Intervention(s)
The CryoSeal (CS) experimental product consists of two components: cryoprecipitate and thrombin. Cryoprecipitate is one fraction of a single human plasma donation that contains concentrated coagulation factors, such as fibrinogen, which together with the second fraction containing an enzyme thrombin, that facilitating the conversion of fibrinogen into fibrin. Together mixed they will form a clot. This product has two main advantages compared to other current available preparations, namely a single donor-exposure compared to commercial allogeneic fibrin Sealant (FS) products, produced from pooled multiple plasma donations which also has a bovine thrombin source and secondly the controlled hemostatic conditions of the product compared to autologous FS, prepared prior to surgery or at the operation theatre and which content is dependent on its hemostatic condition of patients (age, co-morbidity Based on preliminary estimations on CS use in the literature (1), 12-15 ml CS is expected to be used per patient randomized for CS.
