Band-aids are one of the essential first-aid medicines in every household, but many citizens do not know the correct way to use them. Here are a few common misconceptions about their usage:
Misconception 1: Band-aids are a universal remedy
Band-aids are not a universal remedy and cannot be used for all kinds of injuries. Generally, they are mainly used for small and shallow wounds, especially cuts that are neat, clean, with little bleeding and do not require stitches, such as knife cuts, slashes, or glass scrapes.
Correct approach: Strictly adhere to the indications. For larger, deeper wounds with foreign objects, band-aids should not be used; in such cases, seek medical attention immediately. For contaminated or infected wounds, such as severe skin abrasions or burns, band-aids should not be used. As for folliculitis, boils, purulent infections, and various skin diseases, band-aids are also inappropriate.
Misconception 2: Band-aids can be applied casually
When using band-aids, we often prioritize convenience and apply them carelessly, which is incorrect.
Correct approach: Before applying a band-aid, check if there are any contaminants in the wound. If there are unclean substances, clean the wound with sterilized saline solution before applying the band-aid. If the wound was caused by a deep puncture from a nail or similar object, seek medical attention immediately and receive tetanus antitoxin injection. Also, after opening the band-aid, avoid contaminating the medicine surface. When applying, ensure the medicine surface aligns accurately with the wound. After application, slightly press on both sides of the wound.
Misconception 3: Band-aids can be left on for long periods
Just because the wound has a band-aid on it does not mean everything is fine, nor should it be left on for extended periods without attention.
Correct approach: First, observe the changes in the wound. If 24 hours after applying the band-aid, there is a "pulsating pain" around the wound or secretions overflow, open and check if there is redness, swelling, heat, or pain around the wound. If so, the wound is likely infected, and you should consult a doctor immediately. Second, protect the wound. After using a band-aid, avoid frequently touching or pressing the wound, minimize movement in the area, and prevent collisions to avoid splitting the wound. Third, do not keep the band-aid on for too long; it should be changed daily.
Misconception 4: Waterproof band-aids are completely waterproof
Using waterproof band-aids does not mean they can withstand prolonged water exposure. If the band-aid is not tightly adhered to the surrounding skin, especially in special areas like fingertips, knees, or elbows, even "waterproof" becomes ineffective.
Correct approach: When using waterproof band-aids, try to minimize contact with water, observe and protect the wound, and promptly replace any band-aids that become wet.
