Brief summary
This study aims to compare the ORION video laryngoscope with the King Vision video laryngoscope for orotracheal intubation in patients without predictors of difficult airway scheduled for elective surgery under general anesthesia.
Detailed description
The video laryngoscope, compared to direct laryngoscopy, provides better visualization of the laryngeal and glottic structures, a higher success rate for intubation on the first attempt, and a lower incidence of complications such as mucosal injury, dental injury, and esophageal intubations. Despite the advantages offered by video laryngoscopy, its use is not widespread in developing countries due to high costs. For this reason, the ORION video laryngoscope was developed as a low-cost, reusable device that can undergo high-level disinfection. It is designed using additive manufacturing and meets the standards for biocompatibility, rigidity, and resistance. Additionally, it has undergone preclinical testing in simulation models where anesthesiologists have approved its use in real clinical scenarios. In this study, patients scheduled for elective surgery under general anesthesia without predictors of difficult airway will be included and randomized to be intubated with either the ORION video laryngoscope or the King Vision video laryngoscope. The study will compare the success of intubation on the first attempt, the time taken for intubation, the level of visualization of the glottic structures, and the associated complications between the two video laryngoscopes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Successful first attempt | After the endotracheal intubation completed | Measurement of orotracheal intubations obtained in the first attempt of videolaryngoscopy with the two videolaryngoscopes, successful orotracheal intubation will be corroborated by capnography. Measured in percentage (%). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Laryngeal visualisation measured with the Cormack Lehane scale | After the endotracheal intubation completed | Measurement of visualization of glottic structures using the Cormack Lehane scale in grade I, II, II and IV obtained with both video laryngoscopes. Measured in percentage (%). |
| Laryngeal visualisation measured with the POGO scale | After the endotracheal intubation completed | Measurement of the visualization of the glottic structures using the POGO (Percentage of Glottic Opening) scale from 0% to 100% obtained with both video laryngoscopes. Measured in percentage (%). |
| Esophageal intubation | After the endotracheal intubation completed | Measurement of the number of esophageal intubations obtained with both video laryngoscopes. Measured in percentage (%) |
| Intubation time | After the endotracheal intubation completed | Time elapsed from the time the video laryngoscope blade crosses the dental arch until the orotracheal tube is inserted into the trachea, this time will be measured for each video laryngoscope. Measured in seconds (s). |
| Number of video laryngoscopy attempts | After the endotracheal intubation completed | Measurement of the number of video laryngoscopy attempts to successful intubation with both video laryngoscopes. Measurement in percentage (%) |
| Intubation failure | After the endotracheal intubation completed | Three videolaryngoscopies with duration of 120 seconds each without achieving orotracheal intubation. The number of intubation failures of both videolaryngoscopes will be measured in percentage (%). |
| Complications | After the endotracheal intubation completed | Measurement of complications (mucosal, lip, oral, pharyngeal and laryngeal injury, total or partial fracture of a tooth and Hypoxemia) that occur with the use of the ORION and King Vision Videolaryngoscopes. Measured in percent (%) |
