If you believe your child needs immediate attention and you have concerns for a life-threatening emergency, call 911. Not sure what counts as urgent and what's an emergency when your child is sick or injured? When it can't wait, know where to take your kids.
Croup occurs when there is inflammation of the upper airway (larynx and trachea) that causes a barking cough or hoarseness. The inflammation is caused by a virus.
Croup symptoms generally peak 2 to 3 days after the symptoms of the viral infection begin and typically last 3 to 7 days. Symptoms are worse at night and when the child is excited, exercising or crying.
The vast majority of children recover from croup with no complications. Rare complications of croup include a bacterial infection of the airway, dehydration from not being able to drink adequately and the need for supplemental oxygen. Children who were born prematurely or who have a history of lung disease (such as asthma) or neuromuscular disease (like cerebral palsy) are more likely to develop severe croup symptoms and often require hospitalization. Still, croup rarely causes any long-term complications.
Immediately call your doctor or get medical attention if your child has any of the following warning signs of respiratory distress:
Most cases of croup are caused by viruses. Parainfluenza virus, adenovirus and respiratory syncytial virus (RSV) are the most common types of virus that cause croup. Most cases of viral croup are mild and can be treated at home. In rare occasions, croup can be severe and even life threatening.
The best way to keep your child from getting croup is practicing good hand hygiene. Wash hands before eating or touching your eyes, nose and mouth as well as after being in contact with other people with respiratory infections.
Croup tends to occur in younger children (6 months to 3 years) because their airways are smaller, and a little swelling in a smaller airway makes a bigger difference. However, it can occur in older children as well. Croup tends to develop in the fall and early winter during the peak season for the viruses. Many children who come in contact with the viruses that cause croup will not get croup, but will instead have symptoms of a common cold.
Symptoms of croup are typically worse at night and when children are upset or crying.
Tests are not necessary to diagnose croup unless doctors suspect another condition is causing your child's symptoms. This can sometimes be the case because if the inflammation has an unusual presentation or unusual response to traditional croup treatments.
If your child has the warning signs listed on the overview page, other tests may be done to look for other causes of stridor.
Doctors can usually diagnose croup by listening for the telltale barking cough and stridor. They will also ask if your child has had any recent illnesses with a fever, runny nose and congestion, and if your child has a history of croup or upper airway problems.
Croup is typically mild. Breathing in cold or moist air helps most kids feel better. You can run a hot shower to create a steam-filled bathroom where you can sit with your child for 10 minutes. You can also bundle up your child and bring him or her outside for brief stretches to breathe cool air.
If your child has a sore throat, acetaminophen or ibuprofen (in children over 6 months old) or warm beverages, such as warm milk, can make your child more comfortable.
Staying hydrated is always important in any illness. Be sure your child drinks fluids regularly.
If your child has the warning signs of croup, have your child evaluated by a medical professional. Doctors often treat croup with steroids to decrease airway swelling. In severe cases, doctors will give a breathing treatment that contains epinephrine. This reduces swelling in the airway quickly. Oxygen also may be given, and sometimes a child with croup will remain in the hospital overnight for observation.
At Children’s Hospital Colorado’s Breathing Institute, our specialists are on the forefront of evaluating new medications for breathing treatments. Our researchers work to understand the conditions in pediatric cases, and then seek new ways to safely improve treatments. For example, our providers led a research study to help improve the quality and consistency of care for children with croup.
In our clinics, we believe a multidisciplinary approach to breathing and lung condition management is the best way to improve quality of life for our young patients. Children's Colorado's emergency and inpatient services and the wide range of available pediatric subspecialists all contribute significantly to our ability to provide a full spectrum of care.
Extensive diagnostic testing is available when appropriate for both infants and older children. An experienced staff of doctors, nurses, dieticians, social workers, child life therapists and therapists allows families to benefit from the team approach to the evaluation and management of patients with breathing and lung conditions. Our collaborative approach also incorporates and encourages family involvement and includes close collaboration with your child’s primary healthcare provider.
