Anesthesiology. This is the new term adopted by the University of Illinois defining "the science that treats of the means and methods of producing in man or animal various degrees of insensibility with or without hypnosis." [Medical Herald, January, 1912]
麻醉學。這是伊利諾伊大學採用的新術語,定義爲“處理在人或動物身上產生不同程度的無感覺狀態的手段和方法的科學,有或沒有催眠。”[《醫學先驅報》,1912年1月]
