二十年前即开始用硬支气管镜和顶端带有气囊的导管楔入Ⅰ级或Ⅱ级支气管采取呼吸道标本,研究呼吸道免疫和炎症状况。这种技术也曾用于肺泡蛋白沉着症的治疗。十余年来由于纤维支气管镜的应用,支气管肺泡灌洗(BAL)得到进一步发展,现已被广泛接受,成为比较方便而无多大危险性的检查方法。用本法采取肺泡表面液体标本,进行细胞成分和非细胞成分的研究,使许多肺疾病、尤其是肺间质性疾病的认识得到很大提高,并已
Twenty years ago, hard bronchoscopy and balloon catheters were wedged into grade I or grade II bronchi and airway specimens were taken to study respiratory immune and inflammatory conditions. This technique has also been used for the treatment of pulmonary alveolar proteinosis. More than ten years due to the use of fiberoptic bronchoscopy, bronchoalveolar lavage (BAL) has been further developed, has now been widely accepted as more convenient and without much risk of the test. The use of this method to take liquid samples of alveolar surface, cell components and non-cellular components of the study, many lung diseases, especially interstitial lung disease awareness has been greatly improved, and
