First seen Nov 01, 2025 · Last updated May 22, 2026 · Updated 34 times
Summary
This study looked at whether ultrasound can accurately detect a full stomach in patients lying flat versus sitting up at a 45-degree angle. The goal is to improve safety before anesthesia by better identifying those at risk for a rare but serious complication where stomach contents enter the lungs. Twenty-one healthy adults participated, and researchers compared ultrasound results in both positions.
