Give 3 investigations for pneumonia
- Sputum cultures and throat swabs for bacterial cultures and viral PCR
- Blood culture
- CXR : consolidation
Give 3 chest signs of pneumonia
- Bronchial breath sounds
- Focal coarse crackles
- Dullness to percussion
Causes of pneumonia by age
- Newborn : GBS or enterococci
- Infant + > 5 yrs : strp pneumonia or RSV
Give 3 viral causes of pneumonia
- RSV -> most common
- Parainfluenza virus
- Influenzavirus
What is the management for mild pneumonia ?
-Oral amoxicillin
- Add macrolide if no response (e.g. erythromycin)
- Co-amoxiclav in pneumonia associated with influenza
What is the management for severe pneumonia?
-Iv benzylpenicillin
Define croup
-Acute, infective, URTI causing oedema of the larynx
What age group does croup typically affect?
-6mnths to 2yrs
What is the most common cause of croup?
-Parainfluenzae
Give 5 symptoms of croup
- ‘Barking’ cough
- Stridor
- Low grade fever
- Hoarse voice
- Increased work of breathing
How is croup managed if more than supportive care is needed ?
- Oral dexamethasone (single dose of 0.15mg/kg)
Explain the different age groups affected by bronchiolitis, viral induced wheeze and asthma
- > Bronchiolitis : 6mns usually (less than <1 yr)
- > Viral induced wheeze : <3 years
- > Asthma : >3 years
What is the most common viral cause of bronchiolitis ?
-RSV -> respiratory syncytial virus
What can be given to high risk babies to protect against bronchiolitis
- Palivizumab -> monoclonal antibody targeting RSV.
- Given as a monthly IM injection
How does bronchiolitis present ?
- Wheeze and crackles
- Coryzal symptoms
- Tachypnoea
- Dyspnoea
- Dry cough
- Poor feeding
- Mild fever

- Signs of respiratory distress
Give 8 signs of respiratory distress
- Raised resp rate
- Use of accessory muscles : sternocleidomastoid, abdominal and intercostal muscles
- Nasal flaring
- Heading bobbing
- Tracheal tug
- Cyanosis
- Abnormal airway noises
what would suggest a diagnosis of pneumonia over bronchiolitis ?
- High fever (>39 degrees)
- Persistently focal crackles
What 6 factors would suggest admission to hospital for bronchiolitis ?
- Oxygen at 92% or below
- RR >70
- Moderate to severe resp distress
- 50-75% less of nomral milk intake
- Apnoea
- Clinical dehydration
How is bronchiolitis managed in hospital ?
Supportive
What is the stepwise approach to ventilation support in bronchiolitis ?
- High-flow humidified oxygen via tight nasal cannula
- Continuous positive airway pressure
- Intubation and ventilation
What 3 factors suggest viral induced wheeze over asthma?
<3 yrs
- No atopic history
- Only occurs following a viral infection
What is the presentation of a viral induced wheeze?
- Evidence of a viral illness (fever, cough and coryzal symptoms) before onset of :
- SOB
- Expiratory wheeze throughout the chest
- Signs of respiratory distress
