Microscopic observations on tracheal aspirates from ventilated neonates. II. The onset of bronchopulmonary dysplasia and other changes.
A total of 450 undiluted and unprocessed tracheal aspirates from 120 intubated infants were examined microscopically for evidence of bronchopulmonary dysplasia and other changes. In 19 infants desquamated sheets of dysplastic epithelium in the fresh aspirate provided an early indication of developing bronchopulmonary dysplasia. Examination of unstained tracheal aspirates can provide, within minutes, information not only about the onset and development of bronchopulmonary dysplasia, but also provide evidence for milk or formula aspiration and for gastro-oesophageal reflux.
