Quadroiliac Plane Block for Analgesia After Renal Transplantation
Sponsor: Kanuni Sultan Suleyman Training and Research Hospital
Summary
Renal transplantation is a major abdominal surgical procedure that may cause moderate to severe postoperative pain. Opioids are commonly used as part of multimodal analgesia; however, opioid-related adverse effects such as sedation, respiratory depression, nausea, vomiting, and constipation may delay recovery and mobilization. The quadroiliac plane block is an ultrasound-guided interfascial plane block performed near the attachment of the quadratus lumborum muscle to the iliac crest. The technique may provide analgesia over a broad lower abdominal area and may reduce postoperative opioid requirements. This prospective, randomized, double-blind, controlled clinical trial will compare an ultrasound-guided unilateral quadroiliac plane block with surgical wound infiltration in adult patients undergoing renal transplantation. Participants will be randomly assigned to receive either a quadroiliac plane block with 40 mL of 0.25% bupivacaine or surgical wound infiltration with 10 mL of 0.25% bupivacaine. All participants will receive standardized multimodal analgesia and intravenous patient-controlled analgesia with tramadol. The primary objective is to compare cumulative tramadol consumption during the first 24 hours after surgery. Postoperative pain scores, dermatomal sensory distribution, motor block, nausea, vomiting, sedation, and quality of recovery will also be evaluated.

Interventions
Ultrasound-Guided Quadroiliac Plane Block
With the participant in the lateral decubitus position, a low-frequency curvilinear ultrasound transducer will be positioned immediately above the posterior superior iliac spine and oriented parallel to the vertebral column. The quadratus lumborum muscle, its attachment to the iliac crest, and the erector spinae muscle will be identified. A 22-gauge, 80-mm echogenic needle will be advanced using an in-plane approach into the fascial plane between the quadratus lumborum and erector spinae muscles. After confirmation of the target plane by hydrodissection and negative aspiration, 40 mL of 0.25% bupivacaine will be administered on the surgical side.
Surgical Wound Infiltration With Bupivacaine
Following completion of surgical closure, a total of 10 mL of 0.25% bupivacaine will be infiltrated evenly into the subcutaneous tissues along the surgical incision. The infiltration will be performed using a standardized technique before the participant emerges from general anesthesia.
