BACKGROUND
The need to monitor manual cleaning of high-risk endoscopes is recommended or more so required by the current endoscope reprocessing guidelines. The objective of this study was to establish the optimal extraction volume for colonoscopes and bronchoscopes and demonstrate the extraction efficacy for the ChannelCheck™ rapid test.
METHODS
The test soil utilized as a positive control was ATS2015 containing 20% defibrinated bovine blood. The extraction from the instrument channel of a colonoscope and bronchoscope was evaluated to establish the optimal extraction volume and the extraction efficacy for protein, carbohydrate and haemoglobin.
RESULTS
Of the extraction volumes tested, 10 mL was optimal for both colonoscopes and bronchoscopes. The extraction efficacy was 91% for carbohydrate, 83.7% for haemoglobin and 82.4% for protein.
CONCLUSIONS
The limit of detection for these analytes by the ChannelCheck rapid test meet or exceed the established levels that correlate with adequate manual cleaning of flexible endoscopes.
背景
目前的内镜处理指南建议或更需要监测高风险内镜的手动清洗。本研究的目的是确定结肠镜和支气管镜的最佳提取量，并证明 ChannelCheck™快速检测的提取效果。
方法
用作阳性对照的测试土壤是含有 20%去纤维牛血的 ATS2015。评估从结肠镜和支气管镜仪器通道的提取，以确定最佳提取量以及蛋白质、碳水化合物和血红蛋白的提取效果。
结果
在所测试的提取体积中，10 毫升对结肠镜和支气管镜均为最佳。碳水化合物的提取效果为 91%，血红蛋白为 83.7%，蛋白质为 82.4%。
结论
ChannelCheck 快速检测这些分析物的检测限符合或超过与软式内镜充分手动清洗相关的既定水平。
