As I mentioned previously, Remi is a little less blunt than I am.
I don't let my emotions dictate my actions - never have in the 40 years I've been in healthcare. Maybe we're a lot alike and just arguing to argue. But there are certainly patients that are more stressful than others. My first arrest as a new EMT decades ago was a five year old child out in the middle of BFE. It's quite stressful to realize you're very likely not going to be able to do squat for this child. One of my last was a 19yr old girl in profound respiratory distress that arrested on the way to the hospital. We coded her for three hours (no thumpers back then - it was all old-fashioned CPR) in the ER until it was determined she'd had a massive PE likely due to her concomitant smoking and BCP use. That significantly affected everyone involved from ER doc to EMT.
I find it quite odd that people think that arrests shouldn't be stressful to a certain extent because there is usually an expectation that something can be done, but again, we have different perspectives and different responsibilities. Do A, do B, do C, do D, repeat as necessary is not the norm in my world. I assume most patients on whom you run a code, with some exceptions, have already arrested. That is not the case in my business. My patients are all quite alive when they come to me, although some are already in deep trouble from sepsis, trauma, etc. I sometimes have patients with nearly all the "H's and T's" at the same time. I know what to do - I don't hesitate - but that doesn't mean it's not stressful.
