Objective To investigate the pregnancy outcomes of singleton low-risk pregnant women who had a trial delivery in different gestational weeks,thus providing scientific basis for timely termination of pregnancy in the third trimester.Methods A retrospective analysis was performed on 993 singleton low-risk pregnant women who had a trial delivery in the Fourth Hospital of Shijiazhuang City from April to July 2021,they were divided into the 39-39+6 weeks gestation group(n= 358)including 316 cases of natural labor and 42 cases of induced labor,the 40-40+6 weeks gestation weeks(n= 376)including 320 cases of natural labor and 56 cases of induced labor,and the 41-41+6 weeks gestation group(n = 259)including 103 cases of natural labor and 156 cases of induced labor.The clinical data were collected to analyze and the basic situation of pregnant women among the three groups.The rates of cesarean section on intermediate,vaginal midwifery,postpartum hemorrhage,macrosomia,contamination on amniotic fluid,neonatal asphyxia and neonatal transfer to pediatrics were compared among the three groups.Results There was no significant difference in the basic status of pregnant women among the three groups(P>0.05).The rate of vaginal midwifery,cesarean section on intermediate,contamination on amniotic fluid,and macrosomia of pregnant women with natural labor in the 39-39+6 weeks gestation group and the 40-40+6 weeks gestation group were significantly lower than those of the 41-41+6 weeks gestation group(P<0.05).The rate of cesarean section on intermediate,postpartum hemorrhage,and contamination on amniotic fluid of pregnant women with induced labor in the 39-39+6 weeks gestation group and 40-40+6 weeks gestation were significantly lower than those of the 41-41+6 weeks gestation group(P<0.05).Conclusion The optimal gestational week of singleton low-risk pregnant women is 39-39+6 weeks,and the latest should not exceed 41 weeks,which can effectively improve the outcome of labor,reduce the occurrence of obstetric complications,and improve the quality of obstetrics.Therefore,reasonable clinical intervention or timely termination of pregnancy may increase the natural delivery rate after 39 weeks of pregnancy.
