Can ultrasound predict aspiration danger in obese surgery patients?

This study looked at 60 obese adults scheduled for weight-loss surgery. Doctors used an ultrasound before surgery to measure how much food or liquid was still in the stomach, even after fasting. The goal was to see if a higher body mass index (BMI) or longer fasting time was linked to more stomach contents and a higher risk of breathing in stomach fluids during anesthesia. The findings could help create safer fasting guidelines for people with obesity.
