Overview
Brief Summary
This study is planned to investigate the relationship between duration of extracorporeal circulation and the extent of (acquired) platelet dysfunctions in patients undergoing cardiac surgery.
Detailed Description
Patients undergoing complex cardiac surgery are planned to be included. At several intra- and postoperative measuring point, blood is drawn for multiple electrode aggregometry to investigate ex-vivo platelet aggregation as a surrogate for platelet function. Transfusion rate of allogenic blood products as well as postoperative blood loss is planned to be recorded.
