AbstractWe studied whether extracorporeal membrane oxygenation with a veno-venous bypass would allow withdrawal of mechanical ventilation. Three mongrel dogs were anesthetized with intravenous pentobarbital. A Swan-Ganz catheter was placed via the left jugular vein into the main pulmonary artery, and an extra-long total volume catheter was placed in the right femoral artery. The animals were placed in the lateral position, and cannulas (15 Fr.) were placed in the inferior vena cava and the superior vena cava via the right jugular vein and the right femoral vein. These cannulas were connected to a pump and a membrane oxygenator. When the pump flow was almost the same as the previous cardiac output, the partial pressure of oxygen in the pulmonary artery, was high enough to allow ventilation to be suspended. All dogs survived. This suggests that extracorporeal membrane oxygenation with a veno-venous bypass can allow mechanical ventilation to be suspended during tracheocarinal operations such as tracheocarcinal resection.
