title: Analysis of convulsive status epilepticus in children of Taiwan.
abstract: Convulsive status epilepticus is a medical emergency with significantly associated mortality and morbidity. The demographic data and outcomes of convulsive status epilepticus in children were collected for descriptive analysis. We retrospectively reviewed cases of convulsive status epilepticus in the Pediatric Intensive Care Unit of Chang Gung Children's Hospital between 1999 and 2006. We enrolled 141 patients with 198 episodes of convulsive status epilepticus, aged 2 months to 18 years: 24.8% of first episodes developed convulsive status epilepticus, with a duration of over 60 minutes. First episodes of convulsive status epilepticus were most often evidenced in febrile status during acute central nerve system infections (48.2%), and in nonfebrile status during acute noncentral nerve system illness in previously epileptic children (28.4%). Before their first episode, 63.8% of children were neurologically healthy, and 12.2% exhibited a prolonged febrile seizure. The most common etiology of mortality was acute central nervous system infection. The immediate mortality rate was 7.1%. Convulsive status epilepticus in childhood is more common, with a different range of causes and a lower risk of death, than convulsive status epilepticus in adults. Acute central nervous system infections appear to be markers for morbidity and mortality.
