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. Sample cup is stationary 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 2014-09-27 An assessment of clinical interchangeability of TEG and RoTEM thromboelastographic variables in cardiac surgical patients.

These technologies provide a visual assessment of clot formation and subsequent lysis under low shear conditions (0.1/sec) similar to TEG and ROTEM for diagnosing trauma‑induced coagulopathy (disorder of the clotting system) in adult trauma patients with bleeding What is 'trauma-induced coagulopathy'? Trauma-induced coagulopathy (TIC) is a disorder of the blood clotting process that can occur soon after trauma injury that can lead to the patient bleeding to death. Thromboelastography (TEG) was first described by Hartert in 1948, and was designed to monitor viscoelastic clot strength in whole blood in real time. The current TEG method and Rotational Thromboelastometry (ROTEM) were subsequently developed from the original principles.

Equalis tillhandahåller program för extern kvalitetssäkring inom laboratoriemedicin, bild- och funktionsmedicin samt patientnära analyser. Verksamheten kompletteras med användarmöten, standardiserad terminologi och andra aktiviteter som syftar till harmonisering och förbättring av undersökningsresultat inom svensk sjukvård. Arbetet bedrivs vid kontoret i Uppsala med stöd av experter 2009-10-09 · We have evaluated the TEG ® thromboelastograph and the ROTEM ® thromboelastometer, two point‐of‐care devices that measure blood coagulation. During a one‐week period, seven consultant anaesthetists, one consultant haematologist, one associate specialist anaesthetist and two senior trainee anaesthetists were trained by the manufacturers and set up, calibrated and used both systems PubMed ROTEM/TEG’s several different channels assess platelet deficiency, fibrinogen deficiency, hyperfibrinolysis and coagulation deficits.

Thromboelastography (TEG) is a viscoelastic hemostatic assay that measures the global viscoelastic properties of whole blood clot formation under low shear stress TEG shows the interaction of platelets with the coagulation cascade (aggregation, clot strengthening, fibrin cross-linking and fibrinolysis) The TEG ® is produced by placing a 360 µl sample of whole blood into a pre-warmed (37°C) cup which is oscillated through an angle of 4°45′, rotating once every 10 s. This simulates a low shear environment resembling sluggish venous flow. A plastic pin is suspended in the blood sample by a torsion wire and monitored for motion. 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. The TEG ® incorporates kaolin and the ROTEM ® uses tissue factor in the EXTEM ® cuvette (extrinsic pathway allowing faster assessment of clot formation and fibrinolysis), and contact activator in the INTEM ® cuvette (intrinsic pathway). ROTEM is a modern modification of the TEG technology originally described by Hertert in 1948 [1]. These technologies provide a visual assessment of clot formation and subsequent lysis under low shear conditions (0.1/sec) similar to TEG and ROTEM for diagnosing trauma‑induced coagulopathy (disorder of the clotting system) in adult trauma patients with bleeding What is 'trauma-induced coagulopathy'?
