Iodine can kill viruses, etc. Some people have mites and other things on their faces, which can easily cause acne on their faces. Povidone can be used. Povidone is often used on the skin and can also be used to treat many skin diseases. It is not recommended to use iodine on the face, mucous membranes, etc., because it has a corrosive effect. Incomplete deiodination can stain the skin. It has a strong effect of killing pathogens and is prone to reactions. When using iodine, pay attention to the following four points: Do not use iodine on a large area to prevent iodine poisoning caused by a large amount of iodine absorption. It is generally not used on ulcerated skin. It is forbidden to use iodine. Iodine is prohibited from being applied at the same time as red mercury (commonly known as red medicine) to avoid mercury poisoning (reaction to generate mercuric iodide). The application of physiological saline is mainly for flushing and moisturizing. For a wide and uneven wound, wiping is unrealistic. Flushing can remove pollutants from the wound surface. The concentration of iodine sold in the market is 2%.
Iodine can denature the proteins of pathogens. It is generally used on mucous membranes with rich blood supply, low chance of infection, and keen sense. (Povidone) In addition, physiological saline can enhance the nutrition of granulation tissue and absorb wound secretions, and has no adverse stimulation to granulation tissue. Physiological saline cotton balls and gauze can be used to clean wounds, wet wound compresses, fill abscess cavities, and flush abscess cavities. Hypertonic saline, 3-10% saline has a strong local dehydration effect. Hypertonic saline plus vaseline gauze can stimulate the growth of granulation tissue. It is often used in clinical practice for wounds that have not been closed in the first stage, or after the infected wound is thoroughly debrided. Hypertonic glucose, clinically, a 50% concentration of glucose injection is usually called hypertonic glucose. (Povidone) Hypertonic glucose is a dehydrating drug that can be evenly distributed on the wound surface, enhance plasma osmotic pressure and produce a dehydrating effect, causing cell dehydration, loss of reproductive ability, bacterial death, and local cell dehydration of the body, reducing wound and granulation tissue edema. At the same time, it can form a protective film to prevent cells from continuing to invade and infect, improve local blood circulation, improve nutrition around the wound surface, and promote wound healing.
In addition, glucose also has a myogenic effect, which can reduce wound pain and facilitate wound healing. It is commonly used for: patients with poor local nutrition of infected wounds, large wound areas, poor or ineffective dressing after other dressing changes; patients with varicose veins on the surface of the skin erosion and ulcers of the lower limbs, and difficult wound healing; patients with shallow II-deep II small-area edema and slow wound healing; and patients with more obvious bedsores. (Povidone) Hydrogen peroxide (hydrogen peroxide solution) 3% hydrogen peroxide decomposes and releases oxygen after contact with tissues, which has an effect. It is used to rinse traumatic wounds, corrupt or foul-smelling wounds, especially for infected wounds.
