[Aspiration of barium contrast medium and its prevention]

The authors have been noted aspiration bronchograms associated with barium-filling study of the upper gastrointestinal tract in 58 patients involving basal medial, anterior, lateral and posterior segments of the lower pulmonary lobes, mammary segment of the middle lobe, moreover inferior lingula. In 75.9% of patients (44 cases) the barium meal got to bilateral basal medial, anterior and lateral segments. The 34 men and 24 women had a mean age of 69 years (range, 29-88 years). The aspiration was found 3.8-times more frequent after completion of patient's 50th year than before it observed. A transient tertiary mobility disorder of the esophagus, extrasystoles and tendency for collapse were on barium-filling of bronchi. In 15 of the 18 patients the Valsalva's maneuver proved a pharyngomyodystonia. Carrying out of endoradiography depended on function of the lateral pharyngeal wall. The bronchi with physiological saline following aspiration of the contrast medium within 30 minutes were lavaged.
