“…The anaesthetic complications are related to the organs involved in the disease, but especially appertain to upper airway obstruction problems due to mucopolysaccharide infiltration of the lips, tongue, epiglottis, tonsils and adenoids (Baines and Keneally, 1983;Herrick and Rhine, 1988;Zlotogora et al, 1991). Obstructive and restrictive ventilatory defects result from abnormal laryngeal and tracheal cartilage, copious airway secretions and skeletal deformities involving the vertebrae and the thorax (Woolley et al, 1967;Young and Harper, 1982;Baines and Keneally, 1983). We describe a patient having physical and neurological features consistent with a severe clinical presentation of Hunter's syndrome (MPS II): he died following inability to manage his airway during induction of general anaesthesia for a simple procedure despite pre-induction planning.…”
