摘　　要：目的探讨笑气吸入分娩镇痛的疗效和对母儿的影响。方法将200例足月妊娠妇女随机分为观察组和对照组。对照组除不吸笑气外,其它观察指标同观察组。观察比较两组的产程时间及产痛程度、分娩方式、新生儿Apgar评分、产时出血量和产后出血率等。结果观察组镇痛评分明显低于对照组(P<0.01),观察组的活跃期[(2.44±1.38)h]和总产程[(7.21±2.66)h]均短于对照组[(2.86±1.48)h和(7.88±3.10)h](P<0.05)。结论笑气吸入性镇痛产程时间短,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 the efficiency of inhaling nitrogen monoxide in labor on pain relief and its effect on mother and fetus. Methods Two hundred term primiparas were randomly divided into the observational and control group. The control group was given the same treatments as that in the observational group except for inhaling of nitrogen monoxide. The degree of labor pains, duration of labor, mode of delivery, Apgar scores, the volume of intrapartum bleeding, the rate of postpartum hemorrhage and other outcomes were compared between the two groups. Results The scores of labor pains in the observational group was significantly lower（P〈0.01） and the duration of active phase and of the whole labor was significantly shorter than those of the control [（2.44±1.38） h vs （2.86± 1.48） h, （7.21±2.66） h vs （7.88±3.10） h, （P〈0.05）]. Conclusions Analgesic labor with nitrogen monoxide shortens the time of labor without adverse maternal and fetal outcomes and is effective.
