罗哌卡因腰椎-硬膜外联合麻醉用于剖宫产术的临床观察

目的:研究罗哌卡因重比重配制液腰椎-硬膜外联合麻醉用于剖宫产手术的可行性、安全性和有效性。方法:将在腰椎-硬膜外联合麻醉剖宫产术中60例初产妇,随机双盲分为R组和B组,R组用0.75%罗哌卡因2 ml加入10%葡萄糖1 ml,B组用0.75%布比卡因2 ml加入10%葡萄糖1 ml,L_2~3间隙穿刺成功后以25 s速度蛛网膜下腔注药2.5~3.0 ml,硬膜外置管3.5 cm后取平卧,左倾15°。比较2组的感觉、运动阻滞的起效时间,最高阻滞平面及感觉、运动阻滞恢复时间,评估2组麻醉效果。结果:最高阻滞平面R组低于B组,从注药到最高平面阻滞时间R组明显长于B组,R组感觉和运动神经阻滞起效时间亦长于B组,下肢运动神经阻滞程度、Bromage评分R组低于B组(P<0.05~P<0.01),运动阻滞恢复时间R组短于B组(P<0.05~P<0.01),感觉阻滞恢复时间,新生儿Apgar评分及血氧饱和度(SpO₂)2组差异无统计学意义(P>0.05)。结论:重比重罗哌卡因腰椎-硬膜外联合麻醉用于剖宫产术是安全有效的。

Clinical effect of ropivacaine on combined spinal epidural anesthesia in cesarean section

Objective:To compare the feasibility,safety and efficacy of hyperbaric ropivacaine in combined spinal epidural anesthesia(CSEA) for cesarean section.Methods:In a randomized double-blind investigation,sixty primiparas undergoing elective cesarean section delivery CSEA were enrolled.The parturients were randomly divided into:group R and group B,30 cases in each.The parturients in group R were administered with 0.75% ropivacaine 2 ml diluted with 10% glucose 1 ml;others in group B were administered with 0.75% ...
