Major surgery can result in blood loss that can require a blood transfusion during and/or after surgery. Tranexamic acid (TXA) is a medication that was first introduced in the 1960's as a treatment for heavy menstrual bleeding. Over the past 20 years, it has been used and studied in patients undergoing open-heart surgery, liver transplantation, and urologic surgery. Investigators believe tranexamic acid may possibly decrease bleeding related to major burn surgery, resulting in reduced blood loss, lower blood transfusion rates, and possibly decreased hospital costs related to your stay.
