Erector Spinae Plane Block

A novel inter-fascial plane block first described in 2016. This technique has been used for analgesia for the following procedures:

- Video-assisted thoracoscopic surgery (VATS)

- Pulmonary lobectomy

- Thoracic rib and sternal fractures

- Mastectomy

- Axillary sentinel lymph node biopsy

- Abdominal surgery

- Hip surgery

- Thoracic neuropathic pain relief


Unique Contraindications:

- Localized active infectious process at injection site

- Extensive tissue depth between skin and transverse process limiting visualization of transverse process


Unique Complications:

- Pneumothorax

- Lower extremity motor weakness if performed at lower thoracic level



- Transverse probe at midline of the spine and identify spinous process, lamina, transverse process and rib

- Slide probe laterally and center view over transverse process

- Rotate probe 90 degrees to parasagittal view of transverse process

- Insert needle from cranial to caudal direction and contact transverse process

- Inject local anesthetic aiming for pooling above transverse process and lifting of erector spinae muscle.  For this video, 30 ml of Ropivacaine 0.5% was used.



- Other postural positions (i.e. prone or lateral) may facilitate placement

- Although the T5 transverse process had been the traditional plane of insertion, the block can be performed at any level

- Rostral spread 2-3 levels and approximately 5 levels caudally

- Ultrasound identification/differentiation of the target transverse process and its transition to its adjacent rib can ensure injection at the correct site

- Transverse process appears as blunt and flat while the rib is seen as round on ultrasound with pleura clearly seen in close proximity

- Constant visualization of the needle along its entire length until its contact to the transverse process may decrease the likelihood of a pneumothorax

- Consider use of weight-appropriate dose of local anesthetic to decrease the likelihood of LAST
