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 efficacy of inhaling labor-induced analgesia and its impact on maternal and childbirth. Methods: 280 maternal women were randomly divided into study group and control group. In addition to the control group did not inhaled nitrous oxide, the other obstetric treatment and research group the same. The pain intensity, labor duration, mode of delivery, neonatal Apgar score and side effects were compared between the two groups. Results: The analgesic effect of the study group was significantly better than that of the control group, the active phase and the total production were shorter than the control group, and the cesarean section rate was significantly lower (P <0.05). Conclusion: The inhalation of nitrous oxide is safe and effective for labor analgesia. It is easy to be accepted by the mothers and increases the rate of vaginal delivery. It has no adverse effect on the labor process and maternal and childbirth. It is an ideal method for labor analgesia and is worth popularizing in obstetrics.
