In transfusion-naïve cats receiving a type specific blood transfusion is cross-matched blood (major and minor) associated with an increased haematocrit development and reduction in acute transfusion reactions when compared with those receiving non-crossmatched blood?
Clinical bottom line
Category of research question
The number and type of study designs reviewed
Ten papers were critically reviewed. There were four retrospective case series, three prospective cross-sectional surveys, a retrospective cohort study, a prospective case series and a prospective randomised control trial.
Strength of evidence
It would appear that in the United Kingdom the incidence of non-AB transfusion reactions is low. A single study suggests that cross-matching may result in a greater improvement in haematocrit, but this is unlikely to be clinically significant. There is evidence to support the hypothesis that non-AB antigens (for example the Mik antigen) differ with geographic distribution.
Based on the information available it is it is challenging to establish a meaningful clinical conclusion on which to base a recommendation.
How to apply this evidence in practice
The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
