目的：探讨不同速度注射轻比重罗哌卡对剖宫产术麻醉平面的影响。方法选择行剖宫产手术的孕妇60例,将其随机分成两组院Ⅰ组30例(注药速度30 s)和Ⅱ组30例(注药速度45 s),观察两组的阻滞平面、不良反应及需要追加局部麻醉药的情况。结果两组孕妇给药后5、10、15 min的胸阻滞平面情况比较,差异有统计学意义(P<0.05或P<0.01)；Ⅱ组的低血压发生率低于Ⅰ组(P<0.05),两组心动过速及恶心呕吐、寒战的发生率比较,差异无统计学意义(P>0.05)；两组均不需追加局部麻醉药。结论轻比重罗哌卡因腰-硬联合麻醉用于剖宫产手术,45 s给药速度所达到的平面更易于掌控,循环更稳定,更安全。

Objective To explore the impact of hypobaric ropivacaine with different injection rate on the anesthesia lev-el in cesarean section. Methods 60 pregnant women with cesarean sections were selected and randomly assigned into the two groups,there were 30 cases in each group:the group Ⅰ (injection rate:30 s) and the group II (injection rate:45 s).The block level,adverse effect and the requiring additional local anesthetics were observed. Results There was a sta-tistical difference of anesthesia getting to the block level after administration of 5,10,15 minites in the two groups (P<0.05 or P<0.01);the incidence rate of hypotension in theII group was lower than that in theⅠ group (P<0.05),the in-cidence rate of heartbeat tachycardia,nausea and vomiting,chills were compared in the two groups and there was no sta-tistical difference (P>0.05).Neither group needed additional local anesthetics. Conclusion When applying hypobaric ropivacaine for combined spinal-epidural anesthesia in cesarean section,injection rate of 45 s can facilitate control of the anesthesia level with more stable circulation and better safety.
