Other Name: smaller sized GlideScope® videolaryngoscopy
- The Differences in the Glottis View (C&L Grade) of Macintosh Laryngoscope and GVL Selected by Weight. [ Time Frame: up to 1 day of surgery ]
Glottis view was scored using C&L grade by Macintosh laryngoscope and GVL selected by weight, and compared each other.
We used modified C&L grade: grade 1, all or most of the glottic aperture was visible; grade 2a, posterior cords and cartilage visible; grade 2b, only posterior cartilage visible; grade 3a, epiglottis visible and can be lifted; grade 3b, epiglottis adherent to the posterior pharynx; and grade 4, the epiglottis could not be visualized.
For the statistical analysis, the modified C&L grade was converted to an ordinal scale; grade 1 to 1, grade 2a to 2, grade 2b to 3, grade 3a to 4, grade 3b to 5, and grade 4 to 6. Therefore, score range for the data reported in the table was between 1 and 6, with 1 representing best view and 6 representing no view.
- The Differences in the Glottis View (C&L Grade) of GVL Selected by Weight and Smaller Sized GVL [ Time Frame: up to 1day of surgery ]
Glottis view was scored using C&L grade by GVL selected by weight and smaller sized GVL, and compared each other.
Score range for the data reported in the table was between 1 and 6, with 1 representing best view and 6 representing no view.
