What this Trial Is About

Researchers are evaluating the safety and effectiveness of three types of laryngeal masks—the traditional inflatable BlockBuster, the non-inflatable i-gel, and the new GMA-TULIP non-inflatable laryngeal mask—in patients undergoing surgeries in the lateral position under general anesthesia. Laryngeal masks are commonly used to manage the airway during anesthesia and are preferred over tracheal intubation because they cause less mechanical damage and maintain hemodynamic stability. The study aims to provide evidence for selecting the best laryngeal mask during surgeries performed in the lateral position, where mask displacement and air leakage can be concerns. Participants will receive one of the three laryngeal masks after anesthesia induction for airway ventilation during surgery. The GMA-TULIP mask features anatomical design improvements, such as a C-shaped double gastric tube channel and a soft tissue sealing ring, potentially offering better airway sealing. The study compares these devices by measuring oropharyngeal leak pressure at specific times after mask insertion, including one minute after insertion and at 5 and 30 minutes while the patient is in the lateral position. During the study, participants will undergo monitoring of airway sealing performance and safety. Researchers will assess the oropharyngeal leak pressure to evaluate how well each mask seals the airway. The study includes patients aged 18 to 80 undergoing surgery expected to last less than 3 hours in the lateral position. Patient consent and ability to participate in assessments are required, and careful monitoring will help determine the best airway management device for these surgical conditions.
