摘要 目的 观察听觉诱发电位指数 (AAI)和脑电双频谱指数 (BIS)在急腹症全麻诱导期间的变化 ,评价其临床监测麻醉深度的价值。方法 选择急腹症手术且听力正常的病人 4 0例 (ASAⅠ~Ⅱ ) ,分别采用Mid -Fen -Ro(Ⅰ组 )和Mid -Fen-Pro -Ro(Ⅱ组 )顺序诱导。监测记录诱导前两组的基础值 (T0 )、静注Mid后 1min(T1)、静注Fen后 1min(T2 ) ,Ⅱ组静注Pro后1min(T3 )、静注Ro后 1minⅠ组 (T3 )和Ⅱ组 (T4) ,插管后 1minⅠ组 (T4)和Ⅱ组 (T5) ;上述各点的AAI、BIS、MAP和HR。结果 两组病人全麻诱导气管插管前均能达到满意的麻醉深度 ,但Ⅰ组气管插管后 (T4)MAP和HR均较T0 和插管前 (T3 )明显升高(P <0 0 0 1) ,插管前后比较AAI和BIS亦升高 ,以AAI变化尤为明显 ,较T3 值有显著差异 (P <0 0 0 1) ,病人处于有意识状态。Ⅱ组气管插管后 (T5)MAP和HR与T0 比较无差异 ,较插管前 (T4)升高 ,但不如Ⅰ组明显 ;AAI和BIS较T4升高 ,以AAI升高明显 ,但仍处于临床麻醉状态。结论 麻醉诱导期间AAI和BIS均能准确地反映临床麻醉镇静深度 ;咪唑安定和异丙酚联合使用能平稳地诱导麻醉且用药量小。
