Perioperative Coagulation Management in Cardiac Surgery.

Cardiac surgery is bleeding requiring transfusion surgery . The haemorrhagic is related to the need to use high doses of anticoagulants to prevent thrombosis of blood . Moreover, this type of surgery is platelets and coagulation factors consumming despite conducting a thorough anticoagulation. All these changes contribute to increase the need for transfusions during heart surgery. The main objective of this study is to compare the need for transfusions in patients suffering from bleeding complications after cardiac surgery with a therapeutic algorithm based on the use of ROTEM ® versus standard tests based solely on standard laboratory tests. 100 pateinst (50 in each arm) should be included in this trial.
