Summary

This study looks at whether using ultrasound to measure the tongue, neck, and throat can better predict when a patient will have a difficult airway during surgery, compared to standard physical exams. About 200 adults having planned surgery under general anesthesia will take part. The goal is to see if ultrasound can help doctors prepare more effectively, potentially reducing risks.
