Abstract:
BACKGROUND: Tranexamic acid has been used to reduce bleeding after total knee arthroplasty in patients for the reason of big trauma and blood loss. Diabetes mellitus patients may have the poor ability to resist infection and heal tissue and vascular lesions. There are still no relevant literature reports about whether the application of tranexamic acid will achieve hemostasis and does not increase the risk of venous thrombosis of lower limbs.OBJECTIVE: To evaluate the efficacy and safety of tranexamic acid on perioperative blood loss in osteoarthritis or rheumatoid arthritis patients complicated with type 2 diabetes mellitus during total knee arthroplasty.METHODS: One hundred patients with the diagnosis of osteoarthritis or rheumatoid arthritis patients complicated with type 2 diabetes mellitus were selected between January 2013 and January 2015. Among all the subjects, 46 patients who received the operation before January 2014 served as the control group and 54 patients who received the operation after January 2014 were selected as the treatment group. Patients in the treatment group received 15 mg/kg tranexamic acid dissolved in 250 mL normal saline by fast intravenous infusion before the end of the operation. The patients in the control group just received 250 mL normal saline. Perioperative bleeding, blood transfusion, hemoglobin, hematocrit and coagulation index level were compared between the two groups, and deep venous thrombosis of lower limbs was observed.RESULTS AND CONCLUSION: (1) The postoperative drainage, hidden blood loss, total blood loss, transfusion volume,and transfusion rate in the treatment group were lower than that in control group (P < 0.05). (2) The levels of hemoglobin and hematokrit in the two groups were not significantly different, but decreased at 3 hours, 1 and 3 days after the surgery,and increased at 5 days postoperatively, but still lower than preoperatively. The levels of hemoglobin and hematokrit in the treatment group were significantly higher than that in the control group at different time points postoperatively (P <0.05). (3) Prothrombin time, activated partial thromboplastin time, and fibrinogen were not significantly different preoperatively, during tourniquet removal, at 3 hours, 1 and 5 days postoperatively between the two groups. D-dimer levels were not significantly different preoperatively and during tourniquet removal in both groups, but increased at 3 hours, 1 and 5 days postoperatively; moreover, D-dimer levels were significantly lower in the treatment group than in the control group (P < 0.05). D-dimer levels were not significantly different between the two groups at 5 days after surgery. (4)Deep venous thrombosis of lower limbs was not visible in double lower limb venous ultrasonography in both groups at 5 days and 1 month postoperatively. (5) To decrease the blood loss, intravenous infusion of 15 mg/kg of tranexamic acid during total knee arthroplasty before tourniquet removel is effective and safe in osteoarthritis or rheumatoid arthritis patients complicated with type 2 diabetes mellitus.
