The blood volumes needed per each device are as follows: ROTEM Delta, 300 μL per assay; ROTEM Sigma, 3 mL for one cartridge (four assays); TEG 5000, 360 μL per assay; TEG 6S, 400 μL for one cartridge (four assays); Sonoclot, 340‐360 μL per assay; and the ClotPro, 340 μL per assay.

19-28 Both trauma-induced coagulopathy and hemorrhage are strong predictors of Concerning blood transfusions, measurements of clot firmness (ROTEM EXTEM MCF and FIBTEM MCF and TEG MA) and CL (ROTEM LI30 and TEG CL30) were strong indicators of the need for any or massive blood transfusion, particularly for the latter, as well as of plasma transfusion. Que dit la littérature sur le TEG? Cotton, 2011 Étude pilote pour évaluer l’apport des résultats du rapid-TEG, leurs correspondances avec les tests de coagulation habituels (TCA, TP, INR, numération plaquettaire et fibrinogène), et la capacité du TEG à prédire le besoin précoce de transfusion de produits sanguins.

TEG and ROTEM based transfusion strategies have already demonstrated improved outcomes in multiple situations where hemorrhagic complications are encountered, most notably cardiac surgery, liver transplantation, and obstetrics. 17 In cardiac surgery, use of point-of-care viscoelastic testing is associated with reduced rates of transfusion and reduced need for surgical re-exploration. 18 In a Limited evidence from observational data suggests that TEG/ROTEM tests diagnose early trauma coagulopathy and may predict blood-product transfusion and mortality in trauma. The effects of TEG on blood-product transfusion, mortality, and other patient-important outcomes remain unproven in randomized trials. INTRODUCTION: The understanding of coagulopathies in trauma has increased interest in thromboelastography (TEG®) and thromboelastometry (ROTEM®), which promptly evaluate the entire clotting process and may guide blood product therapy. Our objective was to review the evidence for their role in diagnosing early coagulopathies, guiding blood transfusion, and reducing mortality in injured … 2021-03-25 2014-05-21 TEG- and ROTEM-based algorithms have been widely used to direct fibrinogen administration in different settings leading to reduction in transfusion needs, costs, adverse outcomes, and even mortality [13–16] although a recent review indicated that the benefit of reduced blood products (red blood cells, fresh frozen plasma, and platelet) and improved morbidity in bleeding patients with the 2006-08-01 2016-09-01 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.

2017-12-04 · 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 <10 mm ⇒ think cryo
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. A TEG can be used as a rapid assessment of thrombosis and fibrinolysis.

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.

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. TEG-Guided Transfusion As a test of whole blood coagulation, TEG can be used to guide blood product administration. 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. Back to Our Case.
Tromboelastometri och tromboelastografi (ROTEM/TEG) är patientnära koagulationsanalyser, som på bred front introduceras i syfte att styra behandling vid massiv blödning och koagulopati. En systematisk litteraturgenomgång visar att användning av TEG/ROTEM kan sänka transfusionsbehovet vid hjärt- och leverkirurgi.

The ROTEM Delta and cartridge‐based Sigma system (Instrumentation Laboratories, Bedford, MA), the ClotPro device (Enicor, Munich, Germany), and the TEG 5000 (Haemonetics, Braintree, MA) use a traditional viscoelastic method, while the newer cartridge‐based TEG 6S system, the Sonoclot device (Sienco Inc., Morrison, CO), and the Quantra system (HemoSonics, Charlottesville, VA) use a resonance … Practical haemostasis - page on TEG and ROTEM.
