Wounds that are more than 12 hours old can be sutured, depending on the specific site as well as the depth of the wound and the skin defect to decide. If the wound is relatively small and superficial, it can be closed without sutures after more than 12 hours, the bacteria inside the wound is more, the inflammatory infection of the wound is heavier, and the wound can heal on its own through open dressing changes, and the scar is not particularly obvious. If a wound in an important area, such as in the face or neck, or even if the wound is very large, it can also be sutured if it does not heal properly without sutures. Before suturing, the wound should be thoroughly debrided with hydrogen peroxide and saline, and the internal necrotic tissue should be removed, then disinfected with iodophor, and after disinfection, the wound should be intermittently sutured, and after suturing, systemic intravenous antibiotics should be applied to prevent wound infection.
