Neurodevelopmental outcome of 'at risk' nursery graduates.
A cohort study at a tertiary care neonatal service was undertaken to determine the neurodevelopmental outcome of neonates who required intensive care. One hundred and nineteen nursery graduates were enrolled for follow up if they fulfilled any of the following risk factors: birth weight less than 1500 g, Apgar score less than 4 at 5 minutes, seizure(s), and required assisted ventilation for more than 24 hours. They were subjected to periodic clinical evaluation and administered the Bayley Scales of Infant Development in early childhood. Of the total infants enrolled, 101 completed the required follow up. They included 55 infants with birth weight < 1500 g, 45 with low Apgar scores, 12 with seizure(s) and 28 who received assisted ventilation. An overwhelming majority of subjects (85%) had normal neurodevelopmental outcome. The adverse outcome in the remaining 15 included mental retardation in all, subnormal motor development in 14, microcephaly in 1, hearing loss in 2 and visual impairment in 4. Among the neonatal risk factors, seizures, sepsis and hypoxic ischemic encephalopathy had a significant association with adverse outcome. Despite serious neonatal morbidity, the early neurodevelopmental outcome of nursery graduates was reasonably good. The association of neonatal sepsis with neurodevelopmental sequelae merits a prospective evaluation.
