Comparison of Sonoclot with Thromboelastography TEG in Liver Transplant Sample I: Sonoclot showed that the patient is having Platelet Dysfunction. Total Testing Time for Sonoclot: 18 mins for Thromboelastography TEG: 112 mins and it showed Factor deficiency

Two of the most commonly used viscoelastic hemostatic assays, thromboelastometry (ROTEM) and thrombelastography (TEG), have proven to decrease allogenic blood transfusions with cost reduction and possibly decrease mortality and morbidity in cardiac, trauma, and other bleeding patients. This article compares the two devices to provide guidance on the selection and use of these monitoring systems.

The two clinical studies were in liver transplantation and in cardiac surgery, another was an experiment using commercially available plasma and the last was a head-to-head comparison of the technical aspects, ease of use and costs [ 7 , 10 – 12 ]. This head-to-head comparison of TEG ® and ROTEM ® in identification of hyperfibrinolysis in 37 adult LT patients demonstrated that ROTEM ® assays were more sensitive than k-TEG ®. Furthermore, FIBTEM ® was more sensitive than EXTEM ® in identifying hyperfibrinolysis. Strong to very strong correlations were observed between corresponding TEG 6s and ROTEM Sigma parameters. However, absolute values showed significant differences for most of the measurements. Comparison between the new fully automated viscoelastic coagulation analysers TEG 6s and ROTEM Sigma in trauma patients: A prospective observational study This head-to-head comparison of TEG ® and ROTEM ® in identification of hyperfibrinolysis in 37 adult LT patients demonstrated that ROTEM ® assays were more sensitive than k-TEG ®. Furthermore, FIBTEM ® was more sensitive than EXTEM ® in identifying hyperfibrinolysis.

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. ROTEM, however, is somewhat different to TEG; the machine offers four …

It is a modification of traditional thromboelastography (TEG). Le TEG comme le ROTEM font parties des méthodes qui, loin de révolutionner la médecine, permettent de la rendre plus efficiente et peut être plus intéressante aussi pour nous.

TEG 6s functional fibrinogen level was compared with plasma fibrinogen concentration, measured using the Clauss method. Correlations were classified as weak (Spearman correlation coefficient 0.20 to 0.39), moderate (0.40 to 0.59), strong (0.60 to 0.79) or very strong (≥0.80).

The RoTEM instrument analyses each parameter in a separate channel while in the TEG, all the parameters are analyzed simultaneously. Analysis 3.4.

ROTEM, however, is somewhat different to TEG; the machine offers four … Mechanistically, TEG and ROTEM both rely on measurements of the torsional force exerted on a pin suspended within a disposable plastic cup containing a sample of a patient’s whole blood. While TEG operates by spinning the cup itself, ROTEM devices spin the pin while holding the cup stable. 4 The devices generate a graph of the measured elasticity of the blood, expressed in millimeters (mm In both methods, whole blood is inserted into a cup, which must be pre‐warmed to 37°C.

Comparison 4, assessing the effect of TEG or ROTEM in combination with standard laboratory tests or other devices (Summaryoffindings4),thusincludesboththepotentialeffectof adding a platelet function analysis and adding TEG or ROTEM tostandardlaboratorytests.Table10illustratesthemultiplicityof 2006-08-01 · Rotem software allows Rotem CT and MCF to be described as R time and MA. For ease of comparison between TEG and Rotem, Rotem CT and MCF will be described as Rotem R time and Rotem MA, respectively. TEG parameters are influenced by the presence of heparin/heparinoid substances. In fact the main difference between TEG and ROTEM is the bit which rotates (TEG rotates the cup, and ROTEM rotates the pin).

However, they provide similar information on clot formation.

The ROTEM Delta and cartridge‐based Sigma system (Instrumentation Laboratories, Bedford, MA), the ClotPro device (Enicor, Munich, Germany), and the TEG 5000 (Haemonetics, Braintree, MA) use a traditional viscoelastic method, while the newer cartridge‐based TEG 6S system, the Sonoclot device (Sienco Inc., Morrison, CO), and the Quantra system (HemoSonics, Charlottesville, VA) use a

8 Mar 2017 Head-to-head comparisons between ROTEM and TEG were also excluded, if they were assessed in absence of an established hemostasis 

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. This head-to-head comparison of TEG ® and ROTEM ® in identification of hyperfibrinolysis in 37 adult LT patients demonstrated that ROTEM ® assays were more sensitive than k-TEG ®. Furthermore, FIBTEM ® was more sensitive than EXTEM ® in identifying hyperfibrinolysis.

2020-09-24 2019-03-06 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). TEM investigates the interaction of coagulation factors, their inhibitors, anticoagulant drugs, blood cells, specifically platelets 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. •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 Comparison of Thromboelastometry (ROTEM 2015-02-16 Travis Morrison-McKell MD, B.
