Abstract
It was aimed to evaluate the diagnostic utility of bronchoalve Veolar lavage (BAL) from cases of infiltrative diseases of lung admitted at Choithram Hospital & Research Centre, Indore (M.P.) during 2003 to 2004. The analysis included gram's staining, semi quantitative bacterial culture, AFB smear and culture, WBC and differential count and cytology. The gram's staining was found to have 83.6% sensitivity as compared to semi quantitative culture. Colony count >10,000 / ml was considered as significant and 142 specimens yielded single organism while 56 had poly-microbial infections. Gramnegative bacilli like E.coli, Klebsiella spp. and Pseudomonas aeruginosa formed pyogenic infections. The analysis revealed pyogenic infections in 51%, tuberculosis in 21%, fungal infections in 12% and malignancy in 2% cases. Thus, the analysis of BAL specimen is valuable in the diagnosis of infiltrative disorders of lung.
