Tetanus is an acute infectious disease caused by the invasion of broken skin by Clostridium tetani. Since tetanus injection is divided into tetanus antitoxin and tetanus immunoglobulin, so we should pay attention to the skin test before tetanus injection, and after injection, we should pay attention to the affected area to avoid getting wet, pay attention to the diet, and avoid strenuous exercise and other matters. 1. Skin test: Since everyone’s constitution is different, so if you are injecting tetanus antitoxin injection, you need to carry out skin test first to prevent allergic reaction after injection. 2. Avoid getting water on the affected area: Since there will be small wounds after the tetanus injection, at this time, you should avoid letting the wounds and injection site get wet to avoid infection. 3. Pay attention to the diet: after the tetanus shot, we should pay attention to a light diet, avoiding spicy and stimulating food, seafood, hair products, tobacco and alcohol, in order to avoid stimulating the activity of antitoxin and affecting the patient’s immune function. 4. Avoid strenuous exercise: avoid strenuous exercise after tetanus shot, so as not to involve the wound and re-infection, which is not conducive to the recovery of the body. After the tetanus shot should be closely observed to avoid the occurrence of redness, swelling, pain and other phenomena, if the body has discomfort, it is recommended to consult a doctor in a timely manner.
