Interventions to minimize blood loss and transfusion risk in spine surgery: A narrative review

Abstract

Blood loss is an inevitable reality of spine surgery. Excessive loss is associated with increased morbidity and mortality and is frequently combated with allogeneic blood transfusions. Transfusions themselves are associated with increased morbidity, including circulatory overload, lung injury, and acute kidney injury. It is therefore incumbent upon the practicing spine surgeon to be aware of evidence-based interventions capable of reducing blood loss and the risk of transfusion. Here we review the available literature and make recommendation based upon the available evidence.
