Background: Renal resistive index (RRI) has been used to evaluate renal blood flow. Our
aim was to investigate the relation between RRI and global tissue hypoperfusion indices …

Materials and Methods: This prospective observational cohort study included two cohorts of
patients, with and without shock less than 24-h after intensive care admission. Apart from …

We read with great interest the guidelines for acute kidney injury management published in
Am J Respir Crit Care Med 2010 [1]. In the section entitled ''How should we assess renal …

Background The predictive role of D oppler R enal R esistive I ndex (RRI) for mortality was
shown in chronic kidney disease. In selected populations of intensive care unit (ICU), RRI …

Background We reported a case of early detection of peripheral hypoperfusion trough the
evaluation of a new index in intensive care: Renal Doppler Resistive Index (RRI). Case …

Abstract Background The renal Doppler resistive index (renal RI) is a noninvasive tool that
has been used to assess renal perfusion in the intensive care unit (ICU) setting. However …

Background Acute kidney injury (AKI) complicates shock. Diagnosis is based on rising
creatinine, a late phenomenon. Intrarenal vasoconstriction occurs earlier. Measuring flow …

Objective Because acute renal failure (ARF) is frequent in septic shock, an early marker of
ARF could impact on management of such patients. High renal arterial resistive index (RI) is …

Purpose: Growing evidence shows the complex interaction between lung and kidney in
critically ill patients. The renal resistive index (RRI) is a bedside measurement of the …

Objectives: To assess renal resistive index variations in response to fluid challenge. Design:
Prospective cohort study. Setting: Three ICUs in French teaching hospitals. Patients …
