Instrument Uses Instrument sterilizers: Used to sterilize instruments in absence of an autoclave Dressing drums: storage of gowns, cotton, linen, etc.
Disinfection uses liquid chemicals on surfaces and at room temperature to kill disease-causing microorganisms. Ultraviolet light has also been used to disinfect the rooms of patients infected with Clostridioides difficile after discharge. [14] Disinfection is less effective than sterilization because it does not kill bacterial endospores. [15]
Sterile dental instruments from hospital central supply (barcoded label indicating sterilization date, expiry date and contents). The central sterile services department (CSSD), also called sterile processing department (SPD), sterile processing, central supply department (CSD), or central supply, is an integrated place in hospitals and other health care facilities that performs sterilization ...
Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in fluid or on a specific surface or object.

Some computer-controlled autoclaves use an F 0 (F-nought) value to control the sterilization cycle. F 0 values are set for the number of minutes of sterilization equivalent to 121 °C (250 °F) at 103 kPa (14.9 psi) above atmospheric pressure for 15 minutes. Since exact temperature control is difficult, the temperature is monitored, and the ...
The practice of reusing medical devices labeled for only one use began in hospitals in the late 1970s. [8] After a thorough review by the U.S. FDA in 1999 and 2000, [8] the agency released a guidance document for reprocessed SUDs that began regulating the sale of these reprocessed devices on the market, [9] under the condition that third-party reprocessors would be treated as the manufacturer ...
"High-level disinfection kills all organisms, except high levels of bacterial spores" and is done with a chemical germicide marketed as a sterilant by the U.S. Food and Drug Administration (FDA). "Intermediate-level disinfection kills mycobacteria, most viruses, and bacteria with a chemical germicide registered as a 'tuberculocide' by the ...
Earle Spaulding of Temple University (Philadelphia, Pennsylvania) in a 1939 paper on disinfection of surgical instruments in a chemical solution proposed "a strategy for sterilization or disinfection of inanimate objects and surfaces based on the degree of risk involved in their use". [1]
