Abstract

Jesberg1 stated in 1941 that the bronchoscopic examination of young infants presents an unusual risk because of the anatomically small glottis and subglottis. The hazard is further increased by inflammatory swelling of these regions. He further stated that the then existing bronchoscopes fit the glottis too snugly and often could not be passed without force. Accordingly, he and, a short time later, Holinger2 developed distally lighted bronchoscopes of smaller outside diameter which, nevertheless, preserved a good working lumen. The development of both instruments was dependent on a smaller bulb, and both men used light carriers.

The instrument described here has an even larger lumen, owing to the elimination of the light carrier. Instead, two insulated "hair wires" are buried in the wall of the bronchoscope tube so that they do not project either to the inside or to the outside (fig. 1). Two distally placed "grain of wheat" lamps
