  Purpose

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.

Further study details as provided by University of California, San Diego:

Primary Outcome Measures:
  • Patient's mean pain score (NRS) during perineural infusion as measured by the nursing staff at UCSD and entered in the computer system. [ Time Frame: 24 hours beginning 7:30am day following surgery ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Analgesic used, as reported by nursing staff in the UCSD computer system. [ Time Frame: 3 days following surgery ] [ Designated as safety issue: No ]
  • Patient's ambulation distance as recorded by therapist (occupational or physical) in the UCSD computer system. [ Time Frame: 3 days following surgery ] [ Designated as safety issue: No ]
  • Hip flexion, in degrees measured with a standard goneometer, as recorded by therapist (occupational or physical) in the UCSD computer system. [ Time Frame: 3 days following surgery ] [ Designated as safety issue: No ]
  • Infusion duration of pain pump, measured on the pump itself in hours and minutes. [ Time Frame: 3 days following surgery ] [ Designated as safety issue: No ]
  • Duration of hospital stay, in hours, as reported in the UCSD computer system. [ Time Frame: 3 days following surgery ] [ Designated as safety issue: No ]
  • Surgical/anesthetic adverse events as reported by hospital staff [ Time Frame: day of surgery and 3 days following ] [ Designated as safety issue: No ]
  • Experiences of patient during the infusion and following, as reported to study staff in a phone conversation, one week following surgery. [ Time Frame: 1 week following surgery ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: 1. Femoral Nerve Block
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
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.
Active Comparator: 2. Psoas Compartment Catheter
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
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.

Detailed Description:

To determine the association between perineural catheter location and postoperative analgesia, analgesic requirements, ambulatory distance, and flexion following hip arthroplasty.

Primary Hypothesis: Differing the catheter insertion site (femoral vs. psoas compartment) for a perineural local anesthetic infusion is not associated with lower pain scores during the 24-hour period beginning the morning following hip arthroplasty.
