Summary

This study looks at whether ultrasound can reliably measure how much is in a child's stomach before surgery, which could help prevent rare but serious complications like breathing in stomach contents. About 60 children aged 2 to 18 will have stomach ultrasounds, and some will also take a Tylenol test to compare results. The goal is to see if ultrasound is a dependable tool for doctors to use.
