how to treat injuries to accidents?

hi all steemian friends
on this occasion I will share my experience a little about how to deal with a patient with a torn wound case.
the first way is to ascertain whether the wound is bleeding great or not, then the value of the wound and the condition in it. need to sew or not. if the wound in it should be in sewing as in this picture.

if if not, then the wound is sufficient to be provided with Nacl then closed.
if you want to know more please vote and comment, thank you
