NCT06353659

Brief Summary

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.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Acute kidney injury (according to KDIGO 2012 criteria)

    Acute kidney injury occur or not

    Through study completion, an average of 7 days

Study Arms (2)

Patients with acute kidney injury (AKI)

Patient diagnosed with AKI according to kidney disease improving global outcomes (KDIGO) 2012 criteria

Diagnostic Test: Contrast-enhanced Ultrasound

Patients without AKI

Patient diagnosed without AKI according to kidney disease improving global outcomes (KDIGO) 2012 criteria

Diagnostic Test: Contrast-enhanced Ultrasound

Interventions

Patients with acute kidney injury high risk factors (KDIGO 2012) will undergo a contrast-enhanced ultrasound within 24 hours of admission to the ICU

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Through literature review, the latest meta-analysis results showed that the area under the curve of CEUS parameters for diagnosing AKI was 0.84 and the width of the confidence interval was 0.22. When α=0.05, the sample size N=54 was obtained by PASS software. Considering the 10% shedding rate, 60 patients were expected to be enrolled in this study.

You may qualify if:

  • Age\>18 years old
  • First admission to ICU \< 24h after admission and expected ICU stay ≥48 hours
  • Acute kidney injury risk factors (KDIGO 2012)
  • Contrast-enhanced ultrasound

You may not qualify if:

  • Known severe chronic kidney disease (CKD≥ stage 4) or undergoing hemodialysis treatment
  • Kidney transplantation or renal malignancy
  • Terminal stage of malignant tumor
  • Pregnancy
  • Renal artery stenosis or renal vein thrombosis
  • The quality of CEUS images is poor, and quantitative analysis cannot be performed
