Table 2.
Detailed outcome data for all devices. The data are presented as the median and range.
| C-MAC (n = 23) | TruView (n = 22) | Macintosh (n = 20) | p-value | |
| CL I | 19 | 21 | 17 | n.s. |
| CL II | 3 | 1 | 2 | n.s. |
| CL III | 1 | - | 1 | n.s. |
| CL IV | - | - | - | n.s. |
| TTI (sec) | 28 (8-93) | 52* (20-102) | 26 (18-95) | *p<0.05 vs. C-MAC and Macintosh |
| LpO2 (%) | 99 (94-100) | 100 (86-100) | 100 (93-100) | n.s. |
| VAS (cm) | 9 (8-10) | 8* (6-10) | 9 (0-10) | *p<0.05 vs. C-MAC and Macintosh |
CL = Cormack & Lehane grade; TTI = Time to intubation; LpO2 = Lowest peripheral oxygen saturation; VAS = Visual analog scale.
