Abstract

Amplitude-integrated EEG (aEEG) is a commonly used predictor of outcome after hypoxic ischemic encephalopathy. Cerebral and systemic near-infrared spectroscopy and acute kidney injury might also have prognostic value. The authors monitored neonates with aEEG, cerebral and systemic near-infrared spectroscopy during therapeutic hypothermia, assigned an acute kidney injury stage, and measured neurodevelopmental outcome. For 18 infants, cerebral near-infrared spectroscopy variables did not differentiate between those with favorable (n = 13) versus adverse (death or moderate-severe disability; n = 5) 18-month outcomes. However, systemic rSO2 variability was higher during hours 48-72 of cooling among those with favorable outcomes (.02 < P <.03). Mean aEEG amplitude during hours 24 to 48 of cooling was higher among those with good outcomes (.027 < P <.032). The aEEG lower margin was also higher during hours 12 to 48 for those with good outcomes (.014 < P <.035). Acute kidney injury did not predict outcome (P >.05). aEEG is a useful prognostic tool for outcomes after neonatal hypoxic ischemic encephalopathy, but the role of near-infrared spectroscopy in the hypothermia-treated population remains uncertain.
