Often wounds that are dirty, deep or caused by rusty metal require a tetanus shot. Tetanus bacillus is an anaerobic bacteria that is usually found in dirt, rusty iron and other dirty environments. Patients with cuts that have dirty wounds with dirt and other debris mixed in the wound need a tetanus shot. Tetanus vaccination is recommended for cuts, large deep wounds or small but deep wounds. Tetanus vaccination is also recommended for cuts made with rusty iron or other metals. After a cut, the wound should be debrided in a timely manner to remove any debris left in the wound, and then disinfected and bandaged. In daily life, the wound should avoid contact with water to avoid infection. The patient should be treated promptly after being cut and take good care of the wound to avoid infection and inflammation.
