NCT00967980

Brief Summary

The purpose of this research study is to determine if the insertion site of a perineural catheter, or tiny tube placed next to the nerves that go to the hip which you will have surgery, affects the amount of pain relief that is experienced after surgery.

Outcome Measures

Primary Outcomes (1)

  • Patient's mean pain score (NRS) during perineural infusion as measured by the nursing staff at UCSD and entered in the computer system.

    24 hours beginning 7:30am day following surgery

Secondary Outcomes (7)

  • Analgesic used, as reported by nursing staff in the UCSD computer system.

    3 days following surgery

  • Patient's ambulation distance as recorded by therapist (occupational or physical) in the UCSD computer system.

    3 days following surgery

  • Hip flexion, in degrees measured with a standard goneometer, as recorded by therapist (occupational or physical) in the UCSD computer system.

    3 days following surgery

  • Infusion duration of pain pump, measured on the pump itself in hours and minutes.

    3 days following surgery

  • Duration of hospital stay, in hours, as reported in the UCSD computer system.

    3 days following surgery

  • +2 more secondary outcomes

Study Arms (2)

1. Femoral Nerve Block

ACTIVE COMPARATOR

Patients will be randomized with a computer program to receive a femoral catheter. The catheter will be placed using standard technique. The time of catheter placement will be recorded as well as the pain/discomfort of catheter placement as reported by the patient on a 0-10 scale where 0=no pain/discomfort and 10=worst imaginable pain/discomfort.

Procedure: Femoral Nerve Block vs. Psoas Compartment Nerve Block

2. Psoas Compartment Catheter

ACTIVE COMPARATOR

Patients will be randomized with a computer program to receive a psoas compartment catheter. The catheter will be placed using standard technique. The time of catheter placement will be recorded as well as the pain/discomfort of catheter placement as reported by the patient on a 0-10 scale where 0=no pain/discomfort and 10=worst imaginable pain/discomfort.

Procedure: Femoral Nerve Block vs. Psoas Compartment Nerve Block

Interventions

Patients, undergoing hip arthroplasty or hip resurfacing will be randomized to one of two groups: femoral nerve block or psoas compartment nerve block. Patients randomized to femoral nerve block will receive this block prior to surgery. Patients randomized to psoas compartment nerve block will receive this block prior to surgery. Both patients will receive Mepivicaine via catheter prior to surgery and following surgery, Ropivicaine via pain pump.
