Anaphylactic Shock Flashcards
Patho
Severe systemic hypersensitivity reaction to a specific antigen
Allergic reaction results in histamine secretion & severe widespread vasodilation.
Affects Pulmonary, Circulatory & Integumentary Systems
Results in: Systemic vasodilation causing
Smooth muscle contraction (airway)
Triggers
Seafood and Antibiotics
Smooth muscle contraction causes
Circulatory collapse
Airway compromise: R/T smooth muscle contraction
Bronchoconstriction: R/T smooth muscle contraction
Increased mucus production
Result: Respiratory Insufficiency
What is different about anaphylactic shock
Causes smooth muscle contraction (airway)
Onset
Sudden with rapid progression
Systems Affected
Pulmonary
Circulatory
Pulmonary symptoms
Laryngeal edema
Shortness of breath
Tachypnea
Wheezing
Stridor
Cyanosis
Cough, Rhonchi
Nasal congestion
Angioedema
Circulatory symptoms
Tachycardia
Hypotension
Weak pulses
Cool, pale, clammy skin AND Flushing, red raised rash, or angioedema
Syncope
Lightheaded
Arrythmias
What causes cool, pale, clammy skin
decreased CO
How can skin issues be resolved in anaphylactic shock?
antihistamines or epi
Most concerning s/s
pulmonary related
What is the cause of pulmonary symptoms
contraction of the smooth muscles in the airways
Integumentary Effects
Tingling
Warmth
Diffuse redness, flushing.
Urticaria
Pruritus
Angioedema
Swelling around the eyes
Cool, clammy skin R/T decreased CO
Urticaria
itchy red raised rash.
Causes
Blood products
