Summary

This study was designed to see if doctors could predict kidney damage in children after heart surgery by using an ultrasound probe in the esophagus and a light-based oxygen sensor on the skin. The goal was to catch kidney problems early. However, the study was withdrawn before any participants were enrolled, so no results are available.
