Measuring the time it takes to achieve full oral feeding can be used as a low-resource tool to assess neurologic recovery after perinatal asphyxia.

The aims of this prospective study were to describe feeding difficulties in term infants with perinatal asphyxia and to determine whether the time it takes to achieve full oral feeding correlates with early neurological outcome in a high-income setting. Recruitment included 52 term infants with perinatal asphyxia: 32 without hypoxic-ischaemic encephalopathy (HIE), 9 with mild HIE, and 11 with moderate HIE. The time in days it takes to achieve full oral independent feeding was used as a marker of feeding difficulty. Early neurological outcome was evaluated using neonatal brain magnetic resonance imaging (MRI) and Hammersmith Infant Neurological Examination (HINE) at 3 months. In this cohort, 85% of infants (44/52) needed short-term assisted feeding after birth. The time it takes to achieve full oral feeding correlated with neonatal brain MRI findings and structured neurological examination results at three months. The time it takes to achieve full oral feeding could be a useful clinical measure to assess neurologic recovery after perinatal asphyxia, especially in low-resource settings.
