A randomized, blinded, placebo-controlled, prospective clinical study to evaluate the effectiveness of a diluted liposomal-encapsulated bupivacaine suspension in dogs undergoing a ventral midline celiotomy.

Objective: To evaluate the effectiveness of a liposomal-encapsulated bupivacaine suspension (LEBS; Nocita), at a 1:5 dilution with 0.9% NaCl, for the reduction of postoperative pain scores and a related reduction in the need for postoperative opioids in dogs undergoing ventral midline celiotomy.

Hypothesis: When infused at a 1:5 dilution, LEBS results in less postoperative pain (as indicated by pain scale scores), and a reduction in postoperative opioids, in dogs undergoing ventral midline celiotomy.
