The IKORUS system (Vygon, Écouen, France) allows continuous monitoring of the urethral perfusion index (uPI) using a photoplethysmographic sensor mounted near the base of the balloon of a dedicated urinary catheter. We aimed to test the hypothesis that the uPI decreases during off-pump coronary artery bypass (OPCAB) surgery and to investigate the relationship between the uPI and macrocirculatory variables. Prospective observational study.
Hypotension during induction of anaesthesia is associated with organ injury. Continuous arterial pressure monitoring might help reduce hypotension. We tested the hypothesis that continuous intra-arterial compared with intermittent oscillometric arterial pressure monitoring reduces hypotension during induction of anaesthesia in noncardiac surgery patients.
‘Surgery went well, and everything is fine. Your relative is still in the operating theatre, but you can visit this afternoon on the ward’. Each day, thousands of patient families receive relieving calls like this. A call better reflecting clinical reality would be, ‘Surgery went well, and everything is fine so far, but the most dangerous time is still ahead. The postoperative period poses a much higher risk for patients than surgery itself’.
