Anaphylaxis: Rapid Response to Severe Allergic Reactions

For many Canadians, the word "allergy" brings to mind minor inconveniences: sneezing from pollen or a mild rash from certain foods. However, for some, exposure to a seemingly innocuous substance can trigger a severe, life-threatening allergic reaction called anaphylaxis. This is a rapid, body-wide response that can quickly shut down vital systems, making immediate recognition and intervention absolutely critical.

At Ready 4 Everything Training and Supplies, we emphasize that knowing how to recognize anaphylaxis and administer an epinephrine auto-injector (like an EpiPen) is a life-saving skill that can dramatically alter the outcome of this emergency.

What is Anaphylaxis? A Severe, Rapid Response

Anaphylaxis is the most severe and potentially fatal type of allergic reaction. It occurs when the immune system overreacts to an allergen, releasing chemicals that cause a sudden, widespread drop in blood pressure (shock) and constriction of airways, leading to difficulty breathing. This reaction can develop within minutes of exposure to an allergen and can progress rapidly.

Common Anaphylaxis Triggers:

While a person can be allergic to anything, some common triggers include:

• Foods: Peanuts, tree nuts, shellfish, fish, milk, eggs, soy, wheat, sesame.

• Insect Stings: Bees, wasps, hornets, fire ants.

• Medications: Antibiotics (e.g., penicillin), NSAIDs (e.g., ibuprofen), aspirin.

• Latex: Rubber products.

• Exercise-induced anaphylaxis: Rare, but can occur after exercise.

Recognizing the Signs and Symptoms: A Multi-System Attack

Anaphylaxis can affect multiple body systems simultaneously. Look for a combination of these signs, or a rapid worsening of symptoms:

1. Skin Reactions (often first, but not always present):

• Hives (red, itchy welts)

• Flushing (redness)

• Itching or tingling sensation, especially on the face, lips, and tongue

• Swelling of the face, lips, tongue, throat, or other body parts (angioedema)

2. Breathing Problems (most dangerous):

• Shortness of breath, wheezing, or difficulty breathing

• Tightness in the chest or throat

• Hoarse voice, difficulty swallowing

• Stridor (a high-pitched crowing sound when breathing in)

3. Circulatory Problems (leading to shock):

• Pale, cool, clammy skin

• Weak, rapid pulse

• Dizziness or lightheadedness

• Fainting or loss of consciousness

• Sudden drop in blood pressure

4. Digestive Symptoms:

• Nausea, vomiting, diarrhea

• Abdominal pain or cramping

5. Other Symptoms:

• Feeling of impending doom

• Anxiety

What to Do: Immediate Action – Epinephrine is Key!

Your immediate actions can save a life when anaphylaxis strikes:

1. Call 911 Immediately: This is critical. State clearly that the person is having a severe allergic reaction (anaphylaxis) and you need an ambulance.

2. Administer Epinephrine: If the person has a prescribed epinephrine auto-injector (e.g., EpiPen, Allerject) and is showing signs of anaphylaxis, help them administer it immediately. Do NOT wait. Epinephrine is the only medication that can stop anaphylaxis.

• How to Use an Auto-Injector (General Steps - always follow specific device instructions):

• Remove the safety cap.

• Press the orange tip (or black tip for Allerject) firmly against the outer mid-thigh, holding it in place for 3-10 seconds (as per device instructions). It can be given through clothing.

• Remove the auto-injector. Massage the injection site for 10 seconds.

• If you are unsure, err on the side of caution and administer the epinephrine. There is little harm in giving epinephrine if it's not needed, but great harm in delaying it if it is needed.

3. Position the Person:

• If conscious and breathing adequately, help them sit in a comfortable position, or lie them down with legs elevated if they are feeling faint or showing signs of shock.

• If they are unresponsive or vomiting, place them in the recovery position (on their side).

4. Monitor A-B-Cs: Continuously monitor their level of consciousness, breathing, and pulse. Be prepared to start CPR if they become unresponsive and stop breathing normally.

5. Second Dose (if needed): If symptoms do not improve within 5-15 minutes (follow specific guidelines), a second dose of epinephrine may be given using a new auto-injector.

6. Reassure the Person: Keep them calm and informed that help is on the way.

Prevention is Best: Education and Awareness

While knowing how to respond is vital, preventing anaphylaxis is equally important. This includes:

• Careful reading of food labels.

• Avoiding known allergens.

• Carrying an auto-injector at all times if prescribed.

• Educating friends, family, and colleagues about allergies and emergency plans.
