Which nerve block eases C-Section pain best? new trial aims to find out
NCT ID NCT07292662
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two ultrasound-guided pain relief injections—TAP block and ESP block—for women having a planned cesarean section. Both use the same local anesthetic (ropivacaine) to numb nerves, but they target different areas. The main goal is to see which provides better pain control at rest six hours after surgery. Researchers will also track pain at later times, opioid use, and how quickly women can walk and start breastfeeding.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ropivacaine
- What this could lead to
- If one block proves better, it could improve pain control and reduce opioid use after cesarean delivery.
- What could go wrong
- This is a small, early-stage study (90 participants) comparing two established techniques, so differences may be small or not clinically meaningful.
