ABSTRACT Brachycephalic obstructive airway syndrome (BOAS) presents a substantial anaesthetic and nursing challenge, with patient outcome heavily influenced by how effectively stress, airway patency and oxygen demand are managed throughout admission, anaesthesia and recovery. Careful, calm handling and proactive stress reduction are crucial, as anxiety and panting can increase oxygen requirements and precipitate airway collapse in dogs with BOAS. Thoughtful drug selection and readiness for emergency intubation or tracheostomy will help veterinary nurses respond quickly to sudden decompensation. Close monitoring of ventilation, cardiovascular status and temperature allows early intervention in the case of hypercapnia, vagal episodes or hypothermia, all of which can significantly worsen recovery in BOAS patients. The recovery period is the stage of highest risk, so maintaining the patient in sternal recumbency with the head elevated, delaying extubation until the patient is fully awake and having equipment for re-intubation immediately to hand are pivotal safety measures. Ongoing nursing vigilance for subtle changes in respiratory noise and effort or oxygen saturation allows intervention measures to be implemented early before complete airway obstruction occurs. In the longer term, clear owner education on harness use, weight control, appropriate diet, environmental modification and recognition of deteriorating breathing will support sustained improvement in patient welfare beyond hospital discharge.
