Omitting preoperative alpha-blockade for normotensive pheochromocytoma

Official title: A Pilot Study for Randomized Controlled Trial on the Effect and Safety of Omitting Preoperative Alpha-adrenergic Blockade for Normotensive Pheochromocytoma

Run by Seoul National University Hospital · NCT05702944 · Data updated 2026-11-12

This study is testing whether skipping a common medication before surgery can help patients with certain tumors avoid low blood pressure during and after their operation without putting them at risk.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients aged 19 to 70 years undergoing unilateral total adrenalectomy for normotensive pheochromocytoma or paraganglioma.

Probably not a fit

Patients with hypertension, those requiring intensive care, or those with a history of severe cardiovascular issues may not benefit from this study.

What this trial studies

This clinical trial investigates the safety and effects of not using preoperative alpha-adrenergic blockade in patients undergoing surgery for normotensive pheochromocytoma and paraganglioma. The study aims to determine if avoiding this routine treatment can reduce the risk of perioperative hypotension without compromising patient safety. Participants will be monitored for hemodynamic stability during and after their surgical procedures. The trial focuses on patients who meet specific criteria, including age and health status, to ensure a controlled environment for assessing outcomes.

Why it matters

Potential benefit: If successful, this approach could lead to safer surgical procedures for patients with normotensive pheochromocytoma, reducing the need for preoperative medications.

How similar studies have gone: While there is ongoing debate regarding preoperative management in similar cases, this specific approach of omitting alpha-blockade is relatively novel and has not been extensively tested.
