ABSTRACT
Objective To investigate the effect of intravenous injection of tranexamic acid on reducing bleeding effect in invasive total hip replacement.Methods In our hospital from April 2015 to April 2016, 50 cases of total hip joint replacement patients as the object of study, patients were randomly divided into observation group and control group, 25 cases in each group.The control group were injected with 0.9% NaCl injection;observation group received intra-articular injection of tranexamic acid after suture, the transfusion volume of blood, complications, hemoglobin concentration, and rate of blood transfusion were compared between the two groups.Results The rate of blood transfusion in the control group was 52.0%, significantly higher than that of the observation group (24.0%), and the difference was statistically significant (χ2 =4.16, P0.05).Conclusion Tranexamic acid is the main method for prevention of postoperative bleeding, but could not reduce postoperative complications.
