Bi-level erector spinae plane block for the control of severe back pain related to vertebral metastasis

摘要

Pain is the most common reason for emergency department visits. Traditionally, pain management has been provided by narcotics, non-steroidal anti-inflammatory drugs and non-narcotics. Erector spinae plane block is a new interfascial plane block that has been successfully used for acute pain control in different surgeries. Two female patients with severe back pain related to breast cancer metastasis applied to emergency department. The pain scores of the patients were between 8 and 10. We performed bilateral erector spinae plane block at the levels of T3 and T6. The pain scores decreased under 2 within 30 min and none of the patients required additional analgesic agent for 24 hours. Previously erector spinae plane block was used for rib and spine fractures in emergency department. Different from previous cases, we performed bi-level blocks to cover a larger area and the block abruptly and effectively reduced pain scores of the patients with breast cancer.
