First-pass success in video laryngoscopy with transcutaneous infrared illumination in patients with normal airways–a clinical pilot study
An erratum to this article was published (J Clin Monit Comput, 5 Oct 2026 ↗)
Authors' conclusion
The IRRIS device effectively illuminated the laryngeal inlet, enhancing differentiation from surrounding structures, such as the esophagus.
Study context
- Population
- Patients with normal airways undergoing endotracheal intubation by video laryngoscopy
- Participants
- 30 patients
- Comparison
- Video laryngoscopy with vs without IRRIS
- Primary endpoint
- First-pass success
Methodological detailspilot
- Pilot
Primary result
As reported in the abstract
- Successful intubation on the first attempt in both groups
Secondary outcomes
Glottic visibility (percentages of glottic opening (POGO) and glottic entrance visibility)
- Nearly identical in both groups
- Vocal cords not visible without IRRIS in the most obese patient
Intubation time and external manipulation
- Slightly longer intubation time and more instances of required external manipulation in the IRRIS group
