小剂量布比卡因等比重腰硬联合麻醉在剖宫产手术中的应用

The Clinical Application of Low Dose Bupivacaine For CSEA in Caesarean Section

目的探究小剂量布比卡因等比重腰硬联合麻醉(CSEA)在剖宫产手术中的应用效果。方法 A组以0.75%布比卡因1.2 mL等比重液行CSEA,B组0.75%布比卡因1.2 mL重比重液,观察对比两组的麻醉效果。结果 A组较B组在各时间段的血液动力学波动较平稳,且镇痛持续时间、运动阻滞持续时间长于B组,运动和感觉恢复时间均短于B组,另外,A组产妇术中低血压发生率明显低于B组,P<0.05。结论采用小剂量布比卡因等比重腰硬联合麻醉,血流动力学平稳,不良反应少,运动和感觉恢复快。

[ Objective ] To explore the effect of low dose bupivacaine for CSEA in caesarean section. [ Methods ] Patients of the A group were CSEA with 1.2 mL of 0.75% bupivacaine isobaric, and patients of the B group were CSEA with 1.2 mL of 0.75% bupivacaine, then observe and compare the two groups of anesthesia. [ Results ] The fluctuation of hemodynamics of the A group was relatively more stable than that of the B group in each period; the pain duration and the duration of motor block were longer than that of the B group, and the motor and sensory recovery time were shorter than that of the B group. In addition, hypotension cesarean patients in A group was significantly lower than those in the group B, P〈0.05. [ Conclusion ] The use of low dose bupivacaine for CSEA in caesarean section could keep hemodynamie stability and less adverse reaction, shorten the motor and sensory recovery stage.
