Deeper stab wounds should be further surgically explored and, if necessary, supported by general anesthesia. Deep wounds are also prone to tissue and organ damage, and some patients may show signs of internal bleeding and decreased blood pressure. Dilated exploration is performed to clearly identify the bleeding point, and in severe cases, combined organ resection is required if necessary. If significant vascular nerve injury is found, anastomosis should be actively performed if the condition permits, to avoid adverse injury to the relevant organs and complications, and to prevent infection and complications after surgery. As for those caused by trauma, refined tetanus antitoxin injection should be injected promptly after the injury. For patients with combined fractures and vascular nerve injuries, effective immobilization and elevation of the limb are also needed to prevent thromboembolic complications.
