Predicting conception and safe delivery of a macrosomic baby

Clinical data obtained prospectively from 98 neonates, 49 normal weight controls, and retrospectively from their mothers had revealed a low incidence of neonatal macrosomia and some important predictive indices of conception and safe delivery of such babies. All the macrosomic infants were singletons and above 37 weeks gestation. The incidence of macrosomia was 26 per 1,000 live births. Increasing maternal age (up to 28 years) parity (up to three) and height were positively correlated with the conception and safe delivery of a macrosomic baby. A maternal height of less than 1.64m was found to be associated with a higher risk of unsafe spontaneous vaginal delivery of a large infant. It is suggested that even in the developing countries all efforts should be made to confirm a diagnosis of foetal macrosomia before the onset of labour so that the mother can be properly assessed for the most appropriate method of delivery.
