Abrasions do not necessarily require daily application of iodized povidone, depending on the extent of the abrasion. Superficial skin abrasions generally do not need to be applied every day; when the skin is broken, it needs to be applied every day; when bleeding occurs in abrasions, not only does it need to be applied every day, but it should also be bandaged and sterilized. Generally for superficial skin abrasions, iodized povidone is not needed, only need to be rinsed off with saline. If the abrasions appear broken skin, it is necessary to apply iodine povine every day to the wound for local disinfection, can effectively prevent local infection. For bleeding abrasions, not only do you need to apply iodized povidone every day, but you also need to bandage the wound and change the dressing and other methods of treatment. Usually, the use of povidone-iodine should be carried out reasonably under the guidance of a doctor. It is generally recommended that abrasions with broken skin can be sterilized with povidone-iodine 1 or 2 times a day, and for abrasions with bleeding, it is recommended to use it every 6 to 8 hours.
