NCT02121392

Brief Summary

The purpose of this study is to further investigate the efficacy of adductor canal nerve blocks for pain management after total knee replacement. Specifically we are studying adductor canal nerve blocks in conjunction with epidural anesthesia, which is a combination that has not been extensively researched before. Our question is whether combining these modalities will enhance patient satisfaction after surgery and accelerate patients' readiness to discharge.

Study Arms (2)

Epidural Catheter without Adductor Canal Nerve Block Catheter

SHAM COMPARATOR

Patients randomized to the sham catheter will have a sham catheter placed on the skin and obscured with an opaque dressing and attached to a functional pump which will not be turned on.

Device: Adductor Canal Nerve Block Sham CatheterDrug: Bupivacaine

Epidural Catheter with Adductor Canal Nerve Block Catheter

EXPERIMENTAL

Patients will receive a continuous adductor canal block placed under ultrasound guidance under the supervision of an attending physician who is fellowship trained.

Device: Adductor Canal Nerve Block CatheterDrug: Bupivacaine

Interventions

ACNB catheter will be placed by anesthesia residents under the supervision of board-certified anesthesiologists familiar with regional anesthesia techniques, who are part of the anesthesia pain service. They will be performed at the bedside, aseptically, with the patient's vital signs monitored throughout the procedure. 1% lidocaine will be infiltrated in the skin and subcutaneous tissues overlying the adductor canal as visualized on ultrasound. Via a 17 gauge touhy needle a closed tip non-stimulating, epidural catheter will be placed after 1% lidocaine is used to hydrodissect the space lateral to the superficial femoral artery within the adductor canal. The catheter will be secured to the skin. All catheters will be connected to infusion pumps with opaque plastic bags covering the pumps. The functional ACNB pumps will run 8cc/h.

Epidural Catheter with Adductor Canal Nerve Block Catheter

Patients randomized to the sham catheter will have a chlorhexidine prep of the skin and ultrasound examination of the adductor canal on postoperative day #1. To minimize patient risk, a wooden applicator will be used to apply 10 seconds of pressure to the leg followed by catheter securing to the skin with the same tegaderm and paper tape dressing used on functional catheters. All catheters will be connected to infusion pumps with opaque plastic bags covering the pumps. The sham catheter pumps will not be turned on.

Epidural Catheter without Adductor Canal Nerve Block Catheter

In the functioning continuous adductor canal block, 0.125% bupivacaine will be infused at a rate of 8cc/hr.

Limitations and Caveats

Limitations included the number of patients withdrawn (n = 89) after randomization. The majority withdrew due to unsuccessful epidural catheterization (n = 34). Despite this, these patients were distributed evenly across the two groups.
