To investigate how macrosomia affects foetal-maternal birth outcomes, we conducted a retrospective cohort study of singleton pregnant women who gave birth at gestational age ≥37+0 weeks. The patients were divided into three groups according to birth weight: “macrosomia” group, ≥4500 g, n=285; “upper-normal” group, 3500–4499 g, n=593; and “normal” group, 2500–3499 g, n=495. Foetal-maternal and delivery outcomes were compared among the three groups after adjustment for confounders. Caesarean section was more frequent in the macrosomia group than in upper-normal and normal groups. The duration of labour (p < 0.05) and postpartum care at the hospital (p < 0.001) were the highest in the macrosomia group. Increased birth weight was associated with higher risks of shoulder dystocia (p < 0.001), increased bleeding volume (p < 0.001), and perineal tear (p < 0.05). The Apgar score at 5 minutes (p < 0.05), arterial cord pH (p < 0.001), and partial pressure of O2 (p < 0.05) were lower, while the arterial cord partial pressure of CO2 was higher (p < 0.001), in the macrosomia group. Macrosomia has potentially serious impacts for neonate and mother as a result of a complicated and occasionally traumatic delivery.

Our results indicate that satisfaction with labor and birth among primiparous women was unchanged 3 months after labor.

Purpose of investigation:To compare the maternal and neonatal outcomes of preterm premature rupture of the membranes (PPROM) between two management strategies. Materials and Methods: This retrospective cohort study involved 153 pregnant women who presented with PPROM at a gestational age of 28+0 to 36+6 weeks to evaluate the effects of expectant management (EM; labor > 36 hours) and active management (AM; labor < 36 hours) on maternal and neonatal outcomes. The EM and AM groups were also compared independently of gestational age and after being divided into two subgroups: early PPROM (gestational age 28+0 to 33+6 weeks) and late PPROM (34+0 to 36+6 weeks). Results: There were no differences between the AM and EM groups in the rates of maternal infection or placental abruption, or in neonatal outcomes, including low Apgar scores, respiratory distress syndrome, or the need for continuous positive airway pressure (CPAP). In the early PPROM subgroup, arterial umbilical blood base excess levels were more negative in the AM group (p = 0.007). In the late PPROM subgroup, the change in systolic blood pressure between admission to the maternity care center and membrane rupture was greater in the AM group (p = 0.049). Conclusions: There were no clinically significant differences in the maternal and neonatal outcomes of PPROM between AM and EM.
