Recommendations

People have the right to be involved in discussions and make informed decisions about their care, as described in NICE's information on making decisions about your care.

Making decisions using NICE guidelines explains how we use words to show the strength (or certainty) of our recommendations, and has information about prescribing medicines (including off-label use), professional guidelines, standards and laws (including on consent and mental capacity), and safeguarding.

1.1 Assessment and diagnosis

1.1.1

When diagnosing bronchiolitis, take into account that it occurs in babies and children under 2 years of age and most commonly in the first year of life, peaking between 3 and 6 months. [2015]

1.1.2

When diagnosing bronchiolitis, take into account that symptoms usually peak between 3 and 5 days, and that cough resolves in 90% of infants within 3 weeks. [2015]

1.1.3

Diagnose bronchiolitis if the baby or child has a coryzal prodrome lasting 1 to 3 days, followed by:

  • persistent cough and

  • either tachypnoea or chest recession (or both) and

  • either wheeze or crackles on chest auscultation (or both). [2015]

1.1.4

When diagnosing bronchiolitis, take into account that the following symptoms are common in babies and children with this disease:

  • fever (in around 30% of cases, usually of less than 39°C)

  • poor feeding (typically after 3 to 5 days of illness). [2015]

1.1.5

When diagnosing bronchiolitis, take into account that young infants with this disease (in particular those under 6 weeks of age) may present with apnoea without other clinical signs. [2015]

1.1.7

Think about a diagnosis of viral‑induced wheeze or early‑onset asthma rather than bronchiolitis in older infants and young children if they have:

  • persistent wheeze without crackles or

  • recurrent episodic wheeze or

  • a personal or family history of atopy.

    Take into account that these conditions are unusual in children under 1 year of age. [2015]

1.1.8

Measure oxygen saturation in every baby and child presenting with suspected bronchiolitis, including those presenting to primary care if pulse oximetry is available. [2015]

1.1.10

Suspect impending respiratory failure, and take appropriate action as these babies and children may need intensive care (see recommendations 1.2.1 and 1.4.5), if any of the following are present:

  • signs of exhaustion, for example listlessness or decreased respiratory effort

  • recurrent apnoea

  • failure to maintain adequate oxygen saturation despite oxygen supplementation. [2015]

1.2 When to refer

1.2.1

Immediately refer babies and children with bronchiolitis for emergency hospital care (usually by 999 ambulance) if they have any of the following:

  • apnoea (observed or reported)

  • baby or child looks seriously unwell to a healthcare professional

  • severe respiratory distress, for example grunting, marked chest recession, or a respiratory rate of over 70 breaths/minute

  • central cyanosis. [2015]

1.2.2

Consider referring babies and children with bronchiolitis to hospital if they have any of the following:

1.2.3

When deciding whether to refer a baby or child with bronchiolitis to secondary care, take account of any known risk factors for more severe bronchiolitis such as:

  • chronic lung disease (including bronchopulmonary dysplasia)

  • haemodynamically significant congenital heart disease

  • age in young infants (under 3 months)

  • premature birth, particularly under 32 weeks

  • neuromuscular disorders

  • immunodeficiency. [2015]

1.2.4

When deciding whether to refer a baby or child to secondary care, take into account factors that might affect a carer's ability to look after a child with bronchiolitis, for example:

  • social circumstances

  • the skill and confidence of the carer in looking after a child with bronchiolitis at home

  • confidence in being able to spot red flag symptoms (see recommendation 1.6.1)

  • distance to healthcare in case of deterioration. [2015]

For a short explanation of why the committee made the 2021 recommendation and how it might affect practice, see the rationale and impact section on when to refer.

1.3 When to admit

1.3.2

When assessing a baby or child in a secondary care setting, admit them to hospital if they have any of the following:

  • apnoea (observed or reported) [2015]

  • persistent oxygen saturation (when breathing air) of:

    • less than 90%, for children aged 6 weeks and over

    • less than 92%, for babies under 6 weeks or children of any age with underlying health conditions [2021]

  • inadequate oral fluid intake (50% to 75% of usual volume, taking account of risk factors [see recommendation 1.3.3] and using clinical judgement) [2015]

  • persisting severe respiratory distress, for example grunting, marked chest recession, or a respiratory rate of over 70 breaths/minute. [2015]

1.3.3

When deciding whether to admit a baby or child with bronchiolitis, take account of any known risk factors for more severe bronchiolitis, such as:

  • chronic lung disease (including bronchopulmonary dysplasia)

  • haemodynamically significant congenital heart disease

  • age in young infants (under 3 months)

  • premature birth, particularly under 32 weeks

  • neuromuscular disorders

  • immunodeficiency. [2015]

1.3.4

When deciding whether to admit a baby or child, take into account factors that might affect a carer's ability to look after a child with bronchiolitis, for example:

  • social circumstances

  • the skill and confidence of the carer in looking after a child with bronchiolitis at home

  • confidence in being able to spot red flag symptoms (see recommendation 1.6.1)

  • distance to healthcare in case of deterioration. [2015]

1.3.5

Clinically assess the hydration status of babies and children with bronchiolitis. [2015]

1.3.6

Do not routinely perform blood tests in the assessment of a baby or child with bronchiolitis. [2015]

1.3.7

Do not routinely perform a chest X‑ray in babies or children with bronchiolitis, because changes on X‑ray may mimic pneumonia and should not be used to determine the need for antibiotics. [2015]

1.3.8

Consider performing a chest X‑ray if intensive care is being proposed for a baby or child. [2015]

1.3.9

Provide parents or carers with key safety information (see recommendation 1.6.1) if the baby or child is not admitted. [2015]

For a short explanation of why the committee made the 2021 recommendation and how it might affect practice, see the rationale and impact section on when to admit.

1.4 Management of bronchiolitis

1.4.1

Do not perform chest physiotherapy on babies and children with bronchiolitis who do not have relevant comorbidities (for example spinal muscular atrophy, severe tracheomalacia). [2015]

1.4.2

Consider requesting a chest physiotherapy assessment in babies and children who have relevant comorbidities (for example spinal muscular atrophy, severe tracheomalacia) when there may be additional difficulty clearing secretions. [2015]

1.4.3

Do not use any of the following to treat bronchiolitis in babies or children:

  • antibiotics

  • hypertonic saline

  • adrenaline (nebulised)

  • salbutamol

  • montelukast

  • ipratropium bromide

  • systemic or inhaled corticosteroids

  • a combination of systemic corticosteroids and nebulised adrenaline. [2015]

1.4.5

Consider continuous positive airway pressure (CPAP) in babies and children with bronchiolitis who have impending respiratory failure (see recommendation 1.1.10). [2015]

1.4.6

Do not routinely perform upper airway suctioning in babies or children with bronchiolitis. [2015]

1.4.7

Consider upper airway suctioning in babies and children who have respiratory distress or feeding difficulties because of upper airway secretions. [2015]

1.4.8

Perform upper airway suctioning in babies and children with bronchiolitis presenting with apnoea even if there are no obvious upper airway secretions. [2015]

1.4.9

Do not routinely carry out blood gas testing in babies or children with bronchiolitis. [2015]

1.4.10

Consider carrying out capillary blood gas testing in babies and children with severe worsening respiratory distress (when supplemental oxygen concentration is greater than 50%) or suspected impending respiratory failure (see recommendation 1.1.10). [2015]

1.4.11

Give fluids by nasogastric or orogastric tube in babies and children with bronchiolitis if they cannot take enough fluid by mouth. [2015]

For a short explanation of why the committee made the 2021 recommendation and how it might affect practice, see the rationale and impact section on management of bronchiolitis.

1.5 When to discharge

1.5.1

When deciding on the timing of discharge for babies and children admitted to hospital, make sure that they:

1.5.2

When deciding whether to discharge a baby or child, take into account factors that might affect a carer's ability to look after a baby or child with bronchiolitis, for example:

  • social circumstances

  • the skill and confidence of the carer in looking after a baby or child with bronchiolitis at home

  • confidence in being able to spot red flag symptoms (see recommendation 1.6.1)

  • distance to healthcare in case of deterioration. [2015]

1.5.3

Provide parents or carers with key safety information (see recommendation 1.6.1) when the baby or child is discharged. [2015]

1.6 Key safety information for looking after a baby or child at home

1.6.1

Provide key safety information for parents and carers to take away for reference for babies and children who will be looked after at home. This should cover:

  • how to recognise developing 'red flag' symptoms:

    • worsening work of breathing (for example grunting, nasal flaring, marked chest recession)

    • fluid intake is 50% to 75% of normal or no wet nappy for 12 hours

    • apnoea or cyanosis

    • exhaustion (for example, not responding normally to social cues, wakes only with prolonged stimulation).

  • that people should not smoke in the baby or child's home because it increases the risk of more severe symptoms in bronchiolitis

  • how to get immediate help from an appropriate professional if any red flag symptoms develop

  • arrangements for follow‑up if necessary. [2015]
