Femoral Versus Psoas Continuous Peripheral Nerve Blocks Following Hip Arthroplasty
Phase 4
Completed
- Conditions
- Hip ArthroplastyHip Pain
- Registration Number
- NCT00967980
- Lead Sponsor
- University of California, San Diego
- 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.
- 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.

- Primary Outcome Measures
Name Time Method 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 Outcome Measures
Name Time Method 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 Surgical/anesthetic adverse events as reported by hospital staff day of surgery and 3 days following Experiences of patient during the infusion and following, as reported to study staff in a phone conversation, one week following surgery. 1 week following surgery
