Daily rubbing of iodophor is not conducive to wound healing. As a disinfectant, iodophor has a broad-spectrum bactericidal effect, which can effectively kill common bacteria, fungi, parasites and so on. However, iodophor does not have the role of promoting wound healing, but only in the early trauma wound just generated, not scabbed when the local application, can play a role in preventing wound infection. Long-term use of iodine volts on wounds will cause irritation to the wound wound surface, affecting tissue regeneration, but not conducive to wound healing. And long-term use of iodophor may cause iodine poisoning, and a few patients may also be allergic to iodine and other substances, which will further stimulate the wound can not be healed. For wounds that have already crusted over, there is no need to apply iodophor because the new soft tissues are fragile and iodophor may cause irritation to the skin tissues, making them unable to recover faster. Wound healing relies on the growth of the patient’s own soft tissues and is usually faster when the patient is in good health, has a strong self-healing ability, and can be given a comfortable growth environment. If the patient frequently strains, does not pay attention to cleaning and dressing change, and does not pay attention to protecting the wounded surface, the wound will recover more slowly. Doctors will give drugs according to the area and severity of the wound, such as common anti-inflammatory drugs, topical recombinant human epidermal growth factor, chitosan and other drugs, which can effectively help the rapid healing of the wound. At the same time, patients can appropriately supplement vitamin B2, vitamin C and trace element zinc, which can promote wound healing to a certain extent.
