OBJECTIVE: Developing pragmatic data-driven algorithms for management of trauma induced coagulopathy (TIC) during trauma hemorrhage for viscoelastic hemostatic assays (VHAs). BACKGROUND: Admission data from conventional coagulation tests (CCT), rotational thrombelastometry (ROTEM) and thrombelastography (TEG) were collected prospectively at 6 European trauma centers during 2008 to 2013. METHODS: To identify significant VHA parameters capable of detecting TIC (defined as INR > 1...

BACKGROUND: Despite its central role in early trauma coagulopathy, abnormal fibrinolysis continues to be poorly understood. Excessive fibrinolysis is a known contributor to mortality. Recent studies with thromboelastography (TEG) suggest decreased fibrinolysis (or shutdown) may be just as harmful. Considering the broad use of 2 different viscoelastic assays, which are not interchangeable, we proposed for the first time to define and characterize fibrinolysis shutdown using rotational thromboelastometry (ROTEM)...

Introduction Evidence supporting the use of Thromboelastography (TEG®) and rotational thromboelastometric (ROTEM®) in the trauma setting remains limited. We present the results of a practical evaluation of the potential interest of ROTEM® in the diagnosis of acute coagulopathy and the need for emergent blood product transfusion in the general trauma population of a non-trauma Belgian emergency department. Methods Extracting a convenience cohort from the initial prospective TICCS study, we performed a retrospective analysis to test the following hypothesis: ROTEM® might be helpful to discriminate trauma patients with or without acute coagulopathy...

INTRODUCTION: In the last few years, viscoelastic point-of-care (POC) coagulation devices such as thromboelastography (TEG), rotational thromboelastometry (ROTEM), and Sonoclot (SON) analyzer have been increasingly used in major surgeries for timely assessment and management of coagulopathies. The aim of the present study was to evaluate coagulation profile of cyanotic cardiac patients with TEG, ROTEM, and SON analyzer. In addition, we assessed the correlation of standard laboratory coagulation tests and postoperative chest drain output (CDO) with the parameters of POC testing devices...

Bleeding complications after cardiac surgery are common and are associated with increased morbidity and mortality. Their etiology is multifactorial, and treatment decisions are time sensitive. Point-of-care (POC) testing has an advantage over standard laboratory tests for faster turn-around times, and timely decision on coagulation intervention(s). The most common POC coagulation testing is the activated clotting time (ACT), used to monitor heparin therapy while on cardiopulmonary bypass. Viscoelastic coagulation tests including thromboelastometry (ROTEM) and thromboelastography (TEG) have been recommended for the treatment of postoperative bleeding after cardiac surgery because the ROTEM/TEG-guided treatment algorithms reduced the use of blood products...

Viscoelastic hemostatic assays (VHAs), mainly thromboelastography (TEG) and the rotational thromboelastometry (ROTEM), provide global information on clot formation and dissolution at patient bedside, allowing fast identification of coagulation disorders. In trauma patients, VHAs are able to predict massive transfusion and mortality. These devices might also be used for applying targeted administration of procoagulant factors (e.g. fibrinogen concentrate) as an alternative to or in addition to using predefined fixed ratios of red blood cells: platelets: fresh frozen plasma/cryoprecipitate...

BACKGROUND: There is growing interest in viscoelastic hemostatic assays rotational thromboelastometry (ROTEM) and thromboelastography (TEG) for trauma. Despite shared features, it is unknown whether their results are interchangeable and whether one is clinically superior in predicting mortality, blood transfusion, and diagnosing early trauma coagulopathy. METHODS: We conducted a prospective observational study comparing equivalent ROTEM and TEG parameters. Severely injured patients expected to receive massive transfusion were included...

Fibrinogen has a central role in coagulation. Following trauma and perioperatively, low fibrinogen levels have been found to be risk factors for exaggerated bleeding, transfusion needs, and adverse outcome. Conversely, treatment with exogenous fibrinogen in critically bleeding patients with low fibrinogen levels has been shown to decrease transfusion needs. Because following trauma and in many perioperative situations fibrinogen is the first coagulation "element" to become critically low, it appears reasonable to target fibrinogen in clinical coagulation algorithms aiming at early specific and goal-directed treatment...

PURPOSE: Early detection and management of trauma haemorrhage and coagulopathy have been associated with improved outcomes. We assessed infrastructure, logistics and management practice of trauma-associated haemorrhage and coagulopathy across German trauma centres. METHODS: A web-based survey of 20 questions was developed using the open source survey application LimeSurvey® . It was disseminated among surgeons and anaesthetists in Germany. RESULTS: 145 Questionnaires were returned of which 106 were completed and analysed...

The viscoelastic properties of blood clot have been studied most commonly using thrombelastography (TEG) and thromboelastometry (ROTEM). ROTEM-based bleeding treatment algorithms recommend administering platelets to patients with low EXTEM clot strength (e.g., clot amplitude at 10 minutes [A10] <40 mm) once clot strength of the ROTEM® fibrin-based test (FIBTEM) is corrected. Algorithms based on TEG typically use a low value of maximum amplitude (e.g., <50 mm) as a trigger for administering platelets...

BACKGROUND: Fibrinogen-based clot firmness is reported as the maximum amplitude (MA) when using the citrated functional fibrinogen (CFF) assay in thrombelastography (TEG), and as the maximum clot firmness (MCF) together with several clot amplitude parameters when using the FIBTEM assay in thromboelastometry (ROTEM). Concern is currently being raised that these two tests have different platelet inhibiting performance and consequently provide different values. This is relevant for the clinical setting of fibrinogen replacement...

Viscoelastic tests such as thrombelastography (TEG, Haemoscope Inc., Niles, IL) and thromboelastometry (ROTEM, Tem International GmbH, Munich, Germany), performed in whole blood, are increasingly used at the point-of-care to characterize coagulopathic states and guide hemostatic therapy. An algorithm, based on a mono-analysis (kaolin-activated assay) approach, was proposed in the TEG patent (issued in 2004) where the α-angle and the maximum amplitude parameters are used to guide fibrinogen supplementation and platelet administration, respectively...

Although there is increasing interest in the use of a viscoelastic test procedure (ROTEM/TEG) for diagnostics and therapy guidance of severely injured and bleeding patients, currently no uniformly accepted guidelines exist for how this technology should be integrated into clinical treatment. In September 2014 an international multidisciplinary group of opinion leaders in the field of trauma-induced coagulopathy and other disciplines involved in the treatment of severely injured patients were assembled for a 2-day consensus conference in Philadelphia (USA)...

PURPOSE: Viscoelastic hemostatic assays are emerging as the standard-of-care in the early detection of post-injury coagulopathy. TEG and ROTEM are most commonly used. Although similar in technique, each uses different reagents, which may affect their sensitivity to detect fibrinolysis. Therefore, the purpose of this study is to determine the ability of each device to detect fibrinolysis. METHODS: TEG (Rapid, Kaolin, Functional Fibrinogen) and ROTEM (EXTEM, INTEM, FIBTEM) were run simultaneously on normal blood as well as blood containing tPA from healthy volunteers (n = 10)...

BACKGROUND: Viscoelastic point-of-care tests such as thromboelastography (TEG) and rotational thromboelastometry (ROTEM) are increasingly used to guide hemostatic therapy after cardiac surgery. The aim of this study was to assess their clinical utility during cardiopulmonary bypass to predict postbypass coagulation status and to guide therapy. METHODS: In this prospective study, TEG and ROTEM tests were performed in 52 adult patients undergoing elective cardiac surgery at two time points: near the end of cardiopulmonary bypass and after heparin reversal with protamine...
