Residual total protein and total organic carbon levels on reprocessed gastrointestinal (GI) biopsy forceps

摘要: Many single-use (disposable) devices are reprocessed between patient uses. In the past, a visual determination was considered endpoint of “clean” for cleaned reusable devices. this report, we measured quantitative endpoints by measuring residual total protein and organic carbon before after cleaning with commercially available cleaners medical on 15 gastrointestinal biopsy forceps inoculated three-protein test soil cleaning. Each device extracted separately tested using Bradford's reagent direct digestion method carbon. Data pre- post-cleaned were generated all five cycles. The highest amounts found precleaned 61.8 μg/cm2 39.1 μg/cm2, respectively, outer surfaces. postcleaned extracts 4.0 2.2 All visually clean. Our results provide levels forceps. © 2008 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2009
