What is Acute Bronchiolitis?
Acute bronchiolitis is a common respiratory tract infection involving the smallest breathing tubes in the lungs called the bronchioles.
How common is Acute Bronchiolitis?
Children under 2 years are especially prone to bronchiolitis. It is most common in males between 2 and 6 months old and in children who have not been breastfed. Please discuss with your doctor for further information.
What are the symptoms of Acute Bronchiolitis?
The disease starts out as an upper respiratory infection (URI) such as a common cold. The child will have a runny, stuffy nose and sneezing, but then, after a few days, fever and a harsh, tight cough appear.
The child will develop rapid breathing, and may use extra breathing muscles, especially in the neck, between the ribs and below the rib cage. The child will usually have difficulty with breathing out (exhalation) and wheezing may occur.
Very young children who develop bronchiolitis may have problems sleeping and eating. Large amounts of thick secretions in the airway may lead to vomiting or mucous in the stool.
There may be some symptoms not listed above. If you have any concerns about a symptom, please consult your doctor.
When should I see my doctor?
You should contact your doctor if you have any of the following:
If it’s difficult to get your child to eat or drink and his or her breathing becomes more rapid or labored, call your child’s doctor. This is especially important if your child is younger than 12 weeks old or has other risk factors for bronchiolitis — including premature birth or a heart or lung condition.
What causes Acute Bronchiolitis?
A virus usually causes the illness. Respiratory syncytial virus (RSV) is most common, but parainfluenza virus and adenovirus can also do it.
The viruses are spread from person to person by sneezing and coughing, and by direct hand-to-hand contact.
What increases my risk for Acute Bronchiolitis?
There are many risk factors for Acute Bronchiolitis, such as:

How is Acute Bronchiolitis diagnosed?
The diagnosis of bronchiolitis is based on clinical presentation, the patient’s age, seasonal occurrence, and findings from the physical examination, which may reveal the following:
When the clinical presentation, patient’s age, seasonal occurrence, and findings from the physical examination are consistent with the expected diagnosis of bronchiolitis, few laboratory studies are necessary. Diagnostic testing is controversial but is typically used to exclude other diagnoses (eg, bacterial pneumonia, sepsis, or congestive heart failure) or to confirm a viral etiology and determine required infection control for patients admitted to the hospital.
Commonly used tests in the evaluation of patients with bronchiolitis include the following:
Electrocardiography or echocardiography should be reserved for those few children who display arrhythmias or cardiomegaly.
Chest radiographs are not routinely necessary. A practical approach is to obtain a chest radiograph in children who appear ill, are experiencing clinical deterioration, or are at high risk (eg, those with underlying cardiac or pulmonary disease).
This imaging modality is most useful in excluding unexpected congenital anomalies or other conditions; it may also yield evidence of alternative diagnoses (eg, lobar pneumonia, congestive heart failure, or foreign body aspiration).
In rare situations (eg, severe immunodeficiency, strong history of possible foreign body aspiration), bronchoscopy may be indicated for diagnostic bronchoalveolar lavage or therapeutic foreign body removal.
How is Acute Bronchiolitis treated?
Among numerous medications and interventions used to treat bronchiolitis, thus far, only oxygen appreciably improves the condition of young children.  Therefore, therapy is directed toward symptomatic relief and maintenance of hydration and oxygenation.
Supportive care for patients with bronchiolitis may include the following:
Medications have a limited role in the treatment of bronchiolitis. Otherwise-healthy children with bronchiolitis usually have limited disease and do well with supportive care only.
The following medications are used in selected patients with bronchiolitis:
