|
| E.2.2 | Secondary objectives of the trial |
Assessment of the difference in the response profile of the following parameters:
Blood cell count (EDTA blood sample)
Standard coagulation tests as aPTT, PT, fibrinogen and FXIII
Further ROTEM® parameters
confocal microscopy
Other biological paramaters (thrombingeneration, d-dimers, etc.)

Patients who disagree to participate on the study
for emergency patients: patients with known refusal of a participation in this clinical trial
Active participation in a clinical trial
Any condition, including the presence of laboratory abnormalities, which would place confound the ability to interpret data from the study
Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form
