Tranexamic acid in hip fracture patients: a protocol for a randomised, placebo controlled trial on the efficacy of tranexamic acid in reducing blood loss in hip fracture patients.

Introduction: There is a high incidence of blood transfusion following hip fractures in elderly patients. Tranexamic acid (TXA) has proven efficacy in decreasing blood loss in general trauma patients as well as patients undergoing elective orthopaedic surgery. A randomised controlled trial will measure the effect of TXA in a population of patients undergoing hip fracture surgery.
