Laparoscopic view of infiltration of liposome bupivacaine at 12-mm port site. (a) Insertion of needle into deep tissue layers. Advancement of needle is stopped just prior to penetration of the parietal peritoneum. (b) Infiltration of liposome bupivacaine and dispersion of fluid to form a wheal (outlined by white oval). This process was repeated in four quadrants around the site of the trocar to form a field block. Photographs courtesy of Peter M. Bertin, DO.
