Whether to sterilize an implant wound with povidone-iodine or alcohol depends on the location, depth and size of the wound. Povidone-iodine has a broad-spectrum bactericidal effect and is used as an antiseptic and disinfectant in medical treatment. It can be used to disinfect the skin as well as the mucous membranes, and the irritation and pain caused by povidone-iodine is relatively mild and easy to accept. Alcohol is also known as ethanol, if the wound is relatively small, you can use 75% alcohol for skin disinfection, can not be used for large wounds and mucous membrane disinfection, it will cause transient severe pain, if the wound needs to be implanted with alcohol can not be used, it will lead to necrosis of the newborn cells. And the early dressing change after implantation, because alcohol can affect the survival rate of the skin piece, also not recommended to use. Patients are advised to choose the appropriate wound antiseptic under the guidance of the doctor, and not to use it blindly so as not to aggravate the development of the disease.
