Epiglottitis: Symptoms, Causes, and Emergency Care in the UK

Epiglottitis is a potentially life-threatening condition characterised by the inflammation and swelling of the epiglottis. The epiglottis is a small, leaf-shaped flap of cartilage located at the base of the tongue. Its vital function is to prevent food and liquid from entering the trachea (windpipe) during swallowing. When this tissue becomes infected or injured, it can swell rapidly, potentially blocking the airway and preventing oxygen from reaching the lungs.

In the United Kingdom, the incidence of epiglottitis has significantly declined since the introduction of the Haemophilus influenzae type b (Hib) vaccine in the early 1990s. However, it still occurs in both children and adults, often caused by other bacteria, viruses, or physical trauma to the throat. Because of the risk of sudden airway closure, any suspicion of this condition is treated as a clinical emergency by the NHS.

The symptoms of epiglottitis usually develop quickly and worsen over a matter of hours. Patients often present with what feels like a rapidly progressing sore throat, but the pain is typically out of proportion to what can be seen during a simple visual inspection of the mouth.

Key Symptoms in Adults and Children:

• Severe sore throat: A sudden and intense pain that makes talking or swallowing difficult.
• Dysphagia: Significant difficulty or pain when swallowing.
• Drooling: Because swallowing is so painful, patients may allow saliva to pool and drip from the mouth.
• High temperature: A fever often exceeding 38°C, often accompanied by chills.
• Change in voice: The voice may sound muffled, often described as a 'hot potato voice'.
• Stridor: A high-pitched, rasping sound when breathing in, indicating a partially blocked airway.

Patients may also adopt a 'tripod position'—sitting upright, leaning forward with their hands on their knees, and poking their chin out to help open the airway.

While Haemophilus influenzae type b was once the primary cause, the successful UK vaccination programme means other triggers are now more common. According to NICE (National Institute for Health and Care Excellence) guidelines, healthcare providers must consider a range of pathogens and external factors.

• Bacterial Infections: Other strains of Streptococcus (including those that cause strep throat) and Staphylococcus aureus can infect the epiglottis.
• Viral Infections: Viruses such as the varicella-zoster virus (shingles/chickenpox) or respiratory viruses can occasionally lead to secondary swelling.
• Physical Injury: Swallowing very hot liquids or chemicals can burn the throat and cause reactive swelling.
• Smoking: Inhalation of illicit substances or even heavy tobacco use can irritate the upper airway tissues.

If you are experiencing a standard sore throat with a cough and no difficulty breathing, you may wish to speak to a GP online for advice on symptom management or to exclude common conditions like pharyngitis or tonsillitis. An online doctor UK service can provide a calm assessment of your symptoms and advise on whether your condition requires routine care or urgent escalation.

However, it is critical to understand the boundary between a routine infection and a medical emergency. If you or your child have a high fever and are struggling to swallow even your own saliva, or if your voice has become significantly muffled, you should not wait for a routine appointment. Our clinical team at OnlineDoctor24 prioritises patient safety; if we suspect a compromised airway during a video consultation, we will immediately advise you to contact emergency services.

In an NHS hospital setting, the priority is always airway stabilisation. Doctors will avoid agitating the patient, as crying or stress can cause the airway to close completely. Diagnosis is often confirmed via a fibre-optic laryngoscopy, where a thin tube with a camera is used to view the epiglottis safely.

Treatment usually involves:

• Airway Management: This may include oxygen therapy or, in severe cases, intubation (placing a tube in the windpipe) to ensure the patient can breathe.
• Intravenous Antibiotics: To treat the underlying bacterial infection rapidly.
• Steroids: Medication to reduce the inflammation and swelling of the throat tissues.
• Monitoring: Patients are typically kept in an Intensive Care Unit (ICU) or a high-dependency ward until the swelling subsides and the danger has passed.

The best way to prevent the most dangerous form of epiglottitis is to ensure that children remain up to date with their NHS vaccination schedule. The Hib vaccine is usually given as part of the '6-in-1' vaccine at 8, 12, and 16 weeks of age, with a booster at one year. While this does not prevent all cases of epiglottitis (as other bacteria can cause it), it provides robust protection against the most aggressive strain. Maintaining good hand hygiene and avoiding close contact with people who have severe respiratory infections can also reduce the risk of bacterial transmission.
