Acute Epiglottitis

Symptoms

Common signs and symptoms of Acute Epiglottitis include:

Severe sore throat that develops rapidly

Muffled or hoarse voice, often described as 'hot potato voice'

High fever, typically above 101°F (38.3°C)

Difficulty and pain when swallowing

Excessive drooling due to inability to swallow saliva

Breathing difficulties with stridor (high-pitched breathing sound)

Preference for sitting upright and leaning forward

Restlessness and anxiety due to breathing trouble

Rapid heart rate

Skin turning blue around lips or fingernails

Feeling like something is stuck in the throat

Chills and general feeling of being very unwell

When to see a doctor

If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.

Causes & Risk Factors

Several factors can contribute to Acute Epiglottitis.

Acute epiglottitis occurs when the epiglottis becomes infected and inflamed, usually due to bacterial or viral invasion.

Acute epiglottitis occurs when the epiglottis becomes infected and inflamed, usually due to bacterial or viral invasion. The most common culprit historically was Haemophilus influenzae type b (Hib), but widespread vaccination has dramatically reduced these cases. Today, other bacteria like Streptococcus pneumoniae, Staphylococcus aureus, and Streptococcus pyogenes are more frequent causes, especially in adults.

Viruses can also trigger epiglottitis, including those that cause common colds, flu, chickenpox, and respiratory syncytial virus (RSV).

Viruses can also trigger epiglottitis, including those that cause common colds, flu, chickenpox, and respiratory syncytial virus (RSV). Sometimes fungi, particularly in people with weakened immune systems, can cause the infection. The inflammation process works like this: when harmful microorganisms invade the epiglottis tissue, the body's immune system responds by sending white blood cells to fight the infection, causing swelling and inflammation.

Non-infectious causes can also lead to epiglottitis, though less commonly.

Non-infectious causes can also lead to epiglottitis, though less commonly. These include direct injury to the throat from hot liquids, chemical burns from inhaling harsh substances, or physical trauma from medical procedures. Smoking crack cocaine has been linked to epiglottitis in some cases. Rarely, severe allergic reactions can cause similar swelling, though this typically affects multiple throat structures, not just the epiglottis.

Risk Factors

Lack of Haemophilus influenzae type b (Hib) vaccination
Age between 2-6 years or over 85 years
Male gender
Weakened immune system from illness or medications
Living in crowded conditions or institutional settings
Recent upper respiratory tract infection
History of frequent throat infections
Exposure to tobacco smoke or air pollution
Certain chronic conditions like diabetes or kidney disease
Use of immunosuppressive medications or chemotherapy

Diagnosis

How healthcare professionals diagnose Acute Epiglottitis:

1
Diagnosing acute epiglottitis requires immediate medical evaluation, often in an emergency room setting.
Diagnosing acute epiglottitis requires immediate medical evaluation, often in an emergency room setting. The doctor will first assess breathing and overall stability, as this condition can worsen rapidly. They'll listen carefully to the patient's voice and breathing sounds, looking for the characteristic muffled 'hot potato' voice and high-pitched breathing sounds called stridor. The medical team will avoid examining the throat directly in children, as this can trigger complete airway obstruction.
2
Lateral neck X-rays can show the classic 'thumbprint sign' - a swollen epiglottis that looks like a thumbprint on the X-ray image.
Lateral neck X-rays can show the classic 'thumbprint sign' - a swollen epiglottis that looks like a thumbprint on the X-ray image. However, if the patient is stable, doctors may proceed directly to laryngoscopy, where a flexible camera is used to visualize the throat and confirm epiglottis swelling. This procedure is done carefully, often with airway management equipment readily available. Blood tests help identify the specific bacteria or virus causing the infection and check for signs of widespread infection.
3
Doctors must distinguish epiglottitis from other conditions that cause similar symptoms.
Doctors must distinguish epiglottitis from other conditions that cause similar symptoms. Croup typically affects younger children and causes a distinctive barking cough, while epiglottitis rarely involves coughing. Bacterial tracheitis, peritonsillar abscess, and retropharyngeal abscess can mimic epiglottitis but have different patterns on imaging. Foreign body obstruction usually has a clear history of choking or aspiration. The combination of rapid onset, high fever, drooling, and muffled voice strongly suggests epiglottitis.

Complications

The most serious complication of acute epiglottitis is complete airway obstruction, which can occur suddenly and be life-threatening.
This happens when the swollen epiglottis completely blocks the passage of air to the lungs.
Without immediate intervention, this can lead to respiratory arrest and death within minutes.
Other respiratory complications include pneumonia, which can develop if bacteria spread to the lungs, and pneumothorax (collapsed lung) if emergency airway procedures are needed.
Systemic complications can include sepsis, where the infection spreads throughout the bloodstream, and meningitis if certain bacteria like Haemophilus influenzae spread to the brain and spinal cord.
Rarely, the infection can form abscesses (pockets of pus) in surrounding throat tissues.
With prompt treatment, most people recover completely without long-term effects.
However, delays in treatment or misdiagnosis can lead to permanent complications or death, which is why epiglottitis is always considered a medical emergency requiring immediate hospitalization and expert care.

Prevention

Practicing good hand hygiene, especially during cold and flu season
Avoiding close contact with people who have respiratory infections
Not sharing eating utensils, drinks, or personal items
Maintaining up-to-date vaccinations for pneumococcus and influenza
Avoiding tobacco smoke and air pollution when possible
Managing chronic conditions like diabetes that can weaken immunity

Treatment Approaches

Treatment for acute epiglottitis always begins with securing and protecting the airway, which may require intubation (inserting a breathing tube) or even an emergency tracheostomy in severe cases.

Treatment for acute epiglottitis always begins with securing and protecting the airway, which may require intubation (inserting a breathing tube) or even an emergency tracheostomy in severe cases. This is typically done in an operating room or intensive care unit by experienced medical professionals. Once the airway is secure, patients receive intravenous antibiotics immediately, usually broad-spectrum antibiotics like ceftriaxone or cefuroxime that cover the most likely bacterial causes.

Antibiotic

Hospitalization is mandatory for epiglottitis, with patients typically staying in the ICU for close monitoring until swelling reduces.

Hospitalization is mandatory for epiglottitis, with patients typically staying in the ICU for close monitoring until swelling reduces. Corticosteroids like dexamethasone may be given to help reduce inflammation and swelling, though their effectiveness is still being studied. Supportive care includes IV fluids to prevent dehydration (since swallowing is difficult), oxygen therapy if needed, and medications to manage fever and pain. Humidified air can help soothe irritated airways.

MedicationTherapyAnti-inflammatory

Most patients show improvement within 24-48 hours of starting antibiotics, with swelling gradually decreasing.

Most patients show improvement within 24-48 hours of starting antibiotics, with swelling gradually decreasing. The breathing tube, if needed, is typically removed once the epiglottis returns to normal size, usually within 2-3 days. Complete recovery generally occurs within a week with appropriate treatment. Close contacts, especially household members, may receive prophylactic antibiotics if Haemophilus influenzae is confirmed as the cause.

Antibiotic

New research is exploring the role of different antibiotic combinations and the optimal timing of corticosteroid administration.

Some studies suggest that early corticosteroid use may reduce the need for intubation, but this remains an area of ongoing investigation. The key to successful treatment remains early recognition and immediate medical intervention.

Living With Acute Epiglottitis

Most people who recover from acute epiglottitis return to completely normal lives with no ongoing restrictions or special care requirements. During the recovery period, which typically lasts 1-2 weeks, patients should rest their voice as much as possible and stay well-hydrated. Soft, cool foods and liquids are easier to swallow during the healing process. Follow-up appointments with healthcare providers ensure complete recovery and address any lingering concerns.

For families who have experienced epiglottitis, education about recognizing early symptoms becomes crucial.For families who have experienced epiglottitis, education about recognizing early symptoms becomes crucial. Parents should know when to seek immediate medical attention and understand that epiglottitis can recur, though this is uncommon. Keeping vaccination records up-to-date and ensuring all family members receive recommended immunizations helps prevent future episodes.

The psychological impact shouldn't be overlooked, especially for children and their families.The psychological impact shouldn't be overlooked, especially for children and their families. The rapid onset and severity of symptoms, combined with emergency treatment and hospitalization, can be traumatic. Some families benefit from counseling or support groups. Most importantly, people should understand that with current medical care, epiglottitis has an excellent prognosis when treated promptly. The key is maintaining awareness of symptoms while not living in fear, since the condition remains relatively rare thanks to widespread vaccination programs.

Frequently Asked Questions

Can adults get epiglottitis or is it just a childhood disease?

Adults can definitely get epiglottitis, and it's actually more common in adults than children in countries with good Hib vaccination programs. Adult cases tend to progress more slowly than childhood cases but still require immediate medical attention.

How quickly does epiglottitis develop and worsen?

Epiglottitis typically develops rapidly, often within hours. Symptoms can progress from a sore throat to severe breathing difficulties in just 4-6 hours, which is why it's considered a medical emergency requiring immediate treatment.

Is epiglottitis contagious and can it spread to other family members?

The bacteria or viruses causing epiglottitis can be contagious, but most exposed people don't develop epiglottitis itself. Close family members may receive preventive antibiotics if certain bacteria like Haemophilus influenzae are identified as the cause.

Can someone die from epiglottitis?

While epiglottitis can be life-threatening if untreated due to airway obstruction, death is rare with prompt medical care. The mortality rate is less than 1% when patients receive appropriate treatment in a hospital setting.

Will my child need surgery if they have epiglottitis?

Most children don't need surgery. Treatment typically involves antibiotics and supportive care, though some may need a breathing tube temporarily. Emergency surgical procedures like tracheostomy are rare and only used when other airway management fails.

How long does it take to recover from epiglottitis?

Most people start feeling better within 24-48 hours of starting antibiotics, with complete recovery typically occurring within a week. Hospital stays usually last 2-4 days, depending on severity and response to treatment.

Can epiglottitis come back after someone has had it once?

Recurrent epiglottitis is uncommon but possible, especially in people with weakened immune systems. Having epiglottitis once doesn't provide immunity against future episodes, since different bacteria or viruses can cause the condition.

Should I be worried if my child has a sore throat and fever?

Most sore throats are not epiglottitis. Seek immediate medical attention if your child has severe throat pain with drooling, muffled voice, difficulty breathing, or prefers to sit upright and lean forward. Trust your instincts if something seems seriously wrong.

Are there any long-term effects after recovering from epiglottitis?

Most people recover completely with no long-term effects. Rarely, some may experience temporary voice changes that resolve over weeks to months. The vast majority return to normal activities without restrictions.

Can the Hib vaccine completely prevent epiglottitis?

The Hib vaccine prevents epiglottitis caused by Haemophilus influenzae type b, but other bacteria and viruses can still cause the condition. However, Hib vaccination has reduced childhood epiglottitis cases by over 95% in vaccinated populations.
