目的观察不同浓度不同容量左旋布比卡因应用于小儿骶麻的镇痛效果及不良反应产生情况。方法 120例小儿下肢手术患者随机分为六组,每组20例。A、B两组为0.25%左旋布比卡因组,C、D两组为0.2%左旋布比卡因组,E、F两组为0.15%左旋布比卡因组。观察六组麻醉后情况并进行统计学分析。结果 E、F组患儿术中氯胺酮用量、恶心或呕吐的发生率明显大于其他四组,而疼痛五级评分法(LSP)<3级比率、平均镇痛时间、肌力恢复时间及肛门排气时间明显小于其他四组(P<0.05),D组平均镇痛时间、肌力恢复时间、肛门排气时间以及尿潴留的发生率明显小于A组(P<0.05)。结论小儿下肢手术应用骶管麻醉,0.2%左旋布比卡因0.7 ml/kg即可提供足够的麻醉平面,且并发症少,麻醉安全性高。
Objective To observe the analgesic effects and adverse reactions of levobupivacaine with different concentrations and different volumes applied in children with sacral anesthesia. Methods 120 cases of pediatric lower limb surgery patients were randomly divided into six groups, 20 cases in each group. Groups A and B were 0.25% levobupivacaine, groups C and D were 0.2% levobupivacaine, and groups E and F were 0.15% levobupivacaine. Six groups were observed after anesthesia and statistical analysis. Results The incidence of ketamine, nausea or vomiting was significantly higher in children in groups E and F than those in the other four groups. However, the pain relief score (LSP) <3 grade, mean analgesia time, muscle strength recovery time and anus row Gas time was significantly less than the other four groups (P <0.05). The mean analgesic time, muscle strength recovery time, anal exhaust time and urinary retention in group D were significantly less than those in group A (P <0.05). Conclusion caudal pediatric operation of caudal anesthesia, 0.2% levobupivacaine 0.7 ml / kg can provide adequate anesthesia plane, and fewer complications, high anesthesia safety.
