Brief Summary

Despite the increasing use of patient-controlled anesthesia (PCA) for postoperative pain management, efforts are continuing to find effective methods to relieve pain after abdominal surgery. Although opioid is an effective analgesic it has opioid related adverse events (ORAEs). Bupivacaine should reduce postoperative pain but it has relatively shorter duration of action. Liposome bupivacaine (Exparel) has been approved as a single dose infiltration for longer postoperative period analgesic. It provides up to 72 hours analgesia postoperatively; results in lesser opioids usage and reduce the ORAEs. Transversus abdominis plane (TAP) block is a relatively new regional anesthetic technique. TAP blocks have been performed to reduce opioid use and control pain in several laparoscopic surgical procedures, including colorectal resections, cholecystectomy and bariatric surgery. The aim of this study is to study the opiate usage, pain and nausea post laparoscopic gastric bypass or sleeve gastrectomy using Exparel versus Bupivacaine as TAP block and port sites infiltration.

Outcome Measures

Primary Outcomes (1)

  • Total Amount of Opioids at 48 Hours

    The total amount of opioids used will be recorded from the nurse chart.

    At 48 hours post operative

Secondary Outcomes (2)

  • Cumulative Pain Score Through 48 Hours After Surgery

    Pain assessed when the patient is admitted to the recovery room after surgery, every 8 hrs thereafter for up to 48 hours post operatively

  • Cumulative Nausea Score

    Nausea assessed when the patient is admitted to the recovery room after surgery, every 8 hrs thereafter for up to 72 hours post operatively

Study Arms (2)

Experimental

EXPERIMENTAL

Patients at our Bariatric Surgery Center of Excellence fulfilling NIH criteria for bariatric surgery and planned operation of laparoscopic Roux-en Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) as primary bariatric procedure randomized to receive 20 ml of 1.3% Exparel + 30 ml of 0.5% Bupivacaine + 150 ml of Saline

Drug: ExparelDrug: BupivacainDrug: Saline

Control

ACTIVE COMPARATOR

Patients at our Bariatric Surgery Center of Excellence fulfilling NIH criteria for bariatric surgery and planned operation of laparoscopic Roux-en Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) as primary bariatric procedure randomized to receive 60ml of 0.5% Bupivacaine + 140 ml of Saline.

Drug: BupivacainDrug: Saline

Interventions

6 trocars are placed to perform LRYGB or LSG: two 12 mm trocars and four 5 mm trocars. Exparel will be injected at port sites.

Limitations and Caveats

There is no data available to guide us on the dosage of liposome bupivacaine in bariatric surgery. We assume adequate quantity and coverage of liposome bupivacaine (266mg) in this obese population, despite that they have a bigger surface area.
