Randomized Controlled Trial Clinical TrialPosterior perineal block with ropivacaine 0.75% for pain control during and after hemorrhoidectomy.
As perioperative pain management is a difficult challenge during hemorrhoidectomy, we tested the hypothesis that posterior perineal block (PPB) with local anesthetics alone is able to provide adequate pain control during and after surgery. ⋯ The present study shows that PPB with 40 mL 0.75% ropivacaine (300 mg) was a simple, effective, and safe method to provide better postoperative analgesia than PCA alone following surgical hemorrhoidectomy. In addition, PPB was shown to significantly reduce opioid consumption intraoperatively and during the first postoperative day.

Randomized Controlled Trial Comparative Study Clinical TrialEfficacy of 1% ropivacaine at sacral segments in lumbar epidural anesthesia.
It is suggested that the potency of 1% ropivacaine is comparable to that of 0.75% bupivacaine and higher than that of 2% lidocaine. Alkalinized lidocaine reportedly enhances the block of sacral segments during lumbar epidural anesthesia. We hypothesized that 1% ropivacaine might also block at the lumbosacral segments adequately during lumbar epidural anesthesia. ⋯ We conclude that 1% ropivacaine does not improve block of sacral segments within 20 minutes following epidural ropivacaine administration.
