What is Acute Bronchiolitis/Bronchitis?

Acute bronchiolitis or bronchitis is an infection of the lower airways leading to the lungs. Both conditions are similar, except that the term bronchiolitis is generally used for children one year old and below, while the term bronchitis is generally used for children one year old and above.

What Causes Acute Bronchiolitis/Bronchitis?

Acute bronchiolitis or bronchitis is commonly caused by viruses ( for e.g. respiratory syncytial virus or RSV, rhinovirus, coronavirus, adenovirus, influenza, parainfluenza, human metapneumovirus etc.). It starts off like a common cold/cough before progressing downwards into the lower airways.

It can also be caused by bacteria such as Mycoplasma, which would require antibiotic therapy. Prolonged episodes of bronchiolitis/bronchitis can also be complicated by secondary bacterial infection (e.g. Staphylococcus/Streptococcus) which would require antibiotic therapy. Pollutants (e.g. second hand smoke or haze) can worsen bronchiolitis/bronchitis and must be avoided.

Does My Child have Bronchiolitis/Bronchitis?

Bronchiolitis/bronchitis usually starts out with signs and symptoms similar to those of a common cold but can quickly escalate to:
  • Phlegmy or chesty cough that worsens over time
  • Shortness of breath
  • Wheezing
Nasal congestion is also often present and will cause the cough to worsen because of post-nasal drip (back-flow of nasal mucus which irritates the throat). It can also cause severe vomiting induced by the bad cough, and if often mistaken as stomach flu. Fever is usually present, and it can be a high fever of 38.5 deg Celsius and above.

In the event your child experiences any of the following signs and symptoms, seek immediate medical attention:​

  • Persistent or worsening deep chesty/phlegmy cough, with nasal congestion
  • Shortness of breath e.g. rapid breathing, using neck/abdominal muscles to breathe, indrawing of rib muscles when breathing, nasal flaring
  • Audible wheezing
  • Severe vomiting induced by bad cough
  • High fever
  • Poor feeding
  • Lethargy

What are the Treatment Options for a Child with Bronchiolitis/Bronchitis?

Your paediatrician will personalise the treatment according to the severity and the cause of the bronchiolitis/bronchitis (most likely cause is usually germs).

There is often a need for nebulisation [using bronchodilators, such as Ventolin (Salbutamol) and Atrovent (Ipratropium), with added anti-inflammatory component such as Pulmicort (Budesonide)], to help open up the airways and loosen the phlegm.

Inhaled Ventolin puffs via the space chamber can also be used, depending on the paediatrician’s experience/preference, the child’s ability to cooperate and the child’s response to puffs (compared to nebulisation).

Other parts of the treatment may include antibiotics (e.g. Macrolides such as Clarithromycin/Azithromycin to treat Mycoplasma infection, or Penicillins such as Augmentin to treat secondary bacterial infection), oral steroids (especially in severe cases) and airway stabilisers (e.g. Ketotifen or Montelukast/Singulair). Symptomatic relief of nasal congestion and cough/phlegm may also be needed, including nasal suctioning/washes and symptomatic medications.

How do I Care for a Child with Bronchiolitis/Bronchitis?

During this period, ensure your child has plenty of rest and drinks enough fluids to keep well hydrated, so that the phlegm and mucus will not be too thick and prevent them from further plugging up the airways.

Keep your home clear of smoke or other pollutants.

Please bring your child back for the follow-up reviews with the paediatrician to ensure that your child’s respiratory status has improved. Hospitalisations may be needed for severe cases or those not responding to treatment.

For those with recurrent bronchiolitis/bronchitis or recurrent wheeze, especially when there is a family history of asthma/bronchitis, there may be a component of hyper-reactive airways and this group of children may require a longer period airway stabilisers (e.g. Ketotifen or Montelukast/Singulair) or inhaled corticosteroids (e.g. Flixotide) to calm the airways down and reduce the risk of recurrent wheezing and development of longer-term asthma.
