Project Description

The Erector Spinae Plane (ESP) Block is a novel approach to pain management for surgical procedures and acute or chronic pain.  Often a viable alternative to the epidural, this ultrasound-guided technique can be adapted to provide unilateral or bilateral analgesia to a limited region and can be performed with minimal or no sedation. By providing a thorough anatomical context from multiple views, this illustration series aims to communicate the proper, safe technique for ESP block administration to a larger audience of anesthesiologists to treat a broader patient population. A bright blue color was used to contrast the medication with the surrounding muscle.  As the illustrations show, the medication enters a plane directly above the transverse process, lifting the erector spinae muscles away from the bone.  The -¾ view of the thoracic region is used to give the operator a three-dimensional understanding in context with the spinal nerves. Sagittal and transverse sections were drawn to show that the depth of the transverse processes varies with the vertebral layer. The insets demonstrate that the L3 level is deeper than the T5 level.  On the left of the main image, shadows and transparency are used to show the relative depth of muscle groups.
