ABSTRACT
Objective To evaluate the blood-saving effect of tranexamic acid in elderly patients undergoing total hip replacement.Methods One hundred and sixty ASA Ⅱ or Ⅲ patientss of both sexes,aged 65-70 yr,with a body mass index of 16-22kg/m2,undergoing total hip replacement,were randomly divided into 2 groups(n =80,each)control group(group C)and tranexamic acid group(group T).Anesthesia was induced with midazolam,fentanyl,etomidate and atracurium.The patients were tracheal intubated and mechanically ventilated.PEr CO2 was maintained at 35-45 mm Hg.Aneslhesia was maintained with propofol,remifentanil and atracurium.Before the skin incision,tranexamic acid 15 mg/kg was infused over 15 m in in group T,while the equal volume of normal saline was given instead in group C.Hemoglobin(Hb),platelet count(PLT),prothrombin time(PT),and activated partial thromboplastin time(APTT)were monitored during operation to guide blood transfusion.Intraoperative and postoperative blood loss and allogeneic blood transfusion were recorded.Postoperative complications were also recorded.Results There was no significant difference in the amount of intraoperative blood loss between the two groups(P > 0.05).The amount of postoperative blood loss was significantly smaller and less allogeneic red blood cell was transfused in group T than in group C(P < 0.05).No complications occurred after operation in either group.Conchusion Tranexamic acid has blood-saving effect in elderly patients undergoing total hip replacement,but the clinical value is limited.
