Pillar III--optimisation of anaemia tolerance.

In the case of acute bleeding, the use of the anaemia tolerance of a patient enables the physician to either avoid blood transfusions or delay them after bleeding has ceased. This concept is the cornerstone of the third pillar of modern patient blood management programmes. Its efficacy depends on the degree of utilisation of anaemia tolerance, which is not constant but depends on the compensatory capacity of the individual patient in a given situation. Fortunately, the specifications of anaemia tolerance can be influenced by the anaesthesiologist. This article presents the concept of anaemia tolerance and highlights the options for how anaemia tolerance can be optimised in the pre-, intra-, and postoperative periods.
