自由体位对产程及胎方位的影响

The influence of free posture on the birth process and fetal orientation

目的研究分娩过程中采用自由体位对产妇产程及胎儿胎方位的影响。方法选取2016年10月~2017年10月我院收治待产产妇86例作为研究对象,按随机数字表法分为两组,各43例。对照组孕妇采用传统体位待产,观察组产妇采用自由体位待产。观察两组产妇的胎方位、分娩方式、产程情况以及分娩结局。结果观察组孕妇的枕前位、自然分娩比例均高于对照组,枕横位、中转剖宫产比例均低于对照组(P<0.05)。观察组孕妇潜伏期、活跃期、第二产程时间均明显短于对照组(P<0.05)。两组患者产后出血、新生儿窒息发生率差异无统计学意义(P>0.05);观察组孕妇宫颈水肿和使用催产素的比例明显低于对照组,差异均有统计学意义(P<0.05)。结论自由体位分娩明显缩短产程,减少催产素的使用,改善妊娠结局,值得临床应用及推广。

Objective To study the clinical effect of free posture in the labor stage and fetal position.Methods Eighty-six puerpera delivered from October 2016 to October 2017 in our hospital were selected.The subjects were randomly divided into two groups,43 cases in each group.The control group was adopted the conventional delivery posture;the observation group was adopted the free delivery posture.The fetal position,delivery modes,labor stage and delivery outcomes were observed.Results The rate of occipitoanterior position and natural labor for observation group was significantly higher than that the control group;the rate of occipitotransverse position and transformation from natural labor to cesarean section for observation group was significantly lower than that in the control group(P<0.05);the incubation period,active phase and second labor stage courses for observation group were significantly shorter than that in control group(P<0.05);the rate of postpartum hemorrhage and neonatal asphyxia for two groups was not significantly different(P>0.05);the incidence rate of cervical edema and dosage of oxytocin for observation group were significantly lower than that in the control group,the differences were statistically significant(P<0.05).Conclusion The scientific free posture can greatly shorten the labor stage,reduce the dosage of oxytocin and improve the pregnancy outcomes.
