|---|---|---|---|---|---|---|
| NCT00131040 ↗ | Investigation of Leukocyte Trafficking Into Skin Blisters During Cardiopulmonary Bypass | Completed | British Heart Foundation | N/A | 2003-01-01 | The purpose of this study was to see if the heart-lung machine involved in cardiac surgery increases the movement of activated white blood cells from the bloodstream into the patient's tissues and also to see if aprotinin usage during surgery reduces this effect. |

| NCT00214656 ↗ | "Salvage Use" of Recombinant Factor VIIa After Inadequate Haemostasis in Complex Cardiac Surgery | Unknown status | Austin Health | Phase 3 | 2005-06-01 | Aims and Hypotheses: This randomised placebo controlled study will test the hypothesis that Recombinant Activated Factor VII (rVIIa) will improve haemostasis after an inadequate response to conventional therapy in complex cardiac surgery. Major bleeding is still of concern in complex cardiac surgery. It has been shown to be associated with poorer patient outcome and results in the consumption of resources (hospital costs, manpower and blood bank reserves). This study has the potential to provide evidence that rVIIa can reduce transfusion requirements and improve patient outcome in a problematic aspect of complicated cardiac surgery. The objective is to conduct a multi-centre randomised placebo controlled study that has been designed to scientifically evaluate the treatment of post bypass coagulopathy in the association with complex cardiac surgery. The trial design is based on clinical practice that has evolved over 2 years at the Austin Hospital during which 38 patients have received open label administration of rVIIa. There is currently no published RCT in this area and there is no TGA approval for the use of rVIIa for this indication. |
| NCT00223704 ↗ | Bradykinin Receptor Antagonism During Cardiopulmonary Bypass | Completed | Vanderbilt University | Phase 2/Phase 3 | 2006-05-01 | Each year over a million patients worldwide undergo cardiac surgery requiring cardiopulmonary bypass (CPB). CPB is associated with significant morbidity including the transfusion of allogenic blood products, inflammation and hemodynamic instability. In fact, approximately 20% of all blood products transfused are associated with coronary artery bypass grafting procedures. Transfusion of allogenic blood products is associated with well-documented morbidity and increased mortality after cardiac surgery. Enhanced fibrinolysis contributes to increased blood product transfusion in the perioperative period. The current proposal tests the central hypothesis that endogenous bradykinin contributes to the hemodynamic, fibrinolytic and inflammatory response to CPB and that bradykinin receptor antagonism will reduce hypotension, inflammation and transfusion requirements. In SPECIFIC AIM 1 we will test the hypothesis that the fibrinolytic and inflammatory response to CPB differ during ACE inhibition and angiotensin II type 1 receptor antagonism. In SPECIFIC AIM 2 we will test the hypothesis that bradykinin B2 receptor antagonism attenuates the hemodynamic, fibrinolytic, and inflammatory response to CPB. In SPECIFIC AIM 3 we will test the hypothesis that bradykinin B2 receptor antagonism reduces the risk of allogenic blood product transfusion in patients undergoing CPB. These studies promise to provide important information regarding the effects of drugs that interrupt the RAS and generate new strategies to reduce morbidity in patients undergoing CPB. |
