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.
