A 13-year-old boy with myotonic dystrophy underwent insertion of a percutan
eous gastrostomy feeding tube under general anaesthesia. We used a laryngea
l mask airway and a spontaneously breathing technique with propofol total i
ntravenous anaesthesia. Postoperative vomiting and aspiration, 12 h after t
he procedure, subsequently required intubation and ventilation. We discuss
the anaesthetic management of this case and review the features of the dise
ase to be considered when contemplating anaesthesia in such patients.
