Two terms which confuse me are "cardiorenal" and "volume loss ATN".
Cardiorenal: I was talking to other interns who felt Cardiorenal just meant pre-renal AKI. I was under the impression it could be a fluid underload, overload and could be renal or cardiac in origin. Any good sources to iron out all the mechanisms and what to do in each case?
Volume loss ATN: So my impression was volume loss in an acute bleed for example would lead to a pre-renal AKI. However, I literally read this in a note today. "Random urine sodium and creatinine showed pre renal, volume loss ATN most likely based on microscopy"..so I thought ATN was a intrarenal cause of AKI which is a different entity. I know lack of perfusion leads to necrosis physiologically, but if someone could clarify the terms, that would be great.
