  1. a Release of vasoactive amines
  2. b Manifestations dependent upon drug
    Fairly predictable
    No prior exposure needed
    Dose related
    Onset may be delayed
    Common

5 Multiple Choice Questions

  1. Vanco‐ life threatening anaphylactic &
    anaphylactoid (red man syndrome) reactions
    PCN‐ most common cause of fatal anaphylaxis (structurally r/t cephalosporins-> theoretical ↑d risk of allergy
  2. Rare, accounts for 1% of adverse reactions to locals
    Ester based->PABA
    Preservatives (methylparaben, propylparaben) similar to PABA
    No proven cross-reactivity between ester & amides
  3. Cold agglutinins->activation of compliment & plts, hyper‐viscosity, renal failure
  4. Airway‐ macroglossia
    CV‐ conduction disturbance, RHF
    Renal‐ nephrotic syndrome
    Nerves‐ autonomic neuropathy, nerve compression
  5. Antigens are normally endogenous, although exogenous chemicals (haptens) which can attach to cell membranes
    Drug-induced hemolytic anemia, granulocytopenia & thrombocytopenia
    IgM & IgG mediated
    Phagocytes & K cells play a role
