Air-Q® SP Versus Air-Q® and I-gel: A Randomized Clinical Trial

Completed · Not applicable

Conditions studied: Laryngeal Masks

In brief

The air-Q Self-Pressurizing Intubating Laryngeal Airway (aILA SP) is a modification of the air-Q Intubating Laryngeal Airway (aILA). Besides the i-gel, it is the only breathing tube that sits above the vocal cords that does not require inflation of a cuff with air. The purpose of this study is to compare the ability of the aILA-SP to maintain patency of a patient's airway during general anesthesia with that of the aILA and i-gel devices. As a measure of this ability, we hypothesized that the airway sealing pressures will be equal between the aILA-SP and aILA, but superior when comparing the aILA-SP to the i-gel (i-gel will be lower).
