• Conditions: Supraglottic Airway Devices Position

• Registration Number: NCT06775184
• Lead Sponsor: Kaohsiung Medical University Chung-Ho Memorial Hospital

Brief Summary

A comparison of SaCo VLMTM video laryngeal mask airway with the I-gel supraglottic airway during airway management in patients undergoing elective surgery.

Detailed Description

The position of the supraglottic airway is checked using a fiberoptic endoscope: The bronchoscope is placed at the opening of the laryngeal mask, and assessed using the following grading system: Grade 1: Vocal cords not visible. Grade 2: Vocal cords and anterior epiglottis visible. Grade 3: Vocal cords and posterior epiglottis visible. Grade 4: Only vocal cords visible.
