Overview
Brief Summary
A difficult tracheal intubation can be a problem, even if one has taken all precautions. A possible solution can be using a videolaryngoscope in conjunct with the Bonfils® intubation scope. As such, the videolaryngoscope can be used to achieve the best possible view and space of the laryngeal inlet for the insertion and manoeuvring of the Bonfils® intubation scope.
Detailed Description
In this blinded, unrandomised trial the investigators would like to investigate the change in Cormack and Lehane grade when using both videolaryngoscope (Macintosh videolaryngoscope, Karl Storz, Tuttlingen, Germany) and Bonfils® (Karl Storz, Tuttlingen, Germany). They also want to record the success of intubation and the time needed until successful endotracheal intubation when using this technique as well as complications (trauma to the oral cavity, dental trauma, and regurgitation seen by the anaesthesiologist) that may occur. Also saturation (SpO2) at the end of the procedure will be noted and adjuncts that are used.

- •One or more predictors of a difficult intubation:
- •restricted neck movement
- •thyromental distance \< 60 mm
- •interincisor/interdental distance \< 30mm
- •BMI \> 35 kg.m-2 Elective surgery making endotracheal intubation necessary (other than head and/or neck surgery) Fasted (≥ 6 hours)

Outcomes
Primary Outcomes
Cormack and Lehane grade achieved when using the combination technique compared with the Cormack and Lehane grade achieved earlier when using the Macintosh (video)laryngoscope alone.
Time Frame: The patients will be followed during induction of anesthesia, an average of 10 minutes
The operator will score these grades during the process of intubation. Pictures will be taken of the first and the second Cormack and Lehane grade, and these pictures will later be scored by two anaesthesiologists, blinded for the technique used (videolaryngoscopy alone or videolaryngoscopy combined with the Bonfils®).
Secondary Outcomes
- Proportion of successful intubation with the 2 methods under study, without the use of adjuncts.(The patients will be followed during induction of anesthesia, an average of 10 minutes)
- Time until successful endotracheal intubation(The patients will be followed during induction of anesthesia, an average of maximal 3 minutes)
- Complications rendered on during the procedure(The patients will be followed during induction of anesthesia, an average of 10 minutes)
- Adjuncts being used(The patients will be followed during induction of anesthesia, an average of 10 minutes)
