Clinical Trial[Analysis of ventilation parameters before and after fiber optic bronchoscopy in patients with atopic bronchial asthma and chronic obstructive pulmonary diseases].
Bronchial asthma and chronic bronchitis in a stable period of the disease could be an indication for diagnostic bronchofiberoscopy. The aim of the authors of this article is to assess whether bronchoscopy may be safely used either as diagnostic or therapeutic procedure. 21 patients (age 33-46), 13 with atopic bronchial asthma and 8 with COPD took part in this study. The measurements were carried out one day before and 3 hours after the bronchoscopy. ⋯ Bronchospasm was not observed during the study. Moreover the increase in FEF50, FEF75 and R aw were observed. This significant decrease of amount of bronchial discharge could serve as an explanation of this phenomenon.
