Actual (reported)Liposomal bupivacaine (trade name Exparel) is a local analgesic that is designed to produce more long-term pain control. Bupivacaine, a widely used local analgesic, is stored within liposomes, which break down in soft tissue over time. Typical length of therapeutic effect for standard bupivacaine is up to 6 hours. The liposomal formulation of bupivacaine, however, has a length of therapeutic effect of up to 72 hours. Typical post-operative incisional pain is known to last for several days in most cases and is thought to peak between 1-2 days after surgery. Therefore, the benefit of most short-acting local analgesics does not overlap with the period of most need.

Actual (reported)Changed pain scores using liposomal bupivacaine day 1 post-operative
Using the 10 point pain scale, determine if liposomal bupivacaine use leads to changed pain scores on post-operative day 1 compared to standard analgesics after laparoscopic sleeve gastrectomy.
Day 1 post-operative
Changed pain scores liposomal bupivacaine days 0, 2,3 post-operative
Days 0, 2, 3 post-operative
Changed use of opioid medications post operative days 0-3
Post-operative days 0-3
