对３４ 例拟行腹部急诊手术的新生儿给以骶管阻滞并进行临床观察。采用单次或连续骶管阻滞的方法，对 ４ｈ～２８ｄ 的新生儿进行麻醉，观察围术期心率、血压、呼吸、体温、脉搏、血氧饱和度等生命体征变化。结果表明：所有观察对象麻醉效果满意，生命体征平稳。说明新生儿骶管阻滞操作简单，安全可靠，适用于腹部急诊手术的麻醉。 A total of 34 newborn infants undergoing emergency abdominal surgery were given sacral block and clinical observation. A single or continuous caudal block method was used to anesthetize neonates from 4 h to 28 d. Changes of vital signs such as heart rate, blood pressure, respiration, body temperature, pulse rate and oxygen saturation during perioperative period were observed. The results showed that: all the subjects were satisfied with the anesthetic effect and the vital signs were stable. Description of neonatal sacral block simple, safe and reliable, suitable for emergency abdominal surgery anesthesia.
