2. BRONCHIOLITIS
Bronchiolitis is an inflammation of bronchioles.

The infection spreads by infected droplets
(airborne or through direct contact with
secretions)
3.
4. Incidence rate:
Peak incidence occurs during winter and spring,
More common in boys than in girls (ratio 1.5:1).
Causative agent
Respiratory syncytial virus (RSV) 75% of the
cases
Parainfluenza virus (type 3),
Mycoplasma, or adenoviruses
5. RISK FACTORS OF BRONCHIOLITIS
Chronic lung disease
Congenital heart disease
Younger than 3 months old
Prematurity
Down’s syndrome
Cystic fibrosis
Neuromuscular disease
6. PATHOPHYSIOLOGY
Due to etiological factors.
Infection of the bronchiolar and ciliated epithelial cells produces
increased mucous secretion
cell death and sloughing
Peribronchiolar lymphocytic infiltrate and submucousal edema.
distal airway obstruction.
During expiration, the additional dynamic narrowing produces
disproportionate airflow decrease and air trapping
7. CLINICAL FEATURES
Moderate fever
Runny nose
Loss of appetite
Shortness of breath
Chest tightness.
Shallow & fast breathing.
Malaise
Cough
Dehydration
12. MANAGEMENT
Oxygen therapy:
Antibiotics: Based on type of infection.
Branchodilators: Theophylline & Etophylline
Nebulization : Albuterol.
Oral corticosteroids.: Prednisolone.
Chest physiotherapy & Postural drainage
13. NURSING CARE
