氧化亚氮吸入性分娩镇痛的临床观察

目的 :探讨氧化亚氮 (笑气 )吸入性分娩镇痛的有效性和安全性。方法 :选择单胎、头位足月、经阴道分娩、自愿接受氧化亚氮吸入进行分娩镇痛的初产妇 16 0例为观察组 ,条件等同无镇痛要求的产妇 10 0例为对照组 ,比较两组的产痛程度、产程时间、分娩方式、新生儿Apgar评分及产后出血等。结果 :在产痛程度、活跃期宫颈扩张速率方面 ,两组间差异具有非常显著性 (P <0 .0 1) ;第一、第二、第三产程、总产程、分娩方式、产后出血、新生儿Apgar评分方面 ,两组间差异无显著性 (P >0 .0 5 )。结论 :氧化亚氮吸入用于分娩镇痛效果肯定 ,对母儿无不良影响 ,是一种安全、有效、简便的无痛分娩方法 ,值得产科临床推广应用
