An in Vivo CT Imaging Study of GMA-Tulip, I-gel, and LMA Supreme (GLAM-II)
Sponsor: Zhejiang Cancer Hospital
Summary
Laryngeal masks are core devices for supraglottic airway management, and the accuracy of their anatomical position directly impacts ventilation safety and the incidence of complications. Despite their wide clinical application, gaps remain in understanding their in vivo anatomical characteristics. This study aims to evaluate the in vivo anatomical features (e.g., insertion depth, anatomical alignment, tissue compression) of three laryngeal masks (LMA Supreme, I-gel, GMA-Tulip) using CT scanning in anesthetized patients undergoing CT interventional therapy, providing anatomical evidence for optimized laryngeal mask selection and complication prevention.

Conditions
Interventions
GMA-Tulip
Under general anesthesia, GMA-Tulip laryngeal mask is inserted following standardized protocols. CT scanning and fiberoptic laryngoscopy are performed to assess insertion depth, anatomical alignment, and tissue compression.
I-gel
Under general anesthesia, I-gel laryngeal mask is inserted following standardized protocols. CT scanning and fiberoptic laryngoscopy are performed to assess insertion depth, anatomical alignment, and tissue compression.
LMA-Supreme insertion
Under general anesthesia, LMA Supreme laryngeal mask is inserted following standardized protocols. CT scanning and fiberoptic laryngoscopy are performed to assess insertion depth, anatomical alignment, and tissue compression.
