Use of Exparel for Postoperative Analgesia Following Bariatric Surgery

The aim of this study is to evaluate the efficacy of liposomal bupivicaine in post operative analgesia for patients undergoing bariatric surgery when compared to conventional local analgesia. Patients will be randomly selected to receive either liposomal bupivicaine or conventional bupivicaine via a transversus abdominal plane block during surgery. Patients will be followed post-operatively to assess use of narcotics, post-operative pain and nausea scores, and length of stay.
