Good quality skin closure strips. Very handy for gaping wounds. Make sure wound has been washed with sterile water if possible, drinking water if sterile is not available. Clean around the wound with alcohol, not allowing any alcohol into the wound itself. Allow skin to dry and fix the strips to the skin on one side of the wound. Pull the wound closed gently and firmly press the other end of the strip down onto the skin to close the wound. Pad over with a sterile gauze or similar, then be sure to bandage the area if possible.
