Thrombelastography in the surgical patient


Bischof, D; Dalbert, S; Zollinger, A; Ganter, M T; Gantner, M T; Hofer, C K (2010). Thrombelastography in the surgical patient. Minerva Anestesiologica, 76(2):131-137.

Abstract

Coagulopathy in surgical patients is an important factor in triggering major perioperative complications, i.e., intra- or postoperative bleeding and thrombo-embolic events associated with an increased mortality and morbidity. Different methods exist to assess the coagulation status of patients before, during and after surgery. Routine coagulation tests have long been considered to be the clinical standard. However, these tests have considerable limitations. Information regarding the kinetics of clot formation, clot strength, interaction of the coagulation components, platelet function and fibrinolysis is not available. Moreover, there is an important delay in obtaining test results. In contrast, thrombelastography and thrombelastometry, which both measure the visco-elastic properties of whole blood, allow the dynamic assessment of a developing clot, from fibrin formation to clot strengthening and clot lysis. Both techniques are increasingly being used in daily clinical practice in order to detect perioperative coagulopathy and to guide predominantly pro-coagulant therapy in different settings. This article provides an overview of both techniques, thrombelastography (TEG) and thrombelastometry (ROTEM), and their field of perioperative application considering of recently published data.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
