摘要
目的探讨笑气在阴道分娩中的镇痛作用,以及对产程进展和新生儿出生结局的影响。方法236例初产妇,孕37～41周、单胎、头位,无头盆不称,无妊娠合并症为治疗组,另外选择同期210例初产妇作为对照。分析两组病例在产程中的疼痛反应程度和产程进展以及新生儿出生评分情况。结果观察组在分娩过程中对疼痛的反应程度明显低于对照组,总产程时间明显短于对照组,差异有显著意义,新生儿窒息率和对照组无明显区别。结论笑气用于活跃期镇痛是一种有效、安全,能够在社区医院中推广使用的镇痛服务。
Objective To explore the efficacy of inhalation of nitrous oxide at active phase during labor, as well as the effects on delivery progression and outcome of newborns. Methods 236 primigravida, with 37-41 weeks of pregnancy, single fetal, head position and normal pelvimetry, without pregnancy complicated diseases, were recruited as study group,simultaneously, 210 were selected as the control. Pain reaction, the progression of labor and outcome of newborns were recorded. Results Patients in study group had significantly low grade of pain reaction than the control （P〈0.05）, and the total time of labor was shorter in the study group （P〈0.05） while the prevalence of suffocation in newborn had no significant difference between two groups （P〉0.0.5）. Conclusion The inhalation of nitrous oxide, as effective and safe measure, could be used to alleviate labor pain at active phase, which may be deserved to extend at community-leveled hospitals.
