Preparation of instruments to be sterilized
The general aspects of disinfection and sterilization in healthcare facilities have been reviewed recently in detail (5). The decontamination of medical devices is a complex task. Chemical decontamination (pre-disinfection) by soaking in a detergent and disinfectant liquid is now a well-established practice. There are two types of packaging, reusable (containers) and disposable (pouches and sheets). The composition of containers has evolved considerably (composite materials with patterns that facilitate the elimination of condensates). Trays wrapped with sterilization sheets, preferably non-woven, are now preferred because they provide very good steam diffusion.
