Abstract 202: The Use of Bispectral Index EEG Monitoring as a Screening Tool for the Reliable Detection of Epileptic Activity in Post--Cardiac Arrest Patients

Background: Assessment of prognosis in post[[Unable to Display Character: –]]cardiac arrest (CA) patients became very challenging since the introduction of therapeutic hypothermia (TH). Continuous EEG monitoring has been proposed to improve prognostication; however, its use is limited due to difficulties in readily interpretation. This emerges the need for a simple EEG montage. The bispectral index (BIS) monitor is a simplified EEG system, mainly calculating an index ranging from 0 (isoelectric EEG) to 100 (full consciousness) to provide information on hypnotic depth of anesthesia. The aim of the study was to validate the accuracy of simplified EEG monitoring in a CA - setting. Methods: BIS monitoring (BIS VISTATM) was applied to collect frontotemporal data in TH-treated CA patients. A standard 19 [[Unable to Display Character: –]] channel EEG was performed after return to normothermia. Afterwards, small EEG frames coincident with the time of full EEG registration were extracted from the BIS m...
