Brief summary
A randomized controlled prospective study of laryngoscopy and intubation success comparing direct laryngoscopy and the McGrath® Mac videolaryngoscope.
Detailed description
As airway management continues to evolve the investigators do not have an accurate statement of the success of direct laryngoscopy in daily clinical practice. The use of videolaryngoscopy is increasing as a technique for rescue intubation as well as for elective intubation. Current airway management guidelines recommend video-assisted laryngoscopy as a choice for basic airway management. This is a proposed comparison study of a video laryngoscope, use in the daily anesthesia practice, and its likely increased success compared to direct laryngoscopy. An international, multi-center, prospective randomized comparative trial (RCT) is proposed testing the superiority of oral tracheal intubation with the McGrath® MAC versus conventional laryngoscope in adult patients under general anesthesia.
Interventions
DEVICEthe McGrath MAC
in a randomised order we evaluate the success rate with the first attempt of the tracheal tube into the trachea.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| intubation success | at intubation; < 120 seconds | successful tracheal intubation at the first attempt, compared to more than one attempt |

|---|---|---|
| Cormack and Lehane Classification | < 120 seconds | after insert the instrument the user describe the view of the laryngeal structure |
| Percentage of glottic opening | < 120 seconds | airway visualization during intubation process |
| Number of attempts | < 120 seconds | after two attempts using defined rescue techniques (e.g. rigid stylet, laryngeal mask) |
| IDS (intubation difficult score) | < 120 seconds | intubation difficult score |
