RESUMEN
Objective: To evaluate the efficacy of different doses of tranexamic acid plus traditional Chinese medicine (TCM) in hip arthroplasty in diabetic patients and the effect on intraoperative hemorrhage and postoperative drainage. Methods: One hundred patients admitted to our hospital from January 2019 to September 2021 were randomly divided into group B (n = 50) and group A (n = 50), and tranexamic acid was injected intravenously at a dose of 10 mg/kg and 20 mg/kg 30 min before skin incision, and then tranexamic acid 1.0 g was injected into the joint cavity through the drainage after incision closure, followed by 3 h of drainage clamping. The amount of blood loss, coagulation index, postoperative drainage, and incidence of venous thromboembolism (VTE) were compared between the groups. Results: Group A had significantly less total blood loss, dominant blood loss, and hidden blood loss than group B (P < 0.05). No significant difference in postoperative coagulation indexes and postoperative drainage flow was found between the two groups (P > 0.05). Serological examination results demonstrated no statistical difference in D-dimer (D-D) levels between the two groups. The absence of VTE in both groups was determined by imaging. Conclusion: Tranexamic acid is effective in reducing intraoperative hemorrhage in diabetic patients undergoing hip arthroplasty. The dose of 20 mg/kg outperforms 10 mg/kg in terms of clinical efficacy with a favorable safety profile, which can be applied according to the patient's actual condition.
