Iodophor and iodine are both iodine-containing disinfectants, with iodophor being less concentrated and iodine being more concentrated. Iodophor is mainly used for disinfection of general wounds, and some infected wounds can also be wet dressed with iodophor. For skin and mucous membrane surgery, iodophor can also be used to disinfect. However, if iodine is applied to disinfect the skin, it must be deiodinated with alcohol and cannot be applied simply to disinfect the skin, because if iodine stays on the skin surface for a long time, it can easily lead to chemical burns, and iodine cannot disinfect mucous membranes and soft tissues.
