Study Notes
Sterilization and Disinfection
- The primary objective of sterilization is to completely eliminate all microorganisms from an object or surface.
- A sterile object is distinguished from a non-sterile one by the complete absence of all microorganisms, including bacterial spores.
Aseptic Measures
- In aseptic measures, the method used to fight pathogens in or on living tissue is antimicrobial chemotherapy.
Disinfection
- The main purpose of the disinfection procedure is to reduce the number of microorganisms on an object or surface to a level that is considered safe.
Gaseous Chemicals
- Gashouse chemicals like formaldehyde and ethylene oxide are used to sterilize heat-sensitive pharmaceuticals.
Filtration Sterilization
- The method used to sterilize heat-sensitive pharmaceuticals is filtration sterilization using ultrafine filters.
- One advantage of ultrafine filters in filtration sterilization is that they can remove very small particles and microorganisms from liquids.
Radiation Sterilization
- Ionizing radiation, which consists of electromagnetic waves produced by nuclear disintegration, is used to sterilize certain objects.
Disinfectants
- Isopropyl alcohol is quite effective against bacteria and fungi, but less so against viruses.
- Iodine is a halogen suitable for use as a disinfectant, showing a generalized microbicidal effect, including killing spores.
- Hydrogen peroxide is used as a mild antiseptic to disinfect mucosa, skin, or wounds, based on its chemical activity involving the splitting off of oxygen.
- One advantage of surfactants as disinfectants is their ability to reduce surface tension, making it easier to clean surfaces.
