NCT ID NCT05435157
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 2 times
Summary
This study used ultrasound to measure how much fluid remains in the stomach after standard preoperative fasting in 592 adults scheduled for elective surgery. Researchers compared diabetic and non-diabetic patients to see if diabetes affects stomach emptying. The goal is to help tailor fasting guidelines for safer surgery.
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 better preoperative fasting guidelines for people with diabetes, reducing the risk of complications during surgery.
- What could go wrong
- This is an observational study, not a treatment trial. It only measures differences and does not test any intervention, so it cannot directly change practice.
