Abstract: Postoperative pain is a common complaint following living kidney donation or tumor resection using the laparoscopic hand-assisted technique. To evaluate potential analgesic benefit of transversus abdominis plane blocks, we conducted randomized, double-blind, placebo-controlled study in 21 patients scheduled to undergo elective living-donor nephrectomy single-sided for tumor. Patients were randomized receive either 20 mL 0.5% ropivacaine 0.9% saline bilaterally under ultrasound guidance. We found that blocks reduced overall scores at 24 hours, with trend toward decreased total morphine consumption. Nausea, vomiting, sedation, and time discharge not significantly different between two groups. Keywords: block, nephrectomy, donor, guidance
