护理SCI晨读：护理实践中玻璃微粒污染的威胁：一项初步研究
这项研究证实，在打开过程中，安瓿瓶的内容物被玻璃微粒污染，并且随品牌和含量的变化而变化。针头过滤器的使用最多可有效去除其85％。
护理实践中玻璃微粒污染的威胁：一项初步研究
摘要
目标
这项研究的目的是确定护理实践中破裂安瓿中和通过过滤去除的玻璃微粒污染的水平。
设计
按照说明将医用玻璃安瓿瓶拆开，并通过显微镜评估污染程度。
方法
使用了三种类型的内侧安瓿（A，B，C）。内含物的分配使用21或22 G针头，带或不带针筒式过滤器进行。通过光学显微镜确定颗粒。研究在2018年4月至2020年1月之间进行。
结果
94％的样品中检出的玻璃颗粒为0.94–90.70 µm。A，B和C组分别有48、162和201个玻璃颗粒。过滤对A组无效，但在其他组中有效达85％。
结论
这项研究证实，在打开过程中，安瓿瓶的内容物被玻璃微粒污染，并且随品牌和含量的变化而变化。针头过滤器的使用最多可有效去除其85％。
影响
使用注射器过滤器可以将玻璃微粒污染降低多达85％。需要进行创新的护理研究以最大程度地减少或完全避免微粒污染。
英文摘要
Aim
The aim of this study was to determine the level of glass particle contamination from medical ampoules during breakage in nursing practice and their removal by filtration.
Design
Glass medical ampoules were broken‐open as instructed and contamination was assessed microscopically.
Methods
Three types of medial ampoules (A, B, C) were used. Dispensation of contents was carried out using 21 or 22 G needles, with and without syringe‐filters. Particles were determined by light microscopy. This study was conducted between April 2018 and January 2020.
Results
Glass particles of 0.94–90.70 µm were detected in 94% of all samples. There were 48, 162 and 201 glass particles in groups, A, B and C, respectively. Filtration had no effect in group A but was effective up to 85% in the other groups.
Conclusion
This study confirms that ampoule contents are contaminated with glass particles during the opening procedure, which varies with make and content. Syringe‐filter use can be up to 85% effective in their removal.
Impact
Use of syringe‐filter can decrease glass particle contamination up to 85%. Innovative nursing studies are needed to minimize or completely avoid particule contamination.
