本文30例腭裂手术患儿麻醉恢复过程中的观察结果显示,随着麻醉变浅,EEG-BIS逐渐上升,两者间有明显的直线相关关系。当EEG-BIS为75时,有70%(21/30)的患儿出现吞咽反射;EEG-BIS为80时,80%(24/30)的患儿已出现肢体运动;EEG-BIS为90时,患儿多已有应答反应;EEG-BIS达到90以上,基本可拔除气管导管;EEG-BIS上升至95时,绝大部分患儿已恢复定向力,可安全返回病房。麻醉恢复期内,T和SpO2变化不大,T处于36.5-38.0℃的范围,SpO2保持在98%以上,无低温、缺氧的表现,拔管时MAP虽一过性升高至14.2kPa,但这种变化未发现对大脑造成缺血性影响。由此可见,EEG-BIS的监测基本上没有受到这些干扰因素的影响。
