Abstract: OBJECTIVE: Perinatal asphyxia is an important determinant of infant neurological outcome. There are very few studies looking exclusively at postasphyxial encephalopathy in preterm neonates. METHODS: We studied the neurologic and sonographic abnormalities in 40 preterm babies with severe birth asphyxia during their hospital stay and till 3 months corrected age. RESULT: 87.5 % of the asphyxiated preterm babies had neonatal neurologic abnormality, compared to only 17% of the control babies (p<0.0001). Generalised hypotonia and reduced activity were the commonest abnormalities (observed in 85% of asphyxiated babies) while depressed sensorium (60%) and seizures (35%) were seen in more severe cases. White matter disease (WMD-including periventricular flare, cerebral edema and periventricular leucomalacia) was significantly more frequent in the study cases (34.5% in study cases vs 7.5% in controls, p<0.0001) as was grade 3/4 intraventricular hemorrhage(IVH) (25% in study cases vs 2.5% in controls, p<0.0001). There was 11 fold higher mortality among the asphyxiated babies (23 deaths in study cases vs 2 in controls, p<0.0001). CONCLUSION: The survivors had a significantly higher incidence of both mild and severe neurological abnormalities at corrected age of 3 months among the asphyxiated babies. There was a good correlation between the severity of the neonatal encephalopathy as well as the sonographic findings and the outcome.
