摘要

在加工过程的任何阶段出现污染和微生物都会使加工方法变得不安全,导致交叉传播和交叉感染的高风险。本研究的目的是评估神经外科手术中使用的吸引器械的清洁质量。实验研究在巴西一家慈善医院的材料和消毒中心以及微生物实验室进行。研究方案包括分析 10 个不同尺寸的 Yasargil 吸痰器样本。对样本进行了蛋白质测试,以检测是否存在有机物和微生物分析。数据分析采用了描述性统计方法。结果表明,40% 的仪器在人工清洁后蛋白质检测呈阳性。此外,在自动清洗后,样本中的微生物量有所增加,其中大肠埃希氏菌占 20%,产气克雷伯氏菌占 10%。这项研究提供了医疗产品清洗过程中出现故障的证据,并强调了管道中生物膜的存在,从而影响了饮用水的质量标准。

Impact of water quality on reprocessing equipment: Assessment of neurosurgical instruments cleaning and biofilm formation in hospital pipes
The presence of contamination and microorganisms at any stage of processing renders a method unsafe, leading to a high risk of cross-transmission and cross-infection. The objective of this study was to assess the cleaning quality of aspirator instruments used in neurosurgical procedures. The experimental study was conducted at the materials and sterilization center, as well as the microbiology laboratory, of a philanthropic hospital in Brazil. A study protocol was implemented, which involved the analysis of 10 samples of Yasargil aspirators with varying dimensions. The samples were subjected to protein tests to detect the presence of organic matter and microbiological analysis. Descriptive statistics were used to analyze the data. The results indicated that 40% of the instruments tested positive for protein after manual cleaning. Furthermore, after automated cleaning, samples showed an increased microbiological load, with Escherichia coli accounting for 20% and Klebsiella aerogenes for 10% of the identified microorganisms. This study provides evidence of failures in the cleaning process of healthcare products and highlights the presence of biofilm in the pipes, thereby compromising the drinking water quality standard.
