title: [The effect of fiberoptic bronchoscopy and bronchoalveolar lavage (BAL) on results of spirometric measurements].
abstract: The effect of fiberoptic bronchoscopy and bronchoalveolar lavage on the functioning of the respiratory system was studied in 72 patients (42 males and 30 females). The bronchoscopy was performed in the sitting position. Supplemental oxygen was not given to all the evaluated patients. The group included 24 patients with lung cancer, 9 with sarcoidosis, 12 with tuberculosis, 1 with farmer's lung and 10 with other lung diseases (pneumonia, COPD). A control group consisted of 16 patients who were undergoing routine diagnostic endoscopy but who were seen to be without lung disease. Group BF (39 individuals) received only a bronchoscopic examination, group BF+BAL (33 persons) received a bronchoscopy followed by BAL using 140 ml. of normal saline solution as a lavage fluid. After the bronchoscopic examination there were significant differences in all spirometric measurements, except MEF25. The bronchoscopy and bronchoalveolar lavage caused a transient fall in FEV1, VC, MEF50, MEF75 (7.7-9.4%) which was similar in both groups. These measurements returned to normal after 24 hours. The testing of pulmonary functioning before the bronchoscopy was seen to be clinically important for safety of the patient undergoing this procedure.
