Detailed Description
Total knee arthroplasty (TKA) is associated with considerable blood loss and increasing needs for allogenic blood transfusion. Previous studies demonstrated a transfusion rates ranging from 6% to 38% after standard TKAs. Transfusion carries significant risks of cardiopulmonary embarrassment, disease transmission, immunological reaction and postoperative infection.
The major causes of postoperative blood loss following TKA are attributed to surgery itself which induces a considerable activation of the coagulation cascade and local fibrinolysis, the latter is further enhanced after release of the tourniquet at the end of surgery. Tranexamic acid (TXA), an inhibitor of fibrinolysis, was reportedly effective reducing blood loss after standard TKA. Previous experiences in minimally invasive (MIS) TKA showed that intraoperative infusion of TXA reduced 45% of postoperative blood loss and needs for transfusion from 20% to 4%. However, the safety to use TXA systemically in TKAs especially in high risk patients remains controversial. A recent study by Nishihara et al. demonstrated that use of TXA in total hip arthroplasty did not appear to affect the prevalence of either proximal DVT or PE. Another study by Xie J et al. also showed the incidence of postoperative VTE was unchanged when TXA was administered in primary unilateral TKA, but in their study the total occurrence of vascular occlusive events was statistically significantly higher (17.55% Vs 9.35%, p < 0.001) in the TXA group. However, in this two studies the patient with high risk of thromboembolic events (ischemic heart disease, chronic renal failure on hemodialysis, cerebral infarction, previous VTE disease, thrombophilia associated with genetic diseases) were excluded.
The investigators believe the use of hemostatic agent topically in patients with high risk of thromboembolism can avoid its systematic effect and decrease its potential perioperative risk of thromboembolic complications (arterial thrombosis, myocardial infarction and pulmonary embolism). On the other hand, thrombin-based hemostatic agents, Tisseel®, have been widely used in surgical procedure including gynecology, general surgery, and orthopedics which were still attracting the attention and interest of multitudinous surgeons. Some recent studies demonstrated that topic use of Tisseel® in primary TKA can reduce hemoglobin decline and calculated total blood loss after TKA and is not related to adverse reactions or complications such as wound infection, venous thromboembolism events(VTE). But there were another studies showed Tisseel® does not reduce blood loss in TKA procedures.
The purpose of this study therefore is to conduct a prospective randomized controlled trial to investigate the blood-conservation effect of the topic hemostatic agents and their safety in a primary TKA procedures in patients with risk of thromboembolic events. The first group by topical Tisseel and intravenous TXA application, and the second group of placebo IV TXA then observe whether there is difference in the blood-conservation effect by total blood loss calculation, hemoglobin loss and transfusion requirement among different groups.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Total blood loss after operation
Time Frame: from the operation to the postoperative day 3
|
Total blood loss was calculated according to Nadler et al., which used maximum postoperative reduction of the Hb level adjust for weight and height of the patient.
The formula is as follows, Total blood loss = (Total blood volume x [change in Hb level / preoperative Hb level])x1000+volume transfused
|
from the operation to the postoperative day 3
