摘要 目的观察0.75%罗哌卡因+舒芬太尼对老年人蛛网膜下腔阻滞效应的影响。方法40例65岁以上择期行下腹部以下手术的老年患者随机分两组:Ⅰ组(n=20)罗哌卡因15mg,Ⅱ组(n=20)罗哌卡因15mg+舒芬太尼5μg。观察腰麻注药后麻醉起效时间以及0,2.5,5,7.5,10,12.5,15,20,25,30min的痛觉减退平面和痛觉消失平面、镇痛向头延伸时间和向尾延伸时间、运动阻滞起效时间、达最大运动阻滞时间、Browage评分、T12处镇痛时间、镇痛总时间和运动阻滞持续时间、SBP,DBP,MAP,HR,RR,SpO2等指标以及腰麻后出现的副作用。结果各组SBP,DBP,MAP,HR,RR,SpO2等均无显著变化(P>0.05),麻醉起效时间、镇痛向尾延伸时间、痛觉减退平面和痛觉消失平面、运动阻滞起效时间、达最大运动阻滞时间、运动阻滞持续时间均相似。T12处镇痛时间、镇痛总时间,镇痛向头延伸时间Ⅱ组(Ⅰ组(P<0.01)。结论0.75%罗哌卡因+舒芬太尼用于老年人蛛网膜下腔阻滞安全、有效,5μg的舒芬太尼可增强罗哌卡因15mg蛛网膜下腔阻滞麻醉效果且对血流动力学无影响。
