Effects of Different Regimens of Tranexamic Acid on Perioperative Bleeding and Postoperative Compliance of Simultaneous Bilateral Total Knee Arthroplasty / 中国药房

ABSTRACT

OBJECTIVE:To observe the effects of different regimens of tranexamic acid on perioperative bleeding and postoper-ative compliance of simultaneous bilateral total knee arthroplasty(TKA). METHODS:A total of 70 patients undergoing simultane-ous bilateral TKA in our hospital were randomly divided into control group and observation group,with 35 cases in each group. Control group was given Tranexamic acid injection 15 mg/kg 30 min before surgery. Observation group was given Tranexamic acid injection 15 mg/kg,30 min before surgery and 30 min before suturing incision. The operation duration,total blood loss,intraopera-tive blood loss,postoperative drainage as well as the levels of FIB,PT,APTT before trectment and 3 d after surgery,the occur-rence of postoperative compliance and ADR were observed and compared between 2 groups. RESULTS:There was no statistical significance in operation duration,intraoperative blood loss and rate of ADR between 2 groups (P>0.05). The total blood loss, postoperative drainage and the incidence of complications of observation group were significantly lower than those of control group,with statistical significance(P0.05). CONCLUSIONS:The application of tranexamic acid 30 min before simultaneous bilateral TKA and 30 min before the end of surgery can reduce perioperative bleeding and postoperative venous thromboembolism with good safety.
