title: [New study on the history of anesthesiology--(9) a brief history of "N2O Study Society"].
abstract: In Japan nitrous oxide has been manufactured since 1955 at the request of General Headquarters of the Allied Forces. Two years later in 1957, a manufacturer built a small society for the study and popularization of nitrous oxide anesthesia as well as general anesthesia. The society gave more than twenty seminars for this purpose in various cities in a period of 8 years from 1957 until 1965. At the seminars, Prof. Yamamura of Tokyo University and other professors of anesthesiology gave their lectures on basic science of nitrous oxide anesthesia and demonstrated its use for surgical patients. In July 1962, a fatal accident of explosion during ether anesthesia occurred in a hospital in Tokyo, in which a 25-year-old male died due to combustion and explosion triggered by electrical cauterization during surgery of pulmonary empyema. This accident facilitated and accelerated rapid and wide spread of nitrous oxide anesthesia as well as anesthesiology in general in Japan.
