Abstract:
Objective To observe the effects of acute normovolemic hemodilution(ANH) plus tranexamic acid on blood loss and blood transfusion in patients with total knee replacement.Methods 98 cases of patients with total knee replacement were divided into ANH group and combination group by computer randomization,49 cases in each group.ANH was performed in ANH group,and ANH plus tranexamic acid was given in combination group.The changes of hemoglobin(Hb),red blood cells deposited(Hct),platelet count(PLT) were observed before and after autologous blood transfusion in two group.The changes of prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT),fibrinogen(FIB),D-dimer were observed at preoperative and postoperative in two group.The amount of blood loss and allogeneic blood infusion,the urine volume and the postoperative flow volume were recorded in two groups.Results The average levels of Hb,Hct after autologous blood transfusion in combination group were higher than those in ANH group,the differences were statistically significant(P<0.05).The average level of D-dimer at postoperative in combination group were higher than that in ANH group,the difference was statistically significant(P<0.05).The amounts of blood loss and allogeneic blood infusion,the postoperative flow volume were lower than those in ANH group,the differences were statistically significant(P<0.05).Conclusion The joint application of ANH and tranexamic acid can effectively reduce the amounts of blood loss and allogeneic blood infusion in patients with total knee replacement,and has a certain clinical value.
