Cor pulmonale and the Pierre Robin anomaly. Airway management with a nasopharyngeal tube.

Summary An infant with Pierre Robin anomaly was anaesthetised for cardiac catheterisation. There was cor pulmonale with the pulmonary artery pressure at systemic level, a patent foramen ovale and a persistent ductus arteriosus. The effects of alterations in blood gases on the haemodynamics and intracardiac shunts are considered. Subsequent management of the obstructed airway with a nasopharyngeal tube for 4 weeks is described.
