remain in the room all the time. The difference in results between a de- ficient and an abundant supply of oxygen is seen in the records of treatment of epidemics of typhus fever and other infectious diseases when the cases in one series are treated in hospital buildings and in another in tents. Another instructive fact is the comparative absence of septicemia among Indian puerperal women so long as they lead an out-of-door life; and the same is more or less true of all women who lead an out-of-door life. This also is indirect evidence, but nevertheless quite convincing. On the other hand, if it is not oxygen which guards against septicemia in such women, it is not cleanliness, that being un- known as it is understood in w'ell-appointed hospitals; and, again, when these people become partly civilized and live in houses they suffer with infectious diseases like other people. Dark blood, outside the body, which absorbs oxygen becomes decarbonated, bright-that is, arterial. The effect will be the same when it is diffused into the blood through the mucous 8 CURRIER : SEPTICEMIA AND ITS membrane of the lungs or alimentary tract. This suggests the very important question of tension and pressure in the use of oxygen. Atmospheric air being a mixture (O + 4N), one vol- ume of oxygen will contain the equivalent in oxygen of five volumes of air, and the pressure of one atmosphere of oxygen will give an equivalent in oxygen of five atmospheres of air. The effect of very high pressures (twenty or more atmospheres) is harmful, or even destructive, to the essential elements of the blood.1 A pressure of even three atmospheres produces convul- sions in rabbits (Thompson). It is evident, therefore, that some care should be exercised to prevent the irritating effect of exces- sive absorption of oxygen. The saturation of the hemoglobin is a variable term in every case. It can be approximately deter- mined for the blood in health, but in septicemia the corpuscles are small and many of them are disintegrated. The plasma, which in health contains but two per cent of the total volume of the oxygen of the body, will absorb somewhat more than this under pressure, and its increased volume of carbon dioxide, urea, and uric acid in septicemia will still further favor oxygen absorption and oxidation. Consequently the volume and pres- sure of oxygen which are appropriate in each case of septicemia must be determined by experiment in each case. The dark color of the blood, the small size and disorganized condition of many of the red globules in septicemia, and the shallowness of the respiration indicate a deficiency in the oxygen supply. The effect of an increase in the supply of oxygen in the blood upon the microbes of septicemia has not yet been definitely deter- mined. Dr. William II. Welch, of Baltimore, in a personal communication says: ''I do not think that it will be easy to explain the beneficial effects of inhalations of oxygen, which you have observed in cases of septicemia, by any known influ- ence of oxygen on the bacteria themselves. When bacteria are submitted to an atmosphere of oxygen under high pressure, some species are killed. Some kinds of bacteria die more quickly when exposed to oxygen than when the air is excluded, but this is generally a matter of days. The products of bac- terial growth are often of a very different nature when there is free admission of oxygen than when this is excluded. Then one has to consider whether a beneficial therapeutic agent which has ao apparent effect on the bacteria or their products may not 1 Arloing, " Les Virus," 1891, p. 99. TREATMENT WITH OXYGEN. 9 enable the animal organism to contend more successfully against the bacteria. The question, you see, is a complex one, but I do not think that you would be warranted in believing that the good results of your treatment are attributable directly to a germicidal influence of the oxygen on the bacteria themselves." The experiments of Grossmann and Mayerhauser,1 Pasteur,2 Chauveau,3 and Arloing4 simply confirm the statements of Welch that a positive germicidal effect of oxygen upon microbes circulating in the blood cannot as yet be demonstrated, at least under such conditions as would be compatible with the welfare of the rest of the organism.5 The beneficial influence of oxygen inhalation in septicemia probably depends, therefore, upon some other than a germicidal action. That which is noticeable when chemically pure oxygen is in- haled at such a pressure as is compatible with existing conditions of respiration is usually as follows : a stimulus to deeper respi- ration ; warmth of the extremities, perhaps warmth of the entire body ; increased tension of the pulse ; a more natural color of the surface of the body, if it has been dark or very pale.' If the discoloration of the surface were an evidence of sepsis, 1 Bacteria in general do not live more than twenty hours in oxygen at a ten- sion of five to seven atmospheres. * Culture fluids of the bacterium of chicken cholera are attenuated by ex- posure to atmospheric air. ' Attenuation of culture fluids of carbuncle bacteria results from exposure to oxygen under high tension. 4 A tension of five to eight atmospheres of oxygen will suspend microbic life in the interior of a culture, and then destroy it. Simple contact of oxygen at normal tension, if sufficiently prolonged, will weaken the virulence of cul- tures (Arloing, " Les Virus," p. 235). 6 With reference to the influence of the higher equivalences of oxygen. Welch writes : " Ozone and nascent oxygen are more powerful than ordinary oxygen in checking the growth of bacteria" (Medical Record, May, 1889). W. G. Thompson (Medical Record. May, 1889) says it is impossible to take ozone into the blood through the lungs, and that even if it were possible its presence would be incompatible with the normalJJcontinuance of the circulation. Oberdbrffer (Centralbl. fur Bakteriol. und Parasit., 1890, vii., p. 3-0) found that cultures of Staphylococcus pyogenes aureus were destroyed after half an hour of exposure to a stream of ozone which had been passed through a Babes' ozone tube, and concluded that ozone was unfavorable to the development of disease-producing micro organisms, also that the ozone in the blood, if in suffi- cient concentration, exercised a destructive influence upon micro organisms which were introduced therein. 6 Thompson says he has never seen a favorable change in the color of the surface when oxygen was inhaled by cyanotic individuals, nor incases in gene- ral in which there was heart disease. 10 CURRIER : SEPTICEMIA AND ITS improvement in this symptom is to be expected from the use of oxygen, provided it was used before intoxication had become too general.1 The stimulation of the blood current and of the respiratory function is, of course, directly favorable to the purification of the blood by elimination of its toxic elements. The stimulation of the nerve centres presiding over functional activity, which is possible if intoxication is not too pronounced, is apparently the effect of the oxygen, and this, if sufficient and continuous, will produce a favorable result whether there is direct germicidal ac- tion upon the bacteria in the blood or not. One of the most noteworthy symptoms attending this method of treatment is the drowsiness and sleep which are induced. I have observed the same thing when the windows of a sick-room were thrown open and a large volume of fresh air was intro- duced. The increased freedom of respiration, the warmth which suddenly diffuses through the entire body, the condition of bien aise which patients at once assume, are certainly suggestions that a powerful change is being wrought in the body, and if the ad- ministration of oxygen is begun sufficiently early-that is, before the centres of functions are paralyzed by the poisonous agencies- it would seem that much benefit could be expected from the use of this remedy. The only ill effect which I have ever seen con- sists in pain referred to the region of the stomach, which was probably due to swallowing the oxygen, which may have been administered under too great pressure. (I have observed this symptom in two cases, one a case of septicemia attending pro- longed retention of feces, and the other a case of mammitis fol- lowing labor at term.) With reference to the method of administering the oxygen, my experience leads me to believe that the simpler it is the more desirable will be the result. The principal precautions seem to me to be the determination that the oxygen is pure, that it be administered sufficiently early in the history of the disease, and that it be administered oidy in sufficient volume to be readily and comfortably tolerated. The histories of two cases are added, in one of which it was used successfully ; in the other it produced decided benefit at 1 A. H. Smith reports two cases of diphtheria cured by Beigel by this means and a case of pyemia of his own, also cured.

The two cases are given as types of what may be expected in the way of bene- fit from the gas, and of its limitations. Case I.-Mrs. F., German, age 48. Hegar's operation, Octo- ber 6th, 1890, for large myoma uteri. Operation very difficult on account of adhesions. Peritoneum torn in many places. Profound shock. Drainage tube two days. Bowels moved third day. Evidences of heart failure third day. Tincture of digitalis and tincture of strophanthus in ten-drop doses every two hours ; turpentine, muriate of iron, and carbonate of am- monia also used at sufficiently frequent intervals. Eighth day, urine contains albumin. Tenth day, abscess of abdominal wound discharging freely. Eleventh day, collapse ; pulse 150, temperature 103°, respiration 40, cyanosis. Atropia, morphia, whiskey, ammonia administered. Oxygen by inhalation at- tended with great relief to respiration and refreshing sleep. Acute nephritis developed, and oxygen inhalations were con- tinued during subsequent week. The oxygen was inhaled from five to ten minutes at a time, according to the urgency of the symptoms, and discontinued as the respirations became deeper and the skin natural in appearance. The patient ulti- mately made a complete recovery. It was believed that the oxygen repeatedly warded oft impending death. Case II.-Mrs. II., American, age 39. Operation for re- moval of dead and macerated fetus, January 11th, 1892. Sep- tic at time of operation. Uterine tissue very firm and dilated with great difficulty. Septic peritonitis quickly developed. Uterus irrigated frequently. Symptoms urgent, oxygen inha- lation on the fourth day, with immediate relief to dyspnea. Drowsiness and sleep, apparently due to the oxygen. Catarrhal gastritis very troublesome; delirium. Renal functions very ac- tive ; bowels thoroughly evacuated, fecal matter having been retained a long time. Sepsis became universal, without forma- tion of pus. Oxygen used at intervals for a week, and then for two days almost continuously. After the intoxication be- came general there was no decided benefit from the oxygen, except in a certain amount of relief to dyspnea. It may have delayed the fatal issue, which occurred on the twelfth day. The effect during the first few days was markedly beneficial, but evi- dently insufficient to stem the tide of advancing sepsis. 85 Madison avenue.
