Canine blood transfusion in the UK. Part 1: theory – why, what, when and how?

Background : Transfusion therapy has been used in human and veterinary medicine for many years and is considered lifesaving, enabling us to successfully manage conditions which would previously have resulted in significant morbidity and mortality. The first report of a successful canine blood transfusion was in 1665 by Richard Lower and use in clinical veterinary practice has been reported for approximately 75 years. Accessibility of canine blood products across the world has increased considerably over recent years, with the first UK national animal blood bank (Pet Blood Bank UK) set up in 2007. The advent of veterinary blood banking has facilitated the use, and potentially the misuse, of blood products, and broadened research and knowledge in the field of veterinary transfusion medicine. Extensive research has identified complexities around transfusion medicine and challenged common transfusion practices. Aim of the article : This article provides a practical approach to canine transfusion medicine in the UK. The aim of this first article in our two‐part series is to identify what products are available in the UK and discuss when it is appropriate, and not appropriate, to use these. Future directions and specific medical conditions where controversy exist are also highlighted.
