Pak J Surg Jan ;31(1):66-9.

Objective: Th e aim of this study was to determine the incidence of birth trauma and risk factors related to fetal injury. Birth trauma at delivery is a rare but signifi cant prenatal complication. Materials and Methods: Birth trauma was evaluated in singleton fetuses with no major anomalies and with vertex presentations over a 3-year period from 2010 to 2012. One hundred and forty-eight neonates, who experienced birth trauma, were prospectively identifi ed and compared with 280 normal neonates. Both groups were delivered vaginally. Maternal and infant characteristics were evaluated as possible risk factors for fetal injury. Results: Among the 148 infants with birth trauma, nine had multiple injuries. Th e most common injury was cephalohematoma (n = 77). Other injuries included clavicle fractures (n = 56), brachial plexus paralysis (n = 13), asphyxia (n=7), facial lacerations (n=4), brain hemorrhage (n=1), and skin hematoma (n=2). Multiple regression analysis identifi ed premature rupture of membranes, instrumental delivery, birth weight, gestational age, induction of labor, and academic degree of att endant physician at delivery as the most signifi cant risk factors for birth trauma. Conclusion: Th e incidence of birth trauma was 41.16 per 1, 000 vaginal deliveries. Induction of labor, premature rupture of membranes, academic degree of att endant physician at delivery, higher birth weight, and gestational age were associated with fetal injuries.
