Evaluation of the Renal Congestion, Perfusion and Function Before and After Diuretic Treatment in the ICU

Evaluation of the Renal Congestion, Perfusion and Function Before and After Diuretic Treatment in the ICU

Renal congestion is a pathological state that can lead to acute kidney failure. Furosemide is known to lower renal congestion by its diuretic effect.

The aim of this trial is to study the reversibility of kidney congestion under diuretic therapy and assess through echodoppler parameters if it can improve renal perfusion and function in congestive ICU patients.

It could in fine lead to a better identification of patients that could benefit from diuretic therapy in the ICU.

Inclusion Criteria:

• patient hospitalized in ICU
• under furosemide treatment

Exclusion Criteria:

• participation refusal
• uncontrolled shock (MAP<65mmHg)
• abdominal compartment syndrome
• diuretic administration in the 6 hours prior to inclusion
• renal replacement therapy or stage 4-5 chronic kidney disease
• atrial fibrillation
• no monitoring of CVP / invasive arterial pressure
