CONTEXT Although acute renal failure (ARF) is believed to be common in the setting of critical illness and is associated with a high risk of death, little is known about its epidemiology and outcome or how these vary in different regions of the world. OBJECTIVES To determine the period prevalence of ARF in intensive care unit (ICU) patients in multiple(More)
OBJECTIVE According to recent research, diuretics may increase mortality in acute renal failure patients. The administration of diuretics in such patients has been discouraged. Our objective was to determine the impact of diuretics on the mortality rate of critically ill patients with acute renal failure. DESIGN Prospective, multiple-center, multinational(More)
OBJECTIVE Sepsis is the most common trigger for acute kidney injury (AKI) in critically ill patients. We sought to determine whether there are unique patterns to plasma and urine neutrophil gelatinase-associated lipocalin (NGAL) in septic compared with non-septic AKI. DESIGN Prospective observational study. SETTING Two adult ICUs in Melbourne,(More)
INTRODUCTION The aim of the present study is to understand the nature of acid-base disorders in critically ill patients with acute renal failure (ARF) using the biophysical principles described by Stewart and Figge. A retrospective controlled study was carried out in the intensive care unit of a tertiary hospital. MATERIALS AND METHODS Forty patients with(More)
PURPOSE The aim of this study is to evaluate the relationship between timing of renal replacement therapy (RRT) in severe acute kidney injury and clinical outcomes. METHODS This was a prospective multicenter observational study conducted at 54 intensive care units (ICUs) in 23 countries enrolling 1238 patients. RESULTS Timing of RRT was stratified into(More)
OBJECTIVE Several different severity scoring systems specific to acute renal failure have been proposed. However, most validation studies of these scoring systems were conducted in a single center or in a small number of centers, often the same ones used for their development. Therefore, it is not known whether such severity scoring systems may be widely(More)
BACKGROUND The RIFLE classification scheme for acute kidney injury (AKI) is based on relative changes in serum creatinine (SCr) and on urine output. The SCr criteria, therefore, require a pre-morbid baseline value. When unknown, current recommendations are to estimate a baseline SCr by the MDRD equation. However, the MDRD approach assumes a glomerular(More)
BACKGROUND AND OBJECTIVES Many clinicians believe that low-dose dopamine (LDD) [2 micro g/kg/min] increases renal blood flow (RBF) and medium-dose norepinephrine (MD-NE) [0.4 micro g/kg/min] decreases RBF. They also believe that MD-NE might induce mesenteric and/or coronary ischemia. In fact, the effects of these drugs on renal and vital organ blood flow(More)
INTRODUCTION Metabolic acidosis is common in patients with cardiac arrest and is conventionally considered to be essentially due to hyperlactatemia. However, hyperlactatemia alone fails to explain the cause of metabolic acidosis. Recently, the Stewart-Figge methodology has been found to be useful in explaining and quantifying acid-base changes in various(More)
PURPOSE The benefit of tranexamic acid (TXA) in pediatric cardiac surgery on postoperative bleeding has varied among studies. It is also unclear whether the effects of TXA differ between cyanotic patients and acyanotic patients. The aim of this study was to test the benefit of TXA in pediatric cardiac surgery in a well-balanced study population of cyanotic(More)
