Sep 24, 2020 VHAs, particularly TEG, may reduce mortality and reduce transfusion exposure and, if available, may be considered for transfusion guidance in

Thromboelastography (TEG ®; Haemonetics Corporation, Braintree, MA, USA) and rotational thromboelastometry (Rotem ®; Tem International GmbH, Munich, Germany) provide the continuous measurement and display of the viscoelastic properties of a whole blood sample from the initial phase of fibrin formation to clot retraction and ultimately fibrinolysis. 2

Guideline recommendations r We recommend that platform-specific guidelines be used for specific TEG/ROTEM In trauma, both TEG and ROTEM have similar clinical performance for prediction of mortality and transfusion requirements.12. The ability to detect hyperfibrinolysis guide hemostatic therapies, and to predict the risk of bleeding during the The TEG/ROTEM® assess the viscoelastic properties of blood samples under low Transfusion in Trauma Guidelines proposed by the American. College of It is another VEM the process of which is similar to ROTEM and TEG. The Sonoclot 21 Dec 2016 In order to perform a TEG, a citrated-sample of whole blood is placed into the utilization of TEG and ROTEM reduce transfusion requirements 4 Feb 2020 TEG results showed recovery of coagulation time (R) in both kaolin assay (CK) (TEG) or rotational thromboelastometry (ROTEM), have recently attracted According to the guidelines for hemostasis strategy for patients 11 Sep 2018 Blood product transfusion in the Pre-ROTEM group was guided by hypofibrinogenemia of varying degrees and provided a guide for the transfusion of CrossRef; Whiting D., DiNardo J.

A representation of various clotting functions over time is provided as different graphs, which are interpreted and guide treatment. Once therapy is initiated, it is advisable to repeat the ROTEM/TEG to determine if interventions are effective and clotting profiles normalise. Yet again, EAST conditionally recommended use of TEG/ROTEM in these patients despite the very low level of evidence. Again, this is mainly because of the lack of perceived harm in using it, and the possibility that it might reduce exposure to blood products. Bottom line: Hmm. I remain skeptical. ROTEM and TEG were performed simultaneously in the same patients within 30 minutes of admission and repeated when clinically indicated during the first 12 hours. The tests were done conventionally, according to the manufacturer's instructions.

TEG and ROTEM: Technology and clinical applications David Whiting and James A. DiNardo* Initially described in 1948 by Hertert thromboelastography (TEG) provides a real-time assessment of viscoelastic clot strength in whole blood. Rotational thromboelastometry (ROTEM) evolved from TEG technology and both

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.

A 24 minute overview on ROTEM, TEG. Topics covered include a historical background to ROTEM, the evidence for it, how to interpret and run the test, future s TEG-based algorithms appear to favour the use of FFP; In liver transplantation (Coakley et al, 2006), TEG and ROTEM transfusion algorithms tend to agree in everything except the decision to give FFP (they were in agreement regarding platelet transfusion and cryoprecipitate). 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 patients. UK NEQAS data suggests coefficients of variance ranging from 7.1% to 39.9% for TEG® and 7.0% to 83.6% for ROTEM® may require specialist staff to perform; EVIDENCE. Cochrane review (2015)of the use of TEG and ROTEM in traumatic bleeding advised that they should be used for research only, due to a lack of evidence for the accuracy of the assays.

An attempt should be made, if possible, to correct significant coagulopathy by administering frozen plasma (FP), platelets, cryoprecipitate and vitamin K. Correcting pre-existing coagulopathy prior to initiation of ECLS may In my last post, I explained why TEG is not so easy to use. Today, I’ll share the new Eastern Association for the Surgery of Trauma (EAST) practice management guidelines for using TEG and its twin, ROTEM for bleeding patients.
