Reduction of post-bronchoscopy pneumonia by working channel irrigation with sterile saline before diagnostic procedures.
Article in BMC pulmonary medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAfter transbronchial biopsy with flexible bronchoscopy, pneumonia sometimes occurs as a complication. The goal of our study was to determine whether irrigation of the working channel before diagnostic procedures can reduce the frequency of post-bronchoscopy pneumonia.
methodsInitially, we examined the effect of working channel irrigation with 100 mL of sterile saline to reduce the number of bacteria attached to the working channel. Subsequently, we compared the frequency of post-bronchoscopy pneumonia in patients who underwent or did not undergo working channel irrigation before bronchoscopic biopsy or lavage fluid collection.
resultsTHE MAIN
findingsA significant reduction in bacterial colonies was observed in the irrigated channel-flush samples. Of the 242 enrolled participants, 109 were in the exploratory group, whereas 133 were in the control group. The frequency of post-bronchoscopy pneumonia (PBP) was 2.8% (n = 3) and 3.8% (n = 5) in the exploratory and control groups, respectively.
conclusionsWhile the irrigation by suctioning 100 mL of sterile saline was effective in reducing the bacterial load within the channel, the reduction in pneumonia incidence did not reach statistical significance, indicating the need for further accumulation of cases.
