Anaesthesia for a patient with central alveolar hypoventilation syndrome (Ondine's Curse).

The perioperative anaesthetic management of an adult patient with central alveolar hypoventilation syndrome (CAHS), Ondine's Curse, is described for anterior resection of a carcinoma of the bowel. This rare syndrome results in alveolar hypoventilation, hypercarbia, hypoxaemia with secondary polycythaemia, pulmonary artery hypertension, and cor pulmonale. Epidural morphine was used for postoperative analgesia in an attempt to improve postoperative respiratory function. However, postoperative mechanical ventilation was required until recovery of the respiratory drive, which was ablated by anaesthetic drugs, epidural morphine and high inspired oxygen concentrations. The pathophysiology and treatment of this syndrome are reviewed.
