 Factors affecting Sterilization and its Efficacy

 

Based on risk adjusted classification of hospital instrument for the probability of transmitting infections Spaulding classification  we do sterilization for the critical items (that touches sterile body cavity e.g. surgical instruments) which is the a process that destroys or eliminates all forms of microbial life and is carried out in health-care facilities by physical or chemical methods to prevent disease transmission associated with the use of that item . Many methods are used for sterilizing instruments inside any health care facility e.g. Steam under high pressure, dry heat, and low temp sterilization EtO gas,  gas plasma, and liquid chemicals (which are called chemical sterilants that can be used as high level disinfectant if used for shorter exposure time) all of them have the ability to kill all pathogen if the proper procedure was implemented for reprocessing the reused items , so the sterilization is the ability to kill all living pathogen including bacterial spores which differ from disinfection that lack the ability to kill the microbial spores and are used for disinfecting non critical items and semi critical items based on Spaulding classification (the semi critical items that touches the mucus membranes can be disinfected or sterilized based on the use and the manufacturer recommendation mainly by using chemical sterilants )
