In this study, 80 patients were randomly allocated to either i-gel® or LMA-Unique® insertion before minor surgery. Ventilation, insertion time, airway pressure, leak pressure and postoperative sore throat were all measured. Results were similar for all parameters other than airway leak pressure, which was significantly higher in the i-gel® (mean pressure 29cm H2O compared to 18cm H2O). Both devices are acceptable for use in securing an airway, however the increased leak pressure is an advantage for the i-gel®.
