The erector spinae plane block for effective analgesia after lung lobectomy

Abstract

Abstract Rationale: The thoracic epidural block and thoracic paravertebral block are widely used techniques for multimodal analgesia after thoracic surgery. However, they have several adverse effects, and are not technically easy. Recently, the erector spinae plane block (ESPB), an injected local anesthetic deep to the erector spinae muscle, is a relatively simple and safe technique. Patient concerns: Three patients were scheduled for video assisted thoracoscopic lobectomy with mediastinal lymph node dissection. All the patients denied any past medical history to be noted. Diagnoses: They were diagnosed with primary adenocarcinoma requiring lobectomy of lung. Interventions: The continuous ESPB was performed at the level of the T5 transverse process. The patient was received the multimodal analgesia consisted of oral celecoxib 200\u200amg twice daily, intravenous patient-controlled analgesia (Fentanyl 700 mcg, ketorolac 180\u200amg, total volume 100 ml), and local anesthetic (0.375% ropivacaine 30\u200aml with epinephrine 1:200000) injection via indwelling catheter every 12\u200ahours for 5 days. Additionally, we injected a mixture of ropivacaine and contrast through the indwelling catheter for verifying effect of ESPB and performed Computed tomography 30\u200aminutes later. Outcomes: The pain score was maintained below 3 points for postoperative 5 days, and no additional rescue analgesics were administered during this period. In the computed tomography, the contrast spread laterally from T2-T12 deep to the erector spinae muscle. On coronal view, the contrast spread to the costotransverse ligament connecting the rib and the transverse process. In the 3D reconstruction, the contrast spread from T6-T10 to the costotransverse foramen. Lessons: Our contrast imaging data provides valuable information about mechanism of ESPB from a living patient, and our report shows that ESPB can be a good option as a multimodal analgesia after lung lobectomy.
