Brief summary

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.

Interventions

OTHEREffluent dose of CRRT

The effluent dose of the CRRT will be performed according to study group for 7 days or up to the end of CRRT, whatever occurs first.
