RATIONALE: In Status Epilepticus (SE), EEG patterns were important regarding to the treatment protocols and prognosis. METHODS: Between 1995-2000, 54 patients (36 female, 18 male; mean age 53)(62 SE episodes) were evaluated with the diagnosis of SE. EEG patterns of patients are classified as discrete, merging, continuous, flattening, irregular flattening, diffuse flattening, supression, burst supression and periodic epileptiform discharges (PED). EEG patterns are additionaly subdivided as generalized and lateralized. RESULTS: Eight of 52 EEGs on admission (15.3%) were classifed as discrete, 19.2% as merging, 65.3% as continuous; 26.9% had also burst supression. Of the 58 EEG's 58% of them were generalized and the remaning 34% were focal. Among the focal EEG's 60% were lateralized to the right hemisphere and the remaning 40% were to the left. 42% of EEG's were normalized after diazepam; 19% after phenytoin; 1.6% after phenobarbital; 1.6% after midazolam; and 1.6% after prophobol. After DZP, epileptiform anomalies improved in 75% of patients with discrete, %66 with merging and %68 with continuous EEG patterns. CONCLUSIONS: According to our findings continuous EEG pattern was the most frequently seen and the most resistance group to antiepileptic treatment in patients with status epilepticus.
