Abstract

|
Objective: We aimed to compare the maternal and neonatal morbidities associated with elective cesarean delivery (CD) without labor and those associated with induction of labor (IOL) at ≥38 weeks of gestation.
Methods: This retrospective observational study from 2013 to 2020 included singleton pregnancies in nulliparous women at ≥38 weeks of gestation. Maternal and neonatal morbidities associated with elective CD without labor were compared with those associated with IOL.
Results: Altogether, 395 women were recruited. Among these, 326 underwent delivery through IOL, while 69 underwent elective CD. The elective CD group exhibited higher maternal age, lower gestational age at birth, and lower neonatal birth weight than the IOL group (P<0.001). Moreover, the elective CD group exhibited longer hospital stay, higher rate of uterotonic agent usage, and lower rate of antibiotic usage after discharge. However, no differences were observed in postpartum bleeding, readmission, or number of outpatient visits (>3) after discharge between the groups. Perinatal morbidities were similar between the groups except the incidence of meconium-stained amniotic fluid. Elective CD exhibited similar rates of complications related to composite maternal morbidity when compared with IOL, but had a lower risk of complications related to composite neonatal morbidity (relative risk, 0.45; 95% confidence interval, 0.24-0.85).
Conclusion: Elective CD and IOL had similar rates of composite maternal morbidity but the former exhibited some benefits against obstetric wound infection. The elective CD group exhibited a decreased risk of composite neonatal morbidity despite lower gestational age at birth and higher maternal age.
