It was by far the most difficult general anaesthetic to administer, because of the following reasons: i. The physical properties of nitrous oxide were such that this gas must be given from eighty to ninety per cent, pure, in order that a sufficient saturation of the blood might be had to produce that change in the nerve cell which brought about the anaesthetic state. 2. The anaesthetic properties of nitrous oxide and oxy- gen were extremely evanescent. The .patient could pass from complete surgical anaesthesia to a con- scious state within sixty seconds. The extreme rapidity of induction and elimination made the ad- ministration of this anaesthetic difficult. 3. Muscu- lar tone was maintained to a much greater extent than it was under ether or chloroform, due proba- bly to an increased per cent, of carbon dioxide in the blood. The requirements for the proper administration of nitrous oxide and oxygen were: i. A thorough understanding of the technique of administration and action of nitrous oxide and oxygen. 2. The apparatus must be accurate, have attachments for the administration of other general auccsthetic agents, and be easily sterilized. Dr. Bremerman stated that in his special work. which dealt entirely with the bladder, ureters, and kidney, or conditions involving the genitnirinary tract, he had employed as a general anaesthetic a combination of nitrous oxide gas and oxygen exclu- sively during the last two or three years. As it be- came necessary to perform major surgical opera- tions upon the aged, particularly for the removal of the prostate, he could not recommend more highly any other anaesthetic. It produced none of the un- toward after effects, such as nau>ea and vomiting. The patient was usually awake before he left the operating room. It Buy Intagra had a great tendency to reduce the shock of the operation by shc^rtening the length of the anesthesia, and in his bancs it had given per- fect satisfaction. Dr. Fenton B. Turck, of Chicago, stated some vears ago he conducted a series of experiments on October 29, 19 10.] PROCEEDINGS OF SOCIETIES. 889 animals with chloroform and ether with a view Intagra 100 of determining the changes that occurred in the blood. It was found by these experiments that there was a loss in the antibodies and ferments in the blood, and that there was diminished resistance to bacteria, as was shown by the agglutinins, precipitins, and other substances which were found in the antibodies in the blood. It was found that those animals went into shock very easily in which there was a lowered con- dition of the blood. These experiments showed the effects of ether and chloroform on the serum itself, and two conclusions were arrived at, one being that there was an actual direct chemical effect on the serum, and the other was that biological changes took place and acted on the cells as toxines. Acetabular Fracture with Intrapelvic or Cen- tral Dislocation of the Femoral Head. — Dr. William Fuller, of Chicago, detailed two cases of this class of fracture and presented for consideration a few points in a general way pertaining to this im- portant but, as yet, imperfectly understood subject. So close was the relation between fractures and the changes that took place in the bone, whatever they might be, that all such injuries resulting from trivial or slight degrees of violence should be regarded as possibly belonging to this class. Efforts had been made by several observers to put the aetiology of fractures on a physical basis by studying the me- chanical capabilities of bone. The great strength of the pelvic bones, their peculiar and powerful articu- lations, and liberal muscular supply were factors which, singly and combined, contributed much to the neutralization of all forms of direct violence ex- erted on this portion of the body. While Katz's theory of the mechanism of certain acetabular frac- tures would probably hold good, it was also worthy of mention that the experiments of Kusmin's demon- strated that this fracture could or would not occur unless the force was applied with the femur in ab- duction. When the legs were kept parallel the acet- abulum remained unfractured. From impacted fractures of the femoral neck cen- tral dislocation of the femoral head might be distin- guished by the age of the patient and the compara- tively high degree of injury in the latter instance.
