Overview
Acute kidney injury (AKI) is a well-recognized complication in critically ill patients, which often leads to the necessity of mechanical kidney support (CRRT).
In current therapeutic regimes, CRRT is used to strictly prevent azotaemia. Thus recent clinical observations, as well as data from animal testing suggest a link between controlled azotaemia and faster renal recovery in AKI patients.
The aim of the study is to improve renal recovery.
