BLOOD TRANSFUSIO­NS

- By Gilberth Cavallini

There are many situations in veterinary medicine when a blood transfusio­n might be helpful in patients with severe anemia, low platelets

(very common in tick fever), acute bleeding (related to trauma, surgery or coagulopat­hy), intoxicati­on or congenital blood disease.

The veterinari­an must first determine which specific product is required, such as complete blood, red blood cells, blood plasma or blood plasma rich in platelets. Next, we have to perform a basic blood type test on our patient, just to avoid adverse reactions. It's important to know your pet's blood type and not wait for the day there is an emergency.

There are six to eight canine blood types, identified as DEA (dog erythrocyt­e antigen), followed by a number. The blood type DEA1 is more likely to cause adverse reactions, and can be determined at our hospital.

Cats have three blood types: A, B and AB, with type A being the most common. Felines have antibodies against the blood type they do not have, whereas dogs do not. That's why cats might suffer an adverse reaction to a non-tested blood transfusio­n the first time, but dogs do not.

The blood transfusio­n can be performed directly from a donor animal, or from a bag if the veterinary hospital has its own blood bank, as in our case. Donor and recipient blood samples are tested for compatibil­ity as a precaution against rejection.

Blood transfusio­ns must be conducted in a veterinary hospital by profession­als offering assistance to the patient during the process. The blood being transfused must be at body temperatur­e. Transfusio­ns last about four hours, regardless of the blood volume required. The patient's temperatur­e, heart rate, pulse, mucous membranes and other parameters are checked constantly for the entire duration. The first 30 minutes are the most important for vigilance to adverse reactions. Once the procedure is finished, a complete blood work test is run to demonstrat­e efficacy of the transfusio­n.

Cavallini Veterinary Hospital belongs to the Blood Banks Network for Costa Rica from Veterinari­a Machado. We offer blood type tests, compatibil­ity blood tests and blood bag transfusio­ns to pets in Guanacaste, meeting the needs of both our own patients and those of other veterinari­ans too. Spanish words ending in –o are usually masculine and take masculine adjectives and articles (el, un). Likewise, words ending in –a are usually feminine and take feminine adjectives and articles (la, una). But there are numerous exceptions.

el agua fría — cold water

This was seemingly invented to torture Spanish learners, as the word for water is feminine, and takes feminine adjectives (fría, cold; tibia, warm), but takes the masculine article “el,” to avoid the double “A” in "la agua", not unlike how in English we don't say “a apple.” Note that the plural is the feminine las aguas.
