What type of therapy is typically not effective for the management of bronchiolitis?

Corticosteroids are typically not effective in the management of bronchiolitis, particularly in infants and young children. Bronchiolitis is commonly caused by viral infections, such as respiratory syncytial virus (RSV), and the primary approach to treatment is supportive care, which includes hydration, maintaining oxygenation, and providing suction for nasal congestion.

Research has shown that corticosteroids do not significantly improve outcomes for children with bronchiolitis. The use of corticosteroids for this condition is based on theories regarding inflammation, but clinical evidence has not supported their effectiveness in reducing the duration or severity of the illness.

Leukotriene receptor antagonists are also not effective for bronchiolitis, as they are more commonly used for asthma management and are not indicated for the viral nature of bronchiolitis. Therefore, while supportive care is the mainstay of treatment and is effective, corticosteroids do not contribute positively to management.
