TEG ger en övergripande bild av hur blodet koagulerar under fibrinpolymeriseringen och visar interaktionen mellan trombocyter, fibrin och fibrinolys. Trombelastogram kallas även för ROTEM (Rotation Thrombo Elasto Metry), NATEM eller TEG (Trombelastografi). 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 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 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.

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 2012-08-22 · TEG® MA and ROTEM MCF® were also linked to the need for blood transfusion and mortality. The few studies on TEG ® - or ROTEM ®-based transfusion algorithms suggested that while both tests can be used to construct transfusion guidelines, the blood products transfused differ according to the algorithm selected. Request PDF | TEG and ROTEM: technology and clinical applications | Initially described in 1948 by Hertert thromboelastography (TEG) provides a real-time assessment of viscoelastic clot strength •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 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. These two viscoelastic measures of whole blood provide essentially the same information on clot formation, kinetics, and strength, though they operate slightly differently.

Editor’s Note: I was asked by a reader to do an article on thromboelastograms.

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. TEG and ROTEM can detect the hypercoagulable changes associated with pregnancy.
