The results of our study suggest that this increases the consistency and accuracy of VET results in clinical practice. 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. George, The surgical services in our hospital are requesting that we look into purchasing the Thromboelastograph (TEG) or Rotational Thromboelastometry System (ROTEM) in order to decrease blood utilization. TEG representatives tell surgical services that they can receive results with in 2 minutes of the blood being placed on the analyzer. •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 ROTEM data had come up recently in Question 26 from the second paper of 2014.

Compared with transfusion guided by any method, TEG or ROTEM seemed to reduce overall mortality (7.4% versus 3.9%; risk ratio (RR) 0.52, 95% CI 0.28 to 0.95; I 2 = 0%, 8 studies, 717 participants, low quality of evidence) but only eight trials provided data on mortality, and two were zero event trials. The TEG vs the ROTEM thromboelastography/thromboelastometry systems. Jackson GN (1), Ashpole KJ, Yentis SM. (1)Magill Department of Anaesthesia, Intensive Care & Pain Management, Chelsea and Westminster Hospital, London, UK. Erratum in Anaesthesia. 2009 Nov;64 (11):1272. One of the limitations of our study is that there are no standardized reference ranges for ROTEM and TEG. Nielsen 27 reported a 3-fold shorter CT compared with the TEG R time with a 7% higher Both devices hold typical traces of normal and abnormal coagulopathies and be used as comparisons to the current trace. A normal ROTEM trace: A normal TEG trace The following measurements are shown: R (time of formation of the fibrin strand polymers); K (speed at which the clot forms); (the slope drawn from R to K) and MA (strength of 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).

ROTEM or TEG) to guide trauma resuscitations. For the purpose of this post we will focus on ROTEM as this is predominantly used in Canada. I have no experience with the ROTEM, though many Fritsma Factor participants use them.

The predictive measurements of clot lysis (CL) (ROTEM LI30 and TEG CL30) were also compared in this study by using one cut point and logistic regression rather than the ROC curves used for MCF and MA. This was due to the skewed non-normal distribution of the LI30 and CL30 measurements. 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. 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.

122 Analysis 4.1. Comparison 4 TEG or ROTEM in combination with SLT or other devices versus clinical judgement or usual The ROTEM system generated significantly (P<0.05) smaller reaction time (mean +/- SD, 459 +/- 39 versus 788 +/- 94 s) and greater angle (60.1 +/- 5.3 versus 46.4 +/- 4.6 degrees), maximum amplitude 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. Results: 33 patients (74 ROTEM, 74 TEG) were included; 79% were male, mean Injury Severity Score was 23.5 ± 14, admission international normalized ratio was 1.33 ± 0.4, and 63.4% received blood transfusions. Overall, parameter agreement fell outside acceptable limits, with weak or no association. TEG® VERSUS ROTEM® Comparison.

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). 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. Partager : Click to share on Twitter (Opens in new window) include thromboelastography (TEG®) and the Sonoclot® analyser. These have slight differences compared to ROTEM® in terms of whether it is the pin or the cup that oscillates and the direction in which the oscillation occurs.

TEG had better sensitivity to low platelet counts (TEG 100%, ROTEM 0%). The average time to a clinical decision was significantly faster with ROTEM (Intem- 13 minutes) as compared to TEG (26 minutes, p<0.0001).

Thromboelastography (TEG) e tromboelastometria (Rotem) sono sempre più utilizzati per guidare la strategia di trasfusione ma i loro ruoli rimangono in discussione. OBIETTIVI: valutare sistematicamente i benefici ei rischi di una strategia guidata trasfusione TEG o ROTEM in studi clinici randomizzati condotti su pazienti con emorragia severa. Comparison 1 TEG or ROTEM versus any comparison, Outcome 10 Patients receiving platelets; grouped by coagulopathy or severe postoperative bleeding 8 Jun 2015 and switch the focus in particular to a comparison and differentiation between the two prevalent systems, the TEG and the emerging ROTEM. In the TEG analyzer, the cup in which the blood is placed oscillates; in the ROTEM analyzer, the pin oscillates while the cup remains fixed.

Total Testing Time for Sonoclot: 18 mins for Thromboelastography TEG: 112 mins and it showed Factor deficiency. Sample II: Sonoclot showed that the patient is having Platelet Dysfunction.

In the TEG, the cup oscillates around the metal pin, whereas the pin moves around the cup in the RoTEM, conferring more stability against vibrations. Analysis 3.4.

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. 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 Both Thromboelastography (TEG) and Rotational Thromboelastometry (ROTEM) have been increasingly used to diagnose fibrinogen deficiency and guide fibrinogen transfusion in trauma and surgical bleeding patients. Few previous studies have compared TEG and ROTEM in patients and only one study compared TEG 6s and ROTEM Sigma measurements in blood samples from healthy volunteers.
