QuestionAnswer
Define Blood Transfusion: The process of transferring whole blood or components of it from a donor to a recipient
What is the purpose of transferring blood? It is used to restore lost blood, to improve clotting time, to improve the ability of blood to deliver oxygenated blood to the body's tissues
Define erythrocyte Mature red blood cell
D: hemoglobin blood protein which transfers O2
D: Serum Liquid portion of blood
D: Plasma Yellow/straw protein of blood which transports nutrients, hormones, waste products, and clotting factors to the body's tissues
D: Hemolysis Breakdown of red blood cells ((Hem/o=blood -lysis=breakdown))
D: Anemia Less than normal levels of erythrocytes or hemoglobin ((determined by a reduced PCV))
D: Antigen A substance such a bacteria, viruses, and pollen, which produce an immune response because they are foreign to the body. "A substance the body regards as foreign."
D: Antibody A disease fighting protein produced by the body in response to the presence of a specific antigen.
D: Allergy An overreaction by the body to a particular antigen.
D: Anaphylaxis A severe response to a foreign substance. Develops acutely and may include tachycardia, swelling, blockage of the airways, etc.
D: Agglutination Clumping together of cells of particles...sign of IMHA (Immune Mediated Hemolytic Anemia)
D: Rouleax Erythrocytes stacked like coins; a normal finding in equines
D: Autoimmune Disease A disorder in which the body makes antibodies direct against ( attack) themselves.
Common physical finding of anemia are lethargy, weakness, pale mucous membranes, tachycardia, tachypnea, and a bounding pulse
In severe anemic state, a low grade systolic flow murmmer may occur secondary to: decreased blood viscosity
Prolonged tissue CRT is suggestive of: compromised tissue perfusion and shock, but may be difficult to assess in a anemic patient
Weak and rapid pulse suggests: severe dehydration and poor perfusion; a bounding pulse suggests anemia

_____________ may be seen on the blood film because of the intravascular ___________ of erythrocytes Schistocytes may be seen on the blood film b/c of the DESTRUCTION of erythrocytes (RBC's)
D: petechia small, pinpoint homerrhages often seen on the pinna and inguinal area
D: ecchymoses small hemorrhagic spot in the skin or mucous membranes forming a nonelevated, rounded or irregular, blue or purplish patch (ie. briuse)
D: epistaxis nosebleed
Clinical presentation of DIC may include (3), and prolonged bleeding following __________ or _________ petechia, ecchymosis, epistaxis; and prolonged bleeding following TRAUMA or SURGERY
D: Thrombus blood clot
D: Hematuria blood in the urine
Dogs have at least __ blood groups 19
D: DEA Dog Erythrocyte Antigen
Canine blood types are noted by its ___ and a _______ DEA and a NUMBER
This is the most common canine blood type DEA 1.1+
Dogs with the blood type ____ are considered to be the universal __________ 1.1+ = canine universal RECIPIENT
Canine blood type 1.1+ is the equivalent to a human blood type _____ 1.1+ is equivalent to human blood type A positive
Canine blood types ___ and ___ are said to be the universal ________ 1.1- or 1.2- = universal DONORS
Canine blood types ____ and ____ are simillar to human blood type A negative 1.1- and 1.2-
Cats are said to have __ blood types; __, __, and ___ Cats have 3 blood types; A, B, and AB
The most common feline blood type is A
Many purebred cats have __ blood type B
Most cats in North America, as well as DSH/DLH have __ blood type A
European cats have a higher percentage of __ blood type B
Cats have naturally occuring ______________ against the blood-type they lack, therefor there is no universal feline blood _______ Alloantibodies, no universal feline DONOR
Type AB cats can receive __ or __ blood with no clinical recations A or B
Cats may have a ________ reaction to the first transfusion Severe
Canine blood donors need to meet __________________ (9) prerequisites to donate blood Be in good physical condition, be screened for blood transmissible diseases, over a certain body weight, UTD on vaccines, be on HW prevention, have an adequate predonation PCV, must have a good temperment
Fresh whole blood contains a mixture of cellular components which includes (3) and plasma components (?) Erythrocytes, leukocytes, and platelets; plasma = liquid portion containing proteins and nutrients)
Fresh whole blood must be transfused within __ hours 4
Fresh whole blood is used to treat (6) hemorrhagic shock, bleeding disorders (due to thrombocytopenia or clotting factor deficiencies), anemia, surgical hemorrhage, and IMHA
D: IMHA Immune Mediated Hemolytic Anemia
What are two disadvantages of whole blood transfusions? 1. Limited resources - so separation of WB components permits a single donation to help mult patients; 2. Volume overload & pulmo edema vs component therapy
Packed Red Blood Cells is refrigerated _____ ______ that is ______________ and the ______ is removed Packed RBC's is refrigerated WHOLE BLOOD that is CENTRIFUGED and the PLASMA is removed
Packed RBC's is primarily used in patients with decreased _______ carrying capabilities Oxygen
