Abstract

OBJECTIVE: To evaluate the role of Resistive index measured by cranial doppler ultrasonography in predicting the risk of death/ abnormal neurodevelopmental outcomes in term neonates with hypoxic ischemic encephalopathy. METHODS: We enrolled 50 term asphyxiated neonates with hypoxic ischemic encephalopathy and measured resistive index within 72 hours from the anterior cerebral artery. Participants underwent tone and developmental assessment at 6-12 months. RESULTS: Among the 50 neonates, 25 (50%) had abnormal resistive index (<0.56 or >0.80). Presence of abnormal resistive index increased the risk of death/ abnormal neurological outcomes at 6-12 months [RR (95% CI): 7.5 (2.0,8.6), P<0.01]. CONCLUSION: An abnormal resistive index is associated with death/ neurodevelopmental impairment in neonatal hypoxic ischemic encephalopathy.
