目的:观察笑气吸入镇痛的效果及对母婴的影响。方法:随机选择60例采用面罩吸入笑气作为观察组;60例未采用任何镇痛方法作为对照组,观察比较两组的疼痛程度、产程时间、分娩方式、产后2小时出血量、新生儿Apgar评分。结果:观察组的疼痛明显低于对照组(P<0.0001),总产程明显短于对照组(P<0.05),其差异有显著意义,其它方面两组比较差异无显著性。结论:笑气吸入能明显减轻疼痛,缩短产程,对母婴无不良影响,方法简单,是一种较为理想的分娩镇痛方法。
Objective: To observe the effect of inhaling nitrous oxide on pain relief and its effect on mother and infant. Methods: 60 cases were randomly selected to receive inhalation of nitrous oxide as the observation group; 60 cases without any analgesic method as the control group were observed and compared the degree of pain, labor duration, mode of delivery, 2 hours postpartum hemorrhage, neonatal Apgar score. Results: The pain in the observation group was significantly lower than that in the control group (P <0.0001). The total length of labor was significantly shorter in the observation group than in the control group (P <0.05). There was no significant difference between the two groups. Conclusion: Inhalation of nitrous oxide can significantly reduce the pain, shorten the labor process and have no adverse effect on maternal and infant. The method is simple and is an ideal method of labor analgesia.
