[Central alveolar hypoventilation as a complication of massive intracerebellar hemorrhage: report of a case treated by diaphragm pacing].
The author reported a case of central alveolar hypoventilation (Ondine's curse) which was treated by diaphragm pacing. A 59-year-old man was admitted because of sudden deep coma and tetraparesis. Neurological examination on admission showed miotic pupils with absent light reaction, no oculocephalic reflex, no corneal reflex and tetraparesis. Glasgow scale was evaluated to be E-1 V-1, and M-3 with total of 5 points. Computed tomography confirmed a large hematoma in the cerebellum with ventricular rupture. Immediately, a suboccipital craniectomy was performed and the hematoma was evacuated. His neurological condition was improved gradually within a month after the operation. He responded to verbal orders and moved all his limbs against gravity. His respiration, however, was irregular with a pattern of so-called "cluster breathing" followed by prolonged apnea, that was more pronounced in night. He was suffered from hypoxic hypercapnea and recurrent pneumonia. Therefore, authors decided to employ diaphragm pacing for management of central alveolar hypoventilation. A diaphragm pacemaker (radiofrequency induction) was implanted. A cuff electrode was put around the right phrenic nerve in the right thorax, and the receiver installed subcutaneously in the right anterior chest. Postoperative respiratory study showed ventilation on pacing with satisfactory blood gas and he became able to move around using a wheel chair. In 1966 Glenn demonstrated a new technique to move the diaphragm paced by a receiver through the phrenic nerve, triggered by radio wave from external device.(ABSTRACT TRUNCATED AT 250 WORDS)
