Abstract

A 12-year-old female labrador retriever weighing 27 kg required anaesthesia for an explorative thoracoscopy and intrathoracic mass biopsy. One lung ventilation was achieved using a bronchial blocker. After surgery, the dog was moved to the induction room with the bronchial blocker still in place. Once reconnected to an anaesthetic machine, absent capnography trace during mechanical ventilation, increased circuit pressure during manual ventilation and reduced tidal volume with subsequent haemoglobin desaturation occurred. After excluding other possible causes, bronchospasm due to direct bronchial blocker stimulation was suspected. Removal of the bronchial blocker, reintubation with a new endotracheal tube, administration of ketamine, adrenaline, isoflurane, theophylline and salbutamol led to the resolution of the clinical symptoms within four hours. No further episodes occurred. The dog was discharged in good general conditions seven days later.
