diagnoses of exclusion

it's kind of like a process of elimination, only less simple.... it's been a difficult afternoon here, and we're not quite sure what's going on. i suppose that theme has been developing since wednesday, but the frustration with not knowing is now running alongside some worsening of isaiah's condition. when he is awake, he is very agitated. when he's agitated, his blood pressure rises to unacceptable levels, so with reluctance, we've been sedating him more. as we wait for one of the medical services to step up and claim his issues as a result of a failure in the system in which they specialize in, we can see each of their points when they say that, based on the data, their system isn't failing. but something is wrong. so the process basically involves keeping him comfortable and waiting to see if there is an infection lurking somewhere- and things are excluded along the way. but nothing gets excluded to the point of being off the table. our fear tonight is that it's his cardiac plumbing- which may just not be good enough to tolerate everything that is happening. stay tuned, if you want. no one on this end is going to blame anyone on that end if they want to look away. we'll keep posting.
