Treatment of Persistent Wheezing in Infants and Children

Completed · Not applicable

Conditions studied: Asthma, Respiratory Sounds

In brief

Wheezing is a high-pitched whistling sound that is produced when air flows through narrowed lung airways. It is a common symptom of asthma. Persistent wheezing is commonly treated with bronchodilators and inhaled steroids; however, when wheezing is temporarily caused by a virus or exposure to tobacco smoke, this may not be the most effective treatment. The purpose of this study is to evaluate the cause of wheezing in infants and children and to assess the effectiveness of inhaled steroids on improving lung function.
