Our project intends to reduce cardiac surgery associated - acute kidney injury (CSA-AKI) in non emergent patients with the use of an increased adsorption membrane (oXiris®) connected to the cardiopulmonary bypass (CPB) circuit, besides evaluating the inflammatory response by quantifying inflammatory mediators during and after cardiac surgery with CPB. Our study is a randomized and controlled multicentre trial that includes recruiting centres with a long experience in cardiac surgery with CPB. The primary endpoint of the project is to evaluate the ability of oXiris® to reduce the incidence of CSA-AKI in patients undergoing non emergent cardiac surgery with an expected CPB time of more than 90 minutes (doble valve replacement or valve replacement plus coronary artery bypass graft). With the goal of reducing by 10% (from 25 to 15%) the risk of CSA-AKI during the first postoperative week a sample size of 340 patients has been calculated. Secondary endpoints are two; first, to evaluate the effect of using oXiris® on survival, clinical course and removal capacity of cytokines and lipopolysaccharide (LPS) during and after CPB; and second, to assess the predictive value for CSA-AKI of some new biomarkers, such as uNAD (urinary nicotinamide adenine dinucleotide).
