Iodophor can be applied directly to wounds. Iodophor is mainly used for disinfection and sterilization of skin breaks, and its application is relatively widespread and less irritating, painless when disinfecting wounds, disinfection effect is relatively good and non-toxic, and can be applied not only to wounds, but also to disinfect the skin before surgery and various syringes. There are some special locations that require attention. Wounds around the eyes need to be used with caution to prevent the alcohol in iodophor from causing damage to the cornea and even changing the internal structure of the eye. The oral mucosa is fragile and direct disinfection with iodophor can cause varying degrees of damage to the mucosa. Iodophor is commonly used to disinfect before surgery, but care should be taken to use it carefully for the thoracic and abdominal cavities to avoid damage caused by the use of iodophor due to the fragility of the organ mucosa. Wounds in most cases, especially those with inactive bleeding, can be disinfected with iodophor.
