Introduction: Thoracic erector spinae plane block is now performed in many different surgical procedures, including lumbar spinal fusion. We evaluated the analgesic effect of lumbar ESP performed at L4 after lumbar spinal fusion surgery.
Methods and case series: Eight patients scheduled for lumbar spinal fusion were included in the case series. Erector spinae plane block was performed at L4 preoperatively, administering 20ml of 0.2% ropivacaine on each side. We recorded patient-reported pain intensity during the first 48 postoperative hours using a visual analogue scale (VAS) and rescue analgesia requirements. Pain at rest was controlled in all patients (VAS 0 to 3), although pain on movement ranged from mild to severe (VAS 0 to 8). Rescue analgesia consumption ranged from 1 to 22mg morphine.
Conclusions: Lumbar ESP appears to contribute to pain control during the first 48hours after lumbar spinal fusion.
