I have gotten more fucked up by people's reactions than the actual incident.
I tend to agree with the Sherrif of Baghdad about PTSD. Its what happens immediately after that matters, and I'm not talking about a CISD. I mean right there in the parking lot and at the base when were hosing brains out of our gear.
John would make sure everyone told that person they did exactly what they were supposed to do in that situation, the way you feel is normal, now let's go take this apart and see where I failed you, son.
My version was "That was a real one, how you doing with it? When we get this wrapped up we're gonna take it completely apart and look at it, but for right now tell me what you did right and why you did it..." that turns into what anyone that ever worked with me knows as the 3 questions- what did you do right, what did you do wrong, what would you do different next time?.
The last question would take us over to the dry erase board and we'd run the call again, and again, and again, until they had a road map that they themselves created and a belief that they absolutely can do that one again when it comes.
When I had my first dead baby I wasn't working for a very "healthy" dept.
A medic from a county over got my number and called me out of the blue. We weren't friends, just a face I knew.
He talked me through it, because he knew it was a possible go/no go for a young provider.
Best thing he said to me was "this wasn't your fault, you didn't create the situation. He was dead before they called 911, you never had a chance on this one. But it gave you something valuable, it will never be your first time again.. it will never be that scary again. You've already done that."
These are the things I've always done for my guys and it definitely pays off for them.
