A patient in the trauma unit requires emergency release of Fresh Frozen Plasma (FFP). His blood donor card states he is group AB, Rh-positive. Which blood group of FFP should be issued?

When determining the appropriate blood group for Fresh Frozen Plasma (FFP) for a patient, it is essential to consider the donor blood type and the universal compatibility of plasma products. In the case of a patient with an AB blood type, they are able to receive plasma from any blood group without the risk of transfusion reactions. This is because individuals with AB blood type do not have anti-A or anti-B antibodies in their plasma.

When issuing FFP for a patient who is AB, it is ideal to provide AB plasma if it is available, as this will ensure the most efficient match and minimizes the introduction of foreign antibodies. Therefore, issuing FFP from a donor with AB blood type is the best choice for this patient's needs.

Other blood types, while they can theoretically be used to some extent, may introduce unnecessary risks or complications. For example, Type O plasma is often considered the universal donor for red blood cells but is not the ideal choice for plasma when AB plasma is available. Utilizing the most compatible plasma, such as AB, maximizes safety and effectiveness in transfusion therapy. This reflects standard practice in blood bank operations.
