Intraoperative Renal Near-Infrared Spectroscopy Monitoring as a Predictor of Renal Outcomes in Cardiac Surgery
This study assessed whether intraoperative renal near-infrared spectroscopy (NIRS) could predict acute renal failure (ARF) in 357 cardiac surgery patients. It found that longer durations of reduced renal oxygenation (rSO₂) below 80%, 70%, and 60% thresholds were significantly associated with ARF development. NIRS monitoring showed high sensitivity and specificity, indicating its potential for early detection and intervention during surgery.
