Brief Summary
Assessment of high-normal dosage of Wilate ® compared to placebo administered in combination with platelets to assess reduction of amount of blood loss, need of transfusion products and outcome (length of stay, mortality) in patients with bleeding in comparison.

Study Arms (2)
Platelet transfusion with Wilate ®
EXPERIMENTALPlatelet transfusion with Placebo
PLACEBO COMPARATORInterventions
Wilate ® will be given with platelets in cases of severe bleeding. Wilate ® is a 1:1 balanced mixture of von Willebrand Factor (2'000 IU) and Coagulation factor VIII (2'000 IU) and as such has anti-haemorrhagic potential. It is extracted from plasma, freeze-dried and virus-inactivated.
Empty placebo will be given with platelets in cases of severe bleeding.
