Nerve Block Gallery - Erector Spinae Anatomy Scan
Caption
Dynamic view of the anatomy of the erector spinae block. This view is obtained using the linear transducer in a sagittal orientation. The clip starts in the midline, and a pinpoint hyperechoic thoracic spinous process is briefly seen. As the probe is swept laterally, broad hyperechoic transverse processes are seen, with the erector spinae muscles just superficial to these. Further laterally, the transverse processes disappear and broad hyperechoic ribs come into view, with sliding pleura visible underneath. Notice the lack of visible pleura when transverse processes are in view. The erector spinae block is performed in the plane viewing transverse processes, without ribs/pleura visible. Drs.
