"Several randomized controlled trials have concluded that a restrictive transfusion strategy may be non-inferior to a liberal threshold in the management of perioperative anemia. As such, adequate oxygen delivery may still be accomplished while mitigating the deleterious effects of allogeneic transfusion.
Improved cardiac surgical patient outcomes can be realized through the establishment of perioperative blood management programs. Unnecessary and uninformed blood transfusions can be avoided by the endorsement of evidence-based protocols, timely sharing of quality performance measures, and the engagement of all key stakeholders in promoting comprehensive blood management strategies. Cardiovascular perfusionists play an essential role in minimizing the potential risks of allogeneic exposure. Several interventions should be considered by the perfusion team to reduce excessive hemodilution, preserve red cell mass, and recover shed blood lost during surgery."
