蛛网膜下腔阻滞麻醉在小儿腹部与下肢手术中的应用研究

Clinical research of subarachnoid anesthesia in pediatric abdominal and lower limb surgery

目的 观察比较小儿腹部、下肢手术蛛网膜下腔阻滞与静脉麻醉的临床效果.方法 选择行腹部、下肢手术的小儿患者112例,随机分为两组,观察组56例选择蛛网膜下腔阻滞麻醉方法,对照组56例选择静脉复合全身麻醉.结果 两组患儿麻醉期间平均动脉压、心率、脉搏血氧饱和度、自主呼吸恢复时间、拔管时间比较,差异均有统计学意义（P均＜0.05）.观察组麻醉并发症发生率为12.50％,显著低于对照组的91.07％,差异有统计学意义（P＜0.05）.结论 小儿腹部、下肢手术蛛网膜下腔阻滞优于静脉复合全身麻醉,它可提供足够的麻醉平面,减少麻醉并发症,提高小儿麻醉安全性.

Objective To observe the clinical effective of subarachnoid block and intravenous anesthesia in pediatric abdomen and lower limb surgery.Methods One hundred and twelve children underwent the abdominal and lower extremity surgery were randomly divided into two groups.Fifty-six cases in the observation group were given subarachnoid block anesthesia,56 cases in the control group were given combined intravenous general anesthesia.Results The differences of MAP,HR and SpO2 of the children during anesthesia,the spontaneous breathing recovery time and extubation time between the two groups were statistically significant（P ＜0.05）.The anesthesia complication rate of the observation group was 12.50％,which was significantly lower than the control group （91.07％）,the difference was significant（P ＜ 0.05）.Conclusions The subarachnoid block is better than intravenous general anesthesia in pediatric abdominal and lower limb surgery,which can provide a sufficient level of anesthesia,reduce anesthetic complications and improve the safety of pediatric anesthesia.
