Change in management of predicted difficult airways following introduction of video laryngoscopes

Figure 1 Awake fiberoptic intubation rate in the pre- video laryngoscope group and post video group. P value calculated with Fisher’s exact test. VL: Video laryngoscope; FOI: Fiberoptic intubation.

Figure 2 Change in intubation method of predicted difficult airways before and after introduction of video laryngoscopes. P value calculated with χ² test of equal proportion. VL: Vodeo laryngoscope; FOI: Fiberoptic intubation; DL: Direct laryngoscopy.
