Abstract
For fiberoptic endotracheal intubation, a method is disclosed that uses a device having a cannula with a first, distal end for placement within the pharynx of a patient, a second, proximal end for being disposed outside of the patient's oral cavity, and a flow passage between the first and second ends. The cannula has a length such that, when the distal end is placed within the pharynx, it terminates distally at a point near the patient's epiglottis. The device includes an inflatable cuff structure for forming a seal between a wall of the cannula and the patient's pharynx. The cuff is positioned adjacent to the distal end of the device and defines, on inflation, a ventral/anterior portion and a posterior portion. The method involves a step of inserting the device, with cuff deflated, into a patient's mouth so that the distal end of the device is disposed at a point near the patient's epiglottis to establish an airway column down the core of the device. Once the cuff structure is inflated, the patient's airway is supported to provide spontaneous breathing and controlled ventilation through the flow passage of the device. Then, a fiberoptic scope, on which an endotracheal tube has be…
