Objective: To investigate the delivery modes of women with repeat pregnancies involving uterine scars and their effects on both mothers and neonates. Methods: A study was conducted on 100 patients treated at Shenzhen Maternity and Child Healthcare Hospital from July 2023 to July 2024. The participants were divided into a control group and an observation group, with 50 cases in each. The division was based on the indications for prior cesarean section, cervical maturity, postpartum complications, and thickness of the cesarean scar. The control group underwent cesarean delivery, while the observation group experienced vaginal delivery. The two groups were compared in terms of intrapartum blood loss, postpartum blood loss within 2 hours, length of hospital stay, Apgar scores at 1-minute post-birth, and incidences of neonatal fever and jaundice. Results: The observation group had significantly lower intrapartum blood loss, postpartum blood loss within 2 hours, and shorter hospital stays compared to the control group (P < 0.05). Additionally, the Apgar scores at 1 minute post-birth were significantly higher in the observation group (P < 0.05). The incidence of neonatal fever and jaundice was significantly lower in the observation group (P < 0.05). These differences were statistically significant. Conclusion: Vaginal delivery has high clinical value for women with repeat pregnancies involving uterine scars. It reduces maternal intrapartum and postpartum blood loss, shortens hospital stays, improves neonatal Apgar scores, and decreases the incidences of neonatal fever and jaundice. This method is worthy of clinical application and promotion.
