Abstract
Febrile seizures are common disorders in childhood. We evaluated the serum electrolyte levels and the associated factors in children with single and recurrent febrile seizures in 24 hours period of hospitalization. The medical records of children who were clinically diagnosed with febrile seizures and hospitalized were retrospectively revealed and analyzed. Data were collected for children aged 1 to 6 years including demographic parameters and serum electrolyte levels. A total of 244 children were enrolled in the study in which 209 were diagnosed with single febrile seizures and 35 of them with recurrent febrile seizures. Serum sodium levels were significantly lower in children with recurrent febrile seizure (138.5 ± 2.38 and 134.2 ± 3.55, p < 0.001). Correlation analysis revealed that mild hyponatremia is associated with recurrence of febrile seizure within 24 hours. However, receiver-operating characteristics analysis for hyponatremia showed lower sensitivity (50.3%) and specificity (43.1%) values for optimal cutoff value of 133.5 mmol/L of serum sodium level. Our study suggested that serum sodium levels were significantly lower in children with recurrent febrile seizures. However, because of its lower sensitivity and specificity values, mild hyponatremia cannot be used as an indicator for febrile seizure recurrence.
