Ultrasound‐guided saphenous and sciatic nerve block with ropivacaine in an adult goat undergoing trochlear sulcoplasty for lateral patellar luxation

Abstract

AbstractA 75 kg, 4‐year‐old, male, neutered, Saanen‐cross, pet‐owned, adult goat presented for left trochlear sulcoplasty for treatment of lateral patellar luxation. Premedication consisted of intravenous butorphanol (0.2 mg/kg), and midazolam (0.5 mg/kg, intravenous), followed by ketamine (2 mg/kg, intravenous) and propofol (2 mg/kg, intravenous) for induction of anaesthesia. Anaesthesia was maintained using isoflurane in oxygen (100%) and mechanical ventilation was started. An ultrasound‐guided saphenous and sciatic nerve block with 0.1 mL/kg of ropivacaine 0.75% and 0.25%, respectively, was performed. Anaesthesia was uneventful, except for a transient period of hypotension and a nociceptive reaction during skin suture. Recovery was uneventful. No motor block was observed using this combination of ropivacaine concentrations. Buprenorphine (0.01 mg/kg, intravenous) was initiated (twice daily first day; once daily second and third day) 6.5 hours after the nerve block due to discomfort. Meloxicam (0.5 mg/kg, intravenous) was administered once daily for 5 days, after which the patient was fully ambulatory.
