The Reinfusion of Autogenous Shed Blood After Unilateral Total Knee Arthroplasty Using the Perioperative Autologous Transfusion System OrthoPAT.
This study aims to explore the use of postoperative autogenous shed blood reinfusion using Orthopedic Perioperative Autotransfusion System (OrthoPAT) system in treating patients undergoing unilateral total knee arthroplasty (TKA). Fifty patients undergoing unilateral TKA were enrolled as the experimental group A and were treated with reinfusion of autologous shed blood within 6 hours after unilateral TKA using OrthoPAT. Accordingly, 50 patients undergoing unilateral TKA were selected as the experimental group B and were treated with allogeneic blood transfusion. Different indexes were observed at different times. Patients in both groups had relatively stable hemodynamics, and there was no postoperative coagulopathy. Prothrombin time, thrombin time, and activated partial thromboplastin time were lower, and fibrinogen was higher in group A than that in group B 24 hours after surgery (all P < 0.05). White blood cell, red blood cell, hemoglobin, hematocrit (Hct), and platelet count levels in group A were lower than those in group B 12 hours after surgery (all P < 0.05). The postoperative complications of the 2 groups have significant difference (P < 0.05). Postoperative autogenous shed blood reinfusion using OrthoPAT system in the treatment of patients undergoing unilateral TKA may improve the coagulation function of patients and reduce the rejection caused by standard allogeneic blood transfusion.
