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, low 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.
