Renal Resistive Index as a Predictor of Acute Kidney Injury and Evaluation of Fluid Administration in Sepsis

Renal Resistive Index by Renal Doppler Ultrasound as a Predictor of Acute Kidney Injury and Evaluation of Fluid Administration in Sepsis Patients: Cohort Study

We aim from this study to investigate the role of renal resistance index (RRI) in evaluation of Acute kidney injury development and fluid administration in sepsis patients considering the change in RRI values over 7 days from admission as a predictor of AKI development

Acute kidney injury (AKI) is one of the most common problems in critically ill patients in the clinic. AKI can be caused by various factors, such as hypovolemia, shock, major surgery, trauma, and heart failure, of which sepsis is the most common

Inclusion Criteria:

• Age over 21 years
• meet Sepsis 3 criteria (potential source of infection , host response and organ dysfunction) but not in septic shock.

Exclusion Criteria:

• patients during pregnancy.
• patients with hepatorenal syndrome.
• Poor abdominal echogenicity eg.(morbid obesity ,increase intra abdominal pressure )
• Severe acute or chronic renal insufficiency .
• Dialysis dependency.
• Renal transplantation.
• Known renal artery stenosis.
• Mono-kidney, kidney tumor, anatomic kidney abnormalities.
