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.
开发了一种无需使用支气管镜对犬进行支气管肺泡灌洗（BAL）的技术。对一种廉价、易于获得的16F莱文式胃管进行了改良以用于该操作。该技术对9只体重在9.3至26.2千克（20.5至57.6磅）之间的犬收集BAL液有效。回收的液体与通过支气管镜收集的液体一致。平均回收量为84/125毫升（67%），平均白细胞计数较高（>300个细胞/微升），且>70%的细胞为巨噬细胞。基于脉搏血氧饱和度、胸部X线摄影和临床观察未发现该技术使用的并发症。这种用于BAL的有效、简单且安全的技术可在没有支气管镜设备的临床环境中轻松进行。它还提供了一种比支气管镜BAL成本更低的替代方法。
