Abstract

LOPEZ, Marina Sol et al. Thromboelastography and Thromboelastometry. Acta bioquím. clín. latinoam. [online]. 2016, vol.50, n.2, pp.291-301. ISSN 0325-2957.

Thromboelastography (TEG) and thromboelastometry (TEM) describe the interaction between coagulation factors, fibrinogen, platelets and members of the fibrinolytic system in whole blood, in real time, assessing the kinetic and viscoelastic characteristics of the clot formed. TEG was described many decades ago, but the introduction of new instruments, thromboelastograph and rotational tromboelastometers, using agonists to activate the coagulation system that reduced time for results and software that allowed for the analysis of parameters, transformed these tests into useful tools in the management of the bleeding. In recent years, the literature has increased over the use of these tests for transfusion management in situations such as trauma, surgery, and post-partum bleeding. The present update will be describing these tests, their interpretation and usefulness.

Keywords : Hemostasis; Thromboelastometry; Thromboelastography.
