Metoderna utförs i helblod och kan alltså anses mer fysiologiska än analyser gjorda på plasma. Metoderna kan detektera Se hela listan på practical-haemostasis.com In general, ED physicians should consider using TEG or ROTEM in any patient with a serious or life-threatening bleed in order to identify coagulopathies that may be corrected. In the setting of trauma, studies have shown that both ROTEM- and TEG-guided treatment algorithms result in non-inferior patient outcomes and result in decreased overall usage of blood products compared to empiric massive transfusion protocols. ROTEM is a modern modification of the TEG technology originally described by Hertert in 1948 [1]. These technologies provide a visual assessment of clot formation and subsequent lysis under low shear conditions (0.1/sec) similar to A normal ROTEM trace: A normal TEG trace The following measurements are shown: R (time of formation of the fibrin strand polymers); K (speed at which the clot forms); (the slope drawn from R to K) and MA (strength of the clot) measurements. Thromboelastography (TEG) and rotational thromboelastometry (ROTEM) are point-of-care viscoelastic devices that use whole blood samples to assess coagulation and fibrinolysis.

Once again, there was no consistent effect on the number of transfusions given, although some studies showed that use of non-TEG/ROTEM studies resulted in fewer units of red cells, platelets, and cryoprecipitate Increasingly, ROTEM and TEG analysis is being incorporated in vertical algorithms to diagnose and treat bleeding in high‐risk populations such as those undergoing cardiac surgery or suffering from blunt trauma. Some evidence suggests these algorithms might reduce transfusions, but further study is needed to assess patient outcomes.

It is a modification of traditional thromboelastography (TEG). This page describes TEG® predominantly, ROTEM® is the alternative viscoelastic hemostatic assay that is widely available commercially METHOD TEG® measures the physical properties of the clot in whole blood via a pin suspended in a cup (heated to 37C) from a torsion wire connected with a mechanical-electrical transducer 2020-12-15 · TEG/ROTEM was no better than non-TEG parameters in predicting the need to transfuse, but did somewhat better than clinical judgement. Once again, there was no consistent effect on the number of transfusions given, although some studies showed that use of non-TEG/ROTEM studies resulted in fewer units of red cells, platelets, and cryoprecipitate given.
Start studying TEG and ROTEM. Learn vocabulary, terms, and more with flashcards, games, and other study tools. TEG and rotational thromboelastometry (ROTEM) are VEAs that assess clot formation, strength, and dissolution by measuring the effect of a continuously applied rotational force on whole blood that is transmitted to an electromechanical transduction system (TEG) or optical detection system (ROTEM), with results displayed as a graph.
