The uptake of enflurane at a constant end-expired concentration of 2% in oxygen was studied in 38 patients, ASA 1 or 2, undergoing elective orthopaedic procedures. The anaesthetic was administered using a computer-controlled closed circle system. Following an initial 4 min period during which the expired concentration of enflurane was established, the rate of uptake of enflurane showed a triexponential decline. The mean cumulative use of enflurane after 60 min was 10.7 ml, and after 120 min was 18.4 ml.
在38例接受择期骨科手术的ASA 1或2级患者中,研究了在氧气中终末呼气浓度恒定为2%时安氟醚的摄取情况。使用计算机控制的闭环系统给予麻醉。在最初4分钟确定安氟醚呼气浓度后,安氟醚的摄取速率呈三指数下降。60分钟后安氟醚的平均累积用量为10.7毫升,120分钟后为18.4毫升。
