General anaesthesia was maintained in 22 patients undergoing major surgery using a proportional-plus-integral control system. The system automatically adjusted the dose of enflurane according to the systolic arterial pressure (SAP). Additional morphine was administered if the system's demand for enflurane exceeded preset limits. In 21 patients, satisfactory control of SAP was achieved and anaesthesia was clinically adequate; no awareness was reported and the mean recovery time was 6.7 min (SD 3.5 min).
使用比例积分控制系统对22例接受大手术的患者维持全身麻醉。该系统根据动脉收缩压（SAP）自动调整恩氟烷剂量。如果系统对恩氟烷的需求量超过预设限度，则追加吗啡。21例患者的SAP得到满意控制，麻醉临床效果良好；未报告术中知晓情况，平均恢复时间为6.7分钟（标准差3.5分钟）。
