SECONDARY outcome

Timeframe: During initial hospitalization, approximately 7-14 postnatal days

Population: Two infants died during hospitalization and did not have MRI performed.

The National Institute of Child Health and Human Development (NICHD) Neonatal Research Network developed and validated an MRI scoring system that categorizes severity of brain injury in the Trial of Hypothermia for Neonatal Hypoxic-Ischemic Encephalopathy. A higher score is considered a worse outcome. * Score 0: Normal T2 MRI * Score 1A: Minimal cerebral lesions only with involvement of basal ganglia, thalamus * Score 1B: Extensive cerebral lesions * Score 2A: Basal ganglia thalamic, anterior or posterior limb of internal capsule, or watershed infarction * Score 2B: 2A with cerebral lesions * Score 3: Hemispheric devastation

SECONDARY outcome

Timeframe: 18-24 months of age

Population: Bayley-III examinations were planned at the beginning of the study per institutional standard of care. However, during the study period, clinical practice changed, and due to COVID-19 pandemic-related staff turnover, Bayley-III examinations were no longer routinely obtained in Hypoxic-ischemic encephalopathy (HIE) patients. As Bayley-III exams were not included in the study budget and were not a primary study aim, these data were not collected. The protocol was not amended with this change.

The BSID-III is a series of measurements to assess the motor (fine and gross), language (receptive and expressive), and cognitive development of infants and toddlers and consists of a series of developmental play tasks. The composite scores are scaled to a metric with a range of 40 to 160, a mean of 100, and a standard deviation of 15. Therefore, children with a composite score \< 85 are 1 standard deviation below the mean in that area.
