笑气吸入分娩镇痛的临床观察

Clinical Observation on Analgesia Labor with Inhaling Nitrous Oxide

目的:观察笑气吸入用于分娩镇痛的临床效果。方法:选择足月待产孕妇100例,随机分成观察组及对照组。观察组50例分娩时采用笑气吸入镇痛,对照组50例分娩时不吸入任何气体。观察记录两组疼痛程度,第一产程及总产程时间,新生儿apgar评分,产后出血量及分娩方式。结果:观察组疼痛程度轻,第一产程及总产程时间短,剖宫产率低,与对照组有显著差异(P<0.05)。观察组新生儿apgar评分及产后出血量与对照组无显著差异(P>0.05)。结论:笑气吸入用于分娩镇痛安全、有效、操作简单,值得临床推广。

Objective：To observe the clinical effect of analgesia for labor with inhaling nitrous oxide. Methods：One hundred pregnant women selected randomly in our hospital were divided into analgesia labor group （50 cases） and non-analgesia labor group （50 cases）. The degree of labor pain , the first delivery process and total process, new born＇s Apgar scores, postpartum hemorrhage, and the delivery way of two groups were recorded. Results：Pain degree of ana group was significantly lighter. Again the first delivery course and total course of ana gesia gesia abor abor group were significantly shorter than those of control group （P〈0. 05）. The rate of uterine incision delivery of analgesia group was significantly lower than that of control group （P〈0.05）. Postpartum hemorrhage and new born＇s Apgar score did not show significant difference between two groups （P〈0.05）. Conclusion： Analgesia labor with inhaling nitrous oxide is a safe, effective, and simple method. It is worth for popularization and application.
