目的比较相同浓度的罗比卡因与布比卡因用于小儿硬膜外术后镇痛的镇痛效果和并发症。方法选择60例行腰硬联合麻醉的腹部手术患儿随机分成两组行硬膜外术后镇痛,A组用0.1%罗比卡因,B组用0.1%布比卡因,每组分别复合芬太尼2ug/ml,镇痛泵容量为100ml,泵速为2ml/h,维持镇痛时间48h。观察指标有运动神经阻滞评分、手术后各时段的SpO2、BP、HR,OPS法镇痛效果评分、并发症情况。结果A组和B组比较,下肢运动阻滞程度两者相比差异有统计学意义(P<0.05),手术后观察各时段的SpO2、BP、HR,两者相比无显著性差异,OPS法镇痛效果评分两者相比差异无显著性(P>0.05),并发症两者相似(P>0.05)。结论0.1%罗比卡因复合芬太尼2ug/ml具有同0.1%布比卡因复合芬太尼2ug/ml同样的镇痛效应,而且对运动神经影响轻微,有利于患儿早期下床活动,用于小儿术后镇痛值得推广。 Objective To compare the analgesic effects and complications of the same concentrations of ropivacaine and bupivacaine for pediatric postoperative epidural analgesia. Methods Sixty children with abdominal surgery underwent combined spinal and epidural anesthesia were randomly divided into two groups: epidural analgesia (0.1%), group B (0.1% bupivacaine), and group B Compound fentanyl 2ug / ml, analgesic pump capacity of 100ml, pump speed 2ml / h, to maintain analgesic time 48h. The indexes included motor nerve block score, SpO2, BP, HR and OPS analgesia scores and complications at different time points after operation. Results There was significant difference in the degree of lower extremity block between group A and group B (P <0.05). SpO2, BP and HR were observed after operation. There was no significant difference between the two groups. OPS The analgesic effect score of the two methods showed no significant difference (P> 0.05), and the complications were similar (P> 0.05). Conclusion 0.1% ropivacaine combined with fentanyl 2ug / ml has the same analgesic effect as bupivacaine 0.1% bupivacaine 2ug / ml, and it has little effect on motor nerves and is beneficial to early ambulation , For postoperative analgesia worth promoting.
