Anaemia is common in intensive care and its causes multifactorial. Blood transfusion is not without risks and the efficacy of stored blood to increase tissue oxygenation has been questioned. ⋯ There is also evidence for a benefit with the use of leucocyte reduced transfusions. With exception for patients with ongoing bleeding, instabile angina, myocardial infarction or COPD during weaning, a restrictive regime with a haemoglobin concentration between 70-90 seems to be without risks.
