Transversus Abdominis Plane Blocks in Laparoscopic Colorectal Surgery: Better Pain Control and Patient Outcomes with Liposomal Bupivacaine than Bupivacaine.

Transversus abdominis plane (TAP) blocks are a safe and effective way to provide immediate postoperative pain relief in surgical patients, and have been shown to decrease narcotic requirements. Concerns about complications of narcotics, increase in hospital length of stay (LOS), and health-care costs make this of particular interest. We compared standard bupivacaine TAP blocks with those carried out using liposomal bupivacaine to evaluate postoperative outcomes.
