Objective

To investigate the analgesia of a continuous transversus abdominis plane (TAP) block over the first 24 postoperative hours in renal transplanted patients.

Patients and methods

This prospective randomized study included 40 adult patients scheduled for living-related kidney transplantation. They were randomized into two equal groups: group I underwent a ultrasound-guided continuous TAP block with 20 ml bupivacaine 0.5% bolus, followed by a continuous infusion of 10 ml/h of bupivacaine (0.25%) for 24 h and group II received the same block with the same volume and infusion rate as isotonic saline. Pain at rest and on sitting, sedation, and nausea and vomiting were assessed at 2, 6, 12, and 24 h postoperatively. The total intraoperative analgesic requirement, time for the first request for analgesia, and total postoperative meperidine over 24 h were assessed.

Results

Postoperative Visual Analogue Scale scores at rest were significantly lower in the Bupivacaine group between 2 and 12 h postoperatively and Visual Analogue Scale scores on movement were significantly lower in the Bupivacaine group at 2, 6, 12, and 24 h postoperatively. Postoperative sedation scores were significantly higher in the Control group at 4 and 6 h. The total meperidine requirement was significantly higher in the Control group (161±31 mg) compared with the Bupivacaine group (57±30 mg) (P<0.001). There was no significant effect of TAP on postoperative nausea.

Conclusion

TAP block appears to be a good alternative for postoperative analgesia following living-related kidney transplantation. It reduced pain scores and opioid consumption in the first 24 h.
