Use of a modified stomach tube for bronchoalveolar lavage in dogs.J Am Vet Med Assoc. 1999 Dec 01; 215(11):1635-9, 1620.JA
A technique that did not require use of a bronchoscope for bronchoalveolar lavage (BAL) in dogs was developed. An inexpensive, readily available 16-F Levin-type stomach tube was modified for the procedure. The technique was effective for collecting BAL fluid in 9 dogs that ranged from 9.3 to 26.2 kg (20.5 to 57.6 lb). Recovered fluid was consistent with fluid collected bronchoscopically. Mean recovery volume was 84/125 ml (67%), mean WBC counts were high (> 300 cells/microl), and > 70% of cells were macrophages. Complications from use of the technique were not detected on the basis of pulse oximetry, thoracic radiography, and clinical observation. This effective, simple, and safe technique for BAL can be readily performed in clinical settings that do not have bronchoscopic capabilities. It also provides a less costly alternative than bronchoscopic BAL.
