Abstract

Objective: To verify the association between different types of ambient ventilation in Central Sterile Supply Department (CSSD), fractional exhaled nitric oxide (FeNO) values, and respiratory symptoms of workers .

Methods: CSSD workers from five hospitals were evaluated in three different ventilation systems: negative air pressure, air conditioning, and natural ventilation. The prevalence of respiratory symptoms was evaluated by The European Community Respiratory Health Survey. The respiratory inflammatory response was evaluated utilizing FeNO level measurements.

Results: There was a general prevalence of respiratory symptoms in 5% of the workers investigated; there was no association between respiratory symptoms and ventilation systems (p = 0.170). Of the total workers investigated, 22% had FeNO levels ≥ 25 parts per billion (ppb), considered above the normal range, and there was a statistically significant difference between ventilation systems (p = 0.009) favoring natural ventilation.

Conclusion: Exposure to the natural ventilation system reduced the chance of developing FeNO levels ≥ 25 by 94.3%.

暴露于不同通风系统的中央无菌供应科工作人员的分次呼出一氧化氮和呼吸道症状。

目的：验证中心无菌供应科（CSSD）不同环境通风方式与工人呼出一氧化氮分数值（FeNO）的相关性。方法：对5家医院的CSSD工人在负压、空调和自然通风三种不同的通风系统下进行评估。欧洲共同体呼吸系统健康调查评估了呼吸道症状的流行程度。使用FeNO水平测量评估呼吸道炎症反应。结果：接受调查的工人中有5%普遍存在呼吸道症状；呼吸系统症状与通气系统无相关性（p = 0.170）。在接受调查的所有工人中，22%的FeNO水平≥25十亿分之一（ppb），被认为高于正常范围，并且在有利于自然通风的通风系统之间存在统计学显著差异（p = 0.009）。结论：暴露于自然通风系统可使FeNO水平≥25的几率降低94.3%。

期刊介绍： International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
