Nerve block volume may cut opioid use after hysterectomy
NCT ID NCT07533760
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether using different amounts of numbing medicine in a back muscle injection (erector spinae plane block) could reduce pain and the need for morphine after a hysterectomy. 80 women having the surgery took part. The goal was to find the best volume for safer, more effective pain control.
