“…Size of the ILA was decided according to manufacturer’s recommendation (air‐Q size 1.0 [weight 3–7 kg] and size 1.5 [weight 7–17 kg]). The cuff of the ILA was inflated with air, till cuff pressure of 60 cm H 2 O (6). Air‐Q ILA was connected to the anesthesia machine, and successful placement was confirmed by bilateral chest expansion with square‐shaped capnograph and achieving the expiratory tidal volume of at least 5 ml·kg −1 with positive pressure ventilation.…”

Summary Background: Air‐QTM intubating laryngeal airway (ILA) has been used successfully as a conduit for tracheal intubation in pediatric difficult airway. However, its use as an airway device and conduit for intubation in infants is not yet evaluated. Aims: The primary objective was to evaluate ILA as a conduit for tracheal intubation in infants, and secondary objectives were to evaluate ILA in terms of ease of insertion and ventilation, oropharyngeal leak pressure (OLP), glottic view, and complications. Methods: Twenty infants with normal airway were included. After induction of general anesthesia and neuromuscular blockade, ILA (size 1.0/1.5) was inserted. Fiberoptic bronchoscope (FOB)–guided intubation and removal of ILA with the stabilizing stylet was attempted. Results: The mean age and weight of the infants were 7.5 ± 2.3 months and 7.3 ± 1.8 kg. The ILA sizes 1.0 and 1.5 were inserted in 10 infants each according to the weight of the infants. The mean OLP was 18.5 ± 1.8 cm H2O, and mean time for insertion of ILA was 13.3 ± 3.9 s. Glottic view was grade I in 6, grade II in 1, grade III in 4, and grade IV in nine infants. Tracheal intubation was successful in 19/20 infants. The mean endotracheal tube (ETT) insertion time and mean total time (ILA insertion to the confirmation of ETT placement) were 95.6 ± 32.3 s and 306.42 ± 120.2 s respectively. Conclusion: The ILA is a safe and easy‐to‐use supraglottic airway device for intubation with FOB in infants with normal airway. Insertion and removal of ILA are easy with satisfactory oropharyngeal seal and ventilation.

“…The success rate of blind intubation has been reported to range between 15 and 97%, depending on the type of supraglottic airway, patient characteristics, and operator skill. [4][5][6][7] Although blind intubation What We Already Know about This Topic • When intubation and ventilation fail during anesthesia induction, insertion of a supraglottic airway device and intubation through the supraglottic airway device is a rescue plan to establish the airway. However, success rates ranging from 15 to 97% have been reported for blind intubation through a supraglottic airway.…”

BACKGROUND: Supraglottic airway devices commonly are used for securing the airway during general anesthesia. Occasionally, intubation with an endotracheal tube through a supraglottic airway is indicated. Reported success rates for blind intubation range from 15 to 97%. The authors thus investigated as their primary outcome the fraction of patients who could be intubated blindly with an Air-Qsp supraglottic airway device (Mercury Medical, USA). Second, the authors investigated the influence of muscle relaxation on air leakage pressure, predictors for failed blind intubation, and associated complications of using the supraglottic airway device. METHODS: The authors enrolled 1,000 adults having elective surgery with endotracheal intubation. After routine induction of general anesthesia, a supraglottic airway device was inserted and patients were ventilated intermittently. Air leak pressure was measured before and after full muscle relaxation. Up to two blind intubation attempts were performed. RESULTS: The supraglottic airway provided adequate ventilation and oxygenation in 99% of cases. Blind intubation succeeded in 78% of all patients (95% CI, 75 to 81%). However, the success rate was inconsistent among the three centers (P < 0.001): 80% (95% CI, 75 to 85%) at the Institute of Anesthesia and Pain Therapy, Kantonsspital Winterthur, Winterthur, Switzerland; 41% (95% CI, 29 to 53%) at the Leak pressure before relaxation correlated reasonably well with air leak pressure after relaxation. CONCLUSIONS: The supraglottic airway device reliably provided a good airway and allowed blind intubation in nearly 80% of patients. It is thus a reasonable initial approach to airway control. Muscle relaxation can be used safely when unparalyzed leak pressure is adequate.• In this multicenter, prospective study, 99% of 1,000 patients with a supraglottic airway could be oxygenated and ventilated. • Blind intubation succeeded in 78% of all patients, although the success rate significantly varied among the three centers (41, 80, and 84%), but when possible was easy, quick, and did not cause serious complications.

SummaryThis study assessed two disposable devices, the LMA Fastrach TM and the newly developed supraglottic airway device, the Air-Q TM , as a conduit for tracheal intubation in 154 healthy adults undergoing elective surgery. Using a non-inferiority approach, the primary outcome measure was successful tracheal intubation within two blind insertion attempts. Successful blind intubation after two attempts was achieved in 75 ⁄ 76 (99%) of the patients in the LMA Fastrach group vs 60 ⁄ 78 (77%) in the Air-Q group (95% CI for the difference 12-32%, p < 0.0001). Fibreoptic intubation was used to assist the third attempt. The rate of successful intubation after three attempts was 100% in the LMA Fastrach group and 95% in Air-Q group. The single-use LMA Fastrach appears superior compared with the Air-Q, as a conduit to facilitate blind tracheal intubation.
