Protocolo anestésico com uso da medicação Zenalpha para ovariectomia em cadela – Relato de caso

Abstract

The Mandatory Supervised Internship (MSI), a required component of the undergraduate Veterinary Medicine program at the Federal Rural University of Pernambuco (UFRPE), consists of a total workload of 420 hours and is considered an essential activity for the professional qualification of students in their final semester. During the MSI, students have the opportunity to apply the knowledge acquired throughout their studies, preparing them for practical professional activities. This report aims to describe the MSI carried out between April 1st and June 14th, 2024, divided between the Ospedale Veterinario Universitario Didattico at the University of Naples and the Ospedale Veterinario Universitario Didattico at the University of Padua, both located in Italy. The report highlights a clinical case of ovariectomy in a domestic dog (Canis lupus familiaris), utilizing Zenalpha medication, composed by medetomidine hydrochloride (0,5 mg, an alpha-2 agonist) and vatinoxan hydrochloride (10 mg, an alpha-2 antagonist), combined with inhalational anesthesia using isoflurane and analgesia with methadone, complemented by subcutaneous infiltration of bupivacaine at the surgical incision site after the procedure. It is concluded that the combination of multimodal analgesia using Zenalpha and methadone, along with inhalational anesthesia with isoflurane and infiltrative bupivacaine, represents an effective strategy to provide analgesia during and after ovariectomy in female dogs, ensuring greater comfort during the perioperative period.
