Back block breakthrough: less painkiller needed during spine surgery?
NCT ID NCT06303557
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a nerve block (ESPB) given before lumbar spine surgery can lower the amount of strong pain medicine (remifentanil) needed during the operation. 60 adults having elective back surgery took part. The goal was to see if the block provides better pain control and more stable vital signs during surgery.
