Summary

This study looked at 90 pregnant women having planned C-sections to see if the length of time they fasted before surgery changed their stomach volume. Researchers used ultrasound to measure stomach size and checked for nausea and vomiting after surgery. The goal was to find better fasting guidelines to improve safety and comfort.

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 help doctors give better fasting guidelines to reduce nausea and vomiting after C-sections.
What could go wrong
This is a small, completed observational study, not a treatment trial. Results may not apply to all pregnant women or hospital settings.
