The Role of Furosemide Stress Test in the Intensive Care Clinic

Summary

AKI causes high mortality and morbidity, especially in critically ill patients, and prolongs the patient's stay in the intensive care unit. Due to the high morbidity and mortality associated with AKI, many researchers are studying several new biomarkers for earlier detection of AKI, determination of etiologies, and prediction of outcomes. However, the use of these new biomarkers may be limited due to reimbursement issues. In addition to the therapeutic role of furosemide in fluid balance, blood pressure control, and hypercalcemia management, Chawla et al. recommend the furosemide stress test (FST) as a tool to predict AKI progression. Designing a test that predicts the probability of AKI progression will help us make better decisions regarding the optimal timing of RRT initiation. In this study, we aimed to evaluate the feasibility of using the FST test in determining the progression of AKI in patients hospitalized in the intensive care unit and the need for RRT using the noninvasive procedure furosemide stress test.
