Bronchoalveolar Lavage in the Evaluation of Pulmonary Disease in the Dog and Cat: State of the Art

Abstract

Bronchoalveolar lavage is a diagnostic procedure used to obtain specimens representative of disease processes involving the deep lung. Saline is instilled into an airway in sufficient volumes to bathe the alveoli dependent on that airway. The saline is retrieved by suction along with cellular and acellular material lining the epithelial surfaces of the lung. Cytologic and microbiologic evaluation of the fluid can be used to characterize pulmonary diseases in the dog and cat. © 1990 American College of Veterinary Internal Medicine
