[Evaluating the safety of bronchoalveolar lavage in patients with bronchial asthma in light of gasometric and spirometric examinations].

Gasometric parameters were performed before, during and after bronchoalveolar lavage (BAL) in 21 patients with mild bronchial asthma. In addition, spirometric parameters were performed before and after BAL. Decrease of pO2, SaO2 and increase of pCO2 which kept within the limits of normal values were observed. After BAL gasometric parameters returned to baseline values. Bronchoalveolar lavage caused statistically significant fall in FEV1 and PEF. BAL was well tolerated and did not worse the clinical state of patients.
