Hyponatremia in patients with traumatic brain injury: etiology, incidence, and severity correlation.
Hyponatremia is common in patients with traumatic brain injury (TBI). This study aims at ascertaining the incidence of hyponatremia in TBI with its etiologic diagnosis, biochemical confirmation, and severity correlation with initial Glasgow Coma Scale (GCS) score and computed tomography (CT) abnormality. ⋯ Hyponatremia due to SIADH is more common in TBI. FEUA measurement is not consistent enough to make a distinction between SIADH and CSWS. CT scoring of severity is more predictive of hyponatremia than initial GCS.
