Hydrogen peroxide, also known as hydrogen peroxide, is a strong oxidant, which can kill all bacterial propagules, including mycobacteria, viruses, fungi and their spores, and most bacterial spores. It has broad-spectrum sterilization effect and belongs to advanced disinfection. Hydrogen peroxide disinfectant is most commonly used for indoor air disinfection and terminal disinfection of space and object surface disinfection. It can also be used for surface disinfection of general objects, disinfection of surgical wounds and skin mucosa, disinfection of corrosion-resistant medical instruments, etc. Hydrogen peroxide is a clean and green chemical disinfectant because of its active chemical properties, easy decomposition into oxygen and water, and no secondary pollution to the environment.
Ninth edition of prevention and control plan: hydrogen peroxide can be used for terminal disinfection service
Annex 8 of the ninth edition of the prevention and control plan: Guidelines for the transfer of epidemic risk personnel in COVID-19
(1) cases and asymptomatic infected persons.
Requirements for transport vehicles: it should be kept in a closed state during transshipment. After the handover, the vehicle should be disinfected at the end, ventilated with windows, and wiped and disinfected with hydrogen peroxide spray or chlorine-containing disinfectant.
(2) Close contacts
After transshipment. Carry out terminal disinfection on the vehicle, open the window for ventilation, and use hydrogen peroxide spray or chlorine-containing disinfectant to wipe and disinfect the carriage and its surface.
Annex 10 of the ninth edition of the prevention and control plan: technical guide for disinfection of epidemic foci in COVID-19.
(1) surface disinfection of environmental objects: disinfectants such as chlorine-containing disinfectants, chlorine dioxide, quaternary ammonium salt 108, peracetic acid, hydrogen peroxide, hydrogen persulfate, potassium persulfate, etc. can be wiped, sprayed or soaked for disinfection; Physical disinfection and other safe and effective harmless treatment methods can also be adopted.
(2) Indoor air disinfection: You can choose disinfectants such as peracetic acid, chlorine dioxide and hydrogen peroxide for spray disinfection, or you can choose safe and effective physical disinfection methods and harmless treatment methods such as circulating air sterilizer and ultraviolet lamp.
(3) Hand hygiene: It is recommended to rub hands with hand sanitizer for disinfection. Disinfectants such as 75% ethanol and hydrogen peroxide can also be selected.
Sterilization of hydrogen peroxide disinfectant;
Generally speaking, it is difficult to disinfect hospitals all over the world, especially operating rooms, instruments and intensive care units. Items to be disinfected include the following four categories:
Clostridium difficile: This bacterial family is characterized by its ability to produce spores under pressure. It usually has two states. Among them, it is difficult to be killed when it exists in the form of spores.
MRSA: short for methicillin-resistant Staphylococcus aureus, commonly known as superbug. The characteristic of this bacterium is that it can mutate itself. Resistant to more and more antibiotics.
Viruses: mainly include poliovirus and norwalk virus.
MREA: Enterobacter sakazakii with gas production resistance.
These microorganisms are difficult to be killed by traditional disinfection products (including chlorine-containing disinfectants, benzene, aldehydes, etc.). ) because they have many protective layers, especially spores, which have a round or oval protective layer, consisting of high-density cytoplasm and a closed envelope around the nucleus. Even ordinary hydrogen peroxide won't kill spores.
Vantone vaporized hydrogen peroxide can kill 6-log bacterial spores, including Clostridium difficile and other common bacteria in hospitals, such as MRSA, VRE, Acinetobacter baumannii and viruses. After vaporized hydrogen peroxide sterilization, surface sampling shows that it can eradicate the pathogens of common bacteria in hospitals such as Clostridium difficile.
During the epidemic period, Fantong vaporized hydrogen peroxide played a great role in terminal disinfection of medical environment. At present, it has been used for high-level disinfection of medical environment, including terminal disinfection of ICU wards, examination rooms, fever clinics, ambulances and other scenes!
