The correct way to use a band-aid.

Band-aids have now become a household essential, but not everyone knows how to use them correctly. They should not be seen as a universal remedy; proper usage is necessary to avoid causing unnecessary pain to the patient.

There are several key points to pay attention to when using a Band-aid correctly:

1. Understand the indications for the wound. Band-aids are mainly used for stopping bleeding from acute minor wounds, especially suitable for clean, superficial, small cuts that do not require stitching. The length of the wound should not exceed the width of the Band-aid. For deeper wounds, those with major blood vessels, nerve, tendon damage, or suspected foreign objects, they should not be used. Conditions such as boils, burns, purulent infections, and various skin diseases are also not suitable for Band-aids.

2. The wound should be disinfected. Some people have developed purulent infections in the area after using a Band-aid, primarily because they did not check and clean the wound beforehand. Before using a Band-aid, the wound must be carefully checked for any dirt. If there are any contaminants, the wound should be cleaned thoroughly with disinfected saline, dried, and then treated with iodine glycerin before applying the Band-aid. If the wound is caused by a rusty object, a tetanus antitoxin injection (with a negative skin test) should be administered immediately to prevent tetanus. When applying, slight pressure should be applied to help stop the bleeding.

3. Pay attention to protecting the wound. When using a Band-aid, it is important to protect the wound and avoid active bleeding. The injured area should be kept still, kept dry, and protected from contamination. Avoid frequently pressing on the wound with your hands, and prevent any impact that could cause the wound to reopen.

4. Be mindful of changes in the wound. After using a Band-aid, it is important to observe any changes in the wound and to change the Band-aid regularly to prevent infection. If after 24 hours the wound becomes more painful or there is discharge, it should be opened and checked promptly. If signs of infection such as redness, swelling, or exudate are observed, usage should be stopped, and a visit to a proper hospital for treatment should be made to aid recovery.

The part of the Band-aid that contacts the wound is made of non-woven fabric sponge, which serves to absorb exudate and keep the wound dry. The Band-aid itself does not have anti-inflammatory properties; after an injury, the standard treatment should be to take antibiotics.
