A 5-yr 6-month-old female rainbow boa ( Epicrates cenchria ) was presented with a mass-like, localized swelling on the right side. Computed tomography (CT) scan revealed a single, comminuted, closed fracture of a vertebra causing minimal vertebral canal stenosis at the point of the localized swelling. To induce local muscle relaxation and provide l...
Peripheral nerve blocks play a critical role in pain management; however, no technique has been described to specifically target the articular nerve branches of the elbow in dogs.

Simple Summary
The GIN-TONIC block is an interfascial ultrasound-guided regional anesthesia technique that desensitizes the lumbosacral plexus and provides analgesia to the pelvic limb. Different methods have been attempted previously, such as blocking specific plexuses (e.g., lumbar and sacral plexuses) and nerves (e.g., femoral and sciatic). Howe...
