Band aid is one of the essential first aid products for almost every family, but recently, this "universal paste" has caused a big disaster. However, there was a girl who had amputated her limbs because of the wrong use of band aids, so do not use band aids indiscriminately. Under what circumstances can we not use band aids?
Clinically, orthopedics and emergency departments often treat some cases of wound infection caused by the wrong use of band aids. Although not to the point of amputation, there are many patients with delayed wound and ulceration. Unfortunately, people have not paid attention to the misunderstanding of band aids.
Band aid for small and shallow wounds
In general, band aid is mainly used for some small and shallow wounds, especially for the incision neat, clean, less bleeding and no need to sew, such as knife cut, cut, glass scratch, etc.
You can't use band aid in the following 7 situations
A small, deep wound. Small and deep wounds can be pasted, which is not conducive to the discharge of secretion and pus in the wound. It is easy to make bacteria grow and multiply, cause or aggravate infection, especially easy to infect anaerobic bacteria such as tetanus.
Burns. Skin ulceration and running water after scald can not be treated with band aid, otherwise secretion will promote infection.
There are foreign bodies in the wound. If there is a foreign body in the wound, the bandage should not be applied immediately. Instead, the bandage should be applied after debridement or removal of the foreign body in the hospital. Some wounds are seriously polluted and even infected, so we can not use band aids to cover the wounds, otherwise it will cause or aggravate the infection.
Injured by a nail. If your fingers or toes are injured by nails or blades, especially when there is rust on the nails or blades, you can't simply bandage them with band aids. Be sure to clean first, then keep the wound exposed to prevent infection, and get tetanus vaccine to the hospital as soon as possible.
● animal scratch and bite. If the wound is scratched and bitten by animals, if the band aid is used, the bacteria will accumulate or spread in the wound. Therefore, whether it is bitten or scratched by pets at home or small animals outside, you should first wash it with soapy water for several times, and then disinfect it with Iodophor to expose the wound, and then inject rabies vaccine into the hospital.
All kinds of skin boils. Band aid is not conducive to the absorption and drainage of pus, but conducive to the growth and reproduction of bacteria. Therefore, band aid cannot be used for furuncle.
Allergic to adhesive tape. People with a history of adhesive allergy are not uncommon in clinic. The specific manifestations are pruritus, redness and many small blisters on the skin where the adhesive is applied. Therefore, people with allergic history of band aid or adhesive tape should choose other hemostatic methods, or choose special anti allergic adhesive tape.
How to use band aid correctly
1. Simple disinfection before pasting.
Many people's first thought after being injured is that the wound can't be stained with water, so they don't do any treatment for the wound. They directly stick band aids. They think that the drugs in the inner layer of band aids can play a role in disinfection.
In fact, before using a band aid, you should first check whether there is dirt in the wound. If there is anything unclean, you should use sterile normal saline to clean the wound first, and then stick the band aid. If the wound is pierced by nails and other objects and is relatively deep, you should go to the hospital immediately for treatment, and need to inject tetanus antitoxin at the same time.
2. Change the band aid at least once a day.
After opening the band aid package, avoid polluting the drug surface. When applying, the medicine surface must be aimed at the wound, and then slightly press on both sides of the wound. When using band aids, pay attention to:
One is to observe the changes of the wound at any time. If there is a pulsatile pain similar to the pulse at the wound or secretion overflows, it should be opened 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 by a doctor immediately.
Second, to protect the wound, do not often pinch the wound with your hand, the local wound as little activity as possible, to prevent collision, so as not to split the wound.
Third, the use of band aids should not be too long, at least one change a day.
3. Don't stick your fingers in circles.
Many people are used to putting band aids around their fingers after they get injured. In fact, it is dangerous to use band aids on fingers and toes. If the bandage is too tight, it is easy to cause the blood flow of fingers and toes is not smooth, and the wound healing speed is slow. Suzhou 4-year-old girls belong to this situation, the band outside the cloth, cattle tendon affect the blood circulation.
4. Use a band aid with medicine. Be careful of allergies.
Generally speaking, band aids with and without drugs have almost the same effect, but those with drugs can cause allergies. After sticking band aid, if you feel burning, stop using it immediately.
5. It is valid for 3 years.
Take a look at the outer package before use. If the band aid has been used for more than 3 years, it cannot be guaranteed to be sterile. Once it has expired, it should be thrown away as soon as possible.
6. Gauze is more reliable than band aids.
If it is not an emergency, gauze should be used instead of band aid. Compared with band aid, gauze is more breathable and absorbs exudate, which is not easy to cause local moist and infection. It is to take gauze that is slightly bigger than the wound 1 ~ 2 cm, cover the wound after applying medicine, and then wrap it with breathable anti allergy adhesive.
Try to keep the wound in a clean and dry state. If the gauze used to bandage the wound is contaminated or soaked in water, it should be replaced in time. After disinfection of the wound, it should be bandaged again. If there is swelling, pain and exudation, it means that there is infection and it should be treated in the hospital.
