A Comparative Study of the Air-Q ILA and the ILMA for Ventilation and Intubation

The objective of this study is to determine if the glottic view obtained with the air-Q Intubating Laryngeal Airway (air-Q ILA, Cookgas LLC®, Mercury Medical®, Clearwater, FL, USA) is better than that obtained with the traditionally used intubating laryngeal mask airway (LMA FastrachTM or ILMA, LMA North America Inc., San Diego, CA). The study will also compare effectiveness of ventilation.

Inclusion Criteria:

• healthy ASA class I and II patients scheduled for elective surgery under general anesthesia requiring the use of the LMA

Exclusion Criteria:

• history of acid reflux,
• a BMI ≥ 40kg.m-2,
• require endotracheal intubation,
• have predictors of difficult intubation,
• not candidates for insertion of an ILMA or LMA, including a mouth opening of less than 2.5 cm,
• cannot consent to the study
