轻比重与重比重布比卡因腰-硬联合麻醉在剖宫产术中的比较

目的 比较轻比重布比卡因和重比重布比卡因腰-硬联合麻醉在剖宫产手术中的麻醉效果.方法 选择80例ASAⅠ或Ⅱ级剖官产手术患者,随机分为A、B两组,每组40例.其中A组用轻比重0.167％布比卡因(0.5％布比卡因2 mL+灭菌水4mL),B组用重比重0.5％布比卡因(0.75％布比卡因2mL+10％葡萄糖液1 mL).术中持续监测呼吸、循环状况及血流动力学变化,评估麻醉效能及不良状况.结果 A组术中各时点BP、HR、SpO2较为平稳；B组麻醉术中各时点BP明显下降,HR明显减慢(P＜0.05),也低于A组(P＜0.05),两组新生儿改良Bromage评分和不良反应无统计学意义.结论 轻比重布比卡因腰-硬联合麻醉更适合于剖宫产患者.

Comparison-of hypobaric bupivacaine and hyperbaric bupivacaine of combined spinal-epidural anesthesia in cesarean section

Objective To compare the anesthetic effect of hypobaric bupivacaine and hyperbaric bupivacaine of com- bined spinal-epidural anesthesia in cesarean section. Methods Eighty cases of cesarean section surgery patients（ASA I-Ⅱ level） were randomly divided into group A and group B, 40 cases in each group.Patients in group A used 0.167% hypobarie bupivacaine （0.5% bupivacaine 2 mL＋sterilizing water 4 mL）,while the patients in group B used 0.75% hyperbaric bupivacaine （0.75% hyperbaric bupivaeaine 2 mL＋10% glucose 1 mL）.Continuously monitored the respiration, circulation conditions,hemodynamic changes in the operation,and evaluated the anesthetic effect and adverse conditions. Results The BP, HR, SpO2 of group A were relatively stable,while the BP of group B was significantly decreased, HR was significantly slowed （P 〈 0.05） ,and lower than group A （P 〈 0.05）. The neonatal modified Bro- mage score and adverse reactions of the two groups were not significant different （P 〉 0.05）. Conclusion The hypo- baric bupivacaine of combined spinal-epidural anesthesia is more suitable for patients with cesarean section.
