There are usually many different kinds of disinfectant solutions, and the choice of disinfectant solution varies depending on the situation. If it is an ordinary soft tissue injury wound or a wound after surgery, it is usually disinfected with 75% alcohol or iodophor. If it is a fresh wound, combine the application of hydrogen peroxide and saline to repeatedly rinse the wound 2-3 times, then disinfect with iodophor or 75% alcohol. However, if it is used for soaking of instruments, 95% alcohol is usually used for soaking, which is very effective. If it is used for washing or bladder irrigation, furacilin solution should be used for irrigation. Furacilin solution is generally rarely used for disinfection of superficial soft tissues because the disinfection effect is not too good.
