RESUMO
Objective Coagulation disorder is an independent risk factor of death in trauma patients. This study aimed to investigate the prognostic value of thromboelastography (TEG) for patients with trauma-induced coagulopathy.Methods This retrospective study included 124 cases of trauma-induced coagulopathy treated in our Department of Critical Care Medicine from September 2015 to July 2018. We collected the clinical data and laboratory Results of the patients within 2 hours after admission, divided the patients into a survival group (n=108) and death group (n=16) according to their 90-day prognosis after trauma, and compared the TEG parameters between the two groups. Using logistic regression analysis and ROC curves, we identified the optimal prognostic factors and compared the platelet (PLT) count and mortality rate among those with different cut-off values.Results In comparison with the survival group, the death group showed a significant increase in the clot formation time (CFT) (3.2 \[2.2-4.8\] vs 5.2 \[5.0-9.8\] min, P45.65 mm (86 \[46-114\] vs 116 \[84-171\]×109/L, P<0.05), and mortality was remarkably higher in the former than in the latter group (31.8% vs 1.2%, P<0.05).Conclusion Among the TEG parameters, MA / maximal clot strength is a valuable indicator for the prognosis of trauma-induced coagulopathy, and MA<45.65 mm indicates early PLT dysfunction and poor prognosis.
