In our hospital, we often treat patients with acute bleeding, for example, after auto-injuries, patients with anemia, clotting disorders, poisoning, etc. Thanks to our advanced equipment, we are able to instantly evaluate animal blood count and decide on the need to compensate for the losses via a blood transfusion.
For several years, we have had blood transfusions available. Previously, the first transfusions were routinely done without blood typing the donor and recipient blood group, unfortunately, there were oftentimes allergic reactions. The response of the organism is mainly attributed to the reaction of the DEA 1.1 negative recipient to the blood of the DEA 1.1 positive donor. We now have dog blood, blood plasma and blood derivatives tested for the DEA 1.1 blood group and tests to determination the ideal recipients.
We have donor blood and blood derivatives in the amounts that covers the needs of our hospital. Our donors are most often the four-legged friends of our clients and are involved in saving other patients.
By signing up to our donor registry, you can help too!
Donor requirements are dogs over 30kg, in good health and with a calm personality.
Blood collection is performed without the need for sedation. You can get the specific details in person, by phone or by email. For now, the blood bank is unavailable to cats. However, we are able to immediately identify the blood group and participate in the finding a cat donor.

In the last ten years, there has been a rapid development of veterinary medicine for dogs and cats in our country. With the changing relationship to animals and the growing financial possibilities of their owners, various fields of veterinary medicine are developing, especially ones who have not developed as fast over the years. One method that is now standard is the administration of blood derivatives. That is, the administration of currently readily available whole blood, but also fresh frozen plasma, and other derivatives.
Reasons For Transfusion
As with human patients, sometimes there are situations leading to large blood loss. Examples include injuries associated with injuries to large vessels or internal organs. Furthermore, poisoning, disorders of blood clotting (coagulopathy), some autoimmune diseases, pancreatitis and so on.
A known problem associated with blood transfusions is the recipient's immune response to donor cells. As with humans, dogs also have blood groups. More than 12 types are currently being described. In practice, however, the DEA 1.1 blood group positive and negative is particularly important. Mostly, the first administration of blood is not associated with the onset of a severe post transfusion reaction, but several days after the transfusion is administered, antibodies against the blood group do not coincide with the recipient's blood group and further administration of the blood is very risky. Therefore, each transfusion should be preceded by an examination of the recipient's blood for the DEA 1.1 antigen and only the appropriate blood group should be administered. Conducting a so-called cross test does not in any way replace the test for the blood type of a dog.
In the past, so-called direct transfusions have often been used, where blood from the donor is drawn into syringes and applied directly to the recipient. These are almost never in use now. A simpler, faster and more practical way is to collect whole blood into special transfusion bags and then administer it to the recipient via the transfusion set. This is probably the most common method today. A large breed dog can donate 400 - 500 ml of blood without any harm. This amount is sufficient to save the life of a small to medium-sized dog after severe blood loss. This blood can be stored for a certain period of time. However, some of the blood components decompose gradually during storage. The advantage is therefore the processing of whole blood into blood derivatives. Separating the individual blood components yields products that are more useful for specific problems, and their shelf life is higher.
At present, there are already veterinary workplaces offering blood bank services in the Czech Republic. They consist of distributing blood derivatives for their own use or offering them to other workplaces. The advantage of separating whole blood into individual components, is in the possibility of specialized use of the derivative according to the current indication and also in the fact that the offered blood is already tested for its specific blood groups. As donors, only dogs that are carefully screened for their health should be used as donors.
Transfusion medicine is now a standard of veterinary care for dogs and cats. Its use is irreplaceable, in many cases it can be a vital, life-saving treatment.
