Anatomical description of anaesthetic spread after deep erector spinae block at L-4
SJDL González, J Pomés, A Prats-Galino… - Revista Española de …, 2019 - Elsevier
Introduction Thoracic erector spinae plane (ESP) block is now used for postoperative
analgesia. However, although reports of lumbar ESP have been published, the anesthetic
spread and mechanism of action of this technique remains unclear. We describe the lumbar
ESP block technique and evaluate the spread of 20 ml of solution administered at the level
of the transverse process of L4 in a cadaver model. Methods Observational study after 12
lumbar ESP blocks at L4 on a fresh cadaver model (6 bilaterally). The spread of 20 ml of …
