Autologous blood transfusion following an allogenic transfusion reaction in a case of acute anaemia due to intra‐abdominal bleeding

Abstract

Summary This report describes the use of an autologous transfusion to temporarily improve the oxygen carrying capacity in a case of haemoabdomen. The horse required multiple blood transfusions but use of allogenic transfusions was hindered by a severe adverse reaction. The blood previously lost into the abdomen was drained and returned to the circulation without observed adverse effects. Autologous blood transfusion is a technique which can be used alone, or in addition to, allogenic blood transfusions in selected cases of acute blood loss in horses.
