The use of viscoelastic hemostatic assays (VHAs) such as thromboelastography (TEG) and rotational thromboelastometry (ROTEM) are becoming increasingly common in the ED and trauma bay.

TEG and ROTEM can detect the hypercoagulable changes associated with pregnancy. Variability between study protocols and results suggests the need for future large prospective high-quality studies with standardized protocols to investigate the utility of TEG/ROTEM in assessing risk for thrombosis and hemorrhage as well as in guiding prophylaxis and treatment in obstetric patients.

Thromboelastography (TEG®) and rotational thromboelastometry (ROTEM®) have been utilized in several disease states with clinical varying success. OBJECTIVES: This review will summarize the literature and provide recommendations pertaining to major disease processes where VE may be beneficial, including trauma, anticoagulation reversal, liver disease, acute ischemic stroke, and … 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). Tromboelastometri och tromboelastografi (ROTEM/TEG) är patientnära koagulationsanalyser, som på bred front introduceras i syfte att styra behandling vid massiv blödning och koagulopati.Tromboelastografi (TEG) och tromboelastometri (ROTEM) för att mäta koagulationsförmåga är på snabb frammarsch. Metoderna kan göras bedside och ge svar inom 15 minuter.

f.venema@anest.umcg.n No se encontró evidencia sobre la exactitud de la TEG y hubo muy poca evidencia sobre la exactitud de la ROTEM. El valor de los cálculos de exactitud se debilita considerablemente por el número pequeño de estudios incluidos y las inquietudes acerca del riesgo de sesgo en relación con la prueba índice y el estándar de referencia. The TEG 5000 and TEG 6S Thromboelastograph Hemostasis Analyzers (Haemonetics) and the ROTEM (IL-Werfen) are global whole-blood analyzers that measure clotting time and the dynamics of clot formation and dissolution as effected by the kinetics of thrombin generation, platelet activation, fibrin generation, clot strength, clot stability, and inhibitory effects on any aspect. 133 These manual Se hela listan på wikem.org What is TEG?What is ROTEM?Why use it?What to give? when?All about the curves ..

18 It has been argued Thromboelastometry (TEM), previously named rotational thromboelastography (ROTEG) or rotational thromboelastometry (ROTEM), is an established viscoelastic method for hemostasis testing in whole blood. It is a modification of traditional thromboelastography (TEG). Editor’s Note: I was asked by a reader to do an article on thromboelastograms.

However, it has only been in the last few decades that assays have become accessible and viable as a point-of-care test. Following the observation that hemorrhagic shock is associated with an intrinsic coagulopathy, TEG has been used as a method of diagnosing specific coagulation 2010-09-15 The TEG vs the ROTEM thromboelastography ⁄ thromboelastometry systems G.

The graphs depict each deficit differently, so they can be corrected with replacement compounds such as 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 TEG ROTEM Two channels Four channels A pin connected with a torsion wire, is inserted into the sample. Sample cup oscillates The pin (sensor) is ﬁxed on the tip of a rotating shaft which is guided by a ball bearing system. The shaft rotates back and forth.

Clotting time (CT) or reaction time( R time) The time from the start of the curve until it reaches 1 mm wide This is the time taken to form fibrin. Interpretation of TEG Factsheet v1 Final March 2013.doc Page 1 of 2 Interpretation of TEG/ROTEM Factsheet 3 Area of Application The interpretation of the traces produced by the thromboelastography devices is vital for the management of coagulopathy and the corresponding appropriate use of blood components/therapies. TEG and ROTEM can detect the hypercoagulable changes associated with pregnancy.

The TEG device requires manual pipetting and can analyze two samples at a time. Fibrinolysis was measured with TEG® at 30 minutes after maximum amplitude (LY30) for RapidTEG® (CRT) and Kaolin (CK) assays and with ROTEM® at 30 minutes after clotting time (LI30) for INTEM and EXTEM assays. Device relationships to tPA were studied in linear or nonlinear models and measurement variances were studied with Bland-Altman analyses. The TEG and ROTEM portation, this was determined to be the sample ofalthough similar have minor differences in the mechanical aspects. This is represented in Table 1. Even though the parameters are identical there are differences in the diagnostic nomenclatures.

ROTEM and TEG provide essentially the same information on clot formation ki netics and strength. Because of differences in operating characteristics, the results are not interchangeable [2]. Furthermore, the two tests use di fferent nomenclature to describe the same parameters.

17 The devices share the same fundamental principles and many common features, and at a preliminary evaluation, appear to differ only in complexity and aspects of ease of use, in their purchase and running costs. 18 It has been argued Thromboelastometry (TEM), previously named rotational thromboelastography (ROTEG) or rotational thromboelastometry (ROTEM), is an established viscoelastic method for hemostasis testing in whole blood.
