Liposomal bupivacaine infiltration into the transversus abdominis plane for postsurgical analgesia in open abdominal umbilical hernia repair: results from a cohort of 13 patients.

Background: Achieving adequate control of postsurgical pain remains a challenge in patients undergoing abdominal surgery. Transversus abdominis plane (TAP) infiltration has been shown to provide postsurgical analgesia following lower abdominal surgery. We assessed the safety and efficacy of a prolonged-release liposomal formulation of the local anesthetic bupivacaine administered via infiltration into the TAP in a cohort of patients undergoing open abdominal umbilical hernia repair.
