The intubating laryngeal mask airway (ILMA) can be used for ventilation and oxygenation between intubation attempts, but there is a varied success rate ranging from 33% to 96%. Air Q is a relatively new entrant. Parker flex tube aids in atraumatic intubation. The primary aim of this study was to compare Air Q intubating laryngeal airway with ILMA as intubation conduits in patients with simulated fixed cervical spine using a Parker flex tube. It was a single-blinded, randomized, prospective, and comparative study conducted on 91 patients aged between 18 to 60 years of either sex, scheduled to undergo elective surgery under general anesthesia belonging to the American Society of Anesthesiologists physical status I and II. Out of 45 patients in each group, Air Q was successfully placed in 43 patients and ILMA was successfully placed in 44 patients. 35.56% of the patients required maneuvers for placing the Air Q, whereas, for placing the ILMA, only 15.56% of the patients required maneuvers. Intubation through the AIR Q was successful in 39 patients and through the ILMA in 44 patients, but there was no significant difference between the two groups. The number of attempts and the time of device insertion were comparable. There were a similar number of attempts, maneuvers required, and time is taken for endotracheal intubation. The incidence of cough and sore throat was comparable in both groups. We conclude that ILMA has a higher success rate than Air Q for tracheal intubation with Parker Flex tube in patients with simulated fixed cervical spine. More optimized maneuvers were required for the placement of Air Q.
