Study Notes
Chapter 21: Allergic Reactions
- Allergic reactions are exaggerated immune responses to substances contacting the body
- A severe allergic reaction is called anaphylaxis or an anaphylactic reaction
- Allergens are substances commonly causing allergic reactions (e.g., insect bites/stings, foods, plants, medications)
- Causes of allergic reactions include foods, insect bites, medications, and plants
- Signs and symptoms of allergic reactions may include warm tingling feelings in the face, mouth, chest, feet, hands, itching, hives, red skin, swelling of face, neck, hands, feet and/or tongue
- Respiratory system symptoms include patient feeling tightness in the throat/chest, cough, rapid breathing, labored breathing, noisy breathing, hoarseness, stridor, wheezing
- Cardiac symptoms include increased heart rate, and decreased blood pressure
- Generalized findings of allergic reactions include itchy, watery eyes, headache, a sense of impending doom, runny nose, decreasing mental status
- Assessment findings revealing shock (hypoperfusion) and severe respiratory distress suggest a severe allergic reaction
Emergency Care for Patients with Allergic Reactions
- Perform initial assessment
- Perform focused history and physical exam (history of allergies, what patient was exposed to, how they were exposed, effects, progression, interventions)
- Assess baseline vital signs and SAMPLE history
- If patient has prescribed preloaded epinephrine, administer it
- If no preloaded epinephrine is available and patient has no epinephrine auto-injector, transport immediately
Epinephrine
- A medication used to dilate bronchioles, prevent tissue swelling, constrict blood vessels, and increase heart's ability to pump blood
- Auto-injector: a device administering a preset dose of medication via intramuscular self-injection
- Indications include assessment revealing patient with a severe allergic reaction, respiratory compromise and/or hypoperfusion.
- Contraindications are none in emergency situations
- Actions of epinephrine: Dilates the bronchioles, constricts blood vessels
- Dosage: Adult – one adult auto-injector (0.3 mg); Infant and child – one infant/child auto-injector (0.15 mg)
- Side effects may include increases heart rate, pallor, dizziness, chest pain, headache, nausea, vomiting, excitability, anxiousness
Use of the Auto-Injector
- Steps are shown in the slides.
Emergency Care of Allergic Reaction
- If patient does not have signs of respiratory distress or shock (hypoperfusion), continue focused assessment
- If patient does not have wheezing or without signs of respiratory distress or shock (hypoperfusion), administer high-flow oxygen and transport
