Summary
This study tests a non-invasive ear stimulation technique (taVNS) to prevent acute kidney injury in 152 adults having heart surgery with a heart-lung machine. Half receive real stimulation before and after surgery; the other half get a sham. The main goal is to see if fewer people develop kidney damage within a week.
