Body Roundness Index and BMI compared with the VIDIAC airway score in people with obesity
Evaluation of the Correlation Between Body Roundness Index (BRI), Body Mass Index (BMI), and VIDAC Score in Obese Patients: A Prospective Observational Study
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.

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.
Who should consider this trial
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.
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.
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 performed: 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.
