I know Cavalier says he won't respond to this, but I think it's a good point for others out there.
1. I don't agree with the argument that "I've been in the real world, so you can't judge me." When you join a group (ambulance service, the Army etc) you start off with your own values and ideas of how things should happen. Gradually you learn what is accepted behavior, attitudes, and views in that group and most people come to conform to some degree with these common values. Often when you've been doing a job for awhile there are things that you have come to accept as normal parts of the job that it takes an outside perspective to realize, "hey, maybe this isn't right." You really don't years of experience to be able to say that inflicting more pain than is medically needed because you don't like a patient is unethical.
2. I understand the argument that you may not go out of your way to help patients who you don't like. Okay, I'll agree with that. Sure I won't stay 20 minutes past my off time to find a pillow for the patient who just spit on me. But there is a difference between that and making an IV hurt as much as possible before you start it.
3. Any procedure caries some risks, and if you are doing it with a goal other than finishing the task safely you are doing harm. "Fishing around" with an IV cath damages tissue, increases the risk of infection, blowing the vein, delaying having a patient line etc. So you are doing harm.
4. Who are you to judge your patients? Maybe the guy arrested for DUI is really a diabetic, maybe the person accused of child molestation is innocent. You don't know and the reason why you treat patients professionally is so you don't have to find out. It's not your job. Also it's a slippery slope for causing a little more pain to maybe not giving pain meds for a fracture. Or why don't you just say you won't treat prisoners? Or certain groups you don't like? Once you get on that road where you give people different care based on who they are there is not easy stopping.
Even though I don't think you need to match someone in experience to say they are wrong about ethics, and I don't feel the need to fluff my ego by rattling off my experiences, I'll just say that I've worked in EDs, I've worked 911 on ambulances. I'm a medical student and yeah, I have patients I don't like. So I don't think I'm talking from an ivory tower to say trying to cause more pain than needed because you disaprove of a patient is wrong. I'm not saying anyone shouldn't be in medicine, or that you are a bad care provider. I've met plenty of people who have no problem wacking a patient in the head with a radio if they are being a jerk. But I think as professionals we can hold ourselves to a higher standard.
Let me say that I've been working in EDs for the last nine years, and was a full time EMT on a 911 ambulance for almost two years so
