Acute Kidney Injury Clinical Trial
Official title:
The Diagnostic Value of Contrast-enhanced Ultrasound in Acute Kidney Injury in Intensive Care Unit
The goal of this observational study is to quantitatively assess the renal microcirculation changes by contrast-enhanced ultrasound (CEUS) and to obtain systemic hemodynamic information by ultrasound Doppler at the same time, to analyze the relationship between renal microcirculation changes and systemic hemodynamic changes, and to explore the diagnostic value of CEUS in critically ill acute kidney injury.
The main questions it aims to answer are: 1. To explore the quantitative parameters of contrast-enhanced ultrasound which can reflect the changes of renal microcirculation。 2. To explore the relationship between renal microcirculation and systemic hemodynamics。 3. To explore the value of quantitative evaluation of renal microcirculation changes by contrast-enhanced ultrasound in the diagnosis of acute kidney injury ;
