CA 2318834

The disclosed method uses a cuffed oro-pharyngeal airway (COPA) (10) as an adjunct for fiberoptic endotracheal intubation. This allows control, and support of the airway during the procedure. The disclosed techniques take advantage of the upper airway distending effects of the COPA cuff (14) and ability for continuous ventilation. In fact, using the COPA cuff (14) appropriately with the fiberoptic scope (50) outside it, it is possible to have the cuff augment the size of the hypopharynx, lift the epiglottis, and facilitate fiberoptic intubation. The ability to perform fiberoptic endotracheal intubation while effectively supporting the airway using the COPA (10) may be advantageous in managing the difficult airway and in teaching the technique of fiberoptic endotracheal intubation.

Selon le procédé de l'invention, on utilise une canule oropharyngienne à ballonnet (canule COPA) comme un instrument d'appoint lors de l'intubation trachéale de fibres optiques, ce qui permet de commander et de soutenir la canule pendant l'opération. Les techniques proposées mettent à profit l'effet de dilatation de la canule supérieure, dû au ballonnet (14) de COPA, ainsi que la possibilité d'effectuer la ventilation en continu. En utilisant le ballonnet (14) de COPA de façon appropriée, conjointement avec un dispositif de visualisation à fibres optiques (50) se trouvant à l'extérieur, on peut augmenter au moyen dudit ballonnet la taille du laryngopharynx, soulever l'épiglotte et faciliter l'intubation des fibres optiques. La possibilité d'effectuer l'intubation trachéale de fibres optiques tout en soutenant efficacement la canule au moyen de COPA (10) peut s'avérer utile lors de la manipulation d'une canule difficile ou de l'apprentissage de la technique d'intubation trachéale de fibres optiques.
