Hydrogen peroxide solution can be used to clean wounds. Hydrogen peroxide solution is hydrogen peroxide and is commonly used in surgical practice, especially in emergency departments for wound cleaning in trauma patients. Because patients with traumatic wounds, especially those caused by cuts or other external forces, will contain a large number of bacteria in the wound and need to first clean and disinfect the wound with hydrogen peroxide solution. After cleaning, the patient must rinse the hydrogen peroxide completely with physiological saline, then disinfect it twice with iodophor, and finish with wound debridement and suturing.
