    Transfusion question....(open not closed)

    Advertisements



    Immediately after infusing one unit of blood the patient develops a dramatic wheeze and points to his neck in distress. You notice also a general new onset of "redness".

    Question- what is your next step
    for extra brownie points discuss this event and underlying possibilities.

    Give epinephrine to counter the anaphylactic reaction witnessed.

    Mechanism:
    IgA deficiency..........

    For brownie points- before doing what test should you always test for IgA deficiency otherwise your test is irrelevant?
