“…It has been shown to provide analgesia of both the abdominal wall and viscera in humans 6,7 which constitutes it as an alternative to neuraxial techniques and as a superior technique to the transverse abdominis plane block, which provides mainly somatic analgesia of the abdominal wall 8,9 . Multiple cadaveric studies have shown the applicability of the QLB in dogs, 4,6–9 cats 10 and goats 11 . Additionally, one clinical study has proven the analgesic effectiveness of this block in dogs undergoing ovariohysterectomy, 12 and one case report showed its analgesic potential in a cat undergoing cystotomy 13 .…”

A 2-year-old Göttingen miniature pig was presented for elective ovariectomy. After premedication with ketamine 15 mg/kg and azaperone 2 mg/kg intramuscularly, general anaesthesia was induced with propofol 1.5 mg/kg intravenously. With the animal in sternal recumbency, a 15 × 15 cm area on the dorsolateral aspect of the flank at the level of the second lumbar vertebra (L2) was clipped and aseptically prepared. Using a linear transducer, the epaxial musculature as well as the quadratus lumborum and abdominal wall muscles were identified. Then, 0.6 ml/kg of 0.25% ropivacaine was injected bilaterally at the level of L2 using a ventral-to-dorsal in-plane approach under ultrasound guidance. Anaesthesia was stable and uneventful. Predefined thresholds for nociception were not exceeded at any time. After recovery, regular pain evaluation using the Universidade Estadual Paulista (UNESP)-Botucatu pig composite acute pain scale did not indicate the need for rescue analgesia up to 4 h after the block was performed.

“…A quadratus lumborum (QL) block is an ultrasound-guided regional anesthesia technique that targets the fascial plane of the QL muscle and could provide a sensorial blockade of multiple areas of the abdomen [ 1 ]. In recent years, some anatomical and spread studies have been published with the aim of evaluating its feasibility in dogs [ 2 , 3 , 4 , 5 ], cats [ 6 ] and goats [ 7 ]. Veterinary literature also includes a case report of a cat [ 8 ].…”

The quadratus lumborum (QL) block targets the fascial plane surrounding the QL muscle providing abdominal somatic and visceral analgesia. The extension of its analgesic effects is a subject of research, as it could not cover areas of the cranial abdomen in dogs. This study assesses in eight thawed canine cadavers, the distribution of high-volume injections (0.6 mL kg−1 of a mixture of methylene blue and iopromide) injected between the psoas minor muscle and the vertebral body of L1. Anatomical features of the area of interest were studied in two cadavers. In another six dogs, QL blocks were performed bilaterally under ultrasound-guidance. The distribution of contrast was evaluated by computed tomography (CT). Hypaxial abdominal muscles were dissected to visualize the dye spread (spinal nerves and sympathetic trunk) in 5 cadavers. The remaining cadaver was refrozen and cross-sectioned. CT studies showed a maximum distribution of contrast from T10 to L7. The methylene blue stained T13 (10%), L1 (100%), L2 (100%), L3 (100%), L4 (60%) and the sympathetic trunk T10 (10%), T11 (20%), T12 (30%), T13 (70%), L1 (80%), L2 (80%), L3 (60%) and L4 (30%). These findings may suggest that despite the high volume of injectate administered, this modified QL block could not produce somatic analgesia of the cranial abdomen, although it could provide visceral analgesia in dogs.
