In this study, the incidence among children hospitalized hypernatremia, causes, development time, clinical features, and morbidity, and aimed to reveal the effect on mortality.Material and Methods:In this retrospective study, clinical and laboratory data from patients with hypernatremic were recorded. The study period was 33 months. The groups were separated into two groups; group I: Hypernatremia was present at hospital admission, group II: Hypernatremia was acquared after the hospitalization.Results:Overall incidence of hypernatraemia was 1.3% of all hospitalised children. While 42% of patients were from group I, 58% of patients had acquired hypernatremia during hospital stay. In group I, 61% of patients had infections on hospital admission. The most common cause of hypernatraemia in group II was neurological disorders (53%). The mortality rate was 30.5% (11/36) in patients with hypernatraemia on admission, 67.3% (33/49) in those with hospital-acquired hypernatraemia (P 0.05.Conclusions:Hypernatraemia in pediatric age is associated with mortality and morbidity, and should be closely monitored in pediatric patients hospitalized for any reason in order to prevent complication.
