Brief summary
Intrabronal intubation is one of the basic methods of airway protection during cardiac surgery. The use of double-lumen tubes in the implementation of a standard method based on macintosh laryngoscope may cause the prolongation of the procedure especially in the case of difficult airways. The aim of the study was to match the effectiveness of endotracheal intubation using a standard Macontosh laryngskop and a normal double-lumen tube versus the ETView DL tube.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| intubation time | 1 day | from taking of the intubation device to successful intubation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| success of the first intubation trial | 1 day | effectiveness of the first attempt of intubation by participants using four intubation devices |
| overall success rate | 1 day | effectiveness measured during a maximum of three intubation attempts, confirmed by a single lung ventilation test |
| time to visualize the glottis | 1 day | time defined as the time from taking laryngoscope in hand until you obtain visualize the glottis |
| Cormack - Lehane grade | 1 day | self-reported percentage the vocal cord visualization using the Cormack-Lehane grading (grade 1-4) |
| ease of use | 1 day | To access subjective opinions about the difficulty of the each intubation method, participants were asked to give a rating on a visual analogue scale (VAS) with a score from 1 (extremely easy) to 100 (extremely difficult). |
| the degree of visibility of the glottis | 1 day | The POGO score describes how much glottic opening is visible. A POGO score of 100% indicates visualization of the entire glottic opening from the anterior commissure of the vocal cords to the interarytenoid notch. A POGO score of 0% corresponds with no visualization of laryngeal structures. |
