The Performance of Renal Doppler Ultrasound in Predicting Outcome of Dialysis Weaning

The Performance of Renal Doppler Ultrasound in Predicting Outcome of Dialysis Weaning

Acute kidney injury (AKI) is a frequent problem in the intensive care unit (ICU) affecting more than 50 % of patients. AKI is associated with several adverse outcomes, including increased mortality and increased length of ICU- and hospital stay, in particular in patients requiring Renal Replacement Therapy (RRT).

Choosing the optimal time for attempting liberation from RRT is still unclear. With this study, we will describe the ability of renal ultrasound in predicting the outcome of dialysis weaning.

Inclusion Criteria:

• All patients ≥ 18 years admitted to the ICU, Aarhus University Hospital who are treated with dialysis as continuous renal placement therapy (CRRT) and planned to undergo dialysis weaning

Exclusion Criteria:

• Insufficient ultrasonographic imaging of the kidneys
• Known morphological kidney disease
• Previous need of chronic RRT
• Prior participation in the study
• Need of extracorporeal membrane oxygenation (ECMO) or other heart assist device
