Etiology of a short-term mortality in the group of 750 patients with 920 episodes of status epilepticus within a period of 10 years (1988–1997)

PurposeTo determine the etiology of short-term mortality in patients with status epilepticus (SE).Methods920 episodes of SE were recorded among 750 patients in a 10-year period. According to the clinical assessment, sequence of events that led to death in a particular case showed two major causes of death: (1) underlying disease, and (2) complications caused by convulsions, therapy or coma.ResultsAmong 920 episodes of SE, 120 (13%) patients passed away. 79 patients (65.8%) died due to the underlying disease and 27 patients (22.5%) died of the combination caused by complications of underlying disease, convulsions, therapy, and/or coma. Among remaining 14 patients (11.7%), underlying disease was not the cause of death. Those 14 patients suffered complications caused by convulsions, therapy, and coma which caused death in four; therapy and coma in three; therapy in three; coma in two; and convulsions and coma in two patients, in the order already mentioned.ConclusionsAmong approximately 9 out of 10 patients with SE, death was the result of underlying disease. Although with very few patients, additional factors could provoke fatal complications of SE. In case of 1 among 10 patients complications caused by coma, therapy, and/or convulsions were the immediate cause of death. In case of such patients timely and adequate treatment could prevent death.
