A Comparison of Renal vs Limb NIRS for Predicting Cardiac Surgery Associated Acute Kidney Injury

ClinConnect Summary

This clinical trial is studying a technology called Near Infrared Spectroscopy (NIRS) to see if it can help predict a complication known as acute kidney injury (AKI) in patients undergoing heart surgery. AKI is a condition where the kidneys suddenly stop working well, and it's a concern for patients having cardiac surgery that requires a heart-lung machine (called cardiopulmonary bypass). The researchers want to find out if placing NIRS sensor stickers over the kidneys can better predict AKI compared to when these sensors are placed on the arms or legs.

To participate in this study, you would need to be an adult aged 18 or older who is scheduled for a heart surgery that involves cardiopulmonary bypass and is at risk for developing AKI. However, those with end-stage kidney disease requiring dialysis, patients needing emergency surgery, or anyone who does not want to participate will not be eligible. If you join the trial, you can expect to have a sensor placed on your skin, and your oxygen levels will be monitored during your surgery to help doctors better understand kidney health during the procedure. The study is being conducted by the University of Utah's anesthesiology department, and they are not yet recruiting participants.
