ObjectiveTo investigate the postoperative analgesic efficacy of ultrasound-guided lumbar erector spinae plane (ESP) blocks in patients undergoing posterior lumbar spinal surgery for lumbar spinal fractures.MethodsA total of 80 patients who were scheduled for posterior internal fixation for lumbar spinal fractures were divided into a patient-controlled analgesia (PCA) group or a combined ESP-PCA group. Numeric rating scale at rest and during movement, postoperative sufentanil consumption, and accumulative and effective bolus presses of PCA were recorded at 6, 12, 24, and 48 hours postoperatively. Numeric rating scale at rest and during movement was the primary outcome. Incidence of postoperative nausea and vomiting during the first 24-48 hours, pruritus and chronic postoperative pain, and dose of pethidine for rescue analgesia were also recorded.ResultsNumeric rating scale at rest and during movement at 6, 12, and 24 hours was lower in the ESP-PCA group (P < 0.001, P < 0.001, P = 0.0016 at rest; all P < 0.001 during movement). Lumbar ESP blocks diminished accumulative bolus presses and effective bolus presses of PCA at 6, 12, 24, and 48 hours postoperatively. Besides, patients in the ESP-PCA group had fewer demands for sufentanil and pethidine. The incidence of postoperative nausea and vomiting in the ESP-PCA group was lower than that in PCA group.ConclusionsPCA combined with lumbar ESP blocks provided superior postoperative analgesia for patients with lumbar spinal fractures treated with posterior internal fixation. Lumbar ESP blocks decreased postoperative opioid consumption and incidence of postoperative nausea and vomiting, thereby enhancing postoperative recovery.Copyright © 2020 Elsevier Inc.
