Initial bleeding often serves to flush foriegn objects introduced by the initial trauma. People see blood and want to apply hydrogen peroxide, alcohol, betadine or any number of petroleum based salves in gross amounts ( more is better.) Then the poor professional has to deal with the mess, inflicting further pain and trauma to the wound site just to see whats going on. On non lfe threatening wounds I let it flow briefly, apply pressure when appropriate until coagulation and then loosely bandage.This stuff is like an old cutters snakebite kit. I see well meaning people overwhelming paper cuts while unobserved internal injuries or even shock go unnoticed.
