Body Roundness Index and BMI compared with the VIDIAC airway score in people with obesity
Official title: Evaluation of the Correlation Between Body Roundness Index (BRI), Body Mass Index (BMI), and VIDAC Score in Obese Patients: A Prospective Observational Study
Run by Samsun University · NCT07372846 · Data updated 2026-11-12
We will test whether Body Roundness Index (BRI) predicts airway visibility on videolaryngoscopy better than Body Mass Index (BMI) in adults with obesity having general anesthesia.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with obesity (BMI ≥30) scheduled for procedures under general anesthesia who can give informed consent and do not have the listed exclusion conditions.
✕Probably not a fit
Patients unlikely to benefit include non-obese individuals, pregnant patients, emergency surgery cases, or those with tracheostomies or major head and neck deformities.

What this trial studies
This is an observational, single-center study that measures Body Roundness Index, BMI, and other airway-related measurements and records the VIDIAC score during videolaryngoscopy in obese patients receiving general anesthesia. Eligible participants are adults with BMI ≥30 who consent to participation, while pregnant patients, emergency surgeries, those with head/neck deformities or tracheostomies, and those with severe instability are excluded. Investigators will compare correlations and use regression analyses to see whether BRI is a stronger predictor of glottic visibility and anatomical complexity than BMI. The study uses standard videolaryngoscopy during routine anesthesia care and does not add experimental interventions.
Why it matters
Potential benefit: If successful, this could give clinicians a better preoperative tool to predict difficult videolaryngoscopic views and help plan safer airway management for people with obesity.
How similar studies have gone: Previous work has linked BMI, neck circumference, and temporomandibular joint dysfunction to difficult airway management, but using BRI to predict VIDIAC scores is a novel, previously untested approach.
