This is a randomized, placebo controlled, double blind study to determine the effectiveness of a Transversus Abdominis Plane (TAP) block for reducing postoperative pain and opioid use in kidney transplant recipients.
The management of post-operative analgesia in kidney transplant recipients is complex secondary to labile fluid shifts and limitations in the use of NSAIDs secondary to their potential nephrotoxicity. A majority of transplant centers rely on the use of intravenous patient-controlled opioid analgesia as the predominant method of post-operative pain control, however this practice is at odds with the worldwide initiatives to reduce post-operative opioid use and dependence. This study is a single center prospective randomized double blinded study which will compare the post-operative benefits of TAP block with liposomal bupivacaine plus free bupivacaine versus placebo (normal saline) TAP block in participants receiving both the ARS and the Gibson incisions for kidney transplantation . Approximately 200 participants will be enrolled at the Cleveland Clinic. The operative approach (i.e. Gibson or ARS) is at the discretion of the operating surgeon and will proceed in the standard fashion. At the completion of the dissection of the external iliac vessels and prior to bringing the transplant kidney into the field, an intraoperative TAP block will be performed by inserting a 22 gauge spinal needle from inside the abdomen into the transversus abdominus plane of the abdominal wall at the lateral superior and inferior border of the surgical dissection and injecting the pre-determined analgesic or placebo. The remainder of the procedure, including the vascular and urinary anastomosis, will proceed identically between the two groups. All participants will receive the same post-operative abdominal surgical dressing. Post-operative pain control will follow standard clinical guidelines. All participants will be prescribed on-demand oral Oxycodone 5 or 10 mg tablets plus IV Morphine or IV Dilaudid if needed for severe breakthrough pain. On discharge, all participants will receive ten 5 or 10 mg Oxycodone tablets.

Level of postoperative pain using using an adapted version of the brief pain inventory (BPI) which uses a 10-point numeric scale from 0-10.
The adapted brief pain inventory (BPI) uses a 10-point numeric scale, from 0-10. 0 indicates no pain and is the best outcome, 10 indicates the worst pain and is the worst outcome.
Time frame: Daily from the day after transplant (Post operative day 1) until day of discharge or 7 days, whichever comes first, then weekly for 3 weeks, then every 2 weeks for 2 months, then at 6 months and 12 month post surgical date
