摘要
The appropriate timing of delivery for pregnancies has always been a concern for medical staff, and the timing of elective labor induction at 41 weeks in low-risk pregnant women has always been controversial. We compared maternal and fetal outcomes between gestational age at 40 0/7 to 40 6/7 and 41 0/7 to 41 6/7 weeks. This retrospective cohort study was conducted at the obstetrics department of Jiangsu Province Hospital from January 1(st) to December 31(st) in 2020. Maternal medical records and neonatal delivery data were collected. One-way analysis of variance, Mann-Whitney U test, ?(2) test, Fisher exact test and logistig regression analysis were performed. The study included 1569 pregnancies, with 1107 (70.6%) delivered at 40 0/7 to 40 6/7 weeks and 462 (29.4%) delivered at 41 0/7 to 41 6/7 weeks. Intrapartum cesarean section (8% vs 16%, P < .001), meconium-stained amniotic fluid (13% vs 19%, P = .004), episiotomy (41% vs 49%, P = .011), and macrosomia (13% vs 18%, P = .026) were significantly lower at 40 0/7 to 40 6/7 weeks. The premature rupture of membranes rate (22% vs 12%, P < .001), vaginal delivery rate of artificial rupture of membrane induction (83% vs 71%, P = .006) and balloon catheter combined with oxytocin induction (88% vs 79%, P = .049) were significantly higher at 40 0/7 to 40 6/7 weeks. Low-risk women who delivered at 40 0/7 to 40 6/7 weeks showed better outcomes in terms of the mother's and baby's health, such as decreased rates of intrapartum cesarean section, meconium-stained amniotic fluid, episiotomy, and macrosomia, compared with those who delivered at 41 0/7 to 41 6/7 weeks.
