Is this trial a fit for you?

Likely a good fit

Ideal candidates are ICU patients aged 18 and older with stage 2 or 3 AKI and preserved urine production.

Probably not a fit

Patients requiring emergency dialysis or those with allergies to contrast media will not benefit from this study.

What this trial studies

This study examines the physiological changes in the kidneys of ICU patients suffering from acute kidney injury (AKI) when starting continuous renal replacement therapy (CRRT) at different blood pressure levels. By enrolling 20 patients, the research aims to determine the optimal blood pressure for kidney function during dialysis using a retrograde renal vein thermodilution technique. Additionally, the study will validate this invasive method with contrast-enhanced ultrasound of the kidneys to provide a comprehensive understanding of renal physiology during treatment.

Why it matters

Potential benefit: If successful, this study could lead to improved dialysis protocols that enhance kidney function and patient outcomes in ICU settings.

How similar studies have gone: While there is conflicting data on dialysis timing, this specific investigation into renal physiology during CRRT at varying blood pressures is novel and has not been extensively studied.
