1. What is Sterilization?

• Sterilization is a phrase referring to any
  process that eliminates or kills all forms of
  microbial life, including transmissible agents
  (such as fungi, bacteria, viruses, spore forms,
  etc.) present on a surface, contained in a fluid,
  in medication, or in a compound such as
  biological culture media. Sterilization can be
  achieved by applying the proper combinations of
  heat, chemicals, and irradiation, high reassure,
  and filtration.
• The term has evolved to include the disabling or
  destruction of infectious proteins such as prions
  related to Transmissible Spongiform
  Encephalopathy (TSE).

4. What is ETO Sterilization?

• ETO Stands for Ethylene Oxide Sterilization
• Ethylene oxide sterilization is a type of
  chemical process consisting of four primary
  variables namely gas concentration, humidity,
  temperature and time.
• Ethylene oxide is an alkylation agent that
  disrupts DNA of microorganisms, which prevents
  them from reproducing.
• ETO sterilization assures that a safe and sterile
  product will be delivered to the market each and
  every time.

5. Why where ETO Sterilization used?

• World / industries have been praising
  sterilization by steam superlative for
  destroying bacteria, fungi and spores.
• Steam sterilization is also most cost effective
  easy to use method available but steam is not
  applicable to all materials and instruments.
• Advancement in medical procedures has resulted in
  the increased usage of delicate instruments which
  cant be steam sterilized as they cannot survive
  excessive temperatures or moisture of steam. So
  Heat and moisture sensitive equipment require
  alternative methods of sterilization. And that is
  where ETO Sterilization is used.

6. Fact about ETO Gas?

• ETO gas is carcinogenic, explosive and mutagenic.
• Ethylene Oxide (ETO) is a common gas used for low
  temperature sterilization.
• It is a colorless, poisonous gas that attacks the
  cellular proteins and nucleic acids of
  microorganisms.
• It is most commonly used to sterilize instruments
  with long lumens such as endoscopes and all
  materials that have to be sterilized but cannot
  withstand higher temperature.
• ETO process temperatures from 25 - 55C are used.
  A lower temperature results in a less efficient
  process which leads to a longer exposure time.

Note EtO sterilization should be used only when
another method is not appropriate.

7. What is ETO Sterilizer?

• ETO Sterilizer is equipment, which facilitate ETO
  Sterilization process.
• ETO Sterilizers are available in various
  capacities from 0.45m3 to 44m3 volumetric
  capacities to carry out ETO Sterilization.

9. Sterilization cycle in ETO Sterilizer

• There are 3 phase in ETO Sterilizer
• Preconditioning
• Sterilization
• Aeration (Degassing)
• Cycle time is usually more than 14 hours.

10. Advantages of ETO Sterilization

• Low temperature
• High efficiency destroys micro-organisms
  including resistant spores
• Large sterilizing volume/ chamber capacity
• Non corrosive to plastic, metal and rubber
  materials

11. Disadvantages of ETO Sterilization

• Excessively Long cycle
• Safety concerns - carcinogenic to humans
• Toxicity issues - toxic residues on surgical
  instruments and tubing
• Not recommended for flexible scope
• ETO is flammable
• Requires special room conditions, safety
  equipment and separate ventilation system
• Relatively high annual costs for maintenance,
  servicing and consumables.
