Croup is a viral infection that usually affects children between the ages of 3 months to 5 years. In most cases, croup follows a cold. This illness is most often seen in the fall and winter during the cold season. Croup tends to reoccur during childhood, but attacks disappear as the child grows.
Common symptoms of croup include a low-grade fever; a brassy, barking cough; a hoarse cry; a harsh sound from the windpipe during inhalation called inspiratory stridor; and difficulty breathing. These symptoms are caused by mucus, swelling, and muscle spasms in the throat and windpipe. Symptoms usually appear in the evening and worsen at night. Croup may last from several days to several weeks.
Cool mist decreases fever; shrinks inflamed, swollen tissues in the throat and windpipe; decreases the muscle spasms in the throat and windpipe; and liquefies mucus so it moves easier. Directing a cool-steam vaporizer into the crib or playpen will create an area of cool mist. Covering the crib or playpen with a sheet will keep it comfortably warm. Another way to create an environment that is high in humidity and comfortably warm is to run the shower or tub water in the bathroom with the door closed for 15 minutes.
Generally ibuprofen does not help the inflammation that happens with croup.
