RT Journal Article SR Electronic T1 Retrieval of microbiological specimens through the fiberoptic bronchoscope JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 495 OP 502 VO 52 IS 4 A1 Glenn Meden A1 Gerri S. Hall A1 Muzaffar Ahmad YR 1985 UL http://www.ccjm.org/content/52/4/495.abstract AB Lower respiratory tract infections in the immunocompromised host and hospitalized patient are a leading cause of morbidity and mortality. The methods of determining the causative agent range from sputum Gram staining to open lung biopsy. Because of the inadequacy of the former and the invasiveness of the latter, the fiberoptic bronchoscope is being used more frequently as a diagnostic tool. This paper reviews its utility in diagnosing infectious pneumonias and concentrates on the use of the microbiology specimen brush and bronchoalveolar lavage.
