Official title
The Effect of Fiberoptic Bronchoscopy Examination on Supraglottic Airway Devices Position in Patients Undergoing Elective Surgery
Overview
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.
Interventions
- Device a native video image system
The visualization of the glottic structures through the SaCoVLM™ imaging system is graded as follows: Grade1: Visibility of the lateral portion of the right epiglottic fold and part of the laryngeal inlet. Grade 2: Visibility of both epiglottic folds and part of the laryngeal inlet. Grade 3: Visibility of the laryngeal inlet and part of the vocal cords. Grade 4: Visibility of the entire vocal cords. - Device Fiberoptic bronchoscope
The position of the i-Gel is checked using a fiberoptic endoscope
Primary outcome measures
- glottic visualization grades by fiberoptic exam assessment [Time frame: From anesthesia induction to the end of surgery]
Secondary outcome measures (1)
- Intra-operative effectiveness [Time frame: From anesthesia induction to the end of surgery]
