Abstract
BACKGROUND: Allogeneic blood transfusion has been linked with an increase in the risk of surgical site infections (SSIs) through the mechanism of immunomodulation. However, no studies to date have investigated the direct relationship between blood conserving strategies including antifibrinolytics and wound complications after total hip arthroplasties (THA). METHODS: A systematic review and meta-analysis of published randomised controlled trials (RCTs) to investigate the effect of tranexamic acid (TXA) on wound complications after THAs has been conducted. RESULTS: We identified 25 clinical trials which were suitable for detailed data extraction. There were no trials which utilised TXA in revision THA. All studies reported on wound complications including a total of 1608 patients. Using TXA led to a 2% reduction in the risk of developing wound complications compared to the control group with no significant statistical heterogeneity among the study groups (Risk Difference -0.02, 95%, confidence interval CI -0.04 to -0.00, P = 0.01, Heterogeneity I2 = 0%). However, there was no significant difference in clinical outcomes in terms of antibiotic treatment or surgical intervention among the study groups. TXA also reduced intraoperative, postoperative and total blood loss and led to a significant reduction in the proportion of patients requiring allogeneic blood transfusion with no significant differences in deep venous thrombosis, pulmonary embolisms, or other complications between the study groups. CONCLUSION: TXA reduced blood loss and transfusion rates after primary THA surgery. It also reduced wound complication rates but the clinical significance of this needs further investigation through well designed and adequately powered RCTs.
