We lost a 2 year old boy in the ER last night. Cardiac arrest in the door, amb said negative heart rate. 1140 arrival cpr, 4 doses of atropine, defib, the works and 2 beats. That's it. Doc called it at 1220. Up to that point I had been mechanical and precise, even at TOD I was like well we did what we could. When he told the mother the sound she made was the horrible thing I've ever heard. How does this even happen? The worst thing is I know this won't be the last time I see this.
