目的:比较不同剂量罗哌卡因等比重腰麻在剖宫产术中的麻醉效果并探讨适宜剂量。方法:将80例行剖宫产手术产妇随机分为R9、R11、R13及R15组,分别给予9、11、13、15 mg的等比重罗哌卡因进行腰麻,比较4组在剖宫产术中的麻醉镇痛效果、新生儿Apgar评分、脐带血气分析以及低血压等不良反应发生率。结果:高剂量15 mg相比其他剂量能明显提供良好术中麻醉镇痛效果,其差异有统计学意义(P<0.05)。高剂量15 mg罗哌卡因腰麻术中低血压发生率明显高于其他3组,差异有统计学意义(P<0.05)。4组产妇在恶心呕吐、瘙痒、呼吸抑制、新生儿出生后1 min和5 min Apgar评分以及胎儿脐带血气分析等差异无统计学意义(P>0.05)。结论:高剂量罗哌卡因腰麻可以提供更好的术中镇痛效果,但应注意预防低血压。
OBJECTIVE: To compare the anesthetic effect of different doses of spinal anesthesia with different doses of spinal anesthesia in cesarean section and to explore the appropriate dosage. Methods: Eighty women undergoing cesarean section were randomized into groups R9, R11, R13 and R15. Ropivacaine (9, 11, 13, and 15 mg) Anesthesia analgesia during operation, neonatal Apgar score, cord blood gas analysis and incidence of adverse reactions such as hypotension. Results: Compared with other dosages, the high dose of 15 mg could significantly improve the analgesic effect of anesthesia. The difference was statistically significant (P <0.05). The incidence of hypotension in high dose 15 mg ropivacaine spinal anesthesia was significantly higher than the other three groups (P <0.05). No significant difference was found in the Apgar scores at 1 and 5 minutes after birth and in umbilical cord blood gas analysis between the 4 groups of maternal nausea, vomiting, itching, respiratory depression, neonatal birth (P> 0.05). Conclusion: High-dose ropivacaine can provide better analgesia during operation, but should be taken to prevent hypotension.
