Band aid is a common surgical medication in life. It has the functions of hemostasis and wound protection. It can compress and stop bleeding, protect wounds, prevent infection and promote wound healing. It is small, simple and convenient to use. But not all wounds use band aids, which can not be used in the following cases. Under what circumstances can I not use band aids?How to use band aids:
1,When the wound is relatively large
Bandage gauze can not completely cover the wound. Adhesive tape attached to the wound can affect the speed of wound healing. Especially when replacing the band aid, the wound may be torn and the wound area may be increased. In addition, the wound under the tape is prone to infection or allergy.
2,When the wound is deep
If the wound is stabbed by a knife tip or a rusty iron product, stop bleeding first, then disinfect the wound part, and go to the hospital to inject tetanus vaccine in time.
3,When the wound is contaminated
When the wound is contaminated, first go to the nearest hospital for thorough debridement or remove the foreign body, and then do simple dressing. If there is infection, you can’t use band aid.
4,Allergic to tape
Some people with allergic constitution are allergic to the adhesive tape of band aid. When using band aid, there may be skin redness, swelling, itching or small blisters, which is easy to cause infection.
5,When burned or scalded
When the skin is burned or scalded, the use of band aid may lead to wound surface infection. If you are accidentally scalded by heat, cool it with cold water first, and then apply the scalded ointment. If the condition is serious, you must go to the hospital for treatment in time.
6,Furuncle of skin
Band aid can affect the absorption and drainage of pus in furuncle, which is suitable for bacterial growth and reproduction. In the early stage, 75% alcohol can be used to disinfect the local application, or warm water can be used to rinse. If you have systemic symptoms, you need to go to the hospital for treatment.
7,Injured by animals
After being bitten or scratched by an animal, if you stick a band aid, it may spread bacteria in the wound and cause infection. In this case, you should wash the wound with soapy water first, and then go to the hospital to inject rabies vaccine.
If a diabetic attaches a band aid, it will increase the local temperature, plus the wound patch is airtight, which is suitable for bacterial propagation, causing serious wound infection and prolonging the healing speed of wound.
Band aid is not a panacea and is not suitable for all trauma situations. Try not to stick band aid and go to the hospital for examination and treatment in time. Check whether there is dirt in the wound before using the band aid. If there are unclean objects, clean the wound with sterile normal saline first, and then stick the band aid. In addition, pay attention to the place of the wound.
After using the band aid for 24 hours, the wound consciously has pain similar to pulse beating or secretion overflow. It is necessary to open it in time to observe whether there is redness, swelling, heat and pain around the wound. If yes, it means that the wound has been infected and should be treated in hospital in time.
