Hydrogen peroxide is a chemical compound with a list of uses ranging from bleaching to caring for fish, depending on the concentration. It's most common use, in a low concentration, is disinfecting. Skin injuries can be as simple as mild abrasions where the skin is barely broken to a laceration or puncture wound where several layers of skin are torn. To eliminate germs and bacteria to prevent infection, hydrogen peroxide is an important part of the injury treatment process.
Step 1
Rinse away blood under cool running water.
Step 2
Pour 1 tsp. 3 percent hydrogen peroxide onto the skin injury.
Step 3
Pour another 1 tsp. of 3 percent hydrogen peroxide onto the area and allow it to fizz. Repeat this process until the fizzing stops.
Step 4
Pat the area dry with a clean cloth.
Step 5
Bandage the area with sterile gauze or a sterile bandage depending on the size and location of the injury.
Tips and Warnings
- Elevate the affected area to above heart level and apply mild pressure to stop persistent bleeding. Clean the area and change the bandage daily.
- Do not use hydrogen peroxide in or around the eyes. Do not use a concentration higher than 3 percent hydrogen peroxide to treat skin injuries. For bleeding that will not stop or large deep injuries, seek emergency medical care immediately as stitches may be required. Fever, red streaks, and swelling are all indication of infection. Seek emergency medical care.
