Pre-optimization of the anaemic patient. Issue 2 (February 2016) - Kotzé, Alwyn
Abstract: Preoperative anaemia is common. Its prevalence varies according to the population studied and the definition of what constitutes anaemia. Where the widely accepted definition of the World Health Organization is used (haemoglobin concentration (Hb) <130 g/l in men or <120 g/l in women), between 20% and 60% of surgical patients are found to be anaemic. Anaemia is well known to contribute to increased peri-operative risk. In contrast to the other well-known risk determinants (e.g. age, magnitude of surgery, the presence or absence of a cancer diagnosis, renal failure etc.) anaemia is potentially modifiable. This article will give an overview of the approach to a patient found to be anaemic before surgery.
