医疗垃圾桶可以在医院传播微生物. 保持垃圾箱不到三分之二的满量,并谨慎使用盖子,可以减少患者环境污染和交叉污染风险.
科学领域:
- 控制与医疗保健相关的感染
- 医疗设施中的环境卫生.
背景情况:
- 医疗垃圾桶被认为是医院环境中微生物污染的潜在来源.
- 目前关于医疗垃圾桶管理的指导方针不足,对患者环境构成风险.
研究的目的:
- 评估医疗垃圾桶对患者护理区域微生物污染的影响.
- 评估垃圾填充水位和盖子使用对环境微生物传播的影响.
主要方法:
- 一项实验研究模拟了在患者模型上使用光乳液的微生物污染.
- 变量包括垃圾桶填充水平 (空与三分之二满) 和盖子状态 (打开与关闭).
- 通过测量患者环境中光面积的百分比来量化污染水平.
主要成果:
- 与开放,空的垃圾箱相比,开放的,被占用的垃圾箱在其侧面出现了明显更高的污染 (P=.001).
- 垃圾桶侧面的污染也在开放的,被占用的垃圾桶中高于盖子被占用的垃圾桶 (P=.003).
- 床边设备手推车的顶部在盖子占用的垃圾箱中比开放式占用的垃圾箱中污染程度更高 (P=.013).
结论:
- 医疗垃圾桶的容量不应超过三分之二,以尽量减少污染.
- 建议小心使用手动操作的盖子,以防止微生物传播和设备的交叉污染.

Standard Precaution
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...
Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
