The present article lays emphasis on the various methods of sterilization and disinfection presently available. A variety of sterilants and disinfectants are being used in health care facilities across the world. Merits and demerits of various currently used sterilization and disinfection techniques have been discussed
WHY TERMINAL STERILIZATION Terminal sterilization is the preferred method for drug products because, in this process, sterilization takes place after the product has been filled into the primary arenteral products must under-go some form of sterilization, and terminal sterilization is generally the preferred method. Because sterile products man UV sterilization appears to be the optimal sterilization method from the viewpoint of eliminating surface contamination. Figure 17.2 . (A) Values of surface free energy (mJ/m 2 ) and (B) initial osteoblast adhesion of 5 V NTs, 20 V NTs, and polished Ti after sterilized by autoclaving, UV irradiation, and ethanol immersion This method has one of the lowest cycle times, resulting in the ability to sterilize equipment in high volume batches. In order to be effective, all three methods require precise control of pressure at each step within the sterilization process
Of all the methods available for sterilization, moist heat in the form of saturated steam under pressure is the most widely used and the most dependable. Steam sterilization is nontoxic, inexpensive 826, rapidly microbicidal, sporicidal, and rapidly heats and penetrates fabrics (Table 6) 827 On the basis of type of heat used, heat methods are categorized into-. (i) Wet Heat/Steam Sterilization- In most labs, this is a widely used method which is done in autoclaves.. Autoclaves use steam heated to 121-134 °C under pressure. This is a very effective method that kills/deactivates all microbes, bacterial spores and viruses -----Chemistry project-----Aim: To Determine the dosage of bleaching powder required for sterilization or disinfection of different samples o.. sterilization methods depending on the purpose of the sterilization and the material that will be sterilized. The choice of the sterilization method alters depending on materials and devices for giving no harm. These sterilization methods are mainly: dry heat sterilization
Hence, sterilization is the method of choice for the reprocessing of these items (heat stable). The FDA has approved ethylene oxide (EtO), plasma sterilization, and liquid sterilization with glutaraldehyde or PAA in heat-sensitive items. 22 , 23 All packed sterile items should be kept with proper precaution to avoid environmental contamination . The main function of packaging is to allow the sterilization of the contents, maintain the sterility until the package is opened and provide for aseptic presentation at the point of use. Packaging allows for labels, suc Reference to terminal sterilization: PDA Technical Report No. 1 (Revised 2007) Validation of Moist Heat Sterilization Processes: Cycle Design, Development, Qualification and Ongoing Control Thermal sterilization is the most commonly used sterilization method in the pharmaceutical and biotechnology industries. Industrial radiation sterilization processes utilize electron beams, gamma rays, or X-rays. Chemical sterilization is typically used for system that cannot be sterilized by other methods or for which other sterilization.

Worldwide, EO is the primary way to sterilize medical supplies. Current safety practices for the use of EO have been rigo.. Terminal sterilization is a more traditional method of sterilizing products. Put simply, terminal sterilization goes like this: fill a container, seal it and then sterilize it. That means that a product's packaging, once sealed, must be able to sustain the sterilization methods required for that product. Aseptic processing is a simple idea Thermal vs. Non-Thermal Sterilization . Non-thermal processing is considered an effective method that does not cause any deterioration of quality, in contrast with thermal processing. For example, thermally processed milk may have a cooked flavor accompanied by a loss of vitamins, essential nutrients, and flavors.; During non-thermal processing, the temperature of the food is held below the. Of the three methods, biologic monitoring is regarded as the most valid for monitoring the sterilization process, for it uses live, highly resistant bacterial spores. Chemical monitoring uses heat-sensitive or heat-time-steam-sensitive chemicals that change color and may help to immediately detect certain sterilizer malfunctions and help to.
The Real Issues with Immediate-Use Sterilization . If all the steps are not performed properly, immediate-use sterilization may increase the risk of infection. Therefore, immediate use-sterilization should be kept to a minimum and only used when there is insufficient time to process by the preferred terminal sterilization method A novel sterilization method introduced in the past several years uses high-power electrical energy to produce intense pulses of light that are claimed to provide unique bactericidal effects. 17 Called the PureBright system (PurePulse Technologies, San Diego), the technology rectifies and converts normal building ac to high-voltage dc and uses.
