Clinical Trial Summary

Recently, the investigators study group showed in a mono center study that Point of Care (POC) based hemotherapy may reduce transfusion rates of allogenic blood products in perioperative care of coagulopathic cardiac surgery patients. The investigators aim to verify the obtained results by conducting this multicenter study.
