氧化亚氮吸入用于分娩镇痛对母儿的影响

目的　研究氧化亚氮 (笑气 )吸入分娩镇痛对母儿的影响。方法　随机选择 5 8例产妇作为观察组 ,6 0例产妇作为对照组。观察两组产妇的产程时间、分娩方式、产后 2h出血量、羊水粪染率、新生儿Apgar评分。结果　观察组第一产程活跃期较对照组缩短 (P <0 0 5 ) ,其他方面两组比较 ,差异无显著意义。结论　笑气吸入镇痛对母儿均无不良影响 ,方法简单 ,值得临床推广使用。

The effects of inhaling nitrous oxide for labor analgesia on mater and fetus

Objective To investigate the effect of the inhalation of nitrous oxide premixed with oxygen(50%∶50%)for labor analgesia on mater and fetus.Methods 58 cases of pregnant women were randomly chosen as observation group,another 60 cases as control group.The duration of the labor,way of delivery,bleeding volume,rate of meconium-stained amniotic fluid and Apgar score were compared between the two groups.Results The active phase of the first stage in the observation group was shorter than that in the control group(P<0.05),but there was no significant difference in other respects between the two groups.Conclusion Analgesia with inhaling nitrous oxide shows no side-effect on mater and fetus.It is a simple method and worthy of popularizing.
