p Value is massive transfusion vs non-massive transfusion.
ABC, assessment of blood consumption score; ACT, thrombelastography activated clotting time; Ht, high dose tissue plasminogen activator thrombelastography; INR, internal normalized ratio; Lt, low dose tissue plasminogen activator thrombelastography; LY30, percent clot lysis 30 minutes after reaching maximum amplitude; MA, maximum amplitude; N, native thrombelastography; R, rapid thrombelastography; TASH, trauma associated severe hemorrhage.
