Epiglottitis (eh-pih-glah-TIE-tis) is a condition involving life-threatening swelling of the epiglottis. It is usually caused by a bacterial infection of the epiglottis and can result in a blockage of the trachea (windpipe) and severe breathing difficulty.

What Is Epiglottitis?

Epiglottitis, also known as supraglottitis (su-pra-glah-TIE-tis), is characterized by inflammation and swelling of the epiglottis and other upper airway structures. The epiglottis can become dangerously swollen within just a few hours, leading to narrowing of the airway and severe breathing difficulty.

Epiglottitis is usually caused by bacterial infection. Haemophilus influenzae type B (Hib) bacteria accounted for the majority of epiglottitis cases before the widespread use of the Hib vaccine. Staphylococcus aureus Streptococcus pneumoniae and group A, B, and C streptococci bacteria; certain viruses; traumatic injuries; scalding; and severe smoke inhalation (causing burns in the upper airway) can also lead to epiglottitis.

Who Gets Epiglottitis?

Epiglottitis is most common in children under 7 years of age. In the United States, cases of epiglottitis have declined greatly since the Hib vaccine was introduced in 1985.

* epiglottis (eh-pih-GLAH-tis) is a soft flap of tissue that covers the opening of the trachea (windpipe) when a person swallows to prevent food or fluid from entering the airway and lungs.

Epiglottitis itself is not contagious, but the bacterial infections that can lead to the condition are. This means the bacteria can spread through

Bacterial infection may cause inflammation and swelling of the epiglottis, which can quickly bring about narrowing or even closing of the airway and severe breathing problems.

person-to-person contact, often in drops of moisture from the respiratory tract when someone sneezes, coughs, or breathes.

What Are the Signs and Symptoms of Epiglottitis?

Epiglottitis often begins with a sore throat. Symptoms may come on suddenly and include:

  • high fever
  • inability to swallow and drooling
  • difficulty breathing
  • muffled voice
  • stridor (STRY-dor, a high-pitched, squeaking noise that occurs while breathing in; it is present usually only if there is narrowing or blockage of the upper airway)
  • a "sniffing" posture (when a young child leans forward, with chin extended, to make it easier to breathe)

Because their airways are smaller than those of adults, children with epiglottitis are at higher risk for developing severe breathing problems.

How Do Doctors Diagnose and Treat Epiglottitis?

Epiglottitis is a medical emergency that must be treated in a hospital. Ensuring that the person is able to breathe is the first and most important concern. Often a procedure called intubation (in-too-BAY-shun) is

Normal airways allow the free flow of air through the nose and mouth past the epiglottis, and then into the lungs.

performed, in which a tube is inserted into the windpipe through the mouth or nose to ensure that air can continue to flow into the lungs. In some cases, an emergency tracheostomy * must be performed to bypass the blocked part of the person's airway.

Doctors usually diagnose epiglottitis based on a physical examination and the patient's medical history. If the diagnosis is not clear, a doctor may order an X ray of the neck that will show if the epiglottis is swollen. Blood cultures or other blood tests may be used to confirm that the person has a bacterial or viral infection.

Intravenous * (IV) antibiotics are usually given to combat the infection that led to epiglottitis. Corticosteroid * medication is sometimes given to further reduce the swelling of the upper airway so the person can breathe more easily.

How Long Does It Take to Recover
from Epiglottitis?

People with epiglottitis are hospitalized, usually in intensive care, for several days to a week or more to manage the infection that led to epiglottitis. The time it takes to fully recover varies depending on the particular infection.

* tracheostomy (tray-kee-AHS-tuh-me) refers to a small opening through the neck into the trachea, or windpipe, which has been made to allow air to enter the lungs more directly. The surgical procedure to create a tracheostomy is usually performed when a person's upper airway is narrowed or blocked or when there are other problems causing breathing difficulty.

* intravenous (in-tra-VEE-nus) (IV) means within or through a vein. For example, medications, fluid, or other substances can be given through a needle or soft tube inserted through the skin's surface directly into a vein.

Possible complications of epiglottitis include pneumonia * , ear infection and, rarely, meningitis * or bacteremia * caused by the same microorganism that caused the epiglottitis.

If not treated quickly, epiglottitis can result in complete airway obstruction (air can no longer flow into the lungs) and death.

Can Epiglottitis Be Prevented?

The best way to prevent epiglottitis is to avoid infection by the bacteria that most commonly cause it. The Hib vaccine, which is part of the routine childhood immunization schedule in the United States, has been extremely successful in decreasing the number of cases of epiglottitis resulting from H. influenzae infection. The Hib vaccine is given as four separate injections (shots) before 2 years of age.

* corticosterolds (kor-tih-ko-STIR-oyds) are chemical substances made by the adrenal glands that have several functions in the body, including maintaining blood pressure during stress and controlling inflammation. They can also be given to people as medication to treat certain illnesses.

* pneumonia (nu-MO-nyah) is inflammation of the lung.

* meningitis (meh-nin-JY-tis) is an inflammation of the meninges, the membranes that surround the brain and the spinal cord, Meningitis is most often caused by infection with a virus or a bacterium.

* bacteremia (bak-tuh-REE-me-uh) is the presence of bacteria in the blood.
