摘要 目的:比较靶控输注异丙酚日间与夜间给药的镇静疗效,为合理使用异丙酚靶控输注疗法提供参考。方法:选取2015年4—10月间收治的行急诊手部小手术的患者49例,根据手术时间将患者分为日间组30例(07:01—19:00)和夜间组29例(19:01—07:00);两组患者均给予局部或臂丛神经阻滞治疗,待麻醉疗效起效后开始以阶梯给药的方式给予靶控输注异丙酚,设定的4个效应室,其靶控浓度分别为0.8,1.2,2.0和4.0μg/mL;当异丙酚效应室浓度达到预设值后,维持5 min,记录各浓度下患者的脑电双频指数(BIS)值,比较两组患者在不同时间段异丙酚效应室浓度下的BIS值,并给予警觉与镇静评分(OAA/S评分,记录分值为2分时异丙酚效应室的浓度和BIS值。结果:夜间组患者在基础状态、异丙酚效应室浓度分别为1.2μg/mL和2.0μg/mL时的BIS值明显低于日间组(P<0.05);两组患者在异丙酚效应室浓度为0.8μg/mL和4.0μg/mL时的BIS值经比较其差异无统计学意义(P>0.05);患者OAA/S评分值为2分时,夜间组的异丙酚效应室浓度为(67.8±1.9)μg/mL,低于日间组为73.2±1.8)μg/mL(P<0.05);两组患者的BIS值经比较其差异无统计学意义(P>0.05)。结论:异丙酚的夜间镇静疗效强于日间,提示昼夜节律可影响异丙酚的镇静疗效。
