Croup is the situation in which the larynx (voice-box area of the throat) is affected by (usually) an infection which is characterized by difficult and noisy respiration and a hoarse cough. The cough is quite unmistakable, and usually sounds like a barking dog or seal.
Most infections are caused by viruses, especially those which cause the common cold, and in particular, one known as parainfluenza virus. Usually the episode begins with a simple upper respiratory infection, including a mild cough. The cough progresses to sound like a "bark" and is often worse in the late afternoon or evening hours. The child's breathing is often noisy or described as "stridorous."
In croup, the airway, known as the trachea, becomes swollen below the vocal cords. When the child coughs, air passing through the narrowed opening causes the "barking" noise. This situation is not the same as asthma; croup is not same as wheezing.
Treatment is usually symptomatic; that is, decongestants, and simple cough medications are usually helpful. Humidification of the child's room with a room humidifier or vaporizer, is often helpful, or even taking the child into a steam-filled bathroom. Keeping the child calmed-down is also helpful.
If breathing becomes labored, or the child's color is poor, treatments with racemic epinephrine in an emergency room may help, but are temporary. Some physicians are also now treating more severe croup with oral steroids.
