Summary

This study uses ultrasound to measure stomach fluid volume in healthy adults after drinking clear fluids, aiming to find safe limits for pre-surgery hydration. Ten participants who have fasted will drink a set amount of clear liquid, and researchers will track how much remains in the stomach over time. The goal is to improve fasting guidelines so patients can stay hydrated without increasing surgical risk.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could lead to clearer guidelines on how much and how close to surgery patients can safely drink clear fluids.
What could go wrong: This is a very small study (10 people) and only looks at healthy adults, so results may not apply to everyone or change practice directly.
