ABSTRACT
PURPOSE:
Tranexamic acid (TXA) reduces need for transfusion in total joint arthroplasty, though findings in acetabular surgery are conflicting. We compared outcomes after acetabular fracture surgery with or without perioperative intravenous (IV) TXA administration.METHODS:
We performed a retrospective review of 305 patients with acetabular fractures that underwent open reduction and internal fixation (ORIF). Eighty-nine patients received TXA, and 216 did not. The primary outcome was rates of intraoperative and postoperative allogeneic blood transfusion.RESULTS:
Baseline demographics and characteristics were similar. Time from injury to surgery and estimated blood loss were comparable. Operative time (p < 0.01) and intraoperative IV fluids (p < 0.01) were greater in the non-TXA group. The proportion of patients who received blood transfusion and mean units transfused intraoperatively and postoperatively did not differ. Mean differences in preoperative and postoperative hemoglobin and hematocrit, hospital length of stay, and perioperative complications also did not differ. In a multivariable regression model, age 60-70 years, Charlson Comorbidity Index, Injury Severity Score, and fracture patterns likely to bleed were independently associated with intraoperative transfusion. Anterior surgical approaches and intraoperative transfusion requirement were independently associated with postoperative transfusion.CONCLUSION:
In this study, perioperative IV TXA did not decrease blood loss, need for transfusion, or improve in-hospital outcomes of acetabular fracture surgery. Age 60-70, CCI, ISS, and fracture patterns likely to bleed were independently associated with intraoperative transfusion. Anterior surgical approach and need for intraoperative transfusion were independently associated with postoperative transfusion. Further prospective trials are warranted to confirm these findings.Palavras-chave
