Suction vs. gravity: which drainage method better protects heart bypass patients?
NCT ID NCT07814573
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
After coronary artery bypass grafting, doctors place tubes to drain fluid from around the heart. This trial compares two ways of monitoring that drainage: using gentle negative pressure (suction) or letting it drain on its own. Researchers will track fluid buildup around the heart, total drainage volume, and complications like irregular heartbeats or bleeding in 400 adults having planned bypass surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- negative-pressure drainage monitoring
- What this could lead to
- If negative pressure works better, it could become a standard way to drain fluid after heart bypass surgery and reduce complications like fluid around the heart.
- What could go wrong
- This is a single-center study of 400 people, so results may not apply everywhere. Negative pressure could also cause more bleeding or other problems, which the trial is designed to detect.
