Medical hydrogen peroxide, also known as hydrogen peroxide, is a strong oxidizing disinfectant that is suitable for disinfection of most body surfaces and contaminated wounds, such as wounds with severe dust contamination or large amounts of dirt and dust, which can be flushed with medical hydrogen peroxide. The concentration of medical hydrogen peroxide is usually less than 3%, so the pain will be mild, but patients who are sensitive to pain may experience a little irritation when wiping the wound with hydrogen peroxide. When hydrogen peroxide touches the wound, it will instantly oxidize to form more bubbles on the wound, so after rinsing with hydrogen peroxide, you can further rinse with sterilized saline and then eliminate it completely with iodine volts to achieve three times disinfection to maintain a sterile wound.
