[Acute bronchiolitis and chest physiotherapy: the end of a reign].

Every winter, numerous infants are hospitalized for acute bronchiolitis. The severity criteria and symptomatic treatment are well known, with chest physiotherapy codified in 2000 by the French Health Authority (HAS) consensus conference (with techniques varying from one country to another) and becoming nearly systematic for the treatment of bronchial obstruction in infants. However, is this treatment really effective and legitimate for acute bronchiolitis? The objective of this study was to review the main studies on this subject. Few studies are available and most have a low level of evidence. However, they all tend to agree that chest physiotherapy does not change the natural history of the disease and most particularly the duration of hospitalization. Therefore, it does not seem that the prescription of chest physiotherapy in infant acute bronchiolitis is recommended.
