Inflammatoire reacties en coagulopathie bij hartchirurgische patienten Inflammation and infection / coagulopathy and disturbed clotting

Interventions

In total 50 patients will be assigned to the intervention group: in this group the autotransfusion reservoir which removes leukocytes and lipids will be used instead of the reservoir not removing le

Design outcomes

Primary

Measure	Time frame
Activation of blood coagulation: erythrocyte-derived and platelet-derived microparticles (EryMP and PMP), are measured because these are known as important activators of coagulation and inflammation, and abundantly present in pericardial blood. Complete blood count : hematocrit (Ht), red blood cells (RBC), platelets (Plt) and leukocytes ( WBC) are markers for the quality of the salvage product. Hemolysis: free hemoglobin (freeHb), potassium (K) and lipid content (triglicerides (TGl), free fatty acids(FFA)) are measured as markers of hemolysis (due to active suctioning of the cell saver and air exposure), and washing efficiency. Red blood cell function: 2,3-diphosphoglycerate (2,3-DPG) will be analysed as a crucial biomarker of the RBC oxygen unloading capacity and therefore as a marker of RBC function of salvaged blood in general. Also, adenosine triphosphate (ATP) will be analysed. ROTEM (ROtational ThromboElastoMetry) and CAT (Calibrated Automated Thrombography) parameters to assess patients coagulation profile.	—
