The epiglottis is a piece of stiff, yet flexible tissue (called cartilage) at the back of the tongue. It closes your windpipe (trachea) when you swallow so food does not enter your airways. This helps prevent coughing or choking after swallowing.
Swelling of the epiglottis is usually caused by the bacteria Haemophilus influenzae (H. influenzae). It may also be caused by other bacteria or viruses related to upper respiratory infections.
Epiglottitis is now very uncommon, because the H. influenzae type B (Hib) vaccine is a routine childhood immunization. The disease was once most often seen in children ages 2 - 6. Rarely, epiglottitis can occur in adults.
Epiglottitis begins with a high fever and sore throat. Other symptoms may include:
Anti-inflammatory medicines called corticosteroids to decrease throat swelling
Fluids given through a vein (by IV)
Epiglottitis can be a life-threatening emergency. However, with proper treatment, the outcome is usually good.
Spasm may cause the airways to close abruptly. In this case, death follows within minutes.
The airways may become totally blocked, which could result in death.
Calling your health care provider
Call the local emergency number (such as 911) if your child has symptoms of epiglottitis, including sudden breathing difficulties, excessive drooling, and irritability.
Immunization with the Hib vaccine protects most children from epiglottitis.
The bacteria that causes epiglottitis is contagious. If someone in your family is sick from this bacteria, you need to be tested and treated appropriately.
