The Air-Q® intubating laryngeal airway (Air-Q® ILA) is an extraglottic device specifically engineered for use both as a stand-alone laryngeal mask airway (LMA) and as a rescue device or "Plan B" device in the event of a difficult airway. As with some other types of LMA, it is then possible to insert an endotracheal tube (ETT) through the Air-Q® ILA, either blindly or mounted on a fibreoptic bronchoscope (FOB), to achieve endotracheal intubation. The objective of this study is to compare the Air-Q® ILA's performance to the current best option, the PLMA.
Hypothesis: The hypothesis is that, for each of the four ILA size categories, 1.0, 1.5, 2.0 & 2.5:
H0: Mean oropharyngeal leak pressure with Air-Q® ILA= mean oropharyngeal leak pressure with PLMA.
H1: Mean oropharyngeal leak pressure with Air-Q® ILA≠ mean oropharyngeal leak pressure with PLMA.
Background: The laryngeal mask airway (LMA) is used during pediatric anesthesia for routine and difficult airway management. The ideal pediatric LMA device would provide excellent sealing at low pressure; facilitate easy endotracheal intubation; and be available in pediatric sizes. Such a device would be an invaluable addition to difficult pediatric airway management plans and, by increasing the likelihood of quickly and effectively securing the difficult airway, and decreasing the risk of catastrophic hypoxemia, would increase perioperative safety for children. The Air-Q® ILA is a modified LMA device whose features encompass the characteristics of the ideal LMA. Our objective is to determine whether or not this new airway device is an improvement over the current standard of care.
The objective of this study is to compare the Air-Q® ILA's performance to the current best option, the PLMA.
Recruitment of subjects: With ethical and institutional review board approval, and with written parental informed consent, we will recruit children undergoing elective surgery. Children with ASA status IV-V, abnormal or contraindicated cervical spine flexion/extension/rotation, contraindication to LMA placement, or requiring emergency surgery will be excluded. All children will undergo intravenous induction of anesthesia, as per our routine institutional practice.
Administration of Air-Q® ILA: In phase 2, either a PLMA or an Air-Q® ILA will be inserted and assessed. The first LMA will then be removed and the other device inserted and assessed. The order of insertion will be determined by block randomization.
Data analysis: In phase 2, we will compare OLP values using paired t- tests. We will conduct appropriate statistical analysis of the data on the other assessment variables, which are all secondary outcome measures. Descriptive data will be presented as mean ± SD, median (range), counts (percentages or proportions) as appropriate.
Allocation: Non-Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Treatment

Flexible reinforced laryngeal mask airway (FLMA®) has gained popularity in thyroid surgery, but air leak and displacement are still concerns.
A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.
Congenital anomalous dilitation of the laryngeal saccule that may extend internally into the airway or externally through the thyrohyoid membrane.
Cancers or tumors of the LARYNX or any of its parts: the GLOTTIS; EPIGLOTTIS; LARYNGEAL CARTILAGES; LARYNGEAL MUSCLES; and VOCAL CORDS.
A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).
Branches of the vagus (tenth cranial) nerve. The recurrent laryngeal nerves originate more caudally than the superior laryngeal nerves and follow different paths on the right and left sides. They carry efferents to all muscles of the larynx except the cricothyroid and carry sensory and autonomic fibers to the laryngeal, pharyngeal, tracheal, and cardiac regions.
