The Urethral Perfusion Index During Off-Pump Coronary Artery Bypass Surgery: An Observational Study
Authors' conclusion
The uPI decreases during OPCAB surgery, specifically during the cardiac positioning phase. There was no clinically important association between uPI and either cardiac output, mean arterial pressure, or heart rate.
