笑气吸入用于分娩镇痛的临床研究

Clinical study on labor analgesia with inhalation of laughing gas

目的: 研究笑气吸入性分娩镇痛的疗效和对母儿的影响。方法: 将 280例产妇随机分为研究组和对照组。对照组除不给笑气吸入外, 其它产科处理措施与研究组相同。比较两组的产痛程度、产程时间、分娩方式、新生儿Apgar评分和副反应等情况。结果: 研究组的镇痛效果明显好于对照组, 活跃期和总产程短于对照组, 且剖宫产率明显降低, 差异均有显著性(P<0. 05)。结论: 笑气吸入用于分娩镇痛安全有效, 易被产妇接受, 增加阴道分娩率, 对产程和母儿无不良影响, 是一种理想的分娩镇痛方法, 值得产科临床推广使用。

Objective:To study the efficiency of inhaling laughing gas for labor pain relief and its effects on mother and fetus.Methods:280 primiparas were randomly divided into the study group and the control group. The control group was given the same treatments as that in the observational group but inhaling laughing gas. The degree of labor pains, delivery process, delivery ways, Apgar scores ,side effects and others were compared between the two groups.Results:The efficiency of relieving labor pain in study group was much better than that of control group, the duration of active phase and total delivery process was much shorter, and the rate of cesarean section was much lower than that in the control one, the differences were significant(P<0.05).Conclusion:Inhalation of laughing gas is safe and effective for labor analgesia. It is acceptable. The measure of relieving labor pain may increase the vaginal birth rate and shows no side effects on mother and baby, which is worthy of popularizing in obstetrics.
