This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
