Could a simple injection cut Post-Surgery pain?
NCT ID NCT05953766
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether injecting a numbing medicine (ropivacaine) near a nerve in the pelvis can reduce pain after a hysterectomy done through small incisions. Sixty women will be randomly assigned to get either the real injection or a sham (fake) injection. Their pain levels will be measured over the first week after surgery to see if the nerve block helps.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ropivacaine (Naropin)
- What this could lead to
- If it works, this could offer a simple way to reduce pain after hysterectomy without strong opioids.
- What could go wrong
- This is a small, early-phase trial with only 60 participants. The nerve block may not provide meaningful pain relief, and results may not apply to all patients.
