EFFICACY OF EMERGENT ELECTROENCEPHALOGRAPHY (EMEEG) IN DETECTING NONCONVULSIVE SEIZURES.

Introduction: Identification of non-convulsive seizures is important in neuro critical care practice. Emergent basis Electroencephalography (EmEEG) may helpful in detecting non-convulsive seizures and its medical management. Objective: To assess the yield of EmEEG in detecting non-convulsive seizures. Methods: Study was conducted in a tertiary level super specialty hospital. All patients entered in the emergent EEG register from June 2012 to December 2016 were included. 32 channels Digital EEG (Natus neurology, Canada) was used to perform EEG. Electrodes were placed according to 10-20 system. Clinical history, provisional diagnosis and other lab reports were analyzed. Results: A total of 400 EEGs were analyzed. 40(10%) patients showed periodic complexes, 33(8.3%) patients showed non convulsive seizures, 20(5%)patients showed non-convulsive status epilepticus, 13(3.3%) patients showed complex partial seizures, 4 (1%) patients showed statusepilepticus and 38(9.5%) patients showed inter ictalepileptiform abnormalities. On the whole, out of 400 patients; 53 (13.25%) showed non-convulsive seizures. Conclusion:Emergent EEG has a major role in detecting non-convulsive seizures and neuro-crtical care management.
