NHS Acute Care for Anaphylaxis
Understanding Anaphylaxis
Anaphylaxis is a severe and life-threatening allergic reaction that can occur rapidly. It demands immediate medical attention. Common triggers include foods such as peanuts and shellfish, insect stings, medications, and latex. Recognising the early symptoms—which may include difficulty breathing, a rapid heartbeat, swelling of the throat, and a sudden rash—can be crucial for prompt treatment.
Initial Emergency Response
Immediate action is essential when dealing with anaphylaxis. The priority is to administer an adrenaline auto-injector (such as an EpiPen) as soon as symptoms appear. Adrenaline works quickly to reduce throat swelling, open the airways, and maintain blood pressure. After administering adrenaline, it’s important to call emergency services (999 in the UK) promptly and inform them of the situation. Position the person in a way that is most comfortable for them, usually sitting up if they are having trouble breathing or lying down if they feel faint or weak.
Hospital Treatment
Upon arrival at the hospital, the patient can expect to receive continued medical assessment and care. NHS practitioners may administer additional doses of adrenaline if necessary, as well as antihistamines and steroids to further reduce symptoms and prevent a recurrence. Oxygen therapy may be provided if breathing difficulties persist. Monitoring in a clinical setting is essential, as symptoms of anaphylaxis can sometimes return within hours.
Post-Acute Care
Following the acute phase of anaphylaxis, the NHS provides thorough follow-up care. This includes prescribing additional adrenaline auto-injectors and ensuring the patient is well informed on how to use them. Referral to an allergy specialist might be recommended for further tests and management strategies. Patients are often advised to wear medical identification and may receive a tailored allergy action plan to mitigate future risks.
Conclusion
Anaphylaxis is a medical emergency that requires swift and effective care. The NHS has established protocols to handle such acute allergic reactions, ensuring patients receive the immediate and follow-up care needed to manage this serious condition. Public awareness and preparedness, including knowing how to use an adrenaline auto-injector, are crucial in mitigating the risks associated with anaphylaxis.
Frequently Asked Questions
What is anaphylaxis?
Anaphylaxis, also known as anaphylactic shock, is a severe, potentially life-threatening allergic reaction that can develop rapidly.
What are common triggers of anaphylaxis?
Common triggers include foods like peanuts, tree nuts, fish, shellfish, dairy products, and eggs; insect stings; medications; and latex.
What are the symptoms of anaphylaxis?
Symptoms can include hives, swelling of the face, lips, or throat, difficulty breathing, a rapid heartbeat, dizziness, and a sharp drop in blood pressure.
How quickly can anaphylaxis occur after exposure to an allergen?
Anaphylaxis can occur within minutes of exposure to an allergen, though reactions can sometimes develop more slowly, over the course of several hours.
How is anaphylaxis diagnosed?
Anaphylaxis is primarily diagnosed based on the rapid onset of symptoms following exposure to a known allergen and through the patient's medical history.
What is the first aid treatment for anaphylaxis?
Administer an adrenaline (epinephrine) auto-injector immediately if available, call emergency services (999), lie the person down and raise their legs, and keep them calm.
What should be done after administering an adrenaline auto-injector?
Even if symptoms improve after using an adrenaline auto-injector, the person should go to the hospital for observation, as symptoms can return or worsen.
Can anaphylaxis be prevented?
Anaphylaxis can often be prevented by avoiding known allergens and carrying an adrenaline auto-injector if you have a history of severe allergies.
Is there a difference between an epinephrine auto-injector and adrenaline?
No, epinephrine and adrenaline are the same medication. The terms are used interchangeably.
Can children outgrow anaphylaxis?
Some children may outgrow certain food allergies, which are common triggers of anaphylaxis, but others may continue to have severe allergic reactions into adulthood.
What is the role of antihistamines in treating anaphylaxis?
Antihistamines may help relieve some symptoms of an allergic reaction, but they are not effective for treating the life-threatening symptoms of anaphylaxis. Adrenaline is required.
How should an adrenaline auto-injector be used?
An adrenaline auto-injector should be injected into the outer thigh, through clothing if necessary, and held in place for several seconds to ensure the medication is fully delivered.
Can multiple doses of adrenaline be necessary during an anaphylactic reaction?
Yes, a second dose of adrenaline may be necessary if symptoms do not improve after the first dose or if they return. Always seek immediate medical assistance.
Why is it important to carry an adrenaline auto-injector at all times if you're at risk for anaphylaxis?
Anaphylaxis can occur suddenly and without warning. Having an adrenaline auto-injector readily available can save your life in the event of a severe allergic reaction.
What follow-up care is recommended after an anaphylactic reaction?
After an anaphylactic reaction, it’s important to follow up with an allergist or your GP to review your treatment plan, refill your medication, and identify any potential triggers.
