RT Journal A1 Inaba K T1 Antifibrinolytics in trauma patients: Does it matter?: comment on “military application of tranexamic acid in trauma emergency resuscitation (matters) study” JF Archives of Surgery JO Archives of Surgery YR 2012 FD February 1 VO 147 IS 2 SP 119 OP 119 DO 10.1001/archsurg.2011.286 UL http://dx.doi.org/10.1001/archsurg.2011.286 AB Our understanding of the coagulation system defects associated with injury continues to evolve. Hyperfibrinolysis has been identified as one of these coagulation abnormalities. Recently, the therapeutic impact of the antifibrinolytic tranexamic acid was examined in the CRASH-2 study.1 Despite a subtle but significant outcome benefit, direct application of these results to clinical practice was made challenging by several factors, including the inclusion criteria that effectively diluted out those patients who were actually bleeding. These results became even more difficult to interpret when an analysis of the time from injury to treatment demonstrated an increase in the risk of death due to bleeding2 if the antifibrinolytic was administered beyond 3 hours.
