Bupivacaine Pain Pumps to Decrease Mastectomy Post-Operative Pain

NCT01494259 | Withdrawn Phase 4

Brief Summary

This double-blind, randomized, controlled clinical trial comparing patient-reported pain and pain medication/narcotic use between patients randomized to treatment (bupivacaine) or placebo (saline) delivered via pain pump to the mastectomy site. Candidates will have chosen to have a mastectomy on one side immediately followed with tissue expander placement breast reconstruction. Patients will be randomized 1:1 to bupivacaine- (treatment) or saline-(placebo) filled percutaneously-placed pain pumps; neither the participants nor the study staff will know participants' treatment. Data on patient-perceived pain and pain medication use will be collected before surgery, during surgery, and after surgery on Days 1, 2, 3, 7, and 90, and at Years 2 and 4 by phone. The investigators hypothesize that patients randomized to the treatment (bupivacaine) group will have significantly lower pain scores and use less pain medicine than patients who receive placebo during the first 90 days following their surgery. The Year 2 and Year 4 follow-ups are included as tertiary endpoints to capture differences in chronic pain, and patients will be asked to complete the same questionnaires as at the Day 90 follow up.

Outcome Measures

Primary Outcomes (1)

• Differences in post-operative static and moving pain scores between patients randomized either to bupivacaine- (treatment) or saline- (placebo) filled, percutaneously-placed pain pump analgesic administration for post-operative pain control.

  Post-operative pain, pain medication/narcotic use, and assessment for adverse events (AEs)/serious adverse events (SAEs) will be assessed the Day of surgery through post-operative Day 7. A clinic visit occurs on Day 7 when the pain pump will be removed and additional data collected (updated medical history, pain medication/narcotic use, AEs/SAEs, and study questionnaires).

  Day of Surgery through Day 7

Secondary Outcomes (3)

• Document long-term changes in QOL scores between patients randomized either to bupivacaine- (treatment) or saline- (placebo) filled, percutaneously-placed pain pump analgesic administration for post-operative pain control.

  Day 90

• Document long-term changes in QOL scores between patients randomized either to bupivacaine- (treatment) or saline- (placebo) filled, percutaneously-placed pain pump analgesic administration for post-operative pain control.

  Year 2

• Document long-term changes in QOL scores between patients randomized either to bupivacaine- (treatment) or saline- (placebo) filled, percutaneously-placed pain pump analgesic administration for post-operative pain control.

  Year 4

Study Arms (2)

Bupivacaine (Treatment) Group

EXPERIMENTAL

The Symbios GOPump is the Food and Drug Administration-approved delivery device used to infuse the bupivacaine. The pump is attached to catheters placed in the patient's breast reconstruction site. A 10cm long 16-guage needle is provided to aid insertion of the catheter into the patient. The entire catheter will pass through the bore of the introducer needle. A 60cc syringe is used to fill the Symbios GOPump through the fill port. After filling the 60cc syringe with up to 300cc of 0.5% bupivacaine, the syringe is attached to the port and the medication injected into the infusion pump. The steady-flow pressure regulator maintains a constant 6 psi pressure in the outflow chamber ensuring a uniform flow of medication through each catheter inserted into the Symbios GOPump.

Drug: Bupivacaine

Saline (Placebo) Group

PLACEBO COMPARATOR

The Symbios GOPump is the Food and Drug Administration-approved delivery device used to infuse the saline. The pump is attached to catheters placed in the patient's breast reconstruction site. A 10cm long 16-guage needle is provided to aid insertion of the catheter into the patient. The entire catheter will pass through the bore of the introducer needle. A 60cc syringe is used to fill the Symbios GOPump through the fill port. After filling the 60cc syringe with up to 300cc of normal saline, the syringe is attached to the port and the medication injected into the infusion pump. The steady-flow pressure regulator maintains a constant 6 psi pressure in the outflow chamber ensuring a uniform flow of medication through each catheter inserted into the Symbios GOPump.

Drug: Saline

Interventions

Bupivacaine DRUG

Up to 300cc of 0.5% bupivacaine administered to the mastectomy site via 2 catheters connected to the Symbios GOPump at a rate of 2 cc per hour per catheter over 3 days.

Also known as: Marcaine with epinephrine

Bupivacaine (Treatment) Group

Saline DRUG

Up to 300cc of normal saline administered to the mastectomy site via 2 catheters connected to the Symbios GOPump at a rate of 2 cc per hour per catheter over 3 days.

Also known as: Normal Saline

Saline (Placebo) Group
