Whether to fight or not depends on the depth of the wound. The deeper and dirtier the wound, the more suitable it is for the growth and reproduction of tetanus Bacillus, and the more opportunities there are for tetanus.

If you just graze the epidermis and the wound is not deep, you only need to do proper debridement or wipe it with disinfectant such as mercuric chloride, and you don't need to inject tetanus antitoxin. But if the wound is deep, or the wound is polluted by pollutants such as dirt and iron embroidery, it must be beaten. Because tetanus Bacillus mostly grows in soil and rust, tetanus antitoxin should be injected when the wound is deeply polluted by soil or stabbed by rust. And it is best to get a tetanus shot within 24 hours;

If the scraped skin has a large opening and a wide contact area with air, it can be decided as the case may be. If you don't trust, you'd better make one.
