Anaphylaxis is a severe, life-threatening allergic reaction that requires immediate medical attention. One of the most critical treatments for anaphylaxis is the administration of adrenaline, also known as epinephrine. In this guide, we will discuss the correct adrenaline dose for anaphylaxis, as well as provide an overview of the emergency treatment protocol.
Understanding Anaphylaxis
Anaphylaxis is a rapid, systemic allergic reaction that can occur within minutes of exposure to an allergen. The symptoms of anaphylaxis can vary, but common signs include hives or itching, swelling of the face, lips, tongue, or throat, difficulty breathing, abdominal cramps, nausea and vomiting, and a feeling of impending doom. If left untreated, anaphylaxis can lead to cardiac arrest, respiratory failure, and even death.
Adrenaline Dose for Anaphylaxis
The recommended adrenaline dose for anaphylaxis is 0.3 to 0.5 milligrams (mg) per dose, administered intramuscularly (IM) in the mid-outer aspect of the thigh. This dose can be repeated every 5 to 15 minutes as needed, up to a maximum of 3 doses. It is essential to note that the adrenaline dose may vary depending on the patient’s age, weight, and medical history.
| Age Group | Adrenaline Dose |
|---|---|
| Adults and children over 30 kg | 0.3 to 0.5 mg IM |
| Children between 15 kg and 30 kg | 0.15 to 0.3 mg IM |
| Children under 15 kg | 0.01 mg/kg IM (up to a maximum of 0.3 mg) |
Treatment Protocol for Anaphylaxis
The treatment protocol for anaphylaxis involves a combination of adrenaline administration, cardiovascular support, and respiratory care. The following steps should be taken:
- Call emergency services immediately
- Administer adrenaline according to the recommended dose
- Provide oxygen therapy if available
- Monitor the patient's vital signs, including blood pressure, pulse, and respiratory rate
- Establish an intravenous line for fluid administration and medication
- Transport the patient to a hospital for further treatment and observation
Prevention and Preparedness
Prevention and preparedness are key to managing anaphylaxis. Individuals with a history of allergies should:
- CARRY an EpiPen or other auto-injector with them at all times
- WEAR a medical alert bracelet or necklace
- INFORM friends, family, and coworkers about their allergy and emergency protocol
- AVOID exposure to known allergens
