Clinical observation of doila combined with GT-4a pulse therapy for labor analgesia

目的 观察脉冲波疗法加导乐用于分娩镇痛的效果以及对分娩方式、产程干预、母儿并发症的影响.方法 将自愿要求分娩镇痛的初产妇196例随机分为镇痛组和对照组,每组各98例.两组产妇在宫口开大2～3 cm时均由一名高年资的助产师导乐分娩,镇痛组的产妇使用GT-4A分娩镇痛工作站给予脉冲波疗法.结果 镇痛组使用脉冲波疗法分娩镇痛后0.5 h、1 h、2 h、3 hVAS评分与镇痛前和对照组相比明显下降（P＜0.05）,与对照组相比,镇痛组第一产程活跃期[（132.48±48.32）min]加速明显,第二产程[（40.13±18.28）min]缩短,且剖宫产率（13.27%）及新生儿轻度窒息发生率（3.61%）明显下降（P＜0.05）.而两组阴道助产率、第三产程及产后出血、新生儿重度窒息发生率两组差异无统计学意义（P＞0.05）.结论 脉冲波疗法加导乐镇痛效果良好,缩短产程,降低剖宫产率,提高产科质量,对母儿无不良影响.
