目的:比较不同浓度布比卡因腰硬联合麻醉行剖宫产术的临床效果。方法:58例采用腰硬联合麻醉行剖宫产术产妇随机分3组。A组(n=18):腰麻用药为0.375%布比卡因等比重液2 ml;B组(n=20):腰麻用药为0.25%布比卡因等比重液2 ml;C组(n=20):腰麻用药为0.188%布比卡因等比重液2 ml。比较3组麻醉起效时间、麻醉效果及血压情况。结果:A、B组麻醉起效时间及麻醉效果相似(P>0.05),C组较A、B组起效时间延长、麻醉效果差(P<0.05);B组术中血压较A组平稳(P<0.05)。结论:0.25%布比卡因等比重液2 ml腰硬联合麻醉行剖宫产术起效快,作用完全,血流动力学稳定。
Objective: To compare the clinical effect of cesarean section with different concentrations of bupivacaine combined with spinal anesthesia. Methods: Fifty-eight women undergoing cesarean section underwent combined spinal and epidural anesthesia were randomly divided into 3 groups. Group A (n = 18): spinal anesthesia was 0.375% bupivacaine and other 2 ml; Group B (n = 20): spinal anesthesia 0.25% bupivacaine and other 2 ml; (n = 20): spinal anesthesia was 0.188% bupivacaine and other liquid 2 ml. The onset time of anesthesia, anesthesia and blood pressure were compared between the three groups. Results: The onset time and anesthesia effects of group A and group B were similar (P> 0.05). The onset time of group A and group B was longer than that of group A and B, and the anesthetic effect was poor (P <0.05). The intraoperative blood pressure of group B was more stable than group A (P <0.05). CONCLUSION: Cesarean section with 0.25% bupivacaine and other 2% specific gravity liquid combined with spinal and epidural anesthesia has rapid onset, complete effect and stable hemodynamics.
