Anaphylaxis in Children

Overview

Anaphylaxis is a severe, life-threatening allergic reaction that happens quickly and can affect multiple systems in the body, including breathing, circulation, and digestion. It requires immediate medical attention. Anaphylaxis can be triggered by various allergens, such as certain foods, medications, insect stings, or latex. If not treated promptly, it can lead to serious complications, but with quick intervention, most children make a full recovery.

Symptoms

Anaphylaxis can develop within minutes of exposure to an allergen, and common symptoms include:

  • Breathing difficulties: Wheezing, shortness of breath, or swelling in the throat
  • Skin reactions: Hives, itching, or swelling, usually around the face or throat
  • Low blood pressure: Dizziness, fainting, or feeling weak
  • Gastrointestinal issues: Nausea, vomiting, stomach cramps, or diarrhoea
  • Rapid heartbeat: A fast or irregular pulse
  • Anxiety or confusion: Due to lack of oxygen or the body’s response to the allergen
  • Anaphylactic shock: A severe drop in blood pressure that can lead to unconsciousness

Causes

Anaphylaxis can be triggered by several allergens, and common causes include:

  • Food allergies: Foods like peanuts, tree nuts, shellfish, eggs, and milk are frequent triggers.
  • Medications: Antibiotics, pain relievers like aspirin or ibuprofen, and certain vaccines.
  • Insect stings: Bee, wasp, or hornet stings can cause anaphylaxis in some children.
  • Latex: Found in some medical gloves and other products.
  • Exercise-induced anaphylaxis: Although rare, strenuous physical activity can trigger anaphylaxis, especially after eating certain foods.

Diagnosis

If a child experiences anaphylaxis, doctors will diagnose it based on:

  • Medical history: Understanding what the child was exposed to before the reaction.
  • Physical exam: Checking for telltale signs like swelling, hives, or breathing problems.
  • Allergy testing: Skin or blood tests can help determine specific allergens that may have caused the reaction.
  • Emergency response: Anaphylaxis is usually diagnosed in an emergency setting based on symptoms, and immediate treatment is prioritized.

Treatment Options

Anaphylaxis is a medical emergency that requires urgent care. At Gertrude’s Children’s Hospital, our treatment protocol includes:

  • Epinephrine injection: The first and most important treatment for anaphylaxis. Epinephrine quickly reverses the severe allergic reaction by relaxing the airway muscles and improving blood pressure.
  • Oxygen therapy: For children struggling to breathe, oxygen may be given to improve oxygen levels in the blood.
  • Intravenous fluids: These are administered to raise low blood pressure.
  • Antihistamines and steroids: Used after epinephrine to manage remaining symptoms like swelling and hives.
  • Monitoring and support: Children are often monitored in the hospital for several hours after the reaction to ensure it doesn’t return.

Anaphylaxis in Children

Anaphylaxis usually comes on quickly, with symptoms like trouble breathing, swelling, hives, and a drop in blood pressure. If you suspect anaphylaxis, use an epinephrine auto-injector immediately and seek emergency care.

If your child shows signs of anaphylaxis, use an epinephrine auto-injector right away, call for emergency medical help, and take your child to the nearest hospital.

Yes, children who have had anaphylaxis are at risk of having it again if they are exposed to the allergen. It’s important to avoid known triggers and have an epinephrine auto-injector on hand at all times.

The best prevention is avoiding known allergens and having an action plan in place. Work with your child’s doctor to identify triggers and make sure your child has an epinephrine auto-injector with them at all times.
