Hyperoxia vs Normoxia During Cardiopulmonary Bypass

Italy104 participantsStarted 2025-07-01

Plain-language summary

This single-center randomized controlled pilot trial evaluates the effects of intraoperative hyperoxia compared with normoxia during cardiopulmonary bypass (CPB) in adult patients undergoing elective cardiac surgery. The primary aim is to assess the impact on postoperative renal function. Secondary outcomes include inflammatory markers, cardiovascular and pulmonary complications, resource utilization, and short-term mortality.

Inclusion Criteria: * adult patients (\>18 years old) * need for elective cardiac surgery requiring CPB (i.e., isolated valve repair/replacement, coronary artery bypass grafting, or ascending aorta surgery) * Time frame from July 1st to September 15th 2025 Exclusion Criteria: * refusal of consent, * pregnancy, * previous Intensive Care Unit (ICU) admission, * history of cardiac surgery requiring CPB, * signs of preoperative cardiogenic shock (defined as requiring inotropic support, intra-aortic balloon pump, or other mechanical circulatory assistance), * intraoperative need for circulatory arrest.

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.
