Abstract: Fondo La coenurosis cerebral es una enfermedad del sistema nervioso central en ovejas y cabras, y suele ser mortal a menos que se proporcione alivio quirúrgico. La información sobre la neuroanestesia en medicina veterinaria en cabras es escasa. Presentación del caso Describimos el manejo anestésico de una cabra hembra intacta (2 años; 16 kg) presentada para una craneotomía. La cabra se sedó con xilazina (0,05 mg kg − 1, i.m.) y morfina (0,05 mg kg − 1, i.m.). La anestesia general se indujo 20 min más tarde con propofol y se mantuvo con una infusión a velocidad constante de propofol (0,2 mg kg − 1 min − 1). Se colocó un tubo endotraqueal con manguito y se conectó a un sistema de recirculación (círculo) y se inició la ventilación mecánica con oxígeno al 100%. Se administró un bolo de lidocaína (1 mg kg − 1), midazolam (0,25 mg kg − 1) y fentanilo 2,5 μg kg − 1 por vía intravenosa seguida inmediatamente de una infusión a velocidad constante de lidocaína (50 μg kg − 1 min− 1), midazolam (0,15 mg kg − 1 h − 1) y fentanilo (6 μg kg − 1 h − 1) administrados por vía intravenosa a lo largo de la cirugía. Se realizó craniectomía y la cabra se recuperó sin problemas. Conclusión La anestesia intravenosa total con propofol, lidocaína, fentanilo y midazolam podría ser una opción aceptable para la anestesia durante la cirugía intracraneal en cabras.Background Cerebral coenurosis is a disease of the central nervous system in sheep and goats, and is usually fatal unless surgical relief is provided. Information regarding neuroanaesthesia in veterinary medicine in goats is scant. Case presentation We describe anaesthetic management of an intact female goat (2 years; 16 kg) presented for craniectomy. The goat was sedated with xylazine (0.05 mg kg−1, i.m.) and morphine (0.05 mg kg−1, i.m.). General anaesthesia was induced 20 min later with propofol and maintained with a constant rate infusion of propofol (0.2 mg kg−1 min−1). A cuffed endotracheal tube was placed and connected to a rebreathing (circle) system and mechanical ventilation with 100% oxygen was initiated. A bolus of lidocaine (1 mg kg−1), midazolam (0.25 mg kg−1) and fentanyl 2.5 μg kg−1 was delivered via the intravenous route followed immediately by a constant rate infusion of lidocaine (50 μg kg−1 min−1), midazolam (0.15 mg kg−1 h−1) and fentanyl (6 μg kg−1 h−1) administered via the intravenous route throughout surgery. Craniectomy was undertaken and the goat recovered uneventfully. Conclusion Total intravenous anaesthesia with propofol, lidocaine, fentanyl and midazolam could be an acceptable option for anaesthesia during intracranial surgery in goats.
