ClinConnect Summary
This clinical trial is looking at how long patients spend on a heart-lung machine, known as cardiopulmonary bypass (CPB), during heart valve replacement surgery and whether this time affects the risk of gastrointestinal complications (GICs), like problems with the stomach or intestines, after surgery. The researchers want to find out if spending more than 120 minutes on the machine increases the chances of these complications and how it impacts recovery for those who do experience them.
To participate, you must be between 18 and 75 years old and scheduled for heart valve replacement surgery that requires CPB. However, certain health conditions or recent surgeries could make you ineligible. If you join the study, you’ll be part of a group that helps us understand these important links between surgery duration and recovery, which could lead to better care for future patients. It’s important to note that the study is still recruiting participants, so there’s an opportunity to get involved if you meet the criteria.
