Ultrasound and bite test for breathing tube placement in obesity
This study tests whether combining an ultrasound of the neck with a simple bite test can help doctors predict if a breathing tube will be hard to place in people with obesity. If you are scheduled for surgery with general anesthesia, this study may help improve your safety.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- Your body mass index (BMI) is 30 or higher.
- You are scheduled for surgery that requires general anesthesia (being put to sleep) and a breathing tube.
- You are generally healthy or have mild to moderate health conditions (classified as ASA II–III).
- You can cooperate and follow instructions, including performing the upper lip bite test.
- You have normal teeth (upper and lower front teeth present).
