How to deal with a skin break on the leg

Nowadays, many people wear relatively thin clothes, and they wear shorts in the summer, so many people may accidentally fall and break the skin on their legs while walking or running. At this time, you should first clean off the dust on the wound and then disinfect it after cleaning, because this will help prevent the wound from getting infected, so that it will not fester and become difficult to scab after infection, and it is easy to leave scars. In severe cases, it may also cause some viruses to enter the blood.

If the skin is damaged after an injury and is contaminated with dust, dirt and other pollutants, it is necessary to rinse the pollutants with running tap water or spring water, and then use appropriate trauma medication.

Iodine tincture has no irritation to mucous membranes

Povidone-iodine is a bactericidal disinfectant. Compared with alcohol and iodine tincture, the pain caused by povidone-iodine is milder, and it is non-irritating and non-corrosive to the mucous membranes. It can be used to disinfect the skin and mucous membranes, and can also treat burns. It can also form a protective film on the wound, which is beneficial to the healing of the wound. The disinfection of skin wounds needs to be retained for more than 2 minutes.

The shelf life of iodine tincture is generally two years. For home use, it is best to choose a 100 ml small bottle and store it in a light-proof, cool place.

Iodine and alcohol irritate the skin

When it comes to skin disinfection, the classic combination of iodine and alcohol usually comes to mind. 2% iodine tincture is a commonly used skin disinfectant with strong bactericidal and astringent effects, but it has a certain irritating effect on the skin and is not suitable for mucous membrane damage. After using iodine tincture to disinfect the skin, it is necessary to promptly apply alcohol to remove the iodine.

70% to 75% alcohol can be used for skin disinfection, but alcohol is easily absorbed by the skin and has a significant irritating effect on the mucous membranes. It is not suitable for skin damage with damaged mucous membranes. In addition, it is not recommended to use alcohol to treat wounds on children's skin injuries.

Long-term use of hydrogen peroxide is detrimental to mucosal and tissue healing

Hydrogen peroxide has strong permeability and oxidizing effect. It is often used in medicine to clean wounds and for local antibacterial effects. When it comes into contact with wounds, pus or pollutants on the skin and mucous membranes, it immediately decomposes to produce oxygen. After killing the bacteria, the remaining substance is water that is non-toxic and non-irritating.

Therefore, hydrogen peroxide is an ideal disinfectant for wound disinfection. However, highly concentrated hydrogen peroxide should not be used to disinfect wounds to prevent skin burns. Long-term use is not conducive to the healing of mucous membranes and tissues, and it is not easy to preserve effectively at home.

Bactroban and erythromycin ointment are suitable for post-traumatic skin infection

Topical antibiotics are suitable for skin infections following trauma. Apply topically to the affected area to protect the wound surface. If necessary, you can bandage or cover it with a compress. It is forbidden for those who are allergic to the above drugs.

It is recommended to use less red and purple medicine

Mercurochrome is a weak disinfectant and antiseptic. Since mercurochrome is non-irritating to the skin, mucous membranes and wounds, it is often used to disinfect general minor injuries and skin and mucous membrane wounds, as well as to disinfect the skin and urinary tract before minor surgical and ENT operations. Due to its weak penetrability, it has only a small antibacterial effect. Its effect will be reduced when encountering organic matter and alkaline environment, so the disinfection effect is not reliable.

Gentian violet is a dilute solution made from the chemical gentian violet. Its bactericidal effect is between that of iodine and mercurochrome. Because it has a selective inactivation effect on Gram-positive bacteria, especially a strong killing effect on Staphylococcus aureus, Corynebacterium diphtheriae, Candida albicans, etc., it is generally used in a 0.1% to 1% aqueous solution to treat skin and mucous membrane trauma infections, and can also be used for small-area burns.
