Epiglottitis is a potentially life-threatening condition that results in inflammation of the epiglottis. This can block the flow of air into the lungs, making it difficult for breathing to occur.
In this article, we will provide an overview of epiglottitis, including its causes, symptoms, and treatment options.

What is Epiglottitis?
Epiglottitis is an acute upper airway infection that causes severe supraglottic swelling. It causes inflammation of the epiglottis, which is a small flap of tissue that covers the trachea.
When this type of swelling occurs, it can block the airway and make it difficult for the patient to move air in and out of the lungs.
This condition is often life-threatening and should be treated as an emergency by medical professionals. The patient will likely require immediate intubation and breathing support from a mechanical ventilator.
Epiglottitis is usually caused by a bacterial infection, such as Haemophilus influenzae type b (Hib). However, it can also be caused by viruses, such as the Epstein-Barr virus (EBV), or by other factors, such as irritants.
Other bacterial infections that can cause epiglottitis include pneumococcus, staphylococcus aureus, and streptococcus pneumoniae.
Signs and Symptoms
The most common signs and symptoms of epiglottitis include the following:
- Rapid onset
- Respiratory distress
- Difficulty swallowing
- Altered voice
- Sore Throat
As the swelling of the upper airway increases, airflow through the trachea is blocked. This makes it difficult for gas exchange to occur, which can have life-threatening effects.
The goal of treatment for epiglottitis is to reduce the inflammation and swelling of the epiglottis. This can be done through a variety of methods, including the following:
- Intravenous fluids
- Humidified oxygen
- Mechanical ventilation
- Surgical procedures
In severe cases, surgical procedures such as a tracheostomy or cricothyroidotomy may be indicated. A tracheostomy is a procedure in which a small incision is made in the neck and a tube is inserted into the trachea.
A cricothyroidotomy is a procedure in which an incision is made in the thyroid cartilage to gain access to the trachea. This serves as a last resort when other methods of treatment have failed due to a complete airway obstruction.
Epiglottitis Practice Questions:
1. What is epiglottitis?
It is an infection of the epiglottis and is a medical emergency. It can be caused by a virus or bacteria. It is most common in children aged 2-7. A key to remember this condition is that the swelling is ABOVE the glottis. Croup, on the other hand, shows swelling BELOW the glottis. That is how you know the difference between the two.
2. What vaccine has helped decrease the incidence of epiglottitis in children?
HiB (haemophilus influenzae type b).
3. What is the clinical presentation of epiglottitis?
Sudden onset of fever, respiratory distress, severe dysphagia, drooling, muffled voice, mild stridor with little or no coughing and tripoding.
4. What are the diagnostic studies for epiglottitis?
Direct visualization with caution because it may be fatal in children, CBC and blood cultures, and a lateral neck x-ray.
5. What is the classic x-ray finding with epiglottitis?
There will be a thumbprint sign in the epiglottis. This is one of the keys to remembering this condition. Croup, on the other hand, will show a steeple sign.

6. How can you manage epiglottitis?
As a Respiratory Therapy, our main job will be to secure the airway.
7. How do you differentiate croup from epiglottitis?
Lateral neck film.

The shape of their epiglottis is more omega-shaped than the adult “u” shape.
9. What are the signs and symptoms of epiglottitis?
There will be a sudden onset of inflammation somewhere along the glottis. There is obstruction of the airway and that leads to distal mucus plugging and respiratory distress. The child will be drooling, may have loss of voice, and will immediately go to the tripod position to try to ease their breathing.
10. What are the most common causes of epiglottitis?
The most common cause is bacterial. Bacterial includes non-typical which are
11. Why is it important to not want to examine the throat of patients that have epiglottitis?
Patients already feel the AIR RAID symptoms, so sticking something down their throat may cause even more anxiety. The patient must be relaxed. Do not use a tongue blade and do not give anything to drink.
12. What airway sound will you hear on patients with epiglottitis?
Stridor (upper respiratory sound that leads to airway obstruction).

15. What will the throat of an epiglottitis patient look like?
Swollen and cherry red.

When there is no emergency and to exclude foreign bodies.
29. What is the number one main focus of treatment for epiglottitis?
Maintain the airway.
30. What is the other treatment of epiglottitis?
Empiric therapy with coverage of the most common causes (including MRSA).
31. What are some clinical signs can be seen in children with epiglottitis?
Tripod posture (trunk leaning forward, neck hyperextended, chin forward), anxious, prefers to sit, sniffling position to maximize patency of airway, fever, respiratory distress, dysphagia, and drooling.
32. What would the epiglottis look like in epiglottitis?
Inflamed, swollen, cherry-red, tissue can block the airway, erythematous, and edematous.
33. What types of pathogens can cause epiglottitis?
Bacterial, viral and fungal. In children, usually caused by bacteria H influenza type B. In adults, due to other bacteria like Strep pneumonia or viruses such as herpes simplex or varicella-zoster
H. Influenza type B is the most common cause overall, even in immunized children and adults.

39. What is the most common presentation of epiglottitis in adults?
A sore throat.
40. How does epiglottis present?
Child looks toxic and swallowing is difficult. High fever, sore throat, dyspnea, rapidly progressive respiratory obstruction and tripoding. Drooling is usually present and the neck is hyperextended. The degree of respiratory distress varies. Note that the respiratory distress may be absent initially or it can be the first manifestation. Stridor is a late finding and suggests almost complete airway obstruction. Call for help.

43. Why may the neck be hyperextended in a child with epiglottitis?
This is an attempt to maintain the airway.
44. How do you diagnose epiglottitis?
Doing a laryngoscopy under controlled circumstances (OT or ICU) – you should see a large cherry red and swollen epiglottitis. Sometimes the aryepiglottic folds are more involved than the epiglottis. Call for help!
45. What is the outline of the management of epiglottitis based on the stability of the airway?
If they are unstable, that is, unreactive, cyanotic and bradycardic, then intubate right away. If they are stable with a high suspicion then take to OT for laryngoscopy and intubate under GA. If they are stable with moderate to low suspicion, obtain a lateral neck x-ray.
Did someone say, "5 of PEEP?" I think so! Order your own PEEP t-shirt today.
46. When do you do a laryngoscopy if the diagnosis of epiglottitis is certain or probable based on clinical findings?
Immediately but in a controlled environment. Other procedures like IVA should be avoided until the airway is
47. Do you intubate a patient with probable epiglottitis first?
No, get a lateral neck x-ray to confirm.

Epiglottitis is a potentially life-threatening condition that requires immediate medical attention. It results in swelling of the upper airway, which can block the flow of air into the lungs.
The most common signs and symptoms include respiratory distress, difficulty swallowing, altered voice, and fever. Early diagnosis and treatment are essential for the best possible outcome.
