© 2022 Elsevier Inc.Quadratus lumborum block (QLB) is a new fascial plane block that may be helpful for laparoscopic surgeries. In this present study, we aim to evaluate the analgesic efficacy of QLB in laparoscopic living related donor nephrectomy (LLRDN) applied continuously via a catheter that was placed under laparoscopic vision by the surgeon. Following the approval of the Clinical Research Ethics Committee of Istanbul University, Istanbul Medical Faculty (2019/1552), 9 study (Group QLB) and 26 control (Group M) patients that underwent LLRDN were enrolled in this retrospective study. All donors underwent left nephrectomy via transperitoneal laparoscopic approach. An epidural catheter was placed between the QL and psoas major (PM) fascial plane intraoperatively by the surgeon under laparoscopic direct vision, and bupivacaine 0.25% 20 mL was injected through the catheter. After the operation, for group QLB, we used a continuous infusion of bupivacaine 0.1% 7 mL/h over 24 hours. Group M patients received intravenous morphine patient controlled analgesia for 24 hours, postoperatively. Pain scores, total morphine consumption, and complications during the first 24 hours after surgery were recorded. During the first postoperative 24 hours, morphine requirement decreased by more than 70% in Group QLB (Group QLB: 5.11 ± 1.16 mg vs Group M: 16.8 ± 7.1 mg) (P < .0001). Postoperative Numeric Rating Scale (NRS) values at the 45th minute and first hour were both significantly lower in Group QLB than Group M (P < .01). This preliminary report showed that QL catheter placement technique provides good postoperative analgesia in patients undergoing LLRDN. However, further randomized controlled studies with extended patient numbers are required to test the efficacy of the technic.
