Background: Pneumothorax is the presence of free air in the pleural cavity. Air in the thoracic cavity causes respiratorydiscomfort, severe hypoxemia, decreased venous return, and haemodynamic instability, and it may lead to death. Pneumothorax can be triggered by wounds from firearm projectiles, bladed weapons, or sharp or piercing objects, as well asbites and barotrauma. The diagnosis of open pneumothorax is based on anamnesis, in combination with clinical signsobserved on physical examination. The objective of this report is to discuss the relevance of clinical-surgical managementto adequately treat evisceration of the pulmonary lobe caused by a bite in the thoracic region of a female dog.Case: This report discusses a 15-year-old female canine weighing approximately six kg with a history of wounds in thethoracic region and respiratory difficulty after being bitten by another dog. On clinical examination, she presented with abruised wound in the right thoracic region and another in the scapular region. The examination revealed evisceration of theright cranial lung lobe, which exhibited atelectasis. The animal was immediately referred to the Surgical Center. Anaesthesia was induced using propofol 2.0 mg/kg combined with ketamine hydrochloride 2.0 mg/kg, followed by intubation andmaintenance under inhalation anaesthesia with isoflurane and 100% oxygen and fentanyl 2.5 mcg/kg every 15 min. Thetemperature, non-invasive blood pressure, cardiac and respiratory frequency, pulse oximetry, capnography and electrocardiogram were monitored. Tricotomy and antisepsis of the wound were performed with 0.9% NaCl and 2% chlorhexidine.The eviscerated pulmonary lobe was immersed in saline solution, and positive pressure insufflation was performed in theinhalation circuit to verify the presence of perforation of the eviscerated lung, which was not observed. The lobe was repositioned in the correct anatomical location in the thoracic region...(AU)
