What is Bronchiolitis?
Jessica Ester, ARNP
December 2009
Bronchiolitis is an infection of the small air passages in the lungs. It results in narrowing of the
airways as a result of inflammation caused by any of a number of viruses, usually the respiratory syncytial virus (RSV). RSV occurs in epidemics almost every winter. Bronchiolitis is a common illness in babies and young children. It usually occurs during winter and early spring. Children over age 2 and adults will usually only develop cold symptoms from RSV while children under 2 years old may develop bronchiolitis.
Good prevention steps…
WASH HANDS FREQUENTLY
Keep baby away from smoke
Keep baby away from places where there are a lot of sick kids
If your infant was born prematurely (less than 35 weeks), talk with your pediatrician to discuss medicine that may help to prevent this infection since premature infants are at a higher risk for infection.
Signs/Symptoms of Bronchiolitis
Bronchiolitis usually starts as a common cold with fever, runny nose, congestion, and poor appetite
After several days, the baby may start wheezing, have difficulty breathing, or breathe fast (greater than 40 times per minute). The wheezing is caused by a narrowing of the small airways.It will sound like a high pitched whistling sound.
There may also be a sticky wet cough along with lots of sticky nasal mucus.
More severe symptoms include bluish skin and/or using the stomach muscles to help breathe
Treatment
Since bronchiolitis is caused by a virus, babies usually get better without treatment. In severe cases, babies may be admitted to the hospital for close monitoring of oxygen saturation, supplemental oxygen, intravenous fluids, and/or possible suctioning. The main course of treatment is to treat the signs/symptoms and make the baby as comfortable as possible.
This includes:
Warm fluids for coughing spasms.Encourage an increase in oral fluids and consider smaller more frequent feedings.
Keep the baby’s nose clear by using saline nasal spray and bulb suction. If a baby has a nose that is blocked with sticky mucus, it will make nursing or drinking a bottle more difficult.
Humidify the air with a cool or warm mist humidifier. Make sure to keep the filters clean as to not allow bacteria growth in the humidifier.
It has been proven that antibiotics are not beneficial in the treatment of bronchiolitis since it is cause by a virus.
Tylenol as needed for fever or discomfort. Ibuprofen may be used in babies greater than 6 months old. Contact your pediatric office for proper dosing.
Medicines that a baby breathes into the lungs are sometimes tried in the office and sometimes given at home. Medications such as albuterol and steroids are seldom used because they have shown to have little benefit.
When to call your pediatrician
If you have any questions/concerns about caring for your baby.
If signs/symptoms worsen after 4 days.
If baby is not drinking enough (less than 2 wet diapers per day or less than half or normal intake)
If your baby is in the high risk category (ex: premature, heart or lung disease, nervous system disease)
Suggestion of an ear infection (common complication of bronchiolitis that occurs in about 20% of bronchiolitis cases)
When to go to the Emergency Department
Baby has a bluish color
Baby is very sleepy or acting very sick (unable to be consoled, listless, unresponsive)
Baby’s breathing is fast and shallow (greater than 60 breaths per minute)
Baby is using his/her
stomach muscles
to breath. When he/she breathes, its ribs suck in and its nose flares.
