Abstract: Objective Research the application value of deep autologous blood in orthopedic joint replacement.Methods A retrospective analysis of 283 cases of orthopedic joint replacement patients transfusion cases,according to whether the depth of self-storage of blood into allogeneic transfusion group and autologous transfusion group. comparative analysis of two groups of patients preoperative parameters,intraoperative bleeding,Intraoperative autologous / allogeneic blood transfusion,postoperative drainage,hidden blood loss,postoperative recovery and other parameters.Results Two groups of patients recovered well after surgery,There were no complications after operation. The total amount of blood transfusion in both groups was basically the same; Two groups of patients in different replacement of dominant bleeding,there was no difference in the P values in occult blood loss,preoperative hemoglobin levels and postoperative hospital stay were greater than 0.05. When two groups of patients with double hip and knee replacement were discharged from the hospital,the P values in hemoglobin levels were less than 0.05,the P values in autologous group was significantly higher than allogeneic group.Conclusion Depth of autologous blood can reduce allogeneic blood transfusion,there is no effect on patient surgery and postoperative recovery. It is especially suitable for unilateral arthroplasty.
