Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)

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.
