There is a myth in EM that "when you're off, you're off." Not so. Exhibit A: brk81144's post, above.
You definitely don't want bring it home to your kids, but your spouse is going to feel it. There's no way around it, and they need to understand the stuff you deal with, isn't what people with regular jobs deal with. Some of the unspeakable tragedy we see can't be "shaken off" like a bump to the knee. Though I'm sure banking, lawyering and accounting can be very stressful, it's not the same as what we, police officers, coroners, or soldiers see. You cope with it the same way you try to cope with any other inexplicable tragedy. You talk about it with your significant other (HIPAA details removed, of course), friends and co-workers that were also involved, or with spiritual beliefs, if you have any. There's a certain amount of pain, mourning, or greiving that's going to have to happen, especially with Peds cases that hit close to home, even if it's only a short time. (Why do you think I post cases that are from years back, yet seem as vivid as the present and still haunt me, ie "
Those Shoes"?) I call it "PTS
EDD" or "post traumatic stress emergency department disorder," only half tongue in cheek.
Does it get easier? To some extent yes, because you build up some emotional armor to it all. But you can't be totally detached, and every once in a while one will find that weak spot in the armor and draw blood. So you go home, you give your spouse and kids (and dog and cat) an extra kiss and hug and remind yourself how thankful you are for what you have, and that it wasn't you, or them. You also remind yourself how great of a job you're are doing by just being there to help when able and even when unable, because most others couldn't even stomach what you're doing or seeing for one minute. Also, I think it helps to let families see your pain a little during death notifications and see that it hits home with you, too. There's nothing worse than a doctor who doesn't seem to care that the tragic news he just dropped, amounts to a nuclear bomb on their life. What you are going through, everyone goes through. It's normal. It'll get better.
