不同浓度罗哌卡因用于剖宫产手术的临床观察

Clinical observation of different concentrations of ropivacaine for cesarean section

目的:不同浓度罗哌卡因腰硬联合麻醉用于剖宫产手术的临床观察。方法:将剖宫产术产妇90例分为A、B两组给予腰硬联合麻醉。A组45例,向蛛网膜下腔注射0.5%罗哌卡因2.1 mL;B组45例,向蛛网膜下腔注射0.375%罗哌卡因2.8 mL。分别观察两组麻醉效果。结果:A组患者麻醉前、后的心率、血压变化差异有统计学意义(P<0.05);A组运动阻滞持续时间长于B组,差异有统计学意义(P<0.05);A组麻黄碱使用量多于B组,差异有统计学意义(P<0.05)。结论:等效0.375%罗哌卡因用于腰麻对下肢运动神经阻滞更轻、恢复更快,血流动力学更稳定。

Objective:To observe the clinical effect of different concentrations of ropivacaine for cesarean section.Methods:90 cases of cesarean section were divided into the two groups with 45 cases in each group,they were all received combined spinal-epidural anesthesia,the group A received subarachnoid injection of 0.5% ropivacaine 2.1 mL,the group B used subarachnoid injection of 0.375% ropivacaine 2.8 mL.The anesthetic effect was observed in the two groups.Results:There was a statistically significant difference in heart rate and blood pressure between patients in group A before and after anesthesia(P< 0.05).The duration of motor block in the group A was longer than that in the group B,the difference was statistically significant(P< 0.05).The use of ephedrine in the group A was more than that in the group B,the difference was statistically significant(P<0.05). Conclusion:0.375% ropivacaine applied in lumbar anesthesia has a lighter block on the motor nerves of the lower extremities,with faster recovery and more stable hemodynamics.
