本文对８５例先天性巨结肠根治术的硬膜外麻醉进行分析．由于小儿椎管（硬膜外腔）的解剖上特点，低浓度麻醉剂即可取得较满意的神经阻滞效果．本文探讨了小儿硬膜外麻醉的特点，对使用基础麻醉、麻药的浓度和容量，术中应注意小儿呼吸道的管理，常规吸氧，必须具备抢救条件及技术．提出在先天性巨结肠根治术中采用硬膜外（包括骶管）阻滞是一种安全可靠的麻醉方法． In this paper, 85 cases of Hirschsprung’s radical surgery of epidural anesthesia were analyzed. Due to the anatomical features of the pediatric spinal canal (epidural space), low-level anesthetics can achieve satisfactory neurological blockade. This article discusses the characteristics of pediatric epidural anesthesia, the use of basic anesthesia, anesthetic concentration and volume, surgery should pay attention to the management of children’s respiratory tract, routine oxygen, must have the rescue conditions and techniques. It is proposed that epidural (including caudal) blockade in radical hirschsprung’s disease is a safe and reliable method of anesthesia.
