The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Collaborator:

Information provided by (Responsible Party):
University of Louisville
  Purpose
The investigators hypothesize that patients who receive a femoral catheter with low dose epidural Depodur will experience comparable or superior pain relief than those who receive both femoral and sciatic catheters. In addition, the investigators hypothesize that the one catheter will be less time consuming to place and facilitate early ambulation of the patient.

Condition Intervention Phase
Arthroplasty, Replacement, Knee Drug: Depodur Procedure: sciatic nerve block Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Investigator)
Primary Purpose: Treatment
Official Title: Comparison of Peripheral Nerve Blocks vs. Combination of Peripheral Nerve Block and DepoDur in Total Knee Joint Replacement: A Prospective, Randomized Study

Primary Outcome Measures:
  • Postoperative Pain [ Time Frame: 48 hours ]
    Pain as reported on a verbal rating scale ( VRS) (0-10, 0 = no pain, 10 = worse pain imaginable).


Enrollment: 75
Study Start Date: December 2009
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Peripheral Nerve group
Group will receive sciatic catheter placed before or after surgery by subgluteal approach with the use of ultrasound. The ischial tuberosity will be identified with the ultrasound probe and its midpoint marked. A catheter will be inserted and placed perineurally. If placed preoperatively, the catheter will be flushed with normal saline or 5% dextrose and will not be dosed until after surgery. After the patient is in the PACU and the surgeons have verified the sciatic nerve function, the sciatic catheter will be dosed with 35 mL 0.25% ropivacaine.
Procedure: sciatic nerve block
The sciatic nerve will be identified at the subgluteal level with ultrasound. A point 3 cm lateral and 4 cm caudad will be marked. Patients will be placed in the lateral position. A 18 G Tuohy needle will be inserted at a 45° angle until a peroneal or tibial twitch is obtained at 1.5 mA. Once the current can be reduced to obtain a twitch less than 0.5 mA, a catheter will be inserted and placed perineurally. If placed preoperatively, the catheter will be flushed with normal saline or 5% dextrose and will not be dosed until after surgery. After the patient is in the PACU and the surgeons have verified the sciatic nerve function, the sciatic catheter will be dosed with 35 mL 0.25% ropivacaine.
Other Name: Nerve block, sciatic
Experimental: Depodur Group
patients will have an L2-L3 epidural placed while they are in the sitting position before or after femoral catheter placement. They will receive 7.5 mg Depodur via the epidural catheter. All of these patients will receive Singular 10 mg and Claritin 10 mg before the epidural Depodur is placed, as per our protocol of patients receiving EREM.
Drug: Depodur
7.5 mg Depodur via the epidural catheter
Other Name: morphine sulfate extended-release liposome injection
