目的研究氧化亚氮吸入性分娩镇痛的疗效和对母婴的影响。方法将200例产妇随机分为观察组和对照组。对照组除不给氧化亚氮吸入外,其他产科处理措施与观察组相同。观察比较二组的产痛程度、产程时间、分娩方式、新生儿Apgar评分、产时出血量等。结果观察组的镇痛强度评分明显低于对照组(P<0.01),观察组的活跃期和总产程时间明显短于对照组(P值均<0.05),差异有统计学意义。结论笑气吸入性分娩镇痛产程时间短,对母婴均无不良影响,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 effect of nitrous oxide inhalation on labor analgesia and its effect on mother and infant. Methods 200 maternal women were randomly divided into observation group and control group. In addition to the control group was not inhaled nitrous oxide, other obstetric treatment and observation group the same. Observe and compare the two groups of the degree of labor pain, labor process, mode of delivery, neonatal Apgar score, amount of bleeding during delivery. Results The analgesic intensity of the observation group was significantly lower than that of the control group (P <0.01). The active group and the total labor time of the observation group were significantly shorter than those of the control group (P <0.05). The difference was statistically significant. Conclusions Short-term labor-induced labor analgesia with short duration of labor has no adverse effects on maternal and childbirth. It is an ideal method for labor analgesia and is worth popularizing in obstetrics.
