Tetanus antitoxin is generally administered via intramuscular injection, commonly in the buttock muscles. If a patient is injured by a rusty iron object, and the wound is small and deep, it is generally recommended to consider administering tetanus antitoxin actively within 24 hours after the injury to help prevent tetanus. Additionally, for local wound care, the patient needs to rinse the wound with soap and water under running water, then clean, apply, rinse, and dry with hydrogen peroxide before disinfecting with iodine. Afterwards, covering the wound with sterile Vaseline gauze and sterile dressings is appropriate. Furthermore, the patient should keep the wound dry for up to three weeks after the injury as getting it wet may delay healing or increase the risk of incisional infection. Moreover, the patient should avoid alcohol and minimize the intake of spicy and irritating foods within a month after the injury.
