侧卧位分娩方式对母婴围生期结局的影响

Influence of the delivery method in the lateral position on the perinatal outcome of the mother and infant

目的分析第二产程使用侧卧位分娩方式对母婴围生期结局的影响。方法选择2019年5月至2021年3月在北京市大兴区妇幼保健院进行阴道分娩的124例产妇作为研究对象,采取随机数字表法将其分为对照组和研究组,每组各62例。对照组采取仰卧膀胱截石位,研究组采取侧卧位。比较两组的产程、会阴侧切以及Ⅱ度会阴裂伤数量、新生儿脐动脉血pH值、产后出血量。结果两组第一产程、第二产程、第三产程比较,差异无统计学意义(P>0.05)。研究组会阴侧切及Ⅱ度会阴裂伤比例均低于对照组,差异有统计学意义(P<0.05)。研究组新生儿脐动脉血pH值高于对照组,差异有统计学意义(P<0.05)。研究组产后2及24 h出血量少于对照组,差异有统计学意义(P<0.05)。结论在第二产程使用侧卧位分娩方式,有利于保护产妇会阴部,降低出血量,改善新生儿脐血pH值。该方式的使用对于硬件要求不高,便于临床推广使用。

Objective To analyze the influence of the lateral position delivery method in the second stage of labor on the maternal and infant perinatal outcome.Methods From May 2019 to March 2021,124 pregnant women who underwent vaginal delivery in Beijing Daxing Maternal and Child Care Hospital were selected as the research subjects.The parturients were divided into the control group and the study group according to random number table method,62 cases in each group.T he control group us ed supine bladder lithotomy position,the study group used lateral position.The labor time,the number of lateral perineal resection and second-degree perineal laceration,the pH value of neonatal umbilical artery blood,and the amount of postpartum hemorrhage of the two groups were compared.Results The data of the first stage of labor,the second stage of labor,and the third stage of labor between the two groups showed no statistically significant differences(P>0.05).The proportions of perineal lateral incision and second-degree perineal laceration in the study group were lower than those in the control group,the differences were statistically significant(P<0.05).The pH value of neonatal umbilical artery blood in the study group was higher than that in the control group,the difference was statistically significant(P<0.05).The bleeding volume of the study group at 2 and 24 h after delivery was lower than that of the control group,the differences were statistically significant(P<0.05).Conclusion In the second stage of labor,the delivery method using the lateral position is beneficial to protect the perineum of the woman,reduce the amount of bleeding,and improve the pH value of the cord blood of the newborns.The use of this method does not require high hardware requirements,so it is easy to promote and use.
