Neurodevelopmental outcome of term infants with perinatal asphyxia with hypoxic ischemic encephalopathy stage II

Abstract Background Perinatal asphyxia with hypoxic ischemic encephalopathy (HIE) causes significant mortality and morbidity in developing countries. There is limited information about long term neurodevelopmental outcome of infants with neonatal encephalopathy. Methods Term infants with the diagnosis of perinatal asphyxia were followed up in neurodevelopmental clinics of Manipal Teaching hospital, Nepal. Study design was prospective mixed longitudinal study. Prematurity, major congenital malformations, other intracranial pathology, birth weight Results Total 187 assessments done in the age group of 3 months to 2 years among HIE stage 2 patients. Impaired hearing and vision was noted in 5.3% while language delay was observed in 19.2% of infants. Abnormal tone and deep tendon reflexes were noted in 46.2% infants at 3 months. Abnormal tone and reflexes were noted only in 18.8% and 9.4% respectively at the age of 2 years. Overall, gross motor delay was noted in 55(29.4%) of patient, 34(18.2%) showed fine motor delay and 17.1% social delay. Seizures were persistent in 15.6% patients at 2 years age. Conclusion Infants affected with HIE have delay in all sectors of developmental milestones. Motor abnormalities are common and tend to improve with advancing age.
