目的 探讨单次硬膜外阻滞在小儿麻醉中的优越性。方法 对单次硬膜外有适应症的患儿先行基础麻醉 ,再进行单次硬膜外阻滞 ;并与氯胺酮麻醉患儿在切皮时的心率变化和术毕苏醒时间进行比较。结果 单次硬膜外组麻醉前与切皮时心率变化无差异性 (P >0 .0 5 ) ;氯胺酮组则存在显著性差异 (P <0 .0 1) ,两组间在切皮时的心率变化和术毕苏醒时间、出血量均有显著性差异 (P <0 .0 1)。结论 单次硬膜外阻滞麻醉不增加患儿心率 ,术毕苏醒时间明显短于氯胺酮组 ,在临床应用中有一定价值 ,是腹部及其以下部位手术较为理想的麻醉方法。但需掌握好适应症和熟练的穿刺技术
Objective To explore the superiority of single epidural block in pediatric anesthesia. Methods A single epidural indications of children with basic anesthesia, and then a single epidural block; and ketamine anesthesia in children when the skin changes in heart rate and recovery time compared. Results There was no significant difference in heart rate between single epidural anesthesia and incision (P> 0.05), but there was significant difference between ketamine group and control group (P <0.01) Heart rate changes and recovery time after operation, the amount of bleeding were significantly different (P <0.01). Conclusion A single epidural anesthesia does not increase the heart rate in children, the recovery time was significantly shorter than the ketamine group, which has some value in clinical application. It is an ideal method of anesthesia in the abdomen and below. But need to master the indications and skilled puncture techniques
