Description
Background: Coagulopathic trauma patients are at a three-fold higher risk of death compared to noncoagulopathic patients. However, identification and targeted treatment of coagulopathy is still being researched. Thromboelastography (TEG) may allow us to not only identify these patients, but also provide optimal transfusion to reverse coagulopathy. Methods: This was a secondary analysis of a multicenter retrospective review, which included adult patients receiving massive transfusion protocol. A numerical “TEG score” was calculated for each patient based on abnormalities in TEG alpha angle (<65 >degrees), clot time (>8.9 min), and clot strength (<55 >mm). Each abnormal value was assigned a point value of 1, with the overall TEG score range 0-3. Multiple regression was used to control confounding variables while evaluating the association between abnormal TEG values and key outcome variables, including patient mortality and blood product transfusion. Results: Abnormal TEG angle was significantly predictive of 24-hour platelet (p
