Abstract
No beneficial effects were achieved by ventilating the lungs of a group of 10 patients during total extracorporeal circulation for coronary artery bypass operation. Ventilation of nonperfused lungs, which was suggested to prevent postoperative atelectasis, may even have negative effects. Intrapulmonary shunting increased significantly (p less than 0.05), while the shunt fraction in the nonventilated lungs of another group of 10 patients remained unchanged. There were only minor differences between the two groups with respect to systemic and pulmonary hemodynamic changes.
