Severe bronchospasm at the termination of the cardiopulmonary bypass period is an unusual but dangerous complication of open-heart surgery. We report a case of severe unilateral bronchospasm detected at the end of the bypass period on the basis of high airway pressures with remarkable difficulties to deflate the right lung and it was relieved with bronchodilator therapy by intrapulmonary percussive ventilation. Fiberoptic bronchoscopic examination revealed unobstructed, free tracheobnncheal airway and capnographic finding was obstructive pattern. As in the previously published cases, the exact cause of bronchospasm remains unknown in our patient as well, but the possible causes of the bronchospasm are described.
Key Words: Complications; bronchospasm; Lung; bronchospasm; Surgery; open heart surgery; Ventilation; gas trapping; failure
