New pain block may cut opioid use after breast surgery
NCT ID NCT03599635
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a longer-lasting pain medicine (liposomal bupivacaine) given as a nerve block before breast surgery could reduce the need for opioid painkillers after surgery compared to the standard medicine (bupivacaine). 112 adults having partial mastectomy took part. The goal was to see if the newer medicine provides better pain control and lowers opioid use.
