The Effectiveness of the Gnana Laryngeal Mask Airway II (GLA-II) With Novel Suction Tubing in Gastrointestinal (GI) Cases.

Introduction: The Gnana laryngeal mask airway II (GLA-II) is a supraglottic airway device similar to the classic laryngeal mask airway, except it has an additional suction port. This suction port allows for the removal of secretions and saliva. A previous version of the Gnana laryngeal airway 4 was made of silicone, while this newer version is made of polyvinyl chloride (PVC), which is more affordable.
