Ultrasound-guided fluid management during abdominal surgery to prevent complications

During abdominal surgery, doctors need to give patients the right amount of intravenous fluids—too much or too little can cause problems after surgery. This trial is testing a new way to guide fluid management using ultrasound imaging of a large vein in the neck called the internal jugular vein. By measuring how much this vein changes size with breathing, doctors can tell whether a patient needs more or less fluid during the operation.

Many patients experience complications after abdominal surgery because they receive too much or too little fluid during the operation. This treatment offers a simple, non-invasive way to help doctors make better decisions about fluid management in real time, potentially reducing these preventable complications.
