Nerve block may ease broken rib pain in emergency care
NCT ID NCT07494851
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a nerve block called an erector spinae plane (ESP) block is practical to use in trauma patients with broken ribs. It included 27 adults with rib fractures and moderate to severe pain. The goal was to see if a larger trial is possible, not to prove the block works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ESP block (nerve block procedure)
- What this could lead to
- If successful, this could lead to a larger trial testing whether ESP blocks provide better pain relief for rib fractures than standard care alone.
- What could go wrong
- This is a very small feasibility study (27 participants) focused on recruitment and retention, not on proving pain relief. The results may not apply to all trauma patients.
