ABSTRACT
Objective@#To assess the diagnosis of thrombelastography (TEG) for trauma-induced coagulopathy (TIC) and explore whether TEG could guide transfusion for TIC patients.@*Methods@#We retrospectively analyzed all trauma patients who underwent the TEG and conventional coagulation tests (CCTs) admission in the emergency intensive care unit from February to December 2018. The definition of TIC is prothrombin time (PT) 18 s, international normalized ratio (INR) 1.5, activated partial thromboplastin time (APTT) 60 s or platelet count (PLT) 100×109/L. The diagnostic value of TEG for TIC was evaluated by receiver operating characteristic curve, area under the curve (AUC), sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), and the transfusion guidance of TEG for TIC patients was assessed by multivariate regression analyses.@*Results@#A total of 242 patients were included, including 62 patients in the TIC group and 180 patients in the non-TIC group. The differences in TEG between the two groups were statistically significant. The AUCs of TIC assessed by maximum amplitude (MA) and coagulation index (CI) were the largest, 0.779 and 0.786 respectively, and the sensitivity were greater than 80% and NPV were greater than 90%. The sensitivity, PPV and NPV of reaction time (R) were minimal. After confounders were controlled, all TEG values were correlated with blood volumes within the first 24 h and massive transfusion, of which R had the highest odds ratio and regression coefficient.@*Conclusions@#MA and CI have the highest diagnostic value, while R has little diagnostic value but a relatively large blood therapeutic significance of TIC. MA < 52.9 mm or CI < -1.0 can be used as a threshold for identifying TIC. The diagnosis of TIC and the guidance transfusion for TIC patients by TEG is beneficial.
