: The management of perioperative bleeding involves multiple assessments and strategies to ensure appropriate patient care. Initially, it is important to identify those patients with an increased risk of perioperative bleeding. Next, strategies should be employed to correct preoperative anaemia and to stabilise macrocirculation and microcirculation to optimise the patient's tolerance to bleeding. ⋯ The final draft guideline was posted on the European Society of Anaesthesiology website for four weeks for review. All comments were collated and the guidelines were amended as appropriate. This publication reflects the output of this work.

Perioperative anaemia is common. Physicians believe that patients at increased cardiac risk do not tolerate anaemia and, consequently, these patients receive transfusions earlier and more often. This practice runs counter to a growing body of evidence that perioperative red blood cell (RBC) transfusion is harmful The aims of this study were as follows: (i) to assess the effects of transfusion at moderate to severely low ranges of postoperative haemoglobin concentrations; and (ii) to assess whether transfusion was beneficial in patients at high cardiac risk within these haemoglobin ranges. ⋯ High cardiac risk was associated with increased incidence of anaemia, transfusion, and mortality. Red blood cell transfusion is associated with reduced mortality only in high cardiac risk patients with nadir postoperative haemoglobin concentration <80 g litre -1 . Transfusion, the main treatment for postoperative anaemia, does not appear to be associated with reduced postoperative mortality at higher nadir haemoglobin ranges.
