The preferred method of sterilization during drug production is heat. Heat sterilization can occur in two forms: moist or dry. Autoclaving is the most commonly used application of moist heat for sterilization. Which of the following statements about autoclaving is true?

a. When autoclaving solid items, they should be wrapped in foil to help maintain sterility

b. Autoclaving requires extensive exposure times in order to achieve sterilization

c. Autoclaving is preferred over dry heat because it can effectively be used to sterilize a wide variety of items, including liquids, powders, metal instruments and glassware

d. The effectiveness of an autoclave is dependent on an increase in pressure and corresponding increase in temperature.

Autoclaving is a heat treatment widely used in the hospital environment and consists of keeping contaminated material at a high temperature through contact with water vapor for a period of time sufficient to destroy all pathogens.

The process includes compression and decompression cycles to facilitate contact between vapor and contaminated materials. The usual pressure values range from 3 to 3.5 bar and the temperature reaches 135ºC. Having the advantage of being relatively simple and can be used to sterilize various types of hospital supplies. Thus, we can conclude that the effectiveness of an autoclave depends on a pressure increase and corresponding temperature increase.
