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.

Increasingly, ROTEM and TEG analysis is being incorporated in vertical algorithms to diagnose and treat bleeding in high-risk populations such as those

The examiners referred to TEG specifically in the question and throughout the answer, but it is clear that they were using the term interchangeably with ROTEM, and so in the discussion to follow TEG is also used as a surrogate for all forms of global testing for clotting function. 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 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. Am. J. 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. Direct comparison of TEG ® and ROTEM ®. The literature search identified 191 studies, of which only 4 directly compared TEG ® with ROTEM ® and none were done in trauma.

Comparison 4 TEG or ROTEM in combination with SLT or other devices versus clinical judgement or usual 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 When comparing suggested blood products using our TEG decision tree and an Intem based decision tree, both devices had the best agreements on transfusion of no products as guided by conventional tests, but lower agreement with abnormal conventional tests that would have resulted in blood component transfusion based on low fibrinogen levels (TEG and ROTEM- 0%), low platelets (TEG 44.4%, ROTEM Thromboelastography (TEG) is a method of testing the efficiency of blood coagulation.It is a test mainly used in surgery and anesthesiology, although increasingly used in resuscitations in Emergency Departments, intensive care units, and labor and delivery suites. Differences were observed between TEG and ROTEM on the probability of tPA induced lysis detection. The lowest study concentration with sensitivity levels above 70% for Lysis prediction versus reference range was 60ng/ml for CK.LY30 and CRT.LY30, 80ng/ml for EXTEM.LI30 and 100ng/ml INTEM.LI30. 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.

Sammanfattningsvis har TEG/ROTEM följande teoretiska fördelar jämfört med standardkoagulationsanalyser: Metoderna kan utföras bedside, och svar kan ges inom 15 minuter. Metoderna utförs i helblod och kan alltså anses mer fysiologiska än analyser gjorda på plasma. Metoderna kan detektera

TEG is T hrombo E lasto G raphy, and ROTEM is RO tational T hrombo E lasto M etry, both acronyms being registered trademarks. Both are tools of assessing whole blood clotting. Whole blood (a miniute amoutn of it, no more than 1ml) at body temperature (37º) is added to a heated cuvette (a little cup).

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. 2014-08-19 · TEG and ROTEM Thromboelastography (TEG) and rotational thromboelastometry (ROTEM) are both laboratory methods for testing how well the blood coagulates. Rather than measuring the function or concentration of specific components of the coagulation pathways, like the PT or aPTT do, TEG and ROTEM measure the functional abilities of the overall coagulation pathways. Thromboelastography [TE] was first described by Hartert in 1948. Thromboelastography® (TEG®) and Thromboelastometry (ROTEM®) provide global information on the dynamics of clot development, stabilisation and dissolution that reflect in vivo haemostasis.

Thromboelastography ® (TEG ®) and Thromboelastometry (ROTEM ®) provide global information on the dynamics of clot development, stabilisation and dissolution that reflect in vivo haemostasis. ROTEM is a modern modification of the TEG technology originally described by Hertert in 1948 [1].

The graphs depict each deficit differently, so they can be corrected with replacement compounds such as cryoprecipitate, fresh frozen plasma (FFP), platelets and tranexamic acid. Literature and ongoing trials have shown by adding the TEG ® Hemostasis Analyzer System to your clinical practice and blood management program, you can help predict and manage coagulopathy , help assess the risk for re-operation , and realize cost savings through the reduction of unnecessary blood component transfusions . •TEG/ROTEM in coagulopathy, transfusion and mortality in trauma •55 studies (12,489 patients) •TEG/ROTEM were SN and SP for early detection/prediction of: •Hypocoagulability •Transfusion needs •Mortality •1 observational study suggested ROTEM-based algorithm reduces transfusion needs •No clear mortality reduction 2020-09-24 · ROTEM correlates with SLTs, assesses TIC/ATC, and predicts massive transfusion, need for transfusion, fibrinolysis, and coagulopathy-related mortality; Numerous studies verifying the above, looking at different aspects of ROTEM/TEG with different measurements and cut-offs which are the basis for management algorithms We have evaluated the TEG thromboelastograph and the ROTEM thromboelastometer, two point-of-care devices that measure blood coagulation.

ROTEM data had come up recently in Question 26 from the second paper of 2014. The best explanation of what the curves actually mean can be found at the Practical Haemostasis website. The LITFL TEG/ROTEM page also offers a good succinct explanation of what one can expect from normal and abnormal TEG tracings.
