The specific time for wound crusting varies depending on the type of wound and the patient’s own healing ability, and cannot be generalized. Wound types are mainly divided into sterile wounds and infected wounds, generally sterile wounds, daily attention to care, within 5-7 days can be crusted healing. If it is an infected wound, because it contains more pus and other secretions, the wound can be crusted only after the pus is thoroughly removed and other microorganisms are killed in the treatment process, so the crusting time can be extended, generally 2-3 weeks. In addition, according to the patient’s physical condition, the wound healing ability is also different, if the patient has a strong self-healing ability, the scabbing time can be shortened, and patients with poor physical quality, the scabbing time can be extended, the specific time varies from person to person. In daily life, once the skin is broken, disinfection and sterilization should be carried out first, and the wound should be cleaned and sanitized to avoid further infection, and anti-inflammatory drugs should be taken for anti-infection treatment if necessary to avoid delaying the disease.
