Definition and epidemiology of Bronchiolitis
Bronchiolitis:
Definition:
• Acute viral infection of the LRT characterised by obstruction of the small airways with air trapping
Epidemiology:
- < 2 years of age (most severe 1-2 months), leading cause of hospital admissions in this age group
- Uncommon in children < 1month or >2 years - Almost exclusively an infantile disease
- Seasonal – mainly winter
Risk factors for Bronchiolitis
Risk factors:
- < 3 years – lungs and immune system have not developed fully
- Winter months
- Premature birth - impaired lungs and immune system
- Underlying heart or lung condition - E.g. CF or congenital heart disease
- Passive smoking
- Infants with older siblings – bring the infection home
Aetiology and Pathophysiology of Bronchiolitis
Aetiology:
- RSV is the most common cause (>50%)
- Others: Parainfluenza virus and adenovirus
Pathophysiology:
- Virus infection of the respiratory epithelial cells causing necrosis, inflammation, oedema and mucous secretion/plugging
- Cellular destruction and inflammation leads to obstruction of the small airways
- Results in hyperinflation, cilia dysfunction, atelectasis and wheezing
- Re-growth of the epithelial cell layers does not occur until ~ 2 weeks post infection
Clinical features of Bronchiolitis
Clinical Features:
- Prodrome of 1-3 days of irritating cough, nasal congestion and rhinorrhoea
- Wheezing – due to airway narrowing with mucus and necrotic debris
- Fluctuating clinical findings – Hallmark of bronchiolitis
- ↑ WOB – Tachypnoea + grunting, nasal flaring, subcostal retraction (common)
- Fever > 38.5°C
- Apnoea may be presenting feature, especially in very young or premature or low birth weight infants (uncommon)
- Worst day 3-4
Investigations, management and prognosis of Bronchiolitis
Investigations:
• Clinical
Rx:
- Supportive
- Hospitalise with respiratory distress
- Donʼt use steroids
Prognosis:
- Most cases are mild and self-limiting (3-10 days)
- Most get better in 2-3weeks (when resp. epithelium regenerates)
- Only 1% require hospitalisation
