摘要 目的研究靶控输注(TCI)丙泊酚时舒芬太尼复合气管内表面麻醉,在无肌松药下诱导重症肌无力(MG)患者气管插管所需的半数有效浓度。方法拟行经胸骨正中劈开胸腺切除术的MG患者20例,ASAⅠ或Ⅱ级。麻醉诱导丙泊酚采用血浆浓度(cp)TCI,维持3.5μg/ml不变;舒芬太尼采用效应室浓度(Ce)TCI,按序贯法确定浓度,依次为0.15、0.23、0.34、0.50ng/ml等比递增,相邻效应室靶浓度之间比例为1.5。复合气管内表面麻醉后行气管插管。监测诱导、插管过程中的血压、心率和脑电双频指数(BIS)。结果50%患者完成插管时舒芬太尼的浓度为0.23ng/ml,95%的可信区间为0.20~0.27ng/ml。结论MG患者在不使用肌松药和复合气管内表面麻醉的情况下完成气管插管,丙泊酚血浆靶浓度为3.5μg/ml,舒芬太尼半数有效效应室靶浓度为0.23ng/ml。
