What is bronchiolitis?: Symptoms, treatment and much more


bronchiolite – inflammation of the small respiratory tract Lungsthe Bronquioles . Usually, it affects babies and children up to 2 years old and almost always caused by a respiratory virus.Bronquiolitus can usually be diagnosed according to symptoms that include cough, hoarse and soft fever. There are no specific procedures for bronchiolitis, although greater hospitalization with oxygen therapy for severe cases may be required.

, also known as

bronchiolitis, is sometimes called pediatric bronchiolite to differentiate it from bronchiolite over oblitenes , disease, disease,which affects adults and most of the time caused by the inhalation of toxic vapors or complications of transplant lung .

Symptoms of broncipolitis

Symptoms of the result of theBronchipolito Bronchrón de Bronching Bottom Respiratory Infection .They look like ordinary colds,But progress affected as bronchiolos: / P>

  • Nasal secretion
  • header of nose
  • soft fever
  • cough
  • hheezing
  • bad feed

after shapskip Symptoms,Cough and wheezing may persist for several weeks. Most cases of broncipolitis are self-limited and do not cause damage or long-term injuries.

Some children with bronchipols can be the experience of (middle ear infection), which manifests itself with the ears of pain and dizziness, or tract infections urinary (ITI), recognized crying during michtion and cloudy urine,dirty.

In rare cases, bronchiolite can cause severe dehydration (due to poor diet), respiratory distress (inability to recover breathing),or A> (inability to keep up with the requirements of the oxygen organism).

When I call 911

Call 911 or go to your nearest emergency care department if your child develops signs of heavy broncipolitis,Including:

  • fast breathing ( tachipne )
  • nasal flash or hurry while breathing
  • Short breaches in breathing ( apnea)
  • husky while exhale and inhalation
  • Listening to crisp sounds when breathing( crepitus )
  • to eat or disability to eat due to problems with breathing
  • viscosity or weakness
  • Blue skin or nails ( cianosis ) caused by the oxygen (/ li>

bronchiolitis rarelyIt is fatal. Even if the child with the condition should be hospitalized, the probability that they do not survive, less than 1%; Only five of every 100,000 children who develop bronchiolitis die as a result.


Bronchiolitis is almost always caused by one of these respiratory viruses:

State begins with an acute infection of epithelial cells,What smaller respiratory tract chains.

In adults and older children, these common viruses They usually affect only the upper respiratory tract ,Because the immune system is able to limit its distribution. But because babies and younger children still have a strong or reliable immune response, viruses like this can easily infiltrate the lower respiratory tract.

When this happens, the infection will cause an inflammatory response that makes compressible bronchiols (narrow).Inflammation, in turn, causes skin cells in the respiratory tract to the release of excess of slugs , causing an obstacle and characteristic rather.

Risk factors

There are a number of risk factors, which can predict a child in bronchiolite:

  • Pre-birth
  • less than 3 months at the time of infection / li>
  • in to keep
  • mother smoking during pregnancy
  • Congenital heart disease
  • Primary immunodeficiency disease (PIDD)
  • Chronic lung disease and other chronic diseases


BronquiolitDiagnosticated with a clinical exam. This will include a physical examination,as well as an overview of the child’s symptoms and the history of the disease that is denied

The physical examination will include the listening of breathing sounds with a stethoscope to detect the Cruitillers and the Cotera tracks or highly adhesiveUsed.Characteristics of lower respiratory infections. Rapid breath and nasal flashes are other fairy tales.

Rapid tests are available to detect certain viruses.But, since the results look little affected on how infection is administered, they are not usually executed if the symptoms are not serious or recurrent.

In addition, some rapid tests, such as those used for RSV, have a relatively low specificity and sensitivity, which means that or negative it’s possible. The only exception may be testing RSV during local flashes to identify and insulation of children to avoid community distribution.

This is not unusual for children with bronchipols to develop a secondary bacterial infection.Since the UTI cases can be treated, you can request a moss of information

Differential diagnosis

Christ and cough in children can be caused by any number of things.If the diagnosis of bronchipolitis is uncertain, the doctor can perform additional tests to exclude other possible causes.They may include:


The treatment of bronchiolitis supports mainly.If secondary bacterial infection is not identified, antibiotics are not prescribed because they are only related to bacteria, and not for viruses.

With the exception of influenza, there are no antiviral medications , capable of treatment of viral respiratory infection.

The product Tamiflu (ovelltamivir) can reduce the gravity of the flu in babies and babies when taken within 48 hours after the first symptoms.At the same time, the sharp symptoms of bronchipolite, as a general rule, are being developed for three to five days of exposure, which means that the medication can be better to prevent bronchiolite to treat it after it occurs.

Soft at temperature Bronchipoly is a tendency to solve completely for two or three weeks without treatment. Most guidelines recommend bedding with sufficient liquids and nutrition.It is also important to keep a child with bronchiolite from smoke.

If your child has a fever, ask your pediatrician if you can use the children’s thyleol (acetaminophen) (acetaminophen) or children’s reasons ( Acetaminophen), both are available as syrups.

Do not give the child aspirin, since it provides the risk of Syndrome of Reye , rare, but potentially dangerous for living conditions.

Some parents love to use vapor inhalation or cold fog humidifiers to facilitate respiratory symptoms, although there is little evidence to support their use. .; If there is no respiratory disaster, these interventions will make little, if something will change the progress of the infection.


Up to 3% Babies in the United States require hospitalization as a result of bronchipolitis. Grave cases often require more aggressive interventions to avoid or treat the disadvantage of breathing, including:

  • oxygen therapy (generally,If oxygen saturation less than 90%)
  • intravenous fluids (IV) for treatment of dehydration
  • Nebulized salt inhalation,To help pour the mucus
  • the superior respiratory respiratory airway

so soft to moderate cases, inhaled armored vehicles or Steroids can facilitate the help of symptoms or recovery.


Currently there are no vaccine to prevent RSV, cold virus or ParandFleenz virus.

Prevention of influenza, Disease Control and Prevention Centers (CDC) recommend annual influenza images for 6 months or more. For people between 2 and 49, and the vaccine was also available against the nasal flu vaccine . Vaccination against influenza for the entire home is very important in families where there is a baby, elderly or others with high risk of influenza complications

During the cold or flu season,The risk of infection can be reduced with a dedicated manual washing, avoiding the mouth-third party and isolation of any person with suspicion or active infection.

If there is a local RSV flash in kindergarten or preschoolers institutions, it is important to pull your child until health care officers tell you that it is safe to return.

Note , however, that SINAGIS is not approved for the treatment of RSV.The study published in the magazine pediattics in 2019 concluded that the drug had no effect, good or bad, when used in 420 babies with acute RSV infection.
