The clinical relevance of oliguria in the critically ill patient ...
Apr 23, 2020 · Background Urine output is widely used as one of the criteria for the diagnosis and staging of acute renal failure, but few studies have specifically assessed the role of oliguria as a marker of acute renal failure or outcomes in general intensive care unit (ICU) patients. Using a large multinational database, we therefore evaluated the occurrence of oliguria (defined as a …
Identification of an optimal threshold to define oliguria in critically ...
May 30, 2023 · Background The relevance of current consensus threshold to define oliguria has been challenged by small observational studies. We aimed to determine the optimal threshold to define oliguria in critically-ill patients. Methods Cohort study including adult patients admitted within a multi-disciplinary intensive care unit between January 1st 2010 and June 15th 2020. …
Oliguria as predictive biomarker of acute kidney injury in critically ...
Jul 19, 2011 · Introduction During critical illness, oliguria is often used as a biomarker of acute kidney injury (AKI). However, its relationship with the subsequent development of AKI has not been prospectively evaluated. Methods We documented urine output and daily serum creatinine concentration in patients admitted for more than 24 hours in seven intensive care units (ICUs) …
Magnesium Sulfate for Pre-eclampsia and Eclampsia Management …
Oliguria is an element of the disease process [reduced clearance by the kidneys], and not an adverse effect of magnesium sulfate use. Because magnesium is cleared by the kidneys, oliguria of less ...
Association between furosemide administration and outcomes in ...
Mar 4, 2020 · Oliguria still represents one of the two main criteria for the diagnosis of AKI, and it is also the main reason for using diuretics. In our cohort, there were 7244 (82%) patients with AKI according to UO criteria alone. Positive fluid balance is …
Redefining urine output thresholds for acute kidney injury criteria …
Aug 12, 2024 · Introduction The current definition of acute kidney injury (AKI) includes increased serum creatinine (sCr) concentration and decreased urinary output (UO). Recent studies suggest that the standard UO threshold of 0.5 ml/kg/h may be suboptimal. This study aimed to develop and validate a novel UO-based AKI classification system that improves mortality prediction …
Acute kidney injury 2016: diagnosis and diagnostic workup
Sep 27, 2016 · Similarly, oliguria may be an appropriate physiological response of functioning kidneys during periods of prolonged fasting, hypovolaemia, after surgery, and following stress, pain, or trauma [26–28]. In these situations, the action of anti-diuretic hormone (ADH) can result in the generation of very concentrated urine with osmolarities up to ...
Conclusions The widely used cut-o for oliguria of 0.5 ml/kg/h over 6 h may be too conservative. A cut-o of 0.2 ml/ kg/h over 3 or 6 h is supported by the data and should be considered in further denitions of oliguria.

Timing of dialysis in acute kidney injury using routinely collected ...
Nov 28, 2022 · Background and objectives Defining the optimal moment to start renal replacement therapy (RRT) in acute kidney injury (AKI) remains challenging. Multiple randomized controlled trials (RCTs) addressed this question whilst using absolute criteria such as pH or serum potassium. However, there is a need for identification of the most optimal cut-offs of these …
Early-phase cumulative hypotension duration and severe-stage ...
Dec 19, 2016 · This study focused on oliguria, an easy-to-find marker for early-stage AKI in the ICU. In the early phase of oliguric AKI (6 h after the diagnosis of oliguric AKI), we investigated the association between cumulative hypotension duration below threshold MAP and progression of AKI among critically ill patients with and without sepsis.
