SAH and Electrolyte Disorders

Hyponatremia can be seen in up to 40% of patients with a SAH.
Most often, hyponatremia in patients with an SAH is due to SIADH or the cerebral salt wasting syndrome.
To date, hyponatremia has not been associated with poor outcome.
Treatment should focus on the underlying cause and often includes volume replacement with isotonic crystalloids (0.9% NaCl).
