Fibrin glue and plasminogen. This glue can be used for repairing dura tears, bronchial fistulas and for achieving hemostasis after spleen and liver trauma. It is also employed in "no sutures" corneal transplantation, pterygium excision with amniotic membrane or conjunctival autograft, and in ocular trauma for corneal or conjunctival defects. It can also be used for skin graft donor site wounds to reduce postoperative pain.
