It is the experience of every bronchoscopist that bronchoscopic examination of young infants presents an unusual risk. The glottis and the subglottic region may be anatomically small, or in older infants this passage may be narrowed by inflammatory swelling, so that the standard instruments can be passed only with force or not at all. If the instrument is passed, the trauma attending the use of a tube which fits too tightly results in increase of the subglottic edema and makes a tracheotomy necessary.
To meet this problem there have been developed two new baby bronchoscopes. These are designed with the object of obtaining the greatest possible lumen with the smallest outside measurements. This is accomplished by the use of the new bronchoscopic light bulb, which is 1 mm. smaller in diameter than the standard bronchoscopic globe. The larger tube is 4 mm. in diameter and the smaller 3 mm. Both
