Subjects recruited into the study will undergo surgery as scheduled. During the procedure they will receive a TAP Block with one of the pain medications. TAP Block in the experimental arm will be performed with 20 mL (266mg) of liposomal bupivacaine with 25 mL (5 mg/mL) of bupivacaine diluted in 55 mL of normal saline. The control arm will have a TAP Block performed with 30 mL (5mg/mL) of bupivacaine diluted in 70 mL of normal saline. These doses are consistent with prior studies of TAP Block with liposomal bupivacaine. Subjects will be monitored for pain as per standard of care and will be given pain medication as needed.
