nursing interventions r/t anaphylaxis
Give this one a try later!
, Be Prepared to:
•Recognize signs and symptoms of anaphylactic shock (fig 13.7 pg195)
•Maintain a patient airway
•Administer medications as appropriate
•EpiPen or Twinject •
Assess respiratory function; establish airway
•CPR (if needed)
•Epinephrine concentration 1:1000 0.3ml - 0.5ml may be repeated every 5-15
minutes
•Antihistamines (for angioedema and urticaria)
•Oxygen- 90 to 100%
•Treat bronchospasm -Nebulizer inhaled beta-adrenergic agonist
•IV fluids, isotonic solutions ie. LR, or NS
antihistamine: diphenhydramine

, Benadryl
1. Histamine-1 receptor antagonists
• Used for: S/S of type 1 hypersensitivity (allergic rhinitis, allergic
conjunctivitis, urticaria, angioedema)
indication: Allergic reaction, insomnia, cough, motion sickness,
Parkinsonism
• MOA: drug competes with histamine for the H1 effector cell sites (these
cells cause S/S of allergic reaction) = blocks histamine from its effects.
The drug does not displace the histamine that's already bound to receptors
• The following are the effects of blocking H1 receptor sites:
o Blocking action of histamine on small blood vessels
o Decreasing arteriole dilation and tissue engorgement
o Reducing leakage of plasma proteins + fluids out of the capillaries = less
edema
o Inhibiting smooth-muscle responses to histamine (blocking the
constriction of bronchial, GI, and vascular smooth muscle)
o Acting on the terminal nerve endings in the skin that flare/itch = relief of
symptoms
• Side effects: dizziness, fatigue, muscle weakness, N/V/D/C, arrhythmias
Nursing considerations: Contraindicated in lower respiratory disease (e.g.
asthma), neonates, and nursing women. May impair ability to drive.
