The aim of this study was to assess a modified approach to QLB to minimise potential complications such as abdominal organ puncture. Nine canine cadavers were included and were positioned in lateral recumbency. An ultrasound-guided QLB was performed on each side. The probe was placed in the transverse position over the lumbar muscles just caudal to the last rib, and a needle was advanced in-plane from a dorso-lateral to a ventro-medial. A volume of 0.2 mL kg􀀀1 of a mixture of iomeprol and methylene blue was injected. Computed tomography (CT) and dissection were performed to evaluate the spreading. Success was defined as staining of the nerve with a length of more than 0.6 cm. Potential complications such as intra-abdominal, epidural, or intravascular spreading of the mixture were also assessed. The CT images showed a T13 to L7 vertebra distribution, with a median of 5 (3–6). Dissection showed staining of the nerves from T13 to L4, with a median of 3 (2–5). No complications were found. This modified approach to QLB is safe and shows similar results to the previous studies in canine carcass.application/pdfspopen accessAnestesia local.Anestesia veterinaria.Veterinary anesthesia.Quadratus lumborum muscle - Imaging.Cuadrado lumbar - Diagnóstico por imagen.Perros - Anestesia.Local anesthesia.Dogs - Anesthesia.Artículohttps://doi.org/10.3390/ani11102945https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es
