Question 24#

What are the uses of thromboelastography (TEG)?

A. Predicting need for lifesaving interventions after arrival for trauma
B. Predicting 24-hour and 30-day mortality following trauma
C. Predicting early transfusion of RBC, plasma, platelets, and cryoprecipitate
D. All of the above

Correct Answer is D

Comment:

Thromboelastography (TEG) is the only test measuring all dynamic steps of clot formation until eventual clot lysis or retraction. TEG has also been shown to identify, patients who are likely to develop thromboembolic complications postinjury and postoperatively. Recent trauma data have shown TEG to be useful in predicting early transfusion of RBCs, plasma, platelets, and cryoprecipitate. TEG can also predict the need for lifesaving interventions shortly after arrival and to predict 24-hour and 30-day mortality. Lastly, TEG can be useful to guide administration of tranexamic acid to injured patients with hyperfibrinolysis.
