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. This study aimed to demonstrate the effectiveness and tolerability of this PVC-designed GLA-II and evaluate its ability to suction secretions.
METHODS: The prospective cohort study included 100 gastrointestinal (GI) cases to determine the effectiveness and toleration of the GLA-II. The American Society of Anesthesiologists (ASA) class 1-3 patients were evaluated with a Mallampati airway score for GI-related procedures. After anesthesia induction with propofol, the GLA-II was inserted, and the time for successful insertion was recorded. All cases were completed within 62 minutes. During this time, the secretion volumes were also measured.
RESULTS: One hundred patients were included in the study: 52% were males and 48% were females. Thirty-four patients were scored as ASA class 1 or 2, while 66 were scored as ASA class 3. The GLA-II insertion was successful on the first attempt in 92 patients, and a second attempt was necessary for six patients. It was unsuccessful in two patients. The average time for successful insertion was 28.3 ± 4.3 seconds. The average amount of saliva suctioned was 9.3 ± 2.6 mL. There were no intraoperative or postoperative complications during these cases.
CONCLUSION: The PVC GLA-II device is distinguished by its ability to allow suctioning during placement. With an adequate epiglottic seal, it can be safely and successfully inserted in a short period of time. More research should be conducted to explore the use of GLA-II devices in other settings, such as emergencies and life-saving scenarios.
