Email this article Applications of Thromboelastography (TEG) in Microsurgery: A Systemic Review and Meta-Analysis
Abstract
Viscoelastic testing including thromboelastography (TEG) and rotational thromboelastometry (ROTEM) has gained increasing popularity across many medical fields in recent years. As TEG/ROTEM testing usesawhole blood sample and evaluates interactions between cellular components i.e., platelets, red blood cells and the clotting factors, these evaluations are uniquely capable of assessing coagulation in an in-vitro environment, resembling native conditionsunlike those of conventual clotting tests (CCTs). While viscoelastic based protocols and applications are more commonplace in hepatic and cardiac surgery and trauma scenarios, results have attracted the attention of additional disciplines including microsurgery. TEG/ROTEM tests, with their ability to assess forreal-time risk of excessive bleeding or thrombosis, may be useful in the monitoring of microsurgery patients who may be at an increased risk for flap failure. The following review of TEG/ROTEM testing focuses on the most common applications of these coagulation tests and the evidence that does or does not support such uses. A systematic review and meta-analysis of the current application of TEG/ROTEM in microsurgery is reported along with an emphasis on the future that it might hold for the field.
