title: [Procedure for bronchodynamic tests with inhaled allergens].
abstract: The asthma is one of the most frequent chronic illnesses in the children. It is characterized by hyperreactivity from the air roads to inspecific stimuli (metacholin and histamin) and specific (allergens). The broncodynamics tests determines the broncolability asthmatic boy's and they help to settle down the I diagnose functional. They should be carried out with antigenic extracts of high quality, lyophilized watery and standardized; you can use an open or closed circuit and a dosimeter, the initial dose of the allergen it is lower than with the one that the positive cutaneous reactivity was obtained, carrying out successive increments until the VEF-1 descend 15% or more. The patient's security is fundamental, they should be carried out for specialized personnel.
