Intravenous tranexamic acid is associated with safe reduced blood loss and transfusion rate in one-stage exchange for infected hip arthroplasty

Objectives This study aims to investigate if the use of intravenous (IV) tranexamic acid (TXA) during one-stage exchange for periprosthetic joint infection (PJI) of the hip that necessitates an extensive debridement is associated with decreased blood loss, if the rate of blood transfusion that may lead to side effects can be lowered with IV TXA, and if there is any difference regarding the occurrence of postoperative venous thromboembolism (VTE). Patients and methods We retrospectively reviewed patients who underwent one-stage exchange for PJI of the hip with perioperative IV administration of TXA (n=163; 90 males, 73 females; mean age 68±10.3; range, 25 to 90 years) between January 2015 and December 2016 and compared them to another group (n=190; 106 males, 84 females; mean age 71±10.1; range, 39 to 92 years) who underwent one-stage exchange for PJI of the hip without perioperative IV administration of TXA between January 2006 and December 2012. Blood loss, transfusion rates, amount of transfused blood, and occurrence of VTE complications were observed. Results Mean blood loss of the TXA group was significantly lower than that of the non-TXA group (2.4 L and 4.5 L, respectively; p
