Figure 3

Visual analog scale for simulated tracheal intubation with and without gum-elastic bougie. (a) Laryngoscopic imaging and (b) tube passage through the glottis. White box: without GEB; black box: with GEB. Results are expressed as mean SD and were analyzed by two-way analysis of variance. NS: no significant difference; compared to without GEB.
