Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present.

Common methods of sterilization include physical methods and chemical methods. Physical methods include dry heat, steam, radiation, and plasmas. Radiation encompasses a variety of types, including gamma radiation, electron beam, X-ray, ultraviolet, microwave, and white (broad spectrum) light.

The methods are: 1. Moist Heat Sterilization 2. Dry Heat Sterilization 3. Gas Sterilization and Others.
Steam is one of the most popular sterilization methods. In most cases, the item that requires sterilization is placed in an autoclave or similar chamber. The combination of water vapor, high temperatures, pressure, and time destroy the microorganisms.
The sterilization methods series can help you make an informed decision. It includes 12 blog posts and covers 9 different sterilization methods that can be divided into two major categories: heat and non-heat sterilization methods.
| Methods of Sterilization | Example |
|---|---|
| High temperature | Steam, dry heat |
| Low temperature | Ethylene oxide gas, hydrogen peroxide, ozone, gas plasma, gaseous chlorine dioxide, ionizing radiation, pulsed light |
| Liquid chemicals | Chemical sterilants |
| Others | Filtration |
Sterilization is the process that kills all forms of bacteria, disease, fungi, and viruses. Disinfection procedures before and after a medical event prevent the transmission of germs. Not only will it protect the patients, but also the medical professional.
Sterilization can be achieved by a combination of heat, chemicals, irradiation, high pressure and filtration like steam under pressure, dry heat, ultraviolet radiation, gas vapor sterilants, chlorine dioxide gas etc.
The most suitable type of autoclaves for sterilizing blood bag systems are autoclaves in which sterilizing medium is a mixture of steam and air. This method, one of the counterpressure types of sterilization, is also called ‘air-over-steam’.
Advantages: more than 99% effective at preventing pregnancy. blocking the fallopian tubes and removal of the tubes should be effective immediately – but use contraception until your next period. it will not affect your sex drive or interfere with sex.
Two major contributions to the art of sterilization came in the 1860’s when the French chemist and microbiologist Louis Pasteur wrote extensively on how germs cause disease and the English physician, Joseph Lister, developed a technique that used carbolic acid as a spray to disinfect instruments.

- Heat the milk to 63°C (150°F) for at least 30 minutes or 72°C (162°F) for at least 15 seconds.
- If the temperature falls lower than the one you’re using, you have to start timing again.
Sterilization of the skin implies the absence of any living bacteria. Disinfectants used on skin and tissue, called antiseptics, are unable to sterilize the skin. Even worse, a few residual bacteria will survive, even after the most vigorous disinfection process before surgical interventions (1).
Disinfecting both the skin of the patient and the hands of the healthcare providers are an important part of surgery. Skin disinfection may be accomplished with a number of solutions including providone-iodine, chlorhexidine, alcohol based solutions, and cetrimide.
Although Ethylene Oxide is the most commonly used chemical for sterilization of devices, other chemicals are also used, and novel methodologies are being developed.
