Data are given as medians with interquartile range, or absolute number of patients with percentage of the total population. ^aAll patients had a full recovery of renal function at hospital discharge. ^bIn an additional two patients renal replacement therapy was indicated but not performed because it was considered futile. ^cHydrocortisone treatment was initiated for relative adrenal insufficiency. APACHE, Acute Physiology and Chronic Health Evaluation; CVC infection, central venous catheter related infection; ICU, intensive care unit; NS, non-significant.
