Issue Date: | 1991 | Journal: | Critical Care Medicine | Abstract: | Objective: To assess the usefulness of the telescoping plugged catheter in the diagnosis of nosocomial pneumonia. Design: Prospective study. Patients: A total of 103 ventilated patients with suspected pneumonia were prospectively studied over 20 months. Results: The quantitative cultures of the protected brush specimen detected pulmonary bacterial infection (greater than 10(3) cfu/mL) in 49 (47.5%) patients. Subsequent follow-up confirmed pneumonia in 41 patients; in only one patient was a positive protected brush specimen culture established as a false-positive result. There were 54 patients with less than 10(3) cfu/mL and the diagnosis was excluded in 36 of them. We identified eight patients with false-negative protected brush specimen cultures. The results obtained by this technique allowed us to modify treatment in 49 (47.5%) patients. Conclusions: The telescoping plugged catheter demonstrated significant bacterial infection in a relatively small proportion of patients in whom bacterial lung infection was suspected. This technique can be safely performed and is a sensitive and specific method to establish the cause of pneumonia, thus allowing specific treatment and the avoidance of inappropriate antibiotic therapy. | URI: | http://hdl.handle.net/10553/46698 | ISSN: | 0090-3493 | DOI: | 10.1097/00003246-199102000-00010 | Source: | Critical Care Medicine[ISSN 0090-3493],v. 19, p. 171-175 |
