Bronchiolitis in Children

What are the signs and symptoms of bronchiolitis?

The first symptoms of bronchiolitis are usually the same as those of a common cold:

• Stuffy/runny nose
• Mild cough
• Mild fever
• Mild wheezing (high-pitched whistling noises when exhaling)

Sometimes more severe respiratory difficulties develop, marked by:

• Fast, shallow breathing
• A fast heartbeat
• Retractions (drawing in of the neck and chest with each breath)
• Faring of the nostrils
• Irritability, with difficulty sleeping and signs of fatigue or lethargy
• Poor feeding and dehydration
• Apnea (pauses in breathing longer than 15 seconds)
• Cyanosis (blue color of the lips, tongue and skin)

You should seek immediate medical attention if your child is showing signs of severe respiratory difficulties.

Symptoms of bronchiolitis typically last about 12 days, but can last as long as 2 to 3 weeks.

How do providers at Children's Hospital Colorado diagnose bronchiolitis?

Bronchiolitis is usually diagnosed based on a patient's history and a physical exam. Your healthcare provider will look for cough, wheezing, trouble breathing and other signs of illness. Children will frequently have their oxygen levels checked. Most children do not require other testing. In some cases, diagnostic testing may be used, including chest X-rays, blood work or viral testing.

How is bronchiolitis treated?

Fortunately, most cases of bronchiolitis are mild and do not require specific treatment. The best treatment for most kids is time to rest and recover and drinking plenty of fluids. Fluids should be offered in small amounts and at more frequent intervals than usual.

To clear nasal congestion, try a bulb syringe and saline (saltwater) nose drops. This can be especially helpful just before feeding and sleeping. A cool mist-vaporizer or humidifier can help loosen mucus and relieve cough and congestion.

Acetaminophen can be given to reduce fever and make the child more comfortable. Be sure to follow appropriate dosing and timing of medication based on your child’s weight. Over-the-counter cough and cold remedies are not approved for infants and young children and are not recommended.

Antibiotics are not useful because bronchiolitis is caused by a viral infection, and antibiotics are only effective against bacterial infections. Breathing treatments with medicines such as albuterol or epinephrine are helpful for certain children and may be prescribed by your doctor.

Infants who have trouble breathing, pauses in their breathing, a blue color to their skin, are dehydrated or are sleepier than usual should always be evaluated by a doctor. Those who are moderately or severely ill may need to be hospitalized, watched closely, and given fluids and humidified oxygen. In very severe cases, some babies are placed on respirators to help them breathe until they start to get better, but this is rare.
