[Anesthetic management of a Paget's disease patient complicated with Parkinson disease]

Paget's disease is a metabolic disorder of unknown etiology characterized by excessively rapid remolding of bone. We report a case of Paget's disease complicated with Parkinson syndrome. A 69-year-old female patient was scheduled for ventriculo-peritoneostomy due to hydrocephalus. Her manifestations included disability to walk, slight deafness and muscular rigidity of limbs, without symptom of intracranial hypertension. After induction of anesthesia with thiopental and vecuronium, tracheal intubation with Macintosh laryngoscope was attempted but failed because mouth opening was restricted to only 3 cm. Again with Bullard laryngoscope, she was successfully intubated. During neurosurgical operation, the anesthesia was maintained with low concentration of isoflurane (under 0.3%), nitrous oxide and oxygen. The surgery was completed without adverse events such as disorder of autonomic nervous system. However 6-days after operation, ventilatory arrest occurred due to bronchial obstruction with sputum. Immediately, re-intubation was performed without any sequela and tracheostomy was also performed. In conclusion, as reported previously, intubation and postoperative pulmonary dysfunction should be carefully taken care of, and Bullard laryngoscope was useful for this patient.
