摘要 选择择期行下肢手术的病人80例,ASA I^III级,随机分为两组。对照组(n=40)0.5%的重比重罗哌卡因(罗哌卡因1.5ml1%+10%葡萄糖1.5ml)+0.5ml的生理盐水,右美托咪定组(n=40)0.5%的重比重罗哌卡因(罗哌卡因1.5ml1%+10%葡萄糖1.5ml)+5μg右美托咪定(0.5ml)行蛛网膜下腔阻滞。观察记录麻醉效果、不良反应以及术后镇静评分和VAS评分的差异。结果与对照组相比,右美托咪定组阻滞平面消退时间显著延长,术后VAS最高评分显著下降,差异具有统计学意义。(P<0.05)。两组间最高阻滞平面、平面固定时间、不良反应以及镇静评分无显著差异。5μg右美托咪定可以显著延长重比重罗哌卡因的痛觉神经阻滞时间,有利于延长患者术后镇痛时间并且不增加不良反应。
