Background The transversus abdominis plane (TAP) exists between the internal oblique and transversus abdominis muscles, and encompasses an intersected plexus of nerves. The TAP block has been the subject of multiple clinical trials to determine its analgesic efficacy. Patients and methods A total of 60 patients were randomized into one of two groups: TAP block group (group 1) or no-TAP block group (group 2). All patients underwent a standardized anesthetic technique. The TAP block group received preincisional ultrasound-guided TAP block on the side of surgery with a 20-ml volume of 0.5% of bupivacaine, and the no-TAP group received equivalent amounts of saline. A standardized postoperative analgesic regimen composed of intravenous paracetamol and a morphine patient-controlled analgesia (PCA). The amounts of intraoperative fentanyl and post-anesthesia care unit (PACU) morphine and PCA-administered morphine, pain scores, as well as number of patients experienced postoperative nausea and vomiting in the ward at 6 and 24 h were recorded. Results TAP block group patients received a significantly lower cumulative intraoperative fentanyl, significantly less boluses of morphine in postanesthesia care unit, and significantly lower cumulative 24-h postoperative morphine dosage than the no-TAP block patients. Pain visual analog scale scores were significantly lower at both 6 and 24 h postoperatively in the TAP group when compared with the no-TAP group. There were no complications related to the TAP block procedures. No signs or symptoms of local anesthetic systemic toxicity were detected. Conclusion On the basis of our current results, preincisional ultrasound-guided TAP blocks confer analgesic benefit when added to the multimodel analgesia regimen during and after kidney transplantation.
