Denver developmental screening test II for early identification of the infants who will develop major neurological deficit as a sequalea of hypoxic‐ischemic encephalopathy

BACKGROUND: The primary aim of this study was to find widely available, inexpensive, and non-invasive parameters for early identification or prediction of the infants with hypoxic-ischemic encephalopathy (HIE) who will have a severe adverse outcome (classified as death or a major neurological deficit). METHODS: Fifty-seven full-term or near-term newborn infants with a diagnosis of HIE were consecutively admitted to the neonatal intensive care unit and studied. Occurrence of seizures during the first 24 h, cranial ultrasonography (US) findings within the first 5 days of life, and Denver developmental screening test II (DDST II) at 6 months of age, were analyzed in relation to mortality and neurological status at 2 years of age. RESULTS: Of the 57 infants, 10 were lost to follow-up. Twenty of the remaining 47 infants had a severe adverse outcome. Among the predictors of severe adverse outcome, occurrence of seizures was found to have a poor predictive accuracy. Cranial US had 100% sensitivity, however with a rather low specificity (55%). However, DDST II at 6 months of age, yielded a very high predictive accuracy (sensitivity=100%, specificity=95%). CONCLUSION: We conclude that DDST II at 6 months of age could be used in predicting severe neurological outcome in infants with HIE.
