Can Partial Oxygen Pressure of Urine be an Indicator for Tissue Perfusion?

Abstract

Objective: None of the advanced monitorisation procedures, which are focusing only on the haemodynamic and blood gas parameters, are sufficient to estimate tissue perfusion adequately. The search for new parameters that are non-invasive and reliable to provide information about tissue hypoperfusion is significant. The purpose of the present study was to evaluate the relationship between urine partial pressure of oxygen (PuO2) and routine systemic tissue perfusion parameters in patients with sepsis-like syndrome and impaired cardiac pressure-volume relationship after an open cardiac surgery.
