Peri-operative anemia is a common condition encountered in adult surgical patients. It is increasingly recognized as a predictor of post-operative morbidity and mortality. Evaluation and treatment of anemia pre-operatively can reduce transfusion needs and potentially improve outcomes in surgical patients. This article discusses anemia optimization strategies in peri-operative setting with special focus on use of intravenous iron therapy. Additionally, the authors describe the role of transfusion medicine and best practices around red blood cell, platelet, and plasma transfusions.

Goal-directed administration of blood components including red cells, platelets, plasma, and factor concentrates plays a critical role in the management of intraoperative coagulopathy. Increasingly commonly used, purified and recombinant factor concentrates are being recognized for their logistical advantages and potentially superior efficacy. Three- and four-factor prothrombin concentrates, fibrinogen concentrates and activated factor VII have an evolving evidence base relative to frozen plasma and cryoprecipitate.

Patient blood management is the umbrella term for a suite of initiatives designed to optimise blood product usage, minimise transfusion needs, and ensure appropriate and evidence-based transfusion practices. In this review we summarise published economic evaluations of patient blood management to determine whether they represent good value for money. We identified 54 economic evaluations of patient blood management, the majority of which had positive cost-effectiveness conclusions.

Preoperative anemia affects one-third of patients undergoing major surgery and is associated with worse perioperative and postoperative outcomes; including length of hospital stay, allogeneic blood transfusion, morbidity, and mortality. Iron deficiency is the most common cause of anemia, and associative data suggests that preoperative correction of iron deficiency anemia could improve postoperative patient outcomes. However, data from randomized controlled trials (RCTs) do not appear to support the routine use of iron therapy to treat preoperative anemia.

Patients with cancer who receive allogeneic red blood cell transfusions are at risk of adverse reactions of varying severity. One of these reactions is immunomodulation, also known as transfusion-related immunomodulation. With the exact mechanism of transfusion related immunomodulation being unclear, storage lesions (both the cellular and cytokine component) are considered a major contributor.

Anemia and red blood cell transfusion are associated with adverse outcomes. Large randomized trials have demonstrated that restrictive transfusion strategies can safely reduce patient exposure to transfusion, forming a foundational pillar of patient blood management. The restrictive transfusion thresholds in these trials ranged from 7 to 8 g/dL for different populations and this variability is reflected in recent guideline recommendations for transfusion triggers.
