Abstract:
Objective To explore the perioperative efficiency and safety of different regimen of tranexamic acid (TXA) in total knee arthroplasty (TKA).Methods From February 2013 to May 2013,150 female patients with knee osteoarthritis underwent unilateral TKA were randomly divided into three groups,50 cases in each group.Patients received 10 mg/kg TXA by fast intravenous infusion before closing the wound in first group (single dose group),patients in second group received two doses of 10 mg/kg TXA before closing the wound and 3 hours postoperation (repeated dose group),patients in the third group didn't receive TXA (control group).The postoperative blood loss via drainage,the total blood loss,the hidden blood loss,the postoperative hemoglobin concentration at different times and the numher of patients need blood transfusion were recorded.All patients were observed for detecting deep vein thrombosis (DVT) by the color doppler ultrasonography within 5 days postoperation,and the symptomatic DVT and pulmonary embolism (PE) were observed within 90 days postoperation.Results The blood loss via drainage was significantly less in the single dose group (273.6±99.6 ml) and repeated dose group (168.5±80.8 ml) compared with the control group (447.2±101.9 ml),and it was significantly less in the repeated dose group than the single dose group; the total blood loss was significantly less in the single dose group (959.1±291.7 ml) and repeated dose group (818.7±206.9 ml) compared with the control group (1 100.8±288.3 ml),and it was significantly less in the repeated dose group than in the single dose group; there was no differ ences about the hidden blood loss among the three groups.The hemoglobin concentration was significantly higher in the single dose group and repeated dose group than in the control group in day 1,3 and 5 postoperation; and it was significantly higher in the repeated dose group compared with the single dose group.The ratio of transfusion was significantly less in the single and repeated dose groups than in the control group,but no differences exists between the single dose group and repeated dose group.There was no DVT in all of the three groups within 5 days postoperation,and there was no symptomatic DVT and PE in all of the three groups within 90 days.Conclusion 10 mg/kg of TXA infused intravenous before closing the wound is effective and safe in TKA,another dose 3 hours postoperation is much more effective and will not increase the danger of DVT and PE.
