Croup is a viral infection of the vocal cords, voice box (larynx), and windpipe (trachea).
Symptoms of a croup include:
You may hear a harsh, raspy, vibrating sound when your child breathes in. This is called stridor. Stridor is usually present only with crying or coughing. As the disease becomes worse, stridor also occurs when your child is sleeping or relaxed. With severe croup, breathing becomes difficult.
Croup is usually part of a cold. Swelling of the vocal cords causes hoarseness. Stridor is caused by the opening between the vocal cords becoming more narrow.
Croup usually lasts for 5 to 6Â days and generally gets worse at night. During this time, it can change from mild to severe and back many times. The worst symptoms are seen in children under 3Â years of age.
First Aid For Stridor
If your child suddenly develops stridor or tight breathing, do the following:
Warm moist air seems to work best to relax the vocal cords and break the stridor. The simplest way to provide this is to have your child breathe through a warm, wet washcloth placed loosely over his nose and mouth. Another good way, if you have a humidifier (not a hot vaporizer), is to fill it with warm water and have your child breathe deeply from the stream of humidity.
In the meantime, have a hot shower running with the bathroom door closed. Once the room is all fogged up, take your child in there for at least 10Â minutes.
Cold air sometimes relieves the stridor. If it is cold outside, take your child outdoors. Otherwise, you can hold your child in front of an open refrigerator.
Try to help your child not be afraid by cuddling or reading a story. Most children settle down with the above treatments and then sleep peacefully through the night. If your child continues to have stridor, call your child's healthcare provider IMMEDIATELY. If your child turns blue, passes out, or stops breathing, call the rescue squad (911).
Home Care for a Croupy Cough (without stridor)
Dry air usually makes a cough worse. Keep the child's bedroom humidified if the air in your home is dry. Use a humidifier if you have one and run it 24Â hours a day. Otherwise, hang wet sheets or towels in your child's room.
Coughing spasms are often due to sticky mucus caught on the vocal cords. Warm fluids may help relax the vocal cords and loosen up the mucus. Use clear fluids (ones you can see through) such as apple juice, lemonade, or herbal tea. Give warm fluids only to children over 4 months old. Also give adequate fluids to prevent dehydration.
Medicines are much less helpful than either mist or drinking warm, clear fluids. Children over 6 years old can be given cough drops for the cough. Children over 1 year of age can be given 1/2 to 1 teaspoon of honey as needed to thin the secretions. Never give honey to babies. If not available, you can use corn syrup. If your child has a fever (over 102°F, or 38.9°C), you may give him acetaminophen (Tylenol) or ibuprofen (Advil).
While your child is croupy, sleep in the same room with him. Croup can be a dangerous disease.
Never let anyone smoke around your child. Smoke can make croup worse.
The viruses that cause croup are quite contagious until the fever is gone or at least during the first 3Â days of illness. Since spread of this infection can't be prevented, your child can return to school or child care once he feels better.
