Introduction
Under normal circumstances, the frequency of disinfection with iodophor should be determined based on the specific condition of the wound and the concentration of iodophor. It is generally recommended to use it 1 to 3 times daily. When treating a wound, first rinse it with clean water and gently pat dry before applying iodophor for disinfection. Additionally, change the dressing regularly and avoid exposing the wound to water to maintain cleanliness and dryness.
Generally, the frequency of disinfection with povidone-iodine should be determined according to the specific condition of the wound and the concentration of povidone-iodine. It is usually recommended to use it 1 to 3 times daily. Detailed explanation is as follows:
Povidone-iodine is a commonly used disinfectant widely applied for disinfection of skin, mucous membranes, and wounds. Its application frequency is not fixed but should be determined based on the type, size, degree of infection of the wound, and the concentration of povidone-iodine. For clean, non-infected wounds, disinfecting once daily with povidone-iodine is sufficient to maintain wound cleanliness and dryness.
However, for contaminated or infected wounds, such as wounds showing symptoms like redness, swelling, or exudate, the frequency of povidone-iodine use can be appropriately increased to 2 to 3 times daily to fully utilize its broad-spectrum antimicrobial properties, effectively combat external pathogens, and prevent further wound infection.
When treating wounds, first rinse with clean water and gently pat dry before applying povidone-iodine for disinfection. At the same time, regularly change the dressing and avoid getting the wound wet to maintain cleanliness and dryness.
