Tetanus is caused by Clostridium tetani, which settles in the human body through mucous membranes and wounds, producing spasm-inducing neurotoxins that affect the body's muscle groups, particularly the masseter and respiratory muscles, leading to the ceasing of respiratory circulation and endangering life. Therefore, for patients with deep wounds, heavily contaminated wounds, and extensive open fractures, it is essential to administer tetanus antitoxin treatment. If the wound is superficial, clean, and dry, the patient may consider forgoing tetanus antitoxin treatment under the condition of proper wound debridement and dressing changes. However, for patients with large wound areas, deep and severely contaminated wounds, and those whose wounds are not redressed timely, it is crucial to administer tetanus antitoxin treatment.
