New Generation Supraglottic Ventilatory Devices

Nothing new under the sun

“…an upward angle of about 15-20°to align with the glottis (Figure 1a). Also, a keyhole-shaped outlet of airway tube is designed to limit excessive upward angle of the TT tip and direct the TT tip toward the glottis (3). When a TT is reversely inserted into the air-Q-ILA, however, the TT tip emerged from outlet of airway tube will move along the bottom of the cuff, pass above the distal end of the cuff (Figure 1b) and enter upper esophagus under the larynx, resulting in a failed intubation.…”

“…This problem may be more possible to occur in the infants and young children with an anterior larynx. 3. In the available literature, there is no clinical study with enough sample size to assess availability and safety of the blind intubation through the air-Q-ILA in pediatric patients with a difficult airway.…”

“…The 'Klein maneuver' is a useful measure to address this issue. It includes jaw lift and withdrawal of the air-Q-ILA, followed by reinsertion (3).…”

Reverse loading of the tracheal tube to facilitate blind intubation through the air-Q intubating laryngeal airway in children

“…As a result, the TT tip emerged from outlet of airway tube requires an upward angle of about 15–20° to align with the glottis (Figure 1a). Also, a keyhole‐shaped outlet of airway tube is designed to limit excessive upward angle of the TT tip and direct the TT tip toward the glottis (3). When a TT is reversely inserted into the air‐Q‐ILA, however, the TT tip emerged from outlet of airway tube will move along the bottom of the cuff, pass above the distal end of the cuff (Figure 1b) and enter upper esophagus under the larynx, resulting in a failed intubation.…”
