Acute bronchiolitis is an acute infection of the bronchioles less than 2mm in diameter, also known as bronchioles. The disease usually occurs in children under 2 years of age, especially children who are still breastfed (3-6 months). The typical symptoms of children with acute bronchiolitis are coughing, rapid breathing, and wheezing.
Causes of acute bronchiolitis in children are viruses such as respiratory syncytial virus (30-50% of cases), influenza and parainfluenza viruses (25%), adenovirus (10%). Pathogens attack the epithelial lining of the bronchi causing inflammation, edema, increased secretions, and increased mucus, especially in the bronchioles. If the bronchial area is severely damaged, it can cause spasm and obstruction in the bronchioles, causing atelectasis, alveolar gas retention.
Acute bronchiolitis in children often occurs in winter when the weather is wet, the disease has many levels, can be mild transient but can also be very severe, causing respiratory failure leading to death. Severe acute bronchiolitis usually occurs in children with risk factors such as:
Premature babies under 36 weeks, birth weight < 2500g, newborn respiratory failure Children under 3 months of age Children with medical conditions such as: congenital heart disease, congenital lung disease (pulmonary cystic fibrosis, bronchopulmonary dysplasia,...).
