- W2039237783 abstract "In 1896 G. Killianl constructed and devised a series of endoscopic instruments which are the precursors of the present day bronchoscopic equipment. The bronchoscope which is used universally today is the 1915 Chevalier Jackson modification of the Killian bronchoscope.1 Hill in 1909' introduced the idea of a slot in the standard laryngoscope which is covered by a removable spatula, this was made to facilitate instrumentation. At the same time he devised a slotted esophagoscope for the same purpose. Frenkner in 1934l described several instruments for endobronchial catheterization and for bronchospirometry. Among the instrumenta he described is a bronchoscope with an optical system similar to a cystoscope and a side lumen with a slide and slot to facilitate introduction and manipulation into position of urethral catheters for the purpose of gas sampling. The slide is removed once the catheter is in place and the bronchoscope is removed without dislodging the catheter. In 1952l. 2. a slotted bronchoscope* was described (Fig. 1) resembling the Hill esophagoscope. This bronchoscope had a wide slot along its whole length. I t was primarily used to facilitate the introduction of endobronchial blockers and removal of the bronchoscope for the control of secretions during anesthesia. I t was later found that the slot along the whole length of the bronchoscope presented certain advantages during routine bronchoscopy. A modified bronchoscope was then devised which has features similar to the Sill and Jackson laryngoscopes and a t the same time incorporates features of Frenkner's bronchoscope for bronchospirometry. The new type of slotted bronchoscope** is a modified Chevalier Jackson instrument with a slot along its whole length (Fig. 2). There are two interchangeable slides. A long slide which converts the slotted bronchoscope into a standard type (Fig. 3) and a short slide which covers approximately two thirds of the length of the slot (Fig. 4) , leaving the distal one third open. The slides can be removed and interchanged while the bronchoscope is in the tracheobronchial tree. These slides were found necessary in order to protect the teeth when the bronchoscope is rotated 360 degrees, a t the same time it keeps out the soft tissues in the oral cavity to fall inside the lumen of the bronchoscope and obstruct the visual field. For the past three years this type of slotted bronchoscope has been routinely used a t the George Washington University Hospital. Careful evalu-" @default.
