Hi my allnurses friends
I admitted a stable, extubated post op ASD repair yesterday afternoon. Pt's first K level was 3.1. Over the course of 5 hours it rose to 5.9 with no extra potassium being given except the 20 meq that was in the liter of her IVF. When the pt's K hit 4.7 we changed the fluids and took the potassium out, but it still increased. Of course the pt hit 5.9 around shift change... The NP ordered a dose of lasix while they investigated this further.
Apparently the pt did well overnight after that dose of lasix was given, but early in the am the pt's K levels were slowly starting to climb again. The attending that was on decided that the pt had a cardioplegia leak, which I have no idea what he meant. The NP that relayed this to me also didn't know what the attending meant. I have tried to google "cardioplegia leak after CPB" and I get no answers... anyone ever heard of this or know what my attending might have meant??
Thanks for any insight or help you can give
