Randomized trial compares injectate distribution in feline cadavers, suggesting ultrasound-guided ESP blocks are viable for pain relief.

The study aims to compare the efficacy of longitudinal versus transverse approaches for lumbar erector spinae plane blocks in feline cadavers.
Utilized 15 feline cadavers for injections, 3 for anatomical dissection and 12 for ultrasound-guided injections (24 sides)
Injections performed at L3 with methylene blue, lidocaine, and iopromide (0.4 mL kg−1 per side)
Needle placement confirmed by ultrasonography, followed by CT and dissection for distribution evaluation.
Contrast spread was predominantly longitudinal across all injections, with transverse approach showing exclusive longitudinal distribution
Longitudinal approach showed ventral spread beneath transverse processes in 25% of sides
Significantly more L1 dorsal branch staining with the transverse approach (p = 0.033).

Carrillo-Flores et al. (2026) studied this question.
