Hi, wanted to get some opinions on a recent very interesting patient that I had:Pt. was originally admitted to the floor with chest pain and RVR (both of which resolved in ER once nitro gtt was started). Apparently when he arrived on the floor, the charge there took one look at him and decided he didn't belong there, so I get him in ICU. When he arrives on our unit, he's looks to be about 15 mins from the wrong exit out of ICU (grey, sweatier than I've ever seen anybody, totally clamped down). SBP in the 70s, and of course, no IV access (the field start was infiltrated upon arrival). We quickly get a line in, start 3L NS boluses, and get a stat echo ordered. Echo shows sig right ventricular dilation and nearly no blood movement (which was new since the guys last echo, about 1mo ago). I start Neo which quickly gets up to 300mcg and vasopressin 0.04u/min per the intensivist who's hanging out in the room. We head for the newly ordered CT c contrast: guy has a massive PE. I'll mention here that this entire time, the guy is on 2L, sats 98ish, rate in the low 20s. So, we TPA him, and by 3am he's much improved. I didn't get a chance to ask the intensivist, or the cardiologist who was his first consult, why we didn't head for Levo. We use it all the time and it's usually our firstline pressor. Even when I was maxed out on Neo and vasopressin with MAPs in the 50s, it wasn't even brought up. I've done some research trying to look the reasoning up, but haven't been able to find anything. Any ideas? Pt has history of CAD, stent x2 in circ, HTN, no pulmonary disease to speak of, and chronic a-fib.
Might have been that this wasn't a completely "acute" issue. Most likely developed over time and eventually got to the point where he had chest pain from his heart not getting the o2 it needed, got mad and went into RVR. Coronaries dilated with the Nitro supplying "more" o2 calming it down. just a temp fix though....but the PE kept on, most likely causing some muscles, organs, etc...to build up some acidosis due to hypoxia, hence another reason for the low bp and the reason why you gave some boluses too...Lungs usually the LAST to decompensate and thats most likely the reason why sats weren't as bad or RR effort not terrible.....RR rate was in the 20's to blow off the acidosis.....ABG/enzymes/ along with a CXR could've ruled out cardiac issues without even really doing an echo i would think....but given his cardiac hx I could see why one would think MI VS a million other things.....another thing that would've been interesting to see was if you had a CVP....
