Erector Spinae Plane Block for the Treatment of Intractable Pain in a Patient with Pancoast Tumor: A Case Report

Abstract

Introduction: The erector spinae plane (ESP) block is a regional anesthetic technique that involves injecting a local anesthetic below the erector spinae muscle in an interfascial plane. Case Presentation: We report a case of a 66-year-old man with cervicothoracic junction pain caused by an advanced Pancoast tumor. The administration of ESP block at the T2-T3 level led to pain relief of more than 50% in this patient after two sessions. Conclusions: Therefore, the application of this method of regional analgesia is both convenient and safe and reduces opioid consumption. Further studies are needed to evaluate the safety and effectiveness of continuous blocks in outpatient settings.
