笑气吸入用于分娩镇痛的临床研究

Clinical study on analgesic labor with inhaling laughing gas

目的 研究笑气吸入用于分娩镇痛的疗效和对母儿的影响。方法 对 12 0例产妇在分娩过程中给予吸入 5 0 %笑气与 5 0 %氧气混合气体 ,以实施分娩镇痛 (研究组 ) ,另选择 12 0例产妇在分娩过程中仅吸入氧气作对照 (对照组 ) ,其他产科处理与研究组相同。观察比较两组的产痛程度、产程时间、分娩方式、新生儿Apgar评分、产时出血量和产后出血率、产后乳汁分泌及产后尿潴留发生率等结果。 结果 研究组的阵痛强度评分明显低于对照组 (P <0 .0 1) ,研究组的活跃期和总产程时间短于对照组 (P <0 .0 5 ) ,差异有显著意义。 结论 笑气吸入用于分娩镇痛能显著减轻产痛 ,缩短产程 。

Objecitive To study the effficiency of inhaling laughing gas for labor pain relief and its effects on mother and fetus.Methods A total of 120 cases of pregnant women were provided with laughing gas premixed with oxygen (50%:50%)(control group);Another 120 cases were provided only with oxygen (comparison group).The degree of labor pains,delivery process,delivery ways,Apger scores,quantity of intrapartum hemorrhage,rate of postpartum hemorrhage,secretion of the mother′s milk,retention of urine and others were compared between the two groups.Results The score of labor pains in the observational group was significantly lower than that in the control one (P<0.01).The duration of active phase and total delivery process in the observational group was significantly shorter than that in the control one (P<0.05).Conclusions Analgesic labor with inhaling lauging gas produces a short delivery process and shows no side efffects on both mother and fetus,The inhalation of nitrous oxide for analgesia is a safe,effective and easy method.
