Abstract

The value of the EEG as a predictor of outcome in term infants with hypoxic-ischemic encephalopathy (HIE) was determined in a study at Cork University Maternity Hospital and St Vincent’s University Hospital, Dublin, Ireland.

Highlights

The value of the EEG as a predictor of outcome in term infants with hypoxicischemic encephalopathy (HIE) was determined in a study at Cork University Maternity Hospital and St Vincent’s University Hospital, Dublin, Ireland
EEG is a reliable predictor of neurodevelopmental outcome in term infants with hypoxicischemic encephalopathy (HIE)
In a study at Anjo Kosei Hospital and other centers in Japan, EEG findings varied with the severity of periventricular leukomalacia (PVL) and the timing of recording

Summary

Introduction

The value of the EEG as a predictor of outcome in term infants with hypoxicischemic encephalopathy (HIE) was determined in a study at Cork University Maternity Hospital and St Vincent’s University Hospital, Dublin, Ireland. Of 44 infants who completed follow-up, 20 (45%) had abnormal neurodevelopmental outcomes. Normal/mildly abnormal EEG at 6, 12, or 24 hours had 100% positive predictive values for normal outcome, and negative predictive values of 67% to 76%. At 24 hours, the number of infants assigned to each EEG grade was 6 normal, 11 moderately abnormal, 9 severe, and 3 isoelectric.
