NCT01848951

Brief Summary

This study will compare the infiltrative transversusabdominis plane (TAP) block with liposomal bupivacaine to epidural analgesia (EA) in major abdominal surgery . The efficacy of the TAP block for abdominal surgery is well documented in literature, but there are no studies utilizing long-acting bupivacaine. The investigators believe the study will demonstrate no difference between the two in terms of pain scores and opioid consumption, but TAP blocks will decreased costs, urinary retention, and hypotension.

Outcome Measures

Primary Outcomes (2)

  • Pain scores

    Comparison of pain scores (0 = no pain to 10 = worst pain possible)

    96 hours post-op

  • Opioid Consumption in a 24-Hour period

    A comparison of opioid consumption in a 24-Hour period at 96 hours post-op between the interventions

    96 hours post-op

Secondary Outcomes (3)

  • Comparison of 96-hour hospital stay costs

    96 hours post-op

  • Comparison of urinary failure/catheter acquired infection rates

    96 hours post-op

  • Comparison of hypotension rates

    96 hours post-op

Study Arms (2)

Epidural

The skin will be disinfected with 2% chlorhexidine. Under sterile technique, the epidural will be placed. Epidural catheter will be placed at thoracic vertebral levels T5 to T10. Level chosen as clinically indicated. The epidural solution should contain institution's standard solution of Bupivicaine 0.05% and hydromorphone 10 mcg/cc. However, solution type should be clinically indicated.

Drug: Epidural

TAP Block

The skin will be disinfected with 2% chlorhexidine. The bilateral dual TAP infiltrative blocks will be placed using high-frequency ultrasound. The TAP blocks will be performed using lipospheric bupivacaine (Exparel) with the following dosing regimen.A 266mg (20cc) vial of lipospheric bupivacaine will be equally into 2 30 ml syringes using strict sterile technique. The solution will be diluted in each syringe with 20cc preservative free sterile 0.9% normal saline to a total volume of 30 ml in each syringe. Once the transversus abdominal plane is identified then a 5-10 ml of plain 0.9% normal saline will be injected to open the fascial plane. Once the plane is opened then the 15cc of diluted lipospheric bupivacaine will be administered under direct ultrasound visualization in all 4 TAP quadrants (subcostal position x2 and lateral position x2)
