Testing Ultrasound and Jaw Tests for Airway Difficulty in Obese Patients
This study tests two simple exams—ultrasound imaging and a jaw-bite test—to help doctors predict which obese patients may have difficulty with breathing tubes during surgery. The goal is to find safe, quick ways to identify airway challenges before anesthesia.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 to 65 years old and weigh enough to be classified as obese (BMI of 30 or higher)
- You are scheduled for elective (planned, non-emergency) surgery that requires general anesthesia and an endotracheal tube (breathing tube down your throat)
- You are in good enough health for surgery (ASA physical status II or III)
- You have healthy upper and lower front teeth and can move your lower jaw normally
- You have never had facial surgery, trauma, or jaw problems that limit your jaw movement
- You can follow simple instructions and agree to perform a jaw-bite test during the exam

This study looks at how neck size relates to airway management during surgery. It may help doctors prepare better for placing a breathing tube.
This study uses ultrasound to see the airway in children before surgery. It aims to predict if the child's airway will be easy or difficult to intubate (placing a breathing tube).
This trial uses ultrasound to measure children's airways before surgery, aiming to predict if placing a breathing tube will be difficult. It could help doctors prepare better and keep kids safer during anesthesia.
This study compares two methods—ultrasound imaging and physical examination—to predict whether anesthesia will be challenging in obese patients undergoing surgery. Understanding which method works better could help doctors prepare for safer anesthesia.
This trial studies whether using an ultrasound of the front of the neck can help doctors predict if a breathing tube will be difficult to place in patients who are overweight or obese. The goal is to improve safety during general anesthesia for planned surgeries.
This study compares two ways of checking the airway before surgery in people with obesity: a breathing tube placed with the help of ultrasound (a handheld device that uses sound waves) versus a standard laryngoscope (a lighted tool). The goal is to see which method is safer and easier for larger patients.
