Purpose
Total hip arthroplasty (THA) is an intervention with significant inflammatory response. The impact of additional doses of tranexamic acid (TXA) on inflammatory response, trauma and nutrition parameters, and coagulation and fibrinolysis changes has rarely been reported.
Methods
A prospective double-blind randomized trial was performed on elective primary THA. Ninety-nine adult patients were recruited consecutively from 2019 to 2020. They were randomized to receive single-dose of TXA before incision, another dose of TXA at three hours post-operatively, or another two doses of TXA at three and six hours post-operatively. The primary outcomes included changes in white blood cell (WBC) counts, creatine kinase (CK), haemoglobin(Hb), and albumin(Alb); the secondary outcomes included coagulation and fibrinolysis parameters.
Results
Compared with single-dose TXA, patients received three dose TXA had significantly reduced WBC counts and fibrinogen/fibrin degradation product (FDP) levels, increased albumin and fibrinogen levels, and prolonged PT on post-operative day (POD) three. Though patients received three dose TXA had a tendency that increased Hb, decreased CK, reduced D-D, and prolonged APTT on POD3, it is not statistically significant. And the other measured outcomes on POD1 and POD2W shared a similar statistical result, except PT. The PT is significantly prolonged on POD2W in three dose group compared with single dose.
Conclusion
Three-dose TXA contribute to attenuate early post-operative systemic inflammatory response and nutritional loss, increase fibrinogen, reduce FDP levels, and prolong PT in THA patients within an ERAS pathway, which may associate with reduced early post-operative haemorrhagic tendency, thrombosis risks, and hypercoagulability.
