Clinical Trial Summary

The purpose of the study is to describe the differences in measurements of viscoelastic tests of coagulation by two different devices in adult trauma patients.

Description:

The study will commence following the Approval by The Ethics Research Committee. All patients admitted to our emergency department for trauma from the 1st of October 2019 to the 31st of January 2020 will be enrolled after fulfilling the inclusion criteria and in the absence of any exclusion criteria. Informed consent will be requested. Viscoelastic tests of coagulation will be performed on ROTEM® Delta and ClotPro® simultaneously. We will compare values of clotting time (CT), clot formation time (CFT), alfa angle, maximum clot firmness (MCF) and maximum lysis (ML) for test of extrinsic pathway(EX-test) on ClotPro® vs. test for extrinsic pathway (EXTEM) on ROTEM® Delta. Further we will compare values of clotting time (CT), clot formation time (CFT), alfa angle, maximum clot firmness (MCF) and maximum lysis (ML) for thromboelastometry of fibrinogen (FIB-test) on ClotPro® vs. thromboelastometry of fibrinogen (FIBTEM) on ROTEM® Delta. The secondary outcome will be to describe the dependence of measurement on temperature of patient. Study data will be entered in study form. The measurements can be repeated in time. The indication for next measurement is fully on treating physician. Differences in estimated viscoelastic coagulation parameters will be analysed.
