Open soft tissue injuries mainly include open muscle injuries, open nerve injuries, and open vascular injuries and other serious lesions. Patients will show severe local bleeding, swelling, pain, and limited movement, and numbness, reduced blood supply, coldness, and even ischemic necrosis can occur in the peripheral part of the injury. Therefore, if an open soft tissue injury is diagnosed, the best time is within six to eight hours for prompt debridement and treatment. The patient can recover best by repairing the above soft tissues through debridement surgery treatment within six to eight hours. At the same time, tetanus should be injected promptly 24 hours after the injury to avoid complications. If more than six to eight hours, the risk of secondary infection is increased and even after debridement surgery, the patient may still develop fever and localized septicemia, sometimes requiring multiple debridement surgeries to repair.
