Using vaporized hydrogen peroxide for anhydrous disinfection of gastrointestinal endoscopes.

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
backgroundCurrent disinfection methods for gastrointestinal endoscopes consume a significant amount of water resources and produce a large volume of waste.
aimTo achieve the objectives of efficiency, speed, and cost-effectiveness, this study utilized vaporized hydrogen peroxide (VHP) generated from sodium percarbonate granules to conduct an anhydrous disinfection test on gastrointestinal endoscopes.
methodsThe experimental device rapidly converts sodium percarbonate granules into VHP, and performs disinfection experiments on gastrointestinal endoscope models, disposable endoscopes, and various types of reusable gastrointestinal endoscopes. Variables such as the intraluminal flow rate (FR), relative humidity (RH), exposure dosage, and organic burden are used to explore the factors influencing the disinfection of long and narrow lumens with VHP.
resultsThe device generates a certain concentration of VHP that can achieve high-level disinfection of endoscope models within 30 minutes. RH, exposure dosage, and organic burden significantly affect the disinfection efficacy of VHP, whereas the intraluminal FR does not significantly impact disinfection efficacy. All ten artificially contaminated disposable endoscopes achieved satisfactory disinfection results. Furthermore, when this device was used to treat various types of reusable endoscopes, the disinfection and sterilization effects were not significantly different from those of automatic endoscope disinfection machines (using peracetic acid disinfectant solution) (
conclusionThe methods and results of this study provide a basis for further research on the use of VHP for the disinfection of gastrointestinal endoscopes, as well as for the development of anhydrous disinfection technology for gastrointestinal endoscopes.
