Use of New Supraglottic Airway Devices in Severely Obese Patients: A Feasibility Study

The purpose of this study is to determine whether two new airway devices used during anesthesia called iGEL™ and KING-LTS-DTM work well and are safe in obese patients. They both work well in thin patients, but have not been tested in obese patients.

Stanford is currently not accepting patients for this trial.
