Brief summary
Oxiris membrane is an efficient tool for inflammatory cytokines adsorption. Cardiac surgery is followed by an inflammatory state mimicking sepsis. The investigators hypothesized that cytokine adsorption by Oxiris® membrane can attenuate the inflammatory response and thus decrease the microcirculation impairment that followed cardiac surgery.

| Sepsis-related Organ Failure Assessment (SOFA) score with Oxiris® membrane | 30 days | The quick SOFA score (qSOFA) assists health care providers in estimating the risk of morbidity and mortality due to sepsis. The score ranges from 0 to 3 points. The presence of 2 or more qSOFA points near the onset of infection was associated with a greater risk of death or prolonged intensive care unit stay. |
| Simplified Acute Physiology Score (SAPS) II score with Oxiris® membrane | 30 days | SAPS II was designed to measure the severity of disease for patients admitted to Intensive care units aged 18 or more. 24 hours after admission to the ICU, the measurement has been completed and resulted in an integer point score between 0 and 163 and a predicted mortality between 0% and 100%. No new score can be calculated during the stay. If a patient is discharged from the ICU and readmitted, a new SAPS II score can be calculated. This scoring system is mostly used to: describe the morbidity of a patient when comparing the outcome with other patients. describe the morbidity of a group of patients when comparing the outcome with another group of patients |
