Case 1
• 63 year old female with wheezing and had difficulty breathing. No history of smoking. She underwent a transbronchial fine needle aspirate of a central lung 4.0 cm. mass.

Bronchial aspirate
Bronchial aspirates are collected by direct aspiration of material from the large airways of the respiratory tract by means of a flexible bronchoscope.

bronchial brush biopsy listen (BRON-kee-ul brush BY-op-see)
A procedure in which cells are taken from the inside of the airways that lead to the lungs. A bronchoscope (a thin, tube-like instrument with a light and a lens for viewing) is inserted through the nose or mouth into the lungs. A small brush is then used to remove cells from the airways. These cells are then looked at under a microscope. A bronchial brush biopsy is used to find cancer and changes in cells that may lead to cancer. It is also used to help diagnose other lung conditions. Also called bronchial brushing.

INTRODUCCIÓN

La técnica de broncoaspirado es de realización frecuente en todas las unidades de cuidados intensivos. En muchos casos, de forma protocolizada se realizan, junto con la serie completa de cultivos microbiológicos, para la detección precoz de infecciones en los pacientes de UCI.



OBJETIVOS

El objetivo específico es la obtención, mediante técnica estéril de una muestra de secreciones precedentes del árbol bronquial, para su análisis microbiológico.

Tissue and Cytologic Diagnosis of Lung Cancer
The diagnosis of lung cancer can be made on tissue specimens such as endobronchial and transbronchial biopsies or resected specimens, or by assessment of cytological specimens such as transbronchial or transthoracic fine-needle aspirates, bronchial brushing and washings, bronchoalveolar lavage or sputum or pleural fluid.

Bronchial brushing is a procedure in which cells are taken from the inside of the airway mucosa or bronchial lesions through catheter-based brushing under direct visualization or fluoroscopic guidance. Flexible brushes are passed through the bronchoscope, and the bronchial surface is gently abraded to obtain the specimen. Various types of bronchial brush may be used to collect both cellular and microbiological material, using direct vision when collecting from proximal areas of suspicion or fluroroscopic screening when sampling more peripheral sites. A bronchial brushing is used to find cancer and changes in cells that may lead to cancer. It can also be used to obtain specimens for microbiologic diagnosis.

As far as I can make out, bronchial brushing is used for microbiological purposes.

I have a low confidence level because I'm not 100% sure of the proper English translation.
