[Postoperative pulmonary tissue changes after autogenous lung and artificial lung bypass].
The changes in autogenous lung oxygenation and artificial lung during cardiopulmonary bypass (CPB) were compared. The results of our investigation showed that autogenous lung oxygenation is less injurious to the lung than bubble oxygenation and is more physiological. We think that during autogenous lung bypass and open heart surgery, the lung is functioning physiologically and is supplied with normal amount of oxygen, while using bubble oxygenation for CPB the native lung is the only nonperfused organ and lung function being insulted by pulmonary ischemia which is one of the most important reason for pulmonary injury after CPB.
