| Background The AIR-Q Laryngeal Mask (Cookgas LLC; distributed by Mercury Medical) is a supraglottic device present in the market since 2004. It has different sizes for pediatric and adult use. This device proved to be of utmost importance in the management of difficult airway []. The study evaluates the different adult sizes of the Air Q when used for intubation regarding the ease of insertion, the laryngeal view grade, their efficacy as conduit for standard cuffed endotracheal tubes using fiberoptic bronchoscope. The study also records the time of intubation, the ease and time of removal of the AIRQ over a removal stylet without dislodgement of the tube from trachea. Any complications related to the use of AIRQ were also recorded such as laryngeal oedema, blood streaked mucous, trauma to the airway, laryngeal spasm or aspiration. Methods Sixty adult patients aged 20–50 years, ASA I, II undergoing elective surgeries requiring general anesthesia, were enrolled in the study. The patients were divided into 2 equal groups according to their body weight. The body weight of the first group ranged from 50 to 70 kg and used the Air Q 3.5 for intubation with an endotracheal tube (ETT) 7 mm ID, while the body weight of the second group ranges from 70 to 100 kg and used the Air Q 4.5 for intubation with a tube 7.5 mm ID. The number of attempts of insertion, the seal pressure, the laryngeal view grade, the time and the number of attempts of intubation, time of removal of the AIRQ over the tube without dislodgement, and any complications related to the use of AIRQ were recorded such as laryngeal oedema, blood streaked mucous, trauma to the airway, laryngeal spasm or aspiration. Results The insertion and removal of the AIRQ were easy and successful in all patients of both groups. The endotracheal intubation by fiberoptic bronchoscope through the Air Q was successful and easy in both groups. Grade 5 laryngeal view was seen with AIRQ 4.5 in some patients with higher body weight. Conclusion The insertion of AIRQ in adult patients is easy and provides an effective conduit for the standard cuffed endotracheal tubes using fiberoptic bronchoscope. The removal of the AIRQ over the removal stylet is easy without dislodgement of the tube. Because of higher incidence of down folding of the epiglottis in some obese patients, they are better intubated under direct vision with the use of fiberoptic bronchoscope. | ||
