E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
ROTEM SUBSTUDY, Thrombelastography/Thrombelastometry allows an overall assessment of hemostatic function. It provides a graphic representation of both, clot formation and lysis. Rotation thrombelastometry (ROTEM) is now widely accepted as point-of-care assessment of the viscoelastic clot strength in whole blood and is thus regarded as a clinically relevant model to investigate both coagulation and fibrinolysis [Gallimore et al, 2005]. ROTEM has been shown to detect changes in fibrinolysis in humans [Spiel et al, 2006]. The objectives of the ROTEM substudy are to determine parameters of coagulation and fibrinolysis in whole blood over the course of surgery and study drug administration. The substudy is part of the protocol TMC-MDC-11-01 Version 2.0, Date 31.10.2011
