Ultrasound-guided sciatic nerve block, target muscular contraction to nerve stimulation in a 11-week-old female African leopard (Panthera pardus). (A) Acoustic window obtained with a linear transducer (10 MHz) positioned distal to the greater trochanter of the femur, with a transverse orientation to the long axis of the limb (L, lateral; M, medial; Cr, cranial; Cd, caudal). (B) Leopard positioned in lateral recumbency with the limb to be blocked uppermost. The needle is introduced in plane, and advanced in a cranial direction through the semitendinosus muscle, until its tip is positioned close to the perineural tissues. Nerve stimulation is used to achieve muscular response with >0.3 and <0.5 mA. CP, common peroneal nerve; T, tibial nerve.

Ropivacaine 0.5% (0.15 mg/kg) was administered after a negative aspiration test and in the absence of resistance to injection (Figure 1).
Ultrasound-guided saphenous nerve block in an 11-week-old female African leopard (Panthera pardus). (A) Acoustic window of the inguinal region obtained with a linear transducer (10 MHz), placed perpendicular to the long axis of the limb, at the level of the middle third of the thighbone. Note the femoral artery and vein, and the saphenous nerve cranial to them (L, lateral; M, medial; Cr, cranial; Cd, caudal). (B) Leopard positioned in lateral recumbency with the limb to be blocked uppermost, abducted 90 , and extended caudally. The needle is introduced in an in-plane approach and advanced in a craniocaudal direction. FA, femoral artery; FV, femoral vein; SN, saphenous nerve.
