Final answer:
During the removal of a pheochromocytoma, orthostatic hypotension can occur. The management involves monitoring blood pressure, administering fluids, and using vasopressor medications if needed.
Step-by-step explanation:
Orthostatic hypotension can occur during the removal of a pheochromocytoma, which is a tumor of the adrenal medulla that causes excessive production of catecholamines leading to hypertension. The removal of the tumor can result in a sudden decrease in blood pressure, causing hypotension.
The management of hypotension during the removal of a pheochromocytoma involves several steps:
- Monitoring of blood pressure and heart rate to detect changes in blood pressure during the procedure.
- Initiating intravenous fluid administration to maintain adequate blood volume and prevent hypovolemia.
- Administering vasopressor medications, such as phenylephrine or norepinephrine, to increase blood pressure if necessary.
- Continuing close monitoring and management of blood pressure and fluid status during the post-operative period.
