摘要:目的观察靶控输注异丙酚全凭静脉麻醉诱导及术中血流动力学变化、术后苏醒时间及相应的效应室浓度,以指导临床合理用药. 方法 ・L-1 ,复合咪唑安定2mg,芬太尼2μg・kg-1 ,・kg-1 气管插管,术中维持异丙酚浓度为2mg・L-1 ,记录诱导前、诱导后2min、插管即刻、插管后2min、切皮及气腹时心率(HR)、收缩压(SBP)、舒张压(DBP)、平均动脉压(MAP)及停药后苏醒时间,苏醒时相应的效应室浓度. 结果插管即刻HR,SBP,DBP及MAP均与诱导前比较有显著差异(P<),气腹后DBP,MAP也较诱导前有明显升高(P<),平均苏醒时间为(±)min,相应效应室浓度为(±)mg・L-1 . 结论采用靶控输注异丙酚全凭静脉麻醉诱导时和维持期血流动力学相对较为稳定,术后苏醒较为迅速.
