简要总结
Videolaryngoscopes offer the potential to make tracheal intubation easier for the anaesthetist and less traumatic for the patient. This study aims to compare the intubation difficulty scores (a validated scoring system for ease of intubation) using the McGrath MAC as a videolaryngoscope, the McGrath MAC only as a direct laryngoscope (without video screen) and the MacIntosh laryngoscopes.

结局指标
主要结局
Intubation Difficulty Score
时间窗: 5 minutes
The Intubation Difficulty Scale (IDS) is a numerical score based on seven parameters. The scoring of each parameter represents a divergence from an 'ideal' condition and the total score represents a sum divergence from a zero difficulty ideal intubation. The seven parameters are number of supplementary attempts, number of supplementary operators, number and type of alternative techniques used, laryngoscopic grade, subjective lifting force, the use of external laryngeal manipulation and mobility or position of the vocal cords.
次要结局

- Perception of force used(5 minutes)
- Complications(5 minutes)
- Ease of intubation(5 minutes)
- Failure to intubate(5 minutes)
