Tramadol Hydrochnoride as Adjuvant to Local Anesthetic in Ultrasound Guided Erector Spinea Plane Block in Management of Chronic Chest Wall Cancer Pain

Chest wall pain is a severe and distressing symptom. The erector spinae plane block (ESPB) is an interfascial plane block where local anesthetic is injected between the erector spine muscle and the transverse process. It is a simple procedure, with easy sonographic landmarks, for postoperative analgesia in patients undergoing thoracic, abdominal, lumbar, and urologic surgery. The ESPB was initially described to relieve chronic pain from metastatic disease and rib fractures.
