The white color after spraying iodophor on a skin trauma may be due to oxidation, infection, and soft tissue ischemia. 1. Oxidation: When iodophor is sprayed on the wound, it may lead to the oxidation of vitamin C to form an ionic state, thus appearing white. 2. Infection: After spraying iodophor, due to local bacterial infection, it may cause purulent secretion and iodophor to react, thus causing the wound to turn white. 3. Soft tissue ischemia: If the wound is more serious, it will lead to excessive bleeding of the local soft tissue and ischemia, which will lead to local color whitening. The white color after spraying iodophor on the skin trauma may also be other reasons, please go to the regular hospital in time to consult a doctor, and actively diagnosis and treatment. In the wound recovery period should avoid local water, keep the wound clean and dry, conducive to recovery.
