Preemptive Femoral & Lateral Femoral Cutaneous Nerve Blocks for THA Acute Pain

• Status: Terminated
• Trial end date: 2014-03-01
• Target enrollment: 0
• Participant gender: All

Summary

The goal of the study is to evaluate via a prospective, blinded, randomized clinical trial, whether ultrasound-guided single femoral and lateral femoral cutaneous nerve blocks with ropivacaine 0.5% with epinephrine (1:200,000) as a tracer for intravascular injection (total 30 ml) vs. saline with epinephrine (1:200,000) (total 30 ml), given just prior to same day elective hip arthroscopy, is effective in reducing acute postoperative pain (NRS scores), postoperative opiate consumption, and time to discharge from the postanesthesia care unit. Differences between groups with respect to postoperative quality of life and functional scores will also be evaluated.
