Is it Time to Upgrade Neuromonitoring in ECPR Recipients to Evaluate Cerebral Perfusion Imbalances Adequately?

Abstract Veno-arterial extracorporeal membrane oxygenation (ECMO) brings many monitoring pitfalls due to the countercurrent blood flow, which may create left ventricular overload and perfusion imbalances between the two cerebral hemispheres...

Cerebral Overperfusion Despite Reduced Cortical Metabolism Is Associated with Postoperative Delirium in Cardiac Surgery Patients: A Prospective Observational Study

Abstract Background: Decreased cerebral oximetry (rSO2) in cardiac surgery is associated with postoperative delirium (POD). However, interventions optimizing intraoperative rSO2 are inconclusive.    Methods: In this prospective observational cohort study, the..

Modeling the effect of patient size on cerebral perfusion during veno-arterial extracorporeal membrane oxygenation

Abstract Introduction A well-known complication of veno-arterial extracorporeal membrane oxygenation (VA ECMO) is differential hypoxia, in which poorly-oxygenated blood ejected from the left ventricle mixes with and displaces well-oxygenated blood..
