[Acute bronchial obstruction in infancy--therapeutic concepts].

Acute wheezing in infancy is a very common problem in pediatric practice. One diagnosis is RSV-bronchiolitis in the very young infant, but more often acute wheezy bronchitis will be diagnosed, which is also induced by viral infection and may be the first exacerbation of asthma. Both require the same basic therapy, but there ist no agreement about the therapy with bronchodilators. Similarly their is controversy about the use of antiviral agents for RSV-bronchiolitis. The most important strategies for the acute, and not the long term therapy, will be reviewed and discussed.
