Randomised study comparing insertion attempts, insertion time and postoperative complications (among other parameters recorded) on 37 adult patients after concerns that the i-gel sometimes fails to fit or ventilate sufficiently in Japanese patients. Results showed that two patients in the Air-Qsp group failed, compared to one in the i-gel group.
