Using renal resistive index to predict acute kidney injury in high-risk patients

Renal Resistive Index as a Predictor of Acute Renal Impairment in High-risk Patients Admitted to Surgical Intensive Care Unit.

Aswan University · NCT06386796

This study is testing if measuring kidney blood flow using ultrasound can help doctors spot acute kidney injury earlier in high-risk patients in the intensive care unit.

What this trial studies

This study investigates the effectiveness of measuring renal resistive index (RRI) via bedside Doppler ultrasound in identifying acute kidney injury (AKI) among high-risk patients in a surgical intensive care unit. It compares RRI with traditional renal biomarkers and assessments such as urine output and serum creatinine levels. The goal is to enhance early detection of AKI, which is crucial for improving patient outcomes in critically ill individuals. The study is conducted at Aswan University Hospital, focusing on patients with conditions like severe pre-eclampsia, polytrauma, and sepsis.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years with severe pre-eclampsia, polytrauma, or sepsis admitted to the ICU.

Not a fit: Patients with known chronic kidney disease, congenital renal anomalies, or those who have undergone renal transplantation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved early detection of acute kidney injury, potentially reducing hospital stays and mortality rates in critically ill patients.

How similar studies have performed: Other studies have explored similar approaches using renal biomarkers for AKI detection, indicating potential for success in this area.
