'''This two-year-old, FeLV-positive, entire male cat presented for anorexia and lethargy. Physical examination revealed: pale mucous membranes; RR – 80 bpm; HR – 240 bpm. PCV – 70%; TS – 8.0 g/dl.'''

<FlashCard questions="3">
|q1=Which infectious disease would be likely to be causing the anemia in this FeLV–positive cat?
|a1=
Haemobartonella felis is a common cause of anemia in FeLV positive cats.
|l1=
|q2=Would you expect the anemia to be regenerative or non-regenerative?
|a2=
Typically, FeLV is associated with macrocytosis; however, cats with H. felis infection may be normocytic (MVC – 60–70 fl) and non-regenerative.
|l2=
|q3=Describe your protocol for transfusing this cat.
|a3=
Generally, whole blood is administered to cats requiring RBC transfusion.
Whole blood can be withdrawn from a donor cat by sedating the donor with ketamine (2–4 mg/kg i/v). Typically, approximately 50–60 ml of blood can be withdrawn from the donor cat into a syringe containing 9 ml of acid citrate dextrose (7 ml of blood/ml of acid citrate dextrose).
The volume and rate of blood administered varies with the patient’s clinical signs and laboratory data.
In general, 2 ml/kg of whole blood will increase the patient’s PCV by 1%. The transfusion rate for whole blood should be 5 mg/kg during a 4-hour period or, if the patient is hypovolemic, 5 ml/kg/hour.
The first 10 ml should be given slowly over a 15 minute period to observe for adverse reactions.
Blood should always be administered through an appropriate filter and administration set designed to retain blood clots and other debris.
