Why does the wound get worse when washing it with hydrogen peroxide?

Under normal circumstances, hydrogen peroxide refers to a solution of hydrogen peroxide. The phenomenon of wounds worsening with hydrogen peroxide solution irrigation may be related to improper use, wound infection, allergic reaction, wound ischemia, deep wound injury, and other reasons. If discomfort occurs, prompt medical attention is recommended. Detailed analysis is as follows:

1. Improper Use

Hydrogen peroxide solution has strong oxidizing properties. If the concentration is too high, irrigation time is too long, or it is used incorrectly, excessive oxidation of the skin may occur, leading to worsening of the wound. Discontinue use of hydrogen peroxide solution immediately and rinse the wound thoroughly with large amounts of water to dilute residual hydrogen peroxide.

2. Wound Infection

When cleaning a wound with hydrogen peroxide solution, if the wound is already infected, the inflammatory response may be exacerbated, resulting in a more severe wound condition, i.e., worsening of the wound with irrigation.

3. Allergic Reaction

Some individuals may experience allergic reactions to components in hydrogen peroxide solution, causing symptoms such as redness, swelling, itching, and blisters at the contact site. If the allergic reaction is severe, it may significantly worsen wound ulceration.

4. Wound Ischemia

Cleaning chronic wounds or wounds with poor circulation using hydrogen peroxide solution may delay healing due to insufficient oxygen supply, leading to deterioration of the wound condition.

5. Deep Wound Injury

For deep wounds, hydrogen peroxide solution may not effectively clean the base of the wound and may instead damage healthy surface tissue, resulting in worsening of the wound with irrigation.

When using hydrogen peroxide solution to clean wounds, attention should be paid to controlling the amount and concentration to avoid excessive cleaning that may damage wound tissue. Additionally, keeping the wound dry to prevent infection is important.
