Is bronchoalveolar lavage good?

summary

Bronchoalveolar lavage (BAL) is a procedure in which the lung segments or sub lung segments below the bronchus are repeatedly lavaged and recycled with sterile normal saline through fiberoptic bronchoscope. A series of tests and analyses are carried out to obtain the nature and activity of the lower respiratory tract lesions, which is helpful to establish the diagnosis. Let's share my experience with you.

Is bronchoalveolar lavage good?

Indications: etiological diagnosis of pulmonary infection, especially immunocompromised and immunodeficient pulmonary infection; Cytological diagnosis of diffuse and peripheral lung tumors; Diagnosis, treatment, efficacy and prognosis of interstitial lung diseases, such as sarcoidosis, idiopathic pulmonary fibrosis, exogenous allergic alveolitis, alveolar proteinosis, collagen vessels with pulmonary fibrosis.

Bronchofiberscope is a technique of repeatedly lavaging and recovering the lung segments or sub lung segments below the bronchus with sterile normal saline, and a series of cytological, biochemical, enzymatic and immunological tests and analysis of the recovered solution are carried out.

1. Whole lung lavage: used for the treatment of pulmonary alveolar proteinosis, silicosis, alveolar microlithiasis, persistent state of asthma, etc. 2. Lung segment lavage: it is mainly used in the diagnosis of diffuse interstitial pulmonary fibrosis, asbestosis and Pneumocystis carinii pneumonia, and also has important value in the diagnosis of diffuse alveolar carcinoma.
