Abstract

Background AND PURPOSE: Status epilepticus (SE) is one of the major neurological emergency that requires immediate treatment to avoid significant morbidity and mortality. Thus, understanding the cause, features and prognosis of SE is important for the evaluation and treatment of this condition. We retrospectively reviewed the possible cause and clinical outcome of adult patients treated for SE at the Hallym Univrsity Hospital from 1994 to 1998.
METHODS
For the identification of patients, we searched the data bank for patients meetinf criteria of SE who were 18 year or older, and their medical records were reviewed. We also investigated the relationships between cause, response to anticonvulsant therapy and short-term clinical outcome.
RESULTS
The selected 127 patients wer 84 males and 43 females, aged 18 to 85 yeats (meen age: 49.5 years). The possible etiologies of SE were withdrawal of AED (n=27, 21.3%), anoxia (n=22, 17.3%), CNS infection (n=20, 15.7%), stroke (n=16, 12.6%), alcohol-related (n=15, 11.8%), metabolic (n=8, 6.3%), unknown (n=7, 5.5%), drug inroxicatio (n=5, 3.9%), trauma (n=4, 3.2%) and cerebral tumor (n=3, 2.4%). in 77 patients (n=77, 60.6%), SE was successfully aborted with first-line therapy, which usually included diazepam with or without phenytoin. The food responders to AEDs occurred in patients with AED withdrawal, alcohol-related, stroke, unknown, and trauma, The poor response related to anoxia, drug intoxication and CNS infection. Seventy nine patients (62.2%) had food outcome, but nineteen patients (14.9) were died. Anoxia, drug intoxication, CNS infection and metabolic abnormalities were associated with particularly poor outcome compared with other etiologies.
CONCLUSION
This study indicates that the etiology of SE may help predict both the intial response to drug therapy and short-term clinical outcome.
