Complications of Preinjury Warfarin Use in the Trauma Patient

Abstract

We conclude that the preinjury use of warfarin does not place the trauma patient at increased risk for fatal hemorrhagic complications in the absence of head trauma. Furthermore, the presence of a head trauma alone is not predictive of mortality. However, the presence of intracranial injury is strongly associated with a mortality rate that is significantly higher than patients with head trauma who are not taking warfarin. LOC is also associated with mortality, but the absence of loss of consciousness does not reliably indicate the absence of intracranial injury or risk of death.
