We investigated eyewear contamination levels in the operating room to assess infection risk and inform protocol development. Microbial contamination after use was found in 37.7% of disposable and 94.9% of reusable eyewear pieces. After disinfection, 74.4% of reusable eyewear also cultured positive. Disposable eyewear may reduce intercase contamination risk. Reusable eyewear may carry ongoing bioburden and, thus, contribute to operating room environment risk. Eyewear with antimicrobial material or components could reduce risk. Alternative decontamination methods for reusable eyewear should be evaluated.
我们调查了手术室中眼镜的污染水平，以评估感染风险并为制定相关规程提供依据。发现一次性眼镜使用后有37.7%存在微生物污染，可重复使用眼镜有94.9%存在污染。消毒后，74.4%的可重复使用眼镜培养结果仍呈阳性。一次性眼镜可能会降低病例间的污染风险。可重复使用眼镜可能会持续携带生物负荷，从而增加手术室环境风险。带有抗菌材料或部件的眼镜可以降低风险。应评估可重复使用眼镜的替代消毒方法。
