Abstract

Accurate identification and characterization of the severity, extent, and location of brain injury is essential to predict the neurodevelopmental outcome of newborns. The pattern of brain injury depends on the severity and duration of hypoxia and degree of brain maturation. Various neuroimaging modalities such as neurosonogram, CT, MRI are available which help in identification of severity of brain injury. Initial scans were obtained within 72 hrs of birth and subsequent follow up scans were done on 8-10th day and 30th day so as not to miss the relatively late developing intracranial changes. The infants were then followed up after 6-12 months for a detailed neurological assessment for correlation of clinical outcome with NSG findings using statistical analysis. In our study 66% newborns were term and 34% were preterm where as in a study by Sushmita et al., it was 76% term and 24% preterms. In our study 26% neonates had HIE I, 58% were HIE II, 16% were HIE III as compared to another study by Behere A et al., in which 11.3% were HIE I, 72.8% were HIE II and 15.95% were HIE III. In our study 90% of cases had abnormal neurosonogram findings and 10% cases had normal neurosonogram.
