The erector spinae plane block is a novel ultrasound-guided technique that has recently been described for the management of acute and chronic thoracic pain. Currently an increasingly number of indications for the ESP block have been published. Nevertheless, the anatomy, mechanism of action, doses and volume of local anesthetic needed are still unclear. The aim of this narrative review is study this new block with base on the updated medical literature.
