Continuous EEG monitoring in the follow-up of convulsive status epilepticus patients: A proposal and preliminary validation of an EEG-based seizure build-up score (EaSiBUSSEs)

Continuous electroencephalography (EEG) is a major tool for monitoring patients admitted to the intensive care unit after refractory convulsive status epilepticus, following control of movements. We review values different EEG patterns observed in critically ill prognosis and seizure risk, together with proposed criteria non-convulsive epilepticus diagnosis (Salzburg Criteria), scores (Epidemiology-based Mortality score Status Epilepticus, EMSE) risk (2HELPS2B). These scores, based partially on continuous EEG, are not tailored repetitively monitor progressive build-up leading or recurrence. Therefore, we propose new EEG-based (EaSiBUSSEs), morphology prevalence follow-up patients. It displays subscores from least (no interictal activity) most associated seizures (focal generalized epilepticus). then evaluated performance EaSiBUSSEs cohort eleven who were underwent recording. The receiver operating curve revealed good accuracy identifying would have next 24 h, excellent intra- inter-rater reliability. believe that this simple perform, suitable repeated quantitative description changes seizures.
