1、右江医学2014年第42卷第1期YoujiangMedicalJournal2014,Vo1.42No.1靶控输注瑞芬太尼抑制哈尼族患者气管插管及切皮反应的半数有效血浆浓度税昌中(云南省红河州第一人民医院麻醉科,蒙自661199)【摘要】目的探讨哈尼族患者复合异丙酚时,血浆靶控输注瑞芬太尼抑制气管插管及切皮反应的半数有效血浆浓度(ECs。)。方法择期手术患者5O例,靶控输注异丙酚(3.0/xg/m1)及瑞芬太尼(2.6ng/m1),患者意识消失(睫毛反射消失和对言语指令无反应)时静注阿曲库铵,待血浆靶控浓度(Cp)与效应室浓度(ce
2、)达平衡,BIS值为4O~5O时行气管插管。瑞芬太尼Cp按序贯法确定,浓度梯度为0.5ng/ml。结果采用半数效量序贯法公式计算患者复合异丙酚时,血浆靶控输注瑞芬太尼抑制气管插管的EC。为3.09ng/ml,95可信区间(CI)为2.05~4.13ng/ml,抑制切皮反应的EC。为3.24ng/mI,95可信区间(CI)为2.2O~4.27ng/ml。结论血浆靶控输注异丙酚3.0g/ml时,瑞芬太尼抑制哈尼族患者气管插管的EC。为3.09ng/ml,抑制切皮反应的EC。为3.24ng/ml。【关键词】哈尼族;哌啶类;二异丙酚;药物释
