I've been a part of a failed resuscitation of a 38 wk EGA crash section due to abruption. It was difficult to handle, especially after spending a block on the NICU resuscitating babies much much younger with much more morbidity/mortality. If you can do the hard ones, why not the easy one, right?
anyway, you hafta look at it like this-- the kid without you has no chance. We gave our kiddo the best chance possible to survive-- and unfortunately things didn't work out. It doesn't make it easier, but it does let you put things into perspective. You can give the kid all the chances in the world, but if it's not meant to be, it's not meant to be. Practice up and try to save the next one.
My only other pediatric death experiences were not unexpected-- which makes it easier. One was an adolescent with lyphoma, another was a 24 wk EGA with sepsis. Both were hard, but in different ways.
the best thing to do is to grab a few people who were there with you and talk about it. it's good to vent a little and know you have the right to be upset.
