BackgroundSpinal surgery is a procedure that causes intense and severe pain in the postoperative period. Erector spinae plane (ESP) block can target the dorsal-ventral rami of thoracolumbar nerves, but its effect on lumbar surgery is unclear. The aim of this study was to investigate the effect of the ESP block on postoperative opioid consumption and pain scores in patients undergoing spinal surgery.MethodsSixty patients undergoing open lumbar decompression surgery were randomly assigned to 2 groups. The ESP Group (n = 30) received ultrasound-guided bilateral ESP block with 0.25% bupivacaine 20 mL. In the Control Group (n = 30), no intervention was performed. Postoperative analgesia was performed intravenously twice a day with 400 mg ibuprofen and patient-controlled analgesia with tramadol. Postoperative visual analogue scale scores, opioid consumption, rescue analgesia, and opioid-related side effects were evaluated.ResultsCompared with the Control Group, the visual analogue scale scores were statistically lower in the ESP Group during all measurements of time, both at rest and active movement (P < 0.05). Tramadol consumption was lower in the ESP Group compared with the Control Group at all time periods (P < 0.05). Twenty-four hour tramadol consumption in the Control Group was significantly higher compared with the ESP Group (370.33 ± 73.27 mg and 268.33 ± 71.44 mg; P < 0.001, respectively) and the difference was 28%, and time to first analgesic requirement was significantly longer in the ESP Group than in the Control Group.ConclusionsESP block can be used in multimodal analgesia practice to reduce opioid consumption and relieve acute postoperative pain in patients undergoing open lumbar decompression surgery.Copyright © 2019 Elsevier Inc.
