OBJECTIVE: We studied the correlation of duration and frequency of febrile convulsion with peripheral leukocytosis and hyponatremia and identified whether peripheral leukocytosis and hyponatremia to be prognostic factors. METHODS: Two hundred sixty three children who admitted to Pediatric Department of Dongsan Medical Center for febrile convulsion from April, 1999 to March, 2001 were studied. We grouped patients according to the duration of convulsion, daily frequency and total frequency. Body temperature on admission, leukocytes count, platelet count, serum Na level and CSF findings were analysed among the groups. RESULTS: Febrile convulsions occurred more ofthe in males(61%) than females(31%) and most frequently occured in winter(37.2%). There were no meaningful differences in serum sodium concentration and peripheral WBC count among groups according to seizure duration. There were no meaningful differences between groups according to seizure frequency. The protein concentrations of CSF were high in children who developed seizures before 9 months of age(P<0.003). There were no meaningful differences among groups according to seizure types. CONCLUSION: When we compared each group, we could not find any significant statistical correlation. We concluded that peripheral leukocytosis and serum Na level are not predicting factors but they are helpful to find etiology of fever.
