title: [The effect of volume status of the right-left shunt in a patient with a patent foramen ovale].
abstract: This is a description of the anaesthetic management of a patient with a flow patent foramen ovale undergoing intramedullary nailing of the femur. In order to detect the flow patent foramen ovale, we used transoesophageal echocardiography. During the ventilation maneuver with positive airway pressure of 20 cmH2O, a right-to-left interatrial shunt was observed. After the administration of 500 ml hydroxy-starch solution (6%) intravenously, detection of the right-to-left shunt flow was no longer possible. This case report shows that the volume status in a patient with a patent foramen ovale could influence the right to left interatrial shunt during general anaesthesia.
