The study aims to determine the better device to facilitate intubation in patients with a limited neck movement and small mouth opening. This may help anesthesiology as well as emergency medicine practitioners and departments to decide when choosing between these two conceptually similar device. The hypothesis to be tested is that the C-MAC® is more superior when compared to the Bonfils Intubation Fibrescope in success of intubation, time to intubation and complication rate in patients with a fixed cervical collar.

| Success of intubation on first attempt | A rigid cervical collar will to each patient to stimulate a difficult airway and standard induction of general anaesthesia will be carried out. Adequate muscle relaxation will be confirmed by the use of a standard neuromuscular Train-of-Four monitor, showing no twitch. Intubation will then proceed with the assigned airway device. A successful outcome at intubation will involve being able to pass an appropriately sized endotracheal tube pass the vocal cords into the trachea on the first try, as evidenced by the presence of end tidal carbon dioxide on a capnograph. | up to 10min - from time of induction to appearance of end tidal carbon dioxide on capnograph after first attempt at intubation |

| Time taken to successful intubation | A rigid cervical collar will to each patient to stimulate a difficult airway and standard induction of general anaesthesia will be carried out. Adequate muscle relaxation will be confirmed by the use of a standard neuromuscular Train-of-Four monitor, showing no twitch. Time to successful intubation will then be measured from the first handling of the airway device, until successful intubation with an endotracheal tube is confirmed by the presence of end tidal carbon dioxide on a capnograph trace. |
