Aseptic Surgery.--The utility of the aseptic principle in surgery was demonstrated by the Japanese army surgeons during the war with Russia in 1904-1905. Their success in preventing deaths from suppurating wounds amazed the world. Their method was to discard the use of antiseptics and to depend upon absolutely clean instruments, dressings and hands. The most terrible wounds healed under this method without festering. This is, of course, the method in vogue to-day all over the civilized world. The Japanese did not discover aseptic surgery, but they were the first to put it to actual test in a large way. The old method was to depend upon drugs to kill the germs which might find their way into wounds and operations. To-day we prevent the germs from getting into the wound and depend upon nature to do the rest. New Anesthetics.--Several important advances have been made in methods of giving anesthetics and in the nature of the products used. Temporary unconsciousness with electricity was induced in 1909 by Dr. Stephane Leduc. Stovaine was invented by Dr. Jonnesco, of Bucharest. He injected it into the spinal cord after the method made famous by Biers with cocaine in 1899. Dr. W. S. Schley invented novocaine for the same purpose. Temporary unconsciousness was accomplished by the use of epsom salts injected into the spinal cord by Dr. Samuel J. Meltzer. All of these efforts to discover a harmless anesthetic by spinal injection were made possible by investigations and experiments of Dr. J. Leonard Corning, of New York, who worked along this line as far back as 1885. The most revolutionary discovery, however, was that of Dr. S. J. Meltzer at the Rockefeller Institute, New York, when he inserted a tube into the windpipe, through which he pumped the anesthetic into the lungs. While doing this he at the same time pumped oxygen to aerate the blood, thus ensuring the patient against possible accident during the course of difficult and tedious operations on the lungs and heart.
