新生儿出生体重与分娩结局的关系

The relationship between birth weight and delivery outcome in newborns

目的探讨新生儿出生体重与分娩结局的关系。方法选择2015年1月～2016年7月在我院住院分娩单胎活产新生儿1416例为观察对象。比较新生儿低体重组、正常体重组、巨大儿组的分娩结局。结果随着新生儿出生体重的增加，阴道分娩率逐渐下降，剖宫产率逐渐升高；阴道分娩新生儿中巨大儿组新生儿窒息、肩难产、产后出血等的发生率明显高于低出生体重组＋正常组，差异有统计学意义（P〈0．05）。结论加强对孕产妇孕期管理、控制新生儿体重对降低剖宫产率、改善分娩结局对保障母婴健康具有重要意义。

Objective To explore the relationship between birth weight and de ery outcome in newborns. Methods 1416 cases of singleton infants who were born in our hospital from January 2015 to July 2016 were selected as observa- tion subjects. The delivery outcomes of low body weight group, normal weight group and fetal macrosomia group of newborns were compared. Results With the increase of birth weight, vaginal delivery rate was gradually decreased and the rate of cesarean section was increased. The incidence of neonatal asphyxia, shoulder dystocia, and postpartum hem- orrhage in the newborn of vaginal delivery was significantly higher than that of low birth weight group and normal group, and the difference was statistically significant（P〈0.05）. Conclusion Strengthening the management of pregnant women in pregnancy and controlling the birth weight of newborns are of great significance for reducing the rate of ce- sarean section, improving the outcome of childbirth and protecting maternal and child health.
