Nope. Futile, expensive and dangerous care is just that. Futile, expensive and dangerous. EMS has got to get away from the "try to save everyone" mentality.
Unfortunately, due to many protocols around the country (my area included), CPR is to be started on EVERY patient, unless there are injuries incompatable with life, or lividity/rigor have set in. So if I have a pt such as the one in the OP, I am to start CPR, or else my toosh will be on a silver plater. Unless, of course, but "stuff," it meant brain matter (but that's covered under 'signs incompatible with life').
To the OP, I have a few kind words of advice.
1) On this forum, and in real life in general, remember to be very specific. People in real life and on this forum will chew you up and spit you out if you aren't to-the-dot specific. (Trust me, I know
) That isn't necessarily a bad thing, but if you want true and honest advice and support for these calls, you need to list everything just the way it is, as long as it doesn't violate HIPPA.
2) Unless you have a jump bag in your POV, don't stop. There's nothing you can do, except call 911. Especially since you didn't have anything, I would assume that would mean you didn't have gloves, and for a trauma, no gloves is a big No-No.
3) You had a blank moment. I'm going to pass on some advice to you that was given to me. This moment doesn't define you as an EMT. Many people in EMS will have a moment that makes them stop in their tracks. I agree with other people in that you didn't seem to do a proper size-up, and seemed to disregard scene-safety. But you jumped into a situation where you didn't have a partner by your side to help shake you from your freeze. Don't let this call define your career. And if you continue to have moments like this when you freeze up and can't function on your own, perhaps then you should reconsider another field.
If you ever want to talk one-on-one with anyone, there are plenty of open and welcome PM boxes, mine included. Don't lose sleep over this one. It happens.
