Objective: To compare the experience obtained in allogenic and autologous blood transfusion used in hip arthroplasty.Methods: 188 cases of hip arthroplasty were retrospectively analyzed

and the patients were divided into three groups.Group A(62 patients)received preoperative storage and transfusion of autologous blood during the operation.Group B(76 patients) received reinfusion of shed blood during the operation.Group C(50 patients)only received allogenic blood transfusion.Results: In group A and B

64.5%(40/62) and 61.8%(47/76)of the patients

respectively passed perioperative period successfully without allogenic blood transfusion.However the proportion in group C was 32%(16/50).The quantity of allogenic blood transfusion used in Group C was significantly higher than that in Group A and B(P<0.05).Before or after autologous blood storage

there were no significant differences in hemoglobins and hematocrits in Group A.In Group B

the blood constituent almost reached normal one week after operation.Conclusions: Autologous blood transfusion used in hip arthroplasty is very safe

economic

with less side reactions and high quality blood transfusion.Reinfusion of autologous shed blood can be advised to use for its safety

convinence and effectiveness in the majority of arthroplasty cases.
