Non-invasive Evaluation of Fluid Status and Cardiac Output During Operative Treatment of Pheochromcytoma

Austria15 participantsStarted 2011-08

Plain-language summary

Non-invasive measurements of cardiac output (CO), systemic vascular resistance (SVR), corrected aortic flow time (FTc) and stroke volume (SV) are useful parameters during laparoscopic resection of pheochromocytoma (adrenalectomy) to document the intraoperative changes in volume status and to estimate the volume depletion.

Inclusion Criteria: * Planned laparoscopic adrenalectomy for pheochromocytoma (Biochemical confirmed adrenal and extraadrenal pheochromocytoma) * Planned laparoscopic adrenalectomy for hormonally inactive adrenal tumor Exclusion Criteria: * Risk of esophageal bleeding or perforation exists (i.e., liver disease with portal hypertension and/or esophageal varicoses, other esophageal anomalies).

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
