Tetanus is usually cured within 2-3 weeks after an attack if it is treated aggressively and effectively, but it may not be cured in some severely ill patients. Tetanus patients can usually be cured in about 2~3 weeks if they receive timely, active and effective treatment under the guidance of doctors, such as surgical debridement, injection of tetanus antitoxin or immunoglobulin, effective antibiotics (e.g., triple cephalosporin, ornidazole, tinidazole) to kill or destroy Clostridium tetani, and active prevention and treatment of complications. However, some tetanus patients have rapid onset of disease, short incubation period, or tetanus occurs on the basis of deep puncture wounds, severe burns, open fractures, gangrene, etc., the condition will be more serious, and there may be muscle spasms, pulmonary atelectasis, cardiac failure, pulmonary embolism and other serious complications leading to the death of the patient. Therefore, tetanus antitoxin should be injected promptly after injury to prevent tetanus. Tetanus patients should go to regular hospitals immediately and actively cooperate with doctors in order to achieve the goal of curing the disease and avoid delays.
