    Abstract:
    : Thrombelastography (TEG) parameters and prothrombin time (PT), activated partial thromboplastin time (APTT) are compared and analysed. According to change of TEG parameters and assessment of haemostatic state of each patient, we try to explore the feasibility of individualized anticoagulant therapies. 87 people with hip or knee diseases awaiting arthroplasty were recruited. Haemoglobin levels and TEG parameters including R, K, α-angle, maximum amplitude, coagulation index were assessed in perioperative period. PT and APTT were assessed preoperatively. For 65 patients with normal TEG parameters, PT and APTT, we use tranexamic acid (TXA) to reduce blood loss during operation. As hypercoagulability group, 12 patients awaiting unilateral total knee arthroplasty with hypercoagulable state assessed by TEG parameters or risks for venous thromboembolism received daily 10-mg rivaroxaban until 24 h preoperatively and did not receive TXA during operation. All patients received intravenous administration of argatroban after 8 h postoperatively until day 3 and oral administration of rivaroxaban (10 mg) subsequently to prevent deep vein thrombosis or/and pulmonary embolism until 35 days postoperatively. TEG parameters have significant relationships with fibrinogen, platelet and APTT. The number of patients with abnormal haemostatic state assessed by TEG parameters is higher than that assessed by PT, APTT. TEG show hypercoagulability develops throughout perioperative period. There was no significant difference in haemoglobin concentration between hypercoagulability group and normal group in patients receiving unilateral total knee arthroplasty. TEG have higher sensitivity of perioperative abnormal haemostatic state than PT, APTT in primary arthroplasty. For patients with hypercoagulability, individualized anticoagulant therapies such as preoperative administration of rivaroxaban and not using TXA in operation is safe and effective.
