摘　　要：目的探讨不同浓度罗哌卡因经蛛网膜下腔阻滞应用于剖宫产手术的麻醉效果。方法选取我院2016年1月~2017年2月行剖宫产手术的120例产妇作为研究对象,依据处理方法差异分为高浓度组(0.5%)和低浓度组(0.375%),每组各60例。高浓度组产妇采用高浓度罗哌卡因经蛛网膜下腔阻滞,低浓度组产妇采用低浓度罗哌卡因经蛛网膜下腔阻滞。比较两组产妇的麻醉效果、运动阻滞起效及持续时间、感觉阻滞起效及持续时间和不良反应发生率。结果两组产妇的麻醉效果比较,差异无统计学意义(P>0.05);两组产妇的运动阻滞起效时间、感觉阻滞起效时间比较,差异无统计学意义(P>0.05);而低浓度组产妇的运动阻滞持续时间、感觉阻滞持续时间短于高浓度组,差异有统计学意义(P<0.05)。低浓度组产妇的不良反应低于高浓度组,差异有统计学意义(P<0.05)。结论低浓度罗哌卡因经蛛网膜下腔阻滞应用于剖宫产手术的麻醉效果和高浓度无显著差异,虽然阻滞持续时间较短,但不良反应少,安全性高,值得推广。Objective To explore the anesthetic effect of Ropivacaine at different concentrations by subarachnoid block in cesarean section.Methods From January 2016 to February 2017,120 pregnant women undergone cesarean section were enrolled as research objects.According to the different therapeutic methods,the patients were evenly divided into high concentration group （0.5%） and low concentration group （0.375%）,60 cases in each group.In the high concentration group,Ropivacaine in a high concentration via subarachnoid block was used,while in the low concentration group,a low concentration Ropivacaine via subarachnoid block was adopted.The anesthetic effect,the onset time and sustained time of motor block,the onset time and sustained time of sensory block,and incidence of adverse reaction in the two groups were compared.Results The anesthetic effects were compared between the two groups,the differences were not significant （P〉0.05）.The the onset time of motor block and sensory block were compared between the two groups,the differences were not significant （P〉0.05）.However,the sustained time of motor block and sensory block in the low concentration group was shorter than those in the high concentration group,the differences were statistically significant （P〈0.05）. The incidence of adverse reactions in the low concentration group was less than that in the high concentration group,the difference was statistically significant （P〈0.05）.Conclusion There is no significant difference in the anesthetic effect between low and high concentrations of Ropivacaine in the treatment of cesarean section by subaraehnoid block.Although the sustained time of block is short,the adverse reactions are few and the safety is high,which is worthy of promotion.
