Whether the hand is scratched by the iron need to play tetanus needs to depend on the depth of the wound, if the wound is deeper, it is necessary; if the wound is shallow, it is not necessarily necessary.
1. Deeper wounds: If the depth of the wound is deeper, the dermis or fascial tissue has been injured, plus the wound surface is narrower, so it is easy to have an anaerobic environment inside, and the tetanus bacillus is very likely to multiply and grow in large quantities inside, which leads to infection, and it is recommended that the patient receive tetanus vaccination promptly within 24 hours.
2. If the wound is shallow: If the wound is shallow, the wound is completely exposed to the air and there is no anaerobic environment, then there is no need for tetanus vaccination and the chance of infection is low. Most patients only need to use povidone-iodine, alcohol and other good wound disinfection and bandaging work can be.
If your hand is cut by iron, it is recommended that you go to the hospital in time to see a doctor to determine whether you need to take a tetanus shot, so as not to delay your condition.
