The transversus abdominis plane (TAP) block can be used to reduce pain in patients who get abdominal surgery. TAP blocks are given with a local anesthetic. The purpose of this study is to compare pain medication usage after surgery between two different types of local anesthetic: liposomal bupivacaine and standard bupivacaine.
