Ultrasound-guided continuous erector spinae plane block vs continuous thoracic epidural analgesia for the management of acute and chronic postthoracotomy pain: a randomized, controlled,double-blind trial.

Introduction: Postthoracotomy pain (PTP) is a severe pain complicating thoracic surgeries and its good management decreases the risk of PTP syndrome (PTPS).

Objectives: This randomized controlled study evaluated the efficacy of ultrasound-guided continuous erector spinae plane block (ESPB) with or without dexmedetomidine compared with thoracic epidural analgesia (TEA) in managing acute postoperative pain and the possible emergence of PTPS.

Methods: Ninety patients with chest malignancies planned for thoracotomy were randomly allocated into 3 equal groups.
