Ethylene oxide
Is ethylene oxide harmful to health?
What is ethylene oxide?
Ethylene oxide is a highly effective sterilising agent commonly used in the medical industry to sterilise sensitive equipment and materials such as PCR tests, smear tests, and face masks.
PCR tests and masks were used senselessly throughout the recent pandemic, has this use created more harm than good?
Ethylene oxide is classified as a carcinogen
However, ethylene oxide is classified as a carcinogen by the International Agency for Research on Cancer (IARC), raising concerns about its safety and potential health risks associated with its use.
Effectiveness:
Ethylene oxide is highly effective at sterilising medical equipment and materials without compromising their integrity or functionality. It is particularly well-suited for sterilising sensitive instruments and materials that cannot withstand the high heat of autoclaving. The use of ethylene oxide ensures that medical devices are free from harmful microorganisms, reducing the risk of infection in patients undergoing diagnostic tests or medical procedures.
Regulatory Approval:
Despite being classified as a carcinogen, ethylene oxide is approved for use as a sterilising agent by regulatory bodies such as the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA). Strict guidelines and regulations govern the use of ethylene oxide to minimise exposure and ensure the safety of healthcare workers and patients.
Lack of Alternatives:
While there are alternative sterilisation methods available, such as steam sterilisation and hydrogen peroxide gas plasma sterilisation, these methods may not be as effective or practical for certain medical devices and materials. Ethylene oxide remains a preferred choice for sterilising heat-sensitive and moisture-sensitive items, such as PCR tests, smear tests, and face masks.
Examples:
PCR tests
Ethylene oxide is commonly used to sterilise PCR tests, which are used for diagnosing infectious diseases and genetic disorders. The accuracy and reliability of PCR tests depend on the sterility of the materials used, making ethylene oxide an indispensable sterilising agent in laboratory settings.
Smear tests
Ethylene oxide is also used to sterilise smear tests, which are used to screen for cervical cancer and other gynecological conditions. The use of ethylene oxide ensures that the testing materials are free from contaminants that could affect the accuracy of the results and compromise patient safety.
Face masks
With the increased demand for face masks during the COVID-19 pandemic, ethylene oxide has been used to sterilise disposable masks for reuse. While the carcinogenic properties of ethylene oxide raise concerns, the need for sterile and effective face masks to prevent the spread of infectious diseases outweighs the potential risks associated with exposure to the sterilising agent.
Conclusion: In conclusion, ethylene oxide is a carcinogenic sterilising agent that is still used to sterilise PCR tests, smear tests, and face masks due to its effectiveness, regulatory approval, and lack of practical alternatives. While the carcinogenic properties of ethylene oxide raise concerns about its safety, the benefits of using ethylene oxide for sterilisation in medical settings outweigh the risks when proper safety precautions and regulatory guidelines are followed. Further research and developments in sterilisation technology may lead to safer alternatives in the future, but for now, ethylene oxide remains a crucial tool in maintaining the sterility of medical equipment and materials.
Ultimately it is up to each of us to research medical procedures before agreeing to anything being done to our body and always weigh up the risks.
