If there is a break in the skin after a fall or abrasion, the skin should first be sterilized with vital iodine. If the skin comes into contact with unclean substances such as rust, dirt, bricks, etc., a tetanus shot should also be given to avoid tetanus infection. Once these substances contain tetanus bacillus and the body is infected with tetanus bacillus without timely tetanus antitoxin, tetanus infection is highly lethal, so tetanus shots must be given. If you fall on a relatively smooth, clean surface such as tile, resulting in broken skin, you may not need a tetanus shot. Tetanus bacillus generally likes to parasitize and multiply in anaerobic environments. If the soft tissue of the skin is severely damaged, it is recommended that Bactroban ointment be used externally or that a cephalosporin or penicillin anti-infective injection be given for anti-infective treatment. If the skin is not damaged, just ordinary soft tissue abrasions, sprains, do not need special treatment, you can rest, and after the swelling subsides, you can slowly ease.
