The efficacy of oral versus intravenous tranexamic acid in reducing blood loss after primary total knee and hip arthroplasty-A meta-analysis
Keywords:THA, TKA, Medline, Embase, PE
Introduction: Total hip and knee arthroplasty is known as one of the most successful surgeries for relieving pain and improving physical function. However, perioperative blood loss is one of the major complications following total hip arthroplasty (THA) and total knee arthroplasty (TKA).Materials and Methods: We systematically searched randomized controlled trials (RCTs) from Medline, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and Google scholar. Eligibility criteria: Patients: adult patients with end-stage joint osteoarthritis, rheumatoid arthritis, and osteonecrosis of the femoral head, who prepared for JTA; Interventions: The experiential group received the intravenous form of TXA; Comparisons: An oral form of TXA; Outcomes: Total blood loss, hemoglobin reduction, transfusion requirements, duration of hospitalization, and thrombotic complications including deep vein thrombosis (DVT) and pulmonary embolism (PE); Study design: Randomized control trials (RCTs) and non-RCT. Meta-analysis results were collected and analyzed by the software STATA 11.0. After testing for heterogeneity between studies, data were aggregated for random-effects models when necessary.Results: Four RCTs and two non-RCTs were included in the meta-analysis. The present meta-analysis revealed that there were no significant differences regarding total blood loss (WMD=_25.013, 95% CI: _51.002 to 0.977, P=.059), postoperative hemoglobin decline (WMD=_0.090, 95% CI: _0.205 to 0.024, P=.122), or transfusion rate (RD=_0.039, 95% CI: _0.080 to 0.002, P=.062) between the 2 groups.Conclusion: Oral TXA shows comparable Efficacy to that of the intravenous forms after total knee and hip arthroplasty. Due to the limited quality of evidence currently available, higher quality RCTs is necessary.
