Relationship between serum electrolytes and children febrile convulsion

Objective:To study the relationship between the changes of the concentrations of serum electrolytes and children febrile convulsion(FC).Methods:The concentrations of serum potassium,sodium,calcium,magnesium of 89 children with respiratory tract infec-tion complicated by FC and 80 children with respiratory tract infection were measured,and the relationship between serum electrolytes and FC attack was studied.Results:The concentrations of serum sodium,calcium,magnesium of FC group were significantly lower than those of control group(all P0.01);the concentrations of serum potassium had no significant difference between two groups(P0.05).And the concentrations of serum sodium,calcium,magnesium of FC group had significant difference between one convulsion and two or above(P0.05).Conclusion:The attack of FC is closely related with the concentrations of serum sodium,calcium,magnesium,and is not closely related with the concentration of serum potassium.
