There is one more tactic you can use, calling medical control and advising them of the situation releases you from a liability if that is what everyone is worried about. Having a doctor or whomever try to talk some sense into your patient really helps out a lot ,but I agree that there is some psychological problem ,and could be due to shock of the whole incident but ,if the law can not talk him into it and or medical control ,there is really nothing you could do ,although he could make an argument that he never gave you permission to treat him at the very beginning . That's why EMS is sometimes a very unforgiving job . You did your best and thought of your patient not much else you can do
