Stitches are usually needed when there is a complete separation of both skin layers. This is when the edges of the skin do not fall together and the wound is larger than 1–2 centimeters. If this is the case stitches are needed to close the wound.
If you anticipate a delay in getting the person to the hospital, use “butterfly” adhesive strips to help keep the skin flaps together. Apply dressings over top and bandage as normal.
