Furosemide Stress Test Use in Children at Risk for Acute Kidney Injury.

ABSTRACT:

Introduction

The furosemide stress test (FST) is used to assess urine flow rate (UFR) after a furosemide bolus. FST predicts severe acute kidney injury (AKI) and renal replacement therapy (RRT) receipt in adults, with limited data in pediatric intensive care unit (PICU) patients. We implemented AKI risk stratification using the renal angina index (RAI) with urine neutrophil gelatinase-associated lipocalin (uNGAL) to guide FST in high-risk children but have not evaluated outcomes.

Methods

We combined 2 prospective, observational studies of high AKI risk PICU patients (RAI+: ≥ 8, uNGAL+: ≥ 150 ng/ml). We compared patients who underwent FST (≥ 0.75 mg/kg i.v. furosemide) in the first week versus those who did not, and FST responders (≥ 3 ml/kg/h UFR over 4 hours) versus nonresp
