Targeted preoperative autologous blood donation in total knee arthroplasty reduces the need for postoperative transfusion.

ABSTRACT:

Background

Preoperative donation of autologous blood has been widely used to minimize the potential risk of allogeneic transfusions in total knee arthroplasty. A previous study from our center revealed that preoperative autologous donation reduces the allogeneic blood exposure for anemic patients but has no effect for non-anemic patients.

Questions/purposes

The current study investigates the impact of a targeted blood donation protocol on overall transfusion rates and the incidence of allogeneic blood transfusions.

Methods

Prospectively, 372 patients undergoing 425 unilateral primary knee replacements were preoperatively screened by the Blood Preservation Center between 2009 and 2012. Anemic patients with a hemoglobin level less than 13.5 g/dL were advised to donate b
