In this experimental study we compared the previous descontamination efficacy of the medical surgical materials by the use of chemical disinfectants and the mechanical cleaning with water and soap, as well as verified the organic material interference in these procedures. To carry out this study, we used surgical pincers under contamination with: Staphylococcus aureus ATCC-6538, Salmonella cholerae suis ATCC-10708, and Pseudomonas aeruginosa ATCC-15442 in presence and absence of organic matter (fetal bovine serum). The following treatments: glutaraldehyde 2%, sodium hypochlorite 1%, hydrogen peroxide 6%, alcohol 70% and the mechanical cleaning with water and soap were compared with eight repetitions in a total of 480 observations. In the described conditions, the disinfectants had a good efficacy in the previous descontamination of the medical surgical materials and a less inactivation by the organic material. The mechanical cleaning with water and soap showed a reduction of the microrganism to safe levels, considered adequate for previous descontamination.
在本实验研究中，我们比较了使用化学消毒剂和用水及肥皂进行机械清洁对医用手术材料的去污效果，并验证了有机物质对这些程序的干扰。为开展这项研究，我们使用了被以下物质污染的手术钳：金黄色葡萄球菌ATCC - 6538、猪霍乱沙门氏菌ATCC - 10708和铜绿假单胞菌ATCC - 15442，有无机物（胎牛血清）存在的情况。将以下处理方法进行比较：2%戊二醛、1%次氯酸钠、6%过氧化氢、70%酒精以及用水和肥皂进行机械清洁，每种处理重复8次，共480次观察。在所述条件下，消毒剂对医用手术材料的预去污效果良好，且受有机物质的灭活作用较小。用水和肥皂进行机械清洁可将微生物数量降至安全水平，认为足以进行预去污。
