These two viscoelastic measures of whole blood provide essentially the same information on clot formation, kinetics, and strength, though they operate slightly differently.

29 Apr 2020 Therefore, viscoelastic coagulation tests including ROTEM & TEG would be useful to guide patient blood management strategy during liver 1 May 2018 ROTEM provides a rapid assessment of clot development from secondary hemostasis to clot lysis by evaluating clot formation, clot firmness, and The measures commonly used in the evaluation of patients with bleeding disorders are: Coagulation time: R on TEG and CT on ROTEM; Clot Formation time: K on 1 May 2016 TEG used kaolin as coagulation initiator and ROTEM used tissue factor Positive tests correlate well with bleeding and may guide the clinical TIC can exacerbate severe bleeding in trauma patients and there is a need for rapid site-of-care management to guide transfusion and improve outcomes. The 16 Feb 2015 In some centres TEG and ROTEM are used routinely to test patients' blood, but We recognise that the reference standards of PT and INR are Additional criteria had to be fulfilled for inclusion of correlation studies: ROTEM and TEG data in combination with at least one established parameter of hemostasis 1 Dec 2020 The goal of this practice management guideline was to evaluate the role RESULTS: Using TEG/ROTEM-guided blood transfusions in acutely 12 Feb 2019 The use of TEG to guide blood product administration substantially affected Several reports suggest that TEG and ROTEM are effective in as well as to guide judicious resuscitation with transfusion of blood products. and platelet count.2 However, because ROTEM and TEG tests use whole blood 17 Jun 2019 This was a study of using TEG to guide blood product administration prior to a variety of ROTEM and TEG are very similar viscoelastic tests. 8 Mar 2017 Additional criteria had to be fulfilled for inclusion of correlation studies: ROTEM and TEG data in combination with at least one established 6 Mar 2019 Rotational thromboelastometry is recommended to guide haemostatic Although parameters of TEG and ROTEM are not interchangeable of a ROTEM (C) alter testing results (O)?.

The goal of this practice management guideline was to evaluate the role of the viscoelasticity tests, which are thromboelastography (TEG) and rotational thromboelastometry (ROTEM), in the management of acutely bleeding trauma, surgical, and critically ill patients. ROTEM® Basic Interpretation Guide Parameter: Clotting Time CT - Clotting Time (seconds) – The time from the start of the test until first significant levels of a clot are detected. This measurement is initiated by adding a clot activator until an amplitude of 2 mm is reached. Clinical situations in which ROTEM/TEG might be useful.
TEG and ROTEM: The Basics TEG and ROTEM are close cousins that assess in real time the entire coagulation process, including fibrin formation and clot rate, strength, stability, and lysis.
tion is made. A typical trace for TEG and ROTEM is shown in Fig 2 and a Sonoclot trace is illustrated in Fig 3. Although TEG and ROTEM traces look identical, the parameters are not directly interchangeable and should not be regarded as equivalent (Coakley et al, 2006; Venema et al, 2010; Hagemo et al, 2015; Rizoli et al, 2016).
