摘　　要：目的研究笑气吸入性分娩镇痛的效果和对母儿的影响。方法随机抽取250例无合并症及并发症、单胎头位、足月初产妇分为两组。观察组125例,自产程进入活跃期开始吸入笑气进行镇痛分娩;对照组125例,除不予笑气吸入外,其他产科处理措施与观察组相同。观察笑气吸入后镇痛效果和两组产程时间、分娩方式、羊水污染、产后出血量、新生儿Apgar评分及副反应。结果观察组产妇分娩镇痛强度总评分明显低于对照组(t=19.01,P<0.05),观察组活跃期和总产程时间短于对照组,差异有显著性(t值分别为2.35、2.13,均P<0.05),两组羊水污染、产后出血量、新生儿窒息率比较,均无显著性差异。结论笑气吸入性分娩镇痛产程时间短,对母儿均无不良影响,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 analgesic effect of inhaling laughing gas for labor pain and its influence on mother and the fetus. Methods 250 primiparae with term monocephesis and head presentation without any associations and complications were randomly divided into observation group and control group （in each group, n = 125 ）. The primiparae in the observation group were given laughing gas inhalation from active phase for labor analgesia while those primiparae in the control group were given same obstetric treatments as that in the observational group without giving laughing gas inhalation. The analgesic effect for labor pain in the observation group was observed, and duration of each stage of labor, delivery patterns, incidence of amniotic fluid contamination, Apgar score of the neonate, amount and incidence rate of postpartum hemorrhage and so on in the two groups were compared. Results The score of labor pains in the observational group was significantly lower than that in the control group（ t = 19.01, P 〈 0.05 ）. The durations of active phase and total delivery process in the observational group were significantly shorter than those in the control group （ t = 2.13, 2.35, respectively ; both P 〈 0.05 ）. While in incidence rate of amniotic fluid contamination, amount of postpartum hemorrhage and incidence of neonatal asphyxia, there were no significant differences between the two groups. Conclusion Analgesia in labor by inhaling laughing gas can shorten delivery process and had no side effects on both mother and fetus, so, it is an optimal analgesia in labor and is worthy to be popularized in obstetric clinic practice.
