Skin tone will be assessed using the Monk scale. Prior to induction of general anesthesia, the right kidney will be located by surface ultrasound, the distance between the renal capsule and the skin will be measured, and a NIRS sensor will be placed on the skin overlaying the kidney. If the patient has had a right nephrectomy, the left kidney will be used. Additional NIRS sensors will then be placed over the patient's ipsilateral biceps and vastus lateralis muscles. The distance from the skin to the muscle tissue will be measured and recorded using ultrasound. NIRS sensors will also be placed on the patient's forehead to measure cerebral oximetry as is current practice at our institution for all cardiac surgeries requiring cardiopulmonary bypass.",[9],[21],{"name":22,"affiliation":5,"role":23},"Natalie Silverton, MD","PRINCIPAL_INVESTIGATOR",[25,29],{"name":22,"role":26,"phone":27,"phoneExt":10,"email":28},"CONTACT","801-581-6393","natalie.silverton@hsc.utah.edu",{"name":30,"role":26,"phone":31,"phoneExt":10,"email":32},"Natalie Bennion, MPH","801-585-7697","Natalie.Bennion@utah.edu",[34],{"facility":5,"status":35,"city":36,"state":37,"zip":38,"country":39,"countryCode":40,"cosmosGeoPoint":41,"geoPoint":46,"contacts":47},"RECRUITING","Salt Lake City","Utah","84132","United States","US",{"type":42,"coordinates":43},"Point",[44,45],-111.89105,40.76078,{"lat":45,"lon":44},[48],{"name":22,"role":26,"phone":27,"phoneExt":10,"email":28},{"type":23,"investigatorFullName":50,"investigatorTitle":51,"investigatorAffiliation":5,"oldNameTitle":10,"oldOrganization":10},"Natalie Silverton","Associate Professor of Anesthesiology","100570331","a-comparison-of-renal-vs-limb-nirs-for-predicting-cardiac-surgery-associated-acute-kidney-injury-100570331",false,"NCT06705855","A Comparison of Renal vs Limb NIRS for Predicting Cardiac Surgery Associated Acute Kidney Injury","Inclusion Criteria:\n\n* We will enroll a convenience sample of adult cardiac surgery patients undergoing procedures that require cardiopulmonary bypass (CPB) and who are at risk for AKI.\n\nExclusion Criteria:\n\n* Exclusion criteria will include less than age 18 years old, preoperative end-stage kidney disease requiring dialysis, emergency surgery, or patient refusal.","ALL","18 Years",{"count":61,"type":62},100,"ESTIMATED","30 Days","OBSERVATIONAL","Acute kidney injury (AKI) is a complication of cardiac surgery that can affect outcome. Near Infrared Spectroscopy (NIRS) is a technology that uses light to determine how well oxygenated tissues are. This technology is routinely used in cardiac surgery to measure the oxygen level in the brain by placing a sensor sticker on the forehead. The purpose of the study is to determine whether NIRS sensor stickers placed on the skin over the kidney can predict AKI better than when sensors are placed on the skin over the participant's limbs. This study is being conducted by investigators from the department of anesthesiology at the University of Utah.",[67,68,69,70],"NIRS","Cardiac Surgery Associated - Acute Kidney Injury","Cardiac Surgery Requiring Cardiopulmonary Bypass","AKI - Acute Kidney Injury",[72],"Cardiovascular","2025-08-12",{"date":75,"type":76},"2025-08-17","ACTUAL",{"date":78,"type":76},"2025-05-29",{"date":80,"type":62},"2026-08-30",{"name":5,"class":6},1]
