A simple choice of IV fluid during surgery could change outcomes — which is safer?

This trial tests two types of intravenous fluids given during abdominal surgery: a standard saline solution and a starch-based fluid. The goal is to see whether one leads to fewer serious complications, such as kidney problems, breathing issues, heart failure, infections, or the need for another surgery, within the first two weeks after the operation. The study includes adults at moderate-to-high risk of complications who are having abdominal surgery lasting at least two hours. By comparing these fluids in a controlled way, the trial aims to find out if the choice of fluid can improve patient safety and recovery.
