Whether the patient stepped on a nail needs to play tetanus, based on the different degrees of cleanliness of the nail, the severity of the patient’s local soft tissue injuries, and whether the patient is actively wound disinfection and other factors to make an objective analysis, mainly as follows: 1, if the patient stepped on a nail local injury is very superficial, and no active bleeding, only accompanied by damage to the cuticle, the nail is very clean, the patient was injured in a timely manner using hydrogen peroxide, vital iodine, and The trauma surface is repeatedly cleaned with hydrogen peroxide, vital iodine, physiological saline, the trauma surface reaches a relatively sterile environment, and the trauma surface can be completely healed in 24-48 hours after sterile gauze dressing, without the need for tetanus antitoxin injection. 2, if the patient was nailed deeper, accompanied by dermal layer damage as well as local active bleeding, the nail is accompanied by rust. This time the patient was not timely wound disinfection treatment after injury, the trauma surface is easy to form an anaerobic environment, the patient needs timely injection of tetanus antitoxin, tetanus immunoglobulin to prevent tetanus infection.
