The i-gel is a supraglottic device with a soft, noninflatable cuff. Although insertion is usually successful, it sometimes fails because of tongue folding. Previous studies have shown that a rotational technique during insertion improves first-pass success with a laryngeal mask airway. The technique involves placing the device in the oropharynx and then rotating it 90° counterclockwise, inserting it past the tongue in this orientation until resistance is met at the hypopharynx, and then rerotating it clockwise back to the standard orientation.
To study the efficacy of a rotational technique for i-gel insertion, researchers randomized 181 patients undergoing general anesthesia to the traditional or rotational technique. After insertion by an …
