We often encounter or encounter this or that small injury in life, because the wound is small or feel insignificant, we usually choose to bandage it ourselves, what will you think of at this time? Band-Aids, yes, it is always necessary. But, is a small band-aid really a panacea? Can they really guarantee the safety of our wounds? First, let’s understand Band-Aids! Band-Aid is also called benzalkonium chloride patch, commonly known as “hemostatic ointment”, mainly composed of adhesive tape and absorbent pad, with hemostatic and creative protection, can absorb the exudate of the wound and play a role in drying the wound; it does not have anti-inflammatory and sterilizing effects, because of its poor permeability, there is a possibility of inducing infection. It is suitable for small wounds with superficial wounds, neat and clean wounds, little bleeding and no need for suturing. Secondly, how to paste is correct? If it is a small wound, many people may put the band-aid directly on the wound, in fact, this practice is completely wrong. Because the injured area is likely to have been contaminated or foreign bodies, so it must be treated before it can be pasted. 1, a lot of sterilized water or saline rinse the wound, if not also water rinse. 2.After rinsing, gently remove the dirt or foreign matter from the surface and deep part of the wound. 3, again a lot of sterilized water or saline rinse the wound surface, deeper wounds need to use hydrogen peroxide again rinse 2 times. 4.Wipe the wound with a cotton ball dipped in complex iodine or 75% alcohol disinfectant, and disinfect the wound 3-5 cm from the outer edge of the wound, gradually disinfecting the wound from the outer circumference to the inside of the wound 2 times; do not casually apply purple potion or other drugs. For the skin mucous membrane or children’s delicate skin is not suitable for alcohol disinfection, prone to stinging or burns. 5.After the wound surface is slightly dry Band-Aid dressing wound. Single person with one hand can first paste the health, and make the absorbent pad central to the trauma bandage; single person with two hands can first absorb the pad central to the trauma bandage. If the wound bleeds a little more, you can put pressure on the bandage. Please note: When removing the paper from the surface of the band-aid, do not touch the absorbent pad with your fingers to avoid contaminating it and reducing the possible infection factor. Third, which wounds are not easy to apply Band-Aids? 1, large or deep wounds: the wound is significantly larger than the width of the absorbent pad of the Band-Aid, the wound is too large Band-Aid can not completely cover the exposed part of the wound is prone to infection, even if the paste two or more, due to cross-use is still prone to infection; depth greater than 0.5 cm should not be used, too deep wounds prone to anaerobic bacterial infection, common as tetanus bacillus is this category. 2, has been infected or septic wounds: If the wound is not the first time effective disinfection, infection is likely to have occurred, there will be redness or exudate around the wound, and even some wounds have been septic, at this time the use of Band-Aids has been inappropriate, easily leading to more serious infections occur. Professional surgeons are needed to deal with before dressing. 3, animal bite wounds: wounds or bites and other wounds caused by animals, do not use Band-Aids to avoid the accumulation or spread of venom and germs in the wound. In the first instance, the wound should be rinsed with water, purified water, saline for more than 15 minutes or 2% soapy water, hydrogen peroxide or 75% alcohol repeatedly for at least 5 minutes. 4, boils, heavy pollution or burns trauma: skin follicle infection, heavy pollution or burns trauma, because the absorbency and breathability of Band-Aids can not meet the requirements of such wounds wound healing, but conducive to bacterial growth and reproduction aggravate the infection. Fourth, the Band-Aid paste a few days good? We often see many people do not change band-aids for several days or band-aids have been very dirty has not been changed, in fact, the normal band-aid replacement time should not exceed 24 hours, and for the possibility of contamination of the wound we should immediately disinfect the band-aids after replacement, each time before replacing the band-aids should be disinfected again after the wound before replacement. Finally, Band-Aid is not a panacea, when the wound is not suitable for Band-Aid treatment, we should choose sterile gauze or clean towels and other preliminary dressing wound immediately after the nearest hospital related departments to take formal disinfection, dressing treatment, and receive tetanus vaccine or other vaccinations to prevent serious complications occurring due to improper wound treatment.
