Zadrobilek E, Krystof G. The Guedel Oropharyngeal Airway: Seventieth Anniversary of the First Published Description


Development of Oropharyngeal Airways



In 1908, Hewitt reported on a rubber oropharyngeal airway (2). The first model of the Hewitt oropharyngeal airway was a straight and relatively short, bevelled rubber airway with a metal mouthpiece; it must have had only limited success as a controller of the tongue and soon a model with a curved pharyngeal section of uncertain origin extended its length. This airway was the forerunner of many oropharyngeal airway designs.


Seven years later, Lumbard communicated a new double-curved oropharyngeal airway (3). The Lumbard oropharyngeal airway was a metal open-cage airway consisting of a double row of four bent wires which were firmly held together by wire bands (two at each end). The Mayo oropharyngeal airway was also a metal open-cage airway but with a single row of bent wires (curved and rounded at the distal end) and fastening wire bands only at the proximal end. Modifications followed with an additional side feed tube for the fresh gas flow, the distal end distinctly narrowed (Lumbard modifcation), and/or with a removable metal-rubber bite-block section.


The Phillips oropharyngeal airway was a rubber airway with a curved pharyngeal section and a metal mouthpiece with holes at the side. Modifications of this airway were with an additional side feed tube at the mouthpiece (Hirsch modification) or with T-piece component fitting on the mouthpiece (Clausen-Evans modification) for the fresh gas flow.
