Why is blood transfused in dogs? - briefly

Blood transfusions in dogs are performed to replace lost red blood cells and plasma due to trauma, surgery, or disease. This helps maintain adequate oxygen supply and fluid balance, preventing shock and supporting recovery.

Why is blood transfused in dogs? - in detail

Blood transfusions in dogs are performed for several critical reasons, each of which plays a crucial role in maintaining the health and well-being of the animal.

Firstly, blood transfusions are essential in treating anemia, a condition characterized by a deficiency of red blood cells or hemoglobin. Anemia can result from various causes such as blood loss due to trauma, surgery, or internal bleeding; bone marrow disorders that inhibit the production of red blood cells; and certain diseases like immune-mediated hemolytic anemia, where the body's immune system destroys its own red blood cells. In severe cases, anemia can lead to organ failure and even death if left untreated. A transfusion replenishes the depleted red blood cell count, ensuring adequate oxygen supply to vital organs.

Secondly, blood transfusions are used in emergency situations where rapid blood loss occurs. This is common in cases of severe trauma, such as road accidents or internal bleeding from conditions like gastric ulcers or tumors. Blood transfusions provide immediate support by restoring the lost volume and preventing shock, which can be life-threatening.

Thirdly, blood transfusions are crucial during surgical procedures that involve significant blood loss. Surgeries such as splenectomies (removal of the spleen), certain types of cancer surgeries, or major orthopedic procedures often require a substantial amount of blood to be replaced. Transfusing blood during and after these operations helps maintain stable vital signs and promotes faster recovery.

Fourthly, blood transfusions are sometimes necessary in dogs with specific clotting disorders that prevent their blood from coagulating properly. These conditions include von Willebrand disease and hemophilia A and B. Transfusing fresh frozen plasma (FFP) or whole blood can provide the necessary clotting factors to stabilize the dog's condition until a definitive treatment plan is established.

Lastly, blood transfusions are occasionally used in dogs undergoing chemotherapy or radiation therapy for cancer treatment. These therapies can cause bone marrow suppression, leading to a decrease in red blood cell production. Transfusions help maintain adequate red blood cell counts and prevent anemia-related complications during the course of treatment.

In summary, blood transfusions in dogs are a lifesaving measure used to treat various conditions that affect red blood cells, clotting factors, or cause significant blood loss. These procedures are vital for maintaining the dog's health and ensuring a successful recovery from illness or injury.
