There are specialized blood products for situations in which cells or substances in the unit need to be reduced or removed:. This reduces the risk for allergic transfusion reactions. Here is a brief overview of the products and services available: PRBCs are used to replace red cell mass when tissue oxygenation is impaired by acute or chronic anemia.
One of the separated portions is withdrawn and the remaining components are retransfused. There are a variety of blood products, pharmacologic agents, and procedures that can be utilized to treat anemia, thrombocytopenia, and bleeding disorders.
The expected incremental increase in platelet count for adults is 30 - 60 K for each "six pack" of platelets Normal saline is used when providing vascular access and fluid volume when transfusing other products and pharmacologic agents. There is indication that the patient needs additional oxygen carrying capacity.
Normal saline is more readily accessible than albumin or FFP, it is relatively inexpensive, and it does not have the risk of viral transmission.
Return to the tutorial menu. They must be used in 5 days.
Indications for Blood Product Usage There are situations identified in which blood products may be needed: Packed RBCs: Cryoprecipitate is used for hypofibrinogenemia, vonWillebrand disease, and in situations calling for a "fibrin glue.
Pooled platelets from multiple donors from whole blood collections are cheaper to produce but the exposure to the recipient increases.
Here is a brief overview of the products and services available:. This may reduce the risk for febrile transfusion reactions, may help prevent alloimmunizaton to MHC HLA donor antigens, and help reduce the risk for cytomegalovirus CMV infection.
There are specialized blood products for situations in which cells or substances in the unit need to be reduced or removed: The recipient's HLA type can be "matched" to a platelet donor with a similar HLA type to deal with problems of HLA alloimmunization in patients with prior transfusions or pregnancies. Albumin is useful as a plasma expander. The components which are separated off and withdrawn include: Blood Bank tutorial menu.
