Bronchial drainage prior to bronchography--a possible modification.

Bronchography results were studied in 110 cases between the ages of 14 and 68 years. In each case the mucolytic agent Carbocysteine was used to increase the effectiveness of postural drainage prior to bronchography. Insufficient filling of the bronchial tree occurred in only one case. These results suggest that Carbocysteine increases the effectiveness of postural drainage prior to bronchography and indicates the need for further careful controlled studies.
