Newer nerve block may offer safer pain relief for broken ribs
NCT ID NCT06757803
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two pain-blocking injections for people with multiple broken ribs. One method (paravertebral block) is effective but risky; the newer retrolaminar block may be safer and easier. Sixty adults with rib fractures received one of the two blocks, and researchers measured how much extra pain medicine they needed in the first 48 hours.
