You handled it well, Mspring. When someone is that angry and frustrated, nothing you can say will work.
We had something similar happen the other day. My patient coded (not totally unexpected, but we expected a respiratory failure requiring a vent, not a VT arrest.) We call the family, say dad's not doing well, had to do CPR, he's on a vent, yes you should come now. Not later, now.
They show up, dad's vented and hasn't seen a BP north of 80 in a couple hours despite 3 maxed out pressors. We tell them we've consulted everybody and we're doing all we can- what would dad want us to do? Of course, the answer is "he never said, but we want everything done." OK, we'll do our best. But then they got irritated with us...
"Well, I don't understand why the cardiologist isn't here right now." Well, ma'am, he isn't in the hospital at 3:00 Sunday morning. We called him, did all the tests he wanted, the results of many aren't back yet, and he's coming in from home because we can't figure out why this person arrested with no EKG changes and negative cardiac enzymes (pre-arrest, but after 2 days of being ill.)
The cardiologist arrived within 90 minutes of being called. That wasn't good enough. I know they were under stress but come on! We had pulmonary, CT surgery, renal, and cardiology consults at the bedside within 2 hours of the arrest, in the middle of the night. I thought we did darn well. Must have, he made it.
