Generally speaking, any department in a hospital can administer a tetanus shot, but patients who receive tetanus shots usually have injuries. The majority of these patients are sent to the emergency department, where nurses, based on the specifics of the patient’s wound and upon a doctor's assessment, will first clean the wound and then administer the tetanus shot promptly, often opting for either tetanus antitoxin or tetanus immunoglobulin. Of course, this depends on the patient's age and immune status, and their past immunization schedule. Most patients, if the skin test is negative, receive tetanus antitoxin, which typically provides immunity for about 3 days. If the skin test is positive, tetanus immunoglobulin is administered, which can last about 3 weeks. For periods exceeding this, if there are again high-risk infection factors, a timely preventive injection treatment should still be administered.
