Comparing GMA-TULIP, i-gel, and BlockBuster Laryngeal Masks for Airway Management in Laparoscopic Surgeries with Trendelenburg Position Under General Anesthesia

What this Trial Is About

Researchers are comparing three types of laryngeal masks used to manage airways during laparoscopic surgeries performed with the Trendelenburg position under general anesthesia. The study aims to determine which laryngeal mask—traditional inflatable BlockBuster, i-gel non-inflatable, or GMA-TULIP non-inflatable—best reduces postoperative throat pain and improves patient comfort and satisfaction. Laryngeal masks are widely used alternatives to tracheal intubation, with non-inflatable types recently developed to reduce complications such as sore throat and mucosal injury. The study evaluates the use of these three laryngeal masks during surgeries expected to last less than three hours in patients positioned in Trendelenburg. The GMA-TULIP mask is a new non-inflatable device designed to better fit throat anatomy and reduce injury, while the i-gel is a commonly used non-inflatable mask. The BlockBuster is a traditional inflatable mask requiring cuff inflation. Each device is applied during general anesthesia to manage the airway. Participants will be monitored for postoperative sore throat at multiple times: 10 minutes, 2 hours, 24 hours, 48 hours, and 72 hours after surgery. The study includes assessments of patient comfort and satisfaction and tracks safety and complications related to airway management. Eligible patients are adults aged 18 to 80 years undergoing specified laparoscopic surgeries with Trendelenburg position, with body mass index below 28 and ASA Grades I-III. The total study involvement includes anesthesia, surgery, and postoperative follow-up within three days after surgery.
