笑气用于分娩镇痛的安全性的研究

Clinical study on safety of labor analgesia with in halation of laughing gas

[目的]探讨笑气用于分娩镇痛的安全性。[方法]将300例产妇随机分为观察组和对照组、对照组除不给予笑气外,其他的产科处理措施与观察组相同。观察两组的分娩镇痛效果、产程时间、分娩方式,新生儿Apgar评分,产后出血量,母体动脉血气分析,吸入笑气的副反应等。[结果]观察组的阵痛强度评分明显低于对照组(P<0.001),总产程和活跃期均短于对照组,(P<0.05)差异有显著意义,而母体动脉血气分析,新生儿Apgar评分,产后出血量,分娩方式,吸入笑气副反应,均无统计学差异。[结论]笑气用于分娩镇痛是安全的。

[Objective]To approach the safety of inhaling langhing gas in labor analgesia.[Methods]300 primi- paras were randomly divided into the study group(n=150) and the control group(n=150).The same treat- ments were given to the two groups, except inhaling laughing gas which was only used in the study group. Two groups were compared with following indices:the degree of labor pain, delivery process, delivery ways, Apgar scores, postpartum bleeding volume, the analysis of blood gas, side effect of inhaling laughing gas.[Results]The score of labor pains in the study group was obviasly lower than that in the control one (P<0.001)The duration of active phase and whole delivery process in the study group was evidently shorter than those in the control group (P<0.05).There were no significantly differences in blood gas analysis, Apgar score, postpartum bleed- ing volume, dilivery ways, And side effect of inhaling langhing gas between two groups(P>0.05).[Conclu- sion]It is safe to apply inhaling laughing gas to the labor analgesia.
