Patients and Methods: In a randomised, controlled study, we compared the performance of i-gel against the laryngeal mask airway (LMA) Supreme in 60 anaesthetised and paralysed patients for non-laparoscopic surgical procedures. Results: The primary outcome measure, the oropharyngeal leak pressure (OLP), was significantly higher for i-gel as compared to LMA Supreme (mean [standard deviation] 26.23 [4.09] vs 21.73 [3.19] cm H2O, respectively; P < 0.0001). Twenty-four (80%) of LMA Supreme and 22 (73.3%) of i-gels were successfully placed with similar ease on the first attempt to achieve an effective airway. The time taken for inserting the LMA Supreme was significantly less than that required for i-gel (mean [SD] 7.89 [1.6] s vs 11.48 [4.86] s, respectively; P < 0.0001). Gastric tube insertion was easier in the LMA Supreme as compared to i-gel (96.7% vs 63.3% respectively; P < 0.0001). There were no differences in the positioning of the supraglottic airway devices as evaluated fibreoptically. Postoperative sore throat was comparable with both devices. Conclusion: We conclude that while both these devices are suitable for routine use during maintenance of anaesthesia, a significantly higher OLP might provide the i-gel an advantage in this respect.
