Intraoperative Renal Near-Infrared Spectroscopy

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.

Multicentre Comparison of Various Microaxial Pump Devices as a Bridge to Durable Assist Device Implantation

This multicentre retrospective study evaluated the effectiveness of different microaxial flow pump (mAFP) devices—mainly Impella CP (3.5 L/min) and Impella 5+ (>5 L/min)—used to stabilize patients with severe heart failure before durable LVAD implantation. High-flow mAFPs were associated with improved hemodynamic support, reduced complications (e.g., renal/liver failure, RVAD use), and better mobilization, although 30-day mortality did not differ significantly between groups.
