Airway Scope vs GlideScope for intubation in patients with BMI 40 or higher
Official title: Comparison of GlideScope and Airway Scope for Intubating Morbidly Obese Patients: A Randomized Controlled Study
Run by University of New Mexico · NCT07453563 · Data updated 2026-11-12
This study tests whether the Airway Scope or GlideScope makes intubation quicker and easier in adults with BMI 40 or more undergoing anesthesia.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18) with BMI ≥40 who are scheduled for surgery under general anesthesia.
✕Probably not a fit
Patients with pregnancy, congenital airway anomalies, prior major neck surgery or tracheostomy, significant lung or heart disease, or prisoners may not benefit from this study.

What this trial studies
This randomized trial compares two video laryngoscope devices—Airway Scope and GlideScope—during endotracheal intubation in adults with BMI ≥40. Outcomes focus on time to complete intubation, number of attempts, and oxygen saturation metrics during the procedure. Participants are adults scheduled for general anesthesia and are treated by attending anesthesiologists or residents. The goal is to determine which device provides a smoother intubation in a high BMI population where airway management is more challenging.
Why it matters
Potential benefit: If successful, the study could identify a device that reduces intubation time and maintains safer oxygen levels for very obese patients.
How similar studies have gone: Prior work in airway management with video laryngoscopes shows mixed results; this study adds direct comparison in the extremely obese group and its findings will clarify applicability.
