Stimulating Catheter for Lumbar Plexus Block: Better Postoperative Analgesia?

Phase 4
Completed
Conditions
Hip Replacement Arthroplasty
Interventions
Procedure: Spinal Anesthesia
Procedure: Local anesthetic infusion
Procedure: Intravenous analgesia
Procedure: Opioids rescue analgesia
Device: Stimulong, Pajunk, Germany.
Registration Number
NCT02162121
Lead Sponsor
ASST Gaetano Pini-CTO
Brief Summary

Stimulating catheters have been introduced to reduce the incidence of secondary failure after continuous peripheral nerve blocks, but they effectiveness over traditional nonstimulating catheters is still controversial. The aim of this prospective, randomized, blinded study is to detect if stimulating catheters improve postoperative compared with conventional non-stimulating catheters.
