Q

URTI symptoms

LRTI symptoms

A

URTI: Coryza, sore throat, earache, sinusitis and stridor

LRTI: Cough, wheeze, respiratory distress

! Infants have compliant chest walls and poorly developed respiratory muscles and hence are greatly susceptible to respiratory failure!

Q

ASTHMA: Key features of history and examination that support a diagnosis of asthma

A

History:

  • Symptoms: Wheeze, non-productive & dry cough1, dyspnoea, tightness of chest, respiratory distress
  • Diurnal variation of symptoms
    • Worsened by change in weather/illness/exercise
  • Family/personal Hx of atopy (eczema, hayfever, asthma)
  • Recurrent episodes of wheeze, with interval symptoms2
  • NO coryzal symptoms/LRTI - evidence no virally induced wheeze
  • Positive response to asthma therapy (bronchodilators)

Examination:

  • Inspection: Inhaler, oxygen, nebuliser, respiratory distress, pectus cariatum, Harrison’s sulci, chest hyperinfltion
  • Chest ausculation: Audible general expiratory polyphonic wheeze, reduced air entry, prolonged expiration

1: In some children coughing may be the main symptom. Particularly at night.

Q

CHEST INFECTIONS - BRONCHIOLITIS: Understand the aetiology and natural history of bronchiolitis

A

Aetiology:

  • Viral: RSV (70%), adenovirus
  • Inflammation and accumulation of mucus within the airways
  • Premature infants with bronchopulmonary dysplasia, congenital heart defects and CF are at increased risk
    • IM vaccine available for at risk groups

Natural history:

  • Condition of infancy: Up to 1 year of age
  • More common in the winter months
  • Symptoms typically worsen at around day 3-5
    • May begin to experience reduced feeding and respiratory distress
  • Coryzal like symptoms → cough → day 4/5 peak → resolution by 2 weeks → dry cough may persist for several weeks

Q

CHEST INFECTIONS - BRONCHIOLITIS: Know how to treat acure bronchiolitis

A

Remember, the 2 main reasons for admission in bronchiolitis are LOW OXYGEN SATURATION and DEHYDRATION.

Management

  • Minimal handling to minimise respiratory distress
  • Provision of oxygen
  • Fluid challenge
    • ORT orally → with syringe → NG tube → IV
  • Inhaled therapies ! Little evidence of providing benefit
    • Ipatropium is preferred
    • Beta 2 agonists are not effective under 6 months of age
  • NPA to allow for bed management, blood gas to assess respiratory support, ENT examination

A
38
Q

A
  • ‘Steam treatment’ has often been advised but there is no evidence that it helps symptoms. It is not recommended
  • Try to calm and comfort your child on your lap
  • Paracetamol and ibuprofen may be used if the child is distressed due to fever
  • Symptoms usually resolve withi 48 hours

When to seek help

  • Call an ambulance in the event of cyanosis or severe breathing difficulty

Q

ENT: Be able to provide immediate care for a choking child.

A
  1. Ask the child to attempt to cough.
  2. If the cough is ineffective or the child is unconsciousness/unable to cough then proceed to back blows
    1. Under 1 year: Lie across legs and apply 5 back blows
    2. Over 1 year: Lean forward and apply 5 back blows
  3. If back blows are ineffective…
