Introduction: Traumatic brain injury (TBI) is a common emergency in . The severity of TBI is
determined by the damage as primary or secondary. Secondary injury might change TBI patients
from mild to severe and might become the main cause of death in these ones. Hypernatremia has
been considered as one of the main causes of secondary injury in TBI patients.
Objective: To detect changes of sodium levels in blood of pediatric patients who has TBI and
some factors related to these disorders.
Subjects and methods: A cross-sectional descriptive study, 88 patients in the group of
2months - 15years old. Results: The average rate of dysnatremia was 35%. Hyponatremia
represented 26%, hypernatremia represented 9%. Hypernatremia increases the number of days on
mechanical ventilation. Hypernatremia has a higher rate in the group of patients with severe TBI
(Glasgow ≤ 8 points) and complex injury on computed tomography (CT) of the brain.
Conclusions: Hyponatremia is more common than hypernatremia. However, the prevalence of
hypernatremia is higher in patients with severe TBI. In general, hyponatremia increases the
duration of mechanical ventilation, so it should be diagnosed and treated at the earliest.
