Wakefulness during general anaesthesia was assessed by the isolated forearm technique in two groups of patients for Caesarean section. The anaesthetic was based on the use of oxygen 66%, nitrous oxide 33% and halothane 0.4% during the induction delivery interval. There was a highly significant reduction in wakefulness in the Group who received nitrous oxide at 66% for the first 3 min only. The wakefulness was amnesic in all cases.
采用孤立前臂技术对两组剖宫产患者全身麻醉期间的清醒状态进行评估。诱导分娩期间，麻醉采用66%的氧气、33%的氧化亚氮和0.4%的氟烷。仅在最初3分钟给予66%氧化亚氮的组中，清醒状态显著降低。所有病例的清醒状态均伴有遗忘。
