SUMMARY:

Locorregional anesthesia is a common technique to promote analgesia and muscle relaxation in invasive procedures and other painful conditions. These techniques provide patients with effective nociceptive blockade, contributing to the stability of anesthetic plane with minimal alterations in homeostasis. The erector spinae plane (ESP) block recently described promotes visceral and somatic analgesia, being effectively used in a variety of spinal, thoracic and abdominal surgical procedures. The objective of this study is to simulate an ESP block in canine cadavers and determine whether dye would spread anteriorly to the paravertebral space, as well as the intercostal space, epidural space, and sympathetic ganglion, therefor further elucidating its clinical applications. A total of 10 canine cadavers were used in this prospective experimental study. Ultrasound guided ESP block were performed bilaterally at the T5 and L2 vertebral level using 0.5 mL.Kg-1 of a radiocontrast solution. The treatments were randomly assigned to the left or right side of each animal. Magnetic resonance imaging (MRI) of the spread was executed to determine patterns of distribution within the fascia, dorsal and ventral rami, epidural space, intercostal space and sympathetic ganglion. Potential complications (intrapleural and retroperitoneal spread) were recorded. Ultrasound guided ESP block resulted in extensive cranial-to-caudal spread within the fascia between the erector spinae muscles and the vertebrae transverse processes. Unlike previous studies, this showed consistent spread towards the ventral rami in the paravertebral, epidural, intercostal spaces, which is in accordance with previous clinical studies demonstrating the efficacy of the ESP block in thoracic and abdominal surgeries.
