自由体位分娩的探讨

Free Posture in Delivery

目的探讨孕妇采取自由体位分娩对促进产程及自然分娩的效果。方法随机将 2 0 0例初产妇分为两组各10 0例。观察组在第一产程采取行走、蹲、坐、趴、卧、半坐卧等自由体位分娩 ;第二产程取床头抬高 30～ 6 0°的侧卧位或半坐卧位、屏力 ,接产时采取截石位。对照组采取常规截石位、屏力分娩。结果观察组产程时间缩短、先露下降快 ,两组比较 ,差异有显著性意义 (P <0 .0 5 ,P <0 .0 1) ;剖宫产率、新生儿低评分率下降 ,但差异无显著性意义 (P >0 .0 5 )。结论自由体位分娩使产程加快 ,满足孕产妇心理需求 ,有利于母婴健康。

Objective To study the effect of free posture on labor duration and natural delivery. Methods Two hundred puerperae were randomly divided into two groups: observation group (n=100) with free posture (walk, squat, sit, lie, and so on in the first stage of labor; lie in bed with the heads upward 30-60° on their side or on the back in the early second stage of labor); control group (n=100) with routine posture during all stages of labor. Results In the observation group, the duration of labor was shortened, descent of the presentation was speeded up as compared with that in the control group (P<0.05, P<0.01). However, there was no significant difference in the rate of both cesarean section and neonatal asphyxia between the two groups (P>0.05). Conclusion The free posture delivery can shorten the labor.
