Brief Summary

CS-AKI occurring in 20% to 70% of cases depending of the type of cardiac surgery. The systemic inflammatory response is often observed and associated with increased risk of AKI. Cardiopulmonary bypass (CPB) induces a complex inflammatory response that has a multifactorial pathogenesis. The inflammatory response is triggered by exposure of the blood to artificial surfaces during extracorporeal circulation, ischemia/reperfusion injuries, translocation of gram-negative bacteria from the intestinal tract, small amounts of LPS in IV solutions. SIRS during CPB with high levels of inflammatory mediators, active complement proteins and LPS provoke endothelial dysfunction- retraction of endothelial cells with increasing vascular permeability and thrombogenic activity, also inflammatory mediators activate leukocytes and they enhance vascular permeability by affecting endothelial cells and vascular basement membrane. The systemic inflammation and endothelial dysfunction are the basis for multiple organ dysfunction syndrome. Vascular integrity damage during cardiac surgery entail redistribution of fluids with interstitial fluid accumulation and require accurate volume control (pertinent removal of "CPB priming volume"), especially in patients with CKD (low GFR) with high risks of AKI.

Outcome Measures

Primary Outcomes (1)

  • Patient volume status assessment in perioperative period

    To compare volume status in two arms based on CVP mmH2O and PAWP mmHg measurements

    in 24 hours

Secondary Outcomes (2)

  • survival after cardiac surgery

    in 90 day

  • 'ICU and hospital length of stay after cardiac surgery.

    in 28 days

Study Arms (2)

patients undergoing CRRT with oXiris membrane

EXPERIMENTAL

Elective cardiac surgery patients undergoing CPB we will range in 2 groups: I- with Prismaflex set oXiris (SCUF) after CPB, II- standard protocol. Indications for CRRT (SCUF) with oXiris after ICU admission: 1\. Signs of pulmonary edema after cardiac surgery, verified with X-ray control. Or high risk of pulmonary edema after cardiac surgery: 1. Fluid overload ≥ 10%, measured with equation (%fluid overload= ((total fluid in- total fluid out)/admission body weight\*100) 2. CVP (central venous pressure) ˃ 12 mm H2O. 3. PAWP (pulmonary arterial wedge pressure) ˃ 12 mm Hg, measured by Swan-Ganz catheter. In this arm the treatment of fluid overload will be provided via SCUF with oxiris membrane

Device: oXiris membrane
