ClinConnect Summary
This clinical trial is studying a new way to manage blood flow during major abdominal surgery to help reduce serious complications and improve recovery for high-risk patients. Researchers believe that by personalizing blood flow targets based on each patient's individual needs, they can decrease the chances of problems like kidney injury, heart issues, and infections after surgery. Currently, many patients receive a standard approach, but this trial will compare that method with a personalized strategy to see which one is more effective.
To participate in the trial, patients need to be at least 45 years old and scheduled for elective major abdominal surgery that will last at least 90 minutes. They should also have at least one high-risk factor, such as kidney problems, heart disease, or a history of stroke. Participants can expect close monitoring during surgery and recovery, with their blood flow managed according to their unique needs. This trial is important because it aims to gather more evidence on whether personalized care can lead to better outcomes for patients undergoing significant surgery.
