TY - JOUR PY - 2010// TI - The prognostic value of early aEEG in asphyxiated infants undergoing systemic hypothermia treatment JO - Acta paediatrica A1 - Hallberg, B. A1 - Grossmann, K.

SP - 531 EP - 536 VL - 99 IS - 4 N2 - Background: Induced moderate hypothermia (HT) for 72 h has been shown to reduce the combined outcome of death or severe neurodevelopmental disabilities in asphyxiated full-term infants. A pathological amplitude integrated EEG background as early as 3-6 h after birth, has been shown to correlate to poor prognosis. Aim: The aim of this study was to investigate the correlation between amplitude integrated EEG during HT treatment and short-term outcome in asphyxiated full-term infants with moderate/severe hypoxic-ischaemic encephalopathy. Methods: Between December 2006 and December 2007, 24 infants were treated with moderate HT (33.5 degrees C for 72 h) using a cooling mattress. Motor functions were assessed at 4 and 12 months of age. Results: Of the total birth cohort of 28,837 infants, 26 infants fulfilled the criteria for HT treatment (0.9/1000) of whom 23 was treated with HT and all of these infants had available amplitude integrated EEG data. Normal 1-year outcome was found in 10/15 infants with severely abnormal burst-suppression pattern or worse at 6 h of age. Severe abnormalities were found to be significantly predictive for abnormal outcome after 36 h. Conclusion: Among asphyxiated infants treated with HT, only those who had aEEG abnormalities persisting at and beyond 24 h after birth showed poor neurological outcome at 1 year.
