A nine-year-old neutered male Yorkshire terrier with history of chronic cough underwent bronchoscopy and bronchoalveolar lavage; general anaesthesia was maintained with a variable rate infusion of propofol, and oxygen was insufflated via a urinary catheter in the trachea. At the end of the procedure, desaturation occurred; endotracheal intubation was performed and was immediately followed by severe bradycardia and respiratory arrest. Glycopyrrolate (5 µg/kg) was administered leading to cardiac arrest. Apnoea and asystole were quickly treated with manual positive pressure ventilation, external chest compressions and intravenous administration of 0.04 mg/kg of atropine. This case describes vagally induced bradycardia after intubation, possible predisposing factors and its treatment/prevention with antimuscarinic drugs.
