Description
Background
Problem Statement: Postoperative moderate to severe hyponatremia is the most cause of readmission following transsphenoidal endoscopic resection of pituitary tumors, with reported rates up to 8%. The pathophysiology of water balance after pituitary tumor surgery is as below:
[See figure]
Although postoperative diabetes insipidus (resulting in hypernatremia) is a concern in the immediate postoperative period, this is often transient, and thus it has been proposed to implement a postoperative fluid restriction to prevent delayed hyponatremia
