[Evaluation of the tussicular reaction in bronchial provocative testing with acetylcholine (author's transl)]

A simple method for registration of the tussicular effect in bronchial challenging is described. The results, obtained in this way, are discussed for their informative value. In bronchial challenging with acetylcholine tussicular reaction in all groups of patients is more frequent than broncho constrictive reaction. Evaluated on clinical defined diagnoses respectively anamnestic date there is a good sensibility of the test (index for sensibility 0.85). Till now the date of specifity are not satisfying. It could be solved only by means of longitudinal studies, if these "false-positive" results have an early diagnostive value with regard to beginning functional disturbances in the airways or if they coincide with diagnostic uselessness of the test.
