As part of the awake airway management protocol initiated in the operating room, patients were first instructed to hold 10 mL of dyclonine mucilage orally for approximately 10 minutes to achieve topical oropharyngeal anesthesia. This was followed by intravenous administration of midazolam 2 mg and atropine 0.4 mg, and bilateral ultrasound-guided superior laryngeal nerve block using 0.375% ropivacaine. A properly sized laryngeal mask was selected. The posterior surface of the cuff was lubricated with a water-based surgical lubricant. Under awake conditions, patients were instructed to open their mouths to facilitate SaCoVLM™ insertion. Optimal positioning was confirmed by visualization of complete glottic structures on the monitor screen. The glottic exposure grade was as we previously described . The cuff was inflated using a handheld manometer, and the mask was connected to the anesthesia machine. Clear glottic visualization on the monitor and the presence of a regular EtCO₂ waveform.
