The purpose of this study was to determine the relative incidence of infections of the respiratory tract after inhalation anesthesia and after spinal anesthesia in patients who had not had preoperative infections of the respiratory tract and who had undergone the same types of abdominal operations.
Since 1901 a copious literature has accumulated concerning postoperative complications involving the respiratory tract. An examination of this literature revealed that there was no previous report comparing the rates of occurrence of such complications in controlled groups of patients who had been subjected to the same abdominal operative procedures under ether, cyclopropane and spinal anesthesia.
MATERIAL AND METHOD
The material consisted of 631 cases in which abdominal operations were performed in the surgical service at Duke Hospital between the years 1930 and 1941. The operations included 245 appendectomies, 216 inguinal herniorrhaphies and 170 operations on the biliary tract, of which 166 were cholecystectomies. The
