| ［摘要］ 目的 探讨布比卡因腰麻用于二次剖宫产手术的合适浓度。方法 选择60例择期行二次剖宫产术的产妇行腰-硬联合穿刺，随机分为A、B两组，每组30例，穿刺成功后分别向蛛网膜下腔注入0.5%(A组)和0.25%(B组)布比卡因7.5 mg，硬膜外腔置管备用。比较两组麻醉效果及不良反应发生情况。结果 两组产妇麻醉显效时间、腰麻平面、手术时间及新生儿Apgar评分差异无统计学意义(P均>0.05)；A组利多卡因使用率明显少于B组(P<0.05)，麻醉效果明显优于B组(P<0.05)。结论 腰-硬联合麻醉用于二次剖宫产时，腰麻应用0.5%布比卡因比0.25%的麻醉效果更为理想、安全。 |

| ［Abstract］ Objective To investigate optimal concentration of bupivacaine for lumbar anesthesia in undergoing second cesarean section.Methods Sixty patients who underwent the second caesarean section with spinal-epidural anesthesia were randomly divided into two groups. Every group involved 30 cases. Group A received 7.5 mg of 0.5% bupivacaine for lumbar anesthesia; group B received 7.5 mg of 0.25% bupivacaine. The anaesthetic effects and side effects were compared between the two groups.Results The effective time, anesthesia level, the operation time and newborn Apgar score had no distinct difference between two groups. The usage rate of lidocaine in group A were less than those in group B(P<0.05). The anaesthetic effects in group A was better than that in group B(P<0.05).Conclusion 0.5% bupivacaine is more effective and safe than 0.25% bupivacaine for lumbar anesthesia in second cesarean section. |
