两种屏气用力方法在初产妇第二产程中的应用

Effects of two breathholding and exerting methods on the second labor course of primiparas

目的探讨两种屏气用力方法在初产妇第二产程中的应用效果。方法按产妇入院时间次序,将600例初产妇分为观察组和对照组,每组各300例。在第二产程中对照组产妇采用传统屏气用力方法,观察组采用呼吸技巧进行屏气用力。观察两组产妇分娩结局、会阴侧切率、屏气用力时间、产后2h出血量和新生儿窒息发生情况。结果观察组产妇自然分娩率较对照组高;会阴侧切率,产后2h出血量少于对照组;产妇屏气用力时间短于对照组,两组比较,差异均有统计学意义(P<0.05)。两组新生儿窒息发生情况比较,差异无统计学意义(P>0.05)。结论第二产程采用呼吸技巧进行屏气用力,可减少产妇体力消耗,提高产妇分娩效果。

Objective To explore the effects of two breathholding and exerting methods on the second labor course of primiparas.Methods Six hundred primiparas were divided according to the admission time into two groups： the control group and observation group. The former took conventional breathholding and exerting method and the latter breathholding and exerting method with breathing techniques. The two groups were compared in terms of outcome of delivery, rate of episiotomy, time for breathholding and exerting and the hemorrhage volume 2h after delivery, perineal laceration and neonate asphyxia.Results The rate of spontaneous delivery in the observation group was higher than that in the control group. The rate of episiotomy, bleeding volume 2h after delivery and perineal laceration were lower. The breathholding time was significantly shorter（ P〈0.05）.Conclusion Breathholding and exerting at the second stage of labor can reduce energetic consumption and improve the outcome of delivery.
