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).
