Pronostic Value of Gap CO2 During Cardiac Pulmonary Bypass in Cardiac Surgery: a Multicenter Retrospective Study
France318 participantsStarted 2025-02-27
Plain-language summary
Cardiac surgery associated acute kidney injury (CSA-AKI) is one of the most frequent and severe complications after cardiac surgery. The association between acute kidney injury and the mismatch between oxygen consumption and delivery has been well established during cardiopulmonary bypass (CPB) and contributes to the development of CSA-AKI. In this study, the investigators aim to explore the use of gap CO2 during cardiac surgery and its relation with CSA-AKI. In order to explore this association, the invetigators built a retrospective, multicentric study. All patient who underwent cardiac surgery with cardiopulmonary bypass in two French ICU between 03/2019 and 04/2023 and for which information about gap CO2 during CPB is available will be included. After inclusion, patient will be divided in two groups according to the presence or absence of an elevated gap CO2. Occurence of CSA-AKI and other outcomes will be compared between groups, using multivariate analysis.

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?

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?
