How do they perform blood transfusions on cats? - briefly
Performing blood transfusions on cats involves carefully matching the donor's and recipient's blood types to prevent adverse reactions. The procedure typically includes administering the donated blood intravenously while closely monitoring the cat for any signs of complications.

Blood transfusions in cats are critical procedures typically performed when a cat has lost a significant amount of blood or has anemia that cannot be managed with medication alone. The process involves several steps, each crucial for ensuring the safety and effectiveness of the transfusion.
Firstly, before any transfusion, a thorough examination is conducted to determine the cause of the anemia or blood loss. This may include tests such as a complete blood count (CBC), biochemical profile, and urinalysis. Identifying the underlying condition is essential for appropriate treatment beyond just the transfusion.
The next step involves selecting a compatible donor cat. While cats have different blood types, type A is the most common, and it is generally safe to use as a universal donor. However, some cats may require specific matching, especially in cases where multiple transfusions are needed or if there's a known history of adverse reactions.
Preparation for the transfusion includes gathering necessary equipment such as intravenous catheters, extension sets, and fluids. The cat receiving the transfusion is typically placed on an intravenous drip to ensure proper hydration and maintain blood pressure during the procedure. This also helps in preventing clotting within the catheter.
The donor cat is sedated to minimize stress and discomfort, and a small amount of blood (usually 10-20 ml per kilogram of body weight) is drawn into a sterile collection bag containing an anticoagulant like citrate phosphate dextrose adenine (CPDA). This step ensures that the blood remains viable for transfusion.
For the recipient cat, an intravenous catheter is placed, usually in the jugular or cephalic vein. The donor blood is slowly administered over a period of 2-4 hours to allow the recipient's body time to adjust and minimize the risk of adverse reactions.
Throughout the transfusion, close monitoring is essential. This includes regular checks on the cat's temperature, heart rate, respiratory rate, and blood pressure. The color and consistency of the urine are also observed for any signs of hemolysis or other complications.
Post-transfusion care involves continuing to monitor the cat closely for several hours after the procedure. This is crucial to detect any delayed adverse reactions. Follow-up blood tests may be conducted to evaluate the effectiveness of the transfusion and to plan further treatment as needed.
In conclusion, performing a blood transfusion on cats requires meticulous preparation, careful selection of a compatible donor, and diligent monitoring throughout the procedure. This ensures that the cat receives the necessary blood components safely and effectively, contributing to their overall recovery.
