Abstract Objective To explore the cesarean section rate and the clinical features of trial of vaginal delivery in primiparas of advanced maternal age after 37 weeks. Methods A retrospective study was conducted of the primiparas of advanced maternal age after 37 weeks of pregnancy in Beijing Obstetrics and Gynecology Hospital between January and July 2018. Data on the age, gravidity, history of adverse pregnancy, pregnancy complications, gestational weeks, mode of delivery, fetal distress, neonatal asphyxia of these primiparas was collected for statistical analysis. Results Among the 746 cases of delivery, 303 cases (40.62%)chose cesarean section and 443 cases (59.38%)requested trial of vaginal delivery, 75 of whom (16.93%)were transferred to cesarean section, 368(83.07%)had successful vaginal delivery and 38 cases (10.32%)delivered by forceps. In the group aged 35 to 37 and the group above 38 years old, the rate of transferred cesarean section was 17.24% and 15.15%, respectively, (P=0.870) and the rate of forceps delivery was 7.43% and 15.15%, respectively (P=0.021). The rates of neonatal asphyxia in the groups of elective cesarean section, transferred cesarean section and normal vaginal delivery were 5.30%,40.00% and 21.47%, respectively(P=0.000). Conclusions The chances of transferred cesarean section are not increased in the group above 38 years old. The rate of fetal distress in the transferred cesarean section group increases, but the rate of neonatal asphyxia does not. After adequate assessment, most of the primiparas of advanced maternal age after 37 weeks of pregnancy can have successful vaginal delivery.
