1 Blood Products and Transfusion Safety
Learn how to match blood products to clinical needs, handle them safely, and respond to suspected transfusion reactions.
Match the product to the clinical need
A transfusion replaces a specific blood component or substance, not “blood” in general. Select the product that addresses the patient's clinical problem, and use it only when indicated. Decisions should consider the patient's condition, risks, alternatives, and preferences—not a laboratory value alone—and must follow local transfusion-service procedures.
Choosing the wrong component may add risk without treating the problem. For example, symptomatic anemia may call for red blood cells, whereas bleeding with a significant clotting-factor deficiency may call for or a targeted factor product.
What each product provides
provide oxygen-carrying red cells. They are commonly used for clinically significant anemia that impairs oxygen delivery or to replace red cells during major blood loss. For a stable, nonbleeding adult, a common approach is one unit followed by reassessment, though individual needs vary.
support clot formation. They may be used to treat or prevent bleeding when platelet numbers are low or platelet function is impaired; a count alone does not determine the need for transfusion.
, such as fresh frozen , provides multiple clotting factors. It may be used for bleeding or risk of bleeding with a clinically significant clotting-factor deficiency when a specific factor treatment is unsuitable or unavailable. is not a volume expander or a general nutrition product.
provides concentrated fibrinogen and some other clotting proteins. It may be appropriate for low fibrinogen associated with critical bleeding or another appropriate clinical indication.
include albumin, immunoglobulins, and clotting-factor concentrates. These purified or manufactured proteins have product-specific indications, such as replacing a particular missing protein or factor. They are distinct from transfusable components and have their own prescribing and handling instructions.
Storage and handling
Blood components require controlled, product-specific storage. Exact limits and expiration dates depend on the product, processing method, and blood-bank label. Never judge storage suitability by appearance or return a product to storage without following local policy.
Red blood cells: Commonly refrigerated at in the United States. Use a designated, monitored blood-storage refrigerator, not an ordinary ward refrigerator.
: Usually stored at with gentle, continuous agitation. Room-temperature storage can support bacterial growth, so follow the labeled expiration and product-specific bacterial-risk controls. Some approved products have different storage conditions or dating.
Frozen and : Keep frozen at the temperature specified for the product. After thawing, storage time and temperature are limited and product-specific. Do not refreeze unless the label and procedure explicitly permit it.
Request components when needed, begin transfusion promptly after issue, and follow the product label and facility policy for completion time. If a component is delayed, returned, or exposed to uncertain conditions, contact the transfusion service rather than independently deciding that it is safe to use.
Checks before and during administration
Before administration, confirm the order and clinical indication, consent or the documented decision process, and any required special product attributes. Consider alternatives where appropriate.
Protect both patient and specimen identity by following the facility's identification and blood-sample collection procedure. At the bedside, perform the required check with the patient and product. Match identifiers, component, compatibility information, expiration, and special requirements; stop and resolve any discrepancy before starting.
Use approved transfusion equipment and follow local procedures. Record baseline observations and observe the patient closely, especially at the start. Complete further monitoring and documentation as required by policy, and tell patients to report new symptoms immediately.
Recognize and respond to a reaction
New fever or chills, rash, breathing difficulty, pain, hypotension, or sudden distress during transfusion warrants immediate attention. Treat these symptoms as a .
Stop the transfusion, assess the patient, and call for clinical help. Maintain IV access as directed by protocol, notify the transfusion service, and follow the facility's reaction work-up and reporting procedure. Do not restart the component unless the patient has been evaluated and restart is authorized under policy.
Record product identification, start and stop times, observations, the patient's response, and actions taken. Return or retain the bag and tubing as directed by the reaction protocol; do not discard them before consulting the required procedure.
