Disease description:

A few days ago, my son fell and scraped his knee. Today it became infected with pus, so we went to the hospital where the doctor cleaned it with hydrogen peroxide solution. Could you please explain what this medication does?

Doctor's answer (1)
Dr. Li Feng
The primary clinical use of hydrogen peroxide solution is in cleaning open wounds. It effectively eliminates anaerobic bacteria from the wound site. When applied, hydrogen peroxide solution produces abundant bubbles upon contact with the wound, helping to remove foreign materials such as sand and debris from the body. Additionally, if a patient's wound has become purulent, the solution can help break down pus and dissolve abscesses.
