Study Overview
Brief Summary
Acute kidney injury (AKI) is one of the most important factors associated with increased mortality in patients with acute-on-chronic liver failure (AoCLF). Early identification and treatment of this subgroup of patients may improve survival and decrease ICU length of stay. As kidney ischemia is one of the main mechanisms responsible for AKI in AoCLF, an increase in urinary to arterial partial pressure of oxygen may help in the early diagnosis of renal failure. For this arterial and urinary oxygen pressure will be measured at ICU admission, on day 1 and day 3 of ICU stay. Diagnosis of AKI within the first 28 days after ICU admission will be recorded
