Whole lung lavage (WLL) is a challenging procedure; because lavage fluid may perturb the respiratory and hemodynamic systems. We observed severe airway obstruction and flattening arterial pressure wave during WLL for treatment of pulmonary alveolar proteinosis. The aim of this case report is to discuss the anesthetic requirement in order to prevent bronchospasm during WLL. Furthermore, we discuss the potential of lavage fluid to cause airway obstruction and decrease cardiac outflow through the mass effect.
Severe bronchospasm during cardiac surgery is an uncommon, but serious problem. A 52-year-old woman with a mosaic attenuation pattern on the whole lung field was scheduled for repair of an atrial septal defect under minimally invasive cardiac surgery. Bronchospasm developed intraoperatively, but the underlying ventilatory impairment, poor performance of one-lung ventilation and initiation of cardiopulmonary bypass delayed diagnosing and treating the bronchospasm. The bronchospasm induced severe pulmonary edema that required postoperative ventilatory care.

The parasympathetic nervous system has been considered to have an important role in bronchospasm. Although vagal reflexes are well documented in animal models of airway hyperresponsiveness, their importance in asthmatic attacks in man is less documented. We report a case of bronchospasm during sclera buckling operation and we believe that this patient's bronchospasm was induced by the vagal reflex.
