摘要

Postoperative shed autologous blood reinfusion techniques have been used for decades in total knee arthroplasty (TKA), but the effectiveness of this procedure is still a matter of debate. This multicenter retrospective study investigated the medical records of patients who underwent unilateral and bilateral TKA from January 1, 2015 to December 31, 2017 in three hospitals. According to whether postoperative shed autologous blood reinfusion was used, the patients were divided into the control group and the shed autologous blood reinfusion group. The volume of perioperative infusion of red blood cells and plasma, the blood transfusion-related costs, and the postoperative hospital stay were compared between the two groups of patients. A total of 200 unilateral and 74 bilateral TKA were included after successful matching. Among the patients who underwent unilateral TKA, the control group and the shed autologous blood reinfusion group had 95 and 91 patients, respectively, who received allogeneic blood infusion (P = 0.268). There was no significant difference in the number of units of allogeneic red blood cells infused (P = 0.154), while the transfusion-related cost was increased (P<0.001). The same phenomena were observed over the patients underwent bilateral TKA. Shed autologous blood reinfusion does not reduce the need for infusing allogeneic red blood cells. In addition, the procedure increases patient expense and may also lead to an extended postoperative hospital stay.
