“…Compared to blind tracheal tube placement, the use of fiberoptic guidance may improve intubation success through the air-Q with a similar time improvement profile and overall procedure time. Wong et al [7] studied blind tracheal tube placement through the air-Q in a manikin by anesthesiologists, fellows, and residents, and found a decrease (92.6 ± 22.7-60.8 ± 16.3 s) in overall procedure time over five consecutive attempts, similar to our findings, but observed a lower tracheal tube placement success rate. More than one in ten (34/325) blind intubation attempts resulted in failure due to esophageal intubation.…”

“…We did, however, observe three tracheal tube dislodgements during air-Q removal over the tracheal tube. This rate (3%) is similar to the 2% (6/291) rate reported by Wong et al [7]. Two of the three tracheal tube dislodgements occurred during trial 1 and the third dislodgement occurred during trial 3.…”

“…Blind placement of tracheal tubes through the air-Q was recently characterized [7]; however, fiberoptic-guided tracheal tube placement through the device was not studied. Insofar as visualization of the airway using a fiberoptic scope for intubation when the situation allows is preferable to a blind technique, as it provides visual confirmation of correct tracheal tube position in the airway, this represents a gap in our knowledge regarding the most efficacious way to use the air-Q as an intubation conduit.…”

“…With regard to using the ILA as a conduit for intubation, blind passage of the tracheal tube has been reported to be successful within three attempts in 60% 14 and 74% 11 , respectively. In a simulation model, time to completion improved by 34% after only five attempts with success rates of over 90% 15 .…”

The second-generation air-Q ® intubating laryngeal airway is a newer commercially available supraglottic airway device. In this retrospective review, we describe our initial clinical experience of 70 insertions. The ease and number of insertion attempts, airway leak pressure, device positioning, duration of use, success of fibreoptic-aided intubation and oropharyngeal morbidity were recorded. The intubating laryngeal airway was successfully inserted in all 70 patients and functioned adequately as a primary airway in all 57 patients in which it was used. The median airway leak pressure was 25 and 30 cmH 2 O for the single-use and reusable devices (P=0.001), respectively. Fibreoptic-aided intubation using the intubating laryngeal airway as a conduit was successful in 12/13 (92%) cases. One in four (26%) patients complained of mild sore throat postoperatively before discharge. In our series, the intubating laryngeal airway performed adequately as a primary airway during anaesthesia with respect to ease of insertion, adequacy of airway maintenance, and as a conduit for intubation in both anticipated and unanticipated difficult airways. Further investigation is warranted regarding the role of the intubating laryngeal airway as a conduit for both blind and fibreoptic-aided intubation. In addition, the incidence of postoperative throat complaints deserves further scrutiny.

“…Contrary to our findings Neoh and Choy (8) found that the presence of blood on the Air-Q ILA was significantly more than on the LMA Fastrach. Wong and Arora (15) recommended the use of the Air-Q ILA rather than the LMA Fast-track as a conduit for tracheal intubation, but this study had its own limitations of being done on mannequins rather than humans.…”

Objective: Our aim was to evaluate the Air-Q intubating laryngeal airway (ILA) as a primary airway device and conduit for tracheal intubation and to compare it with the intubating laryngeal mask airway (ILMA) which is currently the 'gold standard' supraglottic airway used as a conduit for tracheal intubation. Methods: Eighty patients of either sex, aged 18-60 years scheduled for elective surgery were allocated into two groups. In Group I (n=40), the intubating laryngeal mask airway was used to secure the airway and in Group A (n=40), the Air-Q intubating laryngeal airway was used. Both devices were then compared and assessed as ventilation device and intubation conduit. Results: ILMA had a higher first attempt intubation success rate (95%) as compared to ILA (72.5%) but both devices were comparable with respect to ease of placement and total time required for intubation. Conclusion: Both ILMA and ILA were comparable as primary airway devices. The first attempt blind intubation success rate was significantly higher in Group I.
