Comparison of the effects of different blood conservation techniques in elderly patients undergoing total hip arthroplasty
Abstract
Background: To probe into the influences of different blood conservation techniques on the postoperative coagulation function and prognosis of elderly patients receiving Total Hip Arthroplasty (THA).
Methodology: A total of 60 patients were randomly divided into Autologous Blood Transfusion (ABT) group (n=30) and ANH group (n=30). For patients in the ABT group, an autologous blood recovery machine was used to recover, wash and filter the surgical field blood. For those in the Acute Isovolumic Hemodilution (ANH) group, blood was collected preoperatively from the central vein and stored in a citrate anticoagulant blood storage bag, while the same amount of hydroxyethyl starch was injected into the peripheral vein to dilute the blood. After Mai bleeding steps of the operation were completed, the autologous blood of patients was transfused back in both groups. The clinical indicators of patients in each group were observed.
Results: 48 h after operation, the ANH group obtained a higher level of hemoglobin (Hb), shorter Activated Partial Thromboplastin Time (APTT), and a lower expression rate of platelet activating factor CD62P than the ABT group.
Conclusion: The ANH group exhibits higher content of hemoglobin and fewer platelet (Plt)activating factors produced than the ABT group, while no significant difference in the shortened length of hospital stays is found.
Keywords: Hip arthroplasty; blood transfusion; autologous; hemodilution; transfusion of red blood cells; platelet activating factors.
