Airway Obstruction and Flattening of Arterial Pressure Wave during Whole Lung Lavage

Abstract

Whole lung lavage (WLL) is a challenging procedure; because lavage fluid may perturb the respiratory and hemo-dynamic systems. We observed severe airway obstruction and flattening arterial pressure wave during WLL for treat-ment 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 ob-struction and decrease cardiac outflow through the mass effect. Key Words: bronchospasm, lavage, pulmonary alveolar proteinosis
