Can a simple drug stop nausea during emergency C-Sections?
NCT ID NCT07740577
First seen Jul 31, 2026 · Last updated Aug 19, 2026 · Updated 2 times
Summary
This trial tests whether giving a preventive anti-nausea drug before an emergency cesarean section under spinal anesthesia can reduce nausea, retching, or vomiting during surgery. It focuses on women who have not fasted, which may increase the risk of these symptoms. The study compares two common medications, ondansetron and metoclopramide, to see which works better. The goal is to improve comfort and safety for mothers during this procedure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ondansetron and metoclopramide
- What this could lead to
- If effective, this could help standardize antiemetic use during emergency cesareans, improving maternal comfort and reducing complications.
- What could go wrong
- The trial is relatively small and focuses on a specific population, so results may not apply broadly. Both drugs have known side effects, and the study is not designed to prove long-term benefits.
