Summary

This study tested whether a non-invasive light sensor (near-infrared spectroscopy) placed on the skin over the kidney could measure oxygen levels during liver transplant surgery. Researchers monitored 41 patients to see if this method gives useful information about kidney function compared to standard tests. The goal was to find a better way to detect kidney problems early during surgery.
