Use of Exparel for Postoperative Analgesia Following Bariatric Surgery

Status Not yet recruiting

Clinical Trial Summary

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.

Clinical Trial Description

Optimizing pain management following bariatric surgery is an important aspect of patient care and post-surgical recovery. Despite advances in post-operative pain management, this remains a challenge and opioids continue to dominate as the most widely used analgesia for post-surgical pain management. Opioid use especially in the opioid-naive patient carries significant short term and long term risks including over dependence and chronic opioid use.

Movements towards minimizing post-operative opioid use has shown regional anesthetic techniques to be highly effective in the management of pain in surgical patients. More specifically, liposomal bupivicaine (Exparel) is a novel non-opioid local analgesia that takes advantage of a multi-vesicular liposomal system to provide extended analgesia release over 72-96 hours.

The purpose of this study to evaluate the use of liposomal bupivicaine in the management of post-operative pain following bariatric surgery via a transversus abdominis plane (TAP) block. Patients will be randomized to receiving either liposomal bupivicaine or traditional 0.25% bupivicaine locally infiltrated at the time of bariatric surgery. Both liposomal bupivicaine and traditional bupivicaine will be administered via TAP block after identification of planes via laparoscopy by the bariatric surgeon.

Patients will be followed post-operatively to assess use of opioid analgesia between the two arms. In addition, they will be assessed with respect to pain and nausea using analog scores, as well as hospital length of stay. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
