Randomised controlled trial of 40 patients divided equally between i-gel and ETT groups. Leak fraction was the primary outcome, defined as leak volume divided by inspired tidal volume. In the LPT position, no difference was recorded in the leak fraction. In the i-gel group there was 'notably less' leakage in LPT position than in supine - this difference was not observed in the ETT group. Incidence of postoperative sore throat was significantly lower in the i-gel group.

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.

Patients were randomly assigned to either the i-gel or intubation group and induced using propofol or sevoflurane. Peak QTc interval was lowever in the i-gel group. Authors conclude the i-gel 'may be advantageous' to patients at risk of QTc prolongation.

90 adult patients were randomly assigned to LMA Proseal and i-gel groups, with voice evaluated using perceptive and acousitc analysis. In both groups voice results deteriorated comparably.

150 adult patients undergoing general anaesthesia were randomly assigned to 3 groups for ventilation via one of the SADs. Speed and ease of insertion, ease of gastric tube insertion, amount of gastric contents drained, leak pressure, and complications were all recorded. Patients were interviewed 1 and 24h after surgery to determine the incidence and severity of sore throat, hoarseness and dysphagia.
