TEG/ROTEM – traumarummet


Faktor XIII, fibrinogen och Application Regionala FoU

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 Se hela listan på practical-haemostasis.com 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. ROTEM is a modern modification of the TEG technology originally described by Hertert in 1948 [1].

In order to perform a TEG, a citrated-sample of whole blood is placed into a heated sample cup with calcium chloride (to overcome the effects of the citrate), kaolin (a negatively charged molecule known to initiate the intrinsic pathway 10), and phospholipids (required for optimal functioning of the extrinsic pathway 11) (Figure 2). Background Point of care viscoelastic measures with thromboelastography (TEG; Haemonetics Corporation, Switzerland) and thromboelastometry (ROTEM, Tem Innovations GmbH, Germany) now supersede laboratory assays in the perioperative assessment and management of coagulation. To the best of our knowledge, this sophisticated coagulation assessment has not been performed to characterise thrombotic Save my name, email, and website in this browser for the next time I comment.

I samtliga randomiserade studier sågs att mängden transfusioner var minskad till både antal och volym i den grupp där transfusioner styrdes av TEG-/ROTEM-baserad algoritm. Studierna var utförda vid hjärt- och 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 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. 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.

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).

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. 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.
