Canine blood transfusion in the UK. Part 2: putting theory into practice

Background : Transfusion therapy has been used in both human and veterinary medicine for many years. As veterinary transfusion medicine has progressed, it has highlighted the intricate nature of blood products and their administration. Ongoing research challenges conventional practices, uncovering complexities related to compatibility, storage, administration and the nuanced profiles of potential adverse reactions. This expanding body of evidence emphasises the necessity for evidence‐based guidelines while also highlighting the need for continued research and awareness regarding the safe and effective use of blood components in veterinary patients. Aim of the article : This article – the second in a two‐part series – provides a practical approach to canine transfusion medicine in the UK, discussing the relevance of canine blood groups and establishing when crossmatching is required. The practical aspects of collecting blood from a donor and performing blood transfusions in practice are also covered, alongside the risks, relevant monitoring, and the identification and management of transfusion reactions.
