摘要 目的:探讨高海拔地区靶控输注(TCI)丙泊酚的药代动力学。方法:选择全凭静脉麻醉下实施择期全子宫切除术的患者120例,ASA(Ⅰ~Ⅱ)级,年龄(35~55)岁,中度高原地区组(海拔2 000m^3 000m,Ⅰ组)、平原地区组(海拔<200m,Ⅱ组),每组60例。两组均采用TCI方式输注丙泊酚。间断采集动脉血至用药后30min止,采用高效液相色谱法检测血浆丙泊酚浓度,经计算机软件拟合,得到各项药代动力学参数。结果:与对照组相比,中度高原地区组的清除率升高(P<0.05);两组间分布半衰期、消除半衰期、中央室分布容积及外周室分布容积比较无显著性差异(P>0.05)。结论:中度高原地区组患者丙泊酚清除率升高,在相同药物剂量时,可能不会出现药物蓄积和作用时间延长。
