bronchial washingA cytology specimen obtained after instilling 3–5 mL of isotonic saline through a bronchoscope. The resulting fluid (usually 1–2 mL), which contains cells, microorganisms or other material from the upper airways (trachea, bronchi, bronchioles), is aspirated into a trap; the material is then centrifuged to concentrate the cells, stained, and examined by light microscopy, or cultured if infection is suspected.
bronchial washingA procedure in which isotonic saline is instilled through a bronchoscope and fluid containing cells, microorganisms, or other material from the upper airways–trachea, bronchi, bronchioles is aspirated into a trap; the material is then centrifuged to concentrate the cells, stained, and examined by microscopy, or cultured if infection is suspected. Cf Bronchial brushings.
Irrigation of one or both bronchi to collect cells for cytologic study or to help cleanse the bronchi.
