Clinical Trial Summary

The goal of this study is to quantitatively assess renal microcirculation changes by contrast-enhanced ultrasound 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 its predictive value in renal function recovery in patients with critical 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 renal microflow changes quantitatively evaluated by contrast-enhanced ultrasound in predicting renal function recovery.

Description:

Quantitative analysis of cortical perfusion by contrast-enhanced ultrasound； Echocardiography； Quantitative results of renal artery and vein spectrum

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Serum creatinine values and/or urine output	Complete recovery (defined as a return to normal serum creatinine and urine volume) and reversal of acute kidney injury (AKI) (more than 50% improvement in serum creatinine and/or urine volume from baseline), non-recovery included persistent AKI(no significant improvement or further increase in serum creatinine and/or urine volume, the need for dialysis, or death.)	Through study completion, an average of 7 days
