Wound infusion of bupivacaine following radical retropubic prostatectomy: a randomised placebo-controlled clinical study.

Context: The effectiveness of postoperative analgesia through a wound catheter is subject to considerable debate.

Objective: To test the hypothesis that local wound infusion with bupivacaine followed by continuous infusion could reduce postoperative need for opioids in patients undergoing retropubic prostatectomy.

Design: Single-centre prospective, double-blinded, placebo-controlled trial.
