Abstract
PurposeTo compare the hemostatic effect and risk of thrombosis between tranexamic acid and epsilon-aminocaproic acid.MethodsA retrospective study of 140 cases of joint replacement, including 93 cases in the tranexamic acid (TXA) group and 47 cases in the epsilon-aminocaproic acid (EACA) group. TXA or EACA was injected intravenously 30 minutes before surgery, and TXA or EACA was infused into the joint cavity after the wound was closed. The drainage, blood loss and plasma albumin loss were observed after operation.ResultsThe postoperative hemoglobin loss in the two groups was 19.1±11.4g/L, 20.3±13.6g/L, P>0.05. However, the drainage volume of the TXA group was less than that of the EACA group, which were 103.3±92.1ml and 117.4±120.9ml, respectively, P<0.05. The blood transfusion rate in the TXA group was higher than that in the EACA group, 14% and 34%, respectively, P<0.05. The postoperative plasma albumin loss of the two groups of patients was 7.4±8.0g/L and 7.3±5.5g/L respectively, P=0.05.ConclusionsThe hemostatic effect of TXA was slightly better than that of EACA, and the proportion of transfusion of TXA was lower.Level of Evidence: Level III
