USE OF A BOVINE HEMOGLOBIN PREPARATION IN THE TREATMENT OF CYCLIC OVARIAN HEMORRHAGE IN A MINIATURE HORSE

Anemia that was secondary to ovarian hemorrhage in a 4-year-old miniat ure horse mare was treated prior to laparotomy with polymerized ultrap urified bovine hemoglobin (PUBH). Two previous whole-blood transfusion s had resulted in acute transfusion reaction, and a suitable blood don or could not be found among 9 horses, necessitating use of the blood s ubstitute. Subsequent blood typing revealed the mare to be Aa-negative , with allo-antibodies against Aa in serum. Serious adverse reactions were not observed after infusion of PUBH, and the mare recovered. Alth ough the safety and efficacy of using PUBH in horses has not been esta blished, PUBH may prove to be an excellent alternative to whole-blood transfusions, when indicated.
