Abstract
At the April meeting of this year, we reported that by means of continuous intra-tracheal insufflation of air, we succeeded in keeping up the life of curarized animals. We do not intend to discuss now this subject theoretically, but wish to demonstrate this method in its simplified form.
A stomach tube, having only one opening at its lower end, is introduced, through mouth and larynx, in the upper end of the right bronchus. The outside end of the tube is connected by means of a T-tube with a manometer and a bottle containing ether. This bottle is connected with glass blowers bellows, which are so handled that the pressure is kept up at about 15 millimeters of mercury. The dog has been operated nearly two hours before and the thorax has been opened transversely, so that lung and heart are freely exposed. The lungs are continuously moderately distended and quiet and the heart beats strongly and regularly.
