不同浓度低比重布比卡因腰麻剖宫产对产妇循环和新生儿的影响

目的 观察不同浓度低比重的布比卡因对产妇血流动力学及新生儿Apgar评分的影响.方法 择期行剖宫产产妇80例,随机均分成H组(0.3755%布比卡因7.5 mg)和L组(0.25%布比卡因7.5 mg).记录各组麻醉前、麻醉后5-、10-min、胎儿娩出即可的SpO2、HR、SBP、DBP及新生儿1-、5-min的Apgar评分.结果 麻醉后5-min,H组SBP、DBP与麻醉前比较明显降低(P<0.05),也明显低于L组(P<0.05);新生儿出生后1-、5-min的Apgar评分组间差异无统计学意义.结论 0.25%低比重布比卡因可有效降低剖宫产术中低血压的发生率.

Low proportion of different concentrations of bupivacaine cesarean section on maternal circulation and neonatal

Objective To observe the different concentrations of the low proportion of bupivacaine on maternal bemodynamics and neonatal Apgar score. Methods 80 cases of elective cesarean section were randomly divided into Group H （0. 375% bupivacaine 7. 5 mg） and L group （0. 25% bupivaeaine 7.5 mg）. Recorded be- fore each group of anesthesia, anesthesia5 -, 10 -min, the baby is delivered to the SpO2, HR, SBP, DBP and neonatal 1 -, 5 -min the Apgar score. Results Anesthesia 5-min, Group H of SBP, DBP compared with those be- fore anesthesia significantly reduced （P 〈 0. 05 ） was significantly lower than the L group （P 〈 0. 05 ） ; after birth, 1 -, 5 -min Apgar score group between The difference was not statistically significant. Conclusion 0. 25% Low bupivacaine can effectively reduce the incidence of hypotension during cesarean section.
