Manejo anestésico para correção de torção vólvulo gástrica em cão - relato de caso

Abstract

Gastric dilatation-volvulus syndrome is a condition primarily affecting large, deepchested dogs. Tympanic abdominal distension accompanied by nonproductive vomiting are common clinical signs reported during anamnesis, with diagnosis confirmed via abdominal radiography. Treatment involves stabilizing the patient and performing surgical correction, which also presents challenges for the anesthesiologist, as gastric dilatation-volvulus syndrome leads to significant hemodynamic changes, including arrhythmias and hypotension, along with electrolyte imbalances, coagulopathies, and, in more severe cases, shock. This study reports a case of gastric volvulus in a dog, focusing on anesthetic management and intensive care. A 14-year-old mixed-breed dog weighing 35 kg was treated at the UFMG Veterinary Hospital. Initially, the main concern involved locomotor system changes; however, during the first follow-up, the patient developed dyspnea and was admitted to the Intensive Care Unit. Once the patient’s respiratory condition stabilized, an abdominal X-ray confirmed the diagnosis of gastric dilatationvolvulus syndrome, and the patient was referred for surgical correction. An anesthetic protocol tailored to the patient's needs was developed, utilizing drugs with minimal hemodynamic impact. Intensive care was provided before and after surgery to stabilize and continuously monitor the patient. Despite all interventions, the patient died six hours after the surgical procedure.
