摘　　要：目的:探讨笑气吸入镇痛用于人工流产术的效果。方法:将采用笑气吸入镇痛的100例人工流产患者作为观察组,100例吸入安慰剂(即氧气)的患者作为对照组,观察两组患者人工流产时疼痛程度、宫颈松弛情况和不良反应。结果:观察组无痛(0级)与轻微疼痛(Ⅰ级)者的比例达95%,而对照组仅22%,差异有统计学意义(P<0.01);观察组的宫颈松弛程度总有效率为93%,而对照组为29%(P<0.01);人工流产综合征发生率观察组为2%,对照组为14%(P<0.01);两组的平均出血量比较,差异无统计学意义(P>0.05)。结论:笑气吸入镇痛简单易行,无不良反应,是妇产科门诊人工流产术一种比较理想的镇痛方法,值得临床推广。Objective To explore the effect of Nitrous Oxide in relieving pain in the induced abortion. Method For 100 cases used Nitrous Oxide in inhalant anaesthesia in induced abortion for relieving pain as the observation group, 100 cases inhaled placebo （oxygen） as the contrast group. Pain degree in induced abortion, the grade of cervix looseness and the adverse effect were observed in the two groups. Results The rate of painless and light pain in the observation group was 95% , while in the contrast group was 22% （ P 〈 0.01 ） ; the efficiency rate of the grade of cervix looseness in the observation group was 93%, while the contrase group was 29% （P 〈0.01 ） ; the occurrence rate of syndrome of induced abortion in the observation group was 2%, while the contrast group was 14% （ P 〈 0.01 ） ; and there was no obvious difference of bleeding amount in the two groups. Conclusion Nitrous Oxide absorption analgesia is easy, with no side effect and it is an ideal analgesia method in abortion in gynecology and obstetrics. The method is deserved clinical application.
