AI-Guided fluid drips may cut surgery risks in large trial
NCT ID NCT06011187
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested an artificial intelligence system that helps doctors decide when to give fluids during high-risk abdominal surgery. The goal was to see if using this smart system could reduce serious complications like kidney injury, infections, or heart problems within 30 days after surgery. About 2007 high-risk adults took part in the study across multiple hospitals.
