Summary

This study looks at how different amounts of clear liquids (like water or juice) affect stomach contents in teens aged 13-17 before an upper GI endoscopy. Participants are randomly assigned to drink 3, 5, 7, or 10 ml of clear fluid per kilogram of body weight two hours before the procedure. The goal is to measure stomach volume and acidity to help improve fasting guidelines.

What this could mean

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

Active substance
clear oral fluid (water, pulp-free juice, tea or coffee without milk)
What this could lead to
If successful, this study could help create clearer guidelines on how much clear liquid is safe for teens to drink before procedures.
What could go wrong
This is an early-stage study with a small sample size, so results may not apply to all patients. It only looks at stomach volume and acidity, not directly at safety outcomes.
