耳鼻咽喉科麻酔1,246例の統計的検討

Statistical Analysis of 1,246 Cases of General Anesthesia in Otolaryngic Surgeries

I．はじめに

　1965年（昭和40年）弘前大学医学部に麻酔科学教室が創設されて以来同学医学部付属病院で麻酔科が管理した全身麻酔の症例は1982年（昭和57年）末までの18年間で23,331例に達した。このうち耳鼻咽喉科の症例は1,916例で全症例の8.2％であった。

　従来全国各大学の麻酔科学教室から発麦された麻酔統計は年度別の麻酔症例数や麻酔方法の推移に関するものが主であった^1〜3）。

　During a period of eight years from 1975 to 1982, a total number of 1,216 cases of otolaryngic surgerieswas performed under various type of general anesthesia.

　We analysed these cases using a microcomputer (NEC, PC-9801) concerning the following factors such as sex, age, annual numbers of cases, cases of emergency operation, operation time, anesthetic time, fluids given, anesthetic method, muscle relaxants and complications.

　By this statistical study, it was concluded that neuroleptic anesthesia and enflurane anesthesia were most frequently employed as general anesthesia for ENT surgeries, because these permit us to use intraoperative electric instruments and administer local anesthetic with adrenaline.
