Brief summary
The aim of this study is to compare the EzVision® videoryngoscope with conventional laryngoscopy using a Macintosh blade in patients with suspected difficult intubation. This study primarily aims to test the hypothesis that laryngoscopy image is better with EzVision® videoryngoscopy compared to direct laryngoscopy. The secondary hypothesis is also to test the view that, compared to direct laryngoscopy, EzVision® videolingoscopy will improve intubation success, reduce intubation attempts, shorten intubation time, facilitate intubation, and cause less additional complications such as bleeding or sore throat.
Interventions
Patient will be intubated with EzVision® videolaryngoscopy
Patient will be intubated with Macintosh Blade

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Glottis viewing | Approximately 1 year | Glottical viewing will be measured by Modified Cormack Lehane grading. In this scoring system, number 1 indicates the best appearance, while number 4 indicates the worst situation where the glottis is not visible. This measurement have no specific value, but it evaluates glottis opening as visually. 1\. Fill view of the glottis 2a. Partial view of the glottis 2b. Arytenoids or posterior part of the vocal cords only visible 3. Only epiglottis visible 4. Neither glottis nor epiglottis visible |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Attempted intubation | Approximately 1 year | Attempted intubation: defined as inserting the endotracheal tube into the oral cavity to perform endotracheal intubation (Wang HE, Garza AG) |
| Intubation time | Approximately 1 year | Intubation time: defined as the time between insertion of the laryngoscope into the oral cavity and the first appearance of end-tidal CO2. Ease of intubation: defined as the anesthetist's subjective assessment after finishing the intubation procedure as: (1) very easy; (2) easy; (3) medium; (4) difficult; and (5) impossible. (Ruetzler K) to. |
| Intubation failure | Approximately 1 year | Intubation failure: It is defined as intubation failure if one of the following occurs: * Failure to intubate despite three intubation attempts, * Situation that requires replacement of the intubation device, * Difficulty with intubation that will stop working at the discretion of the anesthesiologist |
| Ease of intubation | Approximately 1 year | Ease of intubation: defined as the anesthetist's subjective assessment after finishing the intubation procedure as: (1) very easy; (2) easy; (3) medium; (4) difficult; and (5) impossible. (Ruetzler K) |
