Abstract

PURPOSE
To review the seizure-related complaints and analyze the relationship between admission rates and clinical features in children who had visited the emergency department with seizures.
METHODS
Retrospectively, we reviewed 180 patients(male 100, female 80) suffering from seizures, who had visited to the emergency department of Chosun University Hospital from January 2000 to June 2002. We have analyzed the correlation between admission rate and clinical features such as age, seizure type, seizure duration and individual laboratory findings(CT or MRI, and CSF).
RESULTS
Out of 4,865 total children who visited the emergency department, 180 patients(3.7%) were seizure related. The most common seizure type was simple febrile seizure(52.2%). The admission rate of children with seizures was 48.9%. The admission rate according to age, sex and abnormal laboratory findings revealed no significant correlations(P>0.05). There was a significant correlation between admission and both status epilepticus 82.4%(14/17) and complex febrile seizure 63.6%(14/22) (P<0.05). According to the duration of convulsions, admission rates were 41.2% when within five minutes, 60% when six-15 minutes, 58.8% when 16-30 minutes, 85.7% when 30 minutes, to one hour and 66.7% when above one hour of duration. According to the seizure frequency, admission rates of recurrent seizure patients(61.4%=43/70) was higher compared to the first time seizure patients(40.9%=45/110).
CONCLUSION
We found that the admission rate of children visiting the emergency department for seizure treatment was 48.9% and significantly correlated with duration, type and frequency of seizure.
