Summary
This study compares a low volume of the painkiller bupivacaine to the standard volume for a nerve block after gallbladder surgery. The goal is to see if the lower dose controls pain just as well while reducing the risk of side effects. About 96 adults having planned gallbladder surgery will take part.
