A novel ultrasound-guided lateral quadratus lumborum block in dogs: A comparative cadaveric study of two approaches
Objective To describe an ultrasound-guided lateral quadratus lumborum (LQL) block
technique and the spread characteristics of lidocaine–dye injected in the LQL plane using a
transversal (LQL-T) or a longitudinal (LQL-L) approach. Study design Experimental
anatomic study. Animals A total of eight canine cadavers. Methods Bilateral ultrasound-
guided injections in the fascial plane lateral to the quadratus lumborum muscle and medial
to the thoracolumbar fascia (LQL plane) with the needle directed at the first lumbar (L1) …
