Why is adrenal tumor enlarged?

Adrenal tumor patients undergo volume expansion mainly to increase postoperative blood pressure, improve tissue organ perfusion, prevent postoperative complications, etc.

1. To increase postoperative blood pressure,

adrenal tumor secretes a large amount of catecholamines, which will lead to vasoconstriction and increase blood pressure. After tumor resection, catecholamines will suddenly decrease, causing blood pressure to drop sharply and hypotension. Therefore, volume

expansion is needed to increase blood volume and improve tissue organ perfusion.

3. To prevent postoperative complications, volume expansion is required for

adrenal tumor patients before surgery, which can increase blood volume and stability of circulatory system, and help reduce the risk of postoperative complications.
