Negative pressure of the environmental air in the cleaning area of thematerials and sterilization center: a systematic review

View Article: PubMed Central - PubMed

ABSTRACT

Objective:: to analyze the scientific evidence on aerosols generated during cleaningactivities of health products in the Central Service Department (CSD) and theimpact of the negative pressure of the ambient air in the cleaning area to controlthe dispersion of aerosols to adjacent areas.

Method:: for this literature systematic review the following searches were done: searchguidelines, manuals or national and international technical standards given byexperts; search in the portal and databases PubMed, Scopus, CINAHL and Web ofScience; and a manual search of scientific articles.

Results:: the five technical documents reviewed recommend that the CSD cleaning area shouldhave a negative differential ambient air pressure, but scientific articles on theimpact of this intervention were not found. The four articles included talkedabout aerosols formed after the use of a ultrasonic cleaner (an increased in thecontamination especially during use) and pressurized water jet (formation ofsmaller aerosols 5μm). In a study, the aerosols formed from contaminated the hottap water with Legionella pneumophila were evaluated.

Conclusions:: there is evidence of aerosol formation during cleanup activities in CSD. Studieson occupational diseases of respiratory origin of workers who work in CSD shouldbe performed.
