目的 探讨氧化亚氮自控吸入镇痛 (BreathingNitrogenMonoxidePersonallyControllingAntalgic ,BNMPCA)对产程、分娩方式、围产儿预后等的影响。方法 随机选择住院分娩的产妇设立观察组和对照组 ,均无产科并发症。观察产痛程度、产程进展、分娩方式及围产儿预后。结果 ①产痛程度 :观察组吸入氧化亚氮前后及二组之间 ,视觉模拟评分 (VisualAnologueScale,VAS)比较差异有高度显著性 (P <0 .0 1 ) ;②产程进展 :二组潜伏期、加速期、第二产程差异无显著性 (P >0 .0 5) ,最大倾斜阶段、减速期差异有高度显著性(P <0 .0 1 ) ;③其他 :分娩方式、围产儿预后等差异无显著性 (P >0 .0 5)。结论 氧化亚氮自控吸入镇痛效果好 ,并可加快产程进展 ,对母婴无明显不良影响 ,值得临床推广使用。
Objective To investigate the effects of Breathing Nitrogen Monoxide (PVP) on Contra-injection Antalgic (BNMPCA) on labor course, mode of delivery and prognosis of perinatal children. Methods Maternal women who were randomly selected for hospital delivery were enrolled in the observation group and the control group, and no obstetric complications were found. Observe the degree of labor pain, labor progress, mode of delivery and perinatal prognosis. Results (1) The degree of pain produced: Before and after the inhalation of nitrous oxide in the observation group and between the two groups, there was a significant difference in the Visual Analog Scale (VAS) between the two groups (P <0.01); ② The progression of labor: There was no significant difference in acceleration phase and the second stage of labor between the two groups (P> 0.05). The difference between the maximal tilting phase and the deceleration phase was highly significant (P <0.01) .③Other: the mode of delivery and the prognosis of perinatal No significant (P> 0.05). Conclusion Nitrous oxide self-controlled inhalation analgesic effect, and can accelerate the progress of labor, no significant adverse effects on mother and baby, it is worth promoting the use of the clinic.
