Fludrocortisone evaluation in aneurysmal subarachnoid hemorrhage patients with cerebral salt wasting (Flush Salt).

Objective: Cerebral salt wasting is a condition that can occur in patients with aneurysmal subarachnoid hemorrhage and is characterized by excessive natriuresis, resulting in hyponatremia and hypovolemia. Fludrocortisone is a mineralocorticoid that facilitates retention of sodium and water. Guideline recommendations are weak regarding fludrocortisone use in this patient population due to mixed clinical effectiveness in prior studies.
