TEG 6s

"This is the first study to systematically compare multiple next generation VET and platelet aggregation systems in both healthy and septic patients under controlled PTS transport conditions. It is hypothesized that PTS-induced acceleration may alter test results. Identifying a critical threshold could ensure safe, rapid blood transport without compromising diagnostic quality, potentially reducing personnel needs and expediting therapy initiation."

Viscoelastic testing (VET) has revolutionized modern coagulation management by offering rapid, real-time insights into the entire hemostatic process. By enabling precise, data-driven transfusion algorithms at the point of care, VET-guided strategies significantly improve patient blood management and clinical outcomes in high-stakes environments like trauma and cardiac surgery.

While new cartridge-based VHA devices simplify point-of-care testing, their clinical value is not yet fully established. Current research highlights a lack of interchangeability between devices and a shortage of data linking them to patient outcomes or comparing them to rapid conventional assays. Consequently, despite their technical promise, robust randomized clinical trials are still required to prove their utility in critical care settings.

"Both TEG 5000-FLEV and TEG 6s-CFF correlated moderately with Clauss fibrinogen but decreased in correlation in both hyperfibrinogenemia and hypofibrinogenemia. Thus, we caution relying on TEG 5000 or TEG 6s to be the only laboratory measurement to guide fibrinogen replacement when resuscitating trauma patients at risk for TIC and TEG 5000-FLEV for assessing fibrinogen in patients with ESRD at risk for thrombotic events."

Comparison between the Fibrinogen Clauss Assay and the TEG6S Citrated Functional Fibrinogen in Cardiac Surgery.

VHA-guided MHP showed marked variation with inconsistent transfusion thresholds [ROTEM® Sigma and TEG 6 s platforms within major haemorrhage protocols]. For similar clot kinetics, dosing of blood products and haemostatic agents differed, particularly PCC. Patients with the same coagulopathy may receive different treatment across hospitals. Centralised standardisation could improve PBM consistency.

"Upregulated thrombin generation parameters after PCC spiking were not displayed by CT, ACT [ROTEM® Delta, ClotPro®, TEG®6s, and Quantra®], or standard tests. Our results do not support treatment algorithms using prolonged CT or ACT as a trigger for administration of PCC to augment thrombin generation."

Agreement between the thromboelastography reaction time parameter using fresh and citrated whole blood during extracorporeal membrane oxygenation with Teg®5000 and Teg®6s.

"The present study revealed acceptable agreement between four different assays measuring functional fibrinogen, with current- and previous-generation ROTEM® machines (Sigma, Delta) performing similarly measuring functional fibrinogen via FIBTEM assay. This suggests that haemostatic resuscitation algorithms designed for the ROTEM® Delta can be applied to the ROTEM® Sigma to guide fibrinogen replacement."

Modern cartridge-based VET - specifically the TEG 6s, HemoSonics Quantra, and ROTEM sigma - offers superior portability and ease of use compared to traditional laboratory methods. Despite limited randomized evidence for these new-generation devices, VET-guided algorithms effectively reduce blood product usage without compromising patient outcomes. Future validation of clinical cut-offs will be key to optimizing transfusion management.
