ObjectiveTo explore the effect of natural delivery and cesarean section on early uterine recovery in primiparas.Methods300 primiparas delivery in our hospital from April 2016 to July 2016 were selected and divided into natural delivery group and cesarean section group according to the delivery mode,with 150 cases in each group.Both groups received obstetric routine care in prenatal and postpartum.The natural delivery group were given natural childbirth,while the cesarean section group were given lower uterine cesarean section.The postpartum uterine descent speed, the postpartum lochia situation and the uterine recovery situation were compared between the two groups.ResultsThe postpartum uterine descent speed in the natural delivery group [(1.83±0.27)cm]was faster than that in the cesarean section group [(1.23±0.33)cm];the postpartum bloody lochia duration and the time of lochia of natural delivery group [(2.59±0.78),(30.28±2.74)d]was shorter than that in the cesarean section group[(3.83±1.02),(40.35±3.42)d];the uterine recovery rate of natural delivery group (96.0%)was higher than that in the cesarean section group (86.0%),the differences were statistically significant(P＜0.05).ConclusionNatural delivery compared to cesarean section is more conducive to postpartum uterine recovery.Health care workers should strictly control the indications for cesarean section and do a good job of health education and guidance to reduce cesarean section rate.
