AliRae:
I am so thankful for your willingness to care for the kids who are outside the boundaries of the good ol' USA. I can not even begin to imagine caring for such sick kids who would easily meet ICU criteria without the modern "technologies" we use daily. I suppose you have to refer back to that great nursing skill of patient assessment and actually look, listen and feel, instead of having your eyes peeled to numbers across a screen.
You are right about being concerned about the ethics of your little patient. However, under the circumstances, were there any other choices? Where else could they have gone? Of course, pallative care is an option. As long as the family understands the limitations of the surgical intervention, you are doing all you can do.
Press on and Godspeed
