研究概览
简要总结
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.
详细描述
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.

- 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)
