The methods in use for the introduction of the oil into the bronchial tree are bronchoscopic, intratracheal, deglutitive, intralaryngeal and supralaryngeal. The introduction of a rubber tube through the nose and thence down into the trachea is also advocated.
Oughterson6 outlined the advantages of the intrabronchial injection of iodized poppy seed oil by means of a rubber tube, as follows:
