Tetanus antitoxin still need to hit?

At present, tetanus antitoxin is widely used in clinical practice. Whether it is necessary to fight depends on the degree of injury of the patient. If the patient is only superficial injury, such as skin abrasion, only local disinfection is needed at this time. There is no need to inject tetanus antitoxin. On the other hand, if the wound is deep, such as being cut by a sharp knife, etc., cutting subcutaneous tissue or even muscle tissue, such a relatively deep wound may cause Clostridium tetani infection to produce exotoxin, causing the patient to show tetanus related symptoms. At this time, it is recommended that the patient seek medical attention in time to inject tetanus antitoxin to prevent tetanus infection.
