Abstract

OBJECTIVE: Prognostication in patients with post-hypoxic brain injury remains difficult; yet, clinicians are commonly asked to guide decisions regarding withdrawal of life support. We aimed to assess whether electroencephalogram (EEG) is a useful tool in predicting neurological outcome in patients with post-hypoxic myoclonus (PHM). DESIGN AND SETTING: This study was conducted as part of an internal hospital audit assessing therapeutic hypothermia in patients with hypoxic cardiac arrest. PARTICIPANTS: We identified 20 patients with PHM and evaluated their initial routine EEG. MAIN OUTCOME MEASURES: Three blinded neurologists independently assessed EEGs and scored them using the standardised c..
