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).
