低频神经和肌肉刺激仪在产妇镇痛分娩中的应用及护理

Application of non-invasive low frequency nerve and muscle stimulator in labor analgesia

目的探讨低频神经和肌肉刺激仪(导乐仪)对产妇分娩镇痛效果及对母婴结局的影响。方法随机将在本院分娩的400例初产妇分为对照组与观察组,每组各200例,对照组采用全产程一对一导乐陪伴分娩,观察组在对照组基础上采用导乐仪镇痛分娩。比较两组产妇产时镇痛效果、产程进展、分娩方式、产后出血量及新生儿情况。结果观察组产妇产时镇痛效果、活跃期、第2产程和总产程时间及自然分娩率均优于对照组,两组比较,差异具有统计学意义(均P<0.05);两组新生儿窒息率及产后2h出血量比较,差异无统计学意义(均P>0.05)。结论产妇在全产程一对一导乐陪伴基础上采用导乐仪镇痛分娩,能有效减轻产妇产痛程度,加速产程进展,促进自然分娩,且对产妇及胎儿无不良影响,值得临床推广应用。

Objective To study the effect of non-invasive low frequency nerve and muscle stimulator on labor analgesia. Methods Four hundred primigravida in our hospital were randomized into the control and observation group in equal number：The deliveries of the former group were accompanied with full-process Doula and those of the latter with Doula-assisted analgesia besides Doula accompany.The two groups were compared in terms of analgesic effect,labor progress,delivery method,post-partum hemorrhage and neonatal conditions.Results The observation group was significantly better than the control group in terms of analgesic effect,active phase,total labor and spontaneous delivery（all P0.05）.There was no significant difference between them in occurrence of neonatal asphyxia and hemorrhage 2h after labor（both P0.05）.Conclusion Doula-assisted analgesia plus Doula accompany for the full labor process is effective for alleviating labor pains,accelerating labor process and spontaneous delivery.
