Values are expressed as mean + standard deviation. AKI:cute kidney injury; CRRT, continuous renal replacement therapy. BMI, body mass index; ALB, serum albumin; eGFR: estimated glomerular filtration; HGB, hemoglobin; CRP: c-reactive protein; IABP: intra-aortic balloon pumping; CAI:catecholamine index; P/F, PaO2/ FiO2.
