In life, we often use band-aids, especially small wounds. There is a bit of blood. It is often thought that it would be all right to stick a Band-Aid. This is actually wrong.
Band-Aid, also known as "Hemostatic plaster." Generally, it can only be used for small wounds that are superficial, clean and with neat wounds, and have little bleeding and do not require suturing, and can temporarily stop bleeding and protect the wound. However, due to the poor water absorption and ventilation of Band-Aid, it is not conducive to the drainage of wound secretions, which is beneficial to the growth and reproduction of bacteria and makes the wound and the surrounding skin white and soft, resulting in secondary infection. Therefore, the use of Band-Aid should not be used for a long time. Too long. If after 24 hours, the wound is found to have abnormal conditions such as fever, pain, swelling, etc., it should be considered that the infection may have occurred in the wound and should go to the hospital immediately for disinfection and anti-infective treatment.
In addition, many people directly cover the wound with a band-aid, which is absolutely incorrect. It can easily lead to wound infections. The correct method is: first clean the wound (preferably with 3% hydrogen peroxide rinse), and then apply a band-aid. If the skin damage is relatively deep and the site is unconditionally treated, you may wish to rinse the wound with clean water first, and then use Band-Aids for simple dressing. At the same time, you should seize the time to the nearest hospital for regular disinfection to prevent infection. In addition, the band-aid can not be wrapped too tightly, so as to avoid anaerobic infection caused by the wound is not airtight, too tightly wrapped around the injured part of the blood circulation is also easy to cause ischemic necrosis.
Moreover, Band-Aids are not universal stickers and cannot be used in the following situations:
1. After being bitten by animals (eg, cats, dogs), bandages should not be used for bandaging. Should first wash with soapy water several times, then use iodine, alcohol to disinfect the wound, expose the wound, and inject the rabies vaccine.
2. Those who have serious wounds and have wounds should go to the hospital for treatment. Don't use band-aids until the wound has been debrided. Contaminated or infected wounds and wounds with secretions or pus can not be used.
3. Deep and narrow wounds, such as nails, knife tip injuries, etc., cannot be bandaged with bandages. After the hemostasis, the wound should be exposed to prevent tetanus-infected wounds. If necessary, tetanus serum should be injected under the guidance of a doctor.
4. Burns, burns, exudates, and exudates can not be labeled with band-aid to prevent poor discharge and secondary infection.
5. If the band-aid attached to the wound is soaked in water, replace it immediately. This is especially important when outdoors. Because Band-Aid's water-absorbing ability is very good, if it is ignored, the wound is equal to being directly soaked in water, which has become a breeding ground for bacteria. Nowadays, although a waterproof band-aid has appeared on the market, the effect is not obvious, especially in the joints of the hand that are most easily injured in outdoor activities, and the waterproof performance is not fully reflected.
