摘要 目的 探讨体外循环大剂量芬太尼静吸复合麻醉对脑电图 (EEG)双频谱指数 (BIS)、听觉诱发电位指数 (AEP)等的影响。方法  10例低温停循环心脏手术患儿 ,设麻醉前、麻醉后、体外转流后等 9个监测点 ,观察体外循环大剂量芬太尼静吸复合麻醉下BIS、AEP的变化。结果 麻醉后与麻醉前相比BIS、AEP显著下降 (P <0 0 1) ,体外转流后与麻醉后相比明显下降 (P <0 .0 5) ,低温停循环后与转流后相比显著下降 (P <0 .0 1) ,低温恢复循环后与低温停循环后相比显著上升 (P <0 .0 1) ,心脏复跳后与低温恢复循环后相比明显上升 (P <0 .0 5)。体外循环期间保持血液稀释度 (Hct)在 0 .2 2± 0 .0 2 ,最低温度 (2 3± 2 .5)℃。结论 体外循环大剂量芬太尼静吸复合麻醉时BIS和AEP应分别调控在 60和 3 0左右。体外转流、血液稀释度。
