Brief summary

This study is designed to compare the standard of care against EXPAREL (bupivacaine liposome extended-release injectable suspension) to determine if total opioid consumption is reduced when using EXPAREL therefore possibly reducing total hospitalization costs.

Detailed description

This is a phase 4, prospective, sequential, open-label study designed to evaluate the efficacy, safety, and health economic benefits of intraoperative local wound infiltration with EXPAREL (bupivacaine liposome extended-release injectable suspension) compared with postsurgical administration of standardized intravenous (IV) morphine sulfate for postsurgical analgesia in adult patients undergoing open colectomy with general anesthesia.

Interventions

DRUGmorphine sulfate

Patients in this group will receive IV morphine sulfate (or Sponsor-approved equivalent) via patient-controlled analgesia (PCA) pump, as needed. The PCA pump will be set up postsurgically as soon as possible and prior to the patient leaving the post-anesthesia care unit (PACU) or immediately upon transfer to the floor if the stay in the PACU is less than 1 hour. All morphine sulfate (Group 1) patients will receive the same opioid in their PCA pump.

DRUGbupivacaine liposome extended-release injectable suspension

Patients in this group will receive 266 mg EXPAREL diluted with preservative free 0.9% normal saline to a total volume of 30 cc and administered via wound infiltration prior to wound closure. When not contraindicated, 30 mg IV ketorolac will be given at the end of surgery. If not indicated, an IV non-steroidal anti-inflammatory drug (NSAID) may be substituted per the site's standard of care. All patients will be offered rescue analgesia, as needed.

Inclusion criteria

* Male or female, 18 years of age and older. * Patients scheduled to undergo open segmental colectomy with planned primary anastamosis, as defined by cecectomy, right hemicolectomy, resection of transverse colon, left hemicolectomy, or sigmoidectomy. * Ability to provide informed consent, adhere to study visit schedule, and complete all study assessments.

Exclusion criteria

* Patients with a history of hypersensitivity or idiosyncratic reactions or intolerance to any local anesthetic, opioid, or propofol. * Patients who abuse alcohol or other drug substance. * Patients with severe hepatic impairment. * Patients currently pregnant or who may become pregnant during the course of the study. * Patients with any psychiatric psychological, or other condition that the Investigator feels may make the patient an inappropriate candidate for this clinical study. * Patients who have participated in a EXPAREL study within the last 30 days. * Patients who have received any investigational drug within 30 days prior to study drug administration, or planned administration of another investigational product or procedure during the patient's participation in this study. In addition, the patient will be ineligible if he or she meets the following criteria during surgery: * Patients with unplanned multiple segmental resections of large intestine. * Patients who have unplanned, temporary or permanent colostomies, ileostomies, or the like placed. * Patients who receive intraoperative administration of opioids (other than fentanyl or analogs) or any other analgesic, local anesthetics, or anti-inflammatory agents. * Patients who receive Entereg(R). * Patients who undergo any concurrent surgical procedure during the ileostomy reversal surgery.
