Femoral Versus Psoas Continuous Peripheral Nerve Blocks Following Hip Arthroplasty

23. september 2010 opdateret af: University of California, San Diego
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.

Detaljeret beskrivelse

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.

Deltagergruppe / Arm
Intervention / Behandling
Aktiv komparator: 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.
Aktiv komparator: 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
