Twenty-two children aged 5 to 15 years were examined. Ten children underwent fluorothane; 12 received a combination of sevofluorane and isofluorane. EEG was continuously recorded by a 9-channel computer-assisted encephalograph via bilateral electrode placement and BIS values were simultaneously measured. In the fluorothane group, EEG displayed a gradual reduction in basic rhythm, an increase in slow activity with the rhythm being recovered on emergence. The BIS index changed from 95-98 to 40-45 with a spike up to 78-84 on emergence. In the sevofluorane group, EEG recorded a pointed alpha rhythm, increased amplitude, and rhythm synchronization. The isofluorane anesthesia stage changed EEC patterns towards a reduction in cortical rhythm with slow fluctuations. The BIS value changed from 96-99 to 19-25 with 35-40 on anesthesia maintenance and up to 82-87 on emergence. The BIS data agree with EEG readings at all anesthesia stages.
对22名5至15岁的儿童进行了检查。10名儿童接受氟烷麻醉；12名儿童接受七氟烷和异氟烷的联合麻醉。通过双侧电极放置，使用9通道计算机辅助脑电图仪连续记录脑电图，并同时测量脑电双频指数（BIS）值。在氟烷组中，脑电图显示基本节律逐渐减慢，慢波活动增加，在苏醒时节律恢复。BIS指数从95 - 98降至40 - 45，苏醒时峰值高达78 - 84。在七氟烷组中，脑电图记录到尖锐的α节律、振幅增加和节律同步。异氟烷麻醉阶段使脑电图模式向皮质节律减慢波动转变。BIS值从96 - 99降至19 - 25，麻醉维持期为35 - 40，苏醒时高达82 - 87。BIS数据在所有麻醉阶段均与脑电图读数一致。
