自由体位分娩对阴道分娩生殖道损伤及产后出血的影响探讨

Effect of Free Posture Delivery on Reproductive Tract Injury and Postpartum Hemorrhage in Vaginal Delivery

目的探讨自由体位分娩对阴道分娩生殖道损伤及产后出血的影响。方法选择2015年6月至2016年6月来我院进行分娩的126例产妇作为此次研究对象,将其分成对照组与观察组,各63例。对照组产妇采用常规体位分娩,观察组患者采用自由体位分娩,比较两组产妇分娩时的生殖道损伤状况以及产后出血情况。结果观察组产妇的顺产率(56例,88.89%)明显高于对照组产妇(40例,63.49%)。两组产妇的会阴Ⅱ、Ⅲ度裂伤没有明显的差异(P>0.05)。但是观察组产妇的会阴Ⅰ度裂伤、宫颈裂伤以及会阴侧切发生率明显比对照组低。观察组产妇的第一产程、第二产程、第三产程以及总产程时间均比对照组产程时间短。观察组产妇产后出血量(253.12±5.21)ml明显低于对照组产后出血量(498.37±5.36)ml,两组间比较具有统计学意义(P<0.05)。结论自由体位分娩有利于加快产妇的分娩产程,提高患者自然分娩的概率,减少患者生殖道损伤以及产后出血量。值得在临床医学上应用并推广。

Objective To investigate the influence of free posture delivery on vaginal delivery, genital tract injury and postpartum hemorrhage. Methods From June 2015 to June 2016 in our hospital for delivery of 126 cases of maternal as the object of study, they were divided into the control group and the observation group, 63 cases each. The control group adopted routine position delivery, the observation group was given free position delivery, and the reproductive tract injury status and postpartum hemorrhage were compared between the two groups. Results the spontaneous labor rate of the observation group(56 cases, 88.89%) was significantly higher than that of the control group(40 cases, 63.49 %). There was no significant difference between the two groups in the degree of laceration of perineum II and III(P>0.05). But the incidence of perineal first degree laceration, cervical laceration and episiotomy were lower in the observation group than in the control group. The first stage of labor, postpartum hemorrhage in the observation group during the second stage of labor, the third stage of labor and total labor time were shorter than the control group labor time. The postpartum hemorrhage volume of the observation group(253.12±5.21ml) was significantly lower than that of the control group(498.37±5.36ml), and the difference between the two groups was statistically significant(P<0.05). Conclusion Free posture delivery is helpful to speed up the delivery process, improve the probability of natural childbirth, reduce the reproductive tract damage and postpartum hemorrhage. It is worthy to be applied and popularized in clinical medicine.
