| pubmed-article:1875748 | pubmed:abstractText | The identification of causative microoganisms in severe pneumonias is a usually difficult problem. Protected brushing (PB) has a good specificity but a limited sensitivity. Conventional bronchoalveolar lavage (BAL-C) has an excellent sensitivity but a doubtful specificity. The investigation of a new technique such as the protected bronchoalveolar lavage (BAL-P) appears as logical, as it should combine the advantages of PB and BAL-C without their drawbacks. | lld:pubmed |
