This study compared the performance of i-gel® and cLMA airways in 50 healthy adult patients. The success rate on the first insertion attempt was significantly lower in the i-gel® group. Overall success after two attempts did not show a significant difference, although a change of device size was allowed. Leak pressures and fibreoptic view of the vocal cords were significantly better with the i-gel®, with the two devices producing leak pressures of 20 (i-gel®) and 17cm H2O (cLMA). 14 patients needed a change in i-gel® size.
