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.
