RESUMO
BACKGROUND: Fetal macrosomia is associated with an increased risk of adverse outcomes to both the mother and the infant. AIM: To determine maternal and neonatal outcomes associated to fetal macrosomia in diabetic and non- diabetic mothers. METHODS: It is a descriptive retrospective study conducted in Tunisia. We included in this study all patients who delivered newborns having a birth weight above 4kg during 2013. Multivariate analysis was performed using binary logistic regression to identify the complications associated to macrosomic pregnancies with diabetes. RESULTS: Among the 10186 deliveries registered during the study period, 821 mothers gave birth to macrosomic newborns. The prevalence of macrosomia was 8.1%, and macrosomic newborns who had a birth weight of 4500 g or greater were 1.06%. Macrosomia was significantly higher in males (p <10-3). The rate of cesarean delivery was 47.9%. The most frequent adverse maternal and neonatal outcomes were perineal tears (3.6%), post-partum hemorrhage (0.6%), shoulder dystocia (4.9%) and neonatal intensive care unit admission (7.6%).The proportion of maternal diabetes was 9.3%. Macrosomic pregnancies with diabetes appear to be significantly associated with cesarean delivery (OR=2.22), postpartum hemorrhage (OR=6.69) and neonatal intensive care unit admission (OR=4.18). CONCLUSION: Macrosomia increases the risk of maternal and perinatal morbidity particularly when it was associated to maternal diabetes.
