Study Notes
Definition
- Anaphylaxis is a severe, potentially life-threatening allergic reaction.
Causes
- Common triggers include:
- Foods (e.g., peanuts, tree nuts, shellfish, eggs, milk)
- Medications (e.g., antibiotics, non-steroidal anti-inflammatory drugs)
- Insect stings (e.g., bees, wasps)
- Latex
- Exercise (sometimes in conjunction with food)
Symptoms
- Develop rapidly, typically within minutes to hours:
- Skin reactions: hives, itching, flushing
- Respiratory issues: difficulty breathing, wheezing, throat swelling
- Gastrointestinal symptoms: nausea, vomiting, diarrhea
- Cardiovascular problems: rapid or weak pulse, low blood pressure, fainting
- Neurological symptoms: confusion, anxiety, dizziness
Diagnosis
- Based on:
- Clinical history and symptoms
- Exposure to known allergens
Treatment
- Immediate administration of epinephrine (adrenaline) is crucial.
- Can be given via auto-injector (e.g., EpiPen)
- Additional treatments may include:
- Antihistamines (for mild reactions)
- Corticosteroids (to reduce inflammation)
- Oxygen therapy (for respiratory issues)
Prevention
- Avoid known allergens.
- Carry an epinephrine auto-injector if at risk.
- Educate self and others about recognizing anaphylaxis symptoms.
Emergency Response
- Call emergency services immediately if anaphylaxis is suspected.
- Lay the person down and elevate their legs if possible.
- Administer epinephrine as soon as available.
Prognosis
- With prompt treatment, most individuals recover completely.
- Recurrent episodes may occur; monitoring and avoiding triggers are essential.
Definition
- Anaphylaxis is a severe allergic reaction that can be life-threatening.
Causes
- Common triggers include:
- Foods: peanuts, tree nuts, shellfish, eggs, milk
- Medications: antibiotics and non-steroidal anti-inflammatory drugs
- Insect stings from bees and wasps
- Latex exposure
- Exercise, especially when combined with certain foods
Symptoms
- Symptoms can develop rapidly, often within minutes to hours:
- Skin reactions: hives, itching, and flushing
- Respiratory issues: difficulty breathing, wheezing, and swelling in the throat
- Gastrointestinal symptoms: nausea, vomiting, and diarrhea
- Cardiovascular problems: rapid or weak pulse, low blood pressure, and fainting
- Neurological symptoms: confusion, anxiety, and dizziness
Diagnosis
- Diagnosis relies on:
- Clinical history regarding past allergic reactions and symptoms
- Recent exposure to known allergens
Treatment
- Immediate administration of epinephrine (adrenaline) is crucial, typically through an auto-injector like EpiPen.
- Additional treatments may include:
- Antihistamines for managing mild reactions
- Corticosteroids to reduce inflammation
- Oxygen therapy for addressing respiratory complications
Prevention
- Avoidance of known allergens is key.
- Individuals at risk should carry an epinephrine auto-injector.
- Education about anaphylaxis symptoms is essential for self and others.
Emergency Response
- Immediate action is necessary:
- Call emergency services if anaphylaxis is suspected.
- Lay the affected person down and elevate their legs if feasible.
- Administer epinephrine as soon as possible.
Prognosis
- Most individuals recover completely with prompt treatment.
- Monitoring for recurrent episodes and avoidance of triggers is vital for ongoing safety.
