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.

In order to perform a TEG, a citrated-sample of whole blood is placed into a heated sample cup with calcium chloride (to overcome the effects of the citrate), kaolin (a negatively charged molecule known to initiate the intrinsic pathway 10), and phospholipids (required for optimal functioning of the extrinsic pathway 11) (Figure 2). Effect of thromboelastography (TEG®) and rotational thromboelastometry (ROTEM®) on diagnosis of coagulopathy, transfusion guidance and mortality in trauma: descriptive systematic review.

coagulopathy due to hypothermia.96 TEG/ROTEM has been shown to reduce the transfusion requirement and need of MT in patients undergoing cardiovascular 

Our objective was to review the evidence for their role in diagnosing early coagulopathies, guiding blood transfusion, and reducing mortality in injured Studies investigated TEG®/ROTEM® for diagnosis of early coagulopathies (n = 40) or for associations with blood-product transfusion ( n =25)ormortality(n =24).Most(n = 52) were single-center studies. Techniques examined included rapid TEG® (n =12), ROTEM® (n = 18), TEG® (n = 23), or both TEG® and rapid TEG® (n = 2). Thromboelastography (TEG) evaluates clot initiation, formation, and stability, using whole blood or plasma. TEG has been used primarily to monitor blood component therapy during surgery.

Using 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 Bottom line – There is growing evidence to suggest that the utilization of TEG and ROTEM reduce transfusion requirements and improve morbidity in patients with bleeding, but additional studies are required.

Comparison 4 TEG or ROTEM in combination with SLT or other devices versus clinical judgement or usual ROTEM & TEG can complement one another, when in doubt. Conventional TEG teaching ⇒ if there’s a low α angle, give fibrinogen or platelets; ROTEM FIBTEM system can differentiate between the two conditions to guide transfusion; 10-40-80 rule ⇒ you don’t have to remember PT & PTT or platelet thresholds at 2 in the morning! If FIBTEM A10 Thromboelastography (TEG) is a viscoelastic hemostatic assay that measures the global viscoelastic properties of whole blood clot formation under low shear stress TEG shows the interaction of platelets with the coagulation cascade (aggregation, clot strengthening, fibrin cross-linking and fibrinolysis) But in all my travels, I’ve see very few centers that have fully, effectively, and contemporaneously incorporated TEG or ROTEM into their massive transfusion protocol from start to finish. The area where TEG and ROTEM are most helpful are in the “mop up” phase at the tail end of the MTP. Bottom line – There is growing evidence to suggest that the utilization of TEG and ROTEM reduce transfusion requirements and improve morbidity in patients with bleeding, but additional studies are required. Back to Our Case Why was the trauma surgeon concerned? If we interpret our TEG values: predicting plasma transfusion, and the MA was superior to platelet count in predicting platelet transfusion. These correlations improved for transfused, shocked, or head injured patients.
