Can a simple injection make hysteroscopy Pain-Free?
NCT ID NCT07178379
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether injecting a local anesthetic (mepivacaine) into the ligaments around the cervix can reduce pain during an outpatient hysteroscopy. About 70 women who have never had a hysteroscopy will be randomly assigned to receive either the anesthetic or a placebo. The main goal is to see if the anesthetic lowers pain scores on a standard scale.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Mepivacaine (local anesthetic)
- What this could lead to
- If it works, this could provide a simple, effective way to reduce pain during hysteroscopy, making the procedure more comfortable for many women.
- What could go wrong
- This is a small, early-stage trial. The placebo group receives a saline irrigation, not an injection, so blinding is imperfect. The results may not apply to all types of hysteroscopy.
