Background: Simple febrile seizures are the most common type of childhood seizures . The objective of the present study was to determine the role of serum sodium levels in predicting seizure recurrence within 24 hours and recurrent episodes of febrile seizures in children. Materials and Methods: It is a cross – sectional study, performed on 100 children with febrile seizures aged between 6 months –60months, admitted to the department of Paediatrics of MOSC medical college, Kolenchery for a period of one year. Results: Out of 100 children, 33 % had recurrences in 24 hours and 16% had recurrent episodes. Only 31% had sodium level below 130mmol/l and out of that, 29 had seizure recurrence within 24 hours, which was not statistically significant. The sodium levels of 16%children who had recurrent episodes of seizure, was also between 130.1–135mmol/l. No significant differences were seen between the serum sodium levels in simple febrile seizures and recurrent episodes. Conclusion: Overall analysis showed that low serum sodium levels was not statistically significant to predict a seizure recurrence within 24 hours, but a relative hyponatremia can predispose a febrile child to occurrence of simple febrile seizure.
