Strategies to avoid intra-operative blood transfusion

Abstract

Transfusion of donor blood is sometimes unavoidable during the surgical episode. However, it is associated with increased morbidity and mortality, whilst interventions that reduce the need for donor transfusions have a positive impact on outcome. The principles underpinning reducing the need for transfusion are collectively known as ‘patient blood management’ which incorporates three pillars: anaemia management, limitation of blood loss and restrictive transfusion triggers. When used in combination, these principles appear the most effective way to limit the impact of surgical blood loss and reduce allogenic blood transfusions.
