摘要 为观察硫喷妥钠在混合液中对异丙酚药代动力学的影响,选择拟行神经外科手术病人24例,随机分成两组,每组12例。异丙酚组(P组):麻醉诱导用芬太尼(4μg/kg)、1%异丙酚2 mg/kg和罗库溴铵0.6 mg/kg;混合液组(T+P组):麻醉诱导用2.5%硫喷妥钠2.5 mg/kg和1%异丙酚1 mg/kg 1:1等体积混合液, 其余同P组。经足背静脉注射完诱导用药后,分别于给药后1、3、5、10、30、60、120、180及240 min抽取桡动脉血2 ml肝素抗凝,离心后取上层血浆于4℃冰箱中保存。采用高效液相色谱法检测异丙酚浓度,3P97药代动力学程序计算各药代动力学参数值。结果表明,P组与经校正后的T+P组各时点异丙酚血药浓度值相比差异无显著意义(P>0.05)。两组异丙酚血药浓度均符合三室开放模型,各药代动力学参数值比较差异均无显著意义(P>0.05)。结论:异丙酚与硫喷妥钠混合应用于麻醉诱导时,硫喷妥钠并不改变异丙酚的分布容积和清除率。
