Status epilepticus was defined as an epileptic seizure or seizures lasting more than 30 minutes or recurring within 30 minutes without recovery of consciousness. The biological investigations performed for all 8 patients included white blood cell (WBC) counts, C-reactive protein (CRP), platelet counts, hemoglobin, asparate aminotransferase (AST), and alanine aminotransferase (ALT), creatinine, base excess, creatine kinase (CK), and cell counts of cerebrospinal fluid (CSF). Serum lactate level was measured in 6 patients. DIC was defined as a decreased platelet count and an increase in fibrinogen/ fibrin degradation production. Metabolic acidosis was defined as base excess (BE) lower than -3 mmol/L. Lumbar puncture (LP) was performed upon admission for all patients except one whose LP was performed at the previous hospital and could not be performed at our center because of the CT findings of moderate cerebral edema.
