异丙酚全凭静脉麻醉苏醒期：全身麻醉的苏醒是个被动过程，取决于麻醉药的用量、麻醉药的作用
部位、麻醉效能和药代动力学、患儿的生理机能状态、以及手术的类型和持续时间。苏醒期的EEG模
式以与维持阶段大致相反的方式进行，在响应性恢复之前，alpha波能量减少，峰值频率增加 （24） 。

小儿采用TIVA麻醉时，应根据患儿年龄选择对应的输注模式，注意检查载液速度和输注泵，采用
防溢出和防返流管路通道等，以确保麻醉药物准确无误地输入患儿体内。掌握EEG波形分析为主导的
脑电监测较采用数值作为麻醉深度参考指标更精准。对小儿麻醉医生进行短期脑电分析培训，或许能
使小儿麻醉医生获益：实时判断小儿对麻醉药物的反应，避免麻醉过深过浅等并发症，保障小儿安
全，实现小儿精准麻醉。
