Introduction
The current study was conducted to evaluate the effect of different applications of tranexamic acid (TXA) on perioperative blood transfusion rate and postoperative pain in unilateral total knee arthroplasty.
Methods
This prospective study included a total of 102 patients undergoing unilateral total knee arthroplasty in our hospital from November 2017 to October 2019. On the basis of different TXA administration methods, these patients were randomly assigned to a surface treatment group (50 cases were treated with intraoperative spraying and drug-soaked gauze to cover the wound combined with local injection into the articular cavity) and control group (52 cases were given TXA by intravenous drip combined with local injection into the articular cavity) by random number table method. Clinical data were recorded and evaluated in the two groups. A total of five surgeons participated in the study.
Results
In the surface treatment group, the operation time, hospital stay, tourniquet time, and blood transfusion rate were significant lower compared with the control group, and there was no significant difference in the incision length between the two groups. Our results showed that intraoperative blood loss, postoperative drainage, postoperative blood loss, total blood loss, and the incidence of deep venous thrombosis in the surface treatment group were significantly lower than those in the control group. Our results demonstrated that the surface treatment group reported significantly lower degree of pain compared with the control group at 1 day and 3 days after the operation. However, 7 days after the operation, the degree of pain in the surface treatment group did not differ significantly from that in the control group. In addition, the results of blood coagulation indexes showed that the values of prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), D-dimer (D-D), and hemoglobin (HGB) in the surface treatment group did not differ significantly from those in the control group before the operation (P > 0.05).
Conclusion
In terms of applications of TXA, the method of intraoperative spraying and drug-soaked gauze covering the wound combined with local injection into the articular cavity can reduce the amount of bleeding and the rate of blood transfusion, and alleviate the degree of pain with high safety profile.
