Summary

This study tested a new way to monitor kidney oxygen levels during liver surgery to try to prevent acute kidney injury (AKI). 80 adults having liver surgery were randomly assigned to either standard care or extra monitoring that triggered a step-by-step treatment plan if oxygen levels dropped. The goal was to see if this approach could reduce the number of patients who develop AKI after surgery.
