Prolonged continuous EEG recordings from term neonates with HIE during therapeutic hypothermia enrolled in a prospective observational study were examined. Adverse outcome was defined as death or severe brain injury by magnetic resonance imaging (MRI); favorable outcome was defined as normal or mild injury by MRI. Neonates were stratified by Sarnat grade of encephalopathy at admission. EEG was partitioned into 10-minute nonoverlapping artifact- and seizure-free epochs. Delta power was calculated and compared between the groups using receiver operating characteristic (ROC) analyses and Wilcoxon rank-sum tests. An area under the ROC curve &gt;0.7 with P &lt;.05 was considered a significant separation between groups. The favorable outcome group (n = 67) had higher delta power than the adverse outcome group (n = 28) across the majority of time periods from 9 to 90 hours of life. Delta power discriminated outcome groups for neonates with moderate encephalopathy (63 favorable and 14 adverse outcome) earlier in cooling (9-42 hours of life) than neonates with severe encephalopathy (21-42 hours of life). Outcome groups were differentiated after 81 hours of life in neonates with moderate and severe encephalopathy. Delta power can distinguish cooled HIE neonates with adverse outcome independently of the encephalopathy grade at presentation. Delta power may be a real-time continuous biomarker of evolving encephalopathy and brain injury\/death in neonates with HIE.<\/jats:p>","DOI":"10.1177\/0883073820915323","type":"journal-article","created":{"date-parts":[[2020,4,20]],"date-time":"2020-04-20T03:49:53Z","timestamp":1587354593000},"page":"517-525","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":31,"title":["Prognostic
