ESP block (erector spinae plane) is a paraspinal fascial block, the basis of which is the injection of a local anesthetic deep under the extensor muscle of the back and superficially to the ends of the transverse thorax. The injection site is located far from the pleura, large blood vessels and spinal cord.
An indication for the implementation of the blockade is a fracture of three or more ribs.
ESP block is easier to perform than thoracic epidural analgesia and thoracic paravertebral block.
The mechanism of action is the diffusion of local anesthetics to the anterior and posterior branches of the spinal nerves. Video
