Supraglottic Airway Device

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.

This study aims to compare the effectiveness of SaCoVLM™ in artificial airway ventilation during general anesthesia, focusing on the correlation between native video camera imaging and fiberoptic endoscopy. Primary outcomes include the analysis of imaging correlation, while secondary outcomes assess initial placement success rates, difficulty, blood clot adherence, vital sign changes, and postoperative complications.
