Summary

This study looked at whether giving metoclopramide before a planned C-section actually lowers stomach fluid, which is meant to prevent rare but serious aspiration during anesthesia. Researchers compared stomach volumes using ultrasound in 72 healthy women who received either the drug or a placebo. The goal is to see if the drug offers real benefit or just adds side effects, which could change future anesthesia guidelines.

What this could mean

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

Active substance
metoclopramide
What this could lead to
If results show metoclopramide doesn't help, guidelines may change to avoid unnecessary side effects in women having planned C-sections.
What could go wrong
This is a small, completed Phase 4 study (72 people) that may not apply to all patients or emergency C-sections. It tests a common drug, not a new breakthrough.
