The barrier properties of personal protective equipment are vital to healthcare personnel to protect themselves from possible infectious body fluids. Intraoperative exposure of healthcare personnel to body fluids can be substantial in both inpatient and outpatient settings. The glove-gown interface is known as one of the weakest points of the whole personal protective equipment system. However, there is a lack of scientific research designed to investigate the problem. This paper reports the results of experiments using a new testing methodology developed to quantify fluid leakage through the glove-gown interface while simulating surgical settings in terms of operating room personnel activities, exposure types, exposure durations, and physical stresses applied on the interface. This study represents one of the first efforts investigating the amount of fluid leakage through the glove-gown interface for a number of surgical gown and glove models while considering glove material differences and single double gloving. The test results showed that there is a significant difference in fluid leakage amounts between three gown models and four glove models studied. The results also demonstrated that double gloving significantly reduced the fluid leakage compared to single glove use. The mean fluid leakage was lower in the double synthetic glove configurations (M = 2.76g) compared with all other configurations (3GLV, M = 8.3g; 4GLV, M = 9.49g; 5GLV, M = 3.08g; 6GLV, M = 20.03g; double latex, M = 5.22g). Findings highlighted a significant interaction between glove and gown designs, which suggests that gown and gloves should be designed together as a system to minimize or eliminate the fluid leakage.
个人防护装备的阻隔性能对于医护人员保护自己免受可能的传染性体液侵害至关重要。医护人员在住院和门诊环境中都可能大量接触到体液。手套-手术衣界面被认为是整个个人防护装备系统中最薄弱的环节之一。然而,目前缺乏针对这一问题的科学研究。本文报告了使用新的测试方法进行的实验结果,该方法旨在模拟手术室人员活动、暴露类型、暴露时间和施加在界面上的物理压力等手术环境,从而量化通过手套-手术衣界面的液体泄漏。这项研究代表了首次针对多种手术衣和手套模型,考虑手套材料差异和单双层手套,调查通过手套-手术衣界面的液体泄漏量的努力之一。测试结果表明,在所研究的三种手术衣模型和四种手套模型之间,液体泄漏量存在显著差异。结果还表明,与单独使用手套相比,双层手套显著减少了液体泄漏。在双层合成手套配置(M=2.76g)中,平均液体泄漏量低于所有其他配置(3GLV,M=8.3g;4GLV,M=9.49g;5GLV,M=3.08g;6GLV,M=20.03g;双层乳胶,M=5.22g)。研究结果突出了手套和手术衣设计之间的显著相互作用,这表明手术衣和手套应作为一个系统一起设计,以最小化或消除液体泄漏。
