Most patients present with seizures to pediatric emergency department (PED) are observed for extended periods for the risk of possible acute recurrence. The aim of this study is to determine the risk factors of acute recurrence within first 24 h. Patients who presented to PED with seizure during past 24 h were enrolled. Demographic features, number and duration of seizures, diagnostic studies, physical examination findings, presence and time of seizure recurrence in PED were noted. 187 patients were eligible for the study. 46% had recurrence of seizures in 24 h, 90,8% of recurrence within the first 6 h. Univariate analysis showed that younger patients, epileptic patients who were on multiple antiepileptic drugs (AEDs), who had multiple seizures during the past 24 h, who had abnormal neurological examination or neuroimaging findings had increased risk of seizure recurrence. Multivariate analysis showed that number of seizures during the past 24 h and previous use of AEDs was significantly associated with increased risk of recurrence. Risk factors for acute recurrence should be evaluated for each patient. Patients without risk factors and no seizures during the first 6 h should not be observed for extended periods in PED.
