Band aid is one of the necessary first aid medicines for every family, but many people do not understand the correct use of band-aids. The following are some common misunderstandings.
1. Band aid is a panacea
Band aids are not a panacea and are not suitable for all wounds. Under normal circumstances, band aids are mainly used for some small and shallow wounds, especially for cuts that are neat, clean, have little bleeding and do not require sutures, such as knife cuts, cuts, and glass scratches.
Correct approach: Strictly grasp the indications. For large, deep wounds with foreign bodies, it is not advisable to use band-aids. In this case, you should go to the hospital in time. For wounds that have been contaminated or infected, such as heavy skin abrasions, burns and scalds, it is not appropriate to use band-aids. For folliculitis, boils, purulent infected wounds and various skin diseases, it is not suitable to use bandages. For wounds caused by dog bites, cat scratches, snake bites, poisonous insect stings, or bites, do not use band-aids to prevent the accumulation or spread of venom and germs in the wound. In the first time, wash the wound repeatedly with water, cold tea, mineral water, normal saline, 2% soapy water, etc., for more than 15 minutes.
2. Band-aids can be applied casually
When using band aid, it is always convenient to put things on casually. This is not correct.
Correct way: Before using the band-aid, first check whether there is any dirt left in the wound. If there is any dirt, clean the wound with sterile saline first, and then apply the band-aid. If the wound is pierced by iron nails and other objects and is relatively deep, you should go to the hospital for treatment immediately and need to be injected with tetanus antitoxin. Secondly, after opening the bandage, avoid contaminating the surface of the medicine. When applying, the surface of the medicine must be aligned with the wound, and pressure should be applied to both sides of the wound after it is applied.
3. Band-aids can last for a long time
Placing a band aid on a wound does not mean that "everything is going well", nor can it be left on and ignored for a long time.
The correct approach: First, pay attention to observe the changes in the wound. If 24 hours after using the band aid, the wound feels "pulsating pain" similar to pulse beating, or there is discharge of secretions, open it in time to observe whether there is redness, swelling, heat and pain around the wound. If so, it means that the wound has been infected and should be treated by a doctor immediately. The second is to pay attention to protecting the wound. After using the bandage, do not often pinch the wound with your hands, and move as little as possible in the wound area to prevent collisions to prevent the wound from opening. Third, the use time of band-aids should not be too long, otherwise bacteria will grow, and should be changed once a day.
4. Waterproof band-aids are not afraid of water
It is not that the waterproof band aid can be in contact with water for a long time. If the band-aid does not stick tightly to the skin around the wound, especially in special areas such as fingertips, knees and elbows, the waterproofing will not become "waterproof". The correct approach: When using waterproof band-aids, try to minimize contact with water, pay attention to observe and protect the wound, and promptly replace the water-soaked band aid.
