Idiopathic congenital central alveolar hypoventilation syndrome, otherwise known as Ondine's curse, is a rare neuropathologic syndrome characterized by an inadequate respiratory drive with hypoventilation and periods of prolonged apnea resulting in hypercarbia and hypoxemia. Although no definite pathologic abnormality has been identified to account for the disorder, it is thought to represent a primary defect related to altered function of central chemoreceptors resulting in defective control of minute ventilation. Associated problems related to neural crest cell migration, including neuroblastoma formation and Hirschsprung's disease, suggest that the primary defect is defective neural crest cell migration and function. Problems that may impact on perioperative care include the defective central control of ventilation and defective control of upper respiratory musculature, which may lead to upper airway obstruction. Although many patients will have previously undergone tracheostomy and chronic mechanical ventilation, problems in other organ systems can impact on perioperative care. Cardiovascular issues include the possible presence of cor pulmonale and autonomic nervous system dysfunction. Central nervous system issues include the frequent occurrence of seizures and mental retardation. The preoperative work-up, premedication, and the intraoperative/postoperative care and monitoring of these patients is reviewed.

The antihypoxic activity of the endogenous cyclic dipeptide cycloprolylglycine (CPG) has been studied on a model of normobaric hypoxia with hypercapnia and its neuroprotective activity has been studied on a model of human neuroblastoma SH-SY5Y cell damage by 6-hydroxydopamine. It is established that CPG exhibits the antihypoxic activity at doses of 0.5 and 1.0 mg/kg (i.p.) on outbred and BALB/c mice, but not on C57B1/6 mice. The neuroprotective activity of CPG was detected in 10(-5) - 10(-8) M concentration range only when the treatment was carried out 24h before toxin introduction. The obtained data confirm the hypothesis that piracetam is a mimetic of the endogenous CPG neuropeptide.
