New long-lasting shot may replace catheter for shoulder surgery pain

This study tested two methods of pain relief after shoulder fracture surgery: a single injection of a long-acting drug (liposomal bupivacaine) versus a continuous drip of standard painkiller through a small tube. 78 adults aged 18-80 who had shoulder fracture repair took part. The goal was to see if the single injection works as well as the continuous drip, which can have complications like tube blockage or infection.
